Foreign investor facing fraud, money laundering, suspicious bank transfers or asset seizure in Turkey? Learn about criminal investigations, MASAK scrutiny, frozen accounts, company liability, crypto assets and defense strategies in 2026.

A foreign investor accused of financial crime in Turkey can face several legal and commercial risks at the same time. A prosecutor investigation may concern suspicious bank transfers, alleged fraud, money laundering, cryptocurrency transactions, misuse of company accounts, unexplained international payments or funds allegedly connected with another suspect. At the same time, bank accounts or other assets may become restricted, company operations may be disrupted and the foreign investor may become concerned about detention, a judicial travel ban, residence status or deportation. The existence of suspicious financial activity does not itself establish criminal responsibility. Turkish criminal liability must be assessed according to the specific offense and the individual investor’s conduct, knowledge, intent and participation. This distinction is particularly important where the foreign investor is merely a shareholder while Turkish directors, employees, accountants or business partners actually control daily transactions. Turkey’s financial-crime framework also allows significant investigative measures. Under Law No. 5549, where there is strong suspicion of money laundering or terrorism financing, asset values may be seized through the procedure connected with Article 128 of the Criminal Procedure Code; in urgent cases, a prosecutor may also order seizure subject to statutory judicial-approval requirements. (Masak)

Why Can a Foreign Investor Become Involved in a Financial Crime Investigation?

Foreign investment frequently involves large international transfers, shareholder loans, capital contributions, acquisition payments, intercompany transactions, management fees, royalties, dividends and payments connected with imports or exports. None of these transactions is inherently criminal. Problems arise when prosecutors or financial institutions question the economic purpose or origin of the funds, when a counterparty becomes the subject of a fraud investigation or when money entering the investor’s company account is alleged to represent criminal proceeds.

A Suspicious Transaction Is Not the Same as a Crime

Banks and other obliged institutions have suspicious transaction reporting obligations under Turkey’s anti-money-laundering framework. MASAK’s updated reporting guidance reflects sector-specific risks and the updated National Risk Assessment. (Masak) A suspicious transaction report is therefore part of a preventive financial-intelligence system; it should not be confused with proof that the investor committed money laundering, fraud or another offense.

The First Question: What Exactly Are You Accused Of?

“Financial crime” can describe very different allegations. A foreign investor may be investigated for fraud, qualified fraud, money laundering, misuse of banking accounts, alleged participation in fraudulent transactions, cryptocurrency-related activity or another offense connected with company finances. The defense strategy cannot be prepared properly until the exact allegation and disputed transactions are identified.

Determine Your Procedural Status Immediately

A person may appear in a criminal investigation as a suspect, witness, complainant or another relevant party. Do not assume your status merely because the police, bank or business partner contacted you.

Identify the Investigation File

Where legally accessible, determine which prosecutor’s office is conducting the investigation, the investigation number and the suspected offense.

Identify the Transactions Under Investigation

Financial investigations can involve thousands of pages of bank records. The defense should isolate the transactions that actually triggered suspicion.

Prepare a Transaction Matrix

For every disputed payment establish Date → Sender → Recipient → Amount → Currency → Commercial Purpose → Contract/Invoice → Person Who Authorized Payment → Subsequent Destination → Supporting Evidence.

Foreign Shareholder Does Not Automatically Mean Criminally Responsible Director

One of the most important distinctions in foreign-investment cases concerns ownership and management.

Share Ownership Is Not Proof of Personal Participation

A person may own 80% or 100% of a Turkish company while having little involvement in its daily banking operations.

Identify Who Actually Managed the Company

Was daily management performed by a Turkish director, general manager, finance director, accountant or local business partner?

Identify Who Controlled Internet Banking

Banking authority can become critical evidence.

Who Had the Passwords and Authentication Devices?

Determine which individuals could actually initiate transactions.

Who Approved Payments?

Internal authorization records can establish whether the foreign investor had any involvement.

