Precautionary Attachment for an Unpaid Foreign Invoice in Turkey: Evidence, Security and Procedure – 2026 Updated Guide

Foreign Invoice Attachment Turkey | Evidence and Procedure

Learn how foreign companies can request precautionary attachment for an unpaid invoice in Turkey, including evidence, security, court procedure and enforcement.

A foreign company may need to secure its unpaid invoice before a Turkish debtor transfers money, sells property or becomes insolvent. In Turkey, a court-ordered precautionary attachment, also commonly called a provisional attachment, may protect the creditor before a final judgment.

The measure is not automatic. The foreign creditor must present evidence of the invoice debt and show why immediate protection is necessary.

This 2026 updated guide explains the evidence, security and procedure for obtaining precautionary attachment for an unpaid foreign invoice in Turkey.

What Is a Precautionary Attachment?

A precautionary attachment is a temporary legal measure that restricts a debtor’s ability to dispose of certain assets while the creditor pursues enforcement or litigation.

The attachment may concern bank accounts, real estate, vehicles, shares, inventory or receivables owed to the Turkish debtor by third parties.

It does not transfer ownership to the foreign creditor and does not finally establish that the invoice is valid. The creditor must continue with the underlying enforcement, commercial lawsuit or other required procedure.

Can Attachment Be Requested Before a Judgment?

A foreign company may request precautionary attachment before obtaining a final judgment if the legal requirements are satisfied.

The creditor generally needs to show that the monetary claim is due, supported by credible evidence and at risk of becoming difficult to collect. If the invoice is not yet due, this remedy may be limited, although other urgent measures may sometimes be considered.

The court evaluates the claim, the debtor’s conduct, the risk of asset dissipation and the proportionality of the requested protection.

What Evidence Is Needed?

The application should normally include the unpaid invoice and evidence connecting it to the underlying transaction.

Useful documents may include the contract, purchase order, delivery note, transport record, customs document, acceptance certificate, service report, account statement and payment demand.

Emails, WhatsApp messages, partial payments and acknowledgments of debt may also support the claim. Evidence that the debtor is transferring assets, closing operations or paying related companies may support the urgency requirement.

Is an Invoice Alone Enough?

An invoice may support an attachment application, but it may not be sufficient if the Turkish debtor denies the order, delivery, price or performance.

The stronger approach is to submit a complete evidence file showing the commercial relationship, delivery or performance, due date and amount outstanding.

If the debtor claims that the goods were defective or the services were incomplete, the foreign company should preserve technical and acceptance evidence before filing.

Is Security Required?

The court may require the foreign creditor to provide security before implementing the precautionary attachment.

Security is intended to protect the debtor against potential damage if the attachment is later found to be unjustified. The amount and form depend on the court’s assessment, the strength of the evidence, the value of the claim and the possible harm.

A foreign company may also face separate procedural security issues as a foreign claimant, subject to applicable treaties and reciprocity rules.

Which Court Should Receive the Application?

The competent court depends on the debtor’s location, the nature of the commercial claim, the contract and any jurisdiction or arbitration clause.

The foreign company should review whether the claim falls within commercial court jurisdiction and whether a Turkish court has authority to grant interim protection.

An application filed before the wrong court may cause delay at a critical stage, particularly if the debtor is preparing to transfer assets.

What Happens After the Court Grants the Attachment?

After the court grants the order and any required security is provided, the attachment must be implemented through the appropriate enforcement procedure.

The relevant bank, land registry or other institution may be notified. The debtor’s ability to dispose of the attached asset may then be restricted.

The foreign creditor must take the next procedural step within the applicable period. The attachment does not replace the main debt claim.

Can Bank Accounts and Real Estate Be Attached?

Depending on the order and available information, the creditor may request attachment of bank accounts, real estate, vehicles, shares, inventory and third-party receivables.

The creditor should identify the debtor accurately and provide available information about the property or financial institution. An attachment against an empty account will not produce immediate payment, so a broader asset strategy may be necessary.

Real estate records should be examined for existing mortgages, liens and other priority rights.

What If the Debtor Objects?

The Turkish debtor may challenge the precautionary attachment, request its removal or argue that the invoice is disputed, not due or insufficiently supported.

The debtor may also claim that the attachment is excessive or that the creditor failed to satisfy procedural requirements. If the attachment was unjustified and caused damage, the creditor may face a compensation claim.

The foreign company should therefore request only the amount and assets necessary to secure the claim and provide accurate evidence.

How Is the Main Debt Collected?

After attachment, the foreign creditor may need to begin or continue enforcement proceedings or file a commercial lawsuit.

If the debtor objects to enforcement, the creditor may need to challenge the objection or prove the debt through litigation. For certain commercial monetary claims, pre-litigation mediation may be required before filing a commercial lawsuit.

If the contract contains an arbitration clause, the creditor should assess whether arbitration and Turkish interim protection can proceed together.

Can the Claim Be in a Foreign Currency?

The invoice may be denominated in a foreign currency if the contract and applicable rules support that arrangement.

The application should state the principal, currency, due date, interest and any exchange-rate calculation clearly. The creditor should use a consistent calculation in the demand, attachment application and main proceeding.

Bank charges, partial payments and currency conversion may need to be examined by a financial expert.

What If the Debtor Has Already Transferred Its Assets?

If the debtor already moved money or property, the foreign creditor may investigate the recipient, the relationship between the parties, the transaction price and the commercial purpose.

Transfers to shareholders, directors or related companies may support a fraudulent-transfer or asset-concealment claim if the legal requirements are satisfied.

The creditor may also seek attachment of other assets and receivables while pursuing recovery of the transferred value.

What Evidence Matters in 2026?

In 2026, electronic invoices, online bank confirmations, accounting software, cloud records, corporate emails and business messages may be decisive.

The foreign company should preserve original files, complete communication chains, delivery evidence and proof of asset transfers. Screenshots alone may be challenged.

Digital evidence should be collected lawfully and stored in a form that can be reviewed by the court or a financial expert.

Can a Foreign Company Apply from Abroad?

A foreign company does not always need to travel to Turkey. A Turkish lawyer may apply under a power of attorney issued before a Turkish consulate or a local notary.

Depending on the issuing country, legalization, apostille and official translation may be required. Foreign corporate documents and invoice evidence may also need certification and translation.
