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

A parent transferred a house to one of the children, while the will excludes the rest of the family? The law does not leave you empty-handed: inheritance rights guarantee a minimum share in the estate of close relatives as stipulated 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 regulations: 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 and taxes look like – plus 30 proven tips at the end.

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

In Brief

Inheritance Rights – Initial Assessment in a Few Steps

The diagram is a simplified guide based on this manual – in specific cases, especially with large amounts, it is advisable to consult a lawyer.

Step 1: Check if you have the right to inheritance rights

• Only descendants, the spouse, and parents of the deceased are entitled – and only if they would be entitled to inherit under the law in the 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.
• Those who do not have inheritance rights: siblings, extended family, unmarried partners, spouses after divorce (and in declared separation), as well as those who have renounced the inheritance, waived their inheritance rights through a notarial agreement, been declared unworthy, or effectively disinherited.
• You are entitled to inheritance rights if you have not received the due value in any form: gifts from the deceased, inheritance, legacy, 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 – with numbers

1. Determine the "calculatory" statutory share

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

2. Apply the inheritance fraction

   × 1/2 (principle) or × 2/3 if you were a minor or permanently unable to work 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 + legacies, 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 legacies and instructions are not deducted.

4. Properly add gifts

   Do not add: 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 added (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 legacies for your benefit are counted 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 your 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 with a right to reclaim

   If you cannot obtain the amount due from the heirs – those who received specific assets through a legacy are liable: jointly, within the limits of their enrichment, with the possibility of releasing themselves by returning the legacy item (art. 999¹ KC). The family foundation is also included in the chain if the deceased contributed assets to it.

3. Finally, donors – from the last gift

   A donor is only liable within the limits of enrichment from the gift added to the estate, and a previous donor – only when it is impossible to obtain supplementation from the later donor (art. 1000–1001). They can release 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 cases end in a settlement – judicial, notarial, or mediated.
• Be aware of the statute of limitations during negotiations: since June 30, 2022, a request for mediation only suspends the statute of limitations for the duration of the proceedings (art. 121 points 5–6 KC) – it does not interrupt it and does not provide "new 5 years". Many online tips about "interrupting the statute with a request" are outdated.
• Lawsuit: you file the case against the obligated parties before the court of the last ordinary residence of the deceased – this is the exclusive jurisdiction (art. 39 KPC), you have no choice of another court. District court for disputes up to 100,000 PLN, regional court 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 someone demonstrating legal interest), land and mortgage registers, estate documents; the value of real estate in dispute is determined by a court expert (a private valuation is a good starting point for negotiations).
• Interest: demand statutory interest for delay from the demand/lawsuit – in a multi-year process, these are significant amounts.

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 the principles of social coexistence against the will of the testator; crimes against life, health, freedom, or gross insult to the testator/closest 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 – disinheritance of a son does not deprive grandchildren of their inheritance rights!
• Unworthiness to inherit (art. 928): determined by the court at the request of a person with 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 their inheritance rights. Since November 15, 2023, the reasons have been expanded to include persistent evasion of specified alimony by court ruling/agreement/contract and the obligation to care for the testator.
• Installments, deferral, reduction (art. 997¹ KC, since May 22, 2023): any obligated party can request deferral of the payment deadline or installment payments (up to 5 years; the court may extend this to 10 in exceptional cases), and in exceptional cases – reduction, taking into account the situation of both parties. If the circumstances for reduction cease, the entitled party may demand the return of 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 testator for years) – case law applies this cautiously.
• Life estate instead of a gift: property transferred under a life estate agreement (paid) is not added to the base – this is lawful planning, which we discuss in the guide on gifts and life estates.
• Waiver (art. 1048): through a notarial agreement with the testator, 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 Tax

• The received inheritance rights are subject to inheritance and gift tax (art. 1 sec. 1 point 5 of the inheritance tax act); the obligation arises at the moment of satisfaction of the claim (receipt of money/items).
• The closest family pays zero – provided they file 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 estate of the heir (art. 7 sec. 3 of the inheritance tax act), and when selling inherited property, it is an expense in PIT (art. 22 sec. 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 from the last decades – including 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 an estate with debts, consider accepting it with the benefit of inventory instead of renouncing, if you are counting on inheritance from the donees – consult the order of actions.
7. Gather evidence of your relationship with the deceased (care, contacts) – these will be useful in the event 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 among the "disinherited" – and whether the reason in the will is true and specific.
10. If you are a minor or permanently unable to work, your share is 2/3, not 1/2.

Calculating and Gifts

1. Value real estate 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. Add legacies as you would 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 added – but check if 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 a beneficiary and funds from OFE/ZUS sub-accounts do not enter the estate – do not include them in the base.
8. Document values on the day of determining inheritance rights – update old valuations before the hearing.
9. With multiple donees, remember the order: demand first from the last one.
10. A 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 deadline for the statute of limitations 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 with a demand" – since 2022, a demand and mediation only suspend the statute for the duration of the proceedings.
4. Consider mediation – a mediated settlement approved by the court has the power of a judicial settlement, and costs are a fraction of the process.
5. When suing, choose the 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 (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) – bank 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 the 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 got everything in the will. How much can I claim?

As a rule, half of the value of your statutory share (2/3 if you are a minor/permanently unable to work) 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 any assets. Am I entitled to anything?

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

My mother transferred an apartment to my brother under a life estate agreement. Can I add it to my inheritance rights?

No – a life estate is a paid agreement and is not added. However, it is worth examining 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 deadline falls on December 31 of the last year (the rule from art. 118 sentence 2 KC for deadlines of at least two years). Mediation and a request for a settlement suspend the statute for the duration of 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 payments (up to 5 years, judicially 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 can I claim inheritance rights from my parents in Poland?

Through a legal representative in Poland (lawyer/legal advisor; you can sign the power of attorney abroad). Deadlines run regardless of your place of residence, and the inheritance you receive should be reported 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 your country of residence (in the USA: form 3520 for amounts over 100,000 USD).
