Certificate holder vs additional insured
5 min read
Reviewed by Chance Sowers, AFIS, CEO of AInsure
A certificate holder is someone who was sent a copy of a certificate. An additional insured has actual coverage under someone else’s policy. Appearing in the certificate holder box grants you nothing.
This is the most consequential misunderstanding in the whole certificate process, and it is easy to see why it happens. Both terms appear on the same one-page form, often within an inch of each other, and both sound like they describe a relationship to the policy. Only one of them is.
The difference in one table
| Certificate holder | Additional insured | |
|---|---|---|
| What it means | You were sent this document. | You are covered under the policy, for the scope the endorsement defines. |
| Where it lives | A box on the certificate. | An endorsement on the actual policy. |
| Who creates it | Whoever typed the certificate. | The insurer, by issuing the endorsement. |
| Can you make a claim? | No. | Yes, within what the endorsement grants. |
| Does the certificate prove it? | It is the certificate. | No — it only asserts that an endorsement exists. |
Why this costs people money
The scenario is ordinary. A property manager requires their contractors to name them as an additional insured. A contractor’s agent issues a certificate with the property manager in the certificate holder box. Everyone files it. Two years later someone is injured, the property manager is named in the suit, and they tender the claim to the contractor’s insurer — who declines, because no endorsement naming them was ever issued.
The certificate was genuine the entire time. It simply never said what everyone assumed it said.
How to check which one you have
1. Look in the description of operations
Additional insured status, when it exists, is normally referenced in the free-text box in the middle of the form — often naming the specific endorsement form number. Its absence is a strong signal. Its presence is an assertion, not proof.
2. Ask for the endorsement
This is the actual answer. Request a copy of the additional insured endorsement itself. It is a real document issued by the insurer, it names you, and it defines the scope of what you get. If the stakes justify requiring the status, they justify asking for the page that grants it.
3. Read what the endorsement actually covers
Additional insured endorsements vary considerably. Some cover only liability arising out of the named insured’s ongoing operations and end when the work does; others extend to completed operations. Some are limited to vicarious liability. “We are an additional insured” is the beginning of the question, not the end.
Two related terms worth knowing
- Waiver of subrogation. The insurer gives up its right to come after you to recover what it paid. Also an endorsement, also frequently asserted in the description box.
- Primary and non-contributory. Their policy pays first, and does not ask yours to share. Without it, two insurers can spend a long time arguing about order while nothing gets paid.
All three follow the same pattern: the certificate mentions them, the endorsement grants them, and only one of those two is a contract.
