Find out when your individual state truly emancipates minors (in Alabama it's 19).
Do you pay through the state's CS office?
Contact the school prior to graduation and see if they will send you proof that the child has graduated -- if your states says "emancipated after high school" -- like make sure all the stars line up.
Then file with the court and ask that the child be emancipated......and if you pay through the state CS -- send them
certified letter asking the same with proof.
About 30 days prior to the final date.....give them some time to work it out.
Some situations t isn't necessary -- other states it is -- other states continue on with age of majority support (college).
