What Is a Waiver of Subrogation? A Plain-English Guide
Subrogation is a concept most people never encounter until it shows up in a claim. A waiver of subrogation, meanwhile, is one of the most commonly required items on a certificate of insurance -- and one of the least understood.
This guide explains what subrogation is, what a waiver of subrogation does, why property managers and contractors need to require it, and how to verify it on a COI.
What Is Subrogation?
Subrogation is a legal right that allows an insurance company to step into the shoes of its insured and pursue recovery from a third party who caused a covered loss.
Here is how it works in practice:
A vendor's employee is injured while working at your property. The injury was partly caused by a condition on your premises. The vendor's workers' compensation insurer pays the employee's medical expenses and lost wages -- as required by the policy.
Now, the insurer believes your organization contributed to the injury. Under the right of subrogation, the insurer can sue your organization to recover the amount it paid to the employee. The employee has already been compensated. Now it is the insurer versus you.
This is not a theoretical risk. Workers' compensation insurers routinely exercise subrogation rights against third parties who contribute to worker injuries. For property management companies with many vendors working on-site, this creates a recurring exposure.
What Does a Waiver of Subrogation Do?
A waiver of subrogation is an endorsement to an insurance policy -- most commonly a workers' compensation policy, but also applicable to general liability and commercial auto -- in which the insurer agrees to give up its right to pursue subrogation against a specified party.
When a vendor obtains a waiver of subrogation in favor of your organization, their insurer cannot come after you even if you contributed to a covered loss. The insurer pays the claim and that is the end of it, as far as your organization is concerned.
This is why waivers of subrogation are a standard requirement in vendor contracts and COI compliance programs across property management.
Types of Waiver of Subrogation
Per-Contract (Specific) Waiver
A specific waiver names the party in whose favor the waiver applies -- your property management company, for example. The insurer agrees not to pursue subrogation specifically against the named party.
This type of waiver requires the vendor to have the endorsement added to their policy for each contract relationship where a waiver is required. It is the most precise form but also requires active management.
Blanket Waiver of Subrogation
A blanket waiver applies automatically to any party the named insured has agreed by written contract to provide a waiver. When a vendor's policy includes a blanket waiver and their contract with you requires a waiver, the waiver automatically applies to your relationship without requiring a separate endorsement for each contract.
Blanket waivers are more common in commercial policies today and are generally acceptable, but verify that the blanket language is actually included in the vendor's policy (not just claimed on the COI) and that no exclusions apply to your type of organization or property.
When to Require a Waiver of Subrogation
Workers' Compensation: Always
For any vendor with W-2 employees working on your properties, require a workers' compensation waiver of subrogation as a non-negotiable condition. Workers' compensation subrogation claims against property owners and managers are common. The waiver is standard practice and should not be a point of negotiation with any legitimate vendor.
General Liability: For High-Risk Vendors
For general contractors, roofers, and other high-risk trades, require a waiver of subrogation on the general liability policy as well. This prevents the vendor's insurer from pursuing you for property damage or bodily injury claims that the insurer paid to third parties.
Commercial Auto: Where Applicable
If vehicle accidents on your property or access roads create exposure, requiring a commercial auto waiver of subrogation may be appropriate for vendors who operate vehicles as part of their work.
How to Verify a Waiver of Subrogation on a COI
On an ACORD 25 form, the waiver of subrogation is indicated by a checkbox column to the right of each coverage line. The column header is typically "WVR" or "Waiver of Subrogation."
For workers' compensation, the checkbox should be marked, and your entity's name (or "blanket" language) should appear in the description of operations.
Verification Levels
Level 1: Checkbox marked on the workers' compensation line plus reference in the description of operations. Minimum acceptable for most vendor relationships.
Level 2: Endorsement page from the policy documenting the waiver language and naming your entity (or confirming blanket language). Required for Tier 1 vendors.
Level 3: Direct carrier confirmation that the waiver is in force and applies to your organization. Appropriate for high-value contracts or situations where the vendor's carrier is unfamiliar.
Red Flags
- Waiver checkbox marked but no supporting language in the description of operations
- Description of operations refers to a specific project address when the vendor works across multiple properties
- Blanket waiver language that excludes certain types of property owners (some policies exclude government entities, for example)
- No waiver at all -- a common deficiency in COIs submitted by smaller vendors who were not instructed by their broker to include it
Cost and Availability
Most commercial insurance carriers include blanket waiver of subrogation provisions in their standard workers' compensation and commercial general liability policies at little or no additional premium. For vendors who claim that adding a waiver requires an additional charge, the amounts are typically small (often $50 to $200 per year for the endorsement). A vendor who is unwilling to pay a modest endorsement fee for your requirement is a vendor worth reconsidering.
Some policies do not permit waivers of subrogation in certain circumstances -- typically where the waiver would conflict with other policy provisions or applicable law. If a vendor's carrier genuinely cannot add the endorsement, have the vendor's broker provide a written explanation and consult your risk advisor about acceptable alternatives.
Waiver of Subrogation vs. Additional Insured: The Difference
These two endorsement requirements are frequently confused because they appear on the same COI. They serve different purposes:
Additional insured endorsement gives you the right to make a direct claim under the vendor's policy for losses arising from the vendor's operations.
Waiver of subrogation prevents the vendor's insurer from suing you after paying a claim -- regardless of whether you are an additional insured.
You need both. Additional insured status lets you access the vendor's coverage. Waiver of subrogation protects you from the insurer's recovery actions after a claim.

Key Takeaways
- Subrogation is the insurer's right to sue third parties who contributed to a covered loss.
- A waiver of subrogation eliminates this risk by having the insurer agree in advance not to pursue you.
- Require waivers of subrogation on workers' compensation for all vendors with employees.
- Blanket waivers are acceptable if properly documented; verify the endorsement exists.
- Waiver of subrogation and additional insured status are separate protections that work together.
Frequently Asked Questions
What happens if I do not require a waiver of subrogation?
Without a waiver, the vendor's insurer retains the right to pursue subrogation against your organization after paying a covered claim. If a worker is injured at your property and your organization contributed to the injury (a slippery walkway, inadequate lighting, a hazard you failed to address), you may face a subrogation claim from the worker's insurer even after the worker has been compensated.
Can a vendor's insurer pursue subrogation if I am listed as an additional insured?
Yes, in some cases. Additional insured status and waiver of subrogation are different protections. Additional insured status covers you for third-party claims. Subrogation involves the insurer's own recovery rights. Some policy forms limit subrogation against additional insureds, but the safest approach is to require both the additional insured endorsement and the waiver of subrogation explicitly.
Is a blanket waiver of subrogation as effective as a specific waiver?
Generally yes, provided the blanket waiver language in the policy applies to your specific relationship and no exclusions apply. The key is to confirm that the blanket waiver is actually in the policy (not just checked on the COI) and that your contract with the vendor includes a written requirement for a waiver, which is what typically triggers the blanket provision.
Do I need a waiver of subrogation from sole proprietors?
Sole proprietors in most states can opt out of workers' compensation for themselves and may have no employees. If a sole proprietor has no workers' compensation policy, there is no waiver to obtain. Document their workers' compensation status in writing. If they subcontract to individuals, those individuals may be employees -- confirm coverage status for anyone performing work.
