Waiver of Subrogation on a COI: What It Means
The CertifiKit team
Certificate-of-insurance desk
A waiver of subrogation limits an insurer's ability to recover a claim payment from another party, to the extent the applicable policy wording provides. A certificate of insurance may report that a waiver exists, but the certificate does not create the waiver. Review the relevant policy or endorsement and its conditions.
For someone collecting vendor certificates, the practical question is not just “Does the COI say waiver?” It is “Which policy, party, and work does the supporting wording address?”
What is subrogation?
Subrogation allows an insurer to pursue recovery from a third party responsible for a loss. The Hartford's insurance glossary explains that underlying right.
A waiver changes the recovery position where its terms apply. It is not a promise that every loss will be insured or that nobody can bring a lawsuit.
Are a waiver of subrogation and a certificate of insurance the same thing?
No. A certificate of insurance summarizes reported coverage. A waiver addresses recovery rights under the applicable insurance arrangements. You can receive a certificate without receiving evidence of a required waiver.
| Document or requirement | What you are reviewing | What to ask next |
|---|---|---|
| Certificate of insurance | Reported policies, limits, dates, and indicators | Does this match the documents requested? |
| Waiver wording or endorsement | The recovery rights being waived and applicable conditions | Which parties, work, and policy does it address? |
| Additional insured wording | Whether another party has insured status under the policy | Does its scope match the requirement? |
ACORD explains that a certificate does not amend the policy in its certificate FAQ. For the broader document workflow, see what a COI is and how it works.
Where is waiver of subrogation shown on an ACORD 25?
Look at the SUBR WVD column on the relevant coverage row and the description of operations. A form number or wording in that description can help identify the supporting document to request.
Record each policy separately. A waiver indicator on the general liability row does not resolve a requirement concerning workers' compensation. The ACORD 25 walkthrough shows how to trace policy rows and insurer letters.
The Texas Department of Insurance's certificate FAQ explains waiver indicators and the treatment of blanket endorsements under Texas rules. Do not assume those instructions determine the treatment of every policy in every state.
Does a waiver always require a separate endorsement?
No. The applicable wording may already be included in the policy or added through an endorsement. For example, The Hartford's business-auto guide describes a waiver provision tied to a written contract that avoids separately endorsing that particular policy for the request. That example does not establish the terms of your vendor's policy.
Ask the producer for the actual supporting wording. Do not reject an explanation solely because it uses a different form number from a generic checklist.
What is the difference between scheduled and blanket waivers?
A scheduled waiver identifies the relevant party in a schedule. A blanket provision describes when the waiver applies to a class of parties, often by reference to a written agreement. The exact form, edition, and conditions control; the labels alone do not answer whether your situation qualifies.
Use these questions when requesting clarification:
- Which policy contains the waiver?
- Is the relevant organization specifically listed, or does it need to satisfy a condition?
- Does the wording require a written contract or agreement?
- Does it specify when that agreement must have been made?
- Does it limit the waiver to particular work or operations?
Do not apply one universal pre-loss contract rule to every scheduled and blanket form. Read the actual wording and ask your insurance professional to interpret it.
Example: a certificate says “waiver applies”
This is a fictional document-review example. A maintenance vendor sends a certificate with SUBR WVD marked for general liability. Your request also asks for waiver evidence for another policy, but no supporting documents are attached.
A useful review record would say:
- General liability waiver indicator recorded.
- Supporting general liability wording requested.
- Separate waiver requirement for the other policy remains unresolved.
- Producer asked to identify the parties and work addressed by each provision.
The reviewer has identified what is missing. They should not conclude that the waiver is absent from the policy, or that the entire submission meets requirements, solely from the certificate.
Waiver of subrogation vs. additional insured
A waiver addresses recovery rights. Additional insured status concerns coverage under another party's policy. One does not establish the other, and neither makes every possible claim payable.
Track the two requirements separately. Our certificate holder vs. additional insured guide explains why merely putting an organization's name on a certificate is a different step from resolving insured status.
How much does a waiver of subrogation cost?
Ask the producer for a quote for the specific policy and request. A waiver may already be included; a change may instead require an endorsement and a charge. Do not apply a general percentage or dollar minimum to every insurer, state, or line of coverage.
Ask whether the quote is for the waiver, an additional insured change, another coverage change, or document service. Those are different requests. The cost of obtaining a certificate itself is discussed in our COI basics guide.
What should I ask the vendor's producer for?
Adapt this to your written requirements:
The certificate for [vendor/project] reports a waiver of subrogation on [policy line]. Please provide the policy provision or endorsement supporting that statement, including the applicable form edition and schedule. Please identify the parties, work, and any written-agreement conditions it addresses, and clarify the outstanding requirement for [other policy line, if applicable].
Keep the reply with the certificate and review notes. For renewals, check whether the policy identifiers or supplied documents have changed before carrying the previous review forward.
Can a COI checker verify the waiver?
The free COI checker reads reported waiver signals and compares the certificate with your selected requirements. It helps identify questions and missing evidence. A certificate-only check cannot establish all the terms of a waiver or determine whether it will apply to a loss.
