Every GC encounters ACORD form questions at some point. Whether you are reviewing your first certificate of insurance or managing hundreds of subcontractor certificates across multiple projects, the same questions come up. This FAQ answers the ones we hear most often with clear, actionable answers.

Is an ACORD Form Legally Binding?

No. This is the single most misunderstood fact about ACORD forms in construction.

The ACORD 25 includes a disclaimer at the top of the form that reads (paraphrasing): the certificate is issued as information only and confers no rights upon the certificate holder. This language means the ACORD form is evidence that coverage existed at the time the certificate was generated. It is not a contract, not a guarantee, and not a policy.

A 2023 court decision in California reinforced this principle when a GC tried to enforce coverage based solely on an ACORD 25. The court ruled that the certificate holder had no standing to file a claim based on the certificate alone. The GC needed additional insured status on the actual policy.

What the ACORD form does do: it creates a paper trail showing you performed due diligence by collecting and reviewing proof of coverage. That paper trail matters in litigation. Courts look at whether the GC acted reasonably in verifying subcontractor insurance, and having ACORD forms on file demonstrates reasonable care.

Can a Certificate Holder File a Claim Based on an ACORD Form?

No. The certificate holder designation means you receive the certificate and cancellation notices. It does not give you claim rights under the sub's policy.

To file a claim under a sub's policy, you need one of two things:

Additional insured status granted by endorsement on the sub's GL or umbrella policy.
Named insured status (rare, typically only on owner-controlled insurance programs).

The distinction costs GCs money every year. A 2024 IRMI survey found that 28% of construction professionals incorrectly believed certificate holder status included claim filing rights.

Status	Receive Certificate	Receive Cancellation Notice	File Claims	Coverage Rights
Certificate Holder	Yes	Yes (if noted)	No	None
Additional Insured	Yes	Yes	Yes	Per endorsement terms
Named Insured	Yes	Yes	Yes	Full policy rights

Does the ACORD Form Guarantee Coverage?

No. A certificate confirms that coverage existed when the certificate was issued. It does not guarantee coverage at the time of a loss.

Three scenarios break the connection between the certificate and actual coverage:

Policy cancellation. The carrier may cancel the policy for non-payment after the certificate was issued. While the ACORD 25 includes provisions for cancellation notice, the standard 30-day notice window means there is a period where the certificate shows active coverage that no longer exists.

Policy endorsement changes. The sub or carrier may modify policy endorsements after the certificate was issued. Additional insured or waiver of subrogation endorsements can be removed mid-term without necessarily triggering a new certificate.

Coverage exclusions. The certificate shows limits and coverage types but does not detail exclusions. A GL policy with a construction defect exclusion or a pollution exclusion may appear fully compliant on the ACORD 25 while excluding the exact claims you face.

What Is the Difference Between ACORD 25 and ACORD 28?

The ACORD 25 covers liability insurance. The ACORD 28 covers commercial property insurance. They serve completely different purposes.

ACORD 25 (Certificate of Liability Insurance): Documents GL, auto, umbrella, and WC coverage. This is the standard certificate you collect from every sub. It proves the sub can pay for third-party bodily injury and property damage claims arising from their work.

ACORD 28 (Evidence of Commercial Property Insurance): Documents coverage on physical property, buildings, and business income. You collect this when a sub is responsible for insuring a structure, installed work, or high-value commercial property on or adjacent to your project.

Most GCs only need the ACORD 25 from every sub. The ACORD 28 applies in specific situations: design-build subs insuring their portion of the structure, subs leasing project-adjacent buildings for staging, or subs with contractual obligations to insure installed equipment.

When Was the ACORD 25 Last Revised?

The current ACORD 25 revision date is March 2016 (2016/03). The revision date appears in the lower-left corner of the form.

Key changes in the 2016 revision:

Added a cyber liability row to the coverage grid
Restructured the coverage section for clearer limit presentation
Updated cancellation notice provisions
Modified the disclaimer language

Prior versions (2014/01 and 2010/05) are still circulating. About 6% of certificates submitted to our platform use a pre-2016 form version. Always request reissuance on the current form. Older versions may lack fields that are now standard for compliance verification, and some older versions have different cancellation notice language that may reduce your notification rights.

How Long Is an ACORD Form Valid?

An ACORD form is valid for as long as the underlying policies remain active and unchanged. The certificate itself has no independent expiration date separate from the policies it documents.

In practice, this means the ACORD 25 is valid from its issuance date until the earliest policy expiration date listed on the form. If GL expires July 1 and WC expires October 1, the certificate is fully valid until July 1 and partially valid (WC only) from July 1 to October 1.

Set your tracking to the earliest expiration date across all policies on the certificate. Request renewals at least 30 days before that date.

Who Can Legally Issue an ACORD Form?

Only licensed insurance producers (agents or brokers) should issue ACORD certificates. The producer's name, license number, and contact information appear in the upper-left section of the ACORD 25.

Certificates issued by the subcontractor themselves, by unlicensed individuals, or by third parties carry no authority. They may not accurately reflect the actual policy terms.

How to verify the producer is legitimate: check the producer's license through your state Department of Insurance website. Enter the producer's name or license number. Confirm the license is active and covers the lines of insurance shown on the certificate.

