A waiver of subrogation is an endorsement on a commercial insurance policy in which the insurer gives up the right to sue a third party — typically a general contractor, property owner, or client — to recover money it paid on a claim. If your contract requires one, your insurer must agree before a loss occurs. Who this is for: contractors, subcontractors, tenants, vendors, and any business that signs commercial agreements requiring proof of the waiver.
TL;DR — Key Takeaways
- A waiver of subrogation stops your insurer from suing the party you named in your contract after paying your claim.
- It must be added by endorsement before the loss happens — you cannot waive subrogation rights retroactively in most states.
- It is most commonly required on general liability, workers' compensation, and commercial property policies.
- The endorsement adds cost (typically $50–$350 per policy per year for straightforward trade contractor accounts, but it varies by insurer and exposure).
- Failing to get the endorsement when a contract requires it can void the contractual protection you thought you had and expose you to breach-of-contract claims.
What Does "Subrogation" Mean in Insurance?
Subrogation is the legal process by which an insurance company steps into the shoes of its insured to recover damages from a third party that caused — or contributed to — the loss. Suppose your commercial property insurer pays $80,000 to rebuild your equipment after a sprinkler contractor left a valve open. Without a waiver of subrogation, your insurer can sue that contractor to recoup the $80,000. With a properly endorsed waiver of subrogation, that right is surrendered — the insurer cannot pursue the contractor, and the contractor's own insurer is protected as well.
Why Do Contracts Require It?
General contractors, property owners, and large clients include waiver of subrogation clauses in their master service agreements, lease agreements, and subcontracts because they want certainty: if a loss occurs, their insurance carrier will not be dragged into cross-claims and litigation by your carrier. It keeps projects moving and legal exposure contained.
Which Policies Can Carry a Waiver of Subrogation?
| Policy Type | Typical Waiver Form | When It's Required |
|---|---|---|
| Commercial General Liability (CGL) | CG 24 04 or equivalent endorsement | Subcontracts, vendor agreements, leases |
| Workers' Compensation | WC 00 03 13 (NCCI) or state equivalent | Construction contracts; some state public works |
| Commercial Property (Building / BPP) | Endorsement varies by insurer | Lease agreements, property management contracts |
| Commercial Auto | Endorsement varies | Fleet leases, transportation agreements |
| Umbrella / Excess | Follows form from underlying | When underlying policies carry the waiver |
Note: On workers' compensation policies, the waiver endorsement is particularly common in construction. The NCCI WC 00 03 13 form ("Waiver of Our Right to Recover from Others Endorsement") is used in most states that follow NCCI; monopolistic state fund states (Ohio, North Dakota, Washington, Wyoming) handle waivers differently — [verify state] before assuming the endorsement is available.
How to Add a Waiver of Subrogation: A 5-Step Process
- Read your contract. Identify the exact party to be named in the waiver (e.g., "ABC General Contractors and its subsidiaries"). Some contracts require a blanket waiver of subrogation; others require a scheduled (named) waiver.
- Contact your broker or agent before you sign the contract. Your insurer's consent is typically required in advance of any loss. Many policies contain language voiding the waiver if it is agreed to only after a claim.
- Request the endorsement. Your agent submits the request to the insurer. Provide the contract language and the name of the entity to be covered.
- Review the endorsement wording. Confirm the named party matches the contract requirement exactly — "ABC General Contractors, LLC" is not the same as "ABC General Contractors, Inc."
- Issue an updated certificate of insurance (COI). The certificate must reflect the waiver of subrogation in the Description of Operations or via ACORD 25 checkboxes. Provide the updated COI to the party that required it.
Blanket vs. Scheduled Waiver of Subrogation
Many insurers now offer a blanket waiver of subrogation endorsement, which automatically applies to any party where a written contract requires the waiver — without needing to name each party individually. This is the preferred option for contractors with many active subcontracts or vendor agreements.
A scheduled waiver names specific entities and is more restrictive. If you add a new client mid-term and your policy only has a scheduled waiver, you must endorse the policy again before that new contract is covered.
| Feature | Blanket Waiver | Scheduled Waiver |
|---|---|---|
| Parties covered | Any party per written contract | Named parties only |
| Administrative burden | Low — one endorsement covers all | High — update each new party |
| Cost | Slightly higher flat charge | May be lower if few parties |
| Best for | Contractors with multiple clients | One or two key relationships |
How Much Does a Waiver of Subrogation Cost?