Who Communicated With Customers?

Where fraud is alleged, identify the person who made the alleged false representations.

Who Received the Financial Benefit?

Following the money beyond the investor or company account can materially change the case.

Example: Foreign Investor and Local Business Partner

A foreign investor owns 70% of a Turkish company but lives abroad. A Turkish partner manages operations and has exclusive access to company internet banking. Several customers later allege that they were deceived and transferred money into the company account. The manager subsequently transfers the money to other accounts.

The fact that the foreign investor owns 70% of the company does not answer whether the investor knew about or participated in the alleged fraud.

Corporate Records Become Critical

Preserve shareholder agreements, articles of association, signature circulars, board resolutions, powers of attorney, employment agreements and banking authorization documents.

Do Not Change Corporate Records After the Investigation Begins

Backdated resolutions or retrospectively created documents can severely damage credibility.

Suspicious International Bank Transfers

International transfers often receive attention because investigators may need to establish the source, purpose and ultimate beneficiary of the funds.

A Large Transfer Is Not Automatically Money Laundering

A EUR 5 million transfer may simply represent acquisition financing, shareholder investment or payment for commercial goods.

The Transaction Must Be Explainable

The investor should be able to establish why the money moved and what economic activity supported it.

Source of Funds

Source-of-funds evidence establishes where the specific money involved in the transaction originated.

Example

Foreign Company Sale → EUR 8 Million Sale Proceeds → Investor’s Foreign Bank Account → EUR 3 Million Transfer → Turkish Investment Company.

The documentary chain may include the share sale agreement, foreign banking records, tax documents, Turkish bank transfer and corporate investment documents.

Source of Wealth

For substantial investments, it may also become necessary to explain how the investor accumulated their broader wealth.

Evidence Can Include

Business-sale proceeds, dividends, investment income, employment income, inheritance, real-estate transactions and historical financial records can be relevant depending on the circumstances.

Do Not Wait Until the Investigation Advances

Foreign banking records can take time to obtain. Historical documents should be secured as early as possible.

Shareholder Loans

Foreign investors frequently finance Turkish companies through shareholder loans.

Document the Loan Properly

The underlying agreement, corporate authorization, bank transfer and accounting treatment should correspond with one another.

Capital Contributions

Capital injections should be supported by the relevant corporate and banking documentation.

Intercompany Transfers

Payments between related companies may involve management services, cost sharing, intellectual-property licensing, financing or procurement.

Related-Party Status Does Not Make the Transaction Criminal

But the economic purpose should be demonstrable.

Fake Invoice Allegations

A prosecutor may question whether an invoice represents genuine goods or services or was created merely to provide a commercial appearance to a transfer.

An Invoice Alone May Not Be Enough

Preserve evidence of actual performance.

For Goods

Purchase orders, customs declarations, bills of lading, warehouse records, delivery documents and correspondence may be relevant.

For Services

Project files, reports, emails, deliverables, meeting records and other performance evidence can help demonstrate that the service genuinely existed.

Fraud Allegations Against Foreign Investors

Financial fraud investigations often begin with victim complaints concerning investment schemes, online transactions or company payments.

Determine Who Made the Alleged Misrepresentation

If the investor never communicated with the alleged victim, identify who did.

Determine Who Provided Payment Instructions

The person who instructed the victim to transfer money may be particularly important.

Determine Who Controlled the Receiving Account

A corporate account may be registered to the company while being operated by a particular employee or director.

Follow the Money After Receipt

If funds immediately left the company account, identify the recipient.

Example

Alleged Victim → Turkish Company → Supplier Company → Individual Director → Cryptocurrency Exchange.

This transaction chain may reveal roles that are not obvious merely from corporate ownership.

