kinship adoption
A kinship or relative adoption is one in which the adoptive parents are relatives who are biologically related to the child to be adopted, such as a grandparent, aunt, or cousin. In kinship adoption, as opposed to kinship care, the relatives legally adopt the child.

kinship care
A relative placement or kinship care occurs when a child is placed in the care of birthfamily members, members of their tribes or clans, godparents, stepparents, or other adults who have a kinship bond with the child. This may be an informal agreement among the parties, a formal foster care placement made with the assistance of a public agency, or a pre-adoptive placement. The relatives may be awarded custody or legal guardianship by the court. When an agency is involved in a formal foster care placement, the relative may be entitled to the same benefits and supports as other foster care parents.
