My partner and I want to adopt a family members baby but we don't know what or how to handle the birth certificate. Whose name should we list on the birth certificate?

This is something you may want to talk to the birthparents about. Usually the birthparents put whatever name they prefer on the original birth certificate. The name can be changed when the adoption finalizes and a new birth certificate is issued with the adoptive parents listed as the parents and whatever name they choose is listed for the baby.

In general, it is considered a good idea to discuss name preferences with the birthparents. Sometimes everyone likes the same name. Other times birthparents might ask if a middle name can be given to a child to honor them or another family member.

I think this discussion is particularly important in a family adoption, as there may be expectations about naming that are left unsaid and can cause resentment if not openly discussed.
