A certificate of insurance is a one-page document, issued by your insurance agent or broker, that proves to a third party you carry active insurance and summarizes the key terms of your policy. Landlords, general contractors, lenders, and government agencies routinely require one before you can sign a lease, start a project, or close a loan. It does not give the recipient a copy of your full policy, and it does not, by itself, give them any rights under your coverage.
What’s on the Document
Nearly all commercial certificates in the United States use the ACORD 25 form, a standardized template from the Association for Cooperative Operations Research and Development. The header carries the issue date, a certificate number, and the producer — the agent or brokerage that generated the document on your behalf.
Below that, each insurer providing coverage is listed as Insurer A, Insurer B, and so on, with the carrier’s NAIC number assigned by the National Association of Insurance Commissioners. That number lets the recipient look up the carrier’s license and financial condition. Your legal name and address appear in a separate block and must match your policy records exactly. A small discrepancy, such as a trade name instead of the registered entity name, is enough to get the certificate rejected.
The body of the form breaks coverage into categories, each with its own policy number, effective and expiration dates, and dollar limits. A typical ACORD 25 shows:
- Commercial general liability, including per-occurrence limit, general aggregate, personal and advertising injury, medical expense, and damage to rented premises.
- Automobile liability, as a combined single limit per accident or separate bodily injury and property damage limits.
- Umbrella or excess liability, with per-occurrence and aggregate limits sitting above the underlying policies.
- Workers’ compensation and employers’ liability at statutory limits, plus per-accident and per-employee disease limits.
At the bottom is the certificate holder block, where the requesting party’s full legal name and mailing address go, along with a description of operations field for project details and endorsement references. If the dates on the certificate fall outside the policy period, the document is useless, and any contract requiring proof of insurance may be considered breached.
Endorsements That Actually Give the Holder Rights
The certificate itself is just a snapshot. Real protection comes from endorsements attached to the underlying policy, and three show up in contracts constantly. Misunderstanding them is where most disputes begin.
Additional Insured Status
When a contract requires you to name someone as an additional insured, your policy has to be endorsed so that party receives liability protection under your coverage for claims arising from your work. Being named as the certificate holder is not the same thing. The certificate holder only receives the document; an additional insured actually has coverage rights under your policy. The ACORD 25 itself warns that if the certificate holder is an additional insured, the policy must be endorsed to provide that status, and a statement on the certificate alone does not create those rights.1New York State Department of Financial Services.

Waiver of Subrogation
After your insurer pays a claim, it normally has the legal right to sue whoever caused the loss to recover what it paid. A waiver of subrogation surrenders that right against a specific party. Construction contracts, commercial leases, and joint ventures almost always require the waiver, so that your insurer cannot turn around and sue the other side after a covered loss.
Primary and Non-Contributory
When more than one policy could respond to the same claim, a dispute can erupt over whose pays first. Primary and non-contributory language forces your policy to respond first, up to its limits, without requiring the additional insured’s own policy to contribute. Property owners and general contractors commonly require this from subcontractors so their own coverage stays untouched unless your limits run out.
What the Certificate Cannot Do
This is where people get burned. A certificate is informational only. It cannot amend, extend, or alter the coverage your policy actually provides. If the certificate lists a feature your policy does not include, the policy controls and the certificate is simply wrong. A majority of states have codified this principle, and the ACORD 25 includes a disclaimer stating the certificate “does not amend, extend or alter the coverage afforded by the policies.”2New York State Department of Financial Services.

State certificate-of-insurance laws also generally prohibit anyone from demanding that a certificate contain terms the underlying policy does not. A requesting party that pressures an agent to add language beyond what the policy provides is violating those statutes in most jurisdictions. If you are the one receiving the certificate, the only way to confirm you have the protections you think you have is to ask for copies of the actual endorsements.
