A more thorough explanation: In legal terms, a “natural relative” refers to a person who is related to another person by blood, as opposed to a relative by marriage or adoption. This term is often used in legal documents to distinguish between relatives who are connected by biological ties and those who are related through other means.
Example: The natural relative of a child is typically their parent or guardian.
