Adverse Possession of Real Estate in Greece

Adverse Possession of Real Estate in Greece: What It Is, When It Applies and How It Is Claimed

There are many properties in Greece that have been possessed, used or cultivated for decades by people who do not hold a complete or clear title deed.

Agricultural plots passed from one generation to the next without a formal contract. Houses used for many years without the ownership status having been properly settled. Land that has been declared, cultivated or fenced by the same family for a long period of time, without a clear notarial title.

Adverse possession is the legal mechanism through which, under specific conditions, long-term possession of real estate may lead to acquisition of ownership.

It is not mere occupation, nor arbitrary appropriation of someone else’s property. It is a legal institution under the Greek Civil Code, intended to serve legal certainty and to regularise ownership situations that have remained unclear for a long time.

What Is Adverse Possession?

Adverse possession is a way of acquiring ownership through possession for a specific period of time.

The central concept is possession. It is not enough for someone to be occasionally present on a property or to use it with another person’s tolerance. They must exercise acts over the property as an owner would, with the intention to possess it as their own.

Depending on the nature of the property, such acts may include:

Cultivating an agricultural plot.

Fencing or clearing the land.

Constructing or maintaining a building.

Leasing the property to a third party.

Paying taxes or charges connected with the property.

Declaring the property in tax or administrative records.

Continuous use as a residence, storage space, professional premises or agricultural holding.

Adverse possession is not recognised automatically because someone has been “dealing with” a property. It requires specific legal basis and sufficient proof.

Ordinary and Extraordinary Adverse Possession

The Greek Civil Code provides for two basic forms of adverse possession: ordinary and extraordinary.

Ordinary adverse possession

Ordinary adverse possession requires possession of real estate for ten years, good faith and a lawful title.

Good faith means that, at the time possession was acquired, the possessor believed, without gross negligence, that they had lawfully acquired ownership.

A lawful title is a legal act or document which, if it had not been defective, could have led to acquisition of ownership. In practice, this may include a contract that suffers from a defect or derives from a person who ultimately did not have full power to dispose of the property.

Ordinary adverse possession is more demanding evidentially, because ten-year possession is not enough. The title and good faith at the time possession was acquired must also be examined.

Extraordinary adverse possession

Extraordinary adverse possession requires possession for twenty years. No lawful title or good faith is required.

This is why extraordinary adverse possession often appears in cases involving properties without a clear notarial history, especially agricultural plots, old family properties or real estate used for decades without proper transfer documentation.

The absence of title does not mean that the case is simple. On the contrary, where there is no title, proof of possession throughout the twenty-year period becomes decisive.

The Requirements for Adverse Possession

To establish adverse possession, specific and continuous possession as owner must be proven.

Possession as owner

The possessor must behave as the owner of the property. Mere custody, occasional use or use with someone else’s permission is not enough.

For example, a person who cultivates, fences, declares and leases a property as their own is assessed differently from someone who merely uses it because the owner temporarily allowed them to do so.

Continuity of possession

Possession must be exercised for the required period. Minor or natural interruptions of use do not necessarily prevent adverse possession, especially in the case of properties not used on a daily basis, such as agricultural land.

However, abandonment, dispossession or substantial interruption of the relationship with the property may raise issues as to interruption or failure to complete the required time.

Open possession

Possession must be exercised openly. Adverse possession is not based on a hidden or unclear relationship with the property. Acts of possession must be capable of being perceived by third parties, neighbours, the local community or the competent authorities.

Duration

Ordinary adverse possession requires ten years, while extraordinary adverse possession requires twenty years.

The possessor’s time may, under certain conditions, be combined with the possession time of predecessors. For example, if a father possessed the property for fifteen years and the child then continued possession for another five, completion of the twenty-year period may be examined, provided there is lawful succession in possession and the facts can be proven.

What Adverse Possession Is Not

Adverse possession is often confused with other situations.

Adverse possession is not:

Mere tolerance by the owner.

Use of a property as a tenant.

Hospitality or permission granted by a relative.

Occasional passage through land.

Arbitrary use without stable and provable possession.

Holding without intention to possess as owner.

A tenant, for example, does not become owner of the leased property because they have used it for many years. Their use is based on a lease relationship, not on possession as owner.

Similarly, use of property within the context of family tolerance must be assessed with particular care, because it does not automatically lead to adverse possession.

State-Owned Property, Municipal Property and Special Cases

Particular caution is required where the property appears, or may be considered, to belong to the Greek State, a municipality, a public law entity or another body subject to a special protective regime.

Adverse possession against the State should not be treated in the same way as adverse possession between private individuals. As a rule, acquisition of ownership by adverse possession against the State is highly restricted and depends on specific provisions and strict requirements.

There are special cases, including rules concerning certain properties, areas or time requirements, which must be examined individually. Article 4 of Law 3127/2003, in particular, has been the subject of significant case law, but it does not apply generally and indiscriminately to every property claimed against the State.

