I Gave Someone My IBAN in Turkey and Was Accused of Fraud: Criminal Liability Explained — 2026 Guide

Did you give someone your Turkish IBAN and later become accused of fraud? Learn when sharing an IBAN can lead to criminal liability, aggravated fraud allegations, account freezes, police questioning, digital evidence and defense strategies for foreigners in Turkey in 2026.

A foreigner living, studying, working or doing business in Turkey may give their Turkish IBAN to a friend, colleague, employer, customer or online acquaintance without initially believing that anything illegal is happening.

Weeks or months later, the foreigner may receive a call from the police or prosecutor and discover that money obtained from an alleged fraud was transferred to that bank account.

The immediate question is usually:

“Can I be convicted of fraud simply because I gave someone my IBAN?”

The answer requires a careful examination of the individual facts.

Giving someone an IBAN or being the registered owner of the receiving bank account can be highly important evidence, but criminal responsibility should not automatically be inferred solely from account ownership. Investigators should examine why the IBAN was provided, what the account holder knew, who controlled the account, what happened to the money, whether the account holder received a benefit and whether there is evidence of intentional participation in the alleged fraud.

This issue is particularly important in 2026. Turkish prosecutorial authorities have repeatedly warned that bank accounts and IBAN numbers are being obtained from students, job seekers and other individuals through promises of commissions, temporary account use or “easy money” and then used in fraud schemes.

Why Can Sharing an IBAN Lead to a Fraud Investigation?

Suppose a foreign student gives a friend their IBAN.

The friend says:

“My bank account is temporarily unavailable. A customer will send money to you. When it arrives, send it to me.”

A payment of 100,000 TRY arrives.

The foreigner transfers 95,000 TRY to the friend’s account and keeps 5,000 TRY.

Several weeks later, police contact the foreigner.

The original sender claims that the money was obtained through online fraud.

Investigators now see a financial trail:

Victim → Foreigner’s Turkish bank account → Third person

Because the foreigner’s bank account is directly visible in the transaction chain, the foreigner may become a suspect.

But that transaction chain does not answer every criminal-law question.

Investigators still need to determine the foreigner’s actual role.

Is Sharing an IBAN Itself Enough to Prove Fraud?

Not necessarily.

There is an important difference between:

providing an IBAN

and

knowingly participating in a fraudulent scheme.

The account holder’s knowledge, intent and conduct must be examined in light of the offence alleged.

The Constitutional Court’s explanation of the presumption of innocence emphasizes that evidentiary presumptions must not automatically transform an accused person into someone treated as guilty and that the accused must have a meaningful opportunity to challenge the allegation.

Therefore, the evidentiary analysis should not stop at:

“The account belongs to you.”

It should continue with:

“Why was your account used, what did you know, what did you do, and what evidence proves your individual involvement?”

Why Are Turkish Prosecutors Warning About IBAN Sharing in 2026?

Account-lending schemes have become an important enforcement issue.

Official prosecutorial warnings published in 2026 describe arrangements where individuals are approached with statements such as:

• “We will only use your account temporarily.”
• “Money will only enter and leave.”
• “You will receive a commission.”
• “You will have no responsibility.”
• “Just give us your IBAN.”

Authorities warn that these accounts may subsequently be used in aggravated fraud, money laundering and other criminal activity.

Another 2026 prosecutorial warning states that IBAN numbers rented or provided to third parties are frequently encountered in investigations involving technology-enabled fraud.

For foreigners in Turkey, these warnings should be taken seriously.

Account Ownership Does Not Answer Who Committed the Fraud

Consider a more complicated example.

Person A contacts the victim.

Person A uses a fake online advertisement.

The victim transfers money to an account belonging to Person B.

Person C has Person B’s bank card.

Person C withdraws the money.

Person D receives the cash.

The fact that Person B owns the receiving account is important.

But the investigation should determine separately:

• Who deceived the victim?
• Who supplied the IBAN?
• Who controlled the account?
• Who transferred the money?
• Who withdrew it?
• Who ultimately benefited?
• What did each person know?

Individual criminal responsibility cannot properly be determined merely by identifying the name printed on the bank account.

What If I Only Gave My IBAN?

This is one of the most common defenses.

The important question becomes:

Why did you give the IBAN?

If someone asked:

“Send me your IBAN so I can repay the 5,000 TRY I owe you.”

that is factually different from:

“Let me use your bank account for one month. I will pay you 10% of everything that passes through it.”

The second scenario creates much stronger grounds for investigative scrutiny.

Context matters.

What If I Never Spoke to the Fraud Victim?

