Commercial Fraud, Asset Tracing & White-Collar Crime in Turkey

We represent multinational corporations, foreign investors, private equity funds, and international victims in investigating commercial fraud, seeking court asset freezes (criminal seizure under CMK 128, precautionary attachment under İİK 257), prosecuting white-collar offenses, and pursuing the recovery of siphoned corporate capital under Turkish law.

Av. Onur ÇalışıcıIstanbul Bar reg. no 83426

In brief

  1. Aggravated fraud under TCK Article 158/1-h (fraud by merchants, company managers or persons acting on behalf of a company in the course of their commercial activities) carries 3 to 10 years' imprisonment and a judicial fine of up to 5,000 days; the rule that the fine may not be less than twice the gain applies only to sub-paragraphs (e), (f), (j), (k) and (l), not to (h).
  2. Criminal seizure under CMK Art. 128 requires a judge's decision and a report on the value of the criminal proceeds from the BRSA, the Capital Markets Board, MASAK, the Treasury or the Public Oversight Authority, which is prepared within three months (extendable by two). The faster route is CMK Art. 128/A: for qualified fraud under TCK 158/1-f or (l) and certain other listed offences, the bank, payment service provider or crypto-asset service provider may suspend the account used in the offence for up to 48 hours, and seizure during that period does not require the report.
  3. Under Law No. 5549 Art. 19/A, the Minister (not MASAK) may suspend a transaction, or refuse to let it proceed, for seven business days where there is a suspicion that the assets are linked to money laundering or terrorist financing.
  4. Managing directors who siphon company capital or execute fraudulent affiliate transfers face personal civil liability under TCC Art. 553 (joint and several with other liable persons only to the extent the damage is attributable to each of them, TCC Art. 557) alongside criminal breach-of-trust charges under TCK Art. 155; the penalty is increased by one fold where the asset is a motor land, sea or air vehicle (TCK Art. 155/3, in force 25 December 2025).
  5. Our dual-track strategy combines criminal proceedings with civil precautionary attachment (İİK Art. 257) and the action for annulment of fraudulent transactions (İİK Arts. 277-284) to pursue asset recovery.

Sophisticated commercial fraud, corporate embezzlement, trade finance scams, and premeditated fraudulent bankruptcies represent serious risks for international companies investing in or trading with Turkey. When corporate capital is siphoned through shell entities, forged documents, or corrupt management, a demand letter or a slow civil lawsuit alone rarely keeps the assets within reach.

Lex Lata provides legal counsel for multinational enterprises, international trading houses, foreign shareholders, and private equity funds. We combine the coercive tools of Turkish Criminal Procedure (CMK No. 5271) with the asset-seizure remedies of Enforcement & Bankruptcy Law (İİK No. 2004) and Corporate Law (TCC No. 6102) to trace, freeze, and recover stolen assets.


1. Aggravated Commercial Fraud Prosecution (TCK Art. 158)

Under the Turkish Penal Code (Law No. 5237), fraud in the commercial sphere is often prosecuted as Aggravated Fraud (Nitelikli Dolandırıcılık):

Show the 3 points
  • Fraud in the Course of Commercial Activity (TCK Art. 158/1-h): Fraud committed by merchants, company managers or persons acting on behalf of a company in the course of their commercial activities, or by cooperative managers within the cooperative’s activities.
  • Fraud Using Information Systems, Banks or Credit Institutions (TCK Art. 158/1-f): Fraud in which information systems, banks or credit institutions are used as an instrument, for example through electronic banking or digital payment channels.
  • Fraud Using Public Bodies or Legal Entities (TCK Art. 158/1-d): Fraud in which public institutions, public professional bodies, political parties, foundations or associations are used as an instrument. Forging an official document is a separate offence (TCK Art. 204).

Aggravated fraud carries 3 to 10 years of imprisonment and a judicial fine of up to 5,000 days. For sub-paragraphs (e), (f), (j), (k) and (l), the minimum prison term is four years and the fine may not be less than twice the gain obtained. The penalty is increased by half where the offence is committed jointly by three or more persons, and by one fold where it is committed within the activity of a criminal organisation (TCK Art. 158/3).


2. Criminal Asset Freezing & Seizure (CMK Art. 128)

The cornerstone of white-collar asset recovery is ensuring that assets do not vanish during the investigation. Under Article 128 of the Criminal Procedure Code, only a judge may order seizure (CMK 128/9); during the investigation this is the Criminal Judgeship of Peace (Sulh Ceza Hakimliği) acting on the prosecutor’s request. Strong suspicion, based on concrete evidence, that the offence was committed and that the assets derive from it is required, together with a report on the value of the proceeds (CMK 128/1). Theft, breach of trust (TCK 155), fraud (TCK 157, 158) and fraudulent bankruptcy (TCK 161) are among the offences listed in CMK 128/2.

