Yes, unless/until the child is adopted.
Yes. You are obligated to pay child support in AZ even if your parental rights are severed.
by "signing over rights" I persume you mean, terminating her parental rights and no, she is not obligated to pay child support, however, any accumulated back child support, or "arrears" is required to be paid, unless agreed otherwise. For this you would have had a prior order to pay support prior to the terminating of the mother's rights. When your rights to a child is terminated it is as if the child was never yours and your rights to the child, and obligation for the child are forever terminated.
Who legally adopted the child?If the mother's new husband legally adopted the child, then the biological father's parental rights had to be terminated first. Which means that the biological father is NOT obligated to pay child support anymore. The new adoptive father has taken on all rights and responsibilities for the child.
if the mother terminates her rights can he collect child support from the mother if child lives with him?
No, but you will be obligated to pay child support without any rights. see links below
An unmarried father cannot "choose" to not pay child support. The laws in every state require that a father pay for the support of his child. The mother must bring an action to the appropriate court so that a child support order can be established. Visitation rights are separate and a father can have visitation rights established by the court. Visitation rights are not dependent on paying child support.
If you mean, the child's mother (ex-wife) has custody, the child's father (ex-husband) is obligated or potentially obligated for support.
The parent either mother or father is obligated to pay child support until that child/children turn 18 years old.
If you're in the US, yes, he's still obligated to pay his regular child support.
It is in the best interest of your child for you to pay child support. If the child is still living in Mexico and the mother has a court order, you need to pay support. If there is no court order, you are not legally obligated to pay support.
The father of the child (whether he was ever legally married to the child's mother or not) is obligated to pay the child support. His new spouse cannot be LEGALLY obligated to pay it since she has no part in the action at all, but there is no bar to her helping her husband pay it if she wishes to do so.
Yes, until/unless the child is adopted.
