Winning a lawsuit is not the same thing as collecting the money.

A creditor may have a signed contract, unpaid invoices, written acknowledgements of debt and a commercially strong claim. Yet none of those documents will matter if the debtor spends the next two years transferring every valuable asset out of reach.

The warning signs are familiar.

A debtor who previously held substantial cash suddenly begins emptying bank accounts.

Money is transferred to another company controlled by the debtor.

Properties are sold.

Vehicles are transferred to relatives.

Customers are instructed to make future payments into a different company’s account.

Cash withdrawals increase.

The debtor stops paying ordinary creditors while continuing to transfer funds to related parties.

By the time the creditor obtains a final judgment, the defendant may legally still owe the money but own virtually nothing.

Turkish enforcement law provides a powerful remedy for precisely this collection risk:

precautionary attachment — ihtiyati haciz.

Under Articles 257 and following of the Turkish Enforcement and Bankruptcy Law (“İİK”), a creditor can, under the statutory conditions, obtain a court order provisionally attaching the debtor’s assets before the merits dispute has been finally determined.

For a creditor who discovers that bank accounts are being emptied, the correct strategy is often not:

“File the case and wait for judgment.”

It is:

“Can we secure the assets before they disappear?”

1. What Is Precautionary Attachment?

Precautionary attachment is a temporary enforcement-security mechanism designed for monetary claims.

It allows qualifying assets of the debtor to be provisionally attached so that they remain available if the creditor later establishes and enforces the underlying claim.

Article 257 İİK expressly covers:

• movable property;
• immovable property;
• receivables held by third parties;
• other attachable rights.

Therefore, a debtor’s receivable against a bank arising from money standing to the debtor’s credit may be targeted within the enforcement framework.

The remedy is especially important because the court can act before the creditor obtains a final judgment.

2. The Most Important Rule: If the Debt Is Already Due, You Do Not Necessarily Have to Prove Asset Flight

This is one of the most misunderstood aspects of Turkish precautionary attachment law.

Article 257/1 provides that a creditor holding an:

unsecured and due monetary claim

may request precautionary attachment of the debtor’s assets and rights.

This means that where the claim:

1. is a monetary claim;
2. is already due; and
3. is not secured by a pledge or other qualifying security,

the creditor does not have to prove, as a separate statutory condition, that the debtor is currently fleeing Turkey or hiding property.

This distinction is extremely important.

Suppose:

• goods were delivered;
• EUR 300,000 became due on 1 July;
• the purchaser failed to pay;
• the debt is unsecured.

The creditor may potentially satisfy Article 257/1 even before proving that the debtor is stripping assets.

Evidence that the debtor is emptying its accounts nevertheless remains commercially and procedurally important because it demonstrates why immediate intervention is necessary and may support a request for the court to act without first warning the debtor.

3. Asset Concealment Becomes Legally Critical Where the Debt Is Not Yet Due

Article 257/2 regulates a different situation:

the debt has not yet matured.

Precautionary attachment for an unmatured debt is exceptional.

The statute permits it particularly where:

• the debtor has no fixed place of residence; or
• the debtor, in order to escape its obligations, prepares to hide or remove assets, prepares to flee or flees, or carries out fraudulent transactions infringing the creditor’s rights for that purpose.

This is where evidence that bank accounts are being emptied becomes potentially decisive.

Consider the following scenario.

A debtor owes TRY 20 million under a contract.

Payment is contractually due in three months.

The creditor learns that the debtor has:

• transferred almost all cash to another company owned by the same shareholders;
• begun selling real estate;
• moved vehicles to relatives;
• ceased ordinary commercial operations.

The debt is technically not due.

But the creditor may argue that Article 257/2 applies because the debtor is deliberately removing assets to escape future payment.

If precautionary attachment is ordered in these circumstances, the statute also provides for the debt to become due against the debtor as a consequence of the attachment.

4. Emptying a Bank Account Is Not Enough by Itself — Context Matters

A company transferring money is not automatically hiding assets.

Businesses legitimately move money every day.

A TRY 10 million transfer may represent:

• payment to a supplier;
• tax;
• loan repayment;
• payroll;
• investment;
• inventory acquisition;
• legitimate group-company financing.

