A waiver of subrogation is an agreement in which your insurer gives up its right to recover a paid claim from a specific party, usually because a contract you signed requires it. After a loss, the insurer still pays you. It simply cannot turn around and pursue the party named in the waiver, even if that party caused the loss.
You will meet this term in construction contracts and commercial leases, almost always in the insurance requirements section, sitting next to additional insured and certificate demands.
Waiver of Subrogation
An agreement in which one party relinquishes its insurer's right to recover a paid loss from another party, typically required by written contract before the loss occurs.
How does a waiver of subrogation work on a workers comp policy?
Workers compensation is the strictest line for waivers. Under the Recovery From Others condition of the standard policy, the insurer holds subrogation rights against anyone liable for an employee's injury, and unlike general liability, those rights cannot be waived before or after a loss without an endorsement. Some states do not allow the waiver at all.
Where permitted, the WC 00 03 13 endorsement waives the insurer's right of recovery against the person or organization named in its schedule. The form includes optional wording that limits the waiver to work performed under a written contract requiring it. If your general contractor demands a waiver, this endorsement is what your broker orders, and it must be issued before the injury happens.
Why do contracts require the waiver?
An upstream party does not want to be sued by your insurer. Picture a general contractor on a hospital project. Your employee is hurt on site, your workers comp insurer pays $60,000 in benefits, then subrogates against the GC for unsafe conditions. The GC just paid for your claim through its own liability program.
Requiring a waiver of subrogation from every subcontractor stops claims from circulating among project participants and keeps each party's losses on its own policy. The tradeoff runs against you: a waived claim stays on your loss history as a net loss and flows into your experience modification rate, and insurers typically charge a premium for the endorsement.
What is a blanket waiver of subrogation?
A scheduled waiver names one entity. When a contractor signs dozens of contracts a year, underwriters may attach a non-standard blanket endorsement that applies automatically to any party when a written contract requires the waiver. Blanket wording removes a real E&O trap: if a scheduled waiver misses one entity your contract promised to cover, the insurer can still subrogate against that entity, and the resulting dispute lands on the agent who failed to schedule it.
Certificate reviewers check for this too. A COI that does not show the waiver, or shows it without a form number or blanket reference, usually comes back rejected.
Frequently asked questions
Does a waiver of subrogation cost anything?
Usually yes. Many insurers charge a flat fee or a small percentage of premium per waiver, and a blanket waiver carries its own charge. The larger cost is indirect: waived claims stay on your loss history as net losses and can raise your experience mod at renewal.
Can a waiver of subrogation be added after a loss?
No. On workers compensation the waiver must be endorsed before the injury, and policies in other lines generally exclude coverage when recovery rights are signed away after a loss. Get the endorsement issued when you sign the contract, not when a claim appears.
Is a waiver of subrogation the same as additional insured status?
No. A waiver stops your insurer from recovering a paid claim from the other party. Additional insured status gives that party direct coverage under your policy. Construction contracts commonly require both, and each needs its own endorsement.
Do all states allow waivers of subrogation on workers comp?
No. A handful of states prohibit or restrict waiving workers compensation subrogation rights. If you have employees or contracts in more than one state, ask your broker to confirm the waiver is valid where the work is performed.