This can be significant, but it is not necessarily decisive by itself.

Investigators should determine who actually communicated with the victim.

Relevant evidence may include:

• Telephone records
• WhatsApp messages
• Telegram messages
• Social-media accounts
• Email
• IP records
• Seized phones
• Voice recordings
• Digital forensic evidence

If another person carried out every deceptive communication while the account holder had no contact with the victim, that fact should be incorporated into the defense analysis.

What If the Victim Was Given My IBAN by Someone Else?

Preserve evidence showing this.

For example, the victim may have received your IBAN through:

• WhatsApp
• Telegram
• Instagram
• A fake website
• A telephone call
• An online marketplace

Investigators should determine who actually sent the IBAN to the victim.

The fact that the IBAN belongs to you does not necessarily prove that you transmitted it to the victim.

Criminal Intent Is a Central Issue

Fraud is not established merely by demonstrating that money moved through a bank account.

The prosecution must establish the legally required elements of the offence attributed to the accused.

Therefore, the investigation may need to distinguish between:

Knowing participation

and

Being deceived into providing an account.

For example, a foreigner may genuinely believe that the incoming payment represents:

• A customer’s payment
• Repayment of a debt
• Salary
• Freelance income
• Payment for goods
• A legitimate business transaction

Contemporaneous evidence explaining what the account holder believed can be extremely important.

What Evidence Can Show What I Knew?

Messages are often critical.

Preserve conversations showing:

• Why the IBAN was requested
• What explanation was provided
• Whether a commission was offered
• Whether you questioned the transaction
• Whether you were told the payment was legitimate
• What you did after discovering the allegation

The complete conversation is usually more useful than isolated screenshots.

Do Not Delete WhatsApp Messages

Suppose the person who used your IBAN wrote:

“This is payment from my customer for a computer I sold.”

That message may become important to your explanation of what you believed when the money arrived.

Deleting the conversation could destroy potentially exculpatory evidence.

Preserve the original device and the complete communication where possible.

What If I Received a Commission?

This creates a more difficult factual situation.

Official Turkish warnings specifically identify commission-based account arrangements as a major risk factor.

Investigators may ask:

• Why were you paid?
• How much were you paid?
• Was the payment proportional to the transferred money?
• How many times did you do this?
• Did you know the source of the funds?
• Did you know the people sending the money?
• Did you question why another person needed your account?

Receiving a commission does not eliminate the need to prove the charged offence, but it can become significant evidence when combined with other circumstances.

What If I Was Offered a Fake Job?

This is increasingly important.

A foreigner may receive an online job offer:

“We are an international payment company. You will receive customer payments into your Turkish bank account, forward them to our company and keep 5%.”

The supposed company may actually be using the foreigner as an intermediary.

Official 2026 prosecutorial warnings specifically identify students and job seekers among people targeted by account-use schemes.

If you were recruited through an alleged job, preserve:

• Job advertisement
• Website
• Emails
• Employment agreement
• WhatsApp messages
• Recruiter’s telephone number
• Identity documents they sent
• Payment instructions

These records may help establish how you became involved.

What If I Gave Someone My Bank Card and Password?

This creates substantially greater risk than merely providing an IBAN.

Investigators will likely ask:

• Why did you provide the card?
• Why did you provide the PIN?
• Did the other person have mobile banking access?
• For how long?
• Did you receive payment?
• Did you know money would be deposited?
• Did you monitor the transactions?

The defense should identify exactly who physically and digitally controlled the account.

Account Ownership and Actual Account Control Are Different

A bank account may legally belong to one person while another person actually operates it.

Potentially relevant technical evidence may include:

• Mobile banking login information
• Device information
• Authentication records
• Security notifications
• ATM CCTV
• Bank card transactions
• Telephone records

The question is not only:

“Whose account was it?”

It can also be:

“Who actually used it?”

ATM CCTV Can Be Important

Suppose fraud proceeds enter your account.

Ten minutes later, someone withdraws the money from an ATM.

If you deny making the withdrawal, CCTV may become important evidence.

Preservation can be time-sensitive because surveillance recordings may eventually be overwritten.

The defense should therefore identify relevant ATM locations, dates and times as early as possible.

What If I Personally Withdrew the Money?

That fact will likely receive close scrutiny.

Investigators may ask:

• Who instructed you to withdraw it?
• Who received the cash?
• Where did you meet?
• Did you keep any money?
• Why was cash required?
• Are there messages confirming the instruction?

Preserve the entire communication.

What If I Transferred the Money to Another IBAN?

The outgoing transaction should be documented.