Cancellation Notice Is Not Automatic
Older ACORD 25 forms once committed the insurer to a set number of days’ notice before cancellation. The current version removed that commitment. The standard language now reads: “Should any of the above described policies be cancelled before the expiration date thereof, notice will be delivered in accordance with the policy provisions.”1New York State Department of Financial Services. ACORD 25 (2025/12) – Certificate of Liability Insurance The insurer follows whatever the policy says, and most policies only require notice to the named insured, not to every certificate holder.
If you need guaranteed notice as a certificate holder, you have to require a specific notice-of-cancellation endorsement on the policy itself. Without it, neither the insurer nor the agent is obligated to tell you the coverage lapsed. Relying on the certificate alone for this is one of the most expensive mistakes in commercial contracting.
Which ACORD Form Fits the Situation
ACORD 25 is the one most people encounter, but it only covers liability. Other situations call for different forms, and submitting the wrong one is a common cause of rejection.
- ACORD 25 (Certificate of Liability Insurance): general liability, commercial auto, umbrella, and workers’ compensation. The default for vendor qualification, contractor agreements, and service contracts.
- ACORD 28 (Evidence of Commercial Property Insurance): used when the requesting party has a direct insurable interest in the property, such as a mortgagee or a landlord whose building is covered. This replaced the older ACORD 27 for most commercial property situations.
- ACORD 24 (Certificate of Property Insurance): used when the requesting party does not have a direct insurable interest but still needs verification that property coverage exists, such as in condominium associations or equipment leases.
A mortgage lender will not accept an ACORD 25 as proof of property coverage, and a general contractor checking your liability will not accept an ACORD 28. Match the form to the coverage being verified.
How to Request One
You do not create a certificate yourself. Your agent or broker generates it from your current policy data. Start by reading the insurance requirements section of your contract or lease carefully so you know exactly what the requesting party needs.
Before contacting your agent, pull your current policy declarations page and the requesting party’s requirements together. Pay attention to the required limits, any endorsements being demanded, and the exact legal name and mailing address of the certificate holder. Errors in that name are the single most common reason certificates get kicked back.
When you send the request, include:
- The certificate holder’s full legal name and mailing address.
- The specific endorsements required, such as additional insured, waiver of subrogation, or primary and non-contributory.
- Any project description or contract number that should appear in the description of operations field.
- The deadline by which the requesting party needs the document.
If the contract calls for endorsements your policy does not currently carry, your agent has to request them from the insurer first, which may add premium. Most agents now generate certificates electronically and can turn around a straightforward request the same day. Requests that require new endorsements take longer because underwriting has to approve the change first.
Once the certificate is issued, your agent typically emails the PDF directly to the certificate holder, or uploads it to a tracking portal if the recipient uses one. Confirm receipt, keep your own copy, and set a reminder a few weeks before your policy renewal so you can send an updated certificate before the dates on the old one expire.
If You Just Need Proof of Auto Insurance
Personal auto verification works differently. Most states now use electronic insurance verification systems in which your insurer reports your coverage status directly to the state motor vehicle agency, so you generally do not submit a certificate at all. In states still transitioning, you may need to present a physical or digital insurance ID card at registration or renewal, which your insurer provides automatically when your policy is issued. If the motor vehicle agency sends you a notice questioning your coverage, follow its instructions, which usually mean submitting your insurance details online or asking your insurer to report electronically.
Fraud Risk
Issuing or requesting a certificate that misrepresents the underlying coverage is illegal. A majority of states have statutes making it unlawful for agents, policyholders, or requesting parties to issue or demand certificates containing false or misleading information. Penalties range from fines and license revocation for agents to criminal charges depending on intent.
Altering a certificate after issue, fabricating one for coverage that does not exist, or inflating limits beyond the policy all count as insurance fraud. Even a seemingly small change, like adjusting a date to cover a gap, exposes you to prosecution and voids any coverage the certificate was supposed to represent. If a certificate you received looks off, contact the producing agent listed on the form to verify it before relying on it.