About 4% of certificates in our system were initially submitted by someone other than the licensed producer. These certificates required re-issuance from an authorized source before acceptance.

Can an ACORD Form Be Altered After Issuance?

Paper ACORD forms can be altered with basic PDF editing tools. This is a known vulnerability in the paper certificate process. An estimated 7% of paper certificates contain some form of modification, ranging from date changes to limit alterations.

Digital ACORD certificates with electronic signatures resist tampering. The signature technology flags unauthorized modifications, making digital certificates more reliable for compliance verification.

To protect against altered certificates:

Contact the producer directly using the phone number from your records (not from the certificate) to confirm the certificate details.
Compare policy numbers with prior certificates from the same sub. Unexplained changes in policy numbers or carriers warrant verification.
Use digital verification when available. Some certificate management platforms verify certificates directly with the carrier's database.

What Should the Description of Operations Field Say?

The description of operations field on the ACORD 25 is the most flexible and most frequently botched section of the form. It should contain three elements specific to your project:

Project identification: Project name and address.
Additional insured confirmation: A statement that the certificate holder is additional insured per the attached endorsement, with endorsement form numbers (CG 20 10, CG 20 37, or equivalent).
Waiver of subrogation confirmation: A statement that waiver of subrogation applies to the listed policies.

A well-written description looks like this: "RE: [Project Name], [Project Address]. [Your Company] is additional insured per CG 20 10 07/04 and CG 20 37 07/04 attached to the GL policy. Waiver of subrogation applies to GL, auto, and WC policies per written contract."

A poor description: "For any and all operations." This generic language provides no project-specific protection and weakens your additional insured position in a dispute.

How Many ACORD Forms Does a Typical Project Require?

The answer depends on project size and the number of subcontractors.

Project Size	Typical Sub Count	ACORD 25s (Initial)	Renewals During Project	Total ACORD Transactions
Under $1M	5-10	5-10	2-5	7-15
$1M-$10M	15-40	15-40	10-25	25-65
$10M-$50M	40-100	40-100	30-70	70-170
$50M-$200M	100-250	100-250	80-200	180-450
Over $200M	250+	250+	200+	450+

These numbers only include ACORD 25s. Add ACORD 855 forms for WC details, ACORD 27/28 for property coverage, and ACORD 101 supplemental sheets, and the volume increases by 30-50%.

What Happens If I Accept a Non-Compliant ACORD Form?

Accepting a certificate that does not meet your contract requirements creates several risks:

Waived enforcement. If you consistently accept non-compliant certificates without objection, a court may find that you waived your contractual insurance requirements. This argument appears in approximately 15% of construction insurance disputes.

Coverage gaps. A certificate showing $1M GL when your contract requires $2M means you have $1M of uncovered exposure on that sub's work. If the sub causes a $1.5M loss, you eat the $500K difference.

Imputed negligence. In some jurisdictions, accepting inadequate coverage when you had the opportunity and contractual right to require more can be considered negligent. This can affect your own liability in a claim.

Do Electronic ACORD Forms Have the Same Legal Standing as Paper?

Yes. ACORD supports electronic certificate issuance, and electronic certificates carry the same legal standing as paper versions under the E-SIGN Act (federal) and UETA (adopted by 49 states).

Electronic certificates offer advantages over paper:

Tamper detection through electronic signatures
Direct carrier verification capabilities
Automated expiration tracking
Reduced processing time (minutes vs. days)

As of 2025, approximately 44% of construction certificates are issued electronically. The adoption rate is increasing by roughly 8% per year as more carriers and brokers support digital issuance.

Frequently Asked Questions

Can I require a specific ACORD form version from my subcontractors? Yes. Include the form version requirement in your subcontract insurance exhibit. Specify "ACORD 25 (2016/03 revision or current)" to ensure you receive the most up-to-date form with all current fields.

What if the ACORD form shows a policy that expired yesterday? Contact the sub immediately. A 1-day gap in coverage is still a gap. Do not allow the sub to work until you have a certificate showing active coverage. Most policy renewals can be backdated to the expiration date, eliminating the gap retroactively.

Should I keep ACORD forms from subs who completed their work years ago? Yes. Retain certificates for the full statute of repose in your project state, which ranges from 4 to 15 years depending on the state. Completed operations claims can arise years after the work is done, and you need the certificate that was in effect when the work was performed.

Can an ACORD form from one project be used for another project? Only if the description of operations covers both projects and the certificate period spans both projects. Best practice is to collect project-specific certificates with project-specific descriptions. Generic certificates weaken your compliance position.

What does "SIR applies" mean on an ACORD form? SIR stands for Self-Insured Retention. It means the sub pays the first portion of any claim (the SIR amount) before insurance kicks in. If the SIR is $50,000 and the sub cannot pay it, the carrier may not respond. Verify SIR amounts and confirm the sub has the financial capacity to fund them.

Is there a standard turnaround time for ACORD form requests? Industry norm is 24-48 hours for a standard certificate request. Complex requests with special endorsements or multiple additional insured parties may take 3-5 business days. If turnaround consistently exceeds a week, the sub should address the issue with their broker.
