Money Laundering Investigation in Turkey

Money laundering is different from the predicate offence, tax non-compliance, unexplained wealth, a bank's suspicious-transaction report and civil ownership. A MASAK report is evidence and analysis, not a conviction. Private blocking, Law 5549 transaction postponement and CMK seizure are provisional measures reviewed under separate rules; neither the existence nor release of a freeze determines the TCK Article 282 elements addressed here.

The investigation may close, the court may acquit, or the court may convict under the specifically proved Article 282 alternative. A complete transaction map can separate legitimate capital, loans, inheritance, sale proceeds and business turnover from alleged criminal proceeds and test individualized knowledge and purpose. The outcome here is a merits decision on criminal liability, not an order lifting, narrowing or returning restrained property.

Control point	Legal test	Evidence source
Predicate offence	Identify the alleged offence, actor, jurisdiction, time and six-month statutory-minimum threshold.	Indictment, foreign judgment/request and underlying transaction evidence
Knowledge	Role, access, warnings, due diligence and communication determine whether the defendant knew the criminal source.	KYC files, board records, messages, professional advice and account permissions
Purpose	Complexity or foreign routing alone does not prove concealment or lawful-appearance purpose.	Commercial rationale, invoices, tax, logistics, pricing and counterparties
Charged alternative and attribution	The indictment must distinguish concealment or lawful-appearance conduct from knowing purchase, acceptance, possession or use, and attribute that alternative to the individual defendant.	Indictment, role matrix, account permissions, communications and transaction chronology
Substantive scope gate	This profile tests Article 282 guilt; the legal basis, duration, proportionality and release of a freeze or seizure must be checked in the separate CMK asset-restraint profile.	Merits indictment and evidence index kept separate from restraint orders, bank notices and return applications

Legal basis and governing rules

Legal basis — Qualifying predicate

TCK Article 282 applies to assets derived from an offence carrying a statutory minimum imprisonment of six months or more. Official source: 5237 Turkish Criminal Code (TCK).

The prosecution must identify the predicate conduct and show why it meets the threshold rather than relying on unexplained wealth alone.

Legal basis — Concealment or lawful appearance

The principal Article 282 form requires foreign transfer or transactions performed to conceal the unlawful source or create an appearance of lawful acquisition. Official source: 5237 Turkish Criminal Code (TCK).

Legal basis — Knowing receipt or use

Article 282 separately criminalizes knowingly purchasing, accepting, possessing or using assets derived from the qualifying predicate offence. Official source: 5237 Turkish Criminal Code (TCK).

Access to an account or company title is not a substitute for proof of knowledge.

Legal basis — Financial intelligence is not guilt

Law 5549 establishes preventive obligations, suspicious-transaction reporting and MASAK's financial-intelligence framework, while criminal liability remains governed by the elements of TCK Article 282. Official source: 5549 Law on Prevention of Laundering Proceeds of Crime.
