The child has no legal recourse. The mother should be the one to sue because she has been responsible financially for the child all of those years. The laws may be different in your state, but I doubt you will get far. Consult a lawyer.
yes
no
impossible Since the purpose of child support is to support a child, it cannot be waived by the child's mother. The child has to be supported, whatever opinion the mother may have about it. So no, that would not be a valid agreement. If a man fathers a child, he is liable for child support.
No. The statute of limitations for child support arrears in New York is twenty years from the date of the default. However, in your case it seems that your mother never obtained a court order for child support. You have no cause of action.
No.
No, not likely. If you are over 18 yrs. of age, you are considered an adult, and child support is exactly what it is...."child-support" for CHILDREN, not adults!
The order goes to child support enforcement to persecute.
No, that option is only available to children whose mother never filed for child support on a father whose never lived in the home.
Your mother should have pursued your father in court for child support when you were young. In most jurisdictions you have no legal standing to sue your father for child support now, and especially if there was no original child support order. If there was an order at some time your mother may be able to sue for arrears but that seems not to be the case.
Your child payments will never go down, the cost of a child will only go up.
Child support has nothing to do with the child's name. Just because you pay support, the mother is not obligated to give the child your last name. Many people feel that the child will be more comfortable having the same last name as the custodial parent.
Only after reaching the age of majority, provided the mother has never filed or received any. This only involves contacting child support enforcement.
