Marriage, Divorce and Ownership of Property in Poland

Buying property in Poland as a married couple where one or both of you live, or have lived, in the UK? Before you sign the notarial deed, there are two things worth understanding: which marital property regime applies between you, and — for a Polish-British couple — which country's law actually governs your marital assets in the first place. That determines whether the property becomes joint marital property or stays separate, and what happens to it if the marriage ends.

This guide is general legal information, not legal advice. How the rules apply depends on your individual circumstances, contracts, documents and deadlines. If you need advice or representation, the matter should be assessed by a qualified Polish lawyer. Twoja Sprawa helps you organise the documents for that assessment.

Marital property regime — what is joint, what stays separate

When a marriage is concluded, the spouses automatically become subject to statutory joint property (wspólność ustawowa) — a regime that, by operation of law, covers items acquired during the marriage by either spouse. This includes things like salary from work and income generated by joint or separate assets. In practice, if you buy a flat in Poland during the marriage using current income, it will generally form part of the joint marital property — regardless of whose name formally appears on the notarial deed and the księga wieczysta (the land and mortgage register, Poland's equivalent of an HM Land Registry title register).

A separate category is separate property (majątek osobisty) belonging to each spouse individually. This includes, among other things, items acquired before the marriage began, and items acquired by inheritance, legacy or gift — unless the person leaving the inheritance or making the gift stated otherwise. A "surrogation" rule applies here: if you buy Polish property using funds from your separate property (for example, an inheritance from parents in the UK, or savings from before the wedding), that property also becomes separate property, not joint — unless a specific provision says otherwise.

This distinction matters when planning a purchase:

Source of purchase funds Which property the purchase generally becomes
Current income from work in the UK during the marriage Joint marital property
Savings accumulated before the wedding Separate property (if documented)
Inheritance or gift received during the marriage Separate property
Proceeds from selling separate assets (surrogation) Separate property
Mortgage taken out jointly during the marriage Joint marital property (as a rule)

In practice, proving that a property was bought with separate funds can be difficult — especially if the money passed through a joint UK bank account before reaching Poland. If you want a clear separation, it is worth documenting the source of funds at the time of purchase (bank statements, a gift deed, or a certificate confirming inheritance).

Prenuptial agreements and buying property in Poland

Spouses may, by a contract executed as a notarial deed, extend or restrict statutory joint property, establish separate property, or establish separate property with equalisation of accrued gains. This marital property agreement (commonly called intercyza, sometimes loosely translated as a Polish prenup, though it can also be made after the wedding) can be entered into before or during the marriage, and can later be amended or terminated. Failing to use notarial form makes such an agreement void.

For couples buying property in Poland, an intercyza is often considered where:

Under separate property, each spouse retains both the property acquired before the agreement and the property acquired afterwards, and manages it independently — meaning a property bought by one spouse after separate property is established does not automatically become jointly owned. The equalisation-of-gains variant additionally gives the spouse whose assets (accrued gains) grew less a claim for equalisation once that regime ends — so even under formal separation, an unequal increase in wealth can still be financially reconciled between the spouses.

Whether to enter into an intercyza before buying property in Poland — particularly for a couple with assets on both sides of the Channel — requires an individual assessment by a lawyer, both as to the content of the agreement and as to which law actually applies to it (see below).

Which law governs the marital property of a Polish-British couple

This is the question most couples planning a Polish property purchase overlook — yet it determines whether Poland's Family and Guardianship Code (Kodeks rodzinny i opiekuńczy) applies to your assets at all.

Default rule without a choice of law (cascading conflict-of-laws rule). Where spouses do not share a common nationality (for example, a Polish national and a British national) and have not made a choice of law, their marital property relations are governed, in order, by: the law of the state of both spouses' habitual residence; failing that, the law of their common habitual stay; and, as a last resort, the law of the state with which they are most closely connected. A couple where one spouse is Polish and the other British, living together in Poland, may therefore be subject to the Polish statutory joint property regime despite their different nationalities — common residence, not nationality, decides the applicable law.

Choice of law. Spouses may deliberately choose the law applicable to their marital property relations — the national law of one of them, or the law of the place of residence or habitual stay of one of them, even before the marriage takes place. The marital property agreement itself (intercyza) is governed by the law chosen this way, or, absent a choice, by the law applicable at the time the agreement was made.

What this means for a UK-PL couple: a couple living in the UK may still be subject to English law for their property regime if that is where they share a habitual residence — affecting how assets are treated in a UK divorce. A couple who move back to Poland permanently may, over time, come under Polish conflict-of-laws rules as their habitual residence changes, unless they made an earlier choice of law. A deliberate choice of Polish law gives certainty that assets will be governed by the familiar regime under the Polish Family and Guardianship Code, regardless of where the couple later lives.

Establishing which law actually applies to a specific couple requires an individual assessment by a lawyer.

UK divorce and Polish property

Where spouses divorce before a court in England and Wales (or elsewhere in the UK), and one of the marital assets is a property located in Poland, two separate issues need to be kept apart:

1. The divorce order itself — an English court can grant a divorce and, as part of financial remedy proceedings, take the value of the Polish property into account when dividing the couple's overall marital assets (for example, awarding one party a larger share of UK-based assets in exchange for leaving the Polish property with the other). How an English court treats a foreign property within divorce financial proceedings is a matter of English family law, requiring separate advice from a solicitor in England and Wales.

