Accidental Incorrect Information to an Insurer in Turkey | Foreign Policyholders 2026

What happens if a foreign policyholder accidentally gives incorrect information to an insurer in Turkey? Learn about disclosure duties, innocent mistakes, premium differences, claim reductions and insurance disputes.

A foreign policyholder who accidentally provides incorrect information to an insurance company in Turkey does not necessarily lose all insurance coverage or compensation rights.

The consequences depend on several factors, including what information was incorrect, whether the insurer specifically asked for it, whether the policyholder knew the correct information, whether the mistake was intentional or negligent, whether the insurer would have accepted the risk on different terms and whether the incorrect information is connected with the subsequent insured loss.

Turkish insurance law distinguishes between deliberate concealment and less serious disclosure failures. Therefore, an insurer should not automatically treat every inaccurate answer as insurance fraud or use every mistake as justification for rejecting the entire claim.

For foreign homeowners, investors and business owners, the most important step is to establish exactly how the incorrect information was provided and whether it materially affected the insurance risk.

1. What Kind of Incorrect Information Can Cause a Dispute?

Examples include incorrect information concerning:

• Property size;
• Building age;
• Construction type;
• Previous property damage;
• Previous insurance claims;
• Property use;
• Security systems;
• Fire-protection systems;
• Business activities;
• Machinery;
• Warehouse contents;
• Previous accidents;
• Value of insured property.

The consequences can differ substantially depending on the nature of the mistake.

2. An Accidental Error Is Not Automatically Fraud

This distinction is fundamental.

Compare:

Situation A: A foreign homeowner deliberately conceals a serious previous fire after being specifically asked about it.

Situation B: A foreign homeowner states that an apartment is 160 square metres because that figure appeared in documents received during the purchase, but the correct insurance measurement is 168 square metres.

The existence of incorrect information does not make these situations legally identical.

Intent, knowledge and materiality must be examined.

3. Determine What the Insurer Actually Asked

The insurance application should be obtained immediately.

Review:

• Proposal form;
• Questionnaire;
• Online application;
• Policy schedule;
• Agent communications;
• Emails;
• Messages.

The precise wording of the insurer’s question can be extremely important.

4. Was the Incorrect Fact Specifically Requested?

Suppose the insurer asks:

“Has this property suffered flood damage during the previous five years?”

The policyholder answers:

“No.”

A later investigation discovers an earlier flood.

The next questions should be:

• Did the policyholder know about it?
• Did the foreign owner own the property at the time?
• Was the previous damage disclosed during the purchase?
• Did the insurer have access to previous claim information?

The incorrect answer alone does not establish deliberate concealment.

5. Knowledge Is Critical

A foreign buyer may simply not know the complete history of a Turkish property.

For example, the previous owner may have failed to disclose:

• Previous flooding;
• Structural defects;
• Previous insurance claims;
• Water leakage;
• Fire damage.

The foreign policyholder’s actual knowledge should therefore be investigated.

6. Reconstruct How the Mistake Happened

Prepare a simple chronology:

Property purchased

→ documents received from seller

→ insurance application completed

→ policy issued

→ insured event occurred

→ insurer discovered discrepancy

This can help demonstrate whether the incorrect information resulted from an innocent mistake rather than deliberate concealment.

7. Who Completed the Insurance Form?

This is particularly important for foreign customers.

The application may have been completed by:

• The foreign policyholder;
• Insurance agent;
• Broker;
• Bank employee;
• Company employee;
• Representative.

Determine who actually typed or wrote the disputed answer.

8. Preserve Communications With the Insurance Agent

Keep:

• Emails;
• Messages;
• Documents sent to the agent;
• Draft applications;
• Questions and answers;
• Policy quotations.

These documents may show that the foreign customer supplied correct information but the application was completed incorrectly by another person.

9. Language Difficulties Can Be Relevant

A foreign policyholder may misunderstand a technical insurance question.

For example, there may be confusion between:

• Gross and net property area;
• Residential and mixed use;
• Renovation and structural alteration;
• Previous damage and previous insurance claim.

Language difficulty does not automatically eliminate legal responsibilities, but it may be relevant when determining how the mistake occurred and whether there was intentional concealment.

