A waiver of subrogation is an endorsement to a commercial insurance policy that prevents your insurer from suing a third party — typically a client, general contractor, or property owner — to recover losses the insurer already paid on your behalf. It protects business relationships by stopping insurers from pursuing the very parties you contract with. Who this is for: contractors, subcontractors, tenants, vendors, and any business required by contract to add this endorsement.
TL;DR / Key Takeaways
- A waiver of subrogation blocks your insurance company from recovering claim payments by suing the other party named in your contract.
- It is commonly required by general contractors, commercial landlords, and government project owners before work begins.
- The endorsement is typically added to general liability (GL), commercial auto, workers' compensation, and property policies.
- Adding a blanket waiver costs approximately $50–$300 per policy per year for small contractors; larger fleets or payrolls may pay more.
- Failing to add the endorsement when a contract requires it can void contract terms — and potentially leave you personally liable for losses.
What Is Subrogation — and Why Does Waiving It Matter?
Subrogation is the legal right your insurer acquires, after paying your claim, to "step into your shoes" and sue whoever caused the loss. For example: a fire caused by a general contractor's negligence damages your tools stored on a job site. Your property insurer pays you $40,000, then turns around and sues the GC to get that money back. Subrogation protects insurers from absorbing losses that are legally someone else's fault.
A waiver of subrogation eliminates that right. When you add the endorsement, your insurer agrees it will not pursue the named third party — even if that party was at fault. In exchange, you (the policyholder) preserve the working relationship and meet the contractual requirement.
Why Contracts Require It
General contractors, commercial landlords, and government agencies routinely require waivers of subrogation because:
- They want certainty they won't be dragged into a lawsuit by your insurer after a job-site incident.
- They often carry their own insurance and don't want double recovery disputes.
- Standard construction contracts (AIA A201, ConsensusDocs) include mutual waiver language as a default.
Types of Waiver of Subrogation Endorsements
| Type | How It Works | Best For |
|---|---|---|
| Blanket Waiver | Automatically applies to all parties you're contractually required to add | Contractors with many projects / multiple clients |
| Scheduled (Specific) Waiver | Names one party per endorsement; requires a separate filing for each | Businesses with a single or limited number of contracts |
| Mutual Waiver | Both parties waive subrogation against each other | Joint ventures, tenant–landlord relationships |
| Unilateral Waiver | Only one party waives (typically the subcontractor) | Subcontracts under a GC's project |
Recommendation: If you work on multiple projects, a blanket waiver is more efficient and typically costs only slightly more than a scheduled waiver.
Which Policies Can Carry a Waiver of Subrogation?
The endorsement is available on most commercial P&C lines:
| Policy Line | Availability | Notes |
|---|---|---|
| Commercial General Liability (CGL) | Standard | Most common contract requirement |
| Workers' Compensation | Available in most states | Some states restrict or prohibit it — verify with your broker [verify state] |
| Commercial Auto | Available | Often required for fleet contracts |
| Commercial Property | Available | Common in commercial lease agreements |
| Umbrella / Excess Liability | Available | Usually follows the underlying policy's waiver |
| Professional Liability (E&O) | Rarely available | Underwriters often decline; confirm with carrier |
| Builders Risk | Available | Frequently required on construction projects |
How to Add a Waiver of Subrogation in 5 Steps
- Review your contract language. Locate the insurance requirements section. Note whether a blanket or scheduled waiver is required and which policy lines must carry it.
- Contact your broker before signing. Some carriers won't add waivers post-bind or charge a higher mid-term endorsement fee. Confirm availability and cost upfront.
- Request the endorsement in writing. Provide your broker with the project name, contracting party name, and effective date.
- Obtain an updated Certificate of Insurance (COI). The ACORD 25 certificate should include the statement: "Waiver of subrogation in favor of [Party Name] applies with respect to [policy line]."
