Child support obligations generally end when the child reaches the age of majority as defined by state law (usually 18-21) or graduates from high school. If a child joins the military or gets married before reaching the age of majority, or successfully petitions the court for emancipation (“to remove the disabilities of minority”), the child will be emancipated and child support obligations will usually be terminated. But the child support obligation in this circumstance does not terminate automatically, and the parent generally must seek an order terminating the support obligation from the court that issued the child support order. And if the child has special needs (health care, living, education) or has not graduated from high school by the age of majority, the parent may be required to pay child support even after the child reaches the age of majority or is emancipated.

In Kentucky, child support obligations typically end when a child reaches the age of majority, which is 18 years old, or graduates from high school, whichever is later. However, if a child under the age of majority gets married, joins the military, or is legally emancipated, the child is considered to be self-supporting, and the parent's obligation to pay child support may be terminated. It is important to note that the termination of child support under these circumstances is not automatic. The parent must file a motion with the court that issued the original child support order to have the obligation terminated. Additionally, if the child has special needs or has not graduated from high school by the age of 18, the parent may be required to continue support. In cases where the child has special needs, support may extend indefinitely, depending on the child's needs and the court's determination.
