Adverse Possession in Chile

Acquiring or defending land through long possession

The Chilean Civil Code calls it prescripción adquisitiva, or usucapión. A person who possesses property as if they were its owner, openly and without interruption, can eventually become the owner by court declaration. It is relevant to expats who have been living on land without clean papers, to families who inherited a plot that was never registered in their name, and to owners who discover someone else has been treating their land as their own.

Chile registers real estate at the Conservador de Bienes Raíces (CBR), and that registry shapes everything. Possession of registered land is protected by the inscription itself, so a person who simply moves in does not displace the registered owner. The law sets two paths, and understanding which one you are on is the first thing we do.

Ordinary and extraordinary prescription

The ordinary path requires what the law calls regular possession: a just title, good faith and a proper transfer. For real estate, the Civil Code sets a period of five years. The extraordinary path requires no title at all but a longer period of ten years. In both cases, possession has to be continuous, peaceful and exercised as an owner, not as a tenant or a caretaker.

Prescription is not automatic. The person who relies on it must raise it in court, and a judge cannot declare it on their own initiative. A court judgment is then registered at the CBR, which is what puts the new ownership on the public record.

What we handle

The registered-title obstacle

The Civil Code says that against a registered title, real estate can generally only be prescribed on the basis of another registered title, and the clock runs from that second inscription. The Supreme Court has repeatedly applied this strictly, so claims based only on physical occupation against a living registration often fail. There are exceptions in cases of overlapping registrations, and the facts matter a great deal.

Evidence of possession carries weight in every case: fencing, building, long-term use, utility accounts, property tax payments and witness testimony. Paying property tax alone does not make anyone an owner, and neither does a long family tradition without the other elements.

A separate route for small properties

Decree Law 2.695 provides an administrative regularization procedure, run through the Ministry of National Assets (Bienes Nacionales), for small properties held for a sustained period. It is not available in every situation, and it is not intended to legitimize a recent illegal occupation. We screen whether it fits before recommending it.

Common mistakes owners and occupants make

Occupants often assume that a long stay or a friendly handshake with the old owner is enough. It is not: possession must be as an owner, and a tolerated stay, a lease or a caretaker arrangement points the other way. Owners, for their part, sometimes ignore an occupant for years because the land is far from where they live, which lets the evidence build against them.

If you are buying land that someone else uses, the same rules matter. We recommend a registry review and a site visit before the purchase, because a buyer inherits the occupant problem along with the title.
