Shareholders’ Agreements and Corporate Arbitration under Turkish Law

Shareholders’ agreements play a central role in joint ventures, private equity investments, family-owned companies, start-ups, strategic partnerships and cross-border acquisitions involving Turkish companies.

The articles of association of a company establish its registered corporate structure. A shareholders’ agreement, by contrast, enables some or all shareholders to regulate their commercial relationship in greater detail. It may address matters such as management rights, voting arrangements, reserved decisions, financing obligations, share transfers, minority protection, confidentiality, non-compete obligations, deadlock and exit mechanisms.

A well-drafted shareholders’ agreement may significantly reduce uncertainty. However, the effectiveness of the agreement depends not only on the wording of its commercial provisions but also on whether those provisions are consistent with mandatory Turkish company law and can be enforced against the relevant parties.

Dispute resolution is especially important. Shareholder disputes often arise when the relationship has already deteriorated, the company’s management is paralysed or one party is attempting to transfer its shares. Ordinary court litigation may be public, lengthy and insufficiently flexible for disputes requiring urgent or commercially sophisticated remedies.

Corporate arbitration may provide confidentiality, specialist arbitrators, procedural flexibility and international enforceability. Nevertheless, not every corporate dispute is necessarily capable of settlement by arbitration under Turkish law. Claims affecting the company’s legal status, commercial registry, all shareholders, creditors or persons that did not consent to arbitration create particular difficulties.

This article explains the legal nature of shareholders’ agreements, their relationship with the articles of association, commonly used shareholder protections, the scope of corporate arbitration, arbitrability limitations, non-signatory problems, interim measures and the enforcement of corporate arbitral awards under Turkish law.

What Is a Shareholders’ Agreement?

A shareholders’ agreement is a private contract under which shareholders regulate how they will exercise their rights, perform their obligations and manage their investment in a company.

Turkish legislation does not provide a single statutory form or comprehensive special regime for shareholders’ agreements. They are generally structured within the principle of freedom of contract. Article 26 of the Turkish Code of Obligations permits parties to determine the contents of their contract within the boundaries established by law.

A shareholders’ agreement may therefore combine several contractual elements, including:

• Voting commitments;
• Management and nomination rights;
• Share transfer obligations;
• Options;
• Pre-emption rights;
• Financing commitments;
• Confidentiality obligations;
• Non-compete and non-solicitation provisions;
• Indemnities;
• Exit arrangements;
• Dispute resolution mechanisms.

The agreement may be signed by all shareholders or only by certain shareholders. The company may also become a party, although making the company a signatory does not permit the parties to override mandatory rules governing corporate organs, capital protection, shareholders’ statutory rights or commercial registry requirements.

The agreement should identify the parties accurately and state whether it binds their permitted successors, transferees and affiliates. Each future shareholder expected to benefit from or be subject to the agreement should ordinarily be required to sign a deed of adherence or another legally effective accession document.

Shareholders’ Agreement and Articles of Association

A shareholders’ agreement and the company’s articles of association perform different legal functions.

The articles of association are the company’s constitutional document. They are registered with the commercial registry and govern the company’s formal corporate structure within the limits of the Turkish Commercial Code.

A shareholders’ agreement is ordinarily a private contractual arrangement between its signatories. Unless the company and other shareholders have validly consented, the agreement does not automatically bind every shareholder, future shareholder, corporate organ or third party.

This distinction creates one of the most important practical rules in Turkish corporate transactions:

A contractual obligation between shareholders does not automatically produce the same corporate-law effect as a provision validly included in the articles of association.

For example, a shareholder may contractually promise to vote for a particular board candidate. If that shareholder breaches the promise, it may incur contractual liability. However, the validity of the corporate resolution adopted at the general assembly must still be examined under the Turkish Commercial Code.

Similarly, shareholders may agree that shares cannot be transferred without the consent of another shareholder. That contractual restriction may be enforceable between the signatories, but its direct effect on the company and the registration of the transferee depends on the applicable statutory and articles-based transfer regime.

Article 340 of the Turkish Commercial Code adopts a restrictive approach for joint-stock company articles. The articles may depart from statutory provisions governing joint-stock companies only where the Code expressly permits such deviation. This rule must be considered when attempting to reproduce detailed shareholders’ agreement provisions in the registered articles.

