In legal definitions for interpersonal status, a single person is someone who has never been married. A person who was previously married and was divorced or widowed is usually considered an "unmarried" person. If a marriage is annulled, however, or it is found to have been void ab initio (i.e. not valid in law to start with), and assuming the person was not married previously, that individual is single, rather than unmarried.
