CG 24 26: Amendment of Insured Contract Definition

CG 24 26 rewrites paragraph f of the CGL's "insured contract" definition so that a contractual assumption of another party's tort liability is covered only when the bodily injury or property damage is caused, in whole or in part, by the named insured or those acting on its behalf, and only to the extent the assumption is permitted by law. Indemnity that the subcontract triggers by the sub's work, rather than by the sub's fault, falls outside. It is less severe than CG 21 39, which deletes paragraph f entirely, but on a subcontractor policy it signals that the indemnity clause may be partly uninsured.

CG 24 26 editions and what changed
EditionWhat changed
07 04Introduced in the 2004 cycle that moved ISO's additional insured forms to "caused, in whole or in part, by." Replaces paragraph f so assumed tort liability is covered only for injury or damage caused in whole or in part by the named insured or those acting on its behalf.
04 13LatestAdds that the contract is an insured contract only to the extent the assumption of tort liability is permitted by law, matching the extent-permitted-by-law limiter in the 2013 additional insured forms. Railroad and design professional carve-outs carry over.

In CG 00 01, paragraph f of the insured contract definition covers that part of any other contract or agreement pertaining to the named insured's business under which it assumes the tort liability of another party to pay for bodily injury or property damage to a third person. Tort liability means liability that would be imposed by law in the absence of any contract. That paragraph is what insures a subcontractor's promise to indemnify the GC and owner.

CG 24 26 replaces paragraph f with a version that adds a proviso: the injury or damage must be caused, in whole or in part, by the named insured or by those acting on its behalf. The 04 13 edition adds that the agreement is an insured contract only to the extent the assumption of tort liability is permitted by law. Because Supplementary Payments for indemnitee defense depend on the insured contract definition, the narrowing reaches defense costs as well as indemnity.

How CG 24 26 behaves in a tender or claim

Consider a fall at a jobsite where the injured worker sues the owner and GC, and the subcontract's indemnity clause applies to claims "arising out of or resulting from performance of the Work." If the facts show the sub's crew contributed to the hazard, the CG 24 26 proviso is satisfied and the indemnity is insured. If the fall resulted from a condition the GC created and the sub's only connection is that the injured person was its employee working on its scope, the indemnity may still be enforceable under the contract and state law, but the sub's carrier will argue it is not an insured contract because the sub did not cause the injury.

That leaves the sub personally exposed for the indemnity, and a sub that cannot pay leaves the GC with a judgment it cannot collect. Additional insured coverage and contractual indemnity are meant to work together; CG 24 26 weakens the indemnity half.

How it compares with CG 21 39 and anti-indemnity laws

CG 21 39, Contractual Liability Limitation, deletes paragraph f altogether, so no tort-liability indemnity is insured beyond the narrow categories in paragraphs a through e. CG 24 26 is narrower than the standard definition but far broader than CG 21 39, and underwriters sometimes offer it as the compromise in contractor classes where they would otherwise attach CG 21 39.

Many states restrict construction indemnity by statute, voiding agreements that indemnify a party for its sole negligence and, in some states, for any of its own negligence. Where the subcontract's indemnity is already limited to the extent of the sub's fault, CG 24 26 may track what the contract can enforce anyway. Where the indemnity is broader and enforceable, CG 24 26 leaves the gap described above. The answer is specific to the state and the contract, which is why Pikorua Security treats it as a review item rather than an automatic pass.

What to require or prohibit in the contract

Prohibit any endorsement that modifies the insured contract definition, and name CG 21 39 and CG 24 26 specifically. If a trade's market makes CG 24 26 unavoidable, approve it by exception with a documented rationale tied to the project state's anti-indemnity law and the subcontract's indemnity wording.

  • Prohibit: CG 21 39, CG 24 26 and any carrier endorsement limiting the insured contract definition.
  • Allow by documented exception: CG 24 26 where the subcontract indemnity is already limited to the subcontractor's fault under governing law.
  • Require: Supplementary Payments for indemnitee defense to remain in force.

How Pikorua Security verifies or flags CG 24 26

Pikorua Security reads every forms schedule and midterm change endorsement for CG 24 26, CG 21 39 and carrier contractual liability limitations, and marks any of them deficient by default against an exhibit that prohibits them. The flag cites the exact paragraph of the insured contract definition that changed.

A risk manager can approve CG 24 26 by exception per project or per vendor. The approval, the reviewer, the governing state and the reason are logged and travel with the vendor's file into the tender defense vault, so the decision is documented if the indemnity is ever tested.

    CG 24 26 on the forms schedule while the certificate describes contractual liability as included.

  2. Flag 02

    Subcontract indemnity triggered by claims "arising out of the Work" even without subcontractor fault, leaving the non-fault portion uninsured.

  3. Flag 03

    Umbrella carries its own contractual liability limitation, narrowing indemnity coverage further above primary.

  4. Flag 04

    Reviewer treats CG 24 26 as identical to CG 21 39 and rejects it without considering the governing anti-indemnity rule, or treats it as harmless and approves it unreviewed.

  5. Flag 05

    Defense of the indemnitee assumed to be covered under Supplementary Payments, though it depends on the narrowed definition.

Insurance exhibit clause

CG 24 26: Insured contract narrowed

Contractual Liability. Subcontractor's commercial general liability and umbrella policies shall insure Subcontractor's indemnity and defense obligations under this Subcontract as an "insured contract" as defined in ISO form CG 00 01, without modification. No policy shall include ISO endorsement CG 21 39 (Contractual Liability Limitation), CG 24 26 (Amendment of Insured Contract Definition), or any endorsement that limits the insured contract definition or deletes Supplementary Payments for the defense of indemnitees, unless Contractor approves the endorsement in writing before Subcontractor begins work. Subcontractor's indemnity obligations are not limited by the insurance it carries, and the absence of insurance for any obligation does not reduce that obligation.

When the claim arrives

Tender defensibility

Indemnity claims against subcontractors often fund the GC's defense when additional insured coverage is disputed. CG 24 26 lets the sub's carrier contest the indemnity on causation, turning an insured contract claim into a fact fight. The defensible position is a file showing the GC prohibited the endorsement, detected it, and either obtained its removal or approved it with a recorded rationale. That record also supports a breach-of-contract claim against the sub for failing to procure the required coverage if the carrier denies.

Frequently asked questions

What does CG 24 26 change?
It narrows paragraph f of the insured contract definition so assumed tort liability is covered only when the injury or damage is caused, in whole or in part, by the named insured or those acting on its behalf, and only to the extent permitted by law.
Is CG 24 26 as harmful as CG 21 39?
No. CG 21 39 deletes paragraph f and removes coverage for nearly all contractual assumption of tort liability. CG 24 26 keeps paragraph f but ties it to the named insured's fault. Pikorua Security flags both; CG 24 26 can be approved by documented exception.
Does CG 24 26 affect additional insured coverage?
Not directly. Additional insured status comes from the additional insured endorsements. CG 24 26 affects the indemnity route: whether the subcontractor's promise to indemnify and defend you is insured.
Why does a state anti-indemnity law matter here?
If state law already limits enforceable indemnity to the subcontractor's share of fault, CG 24 26 may not remove coverage for any obligation the contract can enforce. If state law permits broader indemnity, CG 24 26 leaves the excess uninsured.