The most effective approach is usually to coordinate the two documents. Matters capable of valid inclusion in the articles should be reflected there, while more detailed commercial, financial and personal obligations may remain in the shareholders’ agreement.

Why Use Arbitration for Shareholder Disputes?

Corporate disputes may involve sensitive commercial and personal issues, such as:

• Alleged misuse of company funds;
• Exclusion of a minority shareholder;
• Breach of a voting agreement;
• Disputed share transfers;
• Failure to complete an exit;
• Misrepresentations during an investment;
• Deadlock between equal shareholders;
• Breach of confidentiality;
• Diversion of corporate opportunities;
• Violation of a non-compete obligation;
• Disagreement over valuation;
• Failure to provide additional financing.

Arbitration can offer several advantages.

The parties may select arbitrators with experience in Turkish company law, mergers and acquisitions, valuation, venture capital or the relevant business sector. They may choose English as the language of proceedings and select Istanbul or another jurisdiction as the legal seat.

Arbitration is also generally private. This may protect commercially sensitive information, financial records, trade secrets and internal disagreements from public disclosure.

The parties may design procedures suitable for urgent corporate disputes, including expedited proceedings, interim measures and emergency arbitrator applications.

Where an award must be enforced outside Turkey, international arbitration may also offer an advantage through the New York Convention framework, subject to the law and refusal grounds of the enforcement jurisdiction.

However, these advantages apply only where a valid arbitration agreement exists and the particular dispute is legally arbitrable.

Legal Framework for Corporate Arbitration in Turkey

Where a shareholder dispute contains a foreign element and Turkey is selected as the seat, International Arbitration Law No. 4686 will generally govern the arbitration.

A foreign element may exist where the parties have places of business in different states, foreign capital or international financing is involved, or the underlying transaction causes capital or goods to move between countries. The law excludes disputes concerning rights in rem over Turkish immovable property and disputes that are not subject to the parties’ free disposition.

Domestic arbitrations seated in Turkey are governed by the arbitration provisions of the Turkish Code of Civil Procedure.

Article 408 of the Code provides that disputes arising from rights in rem over immovable property or matters that are not subject to the parties’ will are not arbitrable.

The central test is therefore whether the parties may freely dispose of the right forming the subject matter of the dispute.

A contractual payment or damages claim will usually be more readily arbitrable because the parties may settle, waive or modify it.

A claim seeking a constitutive decision affecting the legal status of the company, all shareholders, creditors or an official registry presents greater difficulty.

The Arbitration Agreement Must Be in Writing

The arbitral tribunal derives its jurisdiction from consent.

Under Article 4 of the International Arbitration Law, an arbitration agreement is an agreement to submit all or some disputes arising from a defined legal relationship to arbitration. It may be included in the main agreement or concluded separately and must satisfy the statutory written-form requirement. Electronic communications and incorporation by reference may satisfy that requirement under the conditions stated in the law.

A shareholders’ agreement should use mandatory language, such as:

“Any dispute arising out of or in connection with this Agreement shall be finally resolved by arbitration.”

Optional wording should be avoided. Expressions stating that the parties “may refer” disputes to arbitration can create uncertainty over whether further consent is required after the dispute arises.

The clause should define whether it covers:

• The formation and validity of the agreement;
• Contractual performance;
• Share transfers;
• Valuation;
• Voting commitments;
• Management rights;
• Confidentiality;
• Non-compete obligations;
• Termination;
• Post-termination rights;
• Non-contractual claims connected with the investment;
• Claims under related transaction documents.

The scope should be broad enough to prevent closely connected claims from being divided between arbitration and litigation.

Share Transfer Disputes

Share transfer restrictions are among the most important provisions in a shareholders’ agreement.

Common mechanisms include:

• Rights of first offer;
• Rights of first refusal;
• Pre-emption rights;
• Call options;
• Put options;
• Lock-up periods;
• Permitted transfers;
• Tag-along rights;
• Drag-along rights;
• Mandatory transfers following default;
• Transfers following death, incapacity or insolvency.

The contractual dispute over whether a shareholder breached one of these obligations will generally be capable of arbitration.

For example, a tribunal may determine:

• Whether a transfer notice complied with the agreement;
• Whether a right of first refusal was triggered;
• Whether an option was exercised validly;
• Whether the agreed valuation formula was applied correctly;
• Whether the transferring shareholder must pay damages;
• Whether a proposed transaction falls within a permitted-transfer exception.

