Why you should check your fence

The Polish Supreme Court recently warned owners about the risk of losing land if they ignore boundary encroachments. Moreover, the court stressed that actual use of land matters more than paper records. Therefore, a fence placed for years can become the de facto property line. However, formal documents like land register entries still matter. In addition, the court said judges must consider long-term, uninterrupted possession when hearing cases.

How adverse possession (zasiedzenie) works

Poland allows a legal claim called zasiedzenie. In short, someone who treats land as theirs for a long time may claim ownership. Moreover, the law requires uninterrupted and apparent possession. In addition, the possessor must act like an owner. For instance, they can fence, farm, maintain, or pay costs. If they believe in good faith they own the land, the required period is 20 years. However, if they know they lack ownership, the period extends to 30 years. Consequently, evidence matters. Witness statements, photos, bills, and maintenance records can prove possession. Therefore, courts focus on facts on the ground rather than only maps or księgi wieczyste (land registers).

Why this matters for expats

Many foreign residents buy property and trust paperwork. However, time and local practice can erode protection. For example, a neighbour may move a fence by a few metres. Moreover, you might not notice if you live abroad or travel often. In addition, Polish administrative terms may confuse newcomers. ZUS refers to social insurance. NFZ denotes the national health fund. PESEL is the national identity number. A mandat means a fine. Therefore, you should not assume that a registered right always protects you.

Practical steps to protect your property

First, inspect boundaries regularly. Secondly, compare the physical fence with official maps. In addition, hire a licensed surveyor to mark borders. Moreover, file for rozgraniczenie (boundary determination) at the local court when needed. Therefore, request the neighbour to restore the correct line. If the neighbour persists, start legal action quickly. In practice, courts accept interruption of adverse possession if the owner acts. Consequently, a formal demand, a registered letter, or an immediate court filing can halt the clock.

💡 GOOD TO KNOW: As an expat, register and monitor your property. Keep clear proof of your ownership. For example, save deeds, bills, photos, and survey reports. In addition, use a local lawyer who understands land law and the courts. If you rent the plot, inform your tenant about boundaries. Finally, react quickly to any encroachment to stop the adverse possession clock.

Remember, the law does not require compensation when adverse possession succeeds. Therefore, owners who delay may lose land without payment. However, prompt action and good records usually protect rights. In addition, consult a property lawyer if you spot a problem. The consequences of inaction can become irreversible.
