As of 2011 they changed the formula. I do not remember exactly how it works but you can find it here http://www.a1childsupportinfo.com
If your child is married they are emancipated so there should be no need for child support. Contact the court.
Yes, but it affects the amount.
The State in which the child resides.
The mother files in Florida and child support enforcement handles it from there.
Yes, for past-due support.
Best to go through the FL child support agency or FL district attorney - the State has an interest in this matter.
If they are not in college. see link
If no support is in arrears, you file for termination of child support with the agency of jurisdiction over the support case (where the order originated). It will be up to the court to determine whether or not your child support will end if they are legally residing in a state allowing for earlier termination.
at the present the state of florida emancipation is 18.
If you "honestly" report your tips, it can be added to your yearly income and sooner or later child support is boing to want their cut. For more information check out http://www.a1childsupportinfo.com
Check your state web site.
File an appeal (request for hearing) with the FL child support agency (this must be done fairly quickly after the notice of intent to suspend license). If you are not satisfied with their decision on your appeal, sue them in the FL courts.
