Squatters or Unauthorised Occupants on a Polish Commercial Property: Urgent Steps to Evict and Prevent Adverse Possession (zasiedzenie)

Squatters unauthorised occupants polish commercial property situations demand decisive action within hours, not weeks. When a buyer, developer, lender or asset manager discovers that a warehouse, retail unit or brownfield plot is occupied without consent, the first days often determine whether possession can be recovered quickly, and whether the longer-term risk of zasiedzenie (adverse possession) can be neutralised before it ever matures. This guide sets out a time-sequenced emergency playbook anchored to the Polish Civil Code and the Code of Civil Procedure, covering immediate preservation steps, civil and criminal remedies, evidence strategy and preventative controls. It is written for commercial owners and institutional stakeholders who need practical, statute-linked direction they can act on today.

Purpose: immediate, practical guidance for company clients who discover unauthorised occupants on commercial property in Poland. The content below is action-oriented, grounded in primary Polish law, and designed to be used alongside qualified local counsel. This guidance is general in nature and does not constitute legal advice; where a situation is urgent, legal advice should be sought the same day.

1. Quick Action Checklist: The First 72 Hours (Emergency Playbook)

The opening phase is about preserving your legal position, not resolving it. Every action you take, or fail to take, becomes evidence later. The overriding rule is simple: document everything, interrupt the occupation lawfully, and avoid forceful self-help. Under Polish law, a possessor may use permitted self-help only within narrow statutory limits; beyond those limits, forceful action can expose you to liability.

• Secure the perimeter where it is safe and lawful to do so, do not use force against persons present.
• Document the occupation with dated, timestamped photographs and video.
• Obtain written witness statements from staff, neighbours, contractors or security personnel.
• Notify the police and your insurer, and record incident reference numbers.
• Preserve CCTV footage before it is overwritten.
• Locate and safeguard title documents and the land register extract.
• Serve a written notice on the occupiers recording your objection to their presence.
• Open a dated inspection log and continue regular site visits.
• Instruct counsel to prepare an urgent possession application and, if needed, an interim measure.

1.1 Documenting the Scene (Photos, Timestamping, Chain of Custody)

Evidence that an owner objected to the occupation and never acquiesced is one of the most important defences against a future adverse possession claim. Photograph entrances, interior conditions, any posted notices and signs of occupation. Ensure device timestamps are accurate, retain original files, and record who took each image and when. A consistent chain of custody, who held the footage, where it was stored, when it was copied, helps prevent challenges to authenticity if the matter reaches court.

A sample notice to occupiers can be short and factual: a statement identifying the property by its land register number, a declaration that the occupation is without the owner’s consent, a demand to vacate by a stated date, and a reservation of all legal rights. Serving such a notice and photographing it in situ records the owner’s objection, a relevant fact when possession is later assessed.

1.2 Safety and Police, When to Call Immediately

Call the police immediately where there is a risk to persons, criminal damage, a break-in, or threats. The Polish Penal Code (Kodeks karny) creates offences that may be engaged by forced entry or damage to property, and a police report both triggers any criminal process and generates an official record of the incident. However, owners should understand the limits: the police will frequently decline to remove occupants in what they treat as a civil dispute over possession, absent a clear criminal offence or a court order. Use the criminal route for what it does well, documenting events and deterring damage, while pursuing civil remedies in parallel for the actual recovery of possession.

1.3 Informing Insurers and Lenders

Most commercial property policies require prompt notification of events that affect the risk, including unauthorised occupation. Notify your insurer in writing within the policy’s reporting window and preserve the correspondence. Where the property is mortgaged, inform the lender early: a mortgagee has a direct interest in the asset, and delayed notification can complicate enforcement and later claims. These notifications are not bureaucratic formalities, they protect coverage and keep secured creditors aligned with your recovery strategy.

2. Who Are “Squatters” Versus “Unauthorised Occupants” Versus “Informal Tenants”?

The correct remedy depends heavily on the occupant’s legal status. Not everyone found on site is a trespasser. Some occupants may hold, or claim to hold, a licence or an informal tenancy, perhaps a former caretaker, a party to a lapsed lease, or someone who entered under an arrangement with a previous owner. Others are pure trespassers with no colour of right. In squatters unauthorised occupants polish commercial property cases, mislabelling an informal tenant as a trespasser can derail your claim and expose you to counterclaims.

2.1 Why Status Matters for Remedies

Where a contractual relationship exists or is credibly asserted, the dispute is governed by the law of lease or licence, and recovery usually proceeds through termination followed by a possession claim. Where there is no contractual basis at all, the matter is one of protection of possession and ownership under the Civil Code. The practical consequences differ sharply: evidentiary thresholds, applicable notice requirements and the speed of available relief all turn on this classification. Establishing status early, through document review, the land register and witness accounts, lets counsel select the fastest lawful route.

