# When a contractor's coverage lapses mid-project: the exposure and the playbook White paper R-06, COI Journal Resource Center. Policies expire, get cancelled for nonpayment, or come back at renewal without the endorsements you asked for. The certificate in your file won't tell you. Here is what's at stake and what to do. Question: What happens to a general contractor if a trade contractor's insurance lapses in the middle of a project? By The editors, COI Journal. November 13, 2026. Docket COIJ-26-0007. Published by Forsured. ## Key findings - A certificate describes coverage on the day it was issued. A lapse after that date doesn't change the paper in your file. - The ACORD 25 says cancellation notice will be delivered according to the policy provisions. That isn't a promise to notify the certificate holder. - When a trade's coverage lapses, its losses look for another pocket, often the GC's policy. A lapsed workers' comp policy is the most dangerous gap. - The defense is a diary of every expiration date, renewal requests before they hit, and a rule that work stops when coverage does. ## The lapse you can't see Coverage stops for ordinary reasons. A policy reaches its expiration date and isn't renewed. A carrier cancels for nonpayment. A renewal is written by a new carrier, with different endorsements. A contractor changes brokers and something falls through. None of those events changes the certificate in your file. It still shows the old dates and the old boxes. And the form doesn't promise to tell you: the ACORD 25 cancellation box says notice "will be delivered in accordance with the policy provisions." Many policies only require notice to the named insured. See [notice of cancellation](https://coijournal.com/dictionary/notice-of-cancellation/). ## What's exposed When a trade's coverage lapses, its losses don't disappear. They look for the next pocket. - **Injuries to the trade's own workers.** If workers' comp lapses, an injured worker may look to the GC. General liability usually excludes the insured's own employees, so it won't fill the hole. In a 2026 Illinois ruling [reported by Business Insurance](https://www.businessinsurance.com/insurer-prevails-in-coverage-dispute-over-carpenters-death/), a general liability carrier owed no indemnity for a carpenter's death because the employee injury exclusion applied and the contractor had no workers' comp in force. - **Third-party injury and property damage.** Without the trade's general liability, and the additional insured endorsement on it, claims arising from the trade's work fall to the GC's own policy. That can mean a deductible, a claim on the GC's loss history and a harder renewal. - **Completed operations.** A trade that drops its policy after finishing can leave you without the completed operations coverage your contract required. Defect claims often arrive later. See [completed operations](https://coijournal.com/dictionary/completed-operations/). - **The owner relationship.** If the prime contract required the GC to make sure every trade stayed insured, a lapse is also the GC's contract problem. ## The playbook **Before the job.** Diary every expiration date for every policy on every certificate. Require renewal certificates and endorsements before each date, in writing, in the subcontract. **Thirty days out.** Ask the trade and its broker for the renewal. A renewal certificate with no endorsements is a request for the endorsements, not a pass. **On the expiration date with nothing in hand.** Treat the coverage as gone. Escalate to the trade's owner. Check your subcontract for the right to stop the trade's work, withhold payment, or buy coverage and back-charge. **If you learn of a cancellation.** Confirm it with the broker. Stop the trade's work on site until coverage is replaced. Document every step and date. **At close-out.** Before final payment and release of retainage, confirm completed operations coverage is in place for the period the contract requires, and keep diarying it for that period. ## The rule that saves the most The simplest control is a sentence in every subcontract and a habit on every job: **no coverage, no work.** It turns a lapse from a hidden exposure into a work stoppage someone has to fix the same day. Our white paper on [one set of rules per project](https://coijournal.com/reports/per-project-requirements-and-renewals/) covers how to keep renewals straight across many jobs at once. ## How we wrote this This is a qualitative paper built from the ACORD 25 form text and 2026 reporting by Business Insurance.
