What Is a Waiver of Subrogation? A Clearer Explanation for Business Owners

Subrogation is the insurer's right to step into the insured's shoes and pursue a third party who caused a covered loss. If your carrier pays a fire claim and the fire was caused by a neighboring contractor, the carrier may have the right to sue that contractor for reimbursement. A waiver of subrogation eliminates or limits that right.

That distinction matters because a waiver does not expand coverage. It does not make a denied claim covered. It does not add another party as an insured. It only affects the recovery process after a covered claim has been paid. Understanding that role makes the contract language much easier to evaluate.

On a commercial general liability policy, a waiver of subrogation is typically added through endorsement CG 24 04 (Waiver of Transfer of Rights of Recovery Against Others to Us). On a workers' compensation policy, the equivalent endorsement is WC 00 03 13. These are ISO standard forms used across most commercial carriers.

The endorsement can be scheduled — naming the specific party the waiver applies to — or blanket, applying to any party the insured has agreed in writing to waive subrogation rights against prior to a loss. Blanket waivers are common in construction and commercial real estate because they avoid the need to update the policy every time a new contract is signed. Scheduled waivers are more precise but require more administrative maintenance.

The most common problem is not that the waiver is a bad idea. It is that the contract requires it and the policy does not actually have the endorsement. A certificate of insurance can note that a waiver applies, but a certificate is not the policy. If the endorsement is missing and a claim occurs, the carrier may still pursue subrogation despite the contract language.

This creates a contract breach problem even when the insurance claim itself is paid. The party who required the waiver may have a legal claim against the party who failed to deliver it. That is why confirming the endorsement is on the policy — not just referenced on the certificate — is the right step before work begins.

Blanket waivers are efficient for businesses that sign many contracts. A single endorsement covers all qualifying agreements, and the policy does not need to be updated for each new project or vendor. Most carriers offer blanket waivers at little or no additional cost on commercial general liability policies.

The tradeoff is that blanket waivers apply broadly. If a business regularly works with parties who create significant loss exposure, giving up recovery rights across the board may affect how the carrier views the account over time. It is worth asking the carrier whether blanket waiver language affects underwriting, pricing, or claim handling on the specific policy type.

Workers' compensation waivers are handled separately from general liability. The WC 00 03 13 endorsement is the standard form. It is commonly required in construction contracts, especially when a general contractor wants to limit recovery exposure from a subcontractor's carrier after an employee injury on the job.

Some states have restrictions on workers' compensation waivers, and some carriers charge an additional premium for the endorsement. Confirming the endorsement is in place on the WC policy — not just the GL — is part of a complete contract compliance review.

Before signing a contract that requires a waiver of subrogation, confirm which policy is supposed to carry it, whether the endorsement is scheduled or blanket, whether the carrier has been notified, and whether there is any premium impact. Also confirm the effective date: a waiver that is added after a loss has already occurred will not help.

For businesses that sign contracts regularly, a periodic review of all waiver obligations across active policies is a practical risk management step. It is easier to find a gap before a claim than to explain it after one.