3. Immediate Civil Remedies, Eviction, Possession Orders and Interim Measures

Civil law is where possession is actually recovered. Polish procedure offers graduated remedies, from urgent interim relief through to final possession judgments enforced by a bailiff. The right combination depends on urgency, the strength of your documentary evidence and the occupant’s status.

3.1 Interim Relief: When to Apply and What Courts Expect

Where there is an urgent risk, ongoing damage, dissipation of assets, or escalating occupation, an application for a securing measure (zabezpieczenie) under the Code of Civil Procedure (Kodeks postępowania cywilnego) may obtain interim protection while the substantive claim is determined. The applicant generally must show a credible claim (the legal interest it seeks to secure) and a legal interest in granting the measure. Courts expect clear documentary support: proof of title, the land register extract, dated evidence of the occupation and, ideally, a served notice demonstrating the owner’s objection. Interim measures are decided more quickly than full proceedings, which is precisely why early, well-organised evidence matters.

3.2 Possession and Ownership Claims

Where a contractual relationship existed, for example, a lease that has been validly terminated, recovery proceeds on the basis that the right to possession is established by the contract and its termination. Where there is no contract, the owner relies on the ownership protections of the Civil Code and typically brings a claim for the release of the property (a rei vindicatio claim, powództwo windykacyjne), or, where appropriate, a possessory claim for the restoration of disturbed possession (powództwo o przywrócenie posiadania). The ownership claim requires proof of the owner’s title and the defendant’s possession without legal entitlement. Practically, the stronger and more complete your documentary record, the shorter and more predictable the proceedings become.

3.3 Enforcement: Komornik (Bailiff) Steps, Costs and Timelines

A possession judgment is not self-executing. Enforcement is carried out by a court bailiff (komornik) under the enforcement provisions of the Code of Civil Procedure. Once an enforceable title (tytuł wykonawczy) is issued, the owner applies to the bailiff, who schedules and executes the removal of occupants and restoration of possession. Timelines vary with court and regional caseloads, and enforcement carries its own costs, which are generally recoverable from the losing party but must be advanced. Factoring in the enforcement stage from the outset, rather than treating the judgment as the finish line, avoids delay at the most sensitive moment.

4. Criminal Law Options, When a Criminal Complaint Helps

Criminal proceedings can support a recovery strategy but rarely resolve possession on their own. Understanding this prevents owners from relying on the police to do what, in practice, only a civil court can order.

4.1 Typical Criminal Offences Used in Practice

The Penal Code addresses offences such as property damage and certain forms of unlawful interference with property, and these may be engaged where occupants have broken in, caused damage, or committed related wrongs. Filing a criminal complaint creates an official investigative record, can deter further damage, and occasionally prompts occupants to leave. Where damage or forced entry is ongoing, a prompt complaint is appropriate and complements the civil track.

4.2 Risks and Procedural Limits Versus Civil Routes

The criminal route has real limits. Investigations take time, prosecutors exercise discretion, and a criminal process does not deliver an enforceable order for the return of possession. The police will often treat the removal of occupants as a civil matter unless a distinct criminal offence is clearly made out or a court order exists. For squatters unauthorised occupants polish commercial property disputes, the reliable path to recovery remains the civil claim backed, where appropriate, by interim measures, with the criminal complaint serving as a parallel tool rather than the primary remedy. Forceful self-help eviction outside the narrow statutory limits is not permitted and can itself expose the owner to criminal and civil consequences.

5. Adverse Possession (Zasiedzenie) Under Polish Law, Statutes, Timeframes and Key Evidence

The reason urgency matters is zasiedzenie, acquisition of title by prescription, governed by the Polish Civil Code. In defined circumstances, a person who possesses real property as an owner (a possessor in good faith or bad faith), continuously and for the statutory period, may acquire title by operation of law. For owners of commercial assets, this is the latent risk behind a seemingly minor nuisance: prolonged, uninterrupted possession can, over time, threaten title itself. Addressing squatters unauthorised occupants polish commercial property early is therefore not only about recovering use of the site, but about protecting ownership.

5.1 How Possession Is Counted and Interrupted (Legal Acts, Notices, Re-Entry)

The statutory period for acquisition by prescription runs only while possession remains continuous, and its length depends on whether the possessor acquired possession in good or bad faith, with a longer period applying to possession in bad faith. The practical defence for an owner is interruption of the running of that period. The running of the prescription period can be interrupted by appropriate legal acts asserting ownership, in particular by commencing court proceedings aimed directly at recovering the property or otherwise at the asserted right.

Formal demands, served notices recording the owner’s objection and the owner’s resumption of control support the owner’s position evidentially, though the interruption of the prescription period itself turns on the acts recognised by the Civil Code and the controlling case law. The exact statutory periods and the precise tests for continuity, good faith and interruption should be confirmed against the current consolidated Civil Code and the case law of the Supreme Court (Sąd Najwyższy) for the specific facts at hand.