Therefore, the creditor should not merely argue:

“Money left the bank account.”

The stronger argument is:

“The debtor is systematically reducing attachable assets without a credible commercial explanation in circumstances showing an intention to prevent collection.”

The court should be given the entire factual picture.

5. What Evidence Shows That a Debtor Is Actually Preparing to Defeat Collection?

Where asset flight is relevant, several forms of evidence can become powerful.

Transfers to related companies

Suppose Debtor A.Ş. transfers most of its cash to another company owned by the same shareholder after receiving a demand for payment.

That relationship should be documented.

Trade registry records can help establish common:

• shareholders;
• managers;
• addresses;
• directors.

Transfers to relatives

Property or vehicles transferred to:

• a spouse;
• parent;
• sibling;
• child

shortly after the debt dispute begins can strengthen the factual picture.

Kinship alone is not proof of fraud.

Timing, price and economic reality matter.

Disposal of multiple assets within a short period

One ordinary property sale may prove little.

The simultaneous sale of:

• two apartments;
• several vehicles;
• machinery;
• company shares

immediately after receipt of a payment demand looks very different.

Statements by the debtor

Messages can be highly important.

For example:

“You will not be able to collect anything from me.”

or

“By the time your lawsuit ends, there will be nothing left in the company.”

Such statements can materially strengthen an application when lawfully obtained and submitted.

Changes in payment channels

Suppose customers who historically paid Debtor A.Ş. are suddenly told to pay another related company.

This can show an attempt to redirect future receivables away from the debtor.

Previous unsuccessful enforcement

Existing enforcement files showing that the debtor has no attachable assets may also support the creditor’s overall position.

6. You Do Not Need to Prove the Entire Lawsuit at the Precautionary Attachment Stage

Article 258 is particularly important.

The creditor must submit evidence sufficient to persuade the court regarding:

• the existence of the claim; and
• where required, the grounds supporting precautionary attachment.

The statute does not require the underlying debt to be finally proven as though the court were already deciding the merits.

Turkish appellate practice describes this as an approximate proof — yaklaşık ispat — standard.

The creditor must make the existence of the claim sufficiently probable.

For example, Istanbul Regional Court of Appeal decisions recognise that the creditor is not required at the precautionary attachment stage to prove the debt finally and conclusively under the full evidentiary standard applicable to the merits.

This is precisely why the remedy can function quickly.

7. What Documents Make a Strong Application?

A strong precautionary attachment file should normally contain much more than an invoice.

For a commercial debt, useful evidence may include:

• signed contract;
• purchase order;
• delivery documents;
• invoices;
• account reconciliation;
• e-mail correspondence;
• WhatsApp correspondence;
• partial payments;
• written acknowledgment of debt;
• payment promises;
• bank records;
• notices of default;
• customs and shipment records;
• service acceptance documents.

One reported Istanbul Regional Court of Appeal case concerned an application supported by customs declarations, e-mails, WhatsApp correspondence, contractual documentation and invoices. The lower court considered those materials sufficient to establish the claim approximately and granted precautionary attachment subject to security.

The practical lesson is simple:

Do not ask the court to freeze millions of lira based only on your own allegation.

Construct the contractual chain from performance to non-payment.

8. A Signed Account Reconciliation Can Be Extremely Powerful

Commercial disputes frequently contain a document stating that the parties reconciled their accounts as of a particular date.

For example:

“Balance payable by Buyer to Seller: TRY 4,850,000.”

A document of this nature can significantly strengthen approximate proof.

A 2026 Istanbul Regional Court of Appeal decision emphasised that Article 258 does not require final proof and considered documents including a written account reconciliation highly relevant when assessing whether the underlying monetary claim had been sufficiently established at the interim stage.

For this reason, before litigation begins, commercial creditors should preserve:

• reconciliations;
• debt confirmations;
• restructuring protocols;
• payment schedules.

They may later become the foundation of an urgent attachment application.

9. Can the Court Grant the Order Without Hearing the Debtor?

Yes.

Article 258 expressly gives the court discretion to decide whether to hear both parties before ruling.

This is one of the features that makes precautionary attachment effective.

