🎯 A subcontract that makes you "defend and indemnify the GC for their own negligence" is a broad form indemnity clause, and in roughly 42 states anti-indemnity statutes make the "sole negligence" part unenforceable in construction contracts. But unenforceable does not mean safe to sign: your insurance still has to answer for the part that IS enforceable, and if your policy excludes contractual liability you carry that gap personally. The three answers are: sign it, sign it after two fixes, or don't sign yet. This one is almost always "fix two things first."

TL;DR
- A broad form indemnity clause asks you to pay for the GC's OWN negligence; anti-indemnity statutes in about 42 states void the "sole negligence" piece in construction, but intermediate and limited forms often survive.
- The real question is not the clause wording, it is whether your Contractual Liability coverage and your CG 20 10 / CG 20 37 additional insured endorsements will actually fund what you just promised.
- Scan the packet with a free contract-review tool, confirm your ISO endorsement forms, and compare the clause against your state's anti-indemnity statute before you e-sign.
- Total monthly cost of this entire teardown workflow: $0 to roughly $30, depending on whether you add a paid legal-language check.

What a "defend and indemnify for their own negligence" clause actually is
It is a broad form indemnity clause, the most aggressive of the three indemnity types, and it shifts the GC's own fault onto you. Indemnity in a subcontract comes in three flavors, and the word on the exhibit tells you which fight you are in.
| Indemnity type | What you agree to pay for | Typical enforceability (construction) |
|---|---|---|
| Broad form | GC's liability even for the GC's SOLE negligence | Void in ~42 states by anti-indemnity statute |
| Intermediate form | GC's liability unless the GC was 100% at fault | Enforceable in many states, limited in CA |
| Limited form | Only the portion caused by YOUR negligence | Enforceable nearly everywhere |
Definition — Broad form indemnity clause: A contract provision requiring the subcontractor to defend and hold the general contractor harmless from claims including those arising from the GC's own negligence. It is the broadest, most owner-favorable form of the three indemnity types used in commercial construction subcontracts.
When the subcontract says you "indemnify the GC for their negligence" with no carve-out for the GC's fault, you are looking at broad form. Keep reading before you sign, because this is where contractors get hurt twice: once on enforceability, once on insurance.
Can you sign a subcontract with broad form indemnity?
Usually not as written, and here is the decision in plain terms. The clause has two separate problems and you have to clear both.
Problem one — enforceability. In roughly 42 states, an anti-indemnity statute voids any attempt to make a subcontractor indemnify a GC for the GC's sole negligence in a construction contract. California's statute, for example, invalidates such provisions and limits what can be shifted (see Cal. Civ. Code § 2782). Some states go further and bar intermediate form as well; others leave intermediate and limited forms fully enforceable. So the first move is to read your state's statute, not just the clause.
Problem two — insurance. The part of the clause that survives your state's statute still has to be paid by someone, and the plan is almost always your policy. A standard ISO Commercial General Liability policy includes a "contractual liability" exclusion, with an exception that restores coverage for liability you assume under an "insured contract." If your assumed obligation falls outside that definition — or your carrier has modified the exclusion — you are personally funding whatever you promised. That is the gap that hurts after a loss, not during signing.
The decision, stated simply:
- Sign as written — only if your state voids the sole-negligence piece and your CGL confirms contractual liability coverage for what remains. Rare without edits.
- Sign after two fixes — the usual outcome. Fix the clause language and confirm the insurance. Details below.
- Don't sign yet — if your state enforces broad or intermediate form and your policy excludes contractual liability, you are exposed with no backstop.
The two fixes that turn a "no" into a "yes"
Fix one: narrow the indemnity language to match your state. Replace a bare "indemnify for the GC's negligence" with a comparative-fault version — you indemnify "to the extent of the subcontractor's negligence." This is limited form, enforceable nearly everywhere, and most GCs accept it because their own counsel knows the broad form is void in most states anyway.
Fix two: confirm your insurance actually answers. Pull your CGL declarations and verify two things:
- The contractual liability exclusion still carries the "insured contract" exception (unmodified).
- Your additional insured endorsements match what the subcontract demands — commonly ISO forms CG 20 10 (ongoing operations) and CG 20 37 (completed operations). A subcontract that requires both and a policy that carries only one is a gap you will not see until a claim.
Get both in writing from your agent before the ink is dry.

| Step | Tool category | Typical cost |
|---|---|---|
| Scan the packet for indemnity/insurance requirements | Free contract-review tools (several web-based options offer no-cost first passes) | $0 |
| Confirm your ISO endorsement forms | Your insurance agent / broker (no charge to existing clients) | $0 |
| Check the clause against your state statute | State statute databases / state bar self-help pages | $0 |
| Optional: paid legal-language review | Flat-fee contract-review service | ~$25–$30 |
We are not naming a single proprietary scanner here, because no one neutral tool dominates this category and tool names and prices shift frequently. Describe the category, verify any tool's current price yourself before relying on it, and route anything unclear to a licensed construction attorney in your state.

Frequently asked questions
What is a broad form indemnity clause? A broad form indemnity clause requires the subcontractor to defend and hold the general contractor harmless from claims, including those arising from the GC's own sole negligence. It is the broadest and most owner-favorable of the three indemnity types used in construction subcontracts.
What are the three types of indemnity in construction subcontracts? Broad form (you cover the GC's liability even for its sole negligence), intermediate form (you cover the GC's liability unless the GC was 100% at fault), and limited form (you cover only the portion of a claim caused by your own negligence). Limited form is enforceable nearly everywhere; broad form is void in roughly 42 states.
Is a broad form indemnity clause enforceable? In most construction contracts, no — anti-indemnity statutes in roughly 42 states void the "sole negligence" portion. Intermediate and limited forms often survive. Check your specific state statute, such as California Civil Code § 2782, because rules vary.
Does my insurance cover an indemnity clause I sign? Only if your Commercial General Liability policy's contractual liability exclusion keeps its "insured contract" exception and your obligation fits that definition. Any part of the promise that falls outside it is funded personally. Confirm your coverage and your CG 20 10 / CG 20 37 additional insured endorsements with your broker before signing.
Should I sign a subcontract with broad form indemnity? Usually not as written. The common path is to narrow the language to comparative-fault (limited form) and confirm your insurance will answer for what remains. Sign only if both the enforceability and insurance questions clear.
