When the Turkish Land Register Is Wrong: Tapu Errors and Cadastral Corrections
Turkey's land register is centrally kept, publicly reliable and, occasionally, wrong. The law anticipates that. It protects the buyer who relied on it in good faith, makes the State liable for the damage its records cause, and puts hard deadlines on putting things right. Here is how those three mechanisms fit together.
The register says who owns it. The cadastre says where it is. They can disagree.
Foreign buyers arrive in Turkey and are told, correctly, that the title system is strong. Ownership is recorded centrally by the General Directorate of Land Registry and Cadastre, the record is authoritative, and the transfer of a property is an act of registration rather than a private exchange of documents. Compared with jurisdictions where ownership rests on a chain of private deeds, this is a considerable advantage, and it is one of the genuine reasons Turkish property is straightforward to buy.
What that reassurance tends to flatten is that there are two records, doing two different jobs. The land register, the tapu sicili, records legal facts: who owns the parcel, in what shares, and what rights, mortgages, liens and annotations are registered against it. The cadastre records physical facts: the parcel's measured area, its boundaries and its position on the map. A property has an entry in both, and it is entirely possible for one to be impeccable while the other is wrong.
That is not a theoretical concern. Cadastral surveying in Turkey has been carried out over a long period, with varying technology and varying precision, and renewal work has in places produced registered parcel areas that differ from what was recorded before. Those changes have generated compensation claims against the State under the land-register liability provision, a pattern examined in the journal Geomatics, Natural Hazards and Risk in 2025, which noted that some discrepancies fall within tolerable survey error while others are significant enough to warrant compensation. If you own rural land, a large plot or a villa with a garden, this is the category of problem most likely to touch you.
The law's response has three parts, and they are worth separating because buyers tend to collapse them into a general sense that the system is safe. The first is protective: a person who acquires in good faith, relying on what the register says, is protected in that acquisition. The second is compensatory: where the keeping of the register causes damage, the State answers for it. The third is procedural and unforgiving: corrections and challenges run on deadlines, and those deadlines do not pause because the owner lives in another country.
It is the third that catches foreign owners. The protective and compensatory provisions are generous by international standards. The procedural ones assume an owner who is present, who receives notices at an address that is actually monitored, and who acts within weeks. An owner who visits twice a year and whose Turkish correspondence goes to an empty apartment is exposed not because the law is harsh but because the clock is indifferent.
This guide sets out what each of the two records actually contains, how errors in each are corrected, what deadlines apply, and what an owner abroad should have in place so that a notice does not expire unread. It states the provisions and the periods; it does not attempt to value a claim or predict how a court would decide one, because neither can responsibly be generalised.
Land Register and Cadastre
The provisions that govern getting it wrong, and putting it right
How to establish, and then fix, an error affecting your property
The order matters. Each step narrows what the problem can be, and several of the later options close permanently if the early ones are skipped.
Pull both records, not one
Obtain the current land register entry for the parcel and the cadastral data for it. The register entry gives the owner, the shares, and the full annotations and declarations pages. The cadastral data gives the parcel's recorded area, boundaries and map position. Turkish citizens and residents can reach much of this through the state e-government service; a foreign owner will usually work through a lawyer or directly with the land registry office holding the file.
Compare the record against the ground
Walk the boundary against the cadastral map, and compare the recorded area against what is actually enclosed. Fences, walls, access tracks and outbuildings that have been in place for years are the usual sources of divergence, and a neighbour's structure sitting inside your parcel is a materially different problem from your own wall sitting inside theirs. Where the parcel is large, rural or irregular, this is work for a licensed surveyor rather than for a tape measure and optimism.
Classify the error
Decide which record is wrong. An incorrect name, identity number or ownership share, or an annotation that should have been lifted and has not been, is a register defect. An incorrect area, boundary or map position is a cadastral defect. Where both look wrong, they are usually the same underlying event recorded twice, and the cadastral question is generally the one to resolve first because the register describes a parcel the cadastre defines.
Use the administrative route where it exists
Cadastral errors of measurement, area and boundary are corrected administratively under Article 41 of the Cadastre Law No. 3402, rather than requiring litigation as a first step. The correction is made and then notified to the owners and other right holders. This is the quickest route available and it is worth exhausting before anything more adversarial, both because it is faster and because a contested court process starts from a worse position if the administrative option was never tried.
Watch the 30-day window in both directions
Once a correction under Article 41 is notified, an affected party has 30 days to bring an action in the civil court to have it cancelled, after which it becomes final. That cuts both ways. If a correction has been made that damages your position, 30 days is all you have to attack it. If a correction has been made in your favour, the same 30 days must run before you can treat the matter as settled. Diary the date from the notification, not from when you read it.
Consider the compensation claim separately
Fixing the register and being compensated for what the error cost you are two different proceedings. Where damage has arisen from the keeping of the land register, Article 1007 of the Civil Code makes the State liable, on a strict basis, and the State may then pursue officials at fault. Whether a claim is available on your facts, and within what period it must be brought, is genuinely contested in Turkish commentary and is not something to determine from a guide. Take it to a Turkish lawyer with the file in front of them.
Six errors that actually turn up on Turkish property files
None of these is exotic. All of them are cheaper to find before completion than to litigate afterwards.
Identity and name errors
A misspelled name, a transliterated name recorded inconsistently, or a wrong identity or passport number. Trivial-looking, and capable of stalling a sale, an inheritance transfer or a mortgage application years later when the entry no longer matches the document you are holding.
Area discrepancies
The registered area of the parcel does not match what the cadastral measurement now shows, often following renewal survey work. Some differences sit within tolerable survey error; others are large enough to change what the property is worth and to found a compensation claim.
Boundaries that moved
The line on the cadastral map and the line on the ground have diverged, usually through decades of fences and walls being rebuilt approximately. The question is always which one the register supports, and the answer is not always the one that has been respected in practice.
Encroaching structures
A neighbour's wall, outbuilding or extension sits partly inside your parcel, or yours inside theirs. Long-standing occupation does not automatically resolve who owns the strip, and the remedy available depends heavily on how the encroachment arose and how long it has stood.
Stale annotations
A mortgage that was discharged but never lifted, a resale restriction whose period has expired, a lien relating to a settled dispute. The underlying restriction may have lapsed while the entry survives, and the entry is what a future buyer, lender or notary will read.
Share and inheritance errors
Co-ownership shares recorded incorrectly, or an inheritance transfer only partly carried through the register. These compound quietly across generations and tend to surface at the worst possible moment, which is when somebody finally tries to sell.
Register defect, cadastral defect, or ownership dispute
Three different problems that present almost identically to an owner, and are handled in three different places.
| Register defect | Cadastral defect | Ownership dispute | |
|---|---|---|---|
| Typical symptom | Wrong name, share or a stale annotation | Wrong area, boundary or map position | Someone else asserts a right to the parcel |
| Which record is wrong | The land register | The cadastral survey | Possibly neither — the claim is substantive |
| Governing provision | Civil Code No. 4721 | Cadastre Law No. 3402, Art. 41 | General property and civil procedure law |
| Administrative fix available | Often, for clear clerical errors | Yes, under Article 41 | Нет |
| Hard statutory deadline | Depends on the defect | 30 days from notification | Art. 12/3 preclusion may apply |
| Good-faith protection relevant | Yes — Article 1023 | Sometimes, depending on the facts | Yes — often decisive |
| State liability may arise | Yes — Article 1007 | Yes — Article 1007 | Only if a registry error caused it |
| Where it ends up if contested | Civil court | Civil court, within the 30 days | Civil court |
