Good to know

On a motion filed before the child reaches majority, a court must continue support to age 22 for a child with a developmental disability who is a full-time secondary school student.

Acts 2024, No. 448 (effective Jan. 1, 2025) amended this section and repealed its former Subsection E.

What this means in practice

Support does not always stop on its own. Depending on the state and the order, the paying parent may need to ask the court or the child support agency to end or adjust the order, and past-due support remains owed after the end date.

When there is more than one child on an order, the amount may not drop automatically when the oldest child reaches the end age. Reviewing how the order is written, and whether it lists a separate amount per child, helps show what happens next.

Parents can often agree in a divorce or separation agreement to pay for things the law does not require, such as college costs. A written agreement approved by the court can be enforced like an order, so its wording matters and a local family law attorney can review it.
