1. Start with a route map, not a list of assets

An effective file begins with a transaction chronology and a legal route map. The chronology should identify the contracting parties, representations, transfer instructions, payment chain, account details, goods or services promised, performance, complaints, acknowledgments and the first reliable indication that the expected transaction did not occur. Each statement should be linked to its original record. The route map then asks what relief is legally available on those facts: determination of evidence, an interim injunction, provisional attachment, enforcement, an avoidance action, a criminal complaint, or a combination coordinated without confusing their effects.

This classification matters because the word “freeze” hides substantial differences. A civil interim injunction under the Code of Civil Procedure concerns the subject of the dispute and addresses a risk that change or delay will make the right difficult to obtain or cause serious harm. Provisional attachment under the Enforcement and Bankruptcy Law protects a qualifying money claim and reaches specified property and rights. Ordinary or judgment-based enforcement pursues satisfaction after its own procedural prerequisites. A criminal seizure protects evidence or property potentially connected with confiscation. Confiscation follows criminal-law requirements and cannot be promised merely because seizure occurred.

Build an asset hypothesis rather than a public allegation. Record the source and date of every lead and distinguish ownership from control, use or appearance. Corporate affiliation does not establish that one company owns another company’s property. A photograph, profile or social post may justify a lawful inquiry but does not prove title, fraud or availability for enforcement. Social-media material is a lead, not proof.

The claimant’s objective also needs precision. Preserving a specific disputed asset, securing a matured monetary claim, obtaining documents, preventing destruction of evidence, participating as an injured party and enforcing a final entitlement are separate objectives. Selecting a measure because it sounds forceful can waste time and expose the applicant to security or damages consequences. The application must instead connect a recognised legal interest to the correct actor, threshold and requested order.

2. Lawful civil evidence and document production

Civil proof in Türkiye is directed to disputed facts that can affect the outcome. The party relying on a fact generally carries the burden for the favourable legal consequence it seeks, subject to special burden rules and statutory presumptions. The court decides admissibility and cannot use unlawfully obtained evidence to prove a fact. That makes the acquisition method part of the evidence plan. Unauthorised access to email, accounts, devices or private systems can harm the case and create separate exposure. Counsel should identify lawful preservation and production routes before copying or requesting material.

The Code of Civil Procedure treats written, visual, audio and electronic information carriers as potential documents. In practice, the useful record is usually more than a screenshot. Preserve the native email with headers, the full message chain, bank records obtained through a lawful channel, platform exports, signed contracts, invoices, delivery or service records, device or server metadata and the provenance of each copy. Hashes can help show that a collected file was not altered after acquisition, but a hash does not prove authorship, truth or lawful acquisition. Those questions remain separate.

A party must produce documents on which either side relies when those documents are in its possession. Electronic records should be submitted in a reviewable form required by the procedure. Where a continuously used record such as a commercial book is only partly relevant, certified copies of the relevant parts may be submitted. If a requested document is necessary and the statutory indicators of possession exist, the court can order production within a definite period. A party denying possession may face the statutory oath mechanism concerning possession, search and knowledge of location. Unexcused non-production or refusal of the oath can permit the court, according to the circumstances, to accept the opponent’s account of the document’s contents.

These provisions are tools for a defined dispute, not a licence for speculative discovery. A request should identify the material, the fact it bears on, the reason possession is attributed to the other party, and the form in which it can be examined. Separate requests may be needed for records held by banks, registries, service providers or public bodies. Foreign records also require attention to authenticity, translation, legalisation and the route by which they may be used in Turkish proceedings.

Where evidence risks disappearing or becoming materially harder to use, a party may seek determination of evidence. Inspection, expert examination, witness evidence or a similar step may be requested for a pending or future action when there is a legal interest in taking it promptly. Evidence preservation records a fact; it does not itself attach property, determine civil liability or decide a criminal allegation. The requested act and the threatened evidentiary loss should therefore be stated with care.

