Under Hungarian law (Civil Code, Sections 4:99-4:122, Jogtar), parentage is determined by:
(a) The birth mother, who is automatically recognized as a legal parent at birth (Section 4:99).
(b) The biological father, who is presumed to be the legal parent if married to the mother (Section 4:100) or if he acknowledges paternity (Section 4:103). For unmarried couples, the father must formally acknowledge the child or establish paternity through court proceedings (Section 4:110).
In cases of informal sperm donation (e.g., at-home artificial insemination or natural insemination), the donor may be recognized as the legal father if he acknowledges paternity or if a court establishes paternity based on biological evidence or intent to parent (Section 4:110), particularly if he is involved in the child’s life post-birth.
Assisted Reproduction:
In Hungary, assisted reproduction is regulated under Act CLIV of 1997 on Health (1997. évi CLIV. törvény, Jogtar). “Donor-assisted human reproduction” (DAHR) involves donated gametes used in licensed clinics (Section 167). Note: Informal sperm donation outside clinical settings is prohibited and considered illegal under this framework.
DAHR is permitted for married or cohabiting heterosexual couples (Section 167). Single women and same-sex couples are excluded, reflecting conservative policies. Donors must be anonymous—children have no legal right to access donor information (Section 169).
Sperm Donor Agreements:
In regulated DAHR, the donor is not a legal parent if the procedure complies with Act CLIV of 1997 (Section 168). The intending parents are recognized as legal parents at birth (Section 167). Note: Informal sperm donation lacks this protection—donors risk being recognized as legal parents under general paternity laws (Section 4:100 or 4:110), especially if they acknowledge the child or are involved post-birth.
For natural insemination (NI) or informal AI, Hungarian law does not provide specific exclusions for donors. A donor could be deemed the legal father if paternity is established, particularly if the mother is unmarried and the donor acknowledges the child. Courts may intervene based on intent or involvement.
Surrogacy:
Surrogacy is illegal in Hungary under Act CLIV of 1997 (Section 166). Both commercial and altruistic surrogacy are prohibited, and any surrogacy agreement is void. Parentage defaults to the birth mother.
International surrogacy arrangements are not recognized, but intending parents may adopt the child post-birth if they meet adoption criteria (Civil Code, Section 4:139). This process is complex and often requires court proceedings.
Parentage Agreements:
In regulated DAHR, parentage is formalized through consents at fertility clinics, with intending parents recognized at birth registration (Section 167). Informal agreements (e.g., co-parenting or donor contracts outside DAHR) lack legal standing in Hungary. Courts may need to intervene under the Civil Code (Section 4:110) to establish or contest paternity if disputes arise.
Informal arrangements carry significant legal risks, as Hungarian law prioritizes biological parentage over intent in non-regulated settings. A donor could claim paternity, or the mother could seek child support, depending on judicial interpretation.
