Child Support in California
State-specific overview · Family Law
California uses income shares model; support ends at age 18 or high school graduation, whichever is later.
How California treats Child Support
California applies the income shares model under Family Code Section 4050 et seq., calculating support based on each parent's net disposable income and the percentage of time each parent has custody. The guideline formula considers both parents' income, tax filing status, and mandatory deductions. Support terminates when the child reaches 18 years old or completes high school, whichever occurs later. California courts retain discretion to order support beyond these ages if the child has special needs or is pursuing higher education.
The general definition of Child Support
Court-ordered payments from one parent to the other for a child's living expenses.
Child support is money that a court requires one parent to pay to the other parent (or guardian) to help cover the child's expenses like food, housing, education, and healthcare. The amount is usually calculated using state guidelines that consider both parents' incomes, the number of children, and custody arrangements. Child support continues until the child reaches the age of majority, typically 18 or 21 depending on the state. It's a legal obligation separate from custody decisions.