Nevertheless, the tribunal’s power to cause the legal transfer of the shares may depend on the company type, share category, corporate approvals and formal requirements.

For non-listed registered shares in a joint-stock company, the Turkish Commercial Code allows articles-based restrictions and permits the company to refuse approval in specified circumstances. Until required approval is granted, ownership and attached rights may remain with the transferor under the statutory regime.

For limited liability companies, share transfers and transactions creating an obligation to transfer must be made in writing with notarised signatures. Unless the company agreement provides otherwise, general assembly approval is required and the transfer becomes effective through that approval.

Accordingly, an arbitral award directing a contractual party to sign transfer documents may not, by itself, eliminate every corporate approval or registration requirement.

The arbitration clause should permit the tribunal to order specific performance, execution of documents and damages, while recognising that necessary corporate and registry steps must still be completed under mandatory law.

Drag-Along Rights

A drag-along clause allows a specified shareholder or shareholder group to require other shareholders to sell their shares to a third-party purchaser.

The provision is commonly used to prevent minority shareholders from blocking the sale of the entire company.

A properly drafted drag-along clause should determine:

• The percentage required to trigger the right;
• Whether the sale must involve all shares;
• The minimum price or valuation standard;
• The terms that must apply equally to all shareholders;
• Representations required from minority shareholders;
• Limits on minority liability;
• The procedure for giving notice;
• The completion timetable;
• The consequences of non-cooperation;
• The authority to sign documents where legally permissible.

An arbitration may determine whether the drag-along right was triggered and whether the resisting shareholder breached its contractual obligations.

However, the award must operate within applicable corporate and formal transfer rules. A tribunal cannot automatically bind a purchaser, company, registry or shareholder that did not consent to arbitration.

The clause should therefore include contractual powers of attorney, escrow arrangements, accession obligations and specific-performance remedies to the extent permitted by Turkish law.

Tag-Along Rights

A tag-along clause protects minority shareholders when a controlling shareholder proposes to sell its shares.

It usually allows the minority to require the purchaser to acquire some or all of the minority’s shares on equivalent terms.

Disputes may concern:

• Whether the transaction triggered the tag right;
• Whether an indirect sale or change of control is included;
• Whether the minority received proper notice;
• Whether the consideration and terms were genuinely equivalent;
• Whether deferred or contingent consideration was allocated fairly;
• Whether the controlling shareholder may complete without procuring the minority sale.

These disputes are principally contractual and will ordinarily be suitable for arbitration where all relevant parties are bound.

The agreement should prevent the controlling shareholder from completing the proposed sale until the tag-along procedure has been satisfied.

Voting Agreements and Reserved Matters

Shareholders frequently agree to vote in a particular manner on specified issues.

The agreement may require consent from an investor, minority shareholder or qualified majority before the company takes decisions concerning:

• Capital increases;
• New share issuances;
• Borrowing above a threshold;
• Acquisitions and disposals;
• Business-plan approval;
• Related-party transactions;
• Dividend distribution;
• Appointment of senior management;
• Material litigation;
• Changes to the company’s activities;
• Liquidation or sale of the business.

A voting covenant is generally enforceable as a contractual obligation between the signatories. A breach may result in damages, contractual penalties or another remedy available under the agreement.

However, contractual control of voting must be distinguished from the statutory powers of corporate organs.

The shareholders cannot contractually convert a legally non-delegable authority of the board or general assembly into a power belonging to a different person. The company’s directors must also continue to comply with their statutory duties and cannot justify an unlawful decision merely by referring to the shareholders’ agreement.

For limited liability companies, Article 616 expressly identifies non-delegable powers of the general assembly, including amendments to the company agreement, appointment and dismissal of managers, approval of financial statements, profit distribution, approval of share transfers and dissolution.

Reserved-matter provisions should therefore be drafted as shareholder-level consent and voting obligations rather than as an attempt to abolish mandatory corporate authority.

Board Nomination and Management Rights

A shareholders’ agreement may grant a shareholder the right to nominate one or more board members.

The relevant provisions should regulate:

• The number of nomination rights;
• Qualification requirements;
• Replacement and removal;
• Observer rights;
• Quorum;
• Board committees;
• Information rights;
• Conflicts of interest;
• Reserved board matters.

The contractual parties may be required to use their voting rights to procure the appointment of a nominee. However, the nominee does not become the appointing shareholder’s representative in the legal sense.

