When Does Child Support End in California?

Child support is an essential aspect of family law, designed to ensure that children receive financial support from both parents, even in cases of divorce or separation. In California, as in most states, child support typically ends when the child reaches the age of 18. However, there are situations where child support can end earlier or later than that milestone age.

Standard Termination at Age 18

In California, the general rule is that child support terminates when the child turns 18. When a child reaches this age, they are legally considered an adult, and they are expected to be self-sufficient. Therefore, the parent paying child support is no longer obligated to make these payments.

However, it's essential to note that if the child is still attending high school and has not graduated by their 18th birthday, child support will continue until they finish high school or reach the age of 19, whichever comes first. This extension aims to ensure that children receive support until they complete their basic education.

Child Support Ending Early

Child support may end earlier than the standard age of 18 in certain situations. Here are some scenarios where this can happen:


If a child becomes legally emancipated, child support obligations can end. Emancipation occurs when a minor child becomes financially self-supporting or marries before turning 18. In such cases, the child is considered legally independent, and the parents are no longer required to provide financial support.

Active Military Service

If a child joins the military before turning 18, child support may end. Military service is generally seen as an emancipating event, as the child is now financially supported by the armed forces. However, it's crucial to consult with a family law attorney in these cases to ensure compliance with specific regulations.


In California, if a child gets married before reaching the age of 18, child support can end. Marriage is considered another form of emancipation, as the child is presumed to have taken on adult responsibilities.

Entry into a Coherent Living Situation

If a child leaves their parents' home and establishes a coherent living arrangement, child support may cease. This could include situations where the child moves in with a relative or guardian, enrolls in a college, or obtains gainful employment while still a minor.

Paternity Disestablishment

In some cases, if there is a dispute over paternity, child support may be terminated if it's proven that the alleged father is not the biological parent. This typically requires legal action, including DNA testing and court orders.

Child Support Extending Beyond Age 18

While child support generally ends when a child turns 18 or graduates from high school, there are circumstances where it can extend beyond this age:

College Expenses

In some cases, parents may agree or the court may order that child support continue to cover college expenses, including tuition, books, and living costs. This typically requires specific language in the divorce or separation agreement or a court order outlining the continuation of financial support during higher education.

Disabled or Special Needs Children

If a child has a severe disability or special needs, child support may continue beyond the age of 18. The court will assess the child's unique circumstances to determine the appropriate level of support, which may include medical expenses and ongoing care.

Agreements Between Parents

Parents can agree to continue child support beyond the age of 18 if they believe it's in the best interest of the child. These agreements should be documented and presented to the court for approval to ensure legal enforceability.

Understanding the child support end date in California is essential for parents who are going through a divorce or separation. By knowing the basics of child support, when it ends, and how to modify orders, parents can better manage their finances and co-parenting relationship.
