nonrelative
Not family member
A nonrelative is someone who is not a family member.
The term appears most often in legal, medical, and social science contexts where the distinction matters: The child was placed with a nonrelative foster family.
As an adjective, it describes things unrelated to kinship: nonrelative caregivers, nonrelative household members.
