Alimony, also called aliment (Scotland), maintenance (England, Ireland, Northern Ireland, Wales, Canada, New Zealand), spousal support (U.S., Canada) and spouse maintenance (Australia), is a legal obligation on a person to provide financial support to their spouse before or after marital separation or divorce. The obligation arises from the divorce law or family law of each country. In most jurisdictions, it is distinct from child support, where, after divorce, one parent is required to contribute to the support of their children by paying money to the child's other parent or guardian.
The term alimony comes from the Latin word alimonia ("nourishment, sustenance", from alere, "to nourish"), from which the terms alimentary (of, or relating to food, nutrition, or digestion), and aliment (a Scots Law rule regarding sustenance to assure the wife's lodging, food, clothing, and other necessities after divorce) are also derived.
The Code of Hammurabi (1754 BC) declares that a man must provide sustenance to a woman who has borne him children so that she can raise them:
137. If a man wish to separate from a woman who has borne him children, or from his wife who has borne him children: then he shall give that wife her dowry, and a part of the usufruct of field, garden, and property, so that she can rear her children. When she has brought up her children, a portion of all that is given to the children, equal as that of one son, shall be given to her. She may then marry the man of her heart.
The above law only applies to women who had children with her husband. This fits more closely with the definition of child support in some jurisdictions.
Alimony is also discussed in the Code of Justinian.
The modern concept of alimony is derived from English ecclesiastical courts that awarded alimony in cases of separation and divorce. Alimony pendente lite was given until the divorce decree, based on the husband's duty to support the wife during a marriage that still continued.
