A transfer of immovable property made through fraud, a material mistake or duress of legal significance may be challenged by seeking the return of the title on the ground that one is not bound by the contract. This right is not unlimited. Under Article 39 of the Turkish Code of Obligations (TBK), it must be exercised within one year from the discovery of the mistake or fraud or, in the case of duress, from the moment the effect of the duress ceased. The starting point is not, in every case, the date of sale recorded in the land registry. [1]
"They deceived me" has a legal meaning only when it is explained who caused the defect of will and through which conduct. A later regret about the sale, non-payment of the price or deterioration of family relations is not always fraud, mistake or duress. The correct legal basis, the evidence and the calculation of time depend directly on this.
What is the difference between fraud, mistake and duress?
| Legal basis | Core issue | Start of the one-year period |
|---|---|---|
| Mistake (yanılma, hata) | A legally material false belief in forming the transaction | Discovery of the mistake |
| Fraud (aldatma, hile) | Deliberate misleading, or concealment of the truth where circumstances require disclosure | Discovery of the fraud |
| Duress (korkutma, ikrah) | A transaction made under the effect of a grave and imminent threat of harm | End of the effect of the duress |
The one-year period in this table should not be confused with the five-year outer limit for laesio enormis (gabin) or with the limitation period of a contractual claim. TBK Article 39 does not set out a general ten-year outer limit running from the sale for every case. In a specific dispute, the principle of good faith, special provisions and any separate monetary claims are also examined. [1]
Which misleading conduct may amount to fraud?
Intentional deception affecting the will to contract
Where the other party knowingly gives false information, shows a document contrary to the truth, or conceals an important matter it was bound to disclose, and the decision to contract is affected, fraud may arise. For example, where it is said that only a particular share will be transferred but the whole property is transferred, or where deliberate misleading about the true nature of the transaction is alleged, the claim must be made concrete.
For fraud under TBK Article 36, the deceived person's error does not have to be as material as under the mistake provisions. However, there must be a link between the deception and the conclusion of the contract. A lie about some other matter does not, by its mere existence, allow the land transfer to be annulled. [1]
Non-payment of the price later does not by itself show that fraud occurred when the transaction was concluded. Where it is claimed that there was no intention to pay from the outset, the conduct supporting that claim is examined. If there is only a breach of contract, a claim for the price, performance or other contract-specific remedies may come into play. For details, see the article on non-payment of the sale price after a land transfer.
Fraud by a third party and the other party's knowledge
Where the person who deceived is not the other party to the contract, it matters whether the counterparty knew or ought to have known of the deception at the time of the contract. For example, if a sale is made on a relative's instructions, the same annulment result does not follow in every case where the buyer was unaware of the deception. The knowledge requirement in TBK Article 36(2) must be linked to the concrete facts. [1]
For this reason, the person who engaged in the deceptive conduct, the buyer and any intermediary are shown separately. Their correspondence, prior relationship, money flows and transaction preparation are examined. Describing all of them merely as "acting together" can leave unclear which fact is attributed to whom.
When can a land transfer be annulled for mistake?
Material mistake is regulated in TBK Article 30 et seq. Mistakes of legal importance concerning the type or subject matter of the contract, the identity of the other party, or the scope of the performance are assessed. Not every calculation error or failure of an economic expectation prevents a party from being bound by the contract. For simple arithmetic errors, correction and annulment of the transaction have different consequences. [1]
Misidentification of the property or share
A person who believes they are transferring a particular parcel or share, but who carries out the transaction for a different property or share, may raise a material mistake depending on the circumstances. However, the parties' actual agreement, the declarations made in the transaction and the official deed are assessed together. That the title deed was not read does not by itself confirm every claim or eliminate every mistake claim.
A mistake claim must also be distinguished from the correction of a simple writing or identity error in the land registry. In one case the contractual will is in issue; in the other, the technical accuracy of the registry entry. The result sought and the route to be taken differ accordingly.
