Who Can Acquire Land Through Adverse Possession? Conditions, Costs, and Step-by-Step Procedure

In Poland, the concept of adverse possession, known as 'zasiedzenie,' offers a legal pathway for individuals to acquire ownership of land they do not officially own but have occupied and managed as if they were the proprietor for a set duration. This legal mechanism is significant for both those using someone else's land without formal title and for landowners seeking to protect their property rights.

The core requirement for adverse possession is 'independent possession,' which goes beyond mere use. It involves acting like an owner, which can include fencing the property, cultivating the land, paying property taxes, or constructing buildings. Tenants or lessees, who are considered 'dependent possessors,' cannot claim ownership through this process. The required period for acquisition depends on the occupant's 'good faith' or 'bad faith.' A 20-year period applies if the occupant genuinely believed they were the legal owner at the time of taking possession, perhaps due to an error in a deed. A 30-year period is required if the occupant knew or should have known the land was not theirs but used it anyway, for instance, by developing an unused plot.

To successfully claim ownership through adverse possession, an individual must present compelling evidence to the regional court. This evidence can include proof of property tax payments, testimony from neighbors, historical and contemporary photographs, maps, documentation of fencing or utility connections, and records of land improvements. The legal procedure involves filing an application with the appropriate regional court, specifying the current owner or their heirs. The process incurs a court fee of 2,000 PLN, and if the claim is successful, the new owner must also pay a property tax of 7% of the property's value. Landowners can protect their property by regularly inspecting it and by interrupting the possession period, for example, by filing a lawsuit for recovery of the property or by entering into a lease agreement with the occupant, which changes their possession status from independent to dependent.
