Can the father change his mind after signing the legal consents to the adoption?

No, the father cannot change his mind about the adoption AFTER he has signed the consents (legal documents). In Arizona, once the consents are signed they are irrevocable (cannot be changed). The only exception would be if he could prove in a court of law that he signed under fraud, duress or undue influence. Having no funds to provide for the child or being in a bad living situation is not considered duress.
