Expropriation of Property in Türkiye: Compensation and Legal Remedies for Owners

An owner whose property is expropriated by a Turkish public authority is entitled to compensation determined through a specific legal process, and may challenge both the amount of compensation and, in limited circumstances, the underlying expropriation decision itself. Where an authority takes de facto possession without a formal expropriation decision, separate remedies apply for that situation as well.

Expropriation (kamulaştırma) is the compulsory acquisition of privately owned real property by the state or another public authority for a public purpose, against compensation. It differs from a voluntary sale in that the owner does not choose to transfer the property; the law instead sets out a compensation process. A related but distinct situation is de facto expropriation (kamulaştırmasız el atma), where an administration occupies or restricts use of privately owned land without following the formal expropriation procedure, which gives rise to its own compensation claim.

The Expropriation Law sets out the procedure for formal expropriation, including notice to the owner, valuation by a commission, and the right to apply to court to contest the compensation amount. The Turkish Constitution guarantees the right to property and requires that expropriation be carried out only for public benefit and against payment of fair compensation. Separate case law and administrative practice address de facto expropriation, where an owner whose property has been occupied or restricted without formal expropriation can seek compensation through the courts.

Turkish courts routinely review expropriation valuations through court-appointed experts, who assess factors such as the property's location, zoning status, size, and comparable transactions. Courts also review whether the expropriating authority followed the required notice and procedural steps. In de facto expropriation cases, courts examine when the administration's occupation or restriction effectively deprived the owner of the use of the property, since this affects both the compensation claim and any applicable time considerations.

A recurring debate concerns how compensation should reflect the property's realistic market value at the relevant date, including its development potential, rather than only its current use. Another debate concerns the boundary between a lawful zoning restriction, which an owner must generally tolerate without compensation, and a restriction so severe that it amounts to de facto expropriation requiring compensation. These distinctions are highly fact-specific.

An owner who disagrees with the compensation offered in a formal expropriation must generally apply to court within the period specified for objecting to the valuation. An owner affected by a de facto taking, where no formal expropriation decision was issued despite the administration's occupation or restriction of the property, may bring a separate claim for compensation based on that occupation.

Formal expropriation valuation objections are subject to a defined and relatively short period after notification of the compensation decision, so an owner who disagrees with the offered amount should act quickly. Claims arising from de facto expropriation are also subject to limitation periods that depend on when the interference began and its nature, making early legal review important to avoid losing rights through delay.

Expropriation compensation disputes and objections to the expropriating authority's valuation are generally heard by the civil courts designated for expropriation matters at the location of the property. Claims relating to de facto expropriation, and to related administrative decisions, may fall within the jurisdiction of either the civil or the administrative courts depending on the specific claim and how the case is framed.

• the title deed and any zoning or cadastral records for the property;
• the expropriation decision and valuation notice, if issued;
• correspondence with the expropriating authority;
• evidence of the property's condition, use and development status;
• any documentation of comparable sales or valuations in the area;
• evidence of the date and nature of any de facto occupation or restriction, where relevant.

Owners sometimes assume that accepting an initial compensation offer is the only option, without realising that the amount can be challenged through the courts with expert valuation input. Foreign owners in particular sometimes overlook that a restriction on land use through zoning, without physical occupation, does not automatically amount to compensable expropriation, and the specific facts must be assessed. Delay in reacting to a valuation notice or to visible occupation of land by an authority is a common and costly mistake, given the applicable time limits.

Expropriation disputes are technical and time-sensitive, turning heavily on valuation evidence and on precisely when an administration's actions crossed into a compensable taking. We recommend that owners facing an expropriation notice, or discovering unauthorised occupation of their land by a public authority, seek a case-specific review of the documents and timeline as early as possible, so that the applicable objection periods are not missed.
