Request additional-insured status with a form for risk managers, contractors, and insurance coordinators. Collect the named insured, policy numbers, the additional-insured party’s legal name and address, the contract or job that requires the endorsement, requested wording (ongoing vs completed operations), and how the certificate should be delivered. Additional-insured grants are endorsement- and policy-specific; a certificate alone does not change coverage. Not insurance or legal advice; confirm current endorsements with the broker and carrier.

GL and any other lines the contract requires.

Description that will print on the COI.
