When does my child support obligation end?

Child support ends typically when your child reaches the age of 18.  However, if your child goes to school full time after high school, then your child may not be emancipated until they finish their studies.  Of course this does not mean that your child goes to school forever and remain dependent upon you. Typically, there is a cap of 23 years old, assuming your child has been attending school full time. So you're typically not on the hook for child support if your child goes to some sort of graduate program.  If your child takes a semester off they may be temporarily emancipated, but your child support obligation can resume if they return to school on a full time basis.  There are additional instances which may emancipate your child such as if they join the military or get married.
