I agree w/ marty..call an atty. From my understanding though, child support a tough one. States like to see it paid regardless of the age of the child. My niece is 19 and her father owes around $22,000 back-child support pay...and the states ( CO & IL ) are still attempting to collect payment!
I believe if the mother received state help financially (some form of aid like food stamps or housing, etc) the state will continue to collect back-child support from the parent owing it!!! States feel that if fathers (or mothers) who don't pay their child support, force the other parent to need state aid..they will go after the child-support owing parent! That is the current situation w/ my sis & niece!
Contact your local child support office and ask for legal assistance to your questions.
BTW...most, if not all, state offices ( in all states) offer spanish-speaking reps and atty's.( or at least translators)
Best of Luck!
