Last month, the Commonwealth's highest appellate court considered how legal parenthood is defined in the context of children born to a same-sex couple as a result of artificial insemination. The case, Partanen v. Gallagher, is currently under advisement by the Supreme Judicial Court. The Court's opinion could result in new parameters for what it means to be a parent in Massachusetts. At issue is the scope of the legal rights that an unmarried woman, who was previously in a relationship with the child's biological mother when the child was conceived using artificial insemination, enjoys after the relationship ends.
