Arizona Voluntary Acknowledgment of Paternity (VAMP) is a legal document that is used to establish a legal relationship between a father and a child. VAMP establishes the father's legal rights and responsibilities towards the child such as the responsibility to provide financial and emotional support. VAMP also serves to establish the child's right to inherit from the father and the child's right to receive Social Security, Veteran's, and other benefits from the father. There are two types of Arizona Voluntary Acknowledgment of Paternity: an in-hospital VAMP and an out-of-hospital VAMP. An in-hospital VAMP is completed at the hospital after the birth of the child and can be signed by both parents with the assistance of hospital staff. An out-of-hospital VAMP is completed outside the hospital and requires the father's signature and the signature of a witness. It must then be filed with the Arizona Department of Health Services.
