Your drywall sub's employee falls off a scaffold and breaks his back. You pull out the sub's certificate of insurance and call the number. The policy was cancelled two months ago. Here is what happens next - and it is your problem now.
This is not a hypothetical. It happens on job sites across the country every week. A subcontractor shows up with a certificate of insurance that looked good six months ago. Nobody re-verified. Then something goes wrong, and the general contractor finds out the hard way that a piece of paper in a filing cabinet is not the same thing as active coverage.
Let us walk through exactly what happens when a sub causes a loss and does not have insurance - the claim flow, your legal exposure, and what you should be doing right now to prevent it.
When a third party is injured or property is damaged on your job site, the first thing your risk manager or insurance agent does is identify whose work caused the loss. If it was the sub's scope, the claim should go to the sub's insurance carrier.
But here is where it falls apart. You call the number on the certificate. The carrier tells you the policy was cancelled for non-payment 60 days ago. Or worse - the sub never had a policy at all and handed you a fraudulent certificate.
Now the claim has nowhere to go except up the chain. And that chain leads directly to you.
When a subcontractor has no active insurance, the claim does not disappear. It finds the next available pocket. Here is the typical flow:
Step 1: The injured party or property owner files a claim or lawsuit. They name everyone they can - the sub, your company, and possibly the property owner. Plaintiff attorneys cast a wide net.
Step 2: The sub's insurance does not respond. Either the policy is cancelled, the limits are exhausted, or the policy never existed. The sub's carrier issues a denial or there is no carrier to contact.
Step 3: The claim hits your GL policy. Your commercial general liability policy responds because you have a duty to maintain a safe job site. Your carrier assigns defense counsel, opens a reserve, and starts spending money. According to construction liability attorneys, a GC's authority over the worksite often establishes a duty to maintain safe conditions for every worker present - regardless of who employs them.
Step 4: Your loss history takes the hit. Even if the claim is eventually resolved, it sits on your loss runs for five years. That affects your experience modification rate, your insurance premiums, and your ability to win bids on future projects.
Bodily injury liability is bad enough. Workers' compensation exposure from uninsured subs is worse.
Most states have statutory employer laws that make the general contractor responsible for workers' comp benefits when an uninsured subcontractor's employee is injured. The logic is simple: the state will not let an injured construction worker fall through the cracks just because his employer cut corners on insurance.
Here is what that means for you as the GC:
According to AmTrust Financial, an uninsured or underinsured subcontractor can increase your workers' compensation premiums for years. If the sub does not have adequate insurance, your policy may be used to pay the claim - and your rates reflect it.
The Missouri Department of Labor puts it plainly: because an uninsured subcontractor has no policy, the general contractor's insurance company may be required to pay the claim and will charge premium for that uninsured sub.
An additional insured endorsement is how you get access to your sub's GL policy when a claim arises from their work. Without it, the sub's policy only protects the sub. With it, the sub's carrier has to defend and indemnify you too.
Here is how it works in plain English:
But there is a catch most GCs miss. According to industry analysis of additional insured endorsements, the specific endorsement form matters enormously. The CG 20 33 form requires a written contract between the named insured and the additional insured. If the sub signed a contract with you but not with the project owner, the owner may not actually have additional insured coverage under the sub's policy - even if the certificate says they do.
The lesson: do not just collect certificates. Verify the actual endorsement forms. Make sure your contract language matches the endorsement requirements. And confirm your additional insured status is backed by the right ISO form - not all endorsements provide the same coverage.
Not every claim happens on the job site in real time. Construction defect claims can surface years after the project is complete. A leaking roof, a cracked foundation, failed waterproofing - these show up long after the sub has moved on.
When a defect claim is filed, the claim typically flows from the owner to the GC, and then from the GC down to the responsible subcontractor. The GC files a third-party claim or cross-claim against the sub. If the sub has insurance, their carrier steps in. If the sub is uninsured - or out of business - the GC absorbs the entire cost.
This is where completed operations coverage matters. Your additional insured endorsement needs to cover both ongoing and completed operations. If you only required CG 20 10 (ongoing) and not CG 20 37 (completed), you have a gap that could cost you everything on a defect claim two years after project completion.
Every GC subcontract should include an indemnification clause that requires the sub to defend and hold you harmless for claims arising from their work. This is standard contractual risk transfer.
But here is the reality: an indemnification clause is only as good as the sub's ability to pay. If a sub with no insurance and $12,000 in the bank is contractually obligated to indemnify you for a $500,000 claim, you are holding a piece of paper - not protection.
That is why contractual risk transfer and insurance verification must work together. The indemnification clause gives you the legal right to recover. The insurance gives you an actual source of recovery. One without the other leaves you exposed.
Also note: many states have anti-indemnification statutes that limit how much risk you can push to a subcontractor. States like Alaska, Arizona, Georgia, Idaho, Indiana, and others prohibit indemnification clauses that require a sub to cover your sole negligence. Know your state's rules before you assume your indemnification language will hold up.
Most GCs collect certificates of insurance at the start of a project and never look at them again. That is how you end up with a cancelled policy and no coverage when you need it.
Here is what a real COI management process looks like:
Before the sub starts work:
During the project:
After the project:
Here is the minimum insurance package you should require from every subcontractor before they set foot on your job site:
These are standard subcontractor insurance requirements used by major general contractors nationally. Adjust limits upward based on project size, owner requirements, and contract specifications.
When your sub does not have insurance, you do not just lose the sub's coverage. You inherit their liability. Your GL policy takes the hit. Your workers' comp premiums spike. Your loss history gets worse. Your ability to bid future work gets harder. And if the claim is big enough, it can threaten your bonding capacity and your business.
The fix is not complicated. It is a system: verify before they start, track while they work, and keep records after they finish. Build it once, enforce it every time, and you close the gap that costs GCs millions every year.
In most states, yes. Statutory employer laws hold general contractors responsible for workers' comp benefits when an uninsured sub's employee is injured on the job. Your carrier pays the claim and charges you the premium. The claim goes on your loss history and can raise your experience mod for years.
An additional insured endorsement adds you (the GC) to your sub's commercial general liability policy. If someone sues you for something the sub did, the sub's policy responds first - before yours. Common forms include CG 20 10 (ongoing operations) and CG 20 37 (completed operations). Without this endorsement, your own GL takes the full hit.
No. A COI is a snapshot at the time it was issued. Policies can be cancelled after the certificate is printed, and you may never be notified. Always verify directly with the carrier and set up expiration tracking so you catch lapses before they become claims.
An indemnification clause gives you the legal right to recover from the sub. But if the sub has no insurance and no assets, that right is worthless in practice. Contractual risk transfer must always be backed by verified insurance - the contract alone is not enough.
At minimum: commercial general liability ($1M/$2M), workers' comp at statutory limits, commercial auto ($1M CSL), and umbrella ($1M or higher). Require additional insured endorsements naming you on both ongoing and completed operations. Require a waiver of subrogation on workers' comp. Verify everything before work begins.