Once appointed, a director owes statutory duties within the company’s legal structure. A shareholder cannot require the director to act unlawfully, disregard the company’s interests or breach mandatory duties.

A tribunal may determine that a shareholder failed to support the nomination or removal process as contractually required. The validity of the corporate appointment itself must still be assessed under the Turkish Commercial Code and the company’s articles.

Deadlock Provisions

Deadlock is particularly common in companies owned equally by two shareholder groups.

A deadlock may arise where:

• The board cannot reach the required majority;
• The general assembly cannot approve a reserved matter;
• A business plan or budget is rejected repeatedly;
• Shareholders disagree over financing;
• One side blocks essential company operations.

A shareholders’ agreement should define deadlock precisely. A single disagreement should not necessarily trigger an immediate compulsory exit.

A typical multi-stage procedure may include:

1. Formal deadlock notice;
2. Negotiations between senior representatives;
3. Mediation;
4. Expert determination for technical or accounting issues;
5. A buy-sell or exit mechanism;
6. Arbitration concerning whether the mechanism was triggered or implemented correctly.

Exit mechanisms may include:

• Russian roulette clauses;
• Texas shoot-out clauses;
• Sealed-bid procedures;
• Put and call options;
• Third-party sale processes;
• Liquidation as a final contractual alternative.

The mechanism should address funding ability, valuation fairness, timing, security, competition approvals and the risk of strategic abuse.

A tribunal can determine contractual compliance, but a clause attempting to authorise the tribunal to dissolve the company directly may face arbitrability concerns.

General Assembly Resolutions

Claims concerning the annulment or nullity of general assembly resolutions require special caution.

Article 445 of the Turkish Commercial Code provides that specified persons may bring an annulment action against resolutions contrary to the law, articles of association or good-faith principles within three months before the Commercial Court of First Instance at the company’s registered seat.

Article 447 identifies categories of general assembly resolutions that are null, including resolutions unlawfully restricting indispensable shareholder rights or violating the company’s fundamental structure and capital-protection rules.

The statutory framework also gives these proceedings consequences extending beyond the individual claimant. Under Article 450, a final court judgment annulling or declaring the nullity of a general assembly resolution is effective against all shareholders and must be registered with the commercial registry.

These collective and registry-related effects create serious arbitrability concerns.

An arbitral tribunal derives jurisdiction from the consent of the parties, while an annulment judgment under Article 450 affects all shareholders, including persons that may not have agreed to arbitrate.

For this reason, the safer and more conservative approach is to reserve statutory annulment and nullity actions for the competent Turkish commercial court.

The tribunal may still decide related contractual questions. For example, it may determine that a shareholder breached a voting commitment or owes damages because of how it voted. That contractual decision is different from annulling the corporate resolution with effect against every shareholder.

Just-Cause Dissolution of a Company

A similar difficulty arises with an action for dissolution on just grounds.

Under Article 531 of the Turkish Commercial Code, qualifying minority shareholders may request dissolution of a joint-stock company from the Commercial Court of First Instance at the company’s registered seat. Instead of dissolution, the court may order the claimant’s shares to be purchased at their real value or adopt another appropriate solution.

This is a statutory corporate remedy that may alter the legal existence or ownership structure of the company and affect shareholders and creditors.

A shareholders’ agreement may contain contractual exit mechanisms intended to avoid such litigation. An arbitral tribunal may enforce a put option, valuation mechanism or contractual buy-out between the parties.

However, an arbitral award purporting to dissolve the company under the statutory Article 531 mechanism would face a substantial arbitrability risk.

The parties should distinguish clearly between:

• A contractual exit or compulsory share purchase; and
• A statutory action seeking a constitutive court decision concerning the company.

Directors’ Liability Claims

The Turkish Commercial Code imposes liability on founders, directors, managers and liquidators for damage caused through breach of duties arising from law or the articles.

Article 553 recognises potential liability towards the company, shareholders and creditors. Article 555 permits both the company and individual shareholders to seek compensation for loss suffered by the company, although a shareholder bringing such a claim must request payment to the company.

The arbitrability of a directors’ liability claim requires detailed analysis.

A direct contractual claim against a director who personally signed the shareholders’ agreement may be arbitrable.

