A will may describe a property by an outdated parcel number, refer to the same person under different names, or contain provisions in several documents that do not match. In such cases the first question is not whether the will is necessarily invalid. First, it is examined what the testator's validly declared intent was and which result it was meant to achieve. However, interpretation cannot be used to create a new bequest that does not appear in the text. 1 3
Short answer: When a will is interpreted, the whole text, the circumstances in which it was drawn up and lawful evidence that clarifies the testator's true intent are considered together. A manifest error in naming a person or thing may be corrected under TMK Article 504/2 where the true wish can be definitively established. Interpretation is not a general route to making a new will, curing every defect of form, or getting around the time limits for annulment and reduction. 1 3 6
What does interpreting a will mean?
Interpretation is the activity of determining the meaning and scope of the testator's last will. Whether a sentence names a particular beneficiary, which property it covers, or over what period a payment is to be made are examined within this scope. Because a will is a unilateral disposition mortis causa, the testator's intent is central. However, that intent must be linked to a disposition declared in the legally required form. 1 3
A division that the heirs today consider appropriate or fair cannot replace the intent declared in the past. The fact that the testator had good relations with a relative does not by itself show that the testator left the whole estate to that person. Likewise, a technical error in the use of a legal term does not always invalidate the bequest; the question of what the testator actually arranged must be answered from the whole text.
The purpose of interpretation and the protection of the reserved share are different things. A disposition may have a clear meaning and still infringe the reserved share. In that case, rather than rebuilding the distribution through interpretation, the appropriate claim and time limit are examined within the framework of Reduction Action and the Reserved Share. 1
The difference between interpretation, correction, annulment and supplementation
Clarifying an ambiguous expression
Explanatory interpretation establishes what the existing wording means. For example, if a will refers to "my house with the garden" and more than one property existed on the date of death, identifying which one is meant may require investigation. Land registry records, acquisition dates, address changes and the other provisions of the will may answer that question. The investigation does not, however, by itself remove the lack of any basis in the text for choosing a particular property. 3
Manifest error in identifying a person or thing
TMK Article 504/2 provides a special correction route for a manifest error in identifying a person or thing. Two elements matter together: there must be a clear error in the designation, and the testator's true wish must be definitively established. A similar name, an old block and parcel number or an address that changed later may start the inquiry; however, not every claimed material error automatically produces a correction. 1
Hypothetical example: A will describes as the testator's only summer house a property that has long been used as such. The address is correct, but one digit of the parcel number is wrong. If the title history and the other statements clearly identify the same property, correction may be arguable. By contrast, choosing the most valuable of three independent properties without any basis in the text would not correct a manifest error; it would create a new bequest.
Raising invalidity
Lack of capacity to dispose, a defect of intent, contrariness to law or public morals, and a defect of form are among the grounds for annulment under TMK Article 557. These grounds concern whether the document can legally stand rather than what it says. If the claimant's account in fact reveals a ground for annulment, the facts relied on and the outcome sought should be assessed, rather than the label attached to the claim. The grounds for annulment and their time limits are discussed in the article on the action to annul a will. 1
The limit of supplementary interpretation
How a circumstance not foreseen in the disposition should be handled may give rise to a debate on supplementary interpretation. Legal scholarship explains its limits and the requirement of a basis in the text in different ways. Öncü's examination of the theory of implied intent shows the tension between investigating the true intent and adherence to form. This debate does not give a judge the power to freely establish a new will on the testator's behalf. 7 For the preparation and amendment of a will, see the article on how a will is prepared.
| Issue | Primary legal assessment | What interpretation cannot do |
|---|---|---|
| More than one meaning for an expression | Reading the text and clarifying the intent | Forcing the preferred outcome into the text |
| Manifest error in identifying a person or property | Conditions of TMK Article 504/2 | Selecting a beneficiary or property before the true wish is established |
| Problem of capacity or form | TMK Articles 557–559 | Presuming a missing founding element of the act |
| Infringement of the reserved share | TMK Article 560 et seq. | Disabling the conditions of the reduction action |
| Gap arising later | Limits of supplementary interpretation | Making a new, valid testamentary disposition after death |
To what extent can evidence outside the text be used?
