Waiver of Subrogation Explained: What It Means and When Your Contract Requires One
A waiver of subrogation is an agreement that your insurance company will not try to recover what it pays on a claim from a specific other party, usually the client, owner or general contractor you're working for. Contracts require it so a loss on the job is paid by the insurer responsible for it and doesn't turn into a lawsuit between the parties afterward. For most businesses it's added by an endorsement to your business liability insurance, commercial auto and workers' compensation policies.
The waiver has to be in your policy, not just your contract. If you sign a contract promising a waiver and your policy doesn't allow one, you may have just given up your insurer's recovery rights, which can create coverage problems for you.
Below: what subrogation is, why contracts demand a waiver, the endorsements for each line of coverage (including California workers' comp), blanket vs specific waivers, and what to check before you sign.
What subrogation means
Subrogation is the insurer's right to step into your shoes after paying a claim and pursue whoever caused the loss.
A simple example: a delivery driver backs into your storefront. Your commercial property insurance pays to fix it, then goes after the delivery company to get that money back. You get paid quickly, and the cost lands on the party at fault.
Subrogation exists in every major line of business insurance:
Property: the insurer pursues whoever damaged the building or equipment.
General liability: after paying a claim, the insurer pursues another party who contributed to the loss.
Auto: the insurer pursues the at-fault driver or business.
Workers' compensation: after paying an injured employee's benefits, the insurer pursues a third party whose negligence caused the injury.
In California workers' comp, this right is set by statute. Labor Code §3852 preserves an injured employee's claim against third parties and allows an employer who paid compensation to sue the responsible third party to recover it. Insurance Code §11662 subrogates the workers' comp insurer to the employer's rights and lets it enforce them in its own name.
Why contracts require a waiver of subrogation
Picture a commercial remodel. Your employee trips over materials the general contractor left in a hallway. Your workers' comp carrier pays $80,000 in medical and wage-loss benefits. Without a waiver, that carrier can sue the GC to recover the $80,000. The GC then turns to its own insurer, and possibly to the indemnity clause in your subcontract, to push the cost back toward you.
A waiver of subrogation short-circuits that cycle. The parties agree up front that each one's insurance absorbs certain losses without suing the other. Owners, GCs, landlords and large customers want it because:
It keeps them out of lawsuits over losses on their projects or premises.
It protects their loss history and premiums from claims that start under someone else's policy.
It makes risk allocation predictable, especially on projects with many contractors.
It's standard in construction and commercial lease forms, so their legal teams require it by default.
A waiver usually travels with two other requirements: additional insured status and primary and non-contributory wording. Together, they make your insurance respond first and stop your insurer from turning around and pursuing the client.
The endorsements, line by line
Each policy needs its own waiver. A waiver on your general liability does nothing for your workers' comp, and the reverse is true too.
Coverage | Common form | Notes |
General liability | ISO CG 24 04, Waiver of Transfer of Rights of Recovery Against Others to Us | Scheduled. Some carriers include a blanket version in contractor packages. |
Commercial auto | ISO CA 04 44, Waiver of Transfer of Rights of Recovery Against Others to Us | Applies to the business auto policy. |
Workers' comp (California) | Waiver of Our Right to Recover From Others Endorsement – California (WC 04 03 06) | Usually carries an additional premium charge. |
Umbrella / excess | Carrier-specific | Many umbrellas follow the underlying waivers. Confirm with your carrier. |
Property | Policy condition or endorsement | Many commercial property forms permit waivers made in writing before a loss. Check yours. |
General liability: CG 24 04
The CGL policy contains a condition called Transfer of Rights of Recovery Against Others to Us, which is the subrogation clause. CG 24 04 waives that right against the person or organization named in its schedule.
The 2019 revision of CG 24 04 (the 12 19 edition) removed language that had tied the waiver to operations "under a contract with that person or organization." It also conditions the waiver on the named insured having waived its own rights of recovery in writing before the loss. Some carriers use their own forms instead, so read the endorsement you're issued.
Many contractor packages include a blanket waiver for GL that applies to anyone you've agreed in a written contract to waive against. If you have one, you may not need a scheduled CG 24 04 for each job.
Commercial auto: CA 04 44
The business auto form has the same kind of transfer-of-rights condition. CA 04 44 waives it for the parties named in the schedule. The waiver applies when the named insured waived its rights before the accident or loss under a contract with that party. If your contract requires a waiver on auto and you drive to the jobsite, make sure your commercial auto insurance carries it.
California workers' compensation
Workers' comp waivers are the ones most often requested and most often missed. In California, the endorsement is the Waiver of Our Right to Recover From Others Endorsement – California. Under it, the insurer agrees not to enforce its right of recovery against the person or organization named in the schedule. As commonly issued, it applies only to the extent you perform work under a written contract that requires you to obtain this agreement.
Things to know about the California workers' comp waiver:
There is usually a premium charge. The endorsement's schedule states it, typically as a percentage of the California workers' comp premium on the payroll for that work. The percentage and any minimum charge vary by carrier. Ask for the exact charge before you commit to a contract that requires one.