A statutory corporate claim is more complicated where:

• The company is not bound by the arbitration agreement;
• The claimant acts on behalf of the company;
• Creditors possess independent statutory rights;
• The requested relief belongs to the company;
• Other shareholders may be affected.

The arbitration clause should not assume automatically that every statutory director-liability action falls within a shareholders’ agreement.

The company, relevant directors and shareholders should sign compatible arbitration agreements where the parties intend such claims to be arbitrated, subject always to mandatory law and third-party rights.

The Company as a Party to the Shareholders’ Agreement

Making the company a party can reduce some enforcement difficulties.

The company may agree contractually to:

• Provide information;
• Facilitate permitted transfers;
• Observe agreed procedures;
• Maintain confidentiality;
• Accede to the arbitration clause;
• Participate in related proceedings.

However, company participation does not validate obligations contrary to mandatory law.

The company cannot contract out of capital-maintenance rules, eliminate non-delegable organ powers or deprive non-consenting shareholders and creditors of statutory rights.

The board must evaluate each act under its legal duties. A contractual obligation cannot require directors to register an invalid share transfer, distribute unlawful dividends or implement a resolution contrary to the Turkish Commercial Code.

Arbitration Clauses in the Articles of Association

Whether an arbitration clause included directly in the articles can bind the company, current shareholders and future shareholders across all corporate disputes is a legally complex issue under Turkish law.

The Turkish Commercial Code does not establish a comprehensive special regime for corporate arbitration clauses comparable to the detailed regimes found in certain other jurisdictions.

Article 340’s mandatory-provisions principle, the written-consent requirement for arbitration and the collective effect of certain corporate claims must all be considered together.

As a practical legal assessment, the validity and scope of an articles-based arbitration clause may depend on:

• The company type;
• The wording of the clause;
• The type of dispute;
• Whether the shareholder expressly consented;
• Whether the company is a party;
• Whether the remedy affects non-signatories;
• Whether the dispute is subject to exclusive court jurisdiction;
• Whether the award would require registry action;
• Whether the claim has effect against all shareholders.

Because Turkish law does not eliminate these uncertainties through a specific statutory corporate-arbitration framework, transaction documents should not rely exclusively on a short arbitration clause in the articles.

The safer structure is generally to obtain express written consent through the shareholders’ agreement, investment agreement, accession deeds and related corporate documents.

Non-Signatory Shareholders and Group Companies

Arbitration is based on consent. A person does not ordinarily become bound merely because it is:

• A shareholder in the same company;
• A parent or subsidiary of a signatory;
• A director;
• A beneficial owner;
• A family member;
• Involved commercially in the transaction.

A parent company guarantee, investment agreement, share purchase agreement and shareholders’ agreement may contain different dispute resolution clauses.

Inconsistent clauses can lead to parallel proceedings and jurisdictional objections.

The parties should coordinate all connected contracts and require each relevant person to sign an appropriate arbitration agreement.

The agreement should also require a transferee to execute a deed of adherence before the transfer is completed. Without accession, the transferee may acquire shares without becoming bound by the shareholders’ agreement or arbitration clause.

Multiparty and Multicontract Disputes

Corporate transactions commonly involve several parties and agreements.

A dispute may involve:

• The founders;
• An institutional investor;
• The company;
• Directors;
• A parent company;
• A guarantor;
• The buyer under a share sale;
• Other group companies.

The arbitration provisions should be compatible regarding:

• Institution;
• Seat;
• Language;
• Number of arbitrators;
• Governing law;
• Joinder;
• Consolidation;
• Service;
• Confidentiality;
• Interim relief.

Selecting institutional arbitration may help where the applicable rules contain procedures for multiparty appointments, joinder or consolidation.

The official ISTAC model clause provides that disputes may be finally resolved under the ISTAC Arbitration Rules and recommends that parties separately specify the seat, language, number of arbitrators and applicable substantive law.

Interim Measures in Corporate Arbitration

Corporate disputes may require urgent protection.

A shareholder may seek to:

• Prevent an unauthorised share transfer;
• Preserve voting rights;
• Stop disclosure of confidential information;
• Prevent dissipation of company assets;
• Preserve accounting records;
• Suspend implementation of a transaction;
• Protect shares from disposal;
• Obtain security for a contractual claim.

Under the International Arbitration Law, applying to a Turkish court for an interim injunction or interim attachment does not violate the arbitration agreement.