10. Correct the Information Promptly

If the mistake is discovered before any insured event occurs, the safest approach is generally to notify the insurer promptly in writing.

Explain:

• What information was incorrect;
• What the correct information is;
• How the mistake occurred;
• When it was discovered.

Do not wait for a future claim to reveal the discrepancy.

11. Do Not Attempt to Conceal the Original Mistake

A small accidental error can become a much more serious problem if the policyholder later attempts to hide it.

Never:

• Alter the original application;
• Backdate documents;
• Delete relevant communications;
• Create false invoices;
• Fabricate explanations.

Preserve the original record.

12. The Insurer May Reassess the Risk

If corrected information materially affects the insurance risk, the insurer may need to determine whether the policy would have been issued:

• At the same premium;
• At a higher premium;
• With different conditions;
• With an exclusion;
• Or at all.

The applicable legal consequences depend on the timing and circumstances.

13. A Premium Difference Can Be Important

Suppose:

Premium paid: TRY 25,000

Premium that would allegedly have applied with correct information: TRY 30,000

If the insurer relies on this difference after a claim, request the underlying calculation.

Ask:

• How was TRY 30,000 calculated?
• What underwriting factor changed?
• What tariff or risk criterion was used?
• Would the insurer really have issued the policy on those terms?

The insurer’s assertion should be capable of verification.

14. Complete Claim Rejection Is Not Automatically Appropriate

This is one of the most important issues.

An insurer should not simply reason:

Incorrect information → disclosure breach → zero compensation.

Turkish insurance law provides differentiated consequences depending on matters such as fault, materiality, premium consequences and the circumstances surrounding the insured event.

In appropriate circumstances, the issue may involve a proportional reduction rather than complete loss of compensation.

15. Ask Why the Insurer Is Rejecting the Entire Claim

If compensation is denied completely, request a written explanation addressing:

Why does this particular mistake justify total rejection?

Does the insurer allege intentional concealment?

What evidence establishes intent?

Would the insurer have refused the risk entirely?

Is the incorrect information related to the insured event?

These questions can significantly narrow the dispute.

16. Causation May Be Extremely Important

Consider two examples.

Example One

Incorrect information concerns previous minor water leakage.

The insured property later suffers an electrical fire.

Example Two

The insured fails to disclose a known serious electrical defect.

The subsequent fire originates from that electrical system.

The legal analysis may be very different.

17. Separate the Mistake From the Cause of Loss

Always prepare two separate analyses:

Disclosure Analysis

What information was incorrect and why?

Loss Analysis

What actually caused the insured event?

Do not allow the insurer to merge the two automatically.

18. Incorrect Property Size Is a Common Example

Foreign property owners may rely on:

• Sales advertisement;
• Title information;
• Developer documentation;
• Architectural documents;
• Agent statements.

If a later insurance measurement produces a different area, determine the reason for the discrepancy.

A measurement disagreement should not automatically be characterized as deliberate misrepresentation.

19. Incorrect Building Age Can Also Occur

Foreign buyers sometimes receive inconsistent information concerning:

• Construction date;
• Occupancy date;
• Renovation date;
• Building registration.

Preserve the documents relied upon when completing the insurance application.

They may demonstrate that the answer was given in good faith.

20. Property Use Can Create More Serious Problems

Suppose the policy states:

Residential property

but the property is actually being used commercially.

The insurer may argue that the incorrect classification affected the risk and premium.

Determine:

• When commercial use began;
• Whether it existed when the policy was issued;
• Whether the insurer knew;
• Whether the agent inspected the property;
• Whether commercial use affected the premium.

21. What If the Property Use Changed Later?

This should be distinguished from incorrect information provided when the insurance contract was originally formed.

For example:

Policy issued January: residential use.

Property converted to office in June.

Fire occurs in November.

That chronology raises a later change-of-risk issue rather than necessarily a false statement at policy inception.

22. Previous Claims Can Cause Disputes

An insurer may discover an earlier claim and argue that the foreign policyholder failed to disclose it.

Determine:

• Who made the previous claim;
• Whether the foreign owner owned the property then;
• Whether the current insurer knew about it;
• Whether the application specifically requested that information.

