Coverage description
A National Council on Compensation Insurance (NCCI) standard form. It gives up the insurer's right to recover its workers compensation payments from the persons or organizations named in its schedule, but only where the insured's written contract requires that waiver.
Updated
What the form says
Key clauses from the original edition, which has not been revised, quoted as filed.
“We will not enforce our right against the person or organization named in the Schedule”
WC 00 03 13
Who the insurer gives up recovery against. The waiver reaches only the people or organizations entered in the schedule. Anyone else liable for a covered injury can still be pursued for what the insurer paid.
“applies only to the extent that you perform work under a written contract that requires you to obtain this agreement from us”
WC 00 03 13
Only contract-required waivers count. The waiver covers work done under a written contract that calls for it. Work for the same party outside that contract stays open to recovery.
“This agreement shall not operate directly or indirectly to benefit anyone not named in the Schedule”
WC 00 03 13
No benefit to anyone unnamed. Parties missing from the schedule, such as other contractors on the same job, cannot rely on the waiver.
