A parent's age has no effect on her/his child support obligation.
You stop paying for child support when your child turns 18.
only if its in the divorce settlement. and if the child is out of school
At 18, you are no longer considered a child for child support purposes unless you have not graduated high school or are disabled. If the child is 18 and out of high school, you must contact the Texas AG to stop child support.
When the child turns 18 and becomes an adult, the parent is no longer obligated to pay child support.
Depends on the state see links below
Yes, you do.
You might, but he would have to ask the courts to enter an order to that effect.
it goes directly to the child.
Up until the child turns age 18 and even if the father was never notified of the existence of the child, as is common.
You can. But also be prepared for that depending on how much time that has passed, you might not get it back.
I heard that once they turn 21 you no longer have to pay child support.unless they make you pay child support as long as they are in school.
It certainly depends on your local laws but usually when the child you are paying support for turns the age of majority, does not live at the home anymore or drops out of school the support payments are to stop. I would check as soon as possible with your local laws as well check your age of majority - you may be intitled to receive some money back.
