Subrogation is the right of an insurance company, after paying a claim, to step into the insured's shoes and sue whoever caused the loss to recover what it paid. A Waiver of Subrogation is a contractual promise — backed by a policy endorsement — that the insurer will not exercise that right against a specific third party.
In commercial vendor contracts, Waiver of Subrogation is second only to Additional Insured in how often it appears. Property managers, general contractors, landlords, and enterprise clients all require it. Workers' Compensation Waivers of Subrogation are especially common because they protect the client from being sued by the vendor's own workers' comp carrier after an injury on the client's property.
This guide explains what Waiver of Subrogation does, where it shows up on a COI, the endorsement forms that grant it, and the specific patterns compliance teams should verify before approving a certificate.
What Subrogation Actually Is
When an insurer pays a claim, the law lets it pursue the party that caused the loss. A vendor's employee is injured on a property manager's site because of a defect in the building. The vendor's Workers' Comp carrier pays the medical bills and lost wages. Subrogation lets that carrier turn around and sue the property manager for reimbursement.
A Waiver of Subrogation is the vendor's contractual promise that its insurer will not do that — and the corresponding endorsement on the vendor's policy that binds the insurer to the waiver. Without the endorsement, a purely contractual waiver may not stop the insurer from proceeding.
Why Clients Require It
The economic reason is simple: a client that hires vendors does not want to be sued by those vendors' insurance carriers after a claim. A property manager with a hundred vendors on-site every year does not want to face a hundred potential subrogation actions.
The legal reason is that many contracts already contain broad indemnification clauses in favor of the client. A Waiver of Subrogation reinforces indemnification by ensuring the vendor's insurer cannot end-run the indemnity by suing the client after paying the vendor's claim.
How It Appears on a COI
There is no dedicated checkbox for Waiver of Subrogation on a standard ACORD 25 certificate. It typically appears in the Description of Operations box: "Waiver of Subrogation applies in favor of [Client Name] with respect to General Liability, Auto Liability, and Workers' Compensation per attached endorsement."
Endorsement forms that grant the waiver vary by carrier and line of coverage. On Workers' Comp, WC 00 03 13 is the standard form. On General Liability, CG 24 04 is the ISO form. Auto Liability often uses CA 04 44. Sophisticated compliance teams request copies of these endorsements for high-value contracts.
“Contractor and its insurers waive all rights of subrogation against Owner, its officers, directors, employees, agents, and affiliates for all losses covered under Contractor's Commercial General Liability, Automobile Liability, Workers' Compensation, and Umbrella policies.”
Waiver of Subrogation on Workers' Compensation
This is the most heavily requested — and most heavily audited — variant. Workers' Comp is no-fault: if a vendor's employee is injured on a client's premises, the vendor's WC carrier pays the claim regardless of who was at fault. Without a waiver, that carrier can then sue the client for causing the injury.
Nearly every commercial property, construction, industrial, and enterprise contract requires WC Waiver of Subrogation. Many states charge a small premium for the endorsement (often 2%–5% of the WC premium). Some states restrict blanket waivers and require scheduled endorsements naming the specific entity. Brokers should confirm the state rules before promising the endorsement.
Common Mistakes
- Contract requires WC Waiver of Subrogation but the vendor's certificate only shows GL Waiver.
- The wording on the COI grants a waiver "where required by written contract" — technically valid but not always accepted by strict compliance reviewers who want a scheduled endorsement.
- The endorsement names the wrong entity (property manager instead of property owner, or vice versa).
- Waiver granted only to "the certificate holder" when the contract requires the waiver to also extend to affiliates, parents, and subsidiaries.
- State law restrictions (particularly in Missouri, Texas, and Ohio's monopolistic WC state) that limit or complicate WC waivers.
Best Practices
For vendors: ask your broker to add Waiver of Subrogation endorsements on GL, Auto, WC, and Umbrella at policy inception, and keep endorsement copies with your COI package. Blanket waiver endorsements (WC 00 03 13A) that automatically waive rights against any party you have agreed in writing to waive against are widely accepted and save time.
For brokers: read the contract's waiver clause and confirm which policies must carry the endorsement. Confirm the state permits the requested waiver. Reference the endorsement form number in the COI Description of Operations so compliance reviewers can verify it.
For compliance teams: check that every policy the contract lists — not just GL — carries the waiver. For high-risk contracts, request the actual endorsement forms and verify the named entities.
Realistic clause examples
Representative wording from commercial vendor agreements. Use as reference only — actual contract language varies by counterparty, industry, and jurisdiction.
“Contractor and its insurers waive all rights of subrogation against Owner, its officers, directors, employees, agents, and affiliates for all losses covered under Contractor's Commercial General Liability, Automobile Liability, Workers' Compensation, and Umbrella policies.”
Frequent compliance errors to avoid

Waiver of Subrogation extraction and verification
CoverageReady scans contracts for the specific phrases that trigger Waiver of Subrogation requirements — "waive rights of subrogation," "waiver of subrogation," "in favor of Owner," "pursuant to WC 00 03 13" — and captures both the required scope (which policies) and the entities to be protected.
On the COI side, CoverageReady parses the Description of Operations text for waiver references, per-policy indicators, and endorsement form numbers. It checks that a waiver granted only on General Liability is not treated as satisfying a contractual requirement for Workers' Comp waiver, and vice versa. When a required waiver is missing from a specific line of coverage, the gap is flagged with a citation back to the contract clause and an explanation of which endorsement form typically resolves it.
For Workers' Comp waivers in states with special rules, the system surfaces the jurisdictional context so brokers can review before certifying compliance rather than being surprised at renewal.
CoverageReady scans for the specific trigger phrases, endorsement form numbers, and entity references that indicate this requirement, capturing the exact clause and location within the contract.
Every extracted requirement links back to the highlighted clause in the source contract, so reviewers can verify the AI's interpretation without re-reading the full document.

Frequently asked questions
Is Waiver of Subrogation the same as Additional Insured?
No. Additional Insured gives the client coverage under the vendor's policy. Waiver of Subrogation prevents the vendor's insurer from suing the client after paying a claim. Most contracts require both because they solve different problems.
Do I need Waiver of Subrogation on Workers' Compensation?
If the contract requires it — yes, and almost every commercial contract does. Workers' Comp waivers protect the client from being sued by the vendor's WC carrier when a vendor employee is injured on-site.
Is there a cost?
Waiver endorsements on GL, Auto, and Umbrella are typically included or nominal. WC waivers usually carry a small premium charge that varies by state (often 2%–5% of WC premium).
Will a blanket Waiver of Subrogation satisfy the contract?
Usually yes, if the wording is broad enough to cover "any person or organization the named insured has agreed in a written contract to waive rights of subrogation against." Some compliance programs prefer scheduled endorsements naming the specific entity; check the contract.
Waiver of Subrogation is a vendor's contractual promise, backed by a policy endorsement, that its insurer will not pursue the client for reimbursement after paying a claim.
