General Liability FAQs

What is the difference between a certificate of insurance and additional insured status?

Quick answer: Additional insured status means another party is added to your policy to receive liability protection for claims arising from your work.

A certificate of insurance and additional insured status are two different things, and the difference matters a great deal. A certificate proves coverage exists. Additional insured status actually extends some of that coverage to another party. Many Georgia business owners think a certificate gives a client real protection, but on its own it does not.

What is a certificate of insurance?

A certificate of insurance, often called a COI, is a one-page summary of your policy. It lists your coverages, limits, and policy dates. It is proof that you bought insurance, and contractors, landlords, and clients request it as evidence. A certificate does not change your policy or give the holder any right to file a claim against it. It is informational only. Certificates are issued by the agent or broker on the policy; see how carriers and agents differ in the insurance process if you are unsure who to contact when a certificate is requested.

What is additional insured status?

When you add a party as an additional insured, your policy is changed by an endorsement so that the other party is actually protected under your liability coverage for claims arising from your work. If a customer sues both you and your general contractor over something your crew did, the additional insured endorsement lets the contractor turn to your policy for defense costs and damages.

What is the practical difference between a COI and additional insured status?

The distinction comes down to coverage versus proof:

  • A certificate of insurance proves you have coverage but grants no coverage to the holder.
  • Additional insured status actually extends your liability coverage to the named party.
  • Both are often required together, because a contract may demand a certificate that also confirms additional insured status.

For example, a Marietta electrical subcontractor signs a contract requiring the general contractor to be named as an additional insured. A wiring mistake later causes a $90,000 fire claim. Because the contractor was properly added by endorsement, the general liability policy can defend and cover the contractor, satisfying the contract and preserving the working relationship. Without that endorsement, a certificate alone would not have provided any coverage to the contractor.

Does the type of liability policy affect additional insured coverage?

The policy type affects how additional insured status works in practice. Under an occurrence-based policy, the additional insured is covered for incidents that happen during the policy period, even if the claim is filed years later. Under a claims-made policy, coverage depends on when the claim is actually reported. Understanding the difference between claims-made and occurrence policies matters when contracts specify which type is required.

Does additional insured status cover professional or advice-related claims?

General liability policies, and the additional insured endorsements that extend them, cover bodily injury and property damage. They do not cover claims that arise from professional advice or services. For example, an architect added as an additional insured on a contractor's general liability policy would not have coverage for a design error claim through that endorsement. That type of exposure requires a separate professional liability policy. See what professional liability insurance covers if your work involves advice, design, or professional services.

Read contracts carefully, because the wording typically specifies which endorsements are required. A licensed advisor can confirm whether your certificates and endorsements match your contract obligations. Request a free coverage review to go over the details.
