Waiver of Subrogation, Explained for General Contractors

What Subrogation Means

When an insurance company pays a claim, it generally has the right to "step into the shoes" of the party it just paid and go after whoever actually caused the loss, to recover what it paid out. That right is called subrogation. On a construction jobsite with a GC, multiple subcontractors, and property owners all working around each other, subrogation creates a real risk: your own insurer, after paying your claim, could turn around and sue a subcontractor to recover the money — even if that sub is someone you have an ongoing working relationship with, and even if the whole situation was accepted as a normal jobsite risk by everyone involved.

What a Waiver of Subrogation Does

A waiver of subrogation is language — either in the contract, the insurance policy, or both — where each party's insurer agrees to give up that right to sue the other party after paying a claim. In effect, everyone agrees up front: if something goes wrong and my insurance pays for it, my insurer won't turn around and come after you for it. This keeps jobsite relationships intact, avoids insurers fighting each other, and creates predictability — everyone knows going in that their own coverage is expected to absorb certain losses without a fight over who ultimately pays.

Why GCs Require It From Subcontractors

Without a waiver of subrogation, a GC's own insurer could sue a subcontractor after paying out a claim — which might seem like it benefits the GC, until the sub's insurer does the same thing back, or until the sub simply refuses future work with a GC whose insurer has a reputation for chasing subrogation claims against trade partners. GCs require mutual waivers of subrogation specifically to keep insurers out of disputes between parties who are supposed to be on the same team on a jobsite.

Waiver of Subrogation vs. Indemnification

These aren't competing clauses — they solve different problems and typically appear side by side in the same subcontract. Indemnification determines who ultimately pays for a covered loss between the GC and the subcontractor. Waiver of subrogation determines whether either party's insurance company can separately go after the other party to recover what it paid. A subcontract can have strong indemnity language and still leave a GC exposed to subrogation claims from the sub's own insurer if the waiver isn't in place — they need to work together.

Getting It Right: Contract Language AND Policy Endorsement

A waiver of subrogation needs to exist in two places to actually work: the contract language requiring it, and an actual waiver-of-subrogation endorsement on the underlying insurance policy. Contract language alone doesn't bind the insurance company if the policy itself doesn't waive the right — a common gap, similar to the additional insured issue. Verifying the endorsement is actually on the policy — not just assuming the contract language covers it — is part of a complete certificate of insurance tracking process.

General information only — not legal advice. Whether your specific contract and policy language achieves an enforceable waiver of subrogation depends on the exact wording used and your state's law. Have your attorney and insurance agent both review it.
