Why a Certificate of Insurance Isn’t Always Enough

February 18, 20265 min read

If you’ve ever been asked to provide a Certificate of Insurance (COI), you may have assumed:

“I have coverage. I’ll just send over the certificate.”

Then comes the follow-up:

“We also need to be listed as Additional Insured.”

That’s when the confusion usually begins.

Why isn’t proof of insurance enough?

Let’s clarify what a certificate actually does — and why property owners, landlords, event hosts, and contract partners often require more.

What Is a Certificate of Insurance?

A Certificate of Insurance is a document that provides evidence of active insurance coverage.

It typically shows:

  • The named insured (your business)

  • Policy types (General Liability, Workers Comp, Auto, etc.)

  • Policy limits

  • Policy numbers

  • Effective and expiration dates

  • Carrier information

Most certificates are issued on a standardized ACORD form.

Important: A Certificate Does Not Change Coverage

A COI does not:

  • Modify your policy

  • Add coverage

  • Extend protection to the certificate holder

  • Override policy exclusions

  • Guarantee contract compliance

It is informational only.

The language on standard ACORD forms specifically states that the certificate does not amend, extend, or alter the coverage afforded by the policies listed.

Who Can Issue or Edit a Certificate of Insurance?

Certificates must be issued by:

  • The insurance carrier

  • A licensed insurance agent or broker authorized to represent the carrier

Business owners cannot legally create, alter, or modify their own certificate of insurance.

Editing a certificate yourself — even something that seems minor — can:

  • Void the validity of the document

  • Create potential fraud concerns

  • Put your business in breach of contract

If a certificate needs specific wording or evidence of endorsements, that request must go through your licensed insurance professional.

Why Many Contracts Require More Than a Certificate

When a property owner or event host asks to be listed as Additional Insured, they are not just verifying you have coverage.

They are requesting to be extended certain liability protection under your policy for claims arising out of your work or operations.

In simple terms:

They want your insurance to respond first if they are pulled into a claim because of something you did.

A certificate alone does not provide that protection.

An endorsement does.

Real-World Example

You are a contractor performing work at a commercial property.

A visitor trips over debris related to your project and sues both you and the property owner.

If the property owner is properly listed as Additional Insured:

  • Your General Liability policy may defend both parties.

  • Your coverage may respond to claims arising out of your operations.

If they are not listed:

  • Their own insurance may respond first.

  • Their carrier may seek reimbursement from you.

  • Contract disputes may follow.

This is why Additional Insured status is often mandatory in commercial agreements.

What Does “Additional Insured” Actually Mean?

Being named as Additional Insured generally extends liability protection to the third party for claims arising out of your work.

It does not:

  • Provide them full control over your policy

  • Cover their independent negligence

  • Replace their own insurance requirements

It simply transfers certain risk exposures back to the party performing the work.

Common Add-Ons Often Required in Contracts

In addition to Additional Insured status, contracts may require:

Waiver of Subrogation

Prevents your insurance carrier from pursuing recovery against the other party after paying a claim on your behalf.

In practical terms, this means that if your insurer pays out for a covered loss, they agree not to seek reimbursement from the landlord, property owner, or contracting party - even if they were partially responsible. Many commercial leases and construction agreements require this to reduce legal disputes between insurers.

Primary and Non-Contributory Wording

States that your policy responds first before the Additional Insured’s policy contributes.

Without this wording, both insurance carriers may share responsibility for a claim. When a contract requires “primary and non-contributory,” it ensures your policy is considered the first line of defense for claims arising out of your operations - limiting the other party’s policy involvement.

Ongoing and Completed Operations Coverage

Extends protection for claims arising during active work and after the project is finished.

Ongoing operations coverage applies while work is in progress. Completed operations coverage applies after the job has been completed, sometimes months or even years later. Many contracts require both to ensure protection continues beyond the day the project wraps up.

Specific Endorsement Forms (Often ISO Forms)

Many contracts reference specific endorsement numbers (often standardized forms developed by the Insurance Services Office, or “ISO”). These forms define exactly how and when Additional Insured coverage applies - such as whether it includes ongoing operations, completed operations, or both.

Per Project Aggregate Limits

Separates policy limits per project rather than sharing one aggregate limit across all of your operations.

Without a per-project aggregate, multiple claims across different jobs could reduce the total limit available. This endorsement isolates coverage limits for a specific project, which is particularly important for larger construction or higher-risk contracts.

When Are These Requirements Necessary?

It depends on:

  • The size and scope of the project

  • The type of work being performed

  • The contract language

  • The risk management policies of the property owner or venue

A small vendor event may only require proof of coverage and Additional Insured status.

A commercial construction contract may require multiple endorsements and specific wording.

The key is reviewing the contract before signing — not after a claim.

Why This Matters for Business Owners

A Certificate of Insurance proves you have coverage.

It does not guarantee your policy satisfies the contract you signed.

If a contract requires Additional Insured status, Waiver of Subrogation, Primary and Non-Contributory wording, or specific endorsement forms — and your policy does not include them — you may be exposed to:

  • Breach of contract disputes

  • Uninsured defense costs

  • Carrier denial based on policy language

Understanding this before work begins is far less expensive than discovering it during a claim.
