Short answer
Certificate holder vs additional insured comes down to rights. A certificate holder receives proof that you carry insurance and has no rights under the policy. An additional insured is added to the policy and can seek coverage for certain claims tied to your work. Additional insured status is mainly a general liability feature, so check which policy the contract refers to.
What a certificate holder receives
A certificate holder is the party listed on the certificate of insurance. The certificate shows that coverage exists, the policy numbers, the limits and the dates.
It doesn’t give the holder any rights under your policy. The certificate is a summary, and the policy itself controls. Our guide on how to read a COI explains each section.
What an additional insured gets
An additional insured is a party added to your policy by endorsement. They can seek coverage when they are pulled into a claim because of something you did. It doesn’t cover them for their own mistakes.
Most general liability policies use a blanket additional insured endorsement. It applies to parties you agreed in writing to add. A certificate that says additional insured doesn’t create coverage if the endorsement or agreement doesn’t support it.
Certificate holder vs additional insured: which does your client need?
Contracts often use the two terms loosely. A client may ask to be named additional insured when a certificate would satisfy the requirement. Others need the endorsement.
Read the contract for the exact wording. Look for words like additional insured, waiver of subrogation or primary and non-contributory. If the language is unclear, ask the client what they are trying to receive.
A simple example
A client’s contract says the owner must receive proof of insurance and be named additional insured. The firm carries professional liability and general liability. The certificate can list the owner as certificate holder on all policies. Additional insured status would usually apply to general liability, and our article on adding an additional insured to professional liability explains why professional liability rarely offers it.
Which policies provide additional insured status
Additional insured status is mainly a general liability feature. It can also apply to auto and umbrella policies, depending on the terms. Read our article on general liability for architects to see how those policies work.
If your firm carries no general liability policy, a client who needs additional insured status may be asking for coverage you don’t have. Our insurance requirements check can help you compare a contract with your policies.
How to request a COI
A request goes faster when it includes the right details. Send your insurance agent:
- The certificate holder’s full legal name and address.
- The project name or description, if the contract asks for one.
- The contract language that lists the insurance requirements.
- Any endorsements requested, such as additional insured or waiver of subrogation.
- The date the client needs the certificate.
Our certificates of insurance page explains how to request one. Policies and endorsements control what the certificate can say.
What to check about certificate holder vs additional insured
- Does the contract ask for proof of insurance, additional insured status or both?
- Which policy does the requirement apply to?
- Does your policy offer the endorsement the client asks for?
- Is there a written agreement that supports the additional insured request?
- Does the certificate name the right legal entity and project?
