Water damage to an apartment in Poland – liability, compensation and legal assistance

What should you do after water damage, and who should you notify?

Alongside documenting the damage, you should notify the building’s property manager or the management board of the property owners’ association as soon as possible. Describe what happened, when you discovered the problem and which parts of the apartment have been affected.

There is no single mandatory notification method applicable to every association. However, keeping a written record of your report is the safest approach. Email is usually a quick and practical option. Where appropriate, you can also send a signed letter and retain proof of delivery.

Some associations provide dedicated email addresses for maintenance problems and emergencies. These may be listed on the building’s residents’ portal or noticeboard.

Do not delay reporting the incident while trying to establish its precise cause. You can provide further information once the property manager or a technician has inspected the problem.

How should you document water damage to your apartment?

The quickest way to record the damage is to take clear photographs and videos showing its location and extent. Keep both general views of the affected rooms and close-up images of individual defects.

Documents showing the apartment’s condition and the value of damaged items can also be useful, particularly where the apartment has recently been renovated or furnished. These may include receipts, invoices and photographs taken before the incident.

Ask the property manager or the association’s management board to arrange an inspection and prepare a written incident report, commonly referred to in Polish as a protokół zalania.

The report should record:

• the date of the incident and the inspection;
• the people attending the inspection;
• the rooms and belongings affected;
• visible signs of water penetration;
• any emergency measures taken to prevent further damage;
• the identified cause of the leak, if established, and the basis for that finding, such as a plumber’s inspection.

A report should distinguish between a confirmed cause and an initial assumption about where the water came from.

Can the cost of a private expert report be included in your compensation claim?

Many apartment owners instruct an independent specialist to inspect the property and assess the extent and value of the damage.

The cost of a private technical report or repair estimate may also be recoverable where commissioning it was objectively justified and necessary to establish liability or quantify the compensation due, and the amount charged was reasonable.

In its resolution of 2 September 2019, case no. III CZP 99/18, a seven-judge panel of the Polish Supreme Court confirmed that the cost of a private expert opinion may be recoverable where the opinion was necessary to pursue compensation effectively.

That resolution concerned compulsory motor liability insurance. However, its reasoning, based on general principles of compensation, may also support a claim for reimbursement of an expert report concerning water damage to an apartment.

Reimbursement is not automatic. You must explain why the report was needed, show that its cost was reasonable and establish its connection with the damage.

How can you establish the cause of water damage?

As far as reasonably possible, you should establish what caused the leak and who was responsible for the affected installation or building element. A technical inspection will often be necessary.

The property owners’ association is responsible for the proper maintenance and repair of the common property. Depending on the building and the function of the particular element, this may include structural components, roofs, gutters, external walls, shared water and drainage stacks, and communal heating installations.

However, the association is not responsible for every plumbing failure in the building.

If the leak originated in a shared part of the property, the association may be liable, provided the legal requirements for liability are met. In particular, it may be necessary to establish a causal connection between inadequate maintenance of that shared element and the damage to your apartment.

Who is liable for water damage: the property owners’ association, a neighbour or a contractor?

One of the most common mistakes is assuming that the property owners’ association must pay simply because the damage occurred in a building it manages.

Identifying the responsible party requires an assessment of the source of the leak and who had a duty to maintain the relevant equipment, installation or part of the building.

Each case requires an individual assessment, including the conduct of the person or organisation against whom the claim is being considered.

Fault may also be relevant. In its judgment of 5 September 2019, case no. V ACa 450/19, the Warsaw Court of Appeal discussed both the objective and subjective elements of fault. Broadly, this involves examining whether the conduct fell below the required standard and whether the person concerned can be blamed for it. Fault may involve intentional conduct or negligence.

For water damage claims, this means that identifying the apartment or pipe from which the water escaped may not be enough. It may also be necessary to establish why the failure occurred and whether a particular person’s negligent act or omission caused the damage.

The case concerned a claim for compensation for water damage considered under Article 415 of the Polish Civil Code.

Liability of the property owners’ association

A claim against the property owners’ association may be justified where the leak originated in the common property.

Examples include defective shared water or drainage stacks, roof leaks, poorly maintained façades, gutters, or other installations serving the building’s owners collectively.

However, a defect in a shared element does not automatically establish liability. The claimant should demonstrate that the damage resulted from inadequate maintenance of the common property or another failure attributable to the association.

Liability of a neighbour

If the water escaped from equipment or installations within a neighbouring apartment, such as a washing machine, dishwasher, damaged supply hose or leaking fitting, the claim may need to be directed against the owner or occupier responsible for the incident.

