term:

Family

family n

pl: -lies
1 : a group of individuals related by blood, marriage, or adoption
2 : a group of usually related individuals who live together under common household authority and esp. who have reciprocal duties to each other NOTE: The interpretation of the word family in a law context depends upon the area of the law concerned (as contract or zoning law), the purpose of the document (as a statute or contract) in which it is used, and the facts of the case. Often for zoning purposes, the occupants of a group home are considered a family if the organization is like that of a family or if the home is going to be a permanent rather than a transitional residence for the occupants.