Internet Banking Fraud and Account Sharing

Financial-crime investigations increasingly focus on the use of bank and digital accounts by other persons. The Ministry of Justice has specifically warned that fraud networks recruit individuals to provide bank accounts, GSM lines and digital-account access. (Ankara Bati)

Important 2026 Amendment

Law No. 7589, published on 31 July 2026 as part of the 12th Judicial Package, amended the treatment of certain forms of participation in fraud. According to the Ministry of Justice, where participation in fraud or qualified fraud is limited to providing another person, for unlawful benefit, with information or means necessary to use a bank/payment instrument or an account at a bank, intermediary institution, payment service provider or crypto-asset service provider, the applicable sentence is reduced by half. (Türkiye Cumhuriyeti Adalet Bakanlığı)

This Does Not Legalize Account Sharing

The amendment does not mean that providing an account for fraudulent activity is lawful. Instead, it distinguishes a limited form of participation from broader involvement in the underlying fraud.

Foreign Investors Should Examine Who Used Corporate Accounts

Where a local manager or employee had access to company accounts, determine whether that access was authorized and what transactions were performed.

Money Laundering Allegations

Money-laundering investigations require particularly careful reconstruction of the origin and movement of assets.

Do Not Defend the Case Merely by Saying “The Money Was Legal”

Prove why it was legal.

Build the Financial Chain

Underlying Lawful Activity → Original Payment → Bank Account → International Transfer → Turkish Account → Investment/Commercial Transaction.

What If Criminal Money Entered the Investor’s Account Without Their Knowledge?

The investigation should determine why the payment was received, whether the investor knew the sender, what explanation was given and what happened to the funds afterward.

Do Not Move Questioned Funds After Learning of the Investigation

Transferring them abroad, converting them into cryptocurrency or withdrawing them in cash can create additional evidentiary issues.

Preserve the Existing Position

Where possible and legally appropriate, maintain complete records showing the status and movement of disputed funds.

MASAK Investigation

Foreign investors sometimes describe any banking restriction as a “MASAK investigation.” That description can be misleading.

Several Different Processes May Exist

A bank may conduct internal compliance checks, a transaction may become subject to an AML-related postponement mechanism, or a prosecutor or court may impose a criminal-procedure asset measure.

Transaction Postponement Is a Specific Mechanism

Turkey’s AML framework contains procedures allowing transactions involving assets suspected of connection with money laundering or terrorism financing to be suspended or prevented under specified conditions. (Masak)

Judicial Asset Seizure Is Different

Law No. 5549 Article 17 provides that where there is strong suspicion of money laundering or terrorism financing, assets may be seized through the procedure under Article 128 of the Criminal Procedure Code. (Masak)

Urgent Prosecutor Seizure

In urgent circumstances covered by Article 17, a prosecutor may issue a seizure decision. A seizure implemented without a judicial decision must be submitted to the competent judge within 24 hours, and the judge must decide on approval within another 24 hours. The provision also contains a subsequent three-month requirement concerning the Article 128 valuation report following judicial approval. (Masak)

A Frozen Bank Account Does Not Mean the Money Has Been Permanently Confiscated

A protective restriction imposed during an investigation should be distinguished from final confiscation.

Can a Foreign Investor Challenge an Asset Freeze?

Potentially. The appropriate remedy depends on the authority issuing the restriction, its legal basis and the procedural stage.

Obtain the Actual Decision

Do not prepare the defense solely from what the bank says by telephone.

Identify the Scope

Does the measure affect one account, all Turkish accounts, company accounts, shares, real estate or other assets?

Identify the Alleged Criminal Amount

Suppose the disputed transaction is TRY 2 million while the investor has TRY 30 million derived from documented legitimate investment activity. The relationship between the alleged criminal transaction and the broader restriction should be analyzed carefully.

Separate Legitimate Funds From Disputed Funds

Prepare:

Opening Balance → Legitimate Investment → Ordinary Business Revenue → Disputed Transaction → Subsequent Transfers → Current Balance.

Document Pre-Existing Assets

Assets acquired before the alleged offense may require separate consideration.

