Inheritance Rights Step by Step: Who is Entitled, How to Calculate and Recover – 30 Proven Tips (2026)

A parent transferred a house to one of the children, and the will excludes the rest of the family? The law does not leave you with nothing: inheritance rights are a minimum share in the estate of close relatives guaranteed by the Civil Code – which cannot be "circumvented" by a will or (in most cases) gifts. The problem is that ignorance can cost real tens, and in the case of real estate, even hundreds of thousands of zlotys: people miss the 5-year statute of limitations, sue the wrong parties, fail to account for gifts from years ago, or sign "waivers" they do not understand. This guide is a complete, verified instruction based on legal provisions: who is entitled to inheritance rights, how to calculate it down to the last zloty, from whom and in what order to demand money, what the court process looks like, and taxes – plus 30 proven tips at the end.

Last verification: July 21, 2026. Informational material – not legal advice. Inheritance rights cases can be evidentially complex; for large amounts, consult a lawyer (the first consultation often costs less than one procedural error).

In Brief

Step 1: Check if You Have Inheritance Rights

• Only descendants, spouse, and parents of the deceased are entitled – and only if they would be called to inherit by law in a specific situation (art. 991 § 1 KC). Examples: parents have inheritance rights only if the deceased left no children; grandchildren – if their parent (the deceased's child) did not survive the opening of the estate.
• Not entitled: siblings, extended family, unmarried partners, divorced spouses (and those in a declared separation), as well as individuals who renounced the inheritance, waived inheritance by notarial agreement, were deemed unworthy, or effectively disinherited.
• You are entitled to inheritance rights if you did not receive the due value in any form: gifts from the deceased, appointment to the estate, bequests, and since 2023 also benefits from a family foundation or assets from its dissolution (art. 991 § 2 KC). If you received part – you demand supplementation.

Step 2: Calculate Inheritance Rights – By the Numbers

1. Determine the "calculable" statutory share

   What fraction of the estate would be allocated to you in statutory inheritance. Note art. 992 KC: when calculating this, unworthy individuals and those who renounced the inheritance are included, while those who waived inheritance and disinherited individuals are excluded.

2. Apply the inheritance fraction

   × 1/2 (the principle) or × 2/3 if you were a minor or permanently disabled at the time of the opening of the estate.

3. Determine the inheritance rights base

   Net value of the estate (assets minus estate debts) + added gifts + bequests, and since 2023 also the founding fund contributed to the family foundation and assets from its dissolution – with their own time limits (art. 993–994¹ KC). Ordinary bequests and instructions are not deducted.

4. Properly account for gifts

   Do not include: small customary gifts and gifts to third parties made more than 10 years ago. Gifts to heirs and those entitled to inheritance rights (e.g., a house transferred to a daughter 20 years ago) are always included (art. 994). Valuation: the state at the time of the gift, prices at the time of determining inheritance rights (art. 995) – renovations made by the donee do not increase the base, but market price increases do.

5. Subtract what you have already received

   Gifts from the deceased and bequests made to you count towards your inheritance rights, and for descendants – also costs incurred by the deceased for upbringing and education exceeding the average measure (art. 996–997).

Step 3: Determine From Whom to Demand Money (Order!)

1. First, heirs

   You direct the claim to those who inherited the estate (art. 991 § 2). An heir entitled to inheritance rights is only liable for the excess over their own inheritance rights (art. 999).

2. Then, legatees

   If the heirs cannot provide the due amount – those who received specific assets by bequest are liable: jointly, within the limits of their enrichment, with the possibility of discharging themselves by returning the bequest (art. 999¹ KC). The family foundation is also part of the chain if the deceased contributed assets to it.

3. Finally, donors – from the last gift

   The donor is only liable within the enrichment from the gift added to the estate, and a previous donor is only liable if the later donor cannot provide supplementation (art. 1000–1001). They can discharge themselves from the obligation by returning the gifted item.

