The Family Law Act (R.S.O. 1990, c. F.3) is a statute passed by the Legislative Assembly of Ontario in 1990, regulating the rights of spouses and dependants in regard to property, support, inheritance, prenuptial agreements, separation agreements, and other matters of family law. In 1999, this statute was the subject of a watershed ruling in M. v. H. by the Supreme Court of Canada that established the equality of spousal rights for same-sex couples under Canadian law.
