What to Do When a Subcontractor's Insurance Lapses Mid-Project

Finding an expired certificate of insurance in your files tells you one specific thing: you no longer have current proof of coverage on hand. It does not, by itself, tell you that the subcontractor's actual policy has lapsed, been cancelled, or stopped providing coverage. A certificate, as state insurance regulators describe it, is only a snapshot of what the policy said at the time it was issued, not the policy itself. In practice, an expired certificate is often just a paperwork gap, the broker renewed the policy on time but never sent an updated certificate, while coverage itself continued without interruption. Before treating this as a coverage emergency, confirm directly with the subcontractor's insurance broker which situation you're actually in. The steps below assume you've confirmed, or can't promptly rule out, that coverage itself is actually the problem, not just the certificate on file.

It's rare to catch a genuine coverage lapse the day it happens. Far more often, what surfaces first is an expired certificate, during a routine certificate review, when a new certificate is requested for a contract renewal, or worst of all, after an incident on site when someone pulls the file and finds the certificate on hand expired weeks or months earlier. If that expired certificate turns out to reflect an actual lapse in coverage rather than just a stale document, the subcontractor has usually already been performing work on site during the gap, which is what makes a confirmed lapse a different, harder problem than catching a certificate that's merely about to expire.

Once you've confirmed with the subcontractor's broker, not assumed from an expired certificate alone, that required coverage has actually lapsed, the first practical step is to pause that subcontractor's work until coverage is back in place. This isn't about punishing the subcontractor; it's about not adding more uninsured work on top of what's already happened. Continuing to let an uninsured crew work on site, especially once you know about a confirmed gap, removes any argument that the general contractor acted reasonably once the problem was identified. If the broker confirms coverage was actually continuous and only the certificate was stale, this step doesn't apply, you just need the updated paperwork.

Request an updated certificate of insurance directly from the subcontractor's insurance broker, not just from the subcontractor, since a broker can usually confirm or issue a current certificate faster and more reliably than relying on the sub to produce one themselves. Check the new certificate the same way you'd check any other: correct named insured, correct additional insured language if your contract requires it, correct coverage types and limits, and a policy period that actually covers the work going forward. A corrected certificate addresses the gap going forward. It does not retroactively cover the period when there was no valid coverage in place, which is a separate issue.

The work performed while that subcontractor's coverage was lapsed happened without the protection your contract assumed was in place. What that actually means for you depends on your own insurance coverage, your contract's indemnification language, how long the gap lasted, and whether anything occurred during that window that could give rise to a claim. This is a question for your insurance broker and, depending on the specifics, your attorney, not something to resolve by guessing at how serious it probably was. Flagging it and getting a professional opinion early is generally far better than discovering the answer only after a claim arises.

Keep a clear written record of the lapse itself and your response to it. This matters both for your own insurance broker's assessment and, if it ever comes to it, for showing that you acted promptly once the gap was identified.

• The date the lapse was discovered and how it was discovered
• The actual dates of the coverage gap, confirmed with the subcontractor's insurer or broker, not estimated
• The date work was paused and the date it resumed with corrected coverage
• Any communication with the subcontractor, their broker, and your own insurance broker about the gap

The conversation with the subcontractor itself matters too, both for resolving the immediate gap and for the relationship going forward. Be direct about what was found, when coverage lapsed as confirmed with their broker, and what needs to happen before work resumes. Avoid framing it as a casual oversight on either side until you actually know why it happened, since a lapse can result from something as simple as a payment timing issue with their insurer or something more serious like a policy being cancelled for cause. Either way, the practical requirement is the same: a corrected certificate before the crew goes back on site, and the subcontractor should understand clearly why that requirement isn't negotiable.

A lapse that goes unnoticed for weeks is usually a sign that certificates weren't being reviewed on a schedule, not just bad luck with one subcontractor. Once the immediate issue is resolved, it's worth reviewing why the gap wasn't caught sooner, whether that's because no reminder was set for that certificate's expiration date, because certificates weren't being checked against the contract's actual requirements, or because the review process relied on one person remembering to check, with no backup if they didn't. On a business running several projects at once, with subcontractors shared across more than one of them, this review is also a good moment to confirm that every active subcontractor on every current project actually has a certificate on file and tracked, not just the one where the gap was just found.

This article describes a general, practical sequence of steps. It isn't legal advice, and it doesn't address what your specific contract, insurance policy, or jurisdiction requires or allows in this situation. If a lapse has actually occurred on one of your projects, loop in your insurance broker and, where the exposure looks significant, your attorney, rather than relying solely on general guidance like this.

For a closer look at what to check on a certificate before filing it, and how to track certificates across many subcontractors and projects so a gap gets caught before it turns into this situation, see our guide to certificate of insurance tracking for general contractors. ConstruDo's permit and insurance reminders let you set a scheduled reminder against each certificate's expiration date, which is the single most effective way to make sure the next renewal doesn't quietly become the next gap.
