Waiver of Subrogation: What It Is and Why Your Contract Requires It

Buried in the insurance section of almost every commercial contract is a line requiring a waiver of subrogation in favor of the other party. It sounds technical, and it's easy to sign past — but it changes who can be chased for a loss after the dust settles. Here's what it actually does.

First, what subrogation is

When your insurer pays a claim, it generally gains the right to "step into your shoes" and recover that money from whoever actually caused the loss. That's subrogation. If your carrier pays for damage that a third party was responsible for, it can then pursue that third party to get its payment back. The point is to keep the ultimate cost of a loss with the at-fault party instead of the insurance company — and, in theory, to keep everyone's premiums lower.

What a waiver of subrogation does

A waiver of subrogation gives up that recovery right against a specific, named party — and it's almost always agreed to before any loss, because a contract demands it.

Here's the construction example. A general contractor requires each subcontractor's policy to carry a waiver of subrogation naming the GC (and often the owner). Now if the sub's insurer pays a claim — even one the GC was partly responsible for — it has waived its right to turn around and sue the GC to recover that payment. The GC is protected from being chased by its subs' insurers. That's the entire purpose: it stops the finger-pointing and cross-litigation that would otherwise follow a shared loss.

It matters to the party requiring it because without the waiver, they could "win" a project with no claims of their own and still get sued months later by a subcontractor's insurance company.

The GL form vs. the workers' comp form

A waiver isn't a single document — it's endorsed onto each policy the contract names:

• General liability — the common ISO form is CG 24 04, *Waiver of Transfer of Rights of Recovery Against Others to Us*. It waives the GL insurer's recovery rights against the party named in the endorsement's schedule.
• Workers' compensation — the WC policy has its own waiver endorsement (the ISO/NCCI *Waiver of Our Right to Recover From Others*), and it behaves a little differently: a workers' comp waiver usually carries an additional premium charge, because the carrier is giving up a real recovery right against a third party who injured the employee. WC waivers can be blanket (covering anyone the insured is required by contract to waive) or scheduled (naming specific parties).

If a contract requires a waiver "on all policies," that means the GL *and* the workers' comp waiver — and often the auto and umbrella as well. Each has to be endorsed separately.

Blanket vs. scheduled

Like additional insured endorsements, waivers come in two flavors:

• Scheduled — names the specific party being waived.
• Blanket — waives subrogation against anyone the insured is required by written contract to waive, without naming them. Convenient for a contractor with many jobs, but it only applies where a written contract actually requires the waiver.

The certificate trap

This is where businesses get caught: a certificate of insurance will often show "waiver of subrogation applies," but the certificate doesn't create the waiver — only the endorsement on the policy does. A common and costly misunderstanding is assuming the certificate proves the waiver exists when the endorsement was never actually issued. Always confirm the endorsement is attached, with the right party named and an edition that matches the contract.

How it fits with the other two requirements

Waiver of subrogation almost never travels alone. It's one leg of the standard three-part risk-transfer package in commercial contracts:

• Additional insured — adds the other party to your policy as an insured
• Primary and non-contributory — makes your policy pay first, without seeking contribution
• Waiver of subrogation — stops your insurer from recovering from that party after it pays

They address three different questions, and a contract commonly requires all three. Critically, one does not satisfy the others — each needs its own endorsement, correctly named and in force. This is the same contract-and-coverage alignment problem we cover in contractual liability and business insurance for contractors.

Our approach

At Cory Washington & Co., we read the insurance requirements in your contracts and make sure the waivers they demand are actually endorsed onto the right policies — the GL waiver, the workers' comp waiver (and we flag the premium charge that comes with it), and auto or umbrella where required — with the correct parties named and editions that match the contract. And we line it up alongside the additional insured and primary and non-contributory requirements so all three are in force, not just shown on a certificate.
