Polish inheritance law presents a structured but demanding framework for international business owners and families with assets in Poland. When a person dies leaving property, shares in a Polish company, or real estate in Poland, the succession process triggers a set of mandatory legal procedures that cannot be bypassed regardless of the deceased's nationality. The core risk is straightforward: failure to act within statutory deadlines or to understand the forced heirship rules can result in permanent loss of inheritance rights or unexpected liability for the deceased's debts. This article maps the legal framework, the main dispute mechanisms, the practical pitfalls for foreign heirs, and the strategic options available at each stage.
Polish succession law is governed primarily by the Civil Code (Kodeks cywilny), specifically Book IV covering inheritance, which spans Articles 922 through 1088. These provisions establish who inherits, in what order, and under what conditions. The Code distinguishes between statutory succession - where the law determines heirs in the absence of a valid will - and testamentary succession, where the deceased's documented wishes govern distribution.
Statutory succession follows a strict hierarchy. The first group consists of the spouse and children of the deceased, who inherit in equal shares, with the spouse receiving no less than one quarter of the estate. If children are absent, the second group - parents and siblings - enters. More distant relatives follow in subsequent groups. The state treasury (Skarb Państwa) acts as the ultimate statutory heir of last resort when no qualifying relatives exist.
A critical feature of Polish law is the concept of the reserved share (zachowek), regulated under Article 991 of the Civil Code. The reserved share is a monetary claim - not a right to specific assets - that protects certain close relatives even when a will excludes them. Descendants, a spouse, and parents who would have inherited under statutory rules are entitled to half of their statutory share, or two thirds if they are permanently incapacitated or minor children. This claim survives regardless of what the will says and can be enforced through court proceedings.
Poland applies EU Succession Regulation No. 650/2012 (Rozporządzenie UE w sprawie dziedziczenia) to cross-border estates. Under this regulation, the law of the country of the deceased's habitual residence at the time of death generally governs the entire succession. A Polish national habitually resident in Germany will have German law applied to their estate, while a German national dying in Poland will have Polish law govern succession. The regulation also introduced the European Certificate of Succession (Europejskie Poświadczenie Spadkowe), which allows heirs to assert their rights across EU member states without repeated national proceedings.
In practice, many international clients underestimate the interaction between the EU regulation and Polish domestic rules. A common mistake is assuming that a will drafted under English or American law will automatically govern Polish real estate or company shares. Polish notaries and courts will examine whether the will meets formal requirements under the applicable law and whether the reserved share claims of Polish-resident relatives have been addressed.
One of the most consequential decisions in Polish succession is whether to accept or reject the inheritance. Under Article 1012 of the Civil Code, an heir has three options: unconditional acceptance (przyjęcie proste), acceptance with benefit of inventory (przyjęcie z dobrodziejstwem inwentarza), or outright rejection (odrzucenie spadku).
The deadline for making this declaration is six months from the date the heir learns of their entitlement. Missing this deadline has a significant consequence: since a 2015 amendment to the Civil Code, failure to act within six months results in automatic acceptance with benefit of inventory, which limits the heir's liability for debts to the value of the inherited assets. Before this amendment, silence meant unconditional acceptance - a rule that caused substantial harm to heirs who inherited heavily indebted estates.
Acceptance with benefit of inventory is now the default and protects heirs from personal liability beyond the estate's value. However, this protection requires the preparation of an inventory list (spis inwentarza) by a court-appointed bailiff (komornik sądowy) or a private notarial inventory, which carries its own procedural requirements and costs. The inventory must be completed within a court-specified timeframe, typically several months.
Rejection of inheritance is irrevocable once made. It must be declared before a notary or a court. A rejected inheritance passes to the next statutory heir or, if the rejected heir has children, to those children. This creates a cascading effect that international families frequently fail to anticipate: rejecting an inheritance to avoid debts may inadvertently pass those debts to minor children, who then require a court's approval to reject on their behalf under Article 101 of the Family and Guardianship Code (Kodeks rodzinny i opiekuńczy).
Practical scenario one: a foreign national inherits a Polish apartment alongside significant mortgage debt from a parent. Without legal advice, they miss the six-month window. Under current law, they are deemed to have accepted with benefit of inventory, limiting their exposure. However, if the inventory reveals assets exceeding debts, they must manage the estate actively. If they had sought advice promptly, they might have structured a rejection to pass the estate to a sibling better positioned to manage it.

Establishing heirship formally is a prerequisite for exercising any rights over Polish assets. Polish law provides two parallel mechanisms: the notarial deed of succession certification (akt poświadczenia dziedziczenia) and the court declaration of succession (stwierdzenie nabycia spadku).
The notarial route is faster and available when all heirs agree and appear before the notary. A registered notary (notariusz) examines the documents, verifies the will if any, and issues a notarial deed that has the same legal force as a court ruling. The process typically takes one to three days if all documentation is in order. The deed is registered in the National Notarial Register (Rejestr Aktów Poświadczenia Dziedziczenia), making it immediately searchable and enforceable across Poland and, via the EU Certificate of Succession, across other EU member states.