The same may apply where a tap was left running or the damage resulted from incorrectly performed renovation work or alterations to plumbing.

It is important to establish who was responsible for the relevant act or omission. Ownership of the apartment alone does not necessarily establish liability for everything that happens inside it.

Liability of a building or renovation contractor

Water damage may result from defective construction or renovation work, such as inadequate waterproofing, incorrectly installed pipework, defective roof repairs or work that departed from the design.

Depending on the circumstances, the contractor may be liable for the damage. This can include defects discovered after the work has been completed.

In some cases, the injured party may bring a claim directly against the contractor. In others, the association or apartment owner may be liable to the injured party and subsequently seek reimbursement from the contractor.

When will an insurer pay compensation for water damage?

If the responsible party has liability insurance, it may be possible to claim directly against their insurer. Relevant cover may be included in an apartment owner’s home insurance or in a liability policy held by the property owners’ association.

Another practical option may be to report the damage under your own home insurance policy, depending on the cover you purchased.

After paying compensation, your insurer may seek reimbursement from the party responsible for the damage.

How do you report a water damage claim and prepare a formal demand for payment?

A well-prepared claim should include evidence of the incident, its cause, the damage suffered and the basis for holding the recipient responsible.

Where the claim is directed against the property owners’ association, evidence of failures in maintaining the common property can be particularly important.

An inspection report prepared shortly after the incident is often useful. Where possible, it should be signed by the people who attended, including the property manager or the association’s representative.

If liability or the amount claimed is disputed, an independent building expert’s assessment can help establish the technical cause and reasonable repair costs. The assessment may support a formal pre-action demand for payment, known in Poland as a wezwanie do zapłaty.

The demand should identify the claim, explain its factual and legal basis, specify the amount sought and set a payment deadline.

If payment is not made, you may consider bringing court proceedings. Where the dispute involves technical questions, it will often be appropriate to request evidence from a court-appointed expert.

The court may require an advance payment towards the expert’s fees.

What can compensation for water damage cover?

Your claim should identify the losses caused by the incident and provide a reasoned calculation of the amount sought.

Under Article 363 § 1 of the Polish Civil Code, compensation generally takes the form, at the injured party’s choice, of either restoring the previous condition or paying an appropriate sum of money.

However, if restoring the previous condition is impossible or would impose excessive difficulties or costs on the liable party, the claim is limited to monetary compensation.

Depending on the circumstances and available evidence, the claim may concern the cost of repairing damaged finishes, replacing damaged belongings and other losses caused by the leak. Each item should be supported by evidence explaining both its value and its connection with the incident.

How do you prove liability and the amount of your loss?

In water damage cases, establishing the extent of the damage is only part of the task. You must also show why the particular defendant is legally responsible.

The person seeking compensation generally bears the burden of proving the facts supporting the claim. Preserving evidence from the outset can therefore make a significant difference.

The key issues usually include:

• whether damage occurred and what it involved;
• where the water came from and what caused the leak;
• why the defendant is responsible;
• the causal connection between the relevant act or omission and the damage;
• the amount of the loss.

Documents and recordings produced shortly after the incident are often particularly useful. These include photographs, videos and inspection reports prepared by the property manager, association representative, insurer or independent expert.

Where the cause is disputed, specialist technical evidence may be essential. For example, a court may appoint a building or plumbing expert to determine whether the leak originated in an individual apartment or in shared pipework, the roof or another common element.

Evidence supporting the amount claimed may include repair estimates, renovation invoices, material costs, expert valuations and documents from the insurer’s claims file.

Proof that an apartment was flooded does not, on its own, establish a right to compensation from a particular party.

For example, if the claim concerns a poorly maintained roof, it will be necessary to connect the association’s maintenance failures with the water damage.

The earlier you preserve reliable evidence of the cause and consequences, the easier it will generally be to assess and pursue the claim.

Private expert report or court-appointed expert: when do you need each?

Establishing the cause of water damage often requires specialist knowledge of construction, plumbing or building maintenance.

A private technical report is particularly useful before court proceedings, but it does not replace an expert opinion commissioned by the court where such evidence is needed.

You can instruct a suitably qualified building surveyor, engineer or other specialist to investigate the source of the leak, record the damage and estimate repair costs.

A reliable report can provide valuable support in negotiations with an insurer, neighbour or property owners’ association. It may help resolve the dispute without litigation.

