Family allowance is a legacy term used in UK and Irish legal practice to describe the state cash payment for children now known as Child Benefit. In England and Wales, Scotland and Northern Ireland, “family allowance” referred to payments under the Family Allowances Acts (notably the Family Allowances Act 1945), which were replaced by Child Benefit under the Child Benefit Act 1975 (implemented from 1977). In Ireland, the equivalent payment is Child Benefit under the Social Welfare Consolidation Act 2005; earlier legislation used “children’s allowances” (Children’s Allowances Act 1944).The phrase is not a current term of art. It commonly appears in older statutes, case law, maintenance orders, trust deeds, settlements, leases and employment documents. In modern statutory interpretation and contractual construction, a reference to “family allowance” will ordinarily be read as Child Benefit (or the Irish equivalent) unless the context shows a distinct contractual or discretionary allowance.Practical significance includes identifying the payee for Child Benefit when assessing financial provision, child maintenance, residence of a child, or related immigration and tax interactions. Usage is broadly consistent across the UK and Ireland, though the governing legislation and terminology differ as noted.
