Divorce, also known as dissolution of marriage, is the termination of a marriage or marital union, the canceling or reorganizing of the legal duties and responsibilities of marriage, thus dissolving the bonds of matrimony between a married couple under the rule of law of the particular country or state. Divorce laws vary considerably around the world, but in most countries divorce requires the sanction of a court or other authority in a legal process, which may involve issues of alimony (spousal support), child custody, child visitation / access, parenting time, child support, distribution of property, and division of debt. In most countries, monogamy is required by law, so divorce allows each former partner to marry another person; where polygyny is legal but polyandry is not, divorce allows the woman to marry another person.

Divorce should not be confused with annulment, which declares the marriage null and void; with legal separation or de jure separation (a legal process by which a married couple may formalize a de facto separation while remaining legally married) or with de facto separation (a process where the spouses informally stop cohabiting).
