Unlawful Occupation of Land in Poland: Protecting Possession and Recovering Your Property

You come back to your plot after a while away and find your neighbour has shifted the fence a bit further onto your side than it should be — or worse, a stranger has moved into your empty house and claims that "nobody complained, so it's mine now." Polish law gives an owner two separate routes to deal with this: a fast possession-protection claim, and a slower but conclusive ownership (vindication) claim. This guide explains how they differ, when to use which, and which deadlines you cannot afford to miss.

This guide is general legal information, not legal advice. Which route is right for you depends on when the interference happened, what documents you hold, and how long the disputed situation has lasted. Where advice or representation is needed, the matter should be assessed by a qualified Polish lawyer. Twoja Sprawa helps you organise the documents for that assessment.

Key points

• You have two independent routes: a fast possession-protection claim (Article 344 of the Polish Civil Code, Kodeks cywilny — "KC") and a vindication claim for the return of the property (Article 222 § 1 KC).
• Possession protection does not examine title to the property — what matters is only the fact of possession and whether it was interfered with without permission.
• You have just one year from the interference to bring a possession claim — after that, only the vindication route remains open.
• The vindication claim takes longer, but it settles the question of ownership conclusively and, as a rule, does not become time-barred in the way ordinary property claims do.
• If force was used you can call the police — but it is the court, not the police, that ultimately decides a land dispute.
• This is a different matter from evicting a tenant — separate rules protecting tenants' rights apply there.

Two routes to protection: possession and vindication

When someone unlawfully occupies your property — a neighbour moves the fence and starts using a strip of your land, someone moves into an unoccupied house or plot, or a company starts storing materials on your land without consent — Polish law gives you two independent tools:

The two routes can be used independently of each other — sometimes you start with the faster possession claim, then run a vindication claim in parallel or afterwards if title to the land is disputed.

Possession protection — the fast route (Article 344 KC)

Article 344 of the Polish Civil Code gives a possessor (not necessarily the owner — actual factual control is enough) a claim against anyone who has unlawfully interfered with their possession, for restoration of the previous state and cessation of further interference. The key features of this protection:

• It does not matter whether the possession was lawful — what counts is simply that, before the interference, you were the one in factual control of the property, and that the interference happened without your consent and without legal basis (i.e. it was "self-help" by the other side).
• The court does not decide who the owner is — it examines only the last state of possession and whether it was interfered with. This has its own logic: the point is a quick restoration of order, before the "who is actually right" question is settled in longer proceedings.
• The claim expires if not pursued within one year of the interference. This is a short, strict deadline — once it passes, possession protection is no longer available, regardless of the circumstances.

A possession-interference case is heard by the district court (sąd rejonowy). If you win, the judgment orders the person who interfered to restore the previous state (e.g. remove the relocated fence, vacate the occupied land) — even if it later turns out that they actually held the stronger legal title to the disputed land (in that case, their route is a separate vindication claim, not unlawful self-help).

The vindication claim — a conclusive ruling on ownership (Article 222 § 1 KC)

Article 222 § 1 of the Polish Civil Code gives an owner a claim for the return of the property against anyone who is in factual control of it, unless that person has a right to hold it that is enforceable against the owner. Unlike possession protection:

• You have to prove title — with a land and mortgage register (księga wieczysta — the Polish public property register recording ownership and encumbrances) extract, a notarial deed (akt notarialny — a deed executed before a Polish civil-law notary, notariusz, whose role differs from a UK notary public), or an inheritance decision.
• The court rules on the merits of title — this is ordinary (contentious) litigation, which can run for longer, particularly if the defendant disputes your ownership.
• Alongside the claim for return of the land, you may also consider supplementary claims — for example compensation for use of the land without agreement, return of proceeds collected (e.g. crops), or damages for harm caused while the property was unlawfully held — the scope depends on whether the possessor was acting in good or bad faith.

A vindication claim relating to real property generally does not become time-barred in the way typical property claims do. That does not mean you can wait indefinitely, though — the longer the unlawful situation continues, the harder it becomes to prove your case, and the greater the risk that the person holding the land will try to rely on adverse possession (zasiedzenie — acquisition of ownership through sufficiently long possession) if they have held it long enough as if they were the owner. We cover the conditions and time limits for that in our guide Acquiring Property Through Adverse Possession in Poland.

Which route to choose — a practical comparison

• Recent interference (within the last year), where the dispute is mainly about who was there first — start with possession protection. It is faster and does not require proof of title.
• Interference more than a year ago — the possession route is closed, leaving only the vindication claim, which requires proof of ownership.
• Situations where title is unclear or disputed (e.g. the neighbour claims to be the owner of the disputed strip of land) — a vindication claim settles the matter conclusively, whereas possession protection only restores the state before the interference, without deciding who is actually right about ownership.
• Nothing stops you from using possession protection shortly after the interference while also preparing for a vindication case, if you expect the other side to challenge your title.

