Child support is a legally mandated payment made by the non-custodial parent to the custodial parent or guardian to contribute to a child's upbringing after divorce or separation. It is intended to help cover the child’s basic needs, such as food, housing, education, healthcare, and other necessary expenses. The amount of child support is usually determined by state guidelines, taking into account factors like each parent's income, the child's needs, the number of children involved, and the amount of time the child spends with each parent.

Child support can be adjusted over time based on changes in either parent's financial circumstances or the needs of the child. In cases where the non-custodial parent fails to pay support, enforcement measures may be taken, including wage garnishment or legal action. Ultimately, the goal of child support is to ensure that children receive consistent and adequate financial support from both parents, regardless of their living arrangements.