The court route is necessary when heirs are in dispute, when a will is contested, or when not all heirs can be located or agree to appear together. The competent court is the district court (sąd rejonowy) of the last place of residence of the deceased in Poland, or, if the deceased had no residence in Poland, the court of the location of the estate assets. Proceedings are conducted in non-contentious civil procedure (postępowanie nieprocesowe) under the Code of Civil Procedure (Kodeks postępowania cywilnego), Articles 627 through 691.
Court proceedings for a straightforward succession declaration typically take three to six months. Contested cases, particularly those involving disputed wills or missing heirs, can extend to one to three years. The court examines all potential heirs, including those who may not have come forward, and publishes a notice calling on unknown heirs to appear. This procedural safeguard protects the integrity of the succession but adds time.
A non-obvious risk for international clients is the interaction between the Polish succession certificate and foreign asset registries. A Polish court declaration of succession does not automatically update the land register (księga wieczysta) or the company register (Krajowy Rejestr Sądowy). Separate applications must be filed with the relevant registry, each with its own procedural requirements and fees. Failing to update these registries leaves the heir unable to sell, mortgage, or transfer the assets.
Will disputes are among the most complex and emotionally charged proceedings in Polish succession law. The Civil Code recognises several grounds on which a will can be declared invalid, and the procedural path differs depending on the nature of the challenge.
Under Article 945 of the Civil Code, a will is void if it was made in a state of unconsciousness or disturbed mental state, under the influence of error that was material to its content, or under unlawful threat. These grounds must be established through evidence, typically including medical records, witness testimony, and expert psychiatric opinions. The burden of proof lies with the party challenging the will.
The limitation period for contesting a will on these grounds is three years from the date the claimant learned of the ground for invalidity, with an absolute bar of ten years from the date the will was opened and announced (ogłoszenie testamentu). Missing these deadlines extinguishes the right to challenge, regardless of the merits.
Formal defects in the will's execution also provide grounds for invalidity. A holographic will (testament własnoręczny) under Article 949 of the Civil Code must be written entirely by hand, dated, and signed by the testator. Any deviation - including a single typed word or a missing date - renders the will void. Polish courts apply these formal requirements strictly, and international clients who draft wills abroad without understanding Polish formal requirements frequently encounter this problem when the will is presented to a Polish court.
Practical scenario two: a Polish entrepreneur with significant company shares dies leaving a notarial will that divides the shares equally among three adult children. One child, who managed the business for a decade, challenges the will on the ground that the testator lacked mental capacity in the final months of life. The proceedings require expert psychiatric evidence, review of medical records, and witness testimony from employees and family members. The dispute delays any transfer of company shares, potentially disrupting business operations for the duration of the litigation.
A common mistake in such disputes is failing to seek interim measures (zabezpieczenie roszczenia) under Articles 730 through 757 of the Code of Civil Procedure. Courts can freeze assets, appoint an estate administrator (kurator spadku), or restrict transactions pending resolution of the dispute. Without interim measures, a co-heir in control of the estate may dissipate assets before the case concludes.

The reserved share (zachowek) is a distinctive feature of Polish succession law that frequently surprises international clients. Unlike forced heirship systems in some jurisdictions that give entitled heirs a right to specific assets, the Polish reserved share is a personal monetary claim against the heir or, in certain circumstances, against the donee of lifetime gifts.
Under Article 993 of the Civil Code, lifetime gifts made by the deceased are added back to the estate for the purpose of calculating the reserved share base. This means that a testator who gave away most of their assets during their lifetime cannot effectively disinherit close relatives by depleting the estate before death. Gifts made more than ten years before the testator's death to persons who are not statutory heirs are excluded from this calculation, but gifts to statutory heirs are included regardless of when they were made.
The reserved share claim is brought against the heir who received the estate under the will. If the heir is insolvent or the estate is insufficient, the claim can be directed against donees who received lifetime gifts, in reverse chronological order - the most recent gift first. This creates significant exposure for recipients of substantial lifetime gifts from Polish residents.
The limitation period for a reserved share claim is five years from the date the will was announced (Article 1007 of the Civil Code). This deadline is firm. Many entitled relatives delay action, assuming the matter can be resolved informally, only to find their claim time-barred.
Practical scenario three: a Polish businesswoman leaves her entire estate, including a Warsaw apartment worth approximately EUR 400,000, to a charitable foundation. Her two adult children, who would have inherited equally under statutory succession, each have a reserved share claim worth one quarter of the estate's value - approximately EUR 100,000 each. The foundation, as the heir, must satisfy these claims in cash. If the foundation cannot pay, the children may pursue the claim against recipients of lifetime donations the businesswoman made in her final years.
The business economics of a reserved share dispute deserve careful analysis. Legal fees for a contested reserved share case typically start from the low thousands of EUR and can reach the mid-five figures in complex matters involving business valuations. Court fees (opłata sądowa) are calculated as a percentage of the claim value. The procedural burden includes obtaining a professional valuation of the estate assets, which adds both cost and time. Against this, a successful claimant recovers a monetary sum that may significantly exceed the cost of proceedings.
