Conn. Gen. Stat. § 31-287: Provisions required in liability insurance policies.

No policy of insurance against liability under this chapter, except as provided in section 31-284, shall be made unless the same covers the entire liability of the employer thereunder and contains an agreement by the insurer that, as between the employee and the insurer, notice or knowledge of the occurrence of injury by the insured shall be deemed notice or knowledge by the insurer, that jurisdiction of the insured for the purposes of this chapter shall be jurisdiction of the insurer and the insurer shall in all things be bound by and subject to the findings, awards and judgments rendered against such insured; and also that, if the insured becomes insolvent or is discharged in bankruptcy during the period that the policy is in operation, or the compensation, or any part of it, is due and unpaid or if an execution upon a judgment for compensation is returned unsatisfied, an injured employee or other person entitled to compensation under the provisions of this chapter may enforce his claim to compensation against the insurer to the same extent that the insured could have enforced his claim against such insurer had he paid compensation.
