This depends on what it is you're asking. Does you state require support beyond high school? If it does, than make a request to child support enforcement to split the payment so that part if it can go to her, directly. See link for laws on child support beyond high school.
If child support does not extend beyond high school, you will need to do a modification. see related question.
Generally, the obligation ends when the child reaches 18 years of age unless the child is still in high school - in which case the support ends upon the child's graduation from high school, or the child's 19th birthday, whichever occurs first.
Nope.
no if she is 18 and not in collage.z
File for stop emotion
A person may have to pay child support even if the child is 18 and in college and has a medical condition. This may be true if the person owes back child support.
The depends on whether child support in your state stops at that time. Only a few states do. see links below
No support
18 is not the age for stopping child support in all states. If it is 18 in your state, by the time you get a court hearing the child will have aged out. see links below
Not by state law, however it can be addressed in the order. see link below
Probably not, but it depends on the laws in your area and what the support agreement actually says. Contact a lawyer to find out.
