Following the United States Supreme Court’s decision in Obergefell v. Hodges, 576 U.S. 644 (2015), there is no real difference in the divorce process for same-sex couples and opposite-sex couples. But same-sex couples may encounter some additional complications in the divorce process regarding issues such as child custody if, for example, one of the same-sex spouses was the biological mother and the biological father did not agree in writing to terminate his parental rights, and later seeks custody of the child.

In Washington state, following the Supreme Court's decision in Obergefell v. Hodges, same-sex couples have the same rights and processes for divorce as opposite-sex couples. This means that the legal procedures for dissolving a marriage, dividing property, and determining alimony are the same. However, same-sex couples may face additional challenges, particularly concerning child custody. If a child was born to one spouse during the marriage, and the other spouse is not a biological parent, the non-biological parent may need to take legal steps to establish parental rights, such as adoption. If the biological father of the child did not relinquish his parental rights and later seeks custody, this could complicate the situation. In such cases, the court will consider the best interests of the child, which may include factors like the child's relationship with the non-biological parent, the stability they provide, and the intention of both spouses during the marriage to raise the child together.
