The waiver of subrogation wording on a certificate of insurance shows up in two spots on the ACORD 25 form: a narrow checkbox column labeled “SUBR WVD” next to each coverage line, and a text block near the bottom called “Description of Operations / Locations / Vehicles.” The checkbox tells you a waiver exists for that line. The text block tells you who it protects and under what conditions. Both need to be right, and both are only a summary of the real protection, which lives in the policy endorsement behind the certificate.
The Two Places the Waiver Appears on an ACORD 25
The ACORD 25 is the standard proof-of-coverage form across the insurance industry. Each coverage line listed on the form has a row of narrow columns to the left of the policy limits. One of those columns is labeled “SUBR WVD,” short for “Subrogation Waived.” When the insurer has agreed to waive its subrogation rights for that line, the agent marks the column with an “X” or a “Y.” A blank column means no waiver is in place for that coverage line.
The lower portion of the form contains the Description of Operations field. This is where agents spell out what a single checkbox can’t convey: the name of the protected party, the project or contract involved, and the conditions under which the waiver applies. If the SUBR WVD box is checked but the Description of Operations field says nothing about the waiver, raise it with the agent before you accept the certificate.
What the Description of Operations Wording Should Say
Agents use fairly standardized language to summarize the endorsement. A typical entry reads: “Waiver of subrogation is granted in favor of [Certificate Holder Name] as required by written contract.” Some versions add “with respect to [project name or contract number]” and “to the extent permitted by law.” That last phrase is not filler. It reflects real limits in several states where anti-indemnity laws restrict or void certain waivers.
The wording should name the certificate holder using its exact legal entity name. A “doing business as” name or trade name can create ambiguity an insurer may exploit during a coverage dispute. If the contract is between your company and “ABC Construction, LLC” but the certificate names “ABC Construction,” the missing “LLC” can become an issue. This matters most with scheduled endorsements, where the insurer only waives subrogation against the specific entity named in the policy.
The text should also mirror the scope of the actual endorsement. For general liability, the standard ISO endorsement is CG 24 04, “Waiver of Transfer of Rights of Recovery Against Others to Us.” For commercial auto, the equivalent is CA 04 44, which modifies the Business Auto Coverage Form, Garage Coverage Form, and Motor Carrier Coverage Form. For workers’ compensation, the endorsement is WC 00 03 13, “Waiver of Our Right to Recover from Others Endorsement.” If your contract requires waivers across multiple coverage lines, each line needs its own endorsement, and the certificate should reflect each one.
Wording That Should Raise Concerns
Watch for a checked SUBR WVD column paired with no waiver language at all in the Description of Operations. Watch also for language saying “waiver of subrogation has been requested” rather than “granted” or “applies.” “Requested” means the endorsement may not actually be on the policy yet. Vague language that names no specific party and references no contract may not provide the protection you need either.
Scheduled Versus Blanket Wording
The two main endorsement structures produce noticeably different certificate wording, and the distinction changes how you read what’s in front of you.
Scheduled Endorsement Wording
A scheduled endorsement names a specific party in the policy itself. The certificate wording typically reads: “Waiver of subrogation is granted to [Specific Company Name] for operations at [Project Address].” This approach is rigid. If the entity name is misspelled, or a related entity is omitted, the waiver may not hold up during a dispute. Insurers prefer scheduled endorsements when they want to control exactly who benefits and for which project.
Blanket Endorsement Wording
A blanket endorsement uses broader language covering any party with whom the insured has a written contract requiring a waiver. The certificate wording typically reads: “Waiver of subrogation applies to all parties where required by written contract executed prior to loss.” The “prior to loss” language is critical. The written contract requiring the waiver must exist before the loss occurs, not after. A blanket endorsement gives contractors and vendors flexibility, because they can issue certificates to new clients without going back to the insurer each time. When reviewing a certificate backed by a blanket endorsement, confirm that your contract with the insured party actually contains a waiver of subrogation requirement. The blanket endorsement only activates for parties whose contracts call for it.
Why the Certificate Alone Does Not Create Coverage
This is the single most misunderstood aspect of certificates of insurance, and misunderstanding it can be expensive. The ACORD 25 contains a disclaimer printed across the top: “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.”
Courts have enforced this disclaimer repeatedly. The actual policy endorsement controls, not whatever the certificate says. If an agent checks the SUBR WVD box or types waiver language into the Description of Operations field but the underlying policy was never endorsed with a waiver, the certificate holder has no waiver protection. The insurer can still pursue subrogation against the certificate holder after paying a claim, and the certificate holder’s only recourse would be against the agent or the party who was supposed to arrange the coverage.
Never treat a certificate as proof you are actually protected. Request a copy of the actual endorsement. The endorsement is a formal amendment to the policy and carries legal weight. The certificate is a summary and carries none.
Waiver of Subrogation Is Not the Same as Additional Insured or Primary and Non-Contributory
Construction contracts and vendor agreements often bundle several insurance requirements together, and the wording on a certificate can blur them. A waiver of subrogation prevents the insurer from suing you to recover money it paid on a claim caused by the insured’s work. Additional insured status puts you on the insured’s policy so you have direct coverage. Primary and non-contributory language ensures the insured’s policy pays first without seeking contribution from your own insurance. These three protections do different things, and having one does not give you the others. If your contract requires all three, the certificate should reflect all three separately.
When the Wording Still May Not Be Enforceable
Even wording that reads correctly can run into state law. Roughly 45 states have anti-indemnity statutes that limit or void certain risk-transfer provisions in construction contracts. Most target broad-form indemnity clauses, but a handful extend to waivers of subrogation and additional insured requirements. Kansas, Louisiana, and New Mexico, for example, have statutes that can nullify waiver of subrogation clauses in certain construction or oilfield contexts. The standard endorsement phrase “to the extent permitted by law” exists precisely because these statutes can override contract terms.
Workers’ compensation waivers face additional scrutiny because state systems are heavily regulated. Some states restrict or prohibit insurers from adding waiver of subrogation endorsements to workers’ compensation policies at all. The rules vary, and a waiver enforceable in one state may be void in the next. Before agreeing to a workers’ compensation waiver in a contract, confirm with your agent that the endorsement is permitted in the state where the work will be performed.
Verifying the Wording Reflects a Real Endorsement
A certificate with the right boxes checked and the right language in the Description of Operations field is a good start, not the finish line. Request a copy of the actual endorsement that was added to the policy. Confirm that the endorsement names you by exact legal name, or that it activates through a blanket provision tied to your written contract. Check that it covers the correct coverage lines. If the other party’s agent cannot or will not provide the endorsement, treat that as a sign the waiver may not actually be in place. A certificate without a backing endorsement is a piece of paper describing coverage that may not exist.