Real Estate

Preserve purchase agreements, bank transfers, title records and financing documents.

Company Shares

Preserve acquisition agreements and evidence showing how the purchase price was funded.

Vehicles and Other Investments

Establish purchase dates and lawful funding sources.

Cryptocurrency

Preserve exchange histories, wallet addresses and transaction hashes.

Crypto Assets in Financial Crime Investigations

Foreign investors increasingly hold Bitcoin, USDT, Ethereum or other digital assets. Crypto involvement does not itself establish money laundering.

Connect Fiat and Crypto Evidence

A useful chronology may show:

Foreign Investment Income → Bank Account → Crypto Platform → BTC Purchase → Personal Wallet.

Do Not Provide Only a Wallet Screenshot

A wallet balance does not establish the lawful origin of the assets.

Preserve Exchange KYC and Transaction Records

Historical account records can help connect real-world identity with blockchain transactions.

Follow the Crypto Trail

Where questioned money was converted into cryptocurrency, reconstruct:

Bank Transfer → Exchange → Cryptocurrency Purchase → Wallet → Subsequent Wallet → Final Known Destination.

Company Assets Versus Personal Assets

A major issue in investor investigations is distinguishing company property from shareholder property.

Do Not Treat the Company Account as the Investor’s Personal Wallet

Mixing personal and corporate funds can create substantial evidentiary and commercial problems.

If Mixing Already Occurred

Reconstruct each transfer and establish whether it was a shareholder loan, expense reimbursement, dividend, capital contribution or another transaction.

Foreign Investor Versus Company Criminal Exposure

The conduct attributed to natural persons should be analyzed separately from consequences potentially affecting a legal entity.

Do Not Allow Corporate Titles to Replace Evidence

“Shareholder,” “director” and “beneficial owner” describe legal relationships. They do not automatically establish who performed a particular criminal act.

Search and Seizure of Company Records

Financial investigations may extend to company premises, computers, accounting records and digital devices where the relevant procedural requirements are satisfied.

Preserve Digital Evidence

Do not delete emails, accounting databases, ERP records or corporate messaging histories.

Do Not Destroy Old Phones

They may contain evidence establishing who actually gave transaction instructions.

Foreign Investor Summoned by Police

Determine your procedural status and the allegations before providing a detailed explanation.

Do Not Ignore the Summons

A foreign investor should not assume that leaving the matter to an accountant or local business partner will resolve a criminal investigation.

Prepare From Documents, Not Memory

Substantial investments often involve transactions from several years earlier.

Do Not Guess

If you cannot remember the purpose of a EUR 750,000 transfer, examine the banking and corporate records before providing a definitive explanation.

Foreign-Language Documents

Investment agreements, bank statements and corporate records may be in English, Arabic, Russian, German or another language.

Preserve Originals

Where translation is required for Turkish proceedings, retain the original document together with the translated version.

Foreign Banking Evidence

Historical foreign bank statements can be particularly valuable for demonstrating source of funds.

Tax Records

Where relevant, tax documentation may corroborate the legitimate origin of investment wealth.

Can a Foreign Investor Be Detained?

Potentially, depending on the alleged offense, evidence and applicable criminal-procedure conditions. Foreign nationality alone should not determine criminal responsibility.

Risk of Flight May Become an Issue

Because the investor has substantial foreign connections, prosecutors may examine circumstances relevant to procedural measures. The defense should address the actual statutory conditions rather than assuming that foreign nationality automatically justifies detention.

Judicial Travel Ban

A prohibition on leaving Turkey may be imposed as a judicial-control measure where the applicable legal requirements are satisfied.

A Pending Investigation Does Not Automatically Prevent Departure

The existence of an investigation and the existence of a judicial travel restriction are different questions.

Do Not Attempt to Circumvent a Travel Ban

Where a valid judicial restriction exists, the appropriate response is to pursue available legal remedies.

Residence Permit Consequences

A criminal investigation does not automatically cancel a foreign investor’s residence permit.