Mistake of motive and expectations about the future
Selling or buying a property because one expects its value to rise is, as a rule, that person's own economic expectation. For a mistake of motive to be treated as material, the conditions of TBK Article 32 are required: the motive must be regarded as the basis of the contract, it must be consistent with the rules of good faith, and it must be recognisable to the other party. [1]
For example, an assumption linked to a zoning expectation does not by itself give a right of annulment merely because it did not materialise later. How the parties discussed it, whether an existing fact was wrongly believed, and whether there was any deceptive statement are examined. If the mistaken party was at fault, the other party's damage may be assessed separately under TBK Article 35.
In what circumstances is annulment for duress sought?
The person subjected to duress must reasonably believe in a grave and imminent danger of harm to their own or their relatives' personal rights or property. The effect of the threat in the person's actual circumstances is assessed. Family pressure, quarrels or resentment, however unpleasant, do not on their own reach the level of duress under the law. [1]
Can a threat to use a legal right amount to duress?
As a rule, saying that a right or legal power will be exercised is not, on its own, unlawful pressure. However, if excessive advantage is obtained from the other party's difficult situation, duress may be assessed under TBK Article 38(2). Demanding payment of a debt and securing a disproportionate transfer of property under heavy pressure are not treated in the same way.
Duress by a third party is regulated differently from fraud. Under TBK Article 37, the person who was subjected to duress may claim not to be bound by the contract even if the counterparty did not know of the threat; however, where equity requires, a damages issue may arise against the unaware counterparty. The knowledge condition for third-party fraud should not be carried over unchanged to duress. [1]
The importance of concrete proof in a 2026 decision
In the decision of the Court of Cassation, 1st Civil Chamber (Yargıtay 1. Hukuk Dairesi), dated May 13, 2026, E.2025/5257, K.2026/3936, a transfer made on a claim of threat and the sale of the property to another person shortly afterwards were examined. Because the witness statements were not made concrete and contained contradictions, and the acquisition circumstances of the later buyer were assessed together, the dismissal of the action was upheld. [4]
The decision shows that a second sale shortly afterwards is not, by itself, evidence of bad faith. The outcome of a criminal investigation is also one of the elements in the file, but how the claim is proved in the civil action has its own importance. No conclusion can be drawn from this example that every threat case is unprovable or that a criminal conviction is necessary.
How is the one-year period protected?
Discovery and the end of the effect depend on the facts
In mistake or fraud, it must be explained when the relevant information was learned; in duress, which event ended the effect of the pressure. A registry record, a document in another case file, the discovery of a bank transaction, correspondence between the parties or a formal notice may play a role in this determination. A date written in a petition does not bind the court.
In a hypothetical example, the owner claims to have learned the true scope of the transfer on February 12, 2026. The one-year review is then conducted on the basis of that event. However, if there is a message from 2025 in which the owner clearly admitted the same situation, the starting point becomes disputed. This example is not a personal last-day calculation; it shows why the date must be supported by evidence.
Notice and action must be kept separate
TBK Article 39 requires that, within one year, the fact that one is not bound by the contract be notified, or that the thing given be claimed back. Exercising the right is not limited to filing an action. However, the content of the notice, its arrival at the other party, its scope and its timing must be provable. A vague complaint, or merely the revocation of a representative's mandate, does not in every file amount to a sufficient declaration of reclaiming. [1]
A properly served notice does not by itself change the land registry entry. If the other party will not return the property, the appropriate action is required. Claims for return or payment that may be raised after the notice, and their legal nature and time limits, are examined separately. The conclusion "I sent a notice, so I can now wait indefinitely" does not follow.
It cannot be assumed that a criminal complaint always suspends or protects the one-year right. While an investigation is ongoing, the timely exercise of the right concerning the defect of will and the need to protect the property are assessed separately.
What happens if fraud is confused with abuse of a power of attorney?
