Why the clause exists
Most founders meet commercial insurance for the first time inside someone else's contract. A customer agreement, a site access form, or a lease arrives with an insurance section, and suddenly a deal is waiting on coverage you may not carry yet. The clause is the counterparty protecting itself: if your work injures someone or fails expensively on their premises or their project, they want the claim to land on your insurer, not on them.
Reading the clause well matters twice. Buying less than it requires stalls the signature; buying more than it requires wastes premium. The clause is a list of specific, decodable asks, and every one of them is either something you carry, something you can add, or something you can negotiate.
The usual asks, decoded
Lines and limits come first: general liability at one million per occurrence and two million aggregate is the most common floor, with tech E&O and cyber appearing once your product touches their operations or data, and workers' compensation whenever your people set foot on their site. When a contract demands five million in liability, the extra usually comes from an umbrella policy over your primary rather than a bigger primary.
Additional insured is the ask that confuses people most. It means your liability policy also protects the counterparty for claims arising out of your work, and it arrives in two flavors: a scheduled endorsement naming them specifically, or blanket wording that automatically extends the status to anyone your written contracts require. A policy with blanket additional-insured wording turns this ask into a certificate request; a policy without it turns the ask into an endorsement request to the carrier.
A waiver of subrogation means your insurer agrees not to chase the counterparty to recover what it paid on your claim. A primary and non-contributory requirement means your policy pays before theirs does. Notice of cancellation means they want to hear if your coverage lapses. All three are standard machinery, and all three are things an underwriter prices rather than refuses.
What is negotiable
The insurance clause is part of the contract, and it negotiates like the rest of the contract. Limits are the most commonly negotiated item: a five million demand on a small pilot often relaxes to two once someone asks, because the requirement was pasted from a template sized for bigger vendors. Requirements to carry coverage for years after the work ends, common in claims-made lines, deserve particular attention because they quietly commit you to future premiums.
The practical sequence: send the clause to your broker before you sign, not after. Matching the requirements against what you carry takes a broker minutes, and it converts the insurance section from a closing surprise into a checklist with prices attached.
This page describes coverage in general terms. It is not an offer of insurance, and carrier appetite, policy wording, licensing, and availability govern every quote and every claim.
Common questions
What does additional insured mean in a contract?
It means your liability policy also protects the counterparty for claims arising out of your work for them. Policies with blanket additional-insured wording extend that status automatically when a written contract requires it; without that wording, the carrier adds the party by endorsement.
What is a waiver of subrogation?
After paying your claim, an insurer normally has the right to recover from whoever caused the loss. A waiver of subrogation gives up that right against the counterparty named in your contract. It is a routine, priceable request that most carriers accommodate by endorsement.
Can I negotiate the insurance requirements in a contract?
Usually yes. Limits, required lines, and post-contract coverage periods are negotiated like any other term, and oversized requirements often come from templates rather than actual risk assessments. It is cheaper to negotiate a limit down than to buy coverage you don't need.
How fast can I get the certificate a contract requires?
If the program already carries what the clause asks, a certificate is an administrative document that issues quickly. If the clause requires an endorsement or a new line, carrier turnaround gets added, which is why the clause should reach your broker before signature rather than after.
