My mother's brother died in Iowa, we live in Nevada. The Lawyer sent us a form to sign before they send the check. The Form is a, ''Receipt And Waiver Of Notice''. She is suppose to sign it and send it back before she gets the check. The wording of the Form sounds like she already received it and is giving up any intrest in anything else if found. The fitst sentence says, ''The undersigned has received from the fiduciaries in the above entitled matter, all money and property to which entitled.'' Is this normal? If she signs this can they keep her inheritence?