Imagine that the debtor still has TRY 10 million in a bank account.

If the court first sends the debtor:

“The creditor wants to freeze your bank account. Please submit your defence.”

the account may be empty before the hearing takes place.

Accordingly, where there is a credible dissipation risk, the creditor should explain specifically why prior notice would frustrate the purpose of the protection.

The application should not merely request an ex parte decision.

It should explain:

Why would giving advance warning create a real collection risk?

10. The Court Should Be Told That Speed Is Part of the Remedy

A well-drafted petition should create a chronological narrative.

For example:

3 August: debt acknowledged.

8 August: creditor sends payment demand.

10 August: debtor transfers TRY 5 million to affiliated company.

12 August: debtor sells vehicle fleet.

14 August: debtor informs customer that future payments should be made to another company.

16 August: debtor states that it will not pay the creditor.

This chronology is much more persuasive than repeatedly stating:

“There is a risk of asset concealment.”

Courts need facts.

Not adjectives.

11. Which Court Grants Precautionary Attachment?

Article 258 refers to the court determined pursuant to the jurisdiction principles of Article 50 İİK.

The precise competent court therefore depends on matters including:

• the nature of the underlying dispute;
• the debtor;
• contractual jurisdiction rules;
• the relevant territorial connection;
• special jurisdiction provisions.

Where the underlying claim is a commercial dispute between businesses, the Commercial Court of First Instance — Asliye Ticaret Mahkemesi — will commonly be the relevant court, subject to the specific circumstances.

Jurisdiction should be checked before filing.

An urgent application can lose valuable time if submitted to the wrong court.

12. The Claim Must Normally Be Unsecured

Article 257/1 applies to monetary claims not secured by pledge.

This reflects a fundamental enforcement principle.

If the creditor already has adequate collateral specifically securing the debt, precautionary attachment ordinarily should not be used to provide unnecessary additional security beyond the statutory framework.

The precise scope and adequacy of existing security should therefore be investigated.

13. The Creditor Usually Has to Provide Security

Precautionary attachment is powerful.

It can freeze property before the creditor has finally won.

For that reason, Article 259 ordinarily requires the creditor to provide security for potential losses suffered by the debtor or third parties if the attachment later proves unjustified.

There are important exceptions.

If the claim is based on a court judgment, security is not required.

If it is based on a document legally treated as having the nature of a judgment, the court has discretion regarding whether security is necessary.

In ordinary commercial claims, courts commonly order security as a percentage of the claim.

For example, reported cases include precautionary attachment orders issued subject to 15% security, although this should not be misunderstood as a universal statutory percentage. The amount is determined judicially according to the circumstances.

14. A Creditor Should Budget for Security Before Filing

This is an important practical point.

Suppose the claim is TRY 100 million.

If the court requires substantial security, the creditor needs to be able to provide it quickly.

A company that obtains a favourable attachment decision but cannot satisfy the required security may lose the opportunity to implement the order while assets continue to disappear.

Before filing, counsel should therefore discuss:

• likely security;
• form of security;
• availability of cash;
• bank guarantee options.

Urgent litigation should not begin without considering the practical ability to implement the result.

15. What Can Be Frozen?

The attachment should be directed toward assets sufficient to secure the claim.

Potential targets can include:

Bank accounts

One of the most important targets where the debtor is moving cash.

Receivables from third parties

For many companies, receivables from customers may be more valuable than bank balances.

Real estate

Land, offices, apartments, commercial properties.

Vehicles

Subject to ordinary attachment rules.

Company shares

Where legally attachable.

Other property rights

Provided that the relevant right is legally subject to attachment.

Article 257 expressly allows attachment not only of property physically held by the debtor but also qualifying receivables and rights held through third parties.

16. Do Not Request an Unlimited Freeze

The objective of precautionary attachment is to secure the debt.

It is not to punish or economically destroy the debtor.

The application should therefore seek attachment up to the amount necessary to secure the claim, including legally relevant accessories where appropriate.

A proportional request is also more defensible if the debtor later challenges the order.

17. How Does the Bank Account Actually Become Frozen?

Obtaining the court order is only the first stage.

The precautionary attachment order must then be implemented through the enforcement office.

