What rights do birth grandparents have in their child’s decision to place a child for adoption?

In Arizona, grandparents have no legal rights regarding their child’s voluntary decision to place a child for adoption. If the grandparents want to adopt the baby, the birth parents (whether minor or adult) must agree. The mother is required only to notify the father of the baby if she is planning an adoption. If ICWA applies, the Indian Nation must also be notified, by the person/agency facilitating the adoption, and birth grandparents do have rights under the placement preference guidelines.
