In family law and government policy, child support or child maintenance is the ongoing obligation for a periodic payment made directly or indirectly by a non-custodial parent to a custodial parent, caregiver or guardian, or the government, for the care and support of children of a relationship or marriage that has been terminated. In family law, child support is often arranged as part of a divorce, marital separation, dissolution, annulment, determination of parentage or dissolution of a civil union and may supplement alimony (spousal support) arrangements.

The right to child support and the responsibilities of parents to provide such support have been internationally recognized. The 1992 United Nations Convention on the Rights of the Child, a binding convention signed by every member nation of the United Nations and formally ratified by all but two, declares that the upbringing and development of children and a standard of living adequate for the children's development is a common responsibility of both parents and a fundamental human right for children, and asserts that the primary responsibility to provide such for the children rests with their parents.   Other United Nations documents and decisions related to child support enforcement include the 1956 United Nations Convention on the Recovery Abroad of Maintenance, which was ratified by the vast majority of UN member nations.