A will should not be treated as a single sentence. First the whole document, its annexes and the provisions that refer to one another are read. Then the property held at the time of drafting, family relationships, the place names used and the testator's customary expressions may be examined. However, the purpose of external evidence is to clarify the intent expressed in the will; it is not to construct an intent that was never declared. 3
Witnesses may explain a nickname the testator used or a name the testator gave to a particular house. By contrast, a witness's statement that "he wanted to leave her all his property" does not by itself create a comprehensive bequest that is absent from a validly formed text. The witness's direct knowledge, the date of the statement, the witness's relationship to the parties and consistency with other evidence are all examined. 2 3
Where private correspondence, letters or electronic records are to be used, attribution, integrity and lawful acquisition are important. Under Article 189/2 of the Code of Civil Procedure (HMK), evidence obtained unlawfully cannot be taken into account. Whether a message helps to understand the will is a different matter from whether it itself counts as a valid will or as an amendment. 2
Are old and new records of the same property different bequests?
A change in the land registry record over time, the implementation of a zoning plan or the establishment of floor ownership may create the impression that the will refers to more than one property. To resolve this, a connection between the old and new records must be established. Chain-of-title records, cadastral and zoning documents, lists of independent units and, where necessary, an on-site inspection and expert examination are used. Looking only at the current block and parcel number may not be sufficient. 2 3 The registration of the immovable property left under a will is explained in the article on registering title on the basis of a will.
In its decision dated December 18, 2013 (E. 2013/18683, K. 2013/18151), the 3rd Civil Chamber of the Court of Cassation (Yargıtay 3. Hukuk Dairesi) determined that two descriptions in a will related to the old and new records of the same property. It was held to be incorrect for the local court to bring within the will's scope a separate independent unit that did not appear in the text, on the view that the testator wished to leave all of his or her immovable property. 3
The practical importance of the decision is this: matching records is an exercise of interpretation and investigation; adding a third asset to the text is something different. The phrase "the testator's true intent" cannot serve as the justification for an extension that is not supported by the document and by other evidence. In a file of this kind, the textual basis for every property claimed should be shown separately.
What if there is more than one will, or conflicting provisions?
The first step is to determine the date, type and validity of every document. Under TMK Article 544, a later will replaces an earlier one unless it completes the earlier one in a manner that leaves no room for doubt. This rule should not be applied on the assumption that the later document is necessarily valid, or that every earlier sentence is deleted without any examination. The nature of the documents and their relationship to each other must be established first. 1
A later disposition that is incompatible with a specific bequest is also important under TMK Article 544. If property left under a will is later sold, it cannot be said that the sale price, or the new property acquired in its place, necessarily passes to the legatee. The text, any subsequent transactions and any contrary intent are examined. The finding that "the testator owns other property of the same value" does not by itself show that the will is directed at that property. 1
Where conflicts are apparent within a single will, the provisions are first read together. Can general and specific expressions be applied in harmony in terms of scope and time? Is one bequest an alternative to another, or an addition to it? Detaching one sentence from another without answering these questions may cause the true intent to be missed. An unresolvable uncertainty does not always result in the annulment of the whole will; the relevant provision and the legal ground are determined separately.
Appointment of an heir or bequest of a specific asset?
Even where the testator has written "heir" next to a person's name, the scope of the disposition is examined separately. TMK Article 516 treats a disposition that covers the whole estate or a stated share of it as the appointment of an heir. A bequest of a specific asset, however, may give rise to a different claim and a different succession arrangement. A single word does not always reveal the function of the whole text. 1
This distinction has practical consequences. An appointed heir is assessed through heirship status and the community of heirs (miras ortaklığı); a legatee of a specific asset generally has a personal claim against the person obliged to perform. If registration of title or delivery is needed, the party against whom the claim must be brought is determined separately. The opening proceedings before the civil court of peace are not a ruling that satisfies all of the legatee's claims. 1 The role of the person who carries out the will is explained in the article on the executor of a will.
Where a will states "I leave my house to my brother and the rest of my estate to my nephew", the legal positions of the different persons named should not be treated as identical. The distinctions between opening, notification and performance explained in Opening of a Will and Its Enforcement (Tenfiz) must be preserved after interpretation as well.
How are expressions containing conditions and time periods interpreted?
In expressions such as "during his education", "for as long as care continues" or "on condition that it is used as the family residence", the beginning, the end and the meaning of the event must be determined. Sometimes the dispute concerns the termination of the bequest; sometimes it concerns only the scope of a payment. Without distinguishing between a condition and a burden, it should not be assumed that a failure to comply automatically results in the loss of the right. 1
In its decision dated October 12, 2023 (E. 2022/2659, K. 2023/4689), the 7th Civil Chamber of the Court of Cassation examined an income arrangement tied to education. In the concrete file, the decision was based on the limits for the high school, bachelor's, master's and doctoral stages and on the submission of enrolment records, and it was upheld. This is an example of how an indefinite time expression is clarified within concrete circumstances. 4
The decision does not show that the word "education" necessarily covers the same stages in every will. A person who interrupts studies, starts a second programme or moves to another country may receive a different result under different wording. For each period claimed, the enrolment and time information should be shown; a general claim to education should not treat all periods as equal.