Criminal Proceedings and Immigration Proceedings Are Separate

Nevertheless, serious criminal allegations or resulting judicial developments can potentially create immigration consequences that require separate assessment.

Investment-Based Residence or Citizenship Issues

Where the investor’s Turkish status depends on qualifying investment, criminal proceedings do not automatically erase the underlying investment. However, criminal, immigration and nationality consequences should be evaluated independently according to the facts.

Deportation Risk

A foreign investor should not assume either that deportation is automatic or that investment status provides immunity from immigration measures.

Evaluate Any Deportation Decision Separately

If an administrative immigration measure is issued, its legal basis, evidence and available challenge should be examined independently from the criminal defense.

What If the Foreign Investor Is Outside Turkey?

Do not assume that remaining abroad will cause the investigation to disappear. The procedural position, summons, representation possibilities and potential measures should be assessed before making travel decisions.

What If the Investor Needs to Enter Turkey?

Determine the status of the criminal proceedings and any relevant judicial or immigration restrictions before travel.

Business Continuity During the Investigation

A financial-crime investigation can damage an otherwise legitimate company even before any criminal liability is established.

Employee Salaries

Document payroll obligations affected by account restrictions.

Taxes and Social Security

Maintain records of statutory payments becoming due.

Suppliers

Identify essential suppliers whose non-payment threatens operations.

Loans

Document repayment obligations and potential defaults.

Commercial Contracts

Record penalties, termination rights and other consequences triggered by frozen funds.

Why Business Impact Matters

Where legally relevant, concrete evidence concerning the consequences of broad asset restrictions can form part of arguments concerning their continuing necessity and scope.

Do Not Circumvent a Freeze Through Another Company

Redirecting business revenue to a related company solely to evade a lawful restriction can create additional problems.

Do Not Transfer Assets to Relatives

Transactions undertaken after learning of an investigation can attract further scrutiny.

Do Not Backdate Contracts

Never manufacture a commercial explanation for an old transfer.

Do Not Create Fake Invoices

A fictitious invoice can transform an evidentiary problem into a much more serious legal problem.

Do Not Delete WhatsApp or Email Communications

Contemporaneous communications may actually establish the investor’s lack of knowledge.

Do Not Coordinate Statements With Other Suspects

The defense should be based on authentic evidence, not an agreed narrative.

Do Not Destroy Accounting Records

Preserve both physical and electronic records.

What Should Be Done in the First 24 Hours?

Identify the investigating authority, preserve bank statements and digital communications, determine whether accounts or assets have been restricted and stop any unnecessary movement of disputed funds.

What Should Be Done in the First 48 Hours?

Identify every transaction under suspicion, determine who controlled the relevant accounts and reconstruct where the money came from and where it ultimately went.

What Should Be Done in the First 72 Hours?

Collect shareholder agreements, board resolutions, banking mandates, contracts, invoices, accounting records, customs documents, foreign bank statements, tax documents, crypto histories and communications.

Prepare an Authority Matrix

For the relevant period record:

Person → Corporate Position → Banking Authority → Transaction Limit → Authentication Access → Actual Role.

Prepare a Source-of-Funds Matrix

Record:

Asset/Payment → Amount → Original Source → Intermediate Accounts → Turkish Destination → Supporting Documents.

Prepare an Asset Matrix

Record:

Asset → Owner → Acquisition Date → Acquisition Price → Funding Source → Current Restriction → Alleged Connection With Crime.

Prepare a Criminal Allegation Matrix

Record:

Alleged Offense → Disputed Transaction → Alleged Role → Prosecution Evidence → Defense Evidence → Missing Evidence.

Why This Structure Matters

Complex financial investigations are often won or lost on whether thousands of transactions can be converted into a coherent evidentiary narrative.

