Why Does My Contract Want a Waiver of Subrogation?

What does a waiver of subrogation actually do to my policy?

A waiver of subrogation means your insurance company gives up its right to go after the other party to get its money back. Subrogation is the normal process: your carrier pays a claim, then looks at who caused the loss and tries to recover from them. When you sign a waiver in favor of the general contractor, your carrier agrees in advance that it will not chase the general contractor even if the general contractor helped cause the loss.

That is why the request comes up on almost every commercial subcontract now. The general contractor does not want to hire you, have your carrier pay a claim, and then have your carrier turn around and sue them over the same job. The waiver takes that fight off the table and keeps the working relationship out of court. It is a routine business term, not a sign that someone expects trouble.

The part that matters for you is timing and paperwork. A waiver has to be added to your policy by endorsement, and it has to be there before the loss, not after. On a general liability policy the standard form is CG 24 04. On workers compensation it is a separate endorsement, and California carriers commonly offer a blanket version that applies to every job where a written contract requires one. Signing a contract that promises a waiver you never actually added is the mistake to avoid.

What does primary and non-contributory mean, and how is it different?

Primary and non-contributory decides whose policy pays first, and whether the other policy has to chip in. Primary means your general liability policy responds first for a claim arising out of your work. Non-contributory means the general contractor's own policy is not asked to contribute alongside yours while your limits are still available.

The clearest way to keep the two ideas apart is timing. Primary and non-contributory controls what happens while a claim is open. Waiver of subrogation controls what happens after the claim is paid. One keeps the general contractor's insurer out of the claim, the other keeps your insurer from coming back at the general contractor later. Contracts ask for both because they cover different halves of the same concern.

This is also an endorsement, commonly the CG 20 01 form, and it usually rides along with the additional insured endorsement. Some carriers build the wording into their liability form and some require it to be scheduled. A quick look at your declarations page and the endorsement list is what tells you which situation you are in, and it is not something a certificate alone will prove.

Why does the general contractor want additional insured status on top of all this?

Additional insured status is the coverage itself. It extends your liability policy to protect the general contractor for claims that arise out of your work, so their defense and their settlement can come from your policy rather than theirs. The waiver and the primary wording only shape how that coverage behaves. Without the additional insured endorsement, there is nothing for them to shape.

There is a second form most subcontractors miss. CG 20 10 covers the general contractor for your ongoing operations, meaning while the job is still in progress. CG 20 37 covers them for completed operations, meaning after you have packed up and left. In construction, a lot of claims surface months or years after the work is done, so a contract that names only ongoing operations leaves the longer tail uncovered. If the subcontract asks for both, your certificate needs to show both.

One more point worth knowing before you sign. Additional insured coverage generally responds to claims arising out of your work, not to the general contractor's own mistakes. A contract that appears to ask your policy to cover their sole negligence is running into California anti-indemnity limits, and it is also asking for something a standard endorsement does not provide. That is a good moment to send the insurance page to your broker rather than initial it and move on.

What do these endorsements cost, and what if my policy cannot match the contract?

On the general liability side, additional insured, waiver, and primary and non-contributory endorsements are often included at no charge or added for a modest fee, depending on the carrier and whether you need a blanket version or a scheduled one per job. Blanket forms cost more up front and save you a call before every new contract, which is usually the better trade for a contractor running several jobs at once.

Workers compensation is where the number shows up more clearly. A blanket waiver of subrogation in California is commonly billed as a small percentage of premium, often in the range of two to five percent, with a minimum charge. That is a real line item, but it is small next to losing a job you were already scheduled on, and your broker can quote it before you commit.

The harder problem is a contract that asks for coverage your policy simply does not include, such as a limit above what you carry, completed operations coverage your form excludes, or professional liability for design work on a design-build job. A certificate cannot promise what the policy does not contain, and issuing one that does creates a problem for everyone. The fix is almost always available, either an endorsement, a higher limit, or a different carrier, but it takes a few days, so the time to look is when the contract arrives and not the morning the job starts.

Send us the insurance page before you sign, in English or Vietnamese

Most contract insurance problems are not dramatic. A subcontract names an endorsement form your policy does not carry, a business name is spelled a little differently than on the policy, or the certificate shows ongoing operations when the contract asked for completed operations too. Each one can hold up a start date, and each one is easy to fix with a little lead time.

As an independent brokerage in Fountain Valley, we read the insurance requirements in a subcontract against the policy you actually have, add the additional insured, waiver, and primary and non-contributory endorsements your jobs call for, and issue the certificates the same day where the coverage is already in place. Because we work with several carriers, we can also look elsewhere when your current policy cannot meet what a general contractor is asking for.

Frequently asked questions

What is a waiver of subrogation in a construction contract?

It is an endorsement in which your insurance company gives up its right to recover from the party you name, usually the general contractor or the property owner, after it pays a claim. It has to be added to your policy before the loss. On general liability the common form is CG 24 04, and workers compensation uses a separate endorsement.

What is the difference between waiver of subrogation and primary and non-contributory?

Primary and non-contributory controls what happens while a claim is open, putting your policy first and keeping the other party's policy from contributing. Waiver of subrogation controls what happens after the claim is paid, stopping your carrier from recovering from that party. Contracts commonly ask for both because they address different stages.

Do I need both CG 20 10 and CG 20 37 as a subcontractor?

It depends on what the subcontract asks for. CG 20 10 adds the general contractor as an additional insured for your ongoing operations while the job is underway, and CG 20 37 adds them for completed operations after the work is finished. Many construction claims appear after completion, so contracts often require both.

How much does a waiver of subrogation cost in California?

On a general liability policy it is often included or added for a modest fee, especially in a blanket form. On workers compensation, a blanket waiver is commonly billed as a small percentage of premium, often around two to five percent, with a minimum charge. Your broker can quote the exact amount for your carrier before you agree to it.

What happens if I sign a contract requiring coverage I do not have?

You have agreed to something your policy does not deliver, and it usually surfaces at the worst time, either when the certificate is rejected before the start date or when a claim is filed. A certificate cannot create coverage that is not in the policy. Sending the insurance requirements to your broker before signing is how that gets caught early.