This procedural distinction is critical.

The court authorises the precautionary attachment.

The enforcement machinery implements it against the debtor’s attachable assets and third-party rights.

For bank assets, the enforcement process is directed toward the debtor’s rights and receivables held by the relevant banking institutions.

If the debtor has already emptied one bank, counsel should not assume that this ends the investigation.

There may be:

• accounts at other banks;
• new incoming payments;
• customer receivables;
• other financial rights.

18. The 10-Day Rule Can Destroy an Otherwise Perfect Order

This is one of the most dangerous procedural traps.

Article 261 provides that the creditor must request implementation of the precautionary attachment from an enforcement office within the judicial district of the court within ten days from the date the court gives the decision.

If the creditor fails to do so:

the precautionary attachment order automatically lapses.

The period runs from the date of the decision, not from when the creditor eventually decides to use it.

Appellate practice has applied this rule strictly and has treated precautionary attachment as automatically extinguished where timely implementation was not requested.

Accordingly, counsel should treat the ten-day period as an emergency deadline.

19. Do Not Wait for the Debtor to Be Served Before Implementing the Order

A creditor sometimes obtains the decision and thinks:

“We will wait for formal service and then execute it.”

That can be a serious mistake.

Article 261 links the implementation period to the date the decision is issued.

The entire commercial purpose of the remedy is rapid execution.

When accounts are being emptied, every day can matter.

20. The 7-Day “Completion” Rules Are Equally Important

Another deadline follows implementation.

Where precautionary attachment was obtained before the main lawsuit or enforcement proceeding, Article 264 requires the creditor, depending on the circumstances, to take the prescribed step to continue the underlying enforcement process within a strict seven-day period following attachment or relevant service.

If the debtor objects to the enforcement proceeding, Article 264 also contains strict deadlines for taking the necessary procedural action to overcome that objection.

Failure to follow the completion rules can cause the precautionary attachment to become ineffective.

This creates an important practical principle:

Never obtain an ihtiyati haciz decision without simultaneously planning the main claim or enforcement proceeding.

The precautionary attachment and the merits strategy must be designed together.

21. Mandatory Mediation Must Be Planned Together With Article 264 Deadlines

Many Turkish commercial monetary disputes are subject to mandatory mediation before a merits lawsuit can proceed.

This creates a procedural issue that must be considered before the precautionary attachment is implemented.

Counsel should not assume that initiating mediation automatically cures every deadline arising under Article 264.

The sequence between:

• precautionary attachment;
• enforcement;
• objection;
• mediation;
• merits proceedings

must be designed according to the specific claim.

The key practical lesson is:

Do not first obtain the attachment and only afterwards ask how it will be maintained.

22. The Debtor Can Object — But Only on Specified Grounds

A debtor who was not heard before the order may challenge the precautionary attachment.

Article 265 permits objections based on grounds including:

• the reasons supporting the precautionary attachment;
• the court’s jurisdiction;
• the security.

Where the attachment was carried out in the debtor’s presence, the seven-day objection period runs from implementation; otherwise, it runs from service of the attachment record.

Third parties whose interests are affected can also object within the statutory period following learning of the attachment.

The applicant should therefore prepare the original file as though the debtor will challenge it immediately.

23. Appeal Does Not Automatically Stop Implementation

Article 265 provides that the decision rendered on an objection may be taken to the regional appellate court.

The regional appellate court examines the matter with priority, and its decision is final.

Importantly, an appellate application does not itself stay implementation of the precautionary attachment.

This reinforces the protective character of the remedy.

24. Can the Debtor Replace the Attachment With Security?

Turkish law also allows the debtor, subject to the statutory conditions, to seek release of the attached assets by providing acceptable security.

Article 266 permits mechanisms such as:

• money;
• qualifying pledge;
• acceptable securities;
• immovable security;
• reliable bank guarantee,

subject to the court’s assessment and statutory requirements.

From the creditor’s perspective, this is not necessarily a bad outcome.

The commercial purpose is security for collection.

If an uncertain bank account is replaced by a robust bank guarantee securing the debt, the creditor may actually be placed in a better enforcement position.

25. Example: Debtor Empties TRY 25 Million From Its Accounts

Assume the following.

