1. What Is Inheritance Law?
Inheritance law is the branch of law that governs how a deceased person's material and non-material assets are transferred to their rightful successors. Estate division is the aspect of this field most often encountered in practice — and the one most prone to dispute.
The Turkish Civil Code sets out detailed rules covering the transfer of ownership, receivables, and debts. Three core principles run through this area of law: protection of heirs' reserved shares, respect for the deceased's last wishes, and the principle that the estate is indivisible until formally distributed. Distribution is primarily based on a statutory ranking system tied to kinship, though the deceased may modify this order within certain limits through a will or an inheritance contract.
2. Legal Heirs and Appointed Heirs
Under Turkish law, two categories of persons may hold rights over the estate in an estate division:
- Legal heir: A status that arises directly from the law upon the deceased's death, independent of the deceased's will. It is regulated under Articles 495–501 of the Turkish Civil Code. Legal heirs are the deceased's blood relatives, adopted children, their descendants, and the surviving spouse.
- Appointed heir: A person who becomes an heir because the deceased, exercising their own free will through a will or inheritance contract, left all or part of their estate to a specific person or institution (such as a foundation or association).
The rise in recent years of disputes over "asset-hiding to defeat inheritance" (mirastan mal kaçırma) claims highlights how important the boundaries between these two categories — and the protection of reserved shares — have become in practice.
3. The Parentela (Class) System and Its Core Principles
The Turkish Civil Code bases the inheritance rights of blood relatives on the parentela system (also called the class or degree system). Under this system, a three-tier structure comes into play upon the deceased's death; to qualify as a legal heir, a person must belong to one of these three parentelas.
The system's core features can be summarized as follows:
- The presence of an heir in an earlier parentela excludes the next parentela from inheriting. For example, if there are descendants (children) in the first degree, the deceased's parents in the second degree receive no share.
- Within the same parentela, an heir in an earlier rank excludes an heir in a later rank.
- As long as the head of a parentela (or "root") is alive, that person's own descendants cannot inherit.
4. Heirs by Parentela
Estate division always begins with the first degree; if there are no heirs at that level, the process moves to the second and then the third degree. The surviving spouse inherits alongside whichever degree is entitled to inherit, receiving a share determined by that degree.
4.1 First-Degree (Parentela) Heirs
The deceased's descendants — children, grandchildren, and all their issue — are first-degree heirs. The children are considered the heads of this parentela and inherit in equal shares. If a child predeceases the parent, that child's share passes by right of representation to their own children (the deceased's grandchildren); the predeceased child's spouse does not benefit from this share.
Example: When deceased A dies, the children C and D of A's predeceased son B inherit B's share by right of representation; B's spouse, however, receives no share of A's estate.
4.2 Second-Degree (Parentela) Heirs
If there are no heirs at the first degree, the estate passes to the deceased's parents. The mother and father inherit equal shares. If a parent predeceased the deceased, that parent's share passes by right of representation to their own descendants — that is, to the deceased's siblings. If one side (maternal or paternal) has no heirs at all, that entire share passes to the other side.
4.3 Third-Degree (Parentela) Heirs
If there are no heirs at either the first or second degree, the estate passes to the deceased's grandparents. If a grandparent predeceased the deceased, their share passes by right of representation to their descendants — that is, to the deceased's uncles, aunts on the paternal or maternal side.
An important exception applies here: if the deceased's spouse is surviving and all the heads of this parentela (the grandparents) have died, only their children (the deceased's uncles and aunts) may inherit. If none of them are alive either, the surviving spouse's presence blocks their descendants (i.e., the deceased's cousins) from inheriting, and the spouse inherits alone.
5. The Concept of the "Head of the Parentela"
The head of a parentela is the person who ranks first in line to inherit within that degree. As long as the head of the parentela is alive, their own descendants cannot inherit.
- Head of the first-degree parentela: the deceased's children
- Head of the second-degree parentela: the deceased's parents
- Head of the third-degree parentela: the deceased's grandparents
6. Inheritance Rights of Children Born Out of Wedlock
For a child born out of wedlock to inherit from the father, a legal parent-child relationship (paternity) must first be established — through the father's voluntary acknowledgment or a court ruling (e.g., based on a DNA test). Once paternity is established, the child born out of wedlock has the same inheritance rights as a child born within marriage (TMK Art. 498); otherwise, they receive no share of the estate.
7. Inheritance Rights of Adopted Children and Their Descendants
The one exception to the blood-kinship basis of the parentela system is adoption. An adopted child and their descendants inherit from the adoptive parent just as a biological child would (TMK Art. 500). Key features of this arrangement include:
- An adopted child is heir to both the adoptive parent and their own biological family, and may receive a share from both sides.
- The adopted child and their descendants are heirs only to the adoptive parent — not to the adoptive parent's other relatives.
