Waiver of Subrogation, Explained

A waiver of subrogation stops your insurance company from going after another party to recover what it paid on a claim. Contracts require it so that if something goes wrong on your work, your insurer pays and then leaves the client, general contractor, or landlord alone rather than suing them for reimbursement.

What subrogation is in the first place

When your insurer pays a claim caused by someone else, it generally inherits your right to recover that money from whoever was at fault. That is subrogation. It is normal and it keeps costs down across the system.

A waiver switches it off for a named party. You are agreeing, in advance and in writing, that your carrier will not pursue that specific company even if they contributed to the loss.

Why the other side wants one

A general contractor who hires you does not want to win the job, pay you, and then face a claim from your insurance company months later. The waiver closes that door. The same logic applies to landlords in commercial leases and to clients in vendor and service agreements. Together with additional insured status and primary and noncontributory wording, it is one of the three requirements that show up again and again in construction contracts.

Waiver of subrogation vs. additional insured

They are frequently confused because they usually appear in the same paragraph, but they do different jobs. Additional insured adds someone to your policy so it defends and pays on their behalf. A waiver of subrogation subtracts your insurer's right to come after them afterwards. A contract often requires both, and satisfying one does not satisfy the other.

It has to be endorsed, not just promised

This is where the trouble usually starts. Agreeing to a waiver in a contract does not put one on your policy. The waiver has to be added by endorsement, and it needs to name the right party. A certificate of insurance saying "waiver of subrogation applies" is evidence that someone believes it exists — it is not the endorsement itself.

Two practical points:

• Liability policies commonly accommodate waivers by endorsement, sometimes blanket (covering anyone you have agreed in writing to waive against) and sometimes scheduled to a named party.
• Workers' compensation waivers are treated differently and typically carry a premium charge, often calculated as a percentage of the payroll associated with that job. Blanket waivers on comp are less common than on liability.

Signing a contract that requires a waiver you have not actually secured is a real exposure. If the endorsement was never issued, your carrier retains its recovery rights and can pursue the very party you promised to protect — which becomes a breach-of-contract problem for you.

FAQ

What does a waiver of subrogation actually do?

It gives up your insurer's right to recover claim payments from a specific third party. Your insurer still pays the claim; it simply does not pursue the named party afterwards.

Is a waiver of subrogation the same as additional insured?

No. Additional insured adds a party to your policy so it protects them. A waiver removes your insurer's right to seek reimbursement from them. Contracts frequently require both, and one does not substitute for the other.

Does a waiver of subrogation cost extra?

On liability policies it is often included or carries a modest charge. On workers' compensation it typically carries a premium charge, commonly based on the payroll for the job involved. Terms vary by carrier.

Is a certificate of insurance enough to prove a waiver?

No. The certificate is a snapshot, not the coverage. Ask for the endorsement showing the waiver and confirm it names the correct party.
