Child custody is the legal term used to describe the legal and physical relationship between a parent and child; it comes into question in proceedings involving dissolution of marriage, annulment and other legal proceedings where the residence and care of children are concerned. In most jurisdictions child custody is determined by the best interests of the child standard.