Ownership history can be crucial.

23. Foreign Business Owners Face Similar Risks

Commercial policies often require detailed information concerning:

• Business activities;
• Production;
• Stock;
• Machinery;
• Fire precautions;
• Security;
• Previous losses.

An innocent mistake in a commercial application can therefore become a significant issue after a major loss.

24. Example: Incorrect Warehouse Information

A foreign company states that a warehouse contains ordinary consumer products.

Later, the insurer alleges that a different category of goods was stored there.

The company should investigate:

• When the goods arrived;
• Whether they were present when insurance began;
• Whether the insurer inspected the warehouse;
• Whether the goods changed the risk;
• Whether the alleged discrepancy affected the loss.

25. The Insurer’s Prior Inspection May Matter

If the insurer inspected the property before issuing or renewing the policy, preserve:

• Inspection report;
• Photographs;
• Risk survey;
• Recommendations;
• Correspondence.

The insurer’s prior knowledge of the property’s actual condition can become highly relevant.

26. What If the Insurer Already Had the Correct Information?

Suppose the application contains an incorrect figure but the insurer’s own survey contains the correct figure.

That inconsistency should be highlighted.

The complete underwriting file may therefore matter more than the application form alone.

27. Renewal Policies Require Separate Examination

A policy may have been renewed repeatedly.

Ask:

• Was the same information copied automatically each year?
• Did the insurer conduct new inspections?
• Were updated documents requested?
• Was the alleged error known during previous renewals?

A long insurance relationship may provide important evidence.

28. Request the Underwriting File Where Appropriate

In a significant dispute, the insurer’s risk assessment can become important.

The central question may be:

Would the insurer genuinely have refused or materially altered this policy if the correct information had been supplied?

Objective underwriting evidence may help answer that question.

29. What If the Insurer Calls the Mistake “Fraud”?

Do not allow terminology to replace evidence.

Request identification of:

• False statement;
• Knowledge of falsity;
• Alleged intention;
• Evidence supporting the allegation.

An accidental error and deliberate insurance fraud are fundamentally different allegations.

30. Preserve Evidence Showing Good Faith

Useful evidence may include:

• Documents originally relied upon;
• Messages with the seller;
• Agent communications;
• Previous inspection;
• Purchase documents;
• Earlier property reports.

These materials may demonstrate why the foreign policyholder reasonably believed the information was correct.

31. Do Not Create a New Explanation After the Claim

The strongest explanation is usually one supported by contemporaneous documents.

For example:

“This is the document I received before purchasing the property, and this is the document I sent to the insurance agent.”

That is stronger than an unsupported explanation created months after the dispute began.

32. Ask for a Detailed Rejection or Reduction Calculation

If compensation is reduced, request:

• Total assessed loss;
• Original compensation;
• Percentage reduction;
• Premium difference;
• Legal basis;
• Contractual basis.

A percentage should not simply appear without explanation.

33. Prepare a Disclosure Comparison Table

Issue	Information Provided	Correct Information	Explanation
Property area	160 m²	168 m²	Seller document used
Building age	2015	2014	Purchase documents inconsistent
Previous flood	None known	2022 incident	Occurred before ownership
Property use	Residential	Residential	No discrepancy
Previous claim	None known	Previous owner’s claim	Policyholder unaware

This can clarify the dispute immediately.

34. Obtain Technical Evidence Where Necessary

Some alleged incorrect information involves technical matters.

An independent expert may be required for:

• Building age;
• Structural condition;
• Previous damage;
• Electrical systems;
• Fire protection;
• Machinery;
• Cause of loss.

Technical evidence can help separate an innocent factual mistake from a genuinely material undisclosed risk.

35. Obtain Financial Evidence for Commercial Claims

Foreign businesses should also preserve:

• Accounting records;
• Stock records;
• Asset registers;
• Purchase invoices;
• Financial statements.

The underlying amount of the claim must still be proven even if the disclosure dispute is successfully challenged.

36. Correct Information Before a Loss Whenever Possible

If a foreign policyholder discovers an error while the policy is active and no loss has occurred, prompt written correction can substantially improve the evidentiary position.

