DSI Land Consolidation: What You Need to Know Before You Lose Your Rights

Land consolidation is an administrative process that aims to create more productive parcels by merging scattered agricultural land. Carried out by the State Hydraulic Works (DSI), these operations are applied together with irrigation projects across millions of decares nationwide. However, because of the intensity of the application and the short time that public posting announcements remain on the village headman's board, many landowners remain unaware for years that their title has changed.

In this article we explain how the land consolidation process works, in which situations a loss of rights occurs, and which legal remedies affected landowners may pursue.

What Is Land Consolidation?

Land consolidation is the process of replanning agricultural land that has become small and fragmented through inheritance or sale transactions, reorganising it together with irrigation canals and roads into more functional parcels.

Two separate laws govern consolidation in Turkey. Law No. 3083, the Agricultural Reform Law on Land Arrangement in Irrigation Areas, covers consolidations carried out by DSI in irrigation areas and in areas designated by the President. Law No. 5403, the Soil Conservation and Land Use Law, regulates the protection and consolidation of agricultural land within a broader framework and provides the legal basis for applications carried out under the Ministry of Agriculture and Forestry. An annulment action may be filed before the administrative judiciary against consolidation acts under either law.

With the 2017 amendment to Law No. 6200, the authority for land consolidation was transferred to DSI. Where institutions and organisations other than DSI wish to carry out consolidation, they must apply to DSI, and in that case legal responsibility again rests with DSI.

The process works briefly as follows: in the area where it has decided on consolidation, DSI grades all parcels and prepares a new parcelling plan. This plan is placed on public display for thirty days at the village headman's office and on the DSI website. Owners who do not object during the posting period are deemed to have accepted the new parcelling plan, and the title registration becomes final.

In Which Situations Does a Loss of Rights Occur?

When consolidation operations are carried out in accordance with the law, they should not produce an adverse result for the owner. In practice, however, serious errors are frequently encountered.

Loss of area and parcel index

Compared with the situation beforehand, the average parcel index after consolidation can show serious drops. This drop in the index means that, although the owner receives land of the same surface area, the parcels are of lower quality; this is a clear violation of the principle of equivalence. For example, a parcel index that was 0.657 before consolidation falling to 0.541 afterwards reflects an actual loss of value.

Fragmentation and relocation to distant sites

The fundamental purpose of consolidation is to eliminate fragmentation. In practice, however, owners find that land which was previously a single piece has been divided into several parcels and scattered to locations kilometres apart. The Council of State has repeatedly ruled that such applications are incompatible with the purpose of consolidation.

Failure to protect fixed facilities

Fixed structures and facilities such as wells, irrigation installations, barns or vineyards must, as far as possible, be allocated to their former owner. Acting contrary to this rule breaches both the law and the settled case law of the Council of State.

Failure to hold the owner interview

Under the Regulation on the Application of Land Consolidation and On-Farm Development Services, an owner interview must be held with each owner on a holding basis before the new parcelling plan is prepared. In practice this stage is mostly skipped; parcelling operations completed without the interview are deemed unlawful in terms of form.

Unjustified deductions

Making deductions from owners' shares without any allocation of roads, canals or common facilities appearing in the parcelling plan constitutes a separate unlawfulness that vitiates the cause element of the act.

What Does the Council of State Say?

The 4th Chamber of the Council of State has developed consistent and strong case law in land consolidation cases. This case law adopts the following principles:

In its 2025 decisions, the Council of State further clarified these principles, annulling consolidation acts in cases where a fixed facility was not preserved for its former owner, where the parcel index dropped, and where the technical justification for the new allocation could not be shown (Council of State, 4th Chamber, Merits No. 2025/2076, Decision No. 2025/4058; Merits No. 2024/2359, Decision No. 2025/3873; Merits No. 2025/520, Decision No. 2025/3485).

"My Title Changed Years Ago - Can I Still File a Case?"

This is the most frequently asked and most critical question. Defendant administrations mostly make the following defence: "The posting announcement was made, no objection was raised, registration became final, the filing period has passed."

However, this defence is not always valid. The Council of State Administrative Case Chambers Board accepts that land consolidation acts are directly related to the right of property and are subjective in nature; for this reason, notification by public announcement made by posting on the headman's board cannot replace personal service. According to this case law, taking the public posting as the starting point of the filing period may infringe the essence of the right of access to the court.

In line with this approach, many owners who missed the public posting or learned years later that their title had changed are still able to use the avenue of litigation. However, because each case has its own particular circumstances, this matter should be assessed through a lawyer.

Annulment Action or Full Remedy Action?

Knowing the distinction between these two concepts is critically important for planning your legal route correctly.

The annulment action secures the setting aside of an unlawful consolidation act. If the court grants annulment, the registration becomes void with retroactive effect. However, the annulment decision alone does not cover the pecuniary loss suffered.

The full remedy action, on the other hand, secures compensation for the pecuniary loss suffered because of the unlawful act. Concrete losses such as crop losses incurred during the consolidation process, the diminution in the land's value, or the demolition of a fixed facility may be claimed through this action. The full remedy action may be filed together with the annulment action or separately after the annulment decision becomes final.

Accordingly, in order to fully remedy a loss of rights arising from a consolidation act, both types of action mostly need to be considered together.

Objection and Litigation Process

Objection to the administration: The parcelling plan may be objected to during the public posting period. The objection must be made in writing to the relevant DSI Regional or Branch Directorate. Oral or undocumented objections are not accepted. The objection must arrive by the close of business on the first working day following the end of the posting period.

Annulment action before the administrative court: If the objection to the administration is rejected, or if no reply is given within thirty days, an implied rejection arises. An annulment action may be filed before the administrative court within sixty days from that date. The principal evidence to be requested in the case is as follows:

• Land grading map and parcel index calculations
• Cadastral records of the old and new parcels
• Interview minutes or records showing that no interview was held
• Farmer registration system documents
• On-site judicial examination and court-appointed expert review

Frequently Asked Questions

Conclusion

Land consolidation is, when carried out correctly, an application that benefits the farmer. However, when the principle of equivalence, the mandatory owner interview and the requirement of technical certainty in the parcelling plan are not observed, it can produce results that severely harm the right of property. The case law of the Council of State provides strong protection in this area, and faulty applications are annulled by the courts.
