Can the mother change her mind after signing the legal consents to the adoption?

No, the mother cannot change her mind about the adoption AFTER she has signed the legal consent forms (relinquishment). In Arizona, once the consents are signed they are irrevocable (cannot be changed). The only exception would be if she could prove in a court of law that she 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.