Read the full section

Assets That May Be Seized (CMK Art. 128/1):

  1. Bank Accounts & Deposits: Accounts of every kind at banks and other financial institutions; the order is notified to the bank immediately by technical means.
  2. Real Estate Holdings: Seizure annotations (el koyma şerhi) on Land Registry (TKGM) records.
  3. Corporate Shares & Equity: Partnership shares in Turkish Joint Stock (A.Ş.) and Limited Liability (Ltd. Şti.) companies, notified to the company and the trade registry.
  4. Vehicles & Vessels: Land, sea and air vehicles, by annotation in the register where they are recorded.
  5. Other Assets: Rights and receivables, negotiable instruments, safe-deposit box contents and “other assets” (CMK 128/1-h); crypto assets held with crypto-asset service providers are not named in the article but can be assessed under this heading.

Separately, CMK Art. 128/A (added in December 2025) allows the bank, payment service provider or crypto-asset service provider to suspend an account used in qualified fraud under TCK 158/1-f or (l), qualified theft under TCK 142/2-e or misuse of bank or credit cards (TCK 245) for up to 48 hours; seizure within that period can be ordered by a judge, or in urgent cases by the prosecutor’s written order subject to a judge’s approval, without the valuation report.


3. Financial Crimes Investigation Board (MASAK)

Under Law No. 5549, the Financial Crimes Investigation Board (MASAK) functions as Turkey’s financial intelligence unit.

Read the full section

Under Article 19/A of Law No. 5549, where there is a suspicion that the assets in a transaction are linked to money laundering or terrorist financing:

  • The Minister May Suspend the Transaction for 7 Business Days: The Minister (who may delegate this to a deputy minister) may suspend the transaction or refuse to let it proceed for that period.
  • MASAK Confirms and Analyses: The suspension serves to let MASAK confirm the suspicion, analyse the transaction and, where needed, refer the results to the competent authorities.

4. Director Embezzlement & Piercing the Corporate Veil (TCC Art. 553)

Foreign investors in Turkish joint ventures frequently encounter local managing directors who divert company revenue into private accounts or affiliate companies.

5. Dual-Track Litigation Strategy: Simultaneous Criminal & Civil Action

Relying solely on civil litigation allows fraudsters time to dissipate capital, while criminal cases alone do not automatically enforce monetary restitution. Lex Lata runs both tracks together:

Show the 4 points
  1. Freezing: We file a criminal complaint requesting a CMK 128 seizure while applying to the competent court for a civil Precautionary Attachment (İİK 257).
  2. Evidence: Where evidence risks being lost, the court may be asked to order an expert examination as preservation of evidence (HMK 400 Delil Tespiti); bank records are obtained through the prosecutor or the court.
  3. Proceedings: We pursue the criminal case, as a rule before the Criminal Court of First Instance (asliye ceza mahkemesi), or before the High Criminal Court where TCK 158/3 raises the maximum above ten years, while pursuing civil liability under TCC Art. 553 and TCO Art. 49 and the annulment action under İİK Art. 277 et seq. Where the file also carries fraudulent bankruptcy (TCK Art. 161), that charge is tried before the High Criminal Court.
  4. Enforcement: Where proceeds were seized under CMK 128/A (only for TCK 142/2-e, 158/1-f and (l), and 245; not for fraud under 158/1-h), the proceeds found to belong to the victim are returned to their owner during the investigation or prosecution (CMK 128/A/5). Confiscation under TCK 55 applies only where proceeds cannot be returned to the victim; attached assets are collected through the enforcement office and remitted to the client’s account.

Strategic 5-Step Asset Recovery & Corporate Investigation Process

  1. 1. Asset and Record Review

    Company ERP records, bank transactions, MERSİS corporate registries, and Land Registry (TKGM) holdings are reviewed, with independent forensic accountants where the case needs them, to identify assets.

  2. 2. Parallel Freezing Applications

    A criminal complaint asks the prosecutor to seek a CMK 128 seizure from the criminal judgeship of peace, while a precautionary attachment (İİK 257) is sought from the competent court over the identified assets.

  3. 3. MASAK and Money-Laundering Concerns

    Where the funds may be laundered, the information is put before the prosecutor and MASAK; a transaction suspension under Law 5549 Art. 19/A is a decision of the Minister, not of MASAK or the victim.