Create a timeline:

Money received → instruction received → outgoing transfer → recipient → amount → time.

If someone instructed you to make the transfer, preserve those instructions.

What If I Converted the Money Into Cryptocurrency?

This can significantly expand the investigation.

Authorities may examine:

• Cryptocurrency exchange accounts
• Wallet addresses
• Transaction hashes
• Bank-to-exchange transfers
• Withdrawal records

The key questions remain who controlled the relevant accounts and what each participant knew.

Could I Be Accused of Aggravated Fraud?

Potentially.

Where alleged fraud involves information systems, banking infrastructure or other circumstances listed in the aggravated-fraud provisions, prosecutors may investigate the conduct under Article 158 of the Turkish Criminal Code.

A March 2026 prosecution announcement described an alleged scheme in which suspects impersonated bank employees, obtained verification codes and transferred victims’ money through different accounts. Prosecutors stated that victim statements, bank movements, communications records and digital evidence were evaluated together before charges were brought under Article 158/1-l.

This demonstrates why the complete evidentiary picture matters.

Could I Be Treated as an Accomplice?

Depending on the facts and evidence, investigators may examine whether the account holder intentionally facilitated the offence.

The distinction between an innocent intermediary and a person who knowingly assists criminal activity can therefore become central.

Evidence relevant to this question may include:

• Prior communications
• Repeated transactions
• Commission payments
• Relationship with the principal suspect
• Knowledge of the scheme
• Conduct after receiving the money
• Attempts to conceal transactions

There is no responsible way to determine accomplice liability solely from the statement:

“The money passed through your account.”

Could Money-Laundering Allegations Also Arise?

Depending on the circumstances, yes.

Official 2026 prosecutorial warnings specifically identify both aggravated fraud and laundering of criminal proceeds as potential risks associated with third-party account use.

Risk may increase where money is rapidly:

• Split among multiple accounts
• Withdrawn in cash
• Converted into cryptocurrency
• Sent abroad
• Moved through multiple intermediaries

The particular offence and individual criminal responsibility must nevertheless be established from the evidence.

There Is Also a Separate Risk Under Anti-Money-Laundering Legislation

Account-sharing can create legal issues beyond fraud.

Official government guidance has warned that where a person conducts a transaction in their own name but on behalf of another person, failure to notify the relevant financial institution in writing may engage Article 15 of Law No. 5549.

This is another reason why allowing another person to use a personal account should not be treated as an informal favor without legal consequences.

What If My Bank Account Is Frozen?

An account connected to alleged fraud may become subject to restrictions.

First determine:

• Who imposed the restriction?
• Is the entire account blocked?
• Is only the disputed amount blocked?
• Is there a criminal investigation?
• What is the investigation number?
• Is there a prosecutor or judicial decision?
• Is the bank applying its own compliance procedures?

Different restrictions may require different legal responses.

Does a Frozen Bank Account Mean I Am Guilty?

No.

A protective or investigative measure is not the same as a final criminal conviction.

The Constitutional Court emphasizes that a person facing a criminal accusation must be treated as innocent until guilt is established through the required judicial process.

Can Police Call Me for a Statement?

Yes.

If alleged fraud proceeds were transferred to your account, police or prosecutors may seek your statement.

Typical questions include:

• Who asked for your IBAN?
• Did you know the victim?
• Why did the money enter your account?
• Who controlled your mobile banking?
• Who transferred the money afterward?
• Who withdrew the cash?
• Did you receive a commission?
• Had this happened before?

Understanding the transaction history before giving speculative answers can be important.

“I Don’t Remember” Is Better Than Inventing an Explanation

A transaction may have occurred months before the police contact you.

Do not guess merely because you feel pressured to provide an immediate explanation.

An invented explanation may later conflict with objective records.

Review:

• Bank statements
• Messages
• Emails
• Transaction descriptions
• Relevant contracts

before reconstructing the event.

Can Police Seize My Phone?

A phone may become important evidence in an online-fraud investigation.

It may contain:

• WhatsApp conversations
• Telegram messages
• Banking applications
• Emails
• Cryptocurrency applications
• Social-media accounts
• Security notifications

The legality, scope and method of any digital examination should be evaluated under the criminal-procedure rules applicable to the investigation.

Do not delete potentially relevant material after learning about the investigation.

What If Another Person Used My Phone?

This should be supported with evidence where possible.

Investigators may examine:

• Device possession
• Account logins
• Application activity
• Communications
• Other devices
• Witnesses

Ownership of the phone is relevant, but ownership does not necessarily resolve who performed every digital action on it.