Cost depends on the policy type, insurer, and your payroll or revenue base. The following ranges are illustrative for small to mid-size commercial accounts — they are not guarantees.
| Policy | Typical Additional Premium | Notes |
|---|---|---|
| General Liability (blanket) | $75 – $250/year | Some insurers include it at no extra charge on CGL |
| Workers' Compensation | $50 – $350/year | NCCI states may charge a flat fee or a % of premium (often 2–5%) |
| Commercial Property | $0 – $150/year | Often included or minimal charge on commercial property |
| Commercial Auto | $50 – $200/year | Flat endorsement fee; varies by fleet size |
Costs are illustrative examples based on typical market ranges as of 2026. Your actual premium will depend on your insurer, state, payroll/revenue, and policy terms.
Real-World Example: Electrical Subcontractor in Texas
Scenario (illustrative — not a guarantee of any specific outcome):
A Texas-based electrical subcontractor — call them Volt Electric LLC — signs a subcontract with a general contractor, SunState Construction, to wire three commercial buildings. The subcontract requires Volt to carry:
- $1M / $2M commercial general liability with a blanket waiver of subrogation in favor of SunState Construction and the project owner
- Workers' compensation with a waiver of subrogation per Texas rules
During installation, a Volt employee accidentally damages a water line, causing $95,000 in flood damage to an adjacent tenant's finished space. Volt's CGL insurer pays the claim. Because Volt's policy carries the blanket waiver of subrogation endorsement naming SunState Construction, the insurer cannot pursue SunState for any portion of the $95,000 — even if SunState's site supervision contributed to the incident. The dispute stays between Volt's insurer and the claim, and the project continues without cross-party litigation.
Without the endorsement: Volt's insurer might have subrogated against SunState's insurer for its share of fault, triggering legal defense costs for SunState and potentially jeopardizing Volt's relationship with the GC.
Cost of the endorsement for Volt: approximately $175 added to the CGL annual premium and $120 added to workers' comp — roughly $295/year for the coverage certainty that kept a $95,000 claim from spawning a lawsuit.
FAQ — Waiver of Subrogation
Q: Is a waiver of subrogation the same as an additional insured? No. These are two different endorsements that serve different purposes and are often required together. An additional insured endorsement gives a third party direct coverage rights under your policy (they can make a claim against it). A waiver of subrogation endorsement restricts your insurer's right to sue that third party after paying a claim. A contract may require both.
Q: Can I add a waiver of subrogation after a loss has already occurred? Generally, no. Most policies and state courts hold that subrogation rights vest at the time of loss. Agreeing to waive them after a claim has been reported — or after you are aware a loss is imminent — will typically not be honored by the insurer and could be considered a breach of the policy conditions. Always secure the endorsement before you sign the contract.
Q: Does a waiver of subrogation protect me if I'm negligent? Not exactly. The waiver protects the named third party from being sued by your insurer to recover what it paid. It does not shield you from liability in general. If the third party suffers a loss that is not covered by your policy, they may still have a direct claim against you. The waiver only affects the insurer's recovery rights.
Q: What is a "blanket" waiver of subrogation and do I need one? A blanket waiver automatically extends to any party where a written contract requires it — you do not need to name each party individually. If you work with multiple general contractors, owners, or clients who each require this in their contracts, a blanket waiver is far more practical and typically only costs slightly more than a scheduled waiver.
Q: Do workers' compensation policies need a separate waiver of subrogation from my general liability policy? Yes. Waiver of subrogation endorsements are policy-specific. If your contract requires waivers on both your CGL and your workers' comp policy, each policy must carry its own endorsement. Your certificate of insurance (ACORD 25) will reflect the waiver separately for each line of coverage.
Q: Will my insurer always agree to add the waiver? Most standard commercial insurers will endorse the waiver for routine commercial relationships. However, some insurers restrict blanket waivers for high-hazard classes or require underwriter approval. If a carrier refuses, your broker should be able to market your account to a carrier that will accommodate the requirement.
Q: Does the waiver of subrogation appear on my certificate of insurance? Yes. When a waiver of subrogation endorsement is active, it should be reflected in the "Description of Operations" box on your ACORD 25 certificate. The party requiring the waiver will typically look for this language before allowing work to proceed or releasing a contract payment.
Q: What happens if I forgot to add the waiver before signing a contract? Contact your broker immediately and request the endorsement. If no loss has occurred, your insurer can add it retroactively to the contract start date in many cases — but this is not guaranteed and depends on the insurer's appetite and state regulations. Waiting until a claim happens is too late.
