Trespass to Land in Poland: Possessory Protection Explained

Has someone driven onto your plot while you were away and started using it as their own? Has a neighbour blocked off a passage you've used for years? Or did a former tenant, once their lease ended, simply change the locks and refuse to hand back the keys? In none of these situations do you first have to prove in court that you are the owner — Polish law protects the plain fact of possession, regardless of who ultimately holds legal title. Here's what counts as trespass to land under Polish law, how a claim to restore possession works, and why the deadline for bringing one is so short.

This guide is general legal information, not legal advice. We do not guarantee any outcome — whether a court finds that possession was disturbed, and how it weighs the evidence you present, depends on the specific facts, documentation and course of proceedings. Where you need advice or representation, the matter should be assessed by a qualified Polish lawyer. Twoja Sprawa is an information and coordination platform, not a law firm — it helps you organise the documentation for that assessment.

Key points

• Possessory protection covers the plain fact of possession (Article 342 of the Polish Civil Code, Kodeks cywilny — KC) — you don't need to prove ownership or good faith to rely on it.
• The claim to restore possession is available against anyone who disturbed possession without permission and without a legal basis (Article 344 KC).
• The deadline to file the claim is one year from the disturbance — once it passes, possessory protection is no longer available, regardless of the circumstances.
• This is a different matter from an ownership (rei vindicatio) claim — there you must prove title; here it's enough to show that an established state of possession was disturbed.
• A possessory court, by design, disregards the question of legal title — it examines only the last peaceful state of possession and whether it was disturbed without permission.
• The sooner you react and document the disturbance, the easier it will later be to show the court what the situation looked like before it happened.

What counts as unauthorised disturbance of possession (Article 342 KC)

The starting point is Article 342 of the Civil Code, which sets out a general prohibition on disturbing someone else's possession without authorisation — regardless of whether the possessor is also the owner. The rule protects the factual state of holding a thing, not the question of who ultimately has the legal right to it.

Typical examples of a disturbance of possession include: entering land and beginning to use it without the existing possessor's consent, blocking access to a plot (e.g. fencing off a right of way), unilaterally changing the locks on premises previously held by someone else, or shifting a boundary fence and taking over a strip of someone else's land.

The key word is "unauthorised" — meaning without the possessor's consent and without a legal basis justifying the interference.

The claim to restore possession (Article 344 KC)

Under Article 344 of the Civil Code, a possessor whose possession has been disturbed without authorisation is entitled to a claim for restoration of the previous state and cessation of further disturbance. In practice, this means your claim can ask the court to order the disturber to leave the occupied land, remove a relocated fence, or restore access to a right of way — plus an injunction against repeating similar conduct.

As a rule, these cases are heard by the district court (sąd rejonowy). A defining feature of this type of proceedings is that the court, by design, examines only the fact of the last peaceful possession and whether it was disturbed — it does not decide who actually owns the property. Even if the defendant claims to hold a stronger title to the disputed land, that question generally stays outside the court's assessment in this type of case — it belongs instead to a separate ownership (rei vindicatio) claim.

The one-year deadline for a possessory claim — when it runs and why it's so short

A claim for protection of disturbed possession is subject to a one-year time limit running from the moment of the disturbance. That is considerably shorter than in most civil matters: possessory protection is meant to be a quick, provisional response to a disturbed factual situation, not a substitute for a lengthy dispute over ownership.

The clock runs from the event itself, not from when you gathered evidence or consulted a lawyer. Where the disturbance is repeated or ongoing, working out exactly when the deadline starts can be more complex. Once the year has passed, the possessory route closes — that does not mean you lose any ownership right you may have, but you are then left with the longer route of an ownership (rei vindicatio) claim. This is exactly why acting quickly matters when possession has been disturbed.

Possessory claim vs ownership claim — what's the difference

A possessory claim is often confused with an ownership (rei vindicatio) claim for the return of the property (Article 222 § 1 KC) — these are two separate legal tools, covered in more detail in our guide Unlawful occupation of land: possessory protection and the ownership claim. The key differences:

You can pursue both routes independently — if the one-year deadline hasn't yet passed, it's usually worth reaching for the faster possessory protection first, while separately preparing for a case over the return of the property, especially where legal title to the land is disputed.

Documents and evidence worth gathering

Common mistakes

1. Delaying your response. The deadline for a possessory claim runs from the moment of the disturbance, not from when you decide to act.
2. Taking matters into your own hands to forcibly retake possession. This can itself be treated as your own disturbance of the other party's possession.
3. Failing to document the state of the property before the disturbance. Without photos or witnesses, it's hard to show the court what things looked like beforehand.
4. Confusing a possessory claim with an ownership claim, even though they are governed by different evidential rules.
5. Relying only on a police report. It's the civil court that ultimately decides on restoring possession.

Step by step

1. Document the disturbance immediately — photos, date, description of the circumstances, witnesses' details.
2. Check how much time has passed since the disturbance — this determines whether the one-year deadline is still running.
3. Consider reporting it to the police or municipal guard, particularly for a sudden or forcible disturbance.
4. Send the person who disturbed your possession a written demand to restore the previous state — with proof of delivery.
5. File a claim for protection of disturbed possession with the district court, if you're still within the one-year deadline.
6. If the one-year deadline has already passed — check whether you hold a right of ownership that would support an ownership (rei vindicatio) claim instead.

Frequently asked questions

Do I have to be the owner of the property to seek possessory protection?

No. As a general rule, possessory protection is available to any possessor — what matters is the fact of actually holding the property, not legal title to it.

What happens if I miss the one-year deadline for a possessory claim?

The possessory route closes, but if you hold a right of ownership, you may consider an ownership (rei vindicatio) claim for the return of the property — a different procedure, which requires you to prove legal title.

Can I remove the person who disturbed my possession myself?

We would advise against taking matters into your own hands — doing so may itself be treated as your disturbing the other party's possession. The safer route is a written demand, followed by court proceedings if there's no response.

How is this different from an eviction case?

Eviction usually concerns someone who moved in under a lease or other title that has since ended. A possessory claim concerns an unauthorised disturbance of an existing factual state of possession, regardless of whether any legal title ever existed.

Need help with this?

If someone has disturbed your possession of a property without authorisation and you're wondering whether you're still in time to use possessory protection, it's worth organising your documentation and timeline of events before the one-year deadline runs out. Describe your situation — we'll review it free of charge — tell us when the disturbance happened and what evidence you've already gathered. Submitting the form does not create any contract.
