Hawaii Revised Statutes Division 1. Government § 386-124

Every policy of insurance issued by an insurer of an employer referred to in section 386-1 which covers the liability of the employer for compensation shall cover the entire liability of the employer to the employer's employees covered by the policy or contract, and provide for the deductible under section 386-100, at the option of the insured. The policy also shall contain a provision setting forth the right of the employees to enforce in their own names either by filing a separate claim or by making the insurance carrier a party to the original claim, the liability of the insurance carrier in whole or in part for the payment of the compensation. Payment in whole or in part of compensation by either the employer or the insurance carrier shall, to the extent thereof, be a bar to the recovery against the other of the amount so paid.

All insurance policies shall be of a standard form, the form to be designated and approved by the insurance commissioner. No policy of insurance different in form from the designated and approved form shall be approved by the director.