The owner may have granted the power of attorney through deception, while the attorney may have used that authority against the owner's interests. Different legal bases may exist together in the same event. The judge makes the legal characterisation, but does so within the concrete facts and the limits of the claim. Reducing all the events in a file to a one-year fraud period may be an error. [2]
In the decision of the Court of Cassation, 1st Civil Chamber, dated April 8, 2025, E.2023/3676, K.2025/1833, although claims were raised that the power of attorney had been obtained by fraud and then misused, the judgment dismissing the action solely on the basis that fraud was accepted and the time limit had passed was quashed. An investigation of the misuse of the power of attorney was ordered. [5]
This decision does not show that every time-barred fraud claim can be revived by renaming it. The elements of a different legal basis must actually exist in the concrete case and be properly put forward. For details, see the review of misuse of authority.
How should the evidence and the claim be prepared?
In claims of defect of will, proof by witness under Article 203 of the Code of Civil Procedure (HMK) is an important option. However, permitting a witness to testify does not mean that every statement proves the claim. What the person saw, which words they heard, and how these affected the decision to contract are examined. Correspondence, bank records, official deeds and documents on the preparation of the transaction should be submitted together. [2]
| Claim | Fact to be specified | Principal examples of evidence |
|---|---|---|
| Fraud | The false statement or concealed information and its link to the transaction | Correspondence, documents, witness present at the meeting |
| Material mistake | The difference between the transaction actually intended and the one carried out | Official deed, drafts, earlier agreement |
| Duress | The content, gravity, imminence and effect of the threat | Message, application record, direct witness |
| Exercise within time | Date of discovery or end of the effect, and the notice | Service records, notarised formal notice, case documents |
In an ordinary dispute, the action is brought before the civil court of first instance (asliye hukuk mahkemesi) where the property is located. The current owner, the holders of any mortgage and the addressees of any independent monetary claim are identified. The possibility that a later buyer is protected under Article 1023 of the Turkish Civil Code (TMK) is examined separately. An interim injunction is requested according to the standard of approximate proof and the risk of a further transfer. [2, 3]
Where a sum or damages is claimed together with the transfer of title, it must be explained which claim is primary and which is secondary, and the liability of each defendant. TBK Article 39 provides that the fact that the contract is deemed approved does not automatically extinguish the right to damages for fraud or duress. However, the conditions, proof and limitation of the damages claim are examined on their own terms. [1]
Court fees, on-site examination (keşif) and court-appointed expert (bilirkişi) costs vary according to the value of the claim and the need for investigation. The appeal routes, notification, monetary thresholds and the nature of the decision matter. Enforcement of the operative part of a judgment on title requires finality. A claim properly framed from the outset makes it easier to obtain an enforceable decision at the end of the proceedings. [2]

Conclusion
In fraud, mistake and duress, the recovery of title depends on the concrete event affecting the will, the correct starting date and the timely exercise of the right being established together. Fraud and a breach of contract must be distinguished from material mistake and economic regret, and ordinary family pressure from duress. A definitive result should not be expected from the first event alone, without examining the chain of title and any subsequent rights holders.
Frequently Asked Questions
In fraud, does the one year run from the date of sale?
As a rule, it runs from the discovery of the fraud. The fact and the document that support the discovery date are important.
Is sending a formal notice enough?
A notice that is clear, timely and has reached the addressee may be important for exercising the right. Agreement or an action may still be needed to recover the title in practice.
Can one wait until the criminal investigation ends?
It cannot be assumed that waiting automatically preserves the time limit. Exercising the one-year right and the need for interim protection must be assessed independently.
If the sale price is not paid, is there fraud?
Not always. Initial deceptive conduct must be distinguished from the later non-payment of the debt.
A relative deceived me and the buyer was unaware: what happens?
In the case of deception by a third party, whether the buyer knew or ought to have known of the deception under TBK Article 36(2) is important. Duress has separate rules.
Can a witness statement be used?
In claims of defect of will, proof by witness is available. The statement must be concrete, direct and consistent with the other evidence.
Is a later increase in the value of the house a ground for annulment?
Not by itself. The conditions of a separate legal ground, such as material mistake, fraud or laesio enormis (gabin), must exist.
If one year passes, does the claim for compensation necessarily end too?
For fraud and duress, TBK Article 39 separately preserves the right to damages. The legal basis of the damages claim and its own limitation period must be examined.