Step 4: Negotiate – and If Necessary, Go to Court

• Written demand for payment (amount + calculation + deadline + account number) opens negotiations and builds documentation. Most family matters end in a settlement – judicial, notarial, or mediated.
• Beware of the statute of limitations during negotiations: since June 30, 2022, a call for a settlement and mediation only suspend the statute of limitations for the duration of the proceedings (art. 121 points 5–6 KC) – they do not interrupt it and do not provide "new 5 years." Many online tips about "interrupting the statute with a call" are outdated.
• Lawsuit: you file the case against the obligated parties in the court of the last ordinary residence of the deceased – this is exclusive jurisdiction (art. 39 KPC), and you have no choice of another court. District court for disputes up to 100,000 PLN, regional court for amounts above (art. 17 point 4 KPC).
• Court fee: up to 20,000 PLN – fixed thresholds from 30 to 1,000 PLN; above – 5% of the dispute value, maximum 100,000 PLN (limit reduced from 200,000 PLN since September 23, 2025 – art. 13 u.k.s.c.). In difficult financial situations, you can apply for exemption from costs (art. 102).
• Evidence: notarial deeds of gifts (copies – can also be requested by anyone who demonstrates a legal interest), land and mortgage registers, estate documents; the value of the disputed property is determined by a court expert (a private appraisal is a good starting point for negotiations).
• Interest: demand statutory interest for delay from the demand/lawsuit – in a multi-year process, this amounts to significant sums.

Defense Against Inheritance Rights – What the Other Party Can Do

• Disinheritance (art. 1008–1011): only in a will and only for three statutory reasons (persistent living contrary to social coexistence principles against the will of the deceased; crimes against life, health, freedom, or gross insult to the deceased/close relatives; persistent failure to fulfill family obligations). The reason must be stated in the will, and forgiveness nullifies it. Key point: descendants of the disinherited retain their own inheritance rights – disinheriting a son does not take away inheritance rights from grandchildren!
• Unworthiness to inherit (art. 928): the court rules at the request of a person with an interest (within a year of learning, maximum 3 years from the opening of the estate); an unworthy person is treated as if they did not survive the estate – they also lose inheritance rights. Since November 15, 2023, the reasons have been expanded to include persistent evasion of alimony specified by ruling/agreement/contract and the obligation to care for the deceased.
• Installments, deferral, reduction (art. 997¹ KC, since May 22, 2023): any obligated party can request a deferral of the payment deadline or installment of the inheritance rights (up to 5 years; the court may extend it to 10 in special cases), and in exceptional cases – reduction, considering the situation of both parties. If the circumstances for reduction cease, the entitled party may demand the difference within 5 years.
• Art. 5 KC (abuse of rights): exceptionally, the court may reduce inheritance rights if the demand is grossly contrary to the principles of social coexistence (e.g., the entitled party harmed the deceased for years) – case law applies this cautiously.
• Life estate instead of a gift: property transferred by a life estate agreement (paid) is not included in the base – lawful planning, which we discuss in the guide on gifts and life estates.
• Waiver (art. 1048): by notarial agreement with the deceased, one can waive inheritance (including inheritance rights), and since 2023 also the right to inheritance rights – in whole or in part (art. 1048 § 2). Note: the waiver also includes your descendants unless otherwise agreed (art. 1049) – do not sign it "for peace of mind" without understanding the consequences.

Inheritance Rights Tax

• Received inheritance rights are subject to inheritance and gift tax (art. 1 ust. 1 pkt 5 of the inheritance tax act); the obligation arises at the moment of satisfaction of the claim (receipt of money/property).
• Closest family pays zero – provided they submit SD-Z2 within 6 months of receiving the inheritance rights (art. 4a; delay = tax as group I; from January 7, 2026, it is possible to apply for reinstatement of the deadline in the absence of fault).
• On the other side: paid inheritance rights reduce the tax base for the heir (art. 7 ust. 3 of the inheritance tax act), and when selling inherited property, it is an expense in PIT (art. 22 ust. 6d) – even if paid after the sale. Paying inheritance rights? Keep receipts.

30 Proven Tips

Before You Do Anything

1. Precisely determine the circle of statutory heirs – this affects your share.
2. Obtain a copy of the will and the protocol of its opening – the 5-year statute of limitations runs from the announcement.
3. List all known gifts from the deceased over the last decades – even those "long ago, so they don't count" (for family, they always count).
4. Check the land and mortgage registers of the deceased and the donees (ekw.ms.gov.pl – sections II and III will show gifts and life estates).
5. Do not sign any "family settlement statements" without a lawyer.
6. Renouncing the inheritance also means losing inheritance rights (the renouncer is treated as if they did not survive the estate – art. 1020 KC). In the case of an estate with debts, consider accepting it with the benefit of inventory instead of renouncing if you expect inheritance rights from the donees – consult the order of actions.
7. Gather evidence of your relationship with the deceased (care, contacts) – this will be useful in case of claims under art. 5 KC or disinheritance.
8. Calculate inheritance rights in two variants (cautious and full) – for negotiations and for the decision to sue.
9. Check if you are not among the "disinherited" – and whether the reason in the will is true and specific.
10. If you are a minor or permanently disabled entitled party – your share is 2/3, not 1/2.

