Is Subcontract Insurance Exhibit Review Worth It?

🎯 Having someone check your subcontract insurance exhibit is worth it IF the contract is over roughly $50,000, includes an additional insured or waiver of subrogation requirement you have not evidenced before, or a GC is withholding payment pending a corrected COI. Skip paying a lawyer $300 to $500 an hour IF the job is a small, familiar repeat contract under $25,000 with insurance terms identical to jobs you have already signed. The single mistake that costs money is signing a subcontract that demands a primary and non-contributory endorsement or CG 20 10 plus CG 20 37 that your current policy does not carry, then discovering the gap after a claim.

TL;DR

• A full attorney review of a GC subcontract runs roughly $250 to $500 per hour, and 2 to 4 hours is typical, so budget about $500 to $2,000 for a real read. (Rates vary by market and seniority; see the ABA and your local bar for current benchmarks — verified August 2026.)
• The insurance exhibit is the part that most often breaks a deal, because additional insured status on both ongoing and completed operations is now a near-standard demand in commercial subcontracts.
• You do not need a lawyer to decode most exhibits. You need to match a handful of named endorsements against what your policy actually carries.
• Before you spend a dollar on review, read the exhibit line by line against your own policy declarations and endorsement schedule, or ask your insurance agent to confirm each required endorsement is on the policy — not just checked on a certificate.

Definition — Subcontract insurance exhibit: the schedule attached to a subcontract (often labeled Exhibit C, Exhibit D, or "Insurance Requirements") that lists the coverage limits, endorsements, and certificate language the general contractor requires before you can start work or get paid. It typically names required additional insured endorsements (CG 20 10, CG 20 37), primary and non-contributory language, waiver of subrogation, and the certificate holder details.

Is it worth having someone check my subcontract insurance exhibit?

Yes, if the exhibit contains a requirement your policy does not already evidence. The exhibit is where a signature turns into an uncovered obligation, because the certificate of insurance a GC holds does not create coverage. Only the endorsement on your policy does. A COI is a snapshot; an endorsement is the contract with your carrier.

Here is the mechanic that does not vary by state, so state it plainly. When a subcontract requires you to name the GC as an additional insured, your certificate showing "additional insured: yes" proves nothing on its own. The GC is protected only if your policy carries the actual endorsement, usually CG 20 10 for ongoing operations and CG 20 37 for completed operations. If your agent issued a COI checkbox without the endorsement behind it, you have signed a promise your policy does not keep.

The same is true for primary and non-contributory and waiver of subrogation. Primary and non-contributory asks your policy to pay first and not seek contribution from the GC's insurer. Without the specific endorsement adding that language — commonly CG 20 01 — your policy may still treat the GC's coverage as sharing the loss, which is exactly the outcome the contract was written to prevent. A waiver of subrogation works the same way: it must be endorsed onto your policy so your carrier gives up its right to recover from the GC after paying a claim. In every case, the contract language and the certificate are only as good as the endorsement sitting behind them.

How to verify an exhibit yourself before paying for review

1. Pull your current policy's declarations page and endorsement schedule.
2. List every endorsement number the exhibit demands (CG 20 10, CG 20 37, CG 20 01, waiver of subrogation).
3. Match each one against your policy's actual endorsement list — not the certificate.
4. For any gap, email your agent and ask for a written confirmation that the endorsement can be added and at what cost.
5. Only escalate to a lawyer if the exhibit contains indemnity or defense obligations that conflict with what your policy will insure.
