Family law · child maintenance
Both parents have a legal duty to maintain their child according to their means, whether or not they were ever married to each other. If a parent does not provide adequate financial support, the other parent (or guardian) can apply to court for a maintenance order. The Family Law (Maintenance of Spouses and Children) Act 1976 is the main law, and the position of children whose parents were not married is protected by the Status of Children Act 1987 and the Children and Family Relationships Act 2015.
Yes. The duty to maintain a child does not depend on the parents having been married. A child's right to support is protected regardless of the parents' marital status.
There is no fixed formula. The court looks at the child's needs and each parent's income, assets, and reasonable outgoings, and sets an amount it considers fair in the circumstances.
You can apply to enforce a maintenance order, including through an attachment of earnings order that deducts maintenance directly from the paying parent's wages.