For this reason, where the State is involved or there is an indication of public property, a specific legal review is required before any action is taken.

Adverse Possession and the Greek Cadastre

The operation of the Greek Cadastre has made adverse possession cases more demanding.

If a property is registered in the Cadastre under another person’s name, adverse possession does not by itself automatically change the registration. The appropriate correction or recognition procedure is required, depending on the stage of the cadastral registration and the specific facts of the case.

Particular attention is required for properties registered as “unknown owner”. In such cases, the expiry of correction deadlines may have serious consequences. The existence of possession or even the substantive requirements of adverse possession should not be treated lightly, because the cadastral stage and available procedures decisively affect the legal strategy.

The correct approach depends on whether the area is still under cadastral survey, whether initial registrations are involved, whether registrations have become final or whether the property bears a special registration status.

How Adverse Possession Is Proven

The success of an adverse possession case depends largely on evidence.

Useful evidence may include:

Old photographs of the property.

Aerial photographs.

Topographic diagrams.

E9 property tax declarations or other tax records.

Utility bills.

Proof of payment of charges or taxes.

Agricultural subsidies or cultivation declarations.

Lease agreements or grants of use to third parties.

Documents from municipalities, communities or public authorities.

Witness testimony from neighbours or persons familiar with the use of the property.

Evidence of fencing, cultivation, maintenance or construction.

No single item of evidence is always sufficient on its own. What matters is the creation of a coherent evidential picture covering the required period and proving actual possession as owner.

The Procedure for Recognition of Adverse Possession

Step 1 — Title and cadastral review

Before any court action, the ownership and cadastral status of the property must be reviewed.

It must be examined whether there is a title, whether it has been transcribed or registered, who appears as owner, whether there are encumbrances, whether the property is registered as unknown owner, whether the State is involved and whether any deadlines or procedural restrictions apply.

Step 2 — Collection of evidence

All documents and factual elements proving possession must be collected. In adverse possession cases, preparation is crucial. A claim without sufficient evidence may be dismissed, even if the claimant has in fact used the property for years.

Step 3 — Legal assessment of the type of adverse possession

The lawyer assesses whether ordinary or extraordinary adverse possession can be established, whether an action for recognition of ownership is required, whether correction of cadastral registration must be requested and who must be sued.

Choosing the correct defendant is critical, especially where there is a cadastral registration in favour of a third party, an unknown owner indication or involvement of the State.

Step 4 — Filing the lawsuit

Recognition of ownership by adverse possession is usually pursued through a lawsuit before the competent court.

The lawsuit must accurately describe the property, the manner in which possession was exercised, its duration, succession in possession where applicable, the evidence and the legal basis of the claim.

Step 5 — Registration of the judgment

After the court judgment is issued and provided the legal requirements are met, the judgment is registered with the competent Cadastral Office or transcribed at the competent Land Registry, depending on the area and the applicable publicity system.

Only then does the legal regularisation acquire practical completeness against third parties and in the public records.

Frequently Asked Questions About Adverse Possession in Greece

Can I acquire property by adverse possession if I have no contract at all?

Yes, under certain conditions. Extraordinary adverse possession does not require a title, but it does require twenty-year possession. This must be proven with specific evidence, not merely by stating that “the property has always been ours”.

Is declaring the property in E9 enough?

No, not on its own. An E9 declaration may be useful evidence, but it is not sufficient by itself to prove adverse possession. It must be combined with acts of actual possession and other supporting evidence.

If the property is registered in the Cadastre as “unknown owner”, can I claim it?

There may be options for correction or judicial claim, but the answer depends on the area, the stage of cadastral registration, the applicable deadlines and the available evidence. “Unknown owner” cases require prompt and specialised handling.

Can State-owned property be acquired by adverse possession?

As a rule, adverse possession against the Greek State is highly restricted. Specific provisions and exceptions may be examined in particular cases, but there is no general rule that twenty-year possession is enough to acquire ownership against the State.

Does the owner’s objection interrupt adverse possession?

A simple oral or written objection does not always amount to interruption of possession. However, it may have evidential significance and affect the assessment of the case. Interruption or challenge of possession must be examined on the basis of the specific facts and actions taken.

Can I sell property that I possess by adverse possession before having a recognised title?

In practice, transferring property without a clear and recognised title is extremely difficult. Prior legal regularisation, judicial recognition or another appropriate procedure is usually required so that the right can be registered and accepted in a transaction.

Does adverse possession apply to agricultural land outside city plans?

Yes, it may apply, provided the legal requirements are met. In practice, many adverse possession cases concern agricultural plots, cultivated land or properties outside city plans. However, special review is required regarding boundaries, ownership history, the Cadastre, possible forest status and potential State claims.