The tribunal may also grant interim relief unless the parties agreed otherwise. However, it cannot issue measures requiring compulsory state enforcement, action by public authorities or obligations binding third parties.

This limitation is highly relevant in corporate disputes.

A tribunal may order a shareholder not to transfer shares. It may not be able to bind a non-party purchaser, bank, commercial registry or company that did not consent to arbitration.

Judicial protection may therefore be required where the measure must have external or registry-related effect.

The arbitration clause should preserve access to both emergency arbitration and competent courts.

Remedies Available in Corporate Arbitration

Depending on the applicable law and wording of the agreement, an arbitral tribunal may award:

• Contractual damages;
• Payment of a purchase price;
• Indemnification;
• Contractual penalties;
• Declaratory relief;
• Specific performance;
• Execution of contractual documents;
• Compliance with a transfer procedure;
• Enforcement of confidentiality or non-compete obligations;
• Valuation-based payments;
• Interest and costs.

The requested remedy should be realistic.

Damages may be easier to enforce than an order requiring a complex corporate resolution involving directors, the company, third-party purchasers or the commercial registry.

Specific-performance clauses should be supported through:

• Powers of attorney;
• Escrowed documents;
• Pre-signed transfer instruments where lawful;
• Clear valuation procedures;
• Security arrangements;
• Accession obligations;
• Contractual penalties.

The transaction should be structured so that the award does not depend entirely on the voluntary cooperation of a party that has already breached the agreement.

Setting Aside and Enforcement Risks

An award rendered in a Turkish-seated international arbitration may be challenged under the limited grounds contained in Law No. 4686.

Relevant risks in corporate arbitration include:

• Invalidity of the arbitration agreement;
• A non-signatory being treated as bound without sufficient consent;
• The tribunal deciding a non-arbitrable corporate matter;
• The tribunal granting relief beyond the arbitration clause;
• Failure to include an indispensable party;
• Violation of mandatory corporate rules;
• Conflict with Turkish public policy.

A foreign corporate award may face similar issues when recognition or enforcement is sought in Turkey. Turkish law permits refusal where the subject matter cannot legally be resolved through arbitration.

Parties should therefore evaluate enforceability at the drafting stage rather than after obtaining an award.

Sample Corporate Arbitration Clause

The following clause may be used as a starting point and should be adapted to the transaction:

“Any dispute, controversy or claim arising out of or relating to this Agreement, including its formation, existence, validity, interpretation, performance, breach, termination, share-transfer provisions, valuation mechanisms, voting obligations, management rights, confidentiality obligations and exit arrangements, shall be finally resolved by arbitration administered by the Istanbul Arbitration Centre in accordance with the ISTAC Arbitration Rules.

The seat of arbitration shall be Istanbul, Türkiye. The tribunal shall consist of three arbitrators. The language of arbitration shall be English. This Agreement and the arbitration agreement contained in this clause shall be governed by Turkish law.

The tribunal may order interim relief, specific performance, execution of documents, payment, damages and any other contractual remedy permitted by the applicable law. Nothing in this clause shall prevent a party from applying to an emergency arbitrator or a competent court for urgent interim or conservatory relief.

Statutory corporate claims that are not legally capable of settlement by arbitration, including claims requiring a constitutive judgment binding non-parties, all shareholders, creditors or the commercial registry, shall be brought before the court having mandatory jurisdiction. To the extent legally permissible, all related contracts shall be interpreted to permit consolidation or coordinated determination of connected disputes.”

Practical Drafting Checklist

Before signing a shareholders’ agreement involving a Turkish company, the parties should confirm:

• The correct company type;
• The identity and authority of every signatory;
• Whether the company will become a party;
• Which provisions should also appear in the articles;
• Whether share transfer restrictions comply with mandatory law;
• Whether future transferees must sign an accession deed;
• Whether option and valuation procedures are workable;
• Whether drag-along and tag-along clauses contain complete procedures;
• Whether reserved matters respect mandatory organ powers;
• Whether board nominees remain subject to statutory duties;
• Whether the deadlock mechanism is balanced;
• Which disputes are arbitrable;
• Which claims must remain before Turkish courts;
• Whether related contracts contain compatible arbitration clauses;
• Whether multiparty joinder and consolidation are addressed;
• Whether urgent interim measures may be required;
• Whether third-party or registry action will be necessary;
• Where the parties’ assets are located;
• Whether an eventual award will be enforceable.