IP Address Evidence May Also Be Used

Investigators may obtain IP-related information concerning:

• Online accounts
• Banking sessions
• Websites
• Social-media activity

An IP address can connect activity to a technical internet connection.

It does not automatically identify the human user.

Shared Wi-Fi, corporate networks, dynamic allocation, CGNAT and other technical factors can affect attribution.

What If I Was Abroad When the Fraud Happened?

Preserve location evidence immediately.

Useful records may include:

• Passport movements
• Flight tickets
• Hotel records
• Foreign bank-card transactions
• Workplace attendance
• Location records

Physical absence does not necessarily resolve every allegation involving an online account, but it may be highly relevant to particular acts such as ATM withdrawals or physical meetings.

Foreign Employees Should Preserve Employment Evidence

If your employer or colleague asked you to receive money, preserve:

• Employment contract
• Salary records
• Internal messages
• Emails
• Instructions
• Company documents

Do not assume that an instruction from a supervisor automatically makes the transaction lawful.

But evidence showing what you were instructed to do may be highly relevant to your state of knowledge.

Foreign Business Owners Should Preserve Commercial Documents

Sometimes a fraud complaint arises from what the account holder believed was a genuine commercial transaction.

Preserve:

• Contracts
• Invoices
• Purchase orders
• Shipping records
• Customer correspondence
• Accounting records

Not every failed transaction or disputed payment automatically establishes criminal fraud.

Commercial Dispute or Fraud?

This distinction can become important.

A person may send money for goods that are delivered late or not delivered because of a genuine commercial failure.

That does not automatically establish that the recipient had fraudulent intent from the beginning.

The investigation should examine the actual representations, circumstances and intent rather than treating every contractual failure as criminal fraud.

Repeated Transactions Can Change the Evidentiary Picture

One unexplained transfer and fifty similar transfers are factually different.

Investigators may examine:

• Number of transactions
• Number of victims
• Total amount
• Repeated commission payments
• Repeated withdrawals
• Transfers to the same suspects

Patterns can be used to assess whether the account holder’s explanation is credible.

A 2026 Court of Cassation Decision Shows Why Complete Investigation Matters

In February 2026, the Court of Cassation overturned an aggravated-fraud conviction because further investigation was necessary concerning banking information, a disputed cheque, handwriting and signature evidence, and the underlying commercial relationship.

The Court stated, in substance, that the factual truth needed to be established without unresolved doubt before the defendant’s legal position could properly be determined.

Although that case concerned different factual allegations, the broader evidentiary lesson is relevant to IBAN cases:

Criminal responsibility should be determined after the relevant financial, documentary and technical evidence has been adequately investigated.

What Evidence Should Be Preserved?

If you gave someone your IBAN and later became accused of fraud, preserve:

• Complete bank statements
• Incoming transfer records
• Outgoing transfer records
• WhatsApp conversations
• Telegram conversations
• SMS messages
• Emails
• Job advertisements
• Employment documents
• Commercial contracts
• Invoices
• Security alerts
• ATM information
• Cryptocurrency records
• Travel records

Do not selectively preserve only evidence that appears favorable.

The complete chronology is usually more persuasive.

Do Not Delete Evidence

Do not:

• Delete WhatsApp
• Delete Telegram
• Factory-reset the phone
• Delete banking applications to conceal activity
• Delete emails
• Close digital accounts to destroy records
• Destroy bank cards

Some of the evidence you delete may actually support your defense.

Do Not Ask Another Suspect to Delete Messages

This can create additional problems.

Do not coordinate destruction of evidence or attempt to create a false version of events.

Preserve the existing evidence and reconstruct the actual transaction.

Should I Contact the Fraud Victim?

Exercise caution.

An account holder who suddenly discovers a criminal complaint may want to explain the situation directly.

But poorly worded communications may later be interpreted as:

• Admission
• Pressure
• Threat
• Attempt to influence testimony

Legal advice may be appropriate before contacting the complainant.

What If I Returned the Money?

Repayment can be legally relevant in fraud cases, but its effect depends on the circumstances, timing, applicable offence and procedural stage.

It should not automatically be assumed that repayment ends the investigation.

Likewise, returning money should not involve sending funds to an unrelated account merely because another person instructs you to do so.

First 24 Hours After Learning About the Investigation

A foreigner accused because they shared an IBAN should promptly:

1. Obtain the relevant bank statements.
2. Identify every disputed transaction.
3. Preserve all communications.
4. Identify who requested the IBAN.
5. Record why the IBAN was provided.
6. Determine who controlled the bank account.
7. Determine who had the bank card.
8. Preserve mobile-banking security records.
9. Identify who withdrew or transferred the money.
10. Preserve ATM information where relevant.
11. Preserve employment or commercial documents.
12. Preserve evidence of any fake job or deception.
13. Do not delete digital evidence.
14. Do not coordinate statements with other suspects.
15. Obtain legal advice before providing speculative explanations about transactions you do not understand.

