If a subcontractor’s insurance expires mid-project, coverage for their work ends on the expiration date while the certificate in your file stays unchanged. Any injury or damage after that date is uninsured by the sub, the additional insured protection you relied on stops, and your own policy becomes the first line of defense.
What actually changes when the policy expires?
Three things change at once, and none of them is visible in your records.
First, the subcontractor has no coverage for new occurrences. A general liability policy responds to occurrences during its policy period; after expiration, an injury on your site is the sub’s uninsured liability.
Second, your additional insured status ends with it. Additional insured status is an extension of the named insured’s policy, added by endorsement and lasting only as long as that policy is in force. When the policy lapses, the endorsement lapses. The contractual promise that the sub’s insurer would defend you is now a promise with nothing behind it.
Third, the certificate says none of this. A certificate of insurance is a summary of the policies on the day it was issued and does not update itself. The file still shows a compliant sub with current dates because those were the dates when the certificate was printed.
What happens if there is a claim after the lapse?
You tender the claim to the sub’s carrier as an additional insured, and the carrier declines: no policy was in force on the date of loss. Your own general liability policy then responds, subject to your deductible or retention, and the claim enters your loss history. Your carrier may pursue the subcontractor for indemnity under the contract, but that is a recovery action against a business partner, not insurance.
If the sub’s policy renewed with a different carrier or different terms, a related gap appears: the renewal may carry an additional insured endorsement that no longer covers completed operations, or a schedule that no longer names your project. Under ISO forms, ongoing operations coverage under CG 20 10 and completed operations under CG 20 37 are separate endorsements that each have to be present, and a renewal can drop one without anyone noticing.
Why didn’t anyone get notified?
Most teams believe the “30 days notice of cancellation” line on the certificate protects them. The ACORD 25 cancellation clause says notice will be delivered in accordance with the policy provisions, and in practice most insurers do not send that notice unless a written contract or endorsement obligates them to. Non-renewal, which is how most mid-project lapses happen, often triggers no notice at all.
A Notice of Cancellation endorsement changes that. It amends the policy and creates an enforceable duty for the insurer to notify the certificate holder before coverage ends, typically 30 days in advance. Without it, wording in the Description of Operations is a courtesy the insurer may or may not extend.
What are the response steps when a lapse is discovered?
- Confirm the lapse with the broker in writing, including the exact date coverage ended and whether a renewal or replacement policy is in force.
- Stop the subcontractor’s work on site until coverage is confirmed, if the contract gives you that right; most subcontracts condition the right to work on maintaining required insurance.
- Notify the subcontractor formally, citing the contract’s insurance clause and the documents required to resume.
- Request the renewal certificate together with the endorsements the contract requires: additional insured for ongoing and completed operations, waiver of subrogation per policy line, primary and noncontributory, and notice of cancellation.
- Review the renewal as a new submission. Check the policy number and dates on each endorsement against the new certificate, the schedule against your entity and project, and the named insured against the contracting entity.
- Hold pay applications until compliance is restored, if the contract allows, and document the hold.
- Record the lapse period, the documents received and the date work was cleared to resume, so the gap is traceable if a claim later falls inside it.
- Check whether any incident occurred during the lapse and report it to your own carrier promptly.
How do you prevent it from happening again?
Prevention is a tracking problem, not a documentation problem. Every policy on every certificate has an expiration date, and the renewal has to be requested before that date, received, and re-reviewed with its endorsements. At the scale of a project with dozens of subcontractors, each with three to five policies renewing on different dates, a spreadsheet and inbox reminders cannot keep up.
Three controls close the gap. Require a Notice of Cancellation endorsement in every subcontract, so the insurer has a duty to warn you. Track expiration dates centrally and send renewal requests ahead of them, with automated follow-up until the documents arrive. Re-review every renewal as if it were new, because the renewal is where endorsements quietly change.
Jones automates the second and third controls: it tracks the expiration date of every policy on every certificate, sends renewal requests and reminders to the subcontractor and broker before coverage ends, and reviews the renewal certificate and endorsements against the contract requirements before the sub’s status returns to compliant. Teams see which subs are approaching expiration and which have lapsed without reading a spreadsheet.
FAQs
Does my additional insured status survive if the subcontractor’s policy expires?
No. Additional insured status is granted by an endorsement on the subcontractor’s policy and ends when that policy ends. If the sub renews with a new policy, the new policy needs its own additional insured endorsement for your status to continue.
Will the insurer notify me before a subcontractor’s policy cancels?
Only if the policy or an endorsement requires it. The cancellation clause on the ACORD 25 defers to the policy provisions, and most insurers do not send notice unless a Notice of Cancellation endorsement obligates them. Wording in the Description of Operations alone does not create that obligation.
Can I stop a subcontractor from working when their insurance lapses?
If your subcontract conditions the right to perform work on maintaining the required insurance, yes, and most do. Confirm the lapse in writing, notify the sub formally, and document the stop and the date work resumed.
What should I check on a renewal certificate?
Everything you checked on the original. Renewals often change carriers, forms and schedules, so confirm the additional insured endorsements cover both ongoing and completed operations, the waiver of subrogation applies to each required policy line, the policy numbers and dates on each endorsement match the new certificate, and the named insured still matches your contract.
Jones tracks every policy expiration across your subcontractors, requests renewals before coverage ends, and reviews each renewal against your requirements so a lapse does not sit unnoticed in a compliant-looking file. See how the Jones Platform handles expiration tracking.