- The inheritance relationship is one-directional: the adopted child inherits from the adoptive parent, but the adoptive parent (and their relatives) do not inherit from the adopted child.
8. The Surviving Spouse's Inheritance Right
The spouse is not automatically a member of any parentela; rather, the spouse inherits alongside whichever degree is entitled to inherit. If there are no heirs at the first or second degree, and at the third degree neither the heads of the parentela nor their children are alive, the spouse inherits the entire estate alone, thereby also excluding the state from inheriting.
8.1 Spouse Inheriting Together with First-Degree Heirs
When the spouse inherits together with first-degree (descendant) heirs, the spouse receives 1/4 of the estate (TMK Art. 499); the remaining 3/4 is divided equally among the children.
Example 1: If the deceased has two children and a surviving spouse: the spouse receives 1/4; the remaining 3/4 is split equally between the children, so each child receives 3/8.
Example 2: The children X and Y of the deceased's predeceased son A, the surviving son B, and the spouse E are all alive. E's share is still 1/4. Of the remaining 3/4, half (3/8) goes to B, and the other half is divided equally by right of representation among A's children (X = 3/16, Y = 3/16). Result: E = 1/4, B = 3/8, X = 3/16, Y = 3/16.
Example 3 (including an adopted child): Grandchildren X and Y, son C, adopted child D, and spouse E are alive. E receives 1/4. The remaining 3/4 is split equally among the sons; the predeceased son's share passes by representation to his children, and the adopted child receives a share equal to a biological child's. Result: E = 1/4, C = 3/12, D = 3/12, X = 3/24, Y = 3/24.
8.2 Spouse Inheriting Together with Second-Degree Heirs
When the spouse inherits together with second-degree heirs (parents, or their successors by representation), the spouse receives 1/2 of the estate (TMK Art. 499).
Example: If mother A, father B, and spouse E are all alive: E = 1/2, A = 1/4, B = 1/4. If both parents have died and only one sibling, B, survives, B inherits both parental shares (2 × 1/4) by representation: E = 1/2, B = 1/2.
8.3 Spouse Inheriting Together with Third-Degree Heirs
When the spouse inherits together with the heads of the third-degree parentela (grandparents) and their children, the spouse receives 3/4 of the estate (TMK Art. 499); the remaining 1/4 is divided equally between the maternal and paternal sides.
Example: Maternal grandmother A and grandfather B, paternal grandfather C and grandmother D, and spouse E are all alive: E = 3/4, and A = B = C = D = 1/16 each. If one grandparent on a side (e.g., B and C) has died, that share passes to the other grandparent on the same side (A = 1/8, D = 1/8). If all the heads of one side's parentela (e.g., A and B) have died, that side's entire share passes to the other side (C = 1/8, D = 1/8). This transfer can only occur if the spouse is alive.
8.4 Cases Where the Spouse Inherits Alone
If there are no heirs at the first or second degree, and at the third degree neither the heads of the parentela nor their children (uncles, aunts) are alive, the spouse inherits alone as the sole legal heir. In this case, the spouse's presence blocks both the more distant relatives' descendants at the third degree and the state from inheriting.
8.5 Special Circumstances Affecting Spousal Inheritance
- Once a divorce judgment becomes final, former spouses can no longer inherit from one another (TMK Art. 181); any death-related dispositions made in each other's favor automatically become void (unless otherwise agreed).
- If the plaintiff spouse dies while divorce proceedings are ongoing, and an heir continues the proceedings and proves the defendant spouse's fault, the surviving spouse can no longer inherit; otherwise, the marriage is deemed to have ended by death and the spouse's inheritance rights continue (TMK Art. 181/II).
- In an annulment (nullity of marriage) case, if the surviving spouse is found not to have acted in good faith at the time of marriage, that spouse cannot be a legal heir and loses any rights arising from dispositions made in their favor (TMK Art. 159).
9. Inheritance Contract vs. Will: Key Differences
An inheritance contract is a binding legal document drawn up before a notary, during the deceased's lifetime, jointly with the heirs, and containing mutual undertakings. It is formed by the shared will of the parties and, unlike a unilateral will, requires reciprocal commitment. It can only be terminated by mutual agreement of the parties, and may include provisions such as disinheritance, special conditions, or waivers of specific rights.
A will, by contrast, is a unilateral act. It is drawn up solely at the discretion of the person making it and can be changed at any time while that person is alive. A will typically focuses on how property is to be distributed and is more flexible than an inheritance contract.
10. Reserved Share and the Action for Abatement
Inheritance law guarantees a reserved share that the deceased cannot fully eliminate even through a will. Heirs entitled to a reserved share include children, adopted children, grandchildren, parents, and the spouse. If a disposition by the deceased infringes on a reserved share, the affected heirs may bring an action for abatement (tenkis davası) to have that disposition annulled. The Supreme Court applies close scrutiny to dispositions that violate reserved shares.