If the case goes to court and technical issues remain disputed, a court-appointed expert’s opinion may become central to the proceedings. The expert assists the court with matters requiring specialist knowledge, such as the condition of pipework or the relationship between a defect and the resulting damage.

A private report can still be useful during litigation. It may help identify issues requiring expert examination, expose weaknesses in the other party’s position or provide a basis for questions and objections concerning the court-appointed expert’s findings.

How should you preserve evidence before repairing the apartment?

Start by taking detailed photographs and videos of all affected areas. Record both the overall condition of each room and specific damage, including damp walls, staining, loose plaster, damaged floors, furniture and appliances.

It is also sensible to document changes over the following days, as some consequences of water penetration become visible gradually.

Arrange a written incident report where possible. It should identify the date, the apparent or confirmed cause of the leak and the visible damage. Ask the people attending the inspection to sign it.

Keep all correspondence and documents relating to the incident, including communications with the property manager, association, insurer and the occupier of the apartment from which the water escaped.

Retain receipts, invoices and estimates for emergency measures and repairs.

In more complex cases, particularly where the cause is disputed, consider an independent technical inspection before substantial repairs begin. An expert can record conditions that may no longer be visible once damaged materials have been removed.

If repairs are likely to destroy important evidence, it may be appropriate to apply to a Polish court for evidence to be preserved before the main proceedings begin. This procedure may allow an inspection or expert examination to take place before the compensation claim is filed.

The evidence gathered may also support a later application for interim relief by helping substantiate the claim.

How much does a water damage compensation case cost in Poland?

Before starting court proceedings, assess both the merits of the claim and the likely cost of pursuing it.

Costs may include the court filing fee, expert evidence and legal representation. You should also consider the possibility of having to reimburse the other party’s recoverable litigation costs if the claim is unsuccessful.

Court filing fee

The court fee for filing a payment claim generally depends on the value of the claim.

Repair costs, replacement belongings and other monetary losses included in the claim will generally contribute to the amount used to calculate the filing fee.

For example, the standard filing fee for a claim of PLN 10,000 is generally PLN 500, while for a claim of PLN 15,000 it is generally PLN 750.

Expert fees

A court-appointed expert’s opinion can be one of the most significant expenses, particularly if the parties dispute the cause of the leak or the repair costs.

The court may require an advance towards the expert’s remuneration. Its amount will depend on the complexity of the issues and the inspections and analysis required.

Supplementary opinions may generate additional expenses. However, expert evidence can be decisive where the dispute involves technical questions.

Legal fees

You may represent yourself in Polish civil proceedings, although legal assistance can be particularly helpful in more complex cases.

Legal fees depend on the complexity and value of the case and the scope of the lawyer’s work.

For a foreign apartment owner, assistance may be especially useful when identifying the correct defendant, assessing Polish technical and insurance documents, or challenging an insurer’s refusal to pay.

The risk of paying the other party’s costs

Under the general rules on litigation costs, the losing party may be required to reimburse the successful party’s recoverable costs.

These may include:

• recoverable legal representation costs;
• expert expenses;
• court fees;
• other necessary litigation expenses.

If the claim succeeds only in part, the court may apportion costs between the parties. The amount recoverable for legal representation does not necessarily equal the full fee agreed with a lawyer.

Before filing a claim, review the evidence, the likely amount recoverable and the prospects of establishing liability against the proposed defendant.

A properly prepared demand for payment or insurance claim may resolve the matter without litigation. Where court proceedings are necessary, a well-supported claim may allow you to seek compensation, applicable interest and reimbursement of recoverable litigation costs.

How long do you have to report water damage to an insurer?

The deadline for notifying the insurer is different from the limitation period for bringing a claim.

Your insurance policy or its general terms and conditions, known in Poland as ogólne warunki ubezpieczenia or OWU, may require notification within a specified period, sometimes a few days. There is no single notification deadline that applies to every home insurance policy.

The safest approach is to report the damage promptly after discovering it and retain confirmation of your report.

You do not need to wait until the repairs are complete or every invoice is available. Supporting documents can generally be provided during the claims process.

Missing a notification deadline does not automatically mean that you lose your entitlement to compensation.

Under Article 818 § 3 of the Polish Civil Code, reducing the insurance payment on this basis requires an intentional breach of the notification duty or gross negligence. The breach must also have contributed to an increase in the damage or prevented the insurer from establishing the circumstances and consequences of the incident. Late notification alone is therefore insufficient to justify reducing compensation.
