Anti-Money Laundering (AML) and Financial Crime Law in Turkey: MASAK Compliance, Asset Freezes, and Defense Guide

Quick Summary: Anti-Money Laundering and Combating the Financing of Terrorism in Türkiye are strictly governed by Law No. 5549 on the Prevention of Laundering Proceeds of Crime, Law No. 6415, and Article 282 of the Turkish Penal Code No. 5237. Enforced by the Financial Crimes Investigation Board (MASAK), Turkish AML regulations require banks, fintechs, crypto asset service providers, real estate agencies, and jewelers to conduct strict Know Your Customer (KYC) checks and report suspicious transactions. Whether you are a company seeking AML compliance programs or an individual/business facing a MASAK account freeze or money laundering investigation, prompt legal representation is critical to lifting asset blocks and protecting your freedom and reputation.

As Türkiye aligns its financial regulatory framework with international Financial Action Task Force (FATF) standards, enforcement against money laundering, wire fraud, illegal betting proceeds, and crypto-asset financial crimes has intensified dramatically. Both Turkish companies and foreign investors frequently encounter strict banking scrutiny, sudden transaction suspensions, or criminal investigations triggered by complex cross-border transfers or third-party payment disputes.

At Cosmos Legal Law Firm, we advise domestic and international businesses on designing statutory AML compliance frameworks, represent clients in challenging MASAK transaction suspensions and criminal asset seizures, and provide white-collar criminal defense in financial crime investigations across Türkiye.

1. Core Legal Framework Governing AML and Financial Crimes in Türkiye

Türkiye’s anti-money laundering and financial crime enforcement rests on three primary statutes:

• Laundering Proceeds of Crime (Article 282 of Turkish Penal Code No. 5237): Under Article 282 of the Turkish Penal Code No. 5237, transferring abroad, converting, disguising the illicit source of, or knowingly acquiring/possessing assets derived from a predicate offense carrying a minimum prison sentence of 6 months or more constitutes the crime of Money Laundering, punishable by 3 to 7 years of imprisonment and heavy judicial fines.
• Law No. 5549 on Prevention of Laundering Proceeds of Crime: Establishes preventive compliance duties for obliged institutions, customer identification rules, beneficial ownership verification, and the regulatory powers of MASAK (Financial Crimes Investigation Board).
• Law No. 6415 & Law No. 7262: Govern the prevention of terrorism financing and the proliferation of weapons of mass destruction, authorizing rapid administrative asset freezes and international sanctions enforcement.

2. Obliged Entities and Mandatory AML Compliance Duties

Under Law No. 5549 and secondary regulations enforced by the Ministry of Treasury and Finance, a wide range of institutions—known as Obliged Entities—must implement strict preventive controls:

• Who Is Subject to AML Obligations? Banks, payment and electronic money institutions, crypto asset service providers, capital market brokerage firms, insurance companies, real estate agencies and developers, precious metals/jewelry dealers, independent accountants, and notaries.
• Customer Due Diligence (CDD) & Ultimate Beneficial Owner (UBO) Identification: Obliged entities must verify client identity, confirm the Ultimate Beneficial Owner holding more than 25% of corporate shares, and apply Enhanced Due Diligence (EDD) to Politically Exposed Persons (PEPs) and high-risk jurisdictions.
• Suspicious Transaction Reporting (STR) & Tipping-Off Prohibition: When an obliged entity detects an unusual transaction inconsistent with a client’s financial profile, it must file a confidential Suspicious Transaction Report with MASAK. By law, institutions are strictly prohibited from disclosing to the customer that a report has been filed.
• 8-Year Record Retention Rule: All identification records, transaction receipts, and compliance files must be preserved for 8 years from the transaction date or account closure.

3. MASAK Transaction Suspensions and Criminal Asset Freezes

One of the most disruptive consequences of AML enforcement is the sudden freezing of personal or corporate bank accounts and crypto exchange wallets:

1. 7-Business-Day MASAK Suspension (Article 19/A of Law No. 5549): Upon detecting serious suspicion of money laundering or terrorism financing, MASAK has the statutory authority to suspend outgoing transactions on a bank or crypto account for 7 business days while evaluating the financial intelligence file.
2. Criminal Seizure and Account Freeze (Article 128 of Code of Criminal Procedure No. 5271): Before the 7-business-day MASAK hold expires, the Chief Public Prosecutor may apply to a Criminal Judgeship of Peace for a formal criminal seizure/freeze order under Article 128 of the Code of Criminal Procedure No. 5271, blocking bank accounts, real estate, vehicles, and company shares throughout the criminal investigation.
3. Administrative Asset Freezing Decisions: Under Law No. 6415, assets of individuals or entities linked to international sanctions lists or terrorism financing investigations may be frozen via Official Gazette decisions.

4. White-Collar Defense and Legal Remedies to Lift Account Freezes

When an innocent business or individual is caught in a financial crime investigation—such as unknowingly receiving fraudulent funds from a commercial buyer, engaging in peer-to-peer (P2P) crypto trades, or experiencing cross-border wire compliance flags—immediate legal action is essential:

• Submitting a Source-of-Funds Compliance Dossier: Legal counsel prepares a comprehensive evidentiary file containing underlying commercial contracts, tax invoices, customs declarations, bank statements, and corporate ownership records proving that the disputed funds originate from legitimate economic activity.
• Filing Objections Before Criminal Judgeships of Peace: Under the Code of Criminal Procedure, defense counsel can file a formal objection petition challenging unlawful or disproportionate asset freezes, demonstrating the absence of criminal intent or predicate offense connection.
• Corporate AML Risk Audits: For fintech companies, crypto platforms, real estate firms, and international trading companies operating in Türkiye, implementing a tailored AML Compliance Program and appointing a certified Compliance Officer shields company directors from heavy MASAK administrative fines and criminal liability.

5. Immigration Consequences for Foreign Nationals in Financial Crime Cases

For foreign investors, expats, and international businesspeople in Türkiye, involvement in an AML or financial crime investigation carries severe secondary immigration risks:

• Immigration Restriction Codes & Deportation: Under Article 54 of the Law on Foreigners and International Protection No. 6458, foreign nationals investigated for financial crimes, fraud, or money laundering may be issued security restriction codes (such as G-87 or V-87) by the Presidency of Migration Management, leading to residence permit cancellations or deportation proceedings even prior to a court conviction.
• Dual-Track Legal Defense: Protecting a foreign national requires simultaneous white-collar criminal defense to secure acquittal or non-prosecution, alongside administrative litigation to challenge deportation orders and lift entry bans.

Frequently Asked Questions (FAQ)

• My company bank account was frozen after receiving payment from a foreign client whose funds were later flagged. Can we unfreeze our account?
  Yes. Under Turkish criminal law, a good-faith merchant who received payment for genuine goods or services without knowledge of any illicit origin is not guilty of money laundering. Submitting verified commercial contracts, export/import invoices, and shipping documents to the Prosecutor and Criminal Judgeship of Peace provides strong grounds to lift the freeze.
• What happens if a crypto exchange or real estate company in Türkiye fails to perform KYC checks?
  Under Law No. 5549, MASAK imposes severe administrative fines per violation on obliged entities that fail to verify customer identity, report suspicious transactions, or establish internal compliance programs—and may revoke operating licenses in cases of repeated non-compliance.
• Can a foreign national challenge a MASAK freeze or criminal investigation in Türkiye from abroad?
  Yes. By issuing an apostilled Power of Attorney to a Turkish criminal defense lawyer, foreign individuals and corporate directors can access investigation files, submit source-of-funds evidence, file objections against asset freezes, and defend their legal rights without traveling to Türkiye.
