This document is typically used when the mother and father are not married, and the father wants to establish his legal rights to the child. There are two types of Arizona Voluntary Acknowledgment of Paternity Instructions. The first is the Arizona Voluntary Acknowledgment of Paternity Form. This form must be signed and notarized by both the mother and the father and is used to establish legal paternity of the child. The second type of instruction is the Arizona Voluntary Acknowledgment of Paternity Affidavit. This document is used to establish paternity without a court order and must also be signed and notarized by both the mother and the father.