2. The formal transfer or division of ownership in Poland — an English court order does not automatically change the entry in the Polish land and mortgage register (księga wieczysta). To transfer one spouse's share to the other, or to formally divide co-ownership, a separate step in Poland is usually needed: a notarial deed (where the parties agree) or Polish court proceedings for division of joint marital property, potentially involving recognition of the foreign order by a Polish court.

In practice, a divorce "sorted" in the UK usually does not conclude the property matter concerning the Polish asset — an additional step in Poland is typically required, depending on whether the parties have reached agreement or the matter goes to a Polish court.

Dividing joint marital property after divorce

Where a Polish property forms part of joint marital property governed by Polish law (because the Polish statutory regime applies — see the section on applicable law above), a number of rules apply:

For Polish-British couples, the key question is whether the Polish statutory regime applies to their assets at all — if English law is instead the applicable law (for example, because the couple lived in the UK throughout the marriage and never chose Polish law), the division rules may look quite different from those described above, even though the property itself is physically located in Poland.

Unmarried couples — different rules

An increasing number of couples buying property in Poland from the UK are unmarried. None of the joint marital property mechanisms above apply to them, since those are reserved for spouses. Instead:

For unmarried couples planning a purchase in Poland, it is particularly important to fix precise ownership shares in the notarial deed itself and — where contributions differ — to document that contribution, to avoid disputes if the relationship later ends. On the different ways of structuring joint ownership for Polish-British couples specifically, see our guide: Buying Property as a Polish-British Couple: Ownership Options.

Documents you will need

When planning a purchase or a division of property with a marital property regime in mind, it is worth having ready:

Common risks and mistakes

  1. Assuming a property registered in one spouse's name in the notarial deed belongs only to that spouse. Under statutory joint property, if the purchase was funded from current income, the property generally forms part of joint marital property regardless of whose name is on the deed.
  2. Overlooking the question of applicable law. Couples often assume Polish family law applies "automatically" because the property is in Poland — in fact, the marital property regime may be governed by the law of the state of common residence, which could be English law.
  3. Failing to document the source of funds when buying with separate assets. Without bank statements or a certificate of inheritance, it is later difficult to prove that a property did not form part of joint marital property.
  4. Treating a divorce granted in the UK as "settling" the Polish property. An additional formal step in Poland is usually required.
  5. Buying with an unmarried partner without written agreement on shares. On separation, unclear ownership shares lead to long and costly disputes.
  6. Delaying a marital property agreement until a conflict has already started. An agreement made calmly, before the purchase, is usually far easier to negotiate than one attempted mid-dispute.

Checklist

Frequently asked questions

Does property bought in Poland automatically become joint marital property? As a rule, yes, if statutory joint property applies between you and the purchase was funded from income earned during the marriage (such as salary). The exception is a purchase made with funds from separate property (inheritance, gift, pre-marriage savings) — that generally remains separate property, provided it can be documented.

Is a prenuptial agreement made in the UK valid for property bought in Poland? It depends on the form of the document and on which law governs your marital property regime. A Polish marital property agreement (intercyza) requires notarial form. Whether a document drawn up in the UK is recognised requires an individual assessment by a notary and a lawyer before the purchase — this cannot be resolved without reviewing the specific document.

Does a divorce granted in England automatically divide property in Poland? Not necessarily. An English court order may take the value of the Polish property into account in the overall settlement of marital assets, but the formal transfer of ownership or termination of co-ownership in Poland usually requires separate action — a notarial deed where the parties agree, or Polish court proceedings where there is a dispute.

Which law governs the marital assets of a couple where one spouse is Polish and the other British? Absent a choice of law, a cascading rule applies: the law of the couple's common habitual residence, failing that the law of their common habitual stay, and as a last resort the law of the state most closely connected to the couple. Spouses can also deliberately choose the national law of one of them, or the law of their place of residence — as a rule it is advisable to settle this formally rather than rely on the default rules.

Do unmarried couples buying a flat together in Poland have the same rights as married couples? No. Unmarried couples do not have joint marital property — the property is co-ownership in shares stated in the notarial deed. On separation there is no automatic right to "half" of the other party's assets; what matters is the formal co-ownership share, which either party can ask to have terminated at any time.

Can a court award unequal shares in joint marital property after divorce? Yes, but only for important reasons, on the request of one spouse, taking into account the degree to which each spouse contributed to creating the joint property — including the contribution made through raising children and running the household, not only financial input.

Should we sign a prenuptial agreement before buying property in Poland if we both work in the UK? It depends on your circumstances — including whether your financial contributions are broadly equal, whether you plan further purchases, and whether either of you runs a business. This decision is best made after speaking to a lawyer, ideally before the purchase rather than in the middle of an existing dispute.

Deadlines

A claim to terminate co-ownership (relevant both to unmarried couples and to former spouses after joint property has ended) does not become time-barred — it can be raised at any time. The division of joint marital property after divorce is also not, as a rule, subject to a rigid statutory deadline, though the longer it is delayed, the harder it tends to become to gather evidence of outlays and sources of funding — particularly where assets are spread between Poland and the UK. Deadlines specific to divorce proceedings in England and Wales (for example, time limits for applying for a financial remedy order after divorce) are a matter of English law and require separate advice from a solicitor in the UK.