Does interpretation in favour of the will cure a defect of form?
Interpretation that keeps a will in force as far as possible aims to respect the testator's last intent. However, this approach does not mean that every form requirement is unimportant. There is a difference between recognizing, from the whole act, that one element of the transaction was carried out, and assuming a founding element that was never carried out at all. 1 6
In its decision dated May 6, 2026 (E. 2025/218, K. 2026/290), the Civil General Assembly of the Court of Cassation (Yargıtay Hukuk Genel Kurulu) discussed the witness statements in the official will of a person who cannot read or write. The majority accepted that, from the whole document, the act was carried out continuously before the witnesses and the statement was given in that manner, and interpreted the will in its favour. The decision of persistence (direnme kararı) that favoured annulment was quashed. 6
The decision also contains a dissenting view: the absence of a witness statement expressly confirming a particular matter was regarded as a defect of form under TMK Article 535/2. The majority did not adopt this approach. The decision should therefore not be presented as unanimous, nor as if it made every defect of form immaterial. The complete absence of an official officer or of the required witnesses is not the same matter as interpreting the whole text. 6
In preparing for this process, the route to follow is not to assume that a favourable interpretation will be made later, but to fulfil clearly the form requirements of the chosen type of will. A step such as preparing a handwritten will on a computer and then signing it cannot be made safe merely by arguing that the true intent is clear. 1
Changes in law or life circumstances over time
The date on which a will was drawn up, the date of the testator's death and the date on which the dispute is heard may all differ. Determining the applicable law and interpreting the intent expressed in the text are not the same process. For older wills in particular, it is examined together with transitional provisions such as Law No. 4722 which inheritance and reserved-share provisions apply by reference to which date. 9
Bağcı's examination shows the need for caution against the view that a change in legislation automatically redetermines an intent already declared in a will. The fact that the legal regime has changed does not mean that the testator is presumed to accept every consequence under the new law from an old sentence. Equally, applying the old law to every question without regard to the transitional provisions would be wrong. 8
Where a foreign state drew up the document, or the testator is a foreign national, the form, the applicable law and immovable property in Türkiye are assessed separately under Articles 7 and 20 of the Law No. 5718 on Private International and Procedural Law (MÖHUK). A dictionary equivalent of a foreign-language expression alone may not be sufficient. A reliable translation requires the meaning of the relevant legal concept and a connection to the original document. A translation error must not be confused with the testator's own error in designation. 10
Can a separate interpretation or declaratory action always be brought?
Interpretation of a will is often resolved within an enforcement, registration, delivery, annulment or reduction action. If a separate declaratory action is contemplated, present legal interest must be shown under HMK Article 106. Abstract curiosity, a dispute that may arise in the future, or a question that can already be resolved through another claim does not confer a right to bring an independent action. Purely factual matters likewise cannot by themselves be the subject of a declaratory action. 2
In its decision dated November 27, 2019 (E. 2019/1706, K. 2019/9441), the 3rd Civil Chamber of the Court of Cassation examined a new declaratory request concerning the scope of a will that had previously been the subject of an enforcement action. The chamber assessed the concrete result by the absence of present legal interest. This decision cannot be generalized to mean that all interpretation actions are barred or that res judicata always exists. 5
Res judicata is a separate examination. Under HMK Article 303, the parties, the cause of action and the outcome sought are compared. Not only the name of the earlier file but its pleadings, operative part and finality must be examined. The absence of legal interest and res judicata are not the same ground for rejection, and the correct distinction directly affects how a new application is prepared. 2
Which documents are needed to prepare a case?
| Document group | What it clarifies | Point to watch |
|---|---|---|
| Full copy of the will and the opening file | Text, date, notification and annexes | Not relying on a single selected page or an incomplete photocopy |
| Earlier and later dispositions | Supplementation, replacement or revocation | Examining the validity of each document separately |
| Title and cadastral history | Old and new records and the identity of the property | Not treating the same property as two different properties |
| Civil registry and corporate records | Identity of the beneficiary or the organization | Separating name similarity from succession |
| Lawfully obtained correspondence and witness information | Context of the disposition and the expressions used | Ensuring that external evidence does not create a disposition that is absent from the text |
| Earlier case files | Legal interest and res judicata | Comparing the scope of the judgment, the parties and the outcome sought |
Once the documents have been gathered, the disputed sentences should be marked one by one; for each sentence, the meaning proposed by each party, its textual basis and the supporting evidence should be indicated. This exercise produces a more concrete map of the dispute than a general request to the court for interpretation. The strongest explanation of the opposing side should also be assessed, rather than simply listing the favourable evidence. 2
Court, time limits, costs and enforcement of the decision
The court and jurisdiction depend on the legal protection sought. Opening a will is a procedure before the civil court of peace, whereas for contested property claims the competence of the civil court of first instance arises. For annulment and reduction, HMK Article 11 applies; for claims concerning the substance of an immovable property, Article 12 and other special provisions are assessed. Adding the heading "interpretation" to a petition does not change these rules. 1 2
There is no single general time limit for an interpretation claim. The periods of the main claim apply: for annulment, TMK Article 559; for reduction, Article 571; and for a claim based on a legacy, Article 602. The fact that nullity may always be raised as a defence under TMK Article 559/2 does not mean that an independent annulment or recovery claim whose time limit has passed can be brought under another name. 1 For conditional and burdensome expressions, see the article on conditions and burdens in a will.