  4. 4. Criminal Prosecution & Veil-Piercing

    We pursue criminal proceedings for aggravated fraud, as a rule before the Criminal Court of First Instance (asliye ceza mahkemesi); where TCK 158/3 applies (three or more persons: up to 15 years; criminal organisation: up to 20 years) the High Criminal Court has jurisdiction because the maximum exceeds ten years (Law 5235 Art. 12). At the same time we file civil director liability lawsuits under TCC Art. 553 against managing fiduciaries. A fraudulent bankruptcy charge under TCK Art. 161 is also tried before the High Criminal Court.

  5. 5. Collection & Cross-Border Remittance

    Once the claim is established and the precautionary attachment becomes an executory attachment (İİK 264), attached funds are collected and real estate or shares are sold through the enforcement office's electronic auction, with proceeds transferred to the client.

Frequently asked questions

What constitutes criminal commercial fraud under Turkish law?

Under Turkish Penal Code (TCK) Article 158, commercial fraud requires proof of pre-existing fraudulent intent (dolus directus) and sophisticated deceptive machinations (hileli desise) that induced the victim into transferring assets, rather than simple subsequent contractual non-performance.

How quickly can we freeze a fraudster's bank accounts and assets in Turkey?

Two routes, and they move at different speeds. A civil application for Precautionary Attachment (İhtiyati Haciz, İİK Art. 257) is decided by the court competent under İİK Art. 50, which is free to hear or not to hear the parties (Art. 258), so the order can be made without hearing the debtor and can reach bank accounts, real estate and company shares. On the criminal side, seizure under CMK Art. 128 requires a judge's decision and a report from the BRSA, the Capital Markets Board, MASAK, the Treasury or the Public Oversight Authority on the value of the criminal proceeds; the report is prepared within three months, extendable by two. The faster criminal route is CMK Art. 128/A, added in December 2025: on reasonable suspicion of qualified fraud under TCK 158/1-f (using information systems, banks or credit institutions) or (l), among other listed offences, the bank, payment service provider or crypto-asset service provider itself may suspend the account for up to 48 hours, and a seizure made within that period does not require the valuation report.

How does MASAK assist in cross-border fraud investigations?

Under Law No. 5549 Art. 19/A the Minister, not MASAK, may suspend a transaction for seven business days where there is a suspicion that the assets are linked to money laundering or terrorist financing. The purpose is to let MASAK confirm the suspicion, analyse the transaction and, where needed, refer the results to the competent authorities.

Can we pursue the personal assets of company directors who hid behind a Turkish Ltd. or A.Ş.?

Yes. Under Turkish Commercial Code (TCC) Article 553, founders, board members, managers and liquidators who culpably breach their duties under the law and the articles of association are liable to the company, the shareholders and the company's creditors for the damage they cause, and their personal assets can be pursued. Separately, the doctrine of Piercing the Corporate Veil (Tüzel Kişilik Perdesinin Aralanması), which rests on Civil Code (TMK) Art. 2, allows the corporate form to be disregarded where it is abused. Where several persons are liable for the same damage, each is jointly and severally liable to the extent the damage is personally attributable to them by reason of their fault and the circumstances (TCC Art. 557).

What happens if the fraudster transferred assets to family members or shell companies?

Under Enforcement & Bankruptcy Law (İİK) Articles 277 to 284, a creditor holding a certificate of insufficiency (aciz belgesi), or the bankruptcy administration, can file an Action for Annulment (Tasarrufun İptali Davası). Gifts and gratuitous dispositions made within one year before the certificate or the bankruptcy are open to annulment, and transfers to close relatives are treated as gifts unless shown to be for fair value (Art. 278). Transactions made by a debtor whose assets do not cover its debts, with intent to harm creditors, can be annulled where the other party knew of the debtor's financial position and intent or there were clear signs that should have made it known, provided enforcement or bankruptcy proceedings began within five years of the transaction; the other party is presumed to know if it is the debtor's spouse, a direct ascendant or descendant, a blood or in-law relative up to the third degree, or an adoptive parent or adopted child (Art. 280). The right of action lapses five years after the transaction (Art. 284); a successful claimant may enforce directly against the transferred asset (Art. 283).

Can a red notice be sought through INTERPOL for fraudsters who have fled Turkey?

A red notice request first requires an arrest warrant: during the investigation it is issued by the criminal judgeship of peace on the prosecutor's request, and during the prosecution by the judge or the court (CMK Art. 98). Whether the notice is published is a matter for INTERPOL, and whether the person is surrendered is a decision of the state where they are found.

Can foreign victims manage the entire investigation and litigation remotely?

In most matters, yes. With a notarized and Apostilled or consular-certified Power of Attorney, complaints, applications and court filings are made and followed through the UYAP national judicial network, and counsel attends hearings on the client's behalf.
