The certificate of insurance, and the four things it will not tell you

A certificate of insurance is a one-page report that a policy exists. It is not the policy. The standard form, ACORD 25, opens by saying in capital letters that it confers no rights on the party holding it, amends nothing, and is not a contract. Four things it cannot tell you: whether the holder was actually added to the policy, what the policy excludes, how much of the limit is still there, and whether anyone has to tell you if it is cancelled. This page is about the document. What the coverages themselves do is a different question.

What the form says about itself

Start with the definition, because it is narrower than the way the document gets used. IRMI, the insurance reference publisher, defines a certificate of insurance as "a document providing evidence that certain general types of insurance coverages and limits have been purchased by the party required to furnish the certificate" (IRMI, certificate of insurance). Evidence, and general types. A certificate holder, in the same glossary, is just "the entity that is provided a certificate of insurance as evidence of the insurance maintained by another entity" (IRMI, certificate holder). Being handed the paper is the whole of what that status means.

The form agrees with the glossary, at the top, in capitals. The ACORD 25 Certificate of Liability Insurance, 2014/01 edition, opens: "THIS CERTIFICATE IS ISSUED AS A MATTER OF INFORMATION ONLY AND CONFERS NO RIGHTS UPON THE CERTIFICATE HOLDER. THIS CERTIFICATE DOES NOT AFFIRMATIVELY OR NEGATIVELY AMEND, EXTEND OR ALTER THE COVERAGE AFFORDED BY THE POLICIES BELOW. THIS CERTIFICATE OF INSURANCE DOES NOT CONSTITUTE A CONTRACT BETWEEN THE ISSUING INSURER(S), AUTHORIZED REPRESENTATIVE OR PRODUCER, AND THE CERTIFICATE HOLDER." That text comes from a completed sample published by the City of New York (ACORD 25 (2014/01), sample published by NYC Department of Cultural Affairs); the form belongs to ACORD, and a later edition is on the New York Department of Financial Services list of approved certificates (NY DFS, ACORD 25 (2025/12)). The wording quoted here is the 2014/01 edition.

Read casually that paragraph looks like an insurer covering itself. It is not. New York's insurance regulator, asked about exactly this language, wrote that the clause "merely conforms the certificate to the Insurance Law," which does not permit an insurer to make a contract of insurance other than as expressed in the policy; a certificate that restated the policy needs no filing, while a certificate that tried to amend or expand the policy would have to be filed with the Superintendent (NY DFS, OGC Opinion No. 00-09-04). That is one state's counsel reading one clause, in 2000, and not a national rule. But it explains the disclaimer better than the disclaimer explains itself: a document that is not a policy is not allowed to do a policy's work.

Certificate holder is a mailing address. Additional insured is a policy status.

Certificate holder against additional insured

Source: ACORD 25 (2014/01) form text and IRMI's definition of additional insured

The form settles the argument itself: "If the certificate holder is an ADDITIONAL INSURED, the policy(ies) must be endorsed. A statement on this certificate does not confer rights to the certificate holder in lieu of such endorsement(s)." Filing the certificate and never asking for the endorsement collects the receipt and not the thing.

This is the mistake worth the most money. An additional insured, in IRMI's definition, is "a person or organization not automatically included as an insured under an insurance policy who is included or added as an insured under the policy at the request of the named insured" (IRMI, additional insured). Added under the policy. That happens by endorsement, a document that changes the policy, issued by the insurer. The certificate holder box changes nothing; it records who got a copy.

The ACORD 25 prints the warning directly under the main disclaimer: "IMPORTANT: If the certificate holder is an ADDITIONAL INSURED, the policy(ies) must be endorsed. If SUBROGATION IS WAIVED, subject to the terms and conditions of the policy, certain policies may require an endorsement. A statement on this certificate does not confer rights to the certificate holder in lieu of such endorsement(s)." The form is telling the reader that the checkbox in the ADDL INSD column, and any sentence typed into the description of operations box, are reports of an endorsement rather than substitutes for one.

So a general contractor who wrote an additional insured requirement into a subcontract, collected a certificate with the box ticked, and filed it, has collected the receipt and not the thing. The request that closes the gap is short: send the additional insured endorsement, by form number, with the edition date. A subcontractor being asked for it is being asked correctly. Which party owes what to whom is the subject of the general contractor and subcontractor guide, and the coverage the endorsement attaches to is on the general liability page.

Two things the certificate hides even when everything on it is true

The limit may already be spent. The COVERAGES box states that the insurance afforded is "SUBJECT TO ALL THE TERMS, EXCLUSIONS AND CONDITIONS OF SUCH POLICIES," and then adds the sentence that undoes the comfort of the numbers in the right-hand column: "LIMITS SHOWN MAY HAVE BEEN REDUCED BY PAID CLAIMS." The general aggregate printed on the form is the limit the policy was issued with. Nothing on the certificate reports what has been paid out of it during the policy year, and a general liability aggregate is a pool that drains.

The exclusions are not on it. A certificate names coverages and limits. It does not name the endorsements that carve holes in them, and for a contractor those are where the argument lives: the exclusion for damage to property in your care, custody, or control (IRMI, care, custody, or control), the pollution exclusion in the post-1986 general liability form, a residential or new-construction exclusion, a height or depth restriction, a subcontractor warranty. None of that appears on the ACORD 25.

