Same-Sex Marriage and Relationships under Family Law
Same-Sex Marriage and Relationships under Family Law
1. Introduction
Family law traditionally governs relationships such as marriage, divorce, child custody, and adoption. Historically, most jurisdictions defined marriage as a union between a man and a woman. Over recent decades, many countries and courts have expanded the recognition of same-sex relationships and marriage, significantly changing family law.
The recognition of same-sex marriage and relationships impacts issues like:
Legal status of partners
Rights to marry
Adoption and parenting
Inheritance and spousal benefits
Anti-discrimination protections
2. Legal Evolution of Same-Sex Marriage
Early recognition came through:
Civil unions or domestic partnerships.
Court rulings declaring bans on same-sex marriage unconstitutional.
Legislative acts legalizing same-sex marriage.