20 Questions for an IBAN Fraud Defense

A proper defense should examine:

1. Who asked for the IBAN?
2. Why did they say they needed it?
3. When was it provided?
4. Did the accused know the victim?
5. Who communicated with the victim?
6. Who sent the IBAN to the victim?
7. How much money entered the account?
8. Was the payment expected?
9. What did the account holder believe the payment represented?
10. Who controlled mobile banking?
11. Who had the bank card?
12. Who performed the outgoing transfer?
13. Who withdrew the cash?
14. Was ATM CCTV available?
15. Was a commission paid?
16. Were there previous similar transactions?
17. Did the account holder receive any ultimate financial benefit?
18. Was the account holder recruited through a fake job or deception?
19. What do the digital communications actually show?
20. What objective evidence establishes knowledge and intentional participation?

2026 Current Legal Position

Third-party use of bank accounts and IBAN numbers is receiving significant attention from Turkish enforcement authorities in 2026.

Official prosecutorial warnings describe schemes targeting students, job seekers and other individuals with promises of easy income, commissions or temporary account use. Authorities warn that these accounts may then become part of aggravated-fraud and money-laundering investigations.

Recent 2026 investigations also demonstrate that prosecutors may evaluate banking transactions, communications records and digital evidence together when determining individual participation in sophisticated fraud schemes.

At the same time, the presumption of innocence remains fundamental. An evidentiary presumption should not automatically turn an accused account holder into a guilty person without an effective opportunity to challenge the accusation.

For a foreigner accused after sharing a Turkish IBAN, the key evidentiary chain should therefore be examined carefully:

IBAN ownership → reason for sharing → victim communication → incoming payment → actual account control → movement of money → financial benefit → knowledge → intent → individual participation.

The fact that your name appears on the receiving account can begin the investigation.

It does not, by itself, answer every question necessary to determine criminal liability.

Frequently Asked Questions

1. I gave someone my IBAN in Turkey. Am I automatically guilty of fraud?

No automatic conclusion should be based solely on providing an IBAN. Investigators should examine your knowledge, intent, account control, conduct and relationship to the alleged fraud.

2. What if I did not know the money came from fraud?

Your knowledge is a critical factual issue. Preserve all messages and documents showing what you were told and what you believed the payment represented.

3. What if my friend used my account?

Preserve the complete conversation with that person and evidence concerning who controlled the card and mobile banking. Investigators may examine whether you knowingly allowed the account to be used for criminal activity.

4. Can I be accused even if I never spoke to the victim?

Yes, an investigation can still occur. However, the fact that another person carried out the alleged deception may be highly relevant when determining your individual role.

5. What if I received a commission for allowing someone to use my account?

Commission payments can increase investigative scrutiny. Official 2026 warnings specifically identify paid account-use arrangements as a serious fraud and money-laundering risk.

6. Can my Turkish bank account be frozen?

Potentially. If this happens, determine the authority, legal basis, scope of the restriction and whether a criminal investigation exists.

7. Can police seize my phone because I shared my IBAN?

A phone may become relevant where investigators believe it contains communications or banking evidence. Any forensic examination should be assessed under the applicable criminal-procedure rules.

8. What if someone used my bank card to withdraw the fraud money?

Preserve messages and identify the ATM, date and exact time. CCTV and banking records may help determine who physically performed the withdrawal.

9. Should I delete messages with the person who used my IBAN?

No. Those messages may be among the most important pieces of evidence concerning what you knew and why you allowed the account to be used.

10. What should I do immediately after learning that I am accused?

Preserve your bank statements and communications, reconstruct the complete transaction timeline, identify who controlled the account and obtain legal advice before making speculative statements about transactions you do not fully understand.

Criminal Defense for Foreigners Accused After Sharing an IBAN in Turkey

An IBAN fraud investigation can quickly expand beyond a single bank transfer.

Police and prosecutors may examine bank accounts, mobile phones, WhatsApp conversations, ATM footage, IP records, cryptocurrency transactions, telephone records and relationships with other suspects.

The defense should therefore go beyond the simple question:

“Whose name is on the bank account?”

The more important questions are:

Why was the IBAN shared? Who deceived the victim? Who actually controlled the account? Who moved the money? What did the account holder know? Who ultimately benefited?