One state has actually written this problem into its rules. Texas requires private security company license holders to file evidence of general liability insurance, and the rule tells the applicant what the evidence has to show: that the insurance applies to the licensed conduct, the statutory minimum limits broken out line by line, and "the exclusions or endorsements specific to the activity for which the licensee is licensed, or that there are no such exclusions or endorsements" (37 TAC 35.27(a); Occupations Code 1702.124 carries the limits). A regulator that has read enough certificates asks for the exclusions in writing. A contractor reviewing a sub's paper can ask for the same thing.

The cancellation notice you probably do not have

Older certificates carried a promise that the insurer would "endeavor to mail" notice before cancelling. Current ones do not promise even that. The ACORD 25 (2014/01) cancellation box 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." That sentence points back at the policy. If the policy owes the certificate holder nothing, the certificate adds nothing.

Watch what parties who genuinely need the notice do instead. Texas licensing forms ask for it and ask politely: the certificate of insurance forms TDLR publishes for electrical contractors and for air conditioning and refrigeration contractors both ask the carrier to endeavor to notify the department at least 30 days before cancellation or non-renewal. Illinois writes it into the policy instead. Under 68 Ill. Adm. Code 1460.20, a licensed roofing contractor's liability policy "shall provide that it cannot be cancelled except upon written notification to the Division at least 30 days prior to the date of cancellation," with the bond rule at 1460.30 asking 60 days (68 Ill. Adm. Code 1460; IDFPR, roofing contractors). The difference between a request on a form and a condition in a policy is the difference between hoping and knowing, and it is worth naming when a contract asks you for 30-day notice of cancellation. See what else Illinois attaches to that license on the roofing contractor insurance page.

When the certificate holder is a licensing agency

Most certificates go to a customer. Some go to the state, and those have rules about the paper itself that are worth knowing before a license renewal stalls. TDLR's certificate of insurance forms for Texas electrical contractors and for air conditioning and refrigeration contractors both state that binders and declarations pages are not accepted: the department wants its own form, completed by the carrier or agent. The electrical rule, 16 TAC 73.40(b), requires the certificate "when applying for initial and renewal licenses and upon request of the department," so it is not a one-time filing. Both rules also require a licensee to hand over the carrier name, policy number, and the agent's name, address and phone number to any customer who asks (16 TAC 73.40, 16 TAC 75.40). Those two trades have their own pages here: Texas electrician insurance and Texas HVAC contractor insurance, with the license rule laid out at length in the electrical contractor insurance requirements guide.

New Jersey makes the certificate a gate rather than a formality. Home improvement contractors register with the Division of Consumer Affairs, registration requires proof of commercial general liability insurance of at least $500,000 per occurrence, and the Division does not process an application that arrives without the insurance certificate (NJ Division of Consumer Affairs, HIC registration). In that state the certificate is not evidence of a decision you made; it is the condition of being allowed to work. What a New Jersey operator does about it is on the New Jersey handyman insurance page.

Two guides sit next to this one. If the question underneath the certificate is what the number on it is going to be, read what actually sets a contractor's insurance cost. If it is which policies you are supposed to have in the first place, read what insurance a contractor needs. And if a client used the phrase "bonded and insured," that is a third thing again, explained in the bonded and insured guide.

Frequently Asked Questions

What is a contractor certificate of insurance?
It is a one-page document, almost always the ACORD 25 Certificate of Liability Insurance, that reports which policies a contractor has bought, with whom, for what limits, and through what dates. IRMI defines it as evidence that certain general types of coverages and limits have been purchased by the party required to furnish it. The words doing the work there are "evidence" and "general types". The certificate reports that a policy exists. It is not the policy, and it does not carry the policy's terms.
Does a certificate of insurance give the certificate holder any rights?
The form answers this itself, in capitals, at the top: the certificate "is issued as a matter of information only and confers no rights upon the certificate holder," it "does not affirmatively or negatively amend, extend or alter the coverage afforded by the policies below," and it "does not constitute a contract between the issuing insurer(s), authorized representative or producer, and the certificate holder." That is the ACORD 25 (2014/01) edition. New York's insurance regulator has explained that the clause is not the insurer hedging; it conforms the document to a law that does not let an insurer make a contract of insurance except as expressed in the policy.
Is a certificate holder the same as an additional insured?
No, and the difference is the reason most certificate disputes happen. A certificate holder is simply the entity that was handed the certificate. An additional insured, in IRMI's definition, is a person or organization not automatically included as an insured who is added to the policy at the named insured's request. That addition happens by endorsement on the policy. The ACORD 25 says so on its own face: if the certificate holder is an additional insured, the policy must be endorsed, and a statement on the certificate does not confer rights in lieu of the endorsement. Ask for the endorsement, not the box.
Does the certificate prove the limits are still there?
It does not, and it says so. In the COVERAGES box the ACORD 25 states that the insurance is subject to all the terms, exclusions and conditions of the policies, and then adds one sentence almost nobody reads: "LIMITS SHOWN MAY HAVE BEEN REDUCED BY PAID CLAIMS." A certificate showing a $1,000,000 aggregate is reporting the limit the policy was written with, not the limit that is left after a year of claims. Nothing on the form reports what has been paid out.
Does a certificate mean I will be told if the policy is cancelled?
Not by itself. The cancellation box on the ACORD 25 (2014/01) promises only that notice "will be delivered in accordance with the policy provisions," which points back at the policy and creates no obligation of its own. Parties who want notice have to get it into the policy. Illinois does exactly that for roofing contractors: by rule the liability policy itself must provide that it cannot be cancelled except on 30 days' written notice to the Division. That is a policy term. A line on a certificate is not.
