The Civil Partnership Act is a law that allows same-sex couples to legally register their relationship in a manner similar to marriage. Introduced in the United Kingdom in 2004, it provides couples with legal recognition and rights, including matters related to inheritance, tax, and next-of-kin status. The Act was a significant step towards equality for the LGBTQ+ community, enabling couples to enjoy similar legal protections as heterosexual married couples. Over time, many provisions of the Act have been integrated into broader marriage laws, reflecting changing societal attitudes towards relationships and family structures.
