Unblocking Frozen Bank Accounts, MASAK Compliance and CMK 128 Seizure Objections in Istanbul

Foreign investors, international traders, exporters, and cryptocurrency users holding personal or corporate accounts at Turkish banks in Istanbul increasingly encounter sudden bank account freezes (Banka Hesap Blokesi) where online banking is locked and incoming/outgoing SWIFT or FAST transfers are suspended without prior warning. In Istanbul, a bank account freeze typically originates from one of four distinct legal mechanisms: a prosecutorial or judicial seizure order under Article 128 of the Criminal Procedure Code (CMK No. 5271), an urgent 7-day transaction suspension under Article 19/A of the Prevention of Laundering Proceeds of Crime Law No. 5549 (MASAK), an internal bank compliance review triggered by peer-to-peer (P2P) crypto/USDT transfers, or a civil/tax attachment (E-Haciz). Kalem Law Office, led by Attorney Enes Nergiz (Antalya Bar Association Reg. No: 6281), represents foreign account holders before the Istanbul Chief Public Prosecutor’s Offices, Peace Criminal Judgeships (Sulh Ceza Hakimliği), MASAK, and bank legal compliance directorates to identify the exact legal basis of the freeze and restore access to funds.

1. Prosecutorial & Judicial Account Freezes Under CMK Article 128 & Law No. 5549 Art. 19/A

When a third party who transferred Turkish Lira to your account (for example, during an OTC/P2P cryptocurrency exchange on Binance/Garanti/Ziraat/Kuveyt Türk, a real estate deposit, or a commercial goods sale) is later linked to an online fraud (TCK Art. 158) or unauthorized betting investigation (Law No. 7258), the investigating prosecutor in Istanbul often freezes the entire chain of recipient accounts:

• Urgent 7-Day Suspension Under MASAK Law No. 5549 Art. 19/A & New CMK Art. 128A Mechanisms: Financial institutions or the prosecutor may temporarily suspend a suspicious transaction or account balance while MASAK or the cybercrime bureau traces the funds.
• Formal Seizure Under CMK Article 128 (El Koyma Kararı): For a long-term freeze of bank accounts, real estate, or crypto-exchange wallets, the prosecutor must obtain a formal decision from the Istanbul Peace Criminal Judgeship (Sulh Ceza Hakimliği) supported by a technical financial report (from MASAK, BDDK, or SPK).
• 7-Day Objection & Source-of-Funds Defense (Kaynağın İspatı): Our criminal defense attorneys immediately inspect the prosecutor’s investigation file in Çağlayan, Kartal, or Bakırköy (or via UYAP if issued by another province), submit documented proof of the underlying lawful transaction (such as verified P2P crypto trade order logs, commercial customs declarations, or notarized sale agreements), and request that the freeze be lifted altogether or strictly limited to the disputed incoming amount rather than the client’s entire life savings or corporate working capital.

2. Internal Bank KYC/AML Compliance Closures vs. Tax & Civil Execution Freezes (E-Haciz)

Not every bank block in Istanbul is criminal. Before filing a petition, counsel must distinguish between the four types of Turkish account blocks:

Frequently Asked Questions (FAQ)

Why was my entire Turkish bank account frozen over a single P2P crypto (USDT) transfer I received?

When a fraud victim transfers money from their bank account directly to your IBAN while a third-party scammer collects your USDT on a P2P platform ("triangulation fraud"), the victim reports your IBAN to the prosecutor. The Peace Criminal Judgeship then places a CMK Art. 128 block on your account. By presenting the timestamped P2P trade history, counterparty KYC data, and chat logs to the prosecutor through defense counsel, we demonstrate your good-faith third-party status and petition to lift the freeze.

Can a prosecutor freeze my entire account balance if the disputed transfer was only a small amount?

Under Article 128 of the CMK and established constitutional proportionality principles, seizure must be strictly limited to the alleged proceeds of the offense (Suçtan Elde Edilen Değer). When a bank mistakenly freezes the entire account rather than just the disputed amount, our attorneys file an immediate petition with the Prosecutor’s Office and Peace Criminal Judgeship to release the uncontested balance.

Can my frozen bank account in Istanbul be unblocked by Power of Attorney without my traveling to Turkey?

Yes. With an apostilled or Turkish Consulate Power of Attorney, our attorneys can inquire with the bank’s legal headquarters in Istanbul, inspect the criminal investigation file or enforcement docket, submit the financial evidence dossier, and file all judicial objections on your behalf.

What happens if a Turkish bank decides to close my account due to internal compliance rules?

While a commercial bank may terminate a banking relationship under its general service contract if there is no judicial seizure order in place, the bank has zero legal right to confiscate your funds: upon receiving formal legal notice, the bank must disburse or wire the remaining lawful balance to an account designated by you or your duly authorized attorney.