3. Civil interim injunctions protect the subject of the dispute

An interim injunction is a civil protective measure concerning the disputed right or property. It may be available where change in the existing situation would make acquisition of the right substantially difficult or impossible, or where delay creates a risk of serious harm. The applicant must clearly state the legal ground and form of the requested measure and approximately prove the justification on the merits. The court may order custody or deposit, require or prohibit an act, or choose another measure suited to removing the danger or preventing harm.

The measure should match the claim. If the dispute concerns ownership of identified shares or real estate, the requested restriction must be connected to that subject. If the underlying demand is simply payment of money, provisional attachment may be the more directly relevant security mechanism. Labelling an ordinary debt case as an ownership dispute does not change the legal threshold. The application should explain the asset, present status, threatened change, causal risk, urgency and why a narrower measure would be insufficient.

An injunction may be ordered without first hearing the opponent when immediate protection makes a prior hearing impracticable. That procedural possibility does not lower the substantive need for a coherent, candid evidentiary presentation. The applicant should disclose material facts that affect proportionality and should avoid presenting inference as established ownership. A court may require security for harm to the opponent and third parties if the applicant ultimately proves wrong, subject to the statutory evidence, circumstances and legal-aid exceptions.

Forum and timing follow the Civil Procedure Code. The competent court differs depending on whether the main action has already begun. An order before the action also carries follow-on obligations under the current statute. Because the official source package identifies conflicts between some amendment footnotes and body-rendered numeric periods, this guide gives no case-specific deadline. Counsel should read the current consolidated article, the order, service record and transition rules on the filing day.

An injunction does not resolve title, award damages, create a general investigative mandate or assure that value will remain sufficient. It is a temporary civil measure. Breach of an order, third-party rights, later security applications and the fate of the measure during the main proceedings require their own review. The order’s wording and the registry or custodian to which it must be communicated are operationally important.

4. Provisional attachment secures qualifying monetary claims

Provisional attachment under the Enforcement and Bankruptcy Law is designed for money claims. An unsecured creditor with a due monetary claim may request attachment of the debtor’s specified movable or immovable property, receivables and other rights, whether held by the debtor or a third party. For an unmatured claim, the remedy is narrower: the statute addresses the debtor’s lack of a fixed residence or specified conduct indicating flight, concealment or fraudulent evasion. When attachment is ordered on those grounds, acceleration has the limited statutory effect stated for that debtor.

The creditor applies to the competent court and must present evidence sufficient to persuade it about the claim and, where relevant, the special attachment ground. The court may decide whether to hear the parties. The evidentiary threshold is provisional, but the claim still needs a concrete basis: parties, amount, maturity, payment trail, contract or other source, and the facts said to create risk. Assertions that assets “might disappear” should not replace evidence of the statutory condition.

Security is a central part of the remedy. Unless the claim is judgment based or the court applies the document-based exception, the creditor must provide security and bears responsibility for harm to the debtor or third parties if the attachment proves unjustified. The order itself must contain the statutory particulars, including the parties, evidentiary and amount basis, reason, assets and security or liability information. A carefully limited request assists both proportionality and execution.

An order is only the beginning. The creditor must request execution from the competent enforcement office within the current statutory period or the order lapses. Execution uses the ordinary attachment rules, and execution complaints belong to the supervising enforcement court. The officer records the attached property and value and the office serves the record as required. Property may be retained or released against the security accepted under the relevant statutory route.

The procedure includes short follow-on duties after attachment, service, an objection to a payment order or a merits judgment. A debtor not heard before attachment and an affected third party have statutory objection routes. Review is confined to the stated grounds, and appeal does not suspend execution in the manner specified by the statute. Because triggers and current periods must be matched to the actual record, no case-specific deadline is supplied here.

Provisional attachment creates no general priority. Other attachments, pledges, public claims, third-party ownership and insolvency may control distribution. A valid order can preserve a procedural position while yielding little or no payment. It does not guarantee recovery.

