In Kentucky, a child support order ends when a child turns eighteen, unless the child is still enrolled in high school, in which case, child support will continue until the end of the school year in which the child turns 19.
In certain circumstances, such as when an adult child is disabled, child support may continue past the age of 18 (or 19 and still in high school).
If the support obligation is for more than one child, the obligation will not automatically terminate when one child reaches the requisite age. In these situations, the parent with the child support obligation must request a modification of his or her obligation.
There are many potential exceptions to the rules provided above and it is always important to discuss the facts specific to your case with a family law attorney.