Documents and evidence worth gathering

Common mistakes

1. Waiting more than a year to react. The most common mistake — after a year you lose the faster possession route and are left only with the longer vindication proceedings.
2. Taking the law into your own hands. Removing someone else's belongings from the occupied land yourself can itself be treated as an interference with their possession — meaning you could end up being the one taken to court.
3. No documentation of the state before the interference. Without photos or other evidence, it is difficult to show what the "last peaceful state of possession" actually looked like.
4. Confusing a land-occupation case with a boundary dispute. These are different legal mechanisms — a boundary-marking procedure (rozgraniczenie) establishes where the boundary runs, whereas possession protection and vindication claims apply once an actual interference or occupation has already occurred. More on the former in our guide Boundary Disputes in Poland: The Rozgraniczenie Procedure Step by Step.
5. Relying solely on police intervention. The police can identify individuals and record an incident report, but it is the civil court that decides who has the right to the land.
6. Not reacting to early warning signs. The longer a stranger uses your property without objection from you, the stronger their position becomes — including in the context of a possible future adverse-possession claim.

Step-by-step: what to do

1. Document the interference immediately — photos, the date, and a description of the circumstances.
2. Check how long ago the interference happened — this determines whether the possession route is still open (deadline: one year).
3. Consider reporting it to the police, especially if the interference was sudden or involved force.
4. Send the person occupying the property a written demand to vacate (with proof of delivery) — this builds evidence and sometimes is enough on its own.
5. File a claim for protection of possession with the district court, if you are still within the one-year deadline.
6. Prepare documents proving ownership, if you are planning a vindication claim (in parallel with, or instead of, possession protection).
7. Consider supplementary claims — compensation for use without agreement, return of proceeds — if the situation has gone on for longer.
8. After judgment — if the other side does not leave voluntarily, apply for enforcement through a court bailiff (komornik).

The role of the police

The police intervene where there is a breach of public order or where force or a disturbance of the peace is involved — they can identify people at the scene, prepare an incident report, and sometimes caution the parties. However, this does not replace a court ruling — a dispute about who has the right to the land can only be resolved by a civil court. A police report can, however, be valuable evidence of the date and circumstances of the interference in later court proceedings.

Time limits and limitation periods

• Possession-protection claim (Article 344 KC) — one year from the moment of the interference. This is a strict (preclusive) deadline — once it passes, the claim lapses regardless of the circumstances.
• Vindication claim relating to real property (Article 222 § 1 KC) — as a rule not subject to a limitation period.
• Supplementary claims (compensation for use, return of proceeds, damages for deterioration of the property) — subject to the ordinary limitation rules for property claims, generally running to a few years.
• Adverse possession by the person interfering (zasiedzenie) — this risk grows with the length of uninterrupted, open possession "as an owner": as a rule 20 years in good faith, 30 years in bad faith. This is a further reason not to delay reacting to an occupation of your property.

How this differs from evicting a tenant

It is worth distinguishing the situation described here from evicting a tenant — where the person occupying the property moved in under a tenancy agreement (even an oral one) or another title that has since expired or been terminated. Different rules protecting tenants' rights apply there, sometimes including an obligation to provide alternative social housing, and a different court procedure. If your situation involves a former tenant rather than someone who never had any legal title to the property, see our guide Evicting a Tenant in Poland: How the Court Procedure Works (in Polish).

Frequently asked questions

Do I need to prove I'm the owner to use possession protection?

No. In a possession-interference case, what matters is only that you were in factual control of the property before the interference and that the interference happened without your consent. The court deliberately leaves the question of title aside at this stage.

What happens if I miss the one-year deadline for possession protection?

The possession route closes, but you don't lose your ownership rights — you're left with the vindication claim, which requires proving title to the property and usually takes longer.

Can I just remove my neighbour's belongings from the occupied part of my land myself?

We would advise against taking matters into your own hands — forcibly removing someone else's property yourself can itself be treated as an interference with their possession, even if the land actually belongs to you. The safer route is a written demand to vacate, and, if there's no response, the court.

Is it really true that a vindication claim never becomes time-barred?

As a rule, an owner's claims for the return of property and for the cessation of interference are not subject to limitation in the way ordinary property claims are — however, this is a complex area of law with exceptions and nuances, which is worth confirming with a lawyer in relation to your specific case, particularly if many years have passed.

If someone has been occupying my property for 25 years, can I still get it back?

That depends on whether the other person meets the conditions for adverse possession (among other things, sufficiently long, uninterrupted possession "as an owner"). The longer this situation continues without you taking action, the more seriously this risk needs to be taken — it's worth consulting a lawyer and reviewing your documentation as soon as possible.