A non-obvious risk is the interaction between the reserved share and estate tax (podatek od spadków i darowizn). The reserved share payment received by an entitled heir is subject to inheritance and gift tax under the Inheritance and Gift Tax Act (Ustawa o podatku od spadków i darowizn). The tax rate depends on the relationship between the claimant and the deceased and the value of the claim. Close relatives in the first tax group benefit from a full exemption if they notify the tax authority within six months of the claim becoming enforceable.
Polish law creates particular complexity when the estate includes shares in a Polish limited liability company (spółka z ograniczoną odpowiedzialnością, sp. z o.o.) or a joint-stock company (spółka akcyjna). Company shares are part of the estate and pass to heirs under general succession rules, but the company's articles of association (umowa spółki or statut) may contain restrictions on inheritance.
Under Article 183 of the Commercial Companies Code (Kodeks spółek handlowych), the articles of association of a sp. z o.o. may restrict the inheritance of shares or make inheritance conditional on the consent of the remaining shareholders. If the articles contain such a restriction and the shareholders refuse consent, the company must pay the heir the fair value of the shares within a prescribed period. Failure to pay within this period removes the restriction, and the heir becomes a full shareholder. This mechanism protects business continuity but requires careful attention to the articles of association at the time of succession.
For joint-stock companies, shares are freely inheritable unless the articles impose restrictions, which are less common. However, bearer shares (akcje na okaziciela) have been effectively abolished in Poland, and all shares must now be registered, simplifying the succession process but requiring updated shareholder registers.
International clients frequently encounter the problem of parallel proceedings. A Polish court handles the succession to Polish assets, while courts in another country handle assets located there. The EU Succession Regulation coordinates jurisdiction and applicable law within the EU, but assets in non-EU countries - such as the United Kingdom post-Brexit, Switzerland, or the United States - require separate proceedings under the law of each jurisdiction. Coordinating these parallel processes without a coherent strategy leads to delays, inconsistent outcomes, and unnecessary costs.
A further complication arises with real estate. Polish real estate passes to heirs automatically upon death under the principle of universal succession (sukcesja uniwersalna), but the heir's title is not effective against third parties until the land register (księga wieczysta) is updated. The application to update the land register must be filed by the heir and supported by the succession certificate. Until the register is updated, the heir cannot sell or mortgage the property, and the deceased's name remains on the register - creating practical problems if the estate administration is prolonged.
The competent authority for land register matters is the district court (sąd rejonowy) with jurisdiction over the location of the property. Electronic filing is available through the Polish court portal for certain applications, but succession-related land register updates typically require paper filing with original documents or certified copies.

What happens if a foreign heir misses the six-month deadline to accept or reject a Polish inheritance?
Under the current Civil Code rules, missing the six-month deadline results in automatic acceptance with benefit of inventory. This means the heir's liability for the deceased's debts is capped at the value of the inherited assets - the heir does not become personally liable beyond what they received. However, the heir must still cooperate with the inventory process and cannot simply ignore the estate. If the heir wishes to reject the inheritance after the deadline has passed, they must apply to the court to set aside the deemed acceptance, which requires showing a valid legal reason such as a fundamental error about the nature of the estate. Courts grant such applications rarely and only in well-documented circumstances.
How long does a contested inheritance dispute typically take in Poland, and what does it cost?
A straightforward court declaration of succession in an uncontested matter takes three to six months. A contested will dispute or a disputed reserved share claim can take one to three years at first instance, with appeals potentially adding another one to two years. Costs depend heavily on the complexity and the value of the estate. Legal representation fees typically start from the low thousands of EUR for simpler matters and can reach the mid-five figures for complex litigation involving business valuations or psychiatric expert evidence. Court fees are calculated as a percentage of the disputed value. The practical lesson is that early legal advice and, where possible, mediation or negotiated settlement significantly reduce both cost and duration.
Can a Polish reserved share claim be avoided through lifetime gifts or a foreign will?
Avoiding the reserved share through lifetime gifts is difficult because Polish law adds gifts back into the estate calculation for reserved share purposes, regardless of when they were made to statutory heirs. Gifts to non-heirs made more than ten years before death are excluded, but this requires long-term planning. A foreign will does not eliminate the reserved share if Polish law governs the succession - which it will if the deceased was habitually resident in Poland at the time of death under the EU Succession Regulation. A testator habitually resident outside Poland can choose Polish law to govern their succession by an express choice of law clause in the will, but this does not eliminate the reserved share under Polish law either. Genuine estate planning to minimise reserved share exposure requires early structural decisions, not last-minute arrangements.
Polish inheritance law offers a coherent but demanding framework that rewards early planning and penalises delay. The interaction between statutory succession, the reserved share, EU cross-border rules, and company law creates multiple points of risk for international families and business owners. Acting within statutory deadlines, understanding the forced heirship rules, and coordinating Polish proceedings with foreign jurisdictions are the three pillars of effective estate succession management in Poland.