5.2 Common Factual Patterns That Create Danger

Certain scenarios recur. Long-abandoned warehouses and brownfield plots left unmonitored for years are classic sites where occupation can take root undetected. Former caretakers or informal arrangements that are never documented or terminated can evolve into possession claims. Acquisitions of distressed portfolios where due diligence overlooked who was actually on the ground are another frequent source of exposure. The common thread is absence of active ownership, no inspections, no records, no objection. Consistent, documented engagement with each asset is the surest way to keep any prescription clock from running.

6. Evidence Strategy: What Prevents an Adverse Possession Claim

Resisting a prescription claim is largely an evidentiary exercise. The owner’s goal is to demonstrate that the statutory conditions were never satisfied, in particular that possession as an owner was not continuous for the required period, and that ownership rights were actively asserted. Assemble and preserve:

• Title deeds and notarised acquisition documents.
• The land and mortgage register (księga wieczysta) extract confirming registered ownership.
• Lease and licence records, including terminations.
• CCTV footage and dated inspection logs.
• Police reports and incident references.
• Maintenance, utility and billing records showing the owner’s control.
• Letters of demand and served notices to occupiers.

6.1 Using Registered Land Records (Księga Wieczysta) and Notarised Documents

The księga wieczysta is the public land and mortgage register and a cornerstone of proof of title in Poland. An up-to-date extract establishes registered ownership and any encumbrances, and should be obtained promptly when occupation is discovered. Notarised acquisition documents corroborate the chain of title. Together with maintenance and billing records, these help establish that the owner exercised and asserted ownership. Sample notice wording should reference the register number precisely so that every objection is unambiguously tied to the property in question.

7. Third Parties: Lenders, Tenants, Service Providers and Sub-Occupiers

Recovery rarely involves only the owner and the occupant. In squatters unauthorised occupants polish commercial property matters, third-party interests can shape both strategy and timing, and ignoring them can create fresh liabilities.

7.1 Notifying Lenders and Commercial Landlords

A mortgagee holds a secured interest in the property and has a legitimate stake in its protection and value. Notify lenders promptly and in writing, keeping them informed of steps taken. Where the asset is itself leased from a superior landlord, that landlord’s rights and any notice obligations under the head arrangement must also be considered. Early, documented notification keeps secured creditors and superior interest-holders aligned and avoids disputes over whether the owner acted diligently.

7.2 Handling Competing Claims to Possession

Occupants sometimes assert rights through unknown sub-licences, informal sub-letting, or arrangements made with a previous owner. Utilities and contractors may also be on site under historic instructions. Before enforcement, map every person and entity claiming any right to be present, assess the basis of each claim, and address them in the correct order. Competing claims that are not resolved cleanly can stall enforcement or generate counterclaims, so identifying them early is part of a sound recovery plan.

8. Preventative Measures for Owners and Asset Managers (Policy and Contracts)

Prevention is far cheaper than recovery. The controls below reduce the chance of unauthorised occupation and, where it occurs, help ensure the owner already holds the evidence needed to respond.

• Conduct regular, documented site inspections, among the most effective deterrents.
• Maintain formal, current licence and tenancy records for every occupier.
• Operate strict lock and key control, and change access promptly when arrangements end.
• Include contractual anti-squat, re-entry and inspection clauses in leases and licences.
• Ensure insurance expressly addresses vacant and occupied property risks.

8.1 Standard Lease and Licence Clause Bank (Sample Wording)

Leases and licences for commercial property should reserve, in clear terms, the owner’s right of inspection on notice, an express right of return of the property on termination, restrictions on assignment and sub-letting, and an acknowledgement that any occupation beyond the agreed term is without consent. Precise clauses of this kind can convert what might otherwise be a contested factual dispute into a straightforward contractual recovery, shortening proceedings and reducing cost.

8.2 Property Management SOP for Discovered Occupation

Asset managers should hold a standing operating procedure that mirrors the 72-hour checklist: who to call, how to document the scene, which notices to serve, and when to escalate to counsel. A tested SOP removes hesitation at the moment it matters most and ensures that every site, across a portfolio, is handled consistently and defensibly.

9. Typical Timeline and Cost Expectations

Expectations should be realistic and framed as ranges, because court and bailiff caseloads vary regionally. Police attendance, where appropriate, is measured in hours. Interim securing measures can be resolved comparatively quickly relative to a full trial, though timing depends on the court. A full possession claim and subsequent enforcement by a bailiff generally run over several months, depending on complexity, the occupant’s conduct and local court capacity. Costs include court fees, counsel’s fees and bailiff enforcement costs; many are recoverable from the losing party but must be advanced. Court fees are set by the applicable fees legislation and should be confirmed for the particular claim, as should any up-to-date thresholds.

The decisive variable in both time and cost is often the quality of the evidence assembled in the first 72 hours.

10. What to Do Now

If you have discovered unauthorised occupation, act today: secure and document the site, notify the police and your insurer, preserve title and register records, serve a written objection, and instruct counsel to prepare an urgent possession application. Early, decisive action in squatters unauthorised occupants polish commercial property cases is what makes fast recovery, and resisting any future zasiedzenie claim, more achievable.
