What Is the Illinois Law on Age & Paying Child Support?

By John Cromwell

In any divorce proceeding, one of the chief concerns is ensuring that children of the marriage are secure. This means that it is important to place them in a home that minimizes the disruption of their lives and to make sure they are financially secure. Child support is a court’s way of financially providing for a child. But child support does not last forever. At some point -- usually based on the age of the child -- support payments end. Illinois, like every other state, has its own laws on paying child support related to the age of the child. When exactly child support payments end will depend on the child’s circumstances.

Standard Child Support Age

The child support order will generally establish when the paying parent’s financial obligation ends, which is normally when the child reaches 18. In Illinois, 18 is the age of majority, when a person is officially considered an adult. In some rare circumstances, a child support order may not define when child support ends. In that case, a paying parent cannot simply terminate the payments when the child reaches 18. He must appeal to the court to have the order modified so the order specifies a date. Failure to continue paying child support until the date is set risks legal penalties for not complying with the support order.


If the child emancipates himself before he turns 18, generally, a parent’s support obligation ends. A child can be emancipated if he gets married, joins the military, gets a job that makes continued parental financial support unnecessary, or the child moves out to establish he wants to be independent. The child is not emancipated if he drops out of school, has a baby, or begins to receive public assistance.

Support After Child Turns 18

A parent may be required to pay support after the child turns 18 for several reasons. If the child is still in high school when he turns 18, the parent may be required to pay support until the child graduates or turns 19. If the original order states that support ends when the child turns 18 but the child is still in high school, the custodial parent may request that support be extended until the child turns 19 or graduates from high school. Child support may also be extended if the child has a mental or physical disability, or the child has entered college or trade school. In the latter case, the paying parent may be required to help pay for room, board, tuition, transportation, registration costs, medical and living expenses.

Multiple Children

If one order covers the support of multiple children, when one child turns 18, the person paying support cannot get away with paying less. Child support orders normally provide one amount the parent must pay for all children -- it is not divided by child. As a result, the paying parent must petition the court to modify the order to a lower amount, once a child comes of age.

California Family Laws on Terminating Child Support

Both parents have a responsibility to provide for the financial needs of their minor children in California. When one parent asks for a child support order, the judge reviews the family's financial information and determines the amount the other parent must pay. The presumed father can terminate his obligation to pay child support by disproving paternity, and either parent can seek a modification based on changed circumstances. If not otherwise terminated, the child support obligation lasts until the child is emancipated.

Does Child Support Go to the Children After They Move Out?

Generally, child support terminates once the child moves out of his parent's home to live independently. Support is meant to benefit the child, but payment is ordered to the custodial parent to cover the noncustodial parent's share of child rearing expenses. State statutes specify conditions that turn a child into an adult, for support purposes. In most states, moving out of the parent's home to live independently qualifies as a transition into adulthood that terminates the support obligation.

Nevada Law on the Emancipation of a Minor Child

The age of majority, or the age at which a child legally becomes an adult, is 18 in Nevada. However, teenagers younger than 18 can petition a Nevada court for emancipation, freeing themselves from their parents' authority. When this occurs, they can enter into legally binding contracts and incur debt, just as adults can. However, in some respects, they’re still minors under Nevada law.
