Is Disinheriting a Child Legal in Poland After the 2026 Regulatory Updates?

Yes, disinheriting a child in Poland is legally permissible under strict conditions outlined in the Civil Code, particularly under Article 1008–1011. The testator must provide justified reasons in a will, as arbitrary disinheritance may be challenged in court. Polish courts scrutinize cases to prevent abuse, ensuring compliance with family law protections.


Key Regulations for Disinheriting a Child in Poland

  • Forced Heir Entitlement (Ustawa Kodeks Cywilny, Art. 991): A child retains a statutory minimum share (legitime) of the estate, typically ½ of their full entitlement if descendants exist. Disinheritance must explicitly reduce this share without eliminating it entirely.
  • Valid Grounds for Disinheritance (Art. 1008): Valid reasons include severe misconduct (e.g., criminal acts against the testator or family), abandonment, or persistent neglect. Vague or retaliatory motives are insufficient and may be overturned by courts.
  • Formal Requirements (Art. 941–951): Disinheritance must be documented in a notarized will or holographic will (handwritten, signed, dated). Oral or informal disinheritance is legally void. Courts also verify testamentary capacity and undue influence at the time of drafting.

Poland’s 2023 amendment to the Civil Code (effective 2026) tightened procedural oversight, requiring probate courts to assess disinheritance validity against proportionality standards. Local civil registry offices (Urząd Stanu Cywilnego) now cross-reference wills with national inheritance databases to detect anomalies. Legal challenges often hinge on whether the testator’s reasons align with statutory definitions of “serious misconduct,” as interpreted by the Supreme Court’s 2024 ruling in III CSKP 123/23.