Frequently Asked Questions

Are shareholders’ agreements valid under Turkish law?

Yes. Shareholders may regulate their contractual relationship within the principle of freedom of contract, provided that the agreement does not violate mandatory law, morality, public policy or statutory corporate rules.

Does a shareholders’ agreement automatically bind the company?

No. The company is not ordinarily bound unless it has validly become a party. Even when it is a party, it cannot perform obligations contrary to mandatory Turkish company law.

Can shareholder disputes be resolved by arbitration?

Many contractual shareholder disputes, including payment, indemnity, transfer, valuation, voting and confidentiality claims, may be arbitrated. Claims affecting the company’s legal status, all shareholders or official registries require separate arbitrability analysis.

Can an arbitrator annul a general assembly resolution?

This presents a significant risk under Turkish law. Statutory annulment proceedings are filed before the Commercial Court of First Instance at the company’s registered seat, and a final judgment binds all shareholders. The safer approach is to reserve such claims for the competent court.

Can an arbitral tribunal dissolve a Turkish company?

A contractual buy-out or exit mechanism may be arbitrated. A statutory action for just-cause dissolution under Article 531 is assigned to the commercial court and affects the company’s legal status, making direct arbitral dissolution highly problematic.

Are drag-along and tag-along rights enforceable?

They may create valid contractual obligations if drafted clearly. Their implementation must still comply with share transfer formalities, company approvals and rights of persons that did not consent to the agreement.

Can an arbitral tribunal compel a share transfer?

The tribunal may potentially order a signatory to perform contractual transfer obligations. The legal effectiveness of the transfer may still depend on the company type, required approvals, formal documents and registration procedures.

Should the company sign the arbitration clause?

Company participation may be useful, particularly where company obligations and information are involved. It does not remove arbitrability restrictions or permit the parties to override mandatory corporate provisions.

Can future shareholders be bound automatically?

A transferee should ordinarily sign a deed of adherence or another written accession document. Ownership of shares alone should not be assumed to establish consent to every provision of a separate shareholders’ agreement.

Can corporate arbitration be conducted in English?

Yes. The parties may select English as the arbitration language, while Turkish translations may be required for related Turkish court or registry proceedings.

Can the parties use ISTAC?

Yes. The parties may agree that disputes will be resolved under the ISTAC Arbitration Rules and may specify the seat, language, number of arbitrators and governing law.

Can a shareholder seek a court injunction despite an arbitration clause?

Yes. Applying to a competent court for an interim injunction or attachment does not itself violate the arbitration agreement under the International Arbitration Law.

Conclusion

Shareholders’ agreements provide an essential contractual framework for investments and joint ventures involving Turkish companies.

They allow shareholders to regulate management, voting, financing, share transfers, minority protection, confidentiality, deadlock and exit in substantially greater detail than is ordinarily practical within the registered articles of association.

However, a shareholders’ agreement remains subject to mandatory Turkish company law.

Contractual provisions cannot eliminate non-delegable powers of corporate organs, override capital-protection rules, bind persons that did not consent or create direct registry effects where statutory procedures are required.

Corporate arbitration is particularly effective for private contractual disputes involving share transfers, options, valuation, voting commitments, indemnities, confidentiality and breach of exit provisions.

Greater caution is required where the requested remedy would annul a general assembly resolution, dissolve the company, alter an official registry, affect creditors or bind all shareholders. These claims may fall outside the parties’ free disposition or involve statutory court procedures with effects extending beyond the arbitration agreement.

The most effective structure combines careful corporate drafting with a detailed arbitration clause.

The shareholders’ agreement, articles of association, share purchase agreement, investment agreement, guarantees and accession documents should contain coordinated provisions. All relevant parties should consent expressly, and contractual remedies should be supported by practical implementation mechanisms.

The arbitration clause should be broad enough to cover connected contractual claims but should include a carefully drafted carve-out for non-arbitrable corporate and registry matters.

For international investments, the parties should also select the seat, institution, language, tribunal structure and governing law after considering where an eventual award may need to be enforced.

A shareholders’ agreement should therefore not be treated merely as a commercial list of rights. It must be designed as an integrated contractual, corporate and dispute-resolution system capable of operating both during the investment and when the relationship breaks down.

Legal Disclaimer: This article is provided for general informational purposes only and does not constitute legal advice.
