Every adoption of this type will be different, based on the type of relationship that the birth parents and the adoptive parents have agreed to. Both identifying and non-identifying information about the adoptive parents and the birth parents is shared with each other, which can include last names, addresses, and telephone numbers. In some open adoptions, the birth parent and the adoptive family know each other and have ongoing communication about the child. If the parents on both sides agree, the adoptive parents may even be allowed to be present for the delivery of the child, thus allowing them to vicariously share in the birthing process. Neither the birth parents nor the adoptive parents are forced to participate in an open adoption if that is not what they are comfortable with. Although there is some disagreement on the subject, it is suggested that the child, and thus the adoptive parents that will be raising the child, are the primary beneficiaries of some of the most significant benefits that can result from an open adoption.
