Operational context
What compliance teams should know.
CG 20 10 is the ongoing-operations additional-insured endorsement. It does not, by itself, cover completed-operations claims after the job.
If a certificate’s ADDL INSD box is checked but CG 20 10 is not attached, DueFiles flags the gap. A checkbox is not an endorsement.
Use the governing documents.
This reference is educational. A certificate summarizes represented coverage and does not amend a policy. Confirm requirements and coverage questions with the relevant contract, endorsement, insurer, broker, counsel, or qualified advisor.
