Marriage legislation refers to the laws and regulations that govern the institution of marriage. These laws outline the requirements for entering into a marriage, such as age, consent, and legal capacity. They also address issues like marriage licenses, ceremonies, and the rights and responsibilities of married individuals. In many countries, marriage legislation has evolved to include provisions for different types of unions, including same-sex marriages. This reflects changing societal values and aims to ensure equality and protection for all individuals, regardless of their sexual orientation. Key legal concepts often addressed include divorce, property rights, and child custody.