Specific waivers require payroll tracking. For a waiver tied to one job, you may need to keep payroll records showing the remuneration earned on that work, so the charge can be calculated at audit.
Blanket waivers are available from many carriers. They apply to all parties you've agreed in writing to waive, usually at a charge based on your total California premium. If you sign many contracts requiring waivers, a blanket is usually simpler.
A related California rule: under Labor Code §3864, if an injured employee (or the employer) recovers from a third party, the employer has no liability to reimburse or hold that third party harmless unless there's a written agreement to do so executed before the injury. That's why owners and GCs insist on these terms in writing and up front. For more on how comp works in California, see our guide to workers' comp in California.

Blanket vs specific waivers
| Specific (scheduled) | Blanket |
Who is covered | Only the parties named in the endorsement's schedule | Anyone you've agreed in a written contract to waive against |
Best for | Occasional contracts, one large project | Contractors and vendors who sign many contracts |
Admin | New endorsement for each request; risk of gaps if you forget | Set once at policy issue; still needs a written contract before the loss |
Cost (workers' comp) | Charge based on payroll for that job | Charge based on total California premium |
Common trap | Contract signed, endorsement never requested | Assuming "blanket" covers parties you agreed to verbally |
Both versions depend on the written contract existing before the loss. If you start work on a handshake and sign the paperwork after someone is hurt, the waiver may not apply.
The risk of signing a waiver your policy doesn't allow
This is the part that costs businesses money.
Most liability, auto and property policies let you waive recovery rights in writing before a loss. That's why the CGL transfer-of-rights condition says the insured must do nothing after a loss to impair those rights. But not every policy, and especially not every workers' comp policy, automatically allows a waiver without an endorsement.
If you sign a contract promising a waiver of subrogation and your policy doesn't contain or permit one:
You may be in breach of the contract. The client can treat the missing waiver as a breach. That can mean withheld payments, termination or a damages claim if they end up paying a loss they expected your insurer to absorb.
You may have impaired your insurer's rights. If your policy requires you to preserve the insurer's recovery rights and you gave them away without permission, your insurer may have grounds to dispute part of the claim.
Your certificate may misstate your coverage. If your agent checks "SUBR WVD" on your certificate without an endorsement behind it, everyone is relying on something that doesn't exist. The ACORD 25 itself notes that when subrogation is waived, "certain policies may require an endorsement," and that a statement on the certificate doesn't take the place of one.
The fix is simple: send the insurance section of every contract to your agent before you sign. Confirm which waivers are already in your policies, which need an endorsement, and what each will cost. Then make sure the certificate reflects the endorsements you actually have. Our certificate of insurance request template includes the request language for both sides.
How a waiver shows up on a certificate of insurance
On the ACORD 25, each policy line has a SUBR WVD column. A "Y" there means the agent is reporting a waiver on that policy. The details usually appear in the Description of Operations box, for example: "Waiver of subrogation applies in favor of [Owner] on GL, auto and workers' compensation per written contract."
If you're the client receiving the certificate, ask for a copy of each waiver endorsement, just as you would for additional insured status. Our guide on how to read a certificate of insurance walks through the form.
Common waiver mistakes
Requesting GL only. Many contracts require the waiver on GL, auto and workers' comp. Missing one is a common audit finding on construction projects.
Forgetting the umbrella. If the contract requires waivers on all policies, confirm the umbrella follows form.
Not budgeting the workers' comp charge. On a high-payroll job, the waiver charge can be meaningful. Build it into your bid.
Waiving more than the contract requires. A blanket waiver typically applies only where you've agreed in writing. Don't sign side agreements waiving rights against parties the main contract doesn't require.
Letting it lapse at renewal. A new policy period, or a new carrier, may not carry the endorsement forward unless you ask.
If you're a contractor juggling multiple GCs, these requirements are routine. Our contractors insurance programs are set up with them in mind.
FAQs
What does waiver of subrogation mean in simple terms?
It means your insurance company agrees not to sue a specific party, usually your client, to recover money it paid on your claim. The loss stays with your insurer instead of becoming a dispute between you and the client.
Who benefits from a waiver of subrogation?
The party named in the waiver, typically the owner, general contractor, landlord or customer who required it. They're protected from being pursued by your insurer after a covered loss.
Does a waiver of subrogation cost extra?
Often on workers' comp, where California carriers usually add a charge stated on the endorsement as a percentage of premium. On general liability and auto, it's frequently included in contractor packages or available for a small charge, depending on the carrier.
What is a blanket waiver of subrogation?
An endorsement that applies the waiver automatically to anyone you've agreed in a written contract to waive against, so you don't need a separate endorsement for each client. The written agreement still has to exist before the loss.
Can I sign a contract with a waiver of subrogation if my policy doesn't have one?
You can sign it, but you may be in breach of the contract and could create a coverage problem with your insurer. Ask your agent to add the endorsement, or confirm your policy already permits the waiver, before you sign.
Is a waiver of subrogation the same as additional insured status?
No. Additional insured status gives the client rights under your policy. A waiver of subrogation stops your insurer from pursuing the client. Contracts usually require both, plus primary and non-contributory wording.
