I am trustee of a family trust that holds title to a single family home. My brother and I are beneficiaries of the trust. My brother lives there with his girlfriend. The house is insured with a standard home owner policy with the insured being the trust and my brother as an additional insured. There is 500K of personal liability coverage on the policy. I am concerned if the girlfriend had an accident on the property and filed a claim or lawsuit against the trust or me as trustee. Will the policy cover such a situation? She is not a tenant since there is no lease in place.
