Rented, falsified, excluded: what 2026's cases say about trusting a contractor COI

Why these four

Every week, Worth Reading picks the construction insurance stories worth your time. This fall, four of them pointed the same way. Each one turned on something a certificate of insurance can't show by itself.

We read each one for a single question. If you were the general contractor, what would you have needed to see, beyond the certificate, to know the coverage was real? Our white paper on the six ways certificates fail sets out the full list. This brief is the field evidence.

Case 1: certificates for rent

What was reported. Florida authorities charged seven people in an alleged $100 million workers' comp scheme, Insurance Journal reported in September. Prosecutors say shell companies bought thin coverage by underreporting payroll, then rented their certificates of insurance to subcontractors for a fee while crews were paid in cash. Ten insurers are named as alleged victims, and more than $2.4 million was seized.

What the certificate could show. A real policy, a real carrier and real policy numbers. In the scheme prosecutors describe, the certificate may well be genuine. The problem is that the policy behind it was sized for a payroll that didn't include the people on your site.

The check that matters. Make sure the named insured on the workers' comp certificate is the company that signed your subcontract and employs the crew. A certificate issued to a different company is a red flag, whatever it says about limits.

Case 2: coverage from a company that couldn't write it

What was reported. A federal grand jury indicted two Destin, Florida men tied to The Wave Insurance and Hydrogen Deep, according to Insurance Journal. Neither company was licensed to write property and casualty coverage in Florida. Prosecutors allege the men collected more than $651,000 in premiums and issued falsified certificates of insurance. Both pleaded not guilty, and trial is set for December 14.

What the certificate could show. A carrier name. A certificate doesn't tell you whether that carrier is allowed to write the coverage in your state.

The check that matters. Look up the carrier with your state insurance department or the NAIC's Consumer Insurance Search before you accept the certificate. It takes a few minutes, once per carrier, and you can reuse the answer across trades.

Case 3: the exclusion that left nothing to pay

What was reported. An Illinois appellate court ruled that Mt. Hawley owes Stone Development no indemnity for a carpenter killed on his first day at a Waukegan hotel site, Business Insurance reported. The policy's employee injury exclusion applied, and Stone had no workers' comp in force. The estate holds a $2.65 million agreed judgment. Mt. Hawley paid $250,000 toward it.

What the certificate could show. A general liability policy with real limits. General liability usually excludes injuries to the insured's own employees, because workers' comp is meant to cover them.

The check that matters. Treat workers' comp as its own requirement, not a line to skim. If a trade's certificate shows general liability but no workers' comp, or workers' comp that has lapsed, stop and ask before the crew starts.

Case 4: when trades sue each other

What was reported. In Bauer v. Scott Myers and Sons Roofing, the Idaho Supreme Court revived a plumber's negligence suit against a roofer after a balcony railing the roofer allegedly reinstalled gave way, Business Insurance reported. Whether one trade is shielded from suits by another trade's workers, the court said, turns on whether the general contractor controls the work, not on contract labels.

What the certificate could show. Limits and an additional insured box. It can't tell you whether the endorsements behind it will respond when one trade's worker sues another trade, and the GC is pulled in.

The check that matters. This is when real general liability limits, additional insured endorsements and waivers of subrogation get tested. Ask for the endorsements, not just the certificate. See additional insured and waiver of subrogation.

The market backdrop

Carriers are leaning into construction. Zurich said its U.S. construction premiums grew 17% in the first nine months of 2026, while North American rates held flat, Business Insurance reported. When carriers compete for construction business on flat rates, brokers have more room to ask for the endorsements project requirements call for. It's a good time to ask.

What the four cases have in common

None of these stories is about a sloppy certificate. Each turns on a question the certificate can't answer alone.

1. Who does the policy actually cover? The named insured, and whether it's the company on your site.
2. Who wrote it? A carrier licensed for that coverage in your state.
3. What does it leave out? Employee injuries under general liability, which is why workers' comp has to be in force.
4. Will it respond when trades collide? The endorsements themselves, not the boxes that summarize them.

All four questions can be answered before work starts. That's the practical lesson: the certificate is where verification begins, not where it ends.