5. Avoidance actions and final enforcement answer different questions

An asset transfer before or during the dispute raises at least three distinct issues. The first is whether the debtor ever owned the property. The second is whether a completed transfer can be challenged under the statutory avoidance regime. The third is how a successful claim or judgment can be enforced against value still legally reachable. These questions should not be collapsed into an allegation that every transfer involving a relative, affiliate or low price is automatically void.

The Enforcement and Bankruptcy Law gives standing for an avoidance action to the creditor holding the required insolvency certificate, the insolvency administration, or the listed creditors in the circumstances stated by the statute. Gifts and gratuitous dispositions within the current statutory lookback may be challenged under Article 278, including the categories treated as gifts subject to the law’s classifications and rebuttal rules. Article 280 concerns transactions by an insolvent debtor made to prejudice creditors when the counterparty knew or should have known that purpose from clear indications, together with the statute’s enforcement or bankruptcy condition.

The avoidance court uses the simplified procedure and has the discretion defined by the statute. It may grant provisional attachment within that proceeding, with security governed by the specific article. A successful judgment produces the enforcement and monetary-liability effects set out by law; it may also engage recourse and good-faith restitution issues for the affected third party. The transaction is not simply erased for every purpose, and liability should not be asserted beyond the judgment’s statutory effect.

Final enforcement remains subject to ownership, ranking and exemption rules. Registry entries, encumbrances and third-party claims must be examined. If a collective insolvency process appears, its current official decision should be reviewed before an individual step is chosen.

Civil damages may rest on contract, tort or unjust enrichment depending on the facts. A person causing loss through culpable unlawful conduct, or the qualifying intentional immoral conduct described by the Code of Obligations, must compensate under the statutory conditions. The injured person proves loss and fault; where exact loss cannot be established, the judge may estimate it from the ordinary course and measures taken. Unjust enrichment requires return where enrichment from another’s assets or labour lacks, loses or never obtains a valid cause. Limitation depends on the claim basis, knowledge, ultimate periods, possible longer criminal limitation and interruption events. It must be calculated from the file, never from this general guide.

6. Criminal preservation and seizure serve a public investigation

Criminal preservation and seizure are public-law measures. Under the Criminal Procedure Code, property useful as evidence or potentially subject to object or gain confiscation must be placed under preservation. If the possessor does not deliver it voluntarily, it may be seized. Its value must be determined when the relevant paragraph applies, and a person holding the described property or value must show and deliver it when lawfully requested.

Law-enforcement officers ordinarily act on a judge’s decision or on the specified written urgent authority. A seizure made without a prior judicial decision enters the statutory approval process and lapses if the required approval and decision do not occur in time. A person whose property or value is seized may ask the judge for a decision while the measure continues. The victim must be notified of the seizure operation without delay. These safeguards matter even in a serious investigation; urgency does not remove the legal source, authority or review requirements.

Article 128 has a more specific asset-seizure regime. It requires concrete evidence creating strong suspicion that the investigated offence occurred and that the specified assets were obtained from it. The authority-specific crime-value report and its timetable form part of the statutory architecture. Fraud under Criminal Code Articles 157 and 158 is within the catalogue, but catalogue inclusion alone does not establish the offence, the asset connection or the threshold. Article 128 seizure and appointment of an asset manager require a judge.

Execution differs by asset. A bank-account order is communicated immediately through the prescribed technical channel to the bank or financial institution, followed by service; transactions intended to defeat the measure are invalid under the article. Partnership-interest seizure is communicated to company management and the trade registry, with later service. Rights and receivables are communicated to the relevant natural or legal person. Seized property must be protected by measures needed to preserve its value and prevent damage.