Calculating and Gifts

1. Value properties at current prices, but in the state at the time of the gift – deduct expenses incurred by the donee.
2. Do not forget about estate debts – the base is calculated from the net value of the estate.
3. Include legacies as gifts.
4. Check "sale" agreements within the family for symbolic amounts – fictitious agreements can be challenged as hidden gifts.
5. Life estate ≠ gift: properties from a life estate cannot be included – but investigate whether the agreement was genuinely executed.
6. Deduct from your claim gifts you received from the deceased – omitting them is asking for a partial loss.
7. Life insurance policies with beneficiaries and funds from OFE/ZUS sub-accounts do not enter the estate – do not include them in the base.
8. Document values at the time of determining inheritance rights – update old valuations before the hearing.
9. With multiple donees, remember the order: demand first from the last one.
10. The donee can "return the item" instead of paying – prepare for this scenario (what will you do with your share in the apartment?).

Procedure, Deadlines, Taxes

1. Mark the expiration date in your calendar – and act at least six months in advance.
2. Send the demand for payment by registered mail with confirmation – from it, you can start counting interest.
3. Do not rely on "interrupting the statute of limitations with a call" – since 2022, a call and mediation only suspend the term for the duration of the proceedings.
4. Consider mediation – a mediated settlement approved by the court has the force of a judicial settlement, and the costs are a fraction of the process.
5. When suing, choose WPS wisely – court fees and the risk of replacement costs increase with the amount; the claim can be expanded after an expert opinion.
6. Demand statutory interest for delay – and specify the starting date (the demand).
7. Make out-of-court settlements in writing with the clause "fully settles claims for inheritance rights."
8. After receiving the money, submit SD-Z2 within 6 months (closest family = zero tax) – transfer, not cash in hand.
9. Paying inheritance rights? Get a receipt/transfer – you can deduct it from the inheritance tax and from PIT when selling property.
10. Cross-border case (deceased/estate abroad)? First, determine the applicable law (EU Regulation 650/2012) – inheritance rights calculated under Polish law may not apply at all.

Frequently Asked Questions

My brother received everything in the will. How much can I demand?

As a rule, half of the value of your statutory share (2/3 if you are a minor/permanently disabled) calculated from the net value of the estate increased by added gifts. See the numerical example above.

My dad transferred the house to my sister 15 years ago and died without assets. Am I entitled to anything?

Yes – gifts to heirs and those entitled to inheritance rights are included without a time limit. You direct the claim to your sister as the donee (she is liable within the limits of her enrichment). The "10 years" applies only to gifts to individuals outside this circle.

I was disinherited in the will. Is that the end?

Not necessarily: disinheritance is effective only for statutory reasons, which must be stated in the will and be true; forgiveness nullifies it. Even effective disinheritance does not take away inheritance rights from your children.

My mom transferred the apartment to my brother under a life estate agreement. Can I include it in my inheritance rights?

No – a life estate is a paid agreement and is not included. However, it is worth investigating whether it was a hidden gift disguised as a life estate (fictitious care) – in that case, the court may assess it differently.

How much time do I have?

5 years from the announcement of the will (in the case of statutory inheritance – from the opening of the estate). According to the prevailing interpretation, the end of the term falls on December 31 of the last year (the rule from art. 118 sentence 2 KC for terms of at least two years). Mediation and a call for a settlement suspend the term during the proceedings.

Can I receive inheritance rights in installments – or defer them if I have to pay them myself?

Yes – it works both ways. The obligated party (heir, donee) can request deferral, installment (up to 5 years, court-ordered up to 10), or exceptionally reduction of inheritance rights (art. 997¹ KC) since 2023. As the entitled party, negotiate a realistic schedule – a hard "everything at once" can be softened by the court.

I live in the USA. How do I claim inheritance rights from my parents in Poland?

Through a legal representative in Poland (lawyer/counsel; you can sign the power of attorney abroad). Deadlines run regardless of your place of residence, and report the received inheritance rights in SD-Z2 (family exemption also applies to those living abroad – Polish/EU citizenship or residence in Poland at the time of acquisition is decisive). Also, check obligations in the country of residence (in the USA: form 3520 for amounts over 100,000 USD).