Court fees and expenses also depend on the main claim, the value in dispute and the need for an inspection and expert evaluation. Historical matching of land registry records or the translation of a foreign document may require additional investigation. For this reason, no fixed total fee or precise end date can be stated. For appeals, the general time limits must be checked against the nature and value of the decision and its current finality rules; the two-week periods under HMK Articles 345 and 361 are assessed in connection with service. 2
After a decision, if registration, delivery or payment is required, it is checked whether the operative part achieves that step. Determining the meaning of an expression alone does not in every case produce the required performance or registration. For this reason, the claim should be framed from the outset so as to lead to a practically enforceable result.
Conclusion
Interpreting a will reduces uncertainty while preserving the limits of the last intent. The text, external evidence and the form of the disposition must be assessed together. Matching old records or correcting a manifest error in identification may be possible; a new bequest without any basis in the text cannot be created through interpretation. An application made without first determining the correct type of action, legal interest and time limit may end before the merits are discussed. This article is general information; the entire disposition and the relevant files must be examined separately.
Frequently Asked Questions
Is every ambiguity in a will a ground for annulment?
No. Some ambiguities can be resolved by interpretation. For annulment, the grounds in TMK Article 557 and the relevant action requirements are examined separately. 1 Detail: The difference between interpretation, correction, annulment and supplementation.
Does a will become invalid if a wrong parcel number is written in it?
Not automatically. Where a manifest error in identification exists and the testator's true wish can be definitively established, TMK Article 504/2 may apply. Examining the title history is important. 1 3 Detail: Are old and new records of the same property different bequests?.
Can a witness say that property not written in the will was left?
A witness can explain the context, but cannot by itself create a new bequest that has no basis in a validly formed text. The function of external evidence must be distinguished from the form of the disposition. 2 3 Detail: To what extent can evidence outside the text be used?.
Does a later will remove the whole of an earlier one?
TMK Article 544 provides that a later disposition replaces the earlier one; the case in which the later document completes the earlier one in a manner leaving no doubt is assessed separately. The validity and scope of the documents cannot be determined without examining them. 1 Detail: What if there is more than one will, or conflicting provisions?.
If a house left under a will is sold, does the sale price always go to the legatee?
No. The compatibility of the later transaction with the bequest, any contrary intent and the scope of the document are examined. The sale price or a new property acquired in its place must not be treated as an automatic substitute. 1 Detail: What if there is more than one will, or conflicting provisions?.
Is a person called "my heir" always an appointed heir?
A single word is not enough. The distinction between an appointment of the whole estate or a stated share of it and a bequest of a specific asset is made from the whole text. 1 Detail: Appointment of an heir or bequest of a specific asset?.
Does interpretation in favour of the will cure every defect of form?
No. The 2026 Civil General Assembly (HGK) decision assessed the transaction elements that were found to have been carried out within the whole document. It does not follow that founding elements that are entirely absent can always be completed by interpretation. 6 Detail: Does interpretation in favour of the will cure a defect of form?.
Is it compulsory to bring a separate interpretation action?
In most disputes, interpretation is carried out within the main claim. For a separate declaratory action, present legal interest and the other conditions of the action must be shown. 2 5 Detail: Can a separate interpretation or declaratory action always be brought?.
After the annulment period has passed, can the same result be sought under the name of interpretation?
The name of a claim does not change its time limit. If in substance annulment, reduction or the performance of a legacy claim is sought, the rules of that claim apply. The defence available at any time and an independent right to sue are separate matters. 1 Detail: Court, time limits, costs and enforcement of the decision.
Is a Turkish translation of a will written in a foreign language sufficient?
A translation may be necessary but does not resolve every problem. The original document, its form, the applicable law and the meaning of the concepts within that law must also be assessed. 10 Detail: Changes in law or life circumstances over time.
