# Queensland surrogacy legal ruling for twins > Live situation record from CLSTR: https://clstr.news/situations/queensland-surrogacy-legal-ruling-for-twins > Updated: 2026-08-31T15:44:59.000Z. Sources: 27. Developments: 3. In Queensland, Australia, a legal case emerged regarding twins born in November 2025 who have different biological parents due to a rare medical phenomenon known as heteropaternal superfecundation. The surrogate mother, identified in court documents as DZ, underwent an IVF embryo transfer for an altruistic surrogacy agreement while simultaneously becoming pregnant naturally with her own partner. DNA testing confirmed that the girl is the biological child of the intended parents, while the boy is the biological child of the surrogate and her husband. Because state surrogacy laws generally prohibit the separation of “birth siblings” born from the same pregnancy, the matter required intervention from the Children’s Court of Queensland. Judge Jodie Wooldridge ruled that the infants should be classified as “gestational twins” rather than “birth siblings” under the specific legal definitions of the Surrogacy Act. This distinction allowed the two separate families to legally claim parentage and raise the children independently. Both families have expressed a desire for the children to maintain a relationship as they grow up. ## Claims - A woman in Queensland agreed to be a surrogate for a couple unable to conceive naturally.