Keep proof that the insurer received the correction.

37. Do Not Rely Solely on Telephone Conversations

Important corrections should generally be documented.

After a telephone conversation, preserve written confirmation showing:

• Date;
• Information corrected;
• Documents supplied;
• Insurer response.

This prevents later disagreement over what was communicated.

38. What If the Insurer Offers Reduced Compensation?

Before accepting, determine:

• Why the reduction was made;
• Whether the calculation is correct;
• Whether accepting payment requires a release;
• Whether remaining rights are reserved.

A reduced payment should not automatically be treated as a fair resolution.

39. Be Careful With Settlement and Release Documents

A settlement may contain language waiving future claims.

Before signing, determine whether the payment settles:

• Only the disclosure dispute;
• Only part of the damage;
• Or every claim arising from the insured event.

This is especially important in high-value commercial losses.

40. Insurance Arbitration May Be Available

Depending on the insurer and applicable procedural requirements, insurance arbitration may provide a route for challenging a rejected or reduced claim.

The policyholder should preserve:

• Written application;
• Supporting documents;
• Insurer response;
• Technical reports;
• Compensation calculation.

41. Court Proceedings May Also Be Considered

Where appropriate, a foreign policyholder may pursue judicial remedies concerning a disputed insurance claim in Turkey.

High-value disputes can involve detailed examination of:

• Application documents;
• Underwriting evidence;
• Expert reports;
• Witness evidence;
• Premium calculations;
• Causation.

Early evidence preservation is therefore essential.

42. Do Not Allow Negotiations to Continue Indefinitely

Insurance claims are subject to legal deadlines.

Maintain a chronology showing:

Policy date

Discovery of mistake

Correction date

Loss date

Claim notification

Insurer decision

Objection

This helps protect against procedural problems.

Frequently Asked Questions

1. Does an accidental mistake automatically invalidate insurance in Turkey?

No. An accidental incorrect statement does not automatically mean that the policy or every compensation right disappears. The circumstances of the mistake and its legal significance must be examined.

2. Can the insurer reject the entire claim?

Potentially in circumstances where the applicable legal requirements justify that consequence, but complete rejection should not be assumed merely because some information was incorrect.

3. Can compensation be reduced instead?

Yes, depending on the circumstances, the applicable disclosure rules can make a proportional reduction relevant rather than complete rejection.

4. What if the foreign policyholder genuinely did not know the correct information?

Actual knowledge and the circumstances in which the information was obtained can be highly relevant. This commonly arises where previous property damage occurred before the foreign owner purchased the property.

5. What if the insurance agent made the mistake?

The application process should be reconstructed. Messages, emails, documents supplied to the agent and the original application can become critical evidence.

6. What if the mistake has nothing to do with the insurance claim?

The relationship between the incorrect information and the subsequent insured event can be highly significant when determining the legal consequences after the loss.

7. Should an error discovered before a claim be corrected?

Generally, prompt written notification to the insurer is prudent. The policyholder should preserve proof of exactly what was corrected and when.

8. What if the insurer says it would have charged a higher premium?

Request the calculation and underwriting basis showing what premium would actually have applied if the correct information had been provided.

9. Is an innocent mistake the same as insurance fraud?

No. An innocent or negligent error should not automatically be equated with intentional deception or fraud.

10. What should a foreign policyholder do if compensation is rejected?

Obtain the written decision, original application, complete policy and underwriting explanation, then examine knowledge, fault, materiality, premium difference and causation before deciding whether to challenge the decision.

Client-Focused Legal Support for Incorrect Insurance Information in Turkey

Foreign policyholders should not assume that an accidental mistake in an insurance application automatically destroys their right to compensation.

A proper analysis should answer:

What information was incorrect?

Was it specifically requested?

Did the policyholder know it was incorrect?

Who completed the application?

What documents did the foreign policyholder rely upon?

Did the insurer already know the correct information?

Would the correct information have changed the premium or the insurer’s decision to provide coverage?

Is the mistake connected with the subsequent insured event?

These issues can determine whether the insurer has a valid defence, whether compensation can be reduced or whether the policyholder can continue to seek the full insured amount.
