Plain-English meaning
A person or organization added to a liability policy for certain coverage rights under an endorsement.
The practical meaning should be confirmed in the document where the term appears. In contractual risk transfer, the same phrase can carry a more specific meaning than it does in a marketing summary.
Where you may see the term
Additional Insured may appear in one or more of these records:
- contract
- COI
- liability policy
- endorsement
What to verify
Ask how the contract wording and policy endorsement interact.
- Read the surrounding definition, insuring agreement, exclusion, condition, or endorsement.
- Record the form number, edition date, page, and policy period.
- Compare the policy term with any contract or certificate that uses similar wording.
- Ask for written clarification when the term changes a purchase, audit, claim, or contract decision.
Research note
Do not treat a glossary definition of Additional Insured as a coverage decision. Coverage depends on the full policy and facts. Use this page to identify the right document and the next question to ask.