Return is also regulated. When seized property is no longer needed and will not be confiscated, the prosecutor, judge or court must decide on return ex officio or on request, with refusal open to objection. Property belonging to the victim under Article 128 must be returned when it is no longer needed as evidence. That return rule does not allow a private party to bypass a genuine ownership dispute. The authority must identify the owner and the continuing evidentiary need.

A criminal complaint should therefore present facts and authentic supporting records, not demand a predetermined seizure or outcome. The prosecutor and judge determine investigative measures. A complainant may explain urgency and identified transaction paths, but cannot convert suspicion into a private entitlement over another person’s property.

7. Digital evidence, victim participation and the limits of a complaint

Criminal Procedure Code Article 134 permits a judge, or an urgent prosecutor subject to prompt judicial review, to order search, copying and transcription of a suspect’s computer data where concrete evidence creates strong suspicion and the evidence cannot be obtained otherwise. Devices may be seized when passwords, hidden data or the time needed for access prevents immediate copying, but they must be returned without delay after resolution and copying. A failed approval requires the statutory destruction consequence. The Constitutional Court has declared Article 134 invalid with effect from 25 February 2027; it remains in force at the research cut-off, so the event date and publication-day law must be checked.

A victim, person harmed by the offence, legally liable person or qualifying entity may declare a complaint and intervene in the public prosecution before judgment during first-instance proceedings. Intervention gives a procedural role; it does not transfer control of the prosecution or prove the civil debt. Counsel should keep a separate record of criminal submissions, civil pleadings, evidence disclosed under applicable rules and any restriction on use in another proceeding.

The complaint should distinguish known fact, document-supported inference and open question. A payment record may show a transfer to a named account. It may not reveal who controlled later transfers or whether a recipient had a lawful explanation. A social profile may help identify a spelling or possible connection, but it cannot establish that the person owns a photographed asset or participated in an offence. Public accusations can harm the investigation and third-party rights. Evidence should be delivered through a lawful, secure channel.

8. Fraud, confiscation and civil restitution are separate outcomes

The Criminal Code defines basic fraud through deceptive conduct that causes loss to another and benefit to the actor or another person. Article 158 applies the aggravated regime when one of its listed modalities is satisfied. These definitions guide criminal analysis; they do not permit a private publication or civil pleading to declare guilt. The exact representation, knowledge, causation, loss and benefit must be investigated, and the presumption of innocence continues to apply.

Object confiscation under Article 54 concerns instrumentalities, allocated property, crime-derived property and certain dangerous prepared property connected with an intentional offence. The provision protects good-faith third-party ownership and specified limited real rights. Gain confiscation under Article 55 concerns material benefits obtained from, forming the subject of or provided for crime, together with their economic gains, when they cannot be returned to the victim. If the benefit is unavailable, equivalent value may be addressed under the article.

Seizure is provisional; confiscation is a criminal judgment consequence. A seized account is not automatically confiscated, and confiscation does not automatically answer every private damages question. The statutory preference for return to the victim in the gain-confiscation rule makes ownership and traceability important, but it does not create a universal administrative payout. Competing victims, mixed funds, third-party rights and inability to identify the asset can complicate the result.

Voluntary full or partial restitution or compensation can affect sentencing for listed completed property offences under Article 168 at the stages and rates stated there. Partial restitution additionally requires victim consent. This sentencing mechanism is not a civil settlement mandate and does not assure actual payment. Any proposal should be assessed with the criminal file, civil claims, release language, authority and source of funds.

9. MASAK powers do not create a private freezing service

MASAK’s statutory functions form part of Türkiye’s anti-money-laundering public-law framework. An obliged entity must report an attempted or completed transaction when information, suspicion or reasonable grounds indicate an illegal origin or illegal use of assets. It must not disclose the suspicious-transaction report except to authorised persons. A public body, person or organisation requested by the Presidency or inspection officers must provide the requested information, documents and records, subject to the statute’s defence-related exception rather than ordinary secrecy objections.

