Family expense disability insurance is that form of disability insurance insuring more than one person and issued to the head of a family or his spouse indemnifying him, or his spouse, or both, against loss due to disability of one or more persons dependent at the time of issuance upon him, or his spouse, or both, and may include indemnification on account of his own disability and disability of his spouse whether or not either is dependent on the other.
Where such a policy provides for payment for expenses incurred, expenses incurred by or upon behalf of any person covered by the policy shall be deemed incurred by the person to whom or at whose direction benefits are payable under the policy.
No question as to whether or not any person is the head of the family or his spouse, or is a child or dependent of either shall relieve the insurer of any liability it otherwise would have under the policy.
Where such a policy indemnifies a spouse alone or a spouse and the head of the family, references in the policy to the head of the family shall be deemed to refer to or include the spouse.