11. How Is Estate Division Carried Out? Step-by-Step Process
- Legal heirs — and any appointed heirs — are identified.
- The deceased's full estate (assets and liabilities) is determined.
- The heirs attempt to reach agreement on division; if no agreement is reached, the matter is brought before the civil court of peace (sulh hukuk mahkemesi).
- If agreement is reached, a written estate division agreement is drawn up.
- Title deeds to real property and bank accounts are transferred according to the determined shares.
- Once tax and duty obligations are settled, the heirs receive their respective shares.
12. Certificate of Inheritance, Determination of the Estate, and Title Deed Procedures
The certificate of inheritance (veraset ilamı) is a binding document issued by the civil court of peace that officially establishes who the heirs are and their respective shares. It represents the first and most fundamental step in the estate division process.
During the determination of the estate, title deed records, bank statements, notarial documents, and tax office records are reviewed to establish the deceased's full assets and liabilities.
To register real property in the heirs' names, the certificate of inheritance, the death certificate, a copy of the civil registry record, and the heirs' identification documents are required. Closing bank accounts requires presentation of the certificate of inheritance; transferring vehicle ownership requires notarial approval. The transfer of company shares is likewise subject to the relevant institutions' own procedures.
13. Supreme Court View on the Certificate of Inheritance
In a decision of the 14th Civil Chamber of the Supreme Court (Yargıtay), the Court held that inheritance arising directly from the law is "legal heirship" (TMK Art. 495–501). The deceased may, through a will or inheritance contract, appoint a person to inherit all or a fractional share of the estate — a process called "appointment of an heir," and the resulting heir is called an "appointed heir." By contrast, leaving a specific item of property without formally appointing the recipient as an heir is called a "specific bequest," and the beneficiary is a "legatee."
According to the decision, determining whether a disposition constitutes an appointment of an heir or a specific bequest requires looking at the deceased's true intent; no particular set of words is required. Under Article 598 of the Civil Code, separate certificates may be issued for legal heirs and for appointed heirs or legatees; this is a matter of non-contentious jurisdiction, and the competent court is the civil court of peace.
The decision further emphasized that matters such as disinheritance, renunciation of inheritance, appointment of heirs, and unworthiness to inherit cannot be reflected in a certificate of inheritance issued through non-contentious proceedings; such disputes must instead be resolved through a case filed in the civil court of general jurisdiction (asliye hukuk mahkemesi). In the specific case reviewed, since the deceased's will left the entire estate to the spouse — who was already a legal heir — and no timely objection had been raised, the Court held that the plaintiff should have been issued a certificate confirming appointed-heir status rather than a plain legal-heirship certificate.
14. Disputes in Estate Division and Ways to Resolve Them
Disagreements among family members often arise over matters such as the valuation of the estate, the division of personal belongings, and interpretation of the deceased's wishes. Available paths to resolution include:
- Reaching an amicable settlement among the heirs (the ideal outcome)
- Mediation by family elders or professional mediation services
- If no agreement is reached, applying to the civil court of peace, where the court will formally determine the estate, set the shares, and, if necessary, order assets sold and the proceeds divided
Seeking guidance from a lawyer specializing in inheritance law can both save time and help preserve family relationships throughout this process.
15. Points to Consider During Estate Division
- Clarifying exactly who is entitled to what share
- Compiling a complete list of the deceased's assets, including any hidden debts or receivables
- Maintaining transparent communication among the heirs
- Completing title deed transfers, banking transactions, and tax payments on time
- Having the division agreement formally notarized
- Working with a lawyer experienced in inheritance law to ensure the process runs smoothly
16. Frequently Asked Questions
How long does an estate division lawsuit take? This varies depending on the complexity of the case and the court's workload, but such cases are generally resolved within two years. Disputes among the parties or related lawsuits can extend this timeline.
How is the estate divided when a father dies? The surviving spouse (the mother) receives 1/4 of the estate; the remaining 3/4 is divided equally among the children.
Can an estate be divided while the parents are still alive? No — in the legal sense, estate division cannot take place while a person is still alive. However, that person may voluntarily transfer property during their lifetime, with their own consent and involvement.
What happens if the estate is never formally divided? Any heir may apply to the civil court of peace. The court will review the estate and all assets and carry out the division; differences in the value of real property allocated to different heirs are typically balanced through cash payments.
How is the estate divided if there is a will? The estate is divided according to the deceased's wishes as expressed in the will, but the rights of heirs entitled to a reserved share are always protected. If the will infringes on those rights, the affected heirs may bring an action for abatement.
How is real property divided among heirs? The heirs first obtain a certificate of inheritance to establish their status as heirs. They then reach an agreement and draw up a division agreement, after which they apply to the relevant land registry office to have the necessary changes made to the title deed.