Seller A.Ş. supplies machinery to Buyer Ltd.

Purchase price:

TRY 18 million.

The machinery is delivered and accepted.

Payment becomes due on 1 August.

Buyer fails to pay.

On 5 August, Buyer confirms by e-mail:

“We acknowledge the balance and will arrange payment.”

Payment does not arrive.

The creditor then discovers:

• Buyer previously maintained approximately TRY 25 million liquidity;
• TRY 12 million was transferred to another company owned by Buyer’s majority shareholder;
• two vehicles were sold;
• customers were instructed to pay new invoices into the affiliated company’s bank account;
• management stops answering payment demands.

Is the claim appropriate for precautionary attachment?

Potentially, yes.

The claim is:

• monetary;
• due;
• apparently unsecured.

Accordingly, Article 257/1 may provide the statutory basis without the creditor having to establish asset concealment as an additional condition.

Nevertheless, the suspicious transfers strongly demonstrate why immediate protection is commercially necessary.

What should be submitted?

The creditor could present:

• contract;
• delivery documentation;
• invoices;
• written acknowledgment;
• payment demand;
• evidence concerning the affiliated company;
• evidence of suspicious asset transfers lawfully available.

What should be requested?

Precautionary attachment up to the amount necessary to secure the debt over the debtor’s:

• bank receivables;
• movable property;
• real estate;
• customer receivables;
• other attachable rights.

The petition should also explain why hearing the debtor first could defeat the purpose of the application.

26. Example: The Debt Is Not Due for Another Three Months

Now change one fact.

The TRY 18 million debt matures on 1 November.

It is currently August.

Buyer nevertheless begins transferring everything to a new affiliated company and has openly stated that creditors will not be able to collect from it.

Article 257/1 cannot simply be applied on the basis of a due debt because the debt has not matured.

The creditor must instead establish the exceptional conditions of Article 257/2.

This is where evidence of:

• disappearing balances;
• related-party transfers;
• asset sales;
• fraudulent restructuring;
• statements showing an intention to defeat collection

becomes central.

The petition should connect the evidence directly to the statutory requirement.

27. Example: There Is Only a Fear That the Debtor Might Hide Assets

Suppose the creditor says:

“The debtor has not transferred anything, but I am worried it might do so.”

That statement is much weaker.

Especially where Article 257/2 must be relied upon, speculative concern is not enough.

The creditor must provide facts capable of persuading the court.

Appellate decisions emphasise that the claimant must submit evidence capable of creating judicial conviction regarding both the claim and, where required, the particular attachment grounds.

The petition should therefore distinguish between:

possible future risk

and

observable asset-dissipation conduct.

28. Do Not Confuse Precautionary Attachment With Precautionary Injunction

Turkish procedural law distinguishes:

ihtiyati haciz
from
ihtiyati tedbir.

For ordinary unsecured monetary claims, precautionary attachment is the specific protective mechanism established by İİK Articles 257 and following.

A creditor seeking to secure payment should therefore not mechanically request a generic injunction over the debtor’s entire property.

The correct protective institution must be selected according to the nature of the claim.

This classification matters because the statutory conditions, objections, security and enforcement mechanisms are different.

29. What If the Money Has Already Been Transferred to the Debtor’s Brother or Another Company?

Precautionary attachment against the debtor does not automatically convert another person’s property into the debtor’s property.

Suppose Debtor A transfers TRY 10 million to Company B.

If Company B genuinely owns the funds when proceedings begin, an attachment against A cannot simply be used as though B’s bank balance still belonged to A.

Different legal remedies may then need to be considered, including depending on the facts:

• recovery of a receivable A has against B;
• fraudulent-transfer litigation under İİK Articles 277 and following;
• simulation under Article 19 of the Turkish Code of Obligations;
• claims arising from unjust enrichment or invalid transactions;
• director liability where company assets were diverted.

This is why acting before the transfer is completed can be dramatically easier than attempting to unwind it afterwards.

30. Follow the Debtor’s Receivables, Not Only the Current Bank Balance

A debtor may deliberately keep bank balances close to zero.

That does not necessarily mean the debtor has no value.