2026 Criminal Defense Strategy for Foreign Investors Accused of Financial Crime in Turkey

The defense should begin by separating investment activity from alleged criminal activity and corporate ownership from personal conduct. The investor should identify the exact criminal allegation, prosecutor file and disputed transactions before giving a detailed substantive explanation. Every questioned transfer should be reconstructed from its original source to its ultimate beneficiary. Source-of-funds and, where necessary, source-of-wealth documentation should be obtained from Turkey and abroad. Where a Turkish company is involved, banking authorization and corporate governance records should establish who actually controlled the transactions. Where fraud is alleged, the investigation should identify who communicated with victims and who provided payment instructions. Where money laundering is alleged, the lawful economic origin of the disputed assets should be demonstrated through objective financial records. Where cryptocurrency appears in the transaction chain, banking evidence should be connected with exchange histories and blockchain records. Any bank-account or asset restriction should be examined according to its actual legal basis, scope and procedural chronology. Foreign investors should separately assess detention, judicial travel-ban and immigration risks rather than assuming that one automatically follows from another. The practical roadmap is therefore: identify the investigation → determine your procedural status → identify the alleged offense → isolate disputed transactions → preserve banking and digital evidence → identify actual account controllers → trace every disputed payment → identify ultimate beneficiaries → establish source of funds → establish source of wealth where relevant → preserve corporate governance records → separate personal and company assets → preserve cryptocurrency evidence → obtain foreign financial records → review the legal basis of asset restrictions → challenge unsupported or excessive measures through the appropriate procedure → prepare documentary evidence before statements → monitor judicial travel restrictions → assess immigration consequences separately → maintain business-continuity evidence throughout the investigation.

Frequently Asked Questions

1. Can a foreign investor be prosecuted in Turkey because suspicious money entered their company account?

Potentially, but the transfer alone does not automatically establish personal criminal responsibility. Investigators should determine the investor’s knowledge, authority, conduct and relationship with the transaction.

2. Can MASAK freeze a foreign investor’s bank accounts?

Different AML and criminal-procedure mechanisms can affect transactions or assets. The exact authority and legal basis should therefore be identified rather than treating every restriction as the same type of “MASAK freeze.”

3. Can a foreign investor’s assets be seized during a money-laundering investigation?

Yes, where the statutory requirements are satisfied. Law No. 5549 Article 17 provides for seizure through the procedure connected with Article 128 of the Criminal Procedure Code in cases involving strong suspicion of money laundering or terrorism financing. (Masak)

4. Is a foreign shareholder automatically responsible for crimes committed through the company?

No. Share ownership alone does not establish personal participation. Actual management authority, knowledge, banking control, instructions and financial benefit should be examined.

5. How can an investor prove the lawful source of investment funds?

Evidence may include foreign and Turkish bank statements, company-sale agreements, dividend records, tax documents, property-sale agreements, shareholder loan agreements and corporate investment documentation.

6. Can cryptocurrency holdings be investigated?

Yes. Where crypto assets form part of the suspected financial trail, exchange accounts, wallet addresses, transaction histories and blockchain movements can become relevant evidence.

7. Can a foreign investor leave Turkey during a criminal investigation?

A pending investigation does not automatically prohibit departure. However, a judicial prohibition on leaving Turkey may be imposed where the statutory requirements for judicial control are satisfied.

8. Can a financial-crime investigation lead to residence permit cancellation or deportation?

Not automatically. Criminal proceedings and immigration proceedings require separate legal assessments, although serious criminal developments can potentially create immigration consequences.

9. What should a foreign investor do if company bank accounts are frozen?

The investor should determine who imposed the restriction, identify the investigation and disputed transactions, preserve financial records, establish the lawful source of legitimate company funds and examine the appropriate procedural remedy.

10. What should a foreign investor do immediately after learning about a financial-crime investigation?

Preserve evidence, identify the prosecutor file and alleged offense, avoid unnecessary movement of disputed assets, reconstruct the financial transactions and obtain the corporate and foreign banking records necessary to establish actual control and lawful source of funds.
