What Your COI Actually Needs — and Why Subs Get It Wrong

What a certificate of insurance actually is

An ACORD 25 certificate of liability insurance is a snapshot. It says: as of today, this business has these policies, with these limits, from these carriers, expiring on these dates. Read the disclaimer at the top — the certificate "confers no rights upon the certificate holder" and "does not amend, extend or alter the coverage afforded by the policies."

That sentence is the whole game. If the GC needs to be an additional insured, the certificate saying "additional insured" doesn't make them one. The endorsement on your policy makes them one. The certificate just reports that it exists. When a claim comes, the carrier reads the policy, not the certificate.

This is why "my agent can just type it on the certificate" is dangerous advice. Requesting language your policy doesn't actually contain isn't a favor — it's a misrepresentation that leaves the GC uncovered and you personally exposed to the difference.

Additional insured: ongoing versus completed operations

Additional insured status extends your General Liability to cover someone else — usually the GC, the owner, the property manager and sometimes the lender — for liability arising out of your work. There are two flavors and the difference matters enormously:

• Ongoing operations (e.g. CG 20 10) covers them while your work is in progress. The day you finish, it stops.
• Completed operations (e.g. CG 20 37) covers them for claims arising after your work is complete — which is when most construction-defect claims actually arrive.

Contracts almost always require both. Certificates frequently show only the first, because the blanket endorsement on the policy only grants ongoing operations. That's the single most common substantive gap we find when reviewing a subcontractor's certificate.

Blanket additional insured endorsements grant status automatically to anyone you've agreed in a written contract to name — which is far more practical than issuing a scheduled endorsement per job. Confirm your blanket form includes completed operations, and confirm it applies "where required by written contract executed prior to the loss."

Primary and non-contributory

Without this wording, when both your policy and the GC's policy could respond, the two carriers share the loss pro rata — and the GC's carrier will chase yours for contribution. With it, your policy pays first and the GC's policy doesn't contribute at all until yours is exhausted.

Every serious construction contract requires it. It is a real endorsement with a real cost, and it must be on your policy. A certificate that types the phrase into the Description of Operations box while the policy has no such endorsement is exactly the kind of paperwork that produces a coverage denial two years later.

Waiver of subrogation

Subrogation is your carrier's right to recover from whoever caused a loss it paid. A waiver of subrogation gives that right up in favor of a specific party — meaning your carrier can't turn around and sue the GC or owner after paying a claim.

GCs require it on General Liability, Commercial Auto and Workers Comp. The Workers Comp waiver is separate and is usually rated as a percentage of premium, so it isn't free. Get it endorsed before the job starts; a retroactive waiver after a loss is not something carriers grant.

Notice of cancellation and the 30-day myth

Contracts routinely demand "30 days written notice of cancellation to the certificate holder." Since the 2009 ACORD revisions, the certificate itself no longer promises that — it says notice will be delivered "in accordance with the policy provisions."

If your contract genuinely requires notice to a third party, it takes a notice-of-cancellation endorsement naming that party. Some carriers offer it; some only offer 10 days for non-payment. Know which you have before you sign a contract promising 30.

The five reasons certificates get rejected

1. Named insured doesn't match the contract. The contract is with "ABC Contracting LLC" and the policy says "ABC Contracting Inc." or a DBA. Entity name mismatches stop payment applications and permit approvals cold.
2. Additional insured missing completed operations. Covered above — the most common substantive gap.
3. Limits short of the requirement. Frequently the umbrella: the contract wants $5M total and the certificate shows $1M GL and a $2M umbrella.
4. Missing waiver of subrogation on Workers Comp. Contractors often get it on GL and forget it costs a separate endorsement on WC.
5. Wrong certificate holder or wrong address. Increasingly certificates are read by automated vendor-management software that matches text exactly. Close doesn't count.

How to make this a non-event

The workable process is simple, and it happens before the job, not during it:

• Send the insurance exhibit of the contract to your agent before you sign it. Requirements you can't meet are far cheaper to negotiate than to breach.
• Have the endorsements bound at policy inception, so the certificate is a printout of coverage you already own.
• Keep a current certificate from every subcontractor you hire, with the same endorsements you're being asked for. Uninsured sub cost gets charged to your policy as payroll at audit.
• Ask your agent for same-day turnaround as a standard, not a favor. Here's how our COI workflow runs.
