The
immediate family is a defined group of relations, used in rules or laws to determine which members of a person's
family are affected by those rules. It normally includes a person's parents, spouses, siblings, children and first cousins. It can contain others connected by birth, adoption, marriage, civil partnership, or cohabitation, such as grandparents, grandchildren, siblings-in-law, half-siblings, adopted children and step-parents/step-children, and cohabiting partners.
