Adverse Possession

When and How Property Ownership Is Acquired Without a Title Deed

Adverse possession (usucapion) constitutes a foundational method of acquiring ownership under Greek in rem law. It applies to cases where ownership of a real estate asset is established without a notarized title deed, through long-term and uninterrupted possession – namely, actual use and occupancy.

Adverse possession continues to hold immense practical significance, particularly for agricultural lands, old family estates, and inherited properties where title deeds are incomplete, defective, or entirely non-existent.

As a method of acquiring ownership, adverse possession does not rely on a transfer from a previous owner. Instead, it is based on the long-term exercise of actual physical control over the property with the intent to possess it as the sole owner (animus domini).

The law recognizes that stable, public, and continuous possession over a long period eventually establishes a legal right of ownership, regardless of the existence of a formal contract.

Greek law distinguishes between two forms of adverse possession:

Ordinary adverse possession requires continuous physical possession of the property for a period of ten years, the existence of a title deed (such as an invalid contract or a verbal inheritance transfer) that suffers from a legal defect, and the good faith of the possessor at the time of acquisition. In practice, the application of ordinary adverse possession is limited, as all of these legal requirements rarely coexist.

Extraordinary adverse possession is the most common form. It requires continuous possession of the property for a period of twenty years, without requiring good faith or any pre-existing title deed. The critical element in extraordinary adverse possession is exercising possession with the intent of ownership – meaning the possessor behaves as the exclusive owner of the property, without recognizing any third-party claims or rights.

The legal concept of possessing as an owner is not identical to mere physical use. It requires executing visible actions that demonstrate authority over the property, such as cultivation, fencing, construction, maintenance, overall development, and general behavior that outwardly presents the possessor as the owner to the public. This possession must be continuous and uninterrupted.

Proving adverse possession is the most critical and legally demanding stage. Ownership does not establish itself automatically by operation of law; it must be proven through a combination of admissible evidence, such as witness testimonies, tax records, official asset declarations, historical maps, aerial photographs, and expert technical reports. The completeness of this evidence heavily dictates the success of the case.

Adverse possession is of paramount importance concerning the National Cadastre. In many instances, properties held by families for decades appear in cadastral records as “of unknown owner” or contain highly inaccurate registrations.

Adverse possession can serve as the legal basis for rectifying these cadastral entries, though certain cases will strictly require judicial recognition of the right.

Adverse possession also frequently arises in inherited real estate, especially when an estate remains undivided for a long period or when a formal acceptance of inheritance has never been executed. In these scenarios, the long-term, exclusive possession by a single heir can, under specific legal conditions, lead to the acquisition of full ownership via adverse possession – provided the statutory criteria are met and the intent to exclude the remaining co-heirs is clearly proven.

Adverse possession is only definitively recognized through a binding court ruling. For this reason, filing a declaratory lawsuit for the recognition of ownership is required, which must be backed by a thorough, cohesive legal and evidentiary foundation. This judicial recognition is a prerequisite for any future property transfer, notarial act, or rectification within the Cadastre.

Adverse possession cases demand a highly specialized legal approach.

A superficial approach or deficient documentation can lead to the dismissal of the lawsuit and the irreversible loss of valuable property rights. Formulating the correct legal strategy, in close cooperation with technical consultants where necessary, is decisive.

In conclusion, adverse possession is not a legal loophole, but rather the formal recognition of a long-standing factual reality. Guided by precise legal counsel and backed by thorough documentation, it serves as a powerful legal tool for securing your real estate assets and restoring legal order to your property portfolio.