- Deliver the COI before work begins. Keep a copy in your project file. Some contracts require the waiver to be in place on or before the contract execution date, not just before the first day of work.
Real-World Example: Electrical Subcontractor, Commercial Office Build-Out
Scenario (illustrative — not a guarantee of coverage or outcome):
Bright Line Electric LLC is a licensed electrical subcontractor in Texas with a $1M / $2M commercial general liability policy and a $500,000 workers' compensation policy. They sign a subcontract with Summit Construction (the GC) to wire a 12,000 sq ft office build-out. The subcontract requires:
- A blanket waiver of subrogation on the GL policy in favor of Summit Construction and the project owner.
- A waiver of subrogation on the workers' compensation policy.
During rough-in work, a Bright Line employee is injured when scaffolding collapses — scaffolding owned and erected by Summit. Workers' comp pays $85,000 in medical and lost-wage benefits to the employee. Without the waiver, Bright Line's WC carrier would likely subrogate against Summit (scaffolding was Summit's equipment). Because the waiver was in place, the WC carrier cannot pursue Summit, preserving Bright Line's subcontracting relationship.
Estimated endorsement cost for this scenario: The blanket waiver on GL added roughly $125 to the annual GL premium; the WC waiver cost approximately $200 based on the project's payroll allocation — totaling under $350 for the policy year.
How Much Does a Waiver of Subrogation Cost?
Pricing varies by carrier, policy line, and business size. The figures below are industry-typical ranges for small-to-mid-size commercial accounts:
| Policy Line | Typical Added Cost (Annual) | Notes |
|---|---|---|
| General Liability (Blanket) | $75 – $300 | Flat endorsement fee; some carriers include it |
| Workers' Compensation (Blanket) | $150 – $500 | Often calculated as % of premium or per-project payroll |
| Commercial Property | $50 – $200 | May vary by building value |
| Commercial Auto | $50 – $150 | Per-vehicle or flat endorsement |
Costs shown are illustrative ranges based on typical small commercial accounts. Your actual premium will depend on your carrier, payroll, revenue, loss history, and state of domicile.
FAQ
What is a waiver of subrogation in simple terms?
It's a promise from your insurance company not to sue a third party — usually a client or contractor — after paying your claim, even if that third party was at fault. You agree to this by adding an endorsement to your policy, often because a contract requires it.
Does a waiver of subrogation protect me or the other party?
It protects the other party (the one named in the waiver) from being sued by your insurer. It benefits you indirectly by allowing you to meet contract requirements and maintain business relationships.
Is a waiver of subrogation the same as additional insured status?
No. These are two distinct endorsements often required together. Additional insured status extends your liability coverage to another party. A waiver of subrogation prevents your insurer from suing that party after paying a claim. Both can appear on the same certificate.
Can I add a waiver of subrogation after a claim occurs?
No. The waiver must be in place before the loss occurs. Adding it after the fact has no legal effect on an existing claim. This is why reviewing contract requirements before signing is critical.
Are waivers of subrogation available on workers' compensation in all states?
No. Most states permit them, but a few states restrict or prohibit waivers of subrogation on workers' compensation policies. Confirm availability and any state-specific restrictions with your broker before quoting a contract. [verify state]
What happens if I forget to add the waiver and a claim occurs?
Your insurer may subrogate against the third party, which can damage the business relationship and potentially violate your contract terms — exposing you to breach-of-contract liability. The financial consequence could exceed the cost of the endorsement many times over.
Does a blanket waiver cover all future contracts automatically?
It depends on the endorsement language. A true blanket waiver applies wherever you are contractually obligated to provide one. Read the endorsement carefully — some carriers limit it to named projects or specific policy lines.
Will adding a waiver of subrogation raise my premium significantly?
For most small commercial accounts, the increase is modest — typically under $500 per year across all policy lines. However, if you have high payroll, a large fleet, or significant property values, the cost may be higher. Get a quote before assuming it's included.
