Recovering the Cost of Improvements to Jointly Owned Property in Poland
You replaced the roof, insulated the walls, or renovated the bathroom in a house you inherited jointly with your siblings — and now that the property is heading towards a sale or an estate division, your co-owner won't hand over their share of the costs? This is one of the most common flashpoints in Polish co-ownership disputes. This guide explains the difference between necessary and useful outlays, the principle used to settle them between co-owners, and how to prepare your evidence before the matter reaches a notariusz (a civil-law notary, ≠ a UK notary public) or a court.
This guide is general legal information, not legal advice. Whether — and how much — you can recover for outlays depends on the type of expense, whether the other co-owners agreed to it, the evidence available, and the specific facts of your case; we do not guarantee any outcome or settlement amount. If 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 — we help you organise the documentation for that assessment, while the legal assessment and representation is provided by a partner regulated adwokat or radca prawny (Polish advocate or legal counsel).
Key points
- Co-owners share expenses and benefits in proportion to their shares — this follows the principle set out in Article 207 of the Polish Civil Code.
- Outlays generally fall into two categories: necessary and useful — this distinction determines whether, and to what extent, reimbursement is available.
- Consent from the other co-owners makes settlement easier — an outlay agreed in advance (for example, by email) is far easier to prove than one made unilaterally, without consultation.
- Settling outlays typically comes up during estate division or when co-ownership is dissolved — the court can rule on co-owners' mutual claims within the same proceedings.
- Evidence is decisive — invoices, contracts with contractors, before-and-after photographs, and correspondence with co-owners all matter.
- Claims for reimbursement of outlays can become time-barred — so it is worth formally raising the claim without delay.
What counts as a necessary or a useful outlay on jointly owned property
In practice, expenditure on shared property is usually grouped into two main categories:
A Polish legal matter while you live in the UK?

Request a free initial assessment- necessary outlays — expenses required to keep the property in a condition that does not deteriorate (for example, repairing a leaking roof, replacing a faulty electrical installation, or treating a damp, mould-affected wall);
- useful outlays — expenses that are not essential to preserve the fabric of the building but increase its value or usefulness (for example, modernising a bathroom, insulating the external walls, or replacing windows with energy-efficient ones).
The line between the two is often blurred in practice — the same renovation project can be partly a necessary outlay (say, replacing a leaking roof) and partly a useful one (adding loft insulation at the same time). For this reason, on larger renovation projects it is worth splitting costs into separate line items from the planning stage, and keeping documentation for each of them.
The principle for settling outlays between co-owners
The starting point is the rule that co-owners bear expenses relating to the shared property in the same proportion as their shares in the co-ownership — Article 207 of the Polish Civil Code. In practice, this means that a co-owner who financed a renovation out of their own pocket can, as a general rule, claim reimbursement from the others in proportion to their respective shares.
What matters, however, is whether the expense fell within ordinary management of the shared property or went beyond it, and whether the other co-owners consented to it. An outlay made without the knowledge or consent of the other co-owners — particularly an expensive modernisation project — tends to be harder to recover than an expense that was agreed in advance. It is always worth securing written confirmation of consent before work begins.
Settling outlays in estate division and when ending co-ownership
The question of settling outlays most often resurfaces in two situations: when heirs are dividing an inherited property (dział spadku, estate division) and when co-owners decide to end their co-ownership (zniesienie współwłasności — by physically dividing the property, awarding it to one co-owner with a cash payment to the others, or selling it and dividing the proceeds). In both types of proceedings, the court can rule at the same time on the co-owners' mutual claims, including reimbursement of outlays already made.
This means that anyone who has spent years maintaining and renovating a shared property should raise their claim for reimbursement of outlays as early as the application for estate division or for ending co-ownership — not only after those proceedings have concluded, when it may already be too late, or considerably harder, to do so.
How to document outlays you have made
| Evidence | Role | Notes |
|---|---|---|
| Invoices and receipts | Prove the amount and nature of the expense | Keep originals or scans, ideally with a note describing the work |
| Contracts with contractors | Show the scope and timing of the work | Help distinguish a necessary outlay from a useful one |
| Before-and-after photographs | Show the property's condition and the extent of the changes | Worth dating them |
| Correspondence with co-owners | Evidence of consent (or its absence) for the renovation | Emails, texts, messages — keep the full history |
| Bank statements / transfer confirmations | Prove who actually paid for materials and labour | Important where payments came from one person's account |
| An expert valuation (rzeczoznawca) | May be needed if there is a dispute over the value of a useful outlay | Costly, but can be decisive in court proceedings |
Amicable settlement or court proceedings
- Talk it through and total up the costs together — before things become tense, it is worth sitting down and going through the expenses jointly.
- Prepare a written summary of outlays — with invoices and a description of which expenses you consider necessary and which useful.
- Propose a settlement — for example, deducting the value of the outlays from the co-owner's share of the sale proceeds, or from any cash payment made when ending co-ownership.
- Mediation, if discussions do not resolve the matter.
- Raise the claim within ongoing estate-division or co-ownership-ending proceedings — or, in some situations, bring a separate claim for payment.
Time limits and limitation periods
Like other financial claims, claims for reimbursement of outlays on jointly owned property can become time-barred. It is therefore not worth waiting years before formally raising a claim for reimbursement — the longer the delay since the outlay was made without any response from the interested co-owner, the harder it becomes to reconstruct the full history of expenses in court, and the greater the risk that part of the claim will already be time-barred.
Frequently asked questions
Can I claim reimbursement of outlays if I carried out the renovation without my co-owner's consent?
It depends on the nature of the expense and the circumstances — necessary outlays (for example, work that saves the building from further damage) are generally easier to recover even without prior consent, whereas for useful outlays, the absence of consent from the other co-owners can make it harder to recover the full amount.
Are outlays only settled when the property is sold?
No — settlement can also take place during estate division, when co-ownership is ended in another way (for example, the property being awarded to one co-owner with a cash payment to the others), or in separate proceedings if the co-ownership continues and the parties cannot reach agreement.
Are useful outlays always reimbursed in full?
Not necessarily — the amount recoverable depends on the circumstances, including how much the property's value actually increased as a result of the expense, not simply the amount shown on the invoice.
How do I settle outlays when the property is subject to estate division?
The best approach is to raise the claim for reimbursement of outlays in the application for estate division itself, attaching supporting documentation — the court can then rule on it together with the division of the estate, rather than forcing the heirs into a separate case.
Need help with this matter?
Settling outlays on jointly owned property can be difficult without well-organised documentation, especially where renovations dragged on for years and some expenses no longer have supporting invoices.