The regime also interfaces with seizure. Where strong suspicion concerns laundering or terrorist-financing offences, the authority competent under Criminal Procedure Code Article 128, or the prosecutor in an urgent case subject to judicial approval, may use the Article 128 procedure under Law No. 5549. The report, approval and lapse requirements remain material. A separate transaction-suspension mechanism allows the Minister, or a deputy minister exercising delegated authority, to suspend a transaction or withhold permission for the statutory period when the domestic or qualifying foreign-request conditions are met.

These powers do not provide a complainant with a private right to direct MASAK, demand a report, command a bank freeze or collect the funds. There is no private right to direct MASAK. A report from an obliged entity is confidential, and its existence should not be assumed from account behaviour. A lawyer can organise lawful evidence for the appropriate authority and explain an identified urgency, while the competent public authority decides whether its threshold and powers are engaged.

The distinction also prevents false expectations. A bank’s internal compliance hold, a MASAK-related public-law suspension, a criminal seizure order, a civil injunction and a provisional attachment may all restrict a transaction in practice, but their sources, duration, review and beneficiaries differ. One should never be described as proof that another has been granted. Public-law preservation does not guarantee private recovery.

10. Cross-border procedure and a practical first review

Turkish courts’ international jurisdiction is generally identified through the domestic territorial-jurisdiction rules under Private International and Procedural Law Article 40. That general rule does not answer every contract, tort, exclusive-jurisdiction, arbitration or consumer issue. Governing law is a separate question. Foreign proceedings, awards and judgments may require recognition or enforcement before they can support Turkish execution, while an urgent Turkish measure may raise its own jurisdictional analysis.

A foreign person litigating, intervening or initiating enforcement in Türkiye generally provides security for costs and opposing-party loss unless the court grants the reciprocity-based exemption. Nationality, incorporation, treaties and reciprocal practice must be checked before an amount or exemption is stated.

Cross-border evidence also needs a country-specific route. Corporate extracts, powers of attorney, bank records and witness material may require apostille or consular legalisation, certified translation or a formal evidence request. Service abroad depends on the destination, address, treaty and document. Informal email delivery should not be used to invent a procedural trigger. Limitation and forfeiture analysis must use the underlying claim, governing law, event, knowledge, service, interruption and transition facts. This article calculates no personal date.

An initial review can nevertheless be concrete. Prepare a chronology, preserve native communications and bank records, list assets with lawful source and verification status, identify existing proceedings and state the objective of each proposed step. Record what is missing. Avoid contacting custodians in a way that risks dissipation or prejudices an investigation.

The first legal memorandum should then compare the available tracks. For each, it should name the applicant, decision maker, statutory threshold, evidence, security, forum, execution mechanism, objections, follow-on duties and realistic limits. Civil evidence, injunction, provisional attachment, avoidance and enforcement are different legal tracks from criminal preservation, seizure and confiscation. MASAK mechanisms remain a third public-law category. That structure allows urgent work without converting uncertainty into accusation or a promise.

Frequently asked questions

Official sources and source-cut-off warning

The principal official texts used are the Code of Civil Procedure No. 6100, Enforcement and Bankruptcy Law No. 2004, Criminal Procedure Code No. 5271, Criminal Code No. 5237, Law No. 5549 on Prevention of Laundering Proceeds of Crime, Code of Obligations No. 6098 and Private International and Procedural Law No. 5718. The seven official consolidated texts were rechecked on 4 October 2026 and matched the archived official files byte for byte. The future effect of the Constitutional Court decision concerning Criminal Procedure Code Article 134 remains date-sensitive, and current official law must be checked again on any later filing date. No high-court holding is attributed because the research package did not retrieve a stable, exact, current official decision corpus.

This article gives general legal information. A case review should identify the transaction, current procedural stage, available original evidence, verified Turkish connection and immediate preservation concern. That review can compare lawful routes and required evidence; it cannot promise that an asset will be found, frozen, confiscated or recovered.
