You don't. The mother's statement(s), even if false, does not relieve you of this obligation.
No but your mother can. The child support goes to her and not you.
It depends on the state. In most states the father would still be required to pay child support, even though he is living with the mother and the child. However, if the father was financially supporting the mother and child, it's likely that the courts would suspend the child support order.
Lawyer up. It's your only chance.
This depends on a couple of things, the state you are in and what your court order says. If the child is living full time with one parent it is the other parent who pays child support. However, if the child is living with the father for the summer (summer possession) the father will still continue to pay the mother child support even though the child temporarily is living with the father. The reason for this is the mother still has bills that are keeping the house and such for the child to come back too. The only way a father will not have to pay is if the court order says that during summer possession the father does not have to pay child support, but normally in this case the mother would not be obligated to pay child support to the father. However in the end, people should do what is best for the children and not worry about the dollars they receive or don't receive.
Child support for the grandchild is the responsibility of the grandchilds father, not the grandchild. If the father is a minor, you can take his parents to court for support.
Yes. Pay up.
yes
Yes child support is paid even when parents don't live together.
The mother should contact her (US) state child support agency. Be patient but persistent. Good luck!
Yes, a mother South Africa can get an arrest warrant for a father living in another country if he stops paying for child support.
If the grandparents are legal guardians and the child is living with them, the both of you as the biological parents have to pay child support to the grandparents.
Depends on the circumstances. Please consider the situation. The biological father is living with the mother and child/children, therefore he is (or should be) aiding in the support of the household. If the father is not living with the mother and child the mother can and should file for support regardless of the status of her current relationship with the biological father. If you are referrring to state aid regarding the care of a minor child/children, the court will NOT allow such action when the biological father is present. Of course the family may qualify for other public assistance benefits based upon their current economic circumstances.
