Reviewed July 6, 2026. Educational guide, not a quote or coverage decision.

What the request usually means

Blanket Additional Insured requests often appear in leases, service agreements, contractor agreements, vendor onboarding packets, and event contracts.

This guide focuses on automatic additional insured wording when contracts require it.

  • Identify the party requesting the wording.
  • Find the required policy type and limit.
  • Check whether an endorsement is required.
  • Send the request to a licensed professional before signing if unclear.

Policy and contract review

A certificate alone may not satisfy every request. The policy forms and endorsements must support what the contract asks for.

  • Compare the contract clause with the declarations page.
  • Check additional insured, waiver, primary wording, and notice requests.
  • Track expiration dates and renewal certificates.

Records to keep

Keep the signed contract, issued certificate, endorsements, emails, and renewal reminders together.

  • Certificate holder name and address.
  • Policy numbers and effective dates.
  • Endorsement copies when issued.
