According to the definitions within a Personal Auto Policy, which individual is NOT considered a "family member"?

In the context of a Personal Auto Policy, the definition of a "family member" is typically limited to those individuals who have a close familial relationship with the insured. This often includes relatives who live with the insured, such as parents, children, siblings, and sometimes extended family depending on specific policy language.

The insured's ex-husband is not considered a "family member" under these definitions because, while he was previously related through marriage, that relationship has been legally severed. This creates a distinction from other relationships listed. The insured's daughter is included as she is a direct relative, and a roommate, despite not being a blood relation, is typically excluded from being considered family unless they are also a related by blood or marriage and living together. The insured's cousin may or may not be defined as a family member based on specific policy definitions, but they generally share a valid familial connection.

Thus, the ex-husband stands out as the correct answer, being the only individual listed who lacks an ongoing familial relationship with the insured according to standard definitions in a Personal Auto Policy.