Suppose Debtor A.Ş. has:

TRY 50,000 in the bank,

but is owed:

TRY 8 million by Customer X,

TRY 4 million by Customer Y,

and TRY 3 million by Customer Z.

Those receivables may be much more important than the bank account.

Article 257 permits qualifying third-party receivables and rights to be provisionally attached.

A good collection lawyer therefore asks not only:

“Which bank does the debtor use?”

but:

“Who owes the debtor money?”

31. The Most Effective Application Is Built Like an Asset-Tracing Report

For a high-value claim, the petition can be structured around three categories.

A. The Debt

Prove approximately:

• contractual relationship;
• performance;
• amount;
• maturity;
• absence of security.

B. The Dissipation Risk

Where legally relevant or strategically useful, show:

• asset transfers;
• related-party relationships;
• disappearing cash;
• unusual sales;
• redirection of customer payments;
• debtor communications.

C. The Target Assets

Identify, where possible:

• banks;
• real estate;
• vehicles;
• customer receivables;
• company interests;
• other attachable rights.

This turns the application from a generic legal request into an actual collection plan.

32. A Practical Timeline

Where the creditor learns on Monday morning that accounts are being emptied, the legal strategy should operate on a compressed timeline.

Immediately

Preserve:

• contract;
• invoices;
• correspondence;
• acknowledgements;
• transfer evidence;
• trade registry records.

Before filing

Determine:

• whether debt is due;
• whether secured;
• competent court;
• amount to be secured;
• likely security requirement;
• potential asset targets.

With the application

Request:

• attachment for a precisely stated amount;
• appropriate coverage of bank receivables and other assets;
• where justified, determination without first hearing the debtor.

After the order

Immediately arrange:

• security;
• enforcement-office implementation.

Within statutory deadlines

Observe:

• Article 261’s ten-day implementation period;
• Article 264 completion requirements.

A creditor can win the emergency application and still lose the protection through procedural inactivity.

33. The Five Biggest Mistakes Creditors Make

Mistake 1: Waiting for the lawsuit to finish

By the time judgment arrives, the debtor may have no assets.

Mistake 2: Believing mal kaçırma must always be proved

For an unsecured due monetary claim under Article 257/1, asset concealment is not an additional statutory requirement.

Mistake 3: Filing only invoices

Approximate proof is easier than final proof, but the application should still contain a credible evidentiary chain.

Mistake 4: Obtaining the order but missing the 10-day enforcement deadline

Article 261 causes the decision to lapse automatically if implementation is not timely requested.

Mistake 5: Forgetting the completion procedure

Precautionary attachment obtained before the underlying proceeding must be followed by the required Article 264 steps within strict periods.

34. Final Takeaway

When a debtor starts emptying bank accounts, the creditor should not automatically accept that collection must wait until the end of a multi-year lawsuit.

Turkish law provides a much faster protective mechanism.

Under Article 257/1 İİK, the creditor of an unsecured, due monetary claim can seek precautionary attachment of the debtor’s attachable property, receivables and rights. Crucially, where the debt is already due, proving a separate asset-concealment condition is not ordinarily required by the statutory text.

Where the debt is not yet due, however, the statutory threshold becomes significantly more demanding. Evidence that the debtor is hiding or transferring assets, preparing to flee or engaging in fraudulent transactions designed to defeat the creditor can bring Article 257/2 into operation.

Article 258 allows the court to act on an approximate evidentiary standard and gives it discretion to decide the application without first hearing the debtor — an essential feature where advance warning could result in the remaining funds disappearing.

But obtaining the decision is only the beginning.

The creditor must be prepared to:

provide security,

implement the order immediately,

comply with the ten-day period under Article 261,

and

complete the necessary underlying proceedings within the strict Article 264 framework.

For that reason, when a client says:

“The debtor had millions in the bank last week and is transferring everything out today,”

the first question should not be:

“When can we file the main lawsuit?”

It should be:

“What evidence do we already have, what can still be attached, and can we obtain an ihtiyati haciz before the next transfer leaves the account?”

In serious debt recovery cases, timing often determines whether a judgment becomes money.

Once the bank account is empty, litigation becomes harder. Precautionary attachment exists to act before that happens.
