You have several issues here. Parental rights terminations are handled by the Juvenile Court, and I strongly suggest you contact a qualified attorney to discuss the issues. Failure to pay support is not sufficient grounds to terminate rights, but abandonment can be. Under ARS 8-531: " 'Abandonment' means the failure of a parent to provide reasonable support AND to maintain regular contact with the child, including providing normal supervision. Abandonment includes a judicial finding that a parent has made only minimal efforts to support and communicate with the child. Failure to maintain a normal parental relationship with the child without just cause for a period of six months constitutes prima facie evidence of abandonment." That said, even if parental rights are terminated, the child support obligation will not terminate until/unless the child is adopted. It is also worth noting that ARS 8-114(C) states: "a person shall not be directly or indirectly compensated for giving or obtaining consent to place a child for adoption." This means you cannot offer to waive child support in exchange for the Father's consent. Proceed with caution if you are thinking of entering any type of agreement that includes compensation. Good luck to you and your family.

I agree with my colleague. You also mentioned you have joint custody. I am assuming he has visitation and may be exercising his time. If he has visitation and is exercising his time, then I would find it extremely difficult for you to obtain an adoption without him consenting to a termination of his rights. That said, if he hasn't been around for a long time, then you may have a better shot at terminating his rights. Failure to pay child support is not a sufficient reason to terminate rights, and that obligation would continue even after his rights are terminated, unless the child is in fact adopted. Good luck.
