An Additional Insured Clause Finally Gets Put to the Test

The situation

'If something happens on their property, is my insurance even going to cover it?' That was the question Luc asked our office on a Tuesday morning, three days after a courier had slipped on an icy walkway at a small commercial plaza his company serviced. He did not know yet whether the answer was yes or no, and neither, it turned out, did his insurer.

Luc had left a job as a letter carrier four years earlier to start a small property maintenance company, cutting grass, clearing snow, and handling light repairs for a handful of commercial clients around Cambridge. The business had grown steadily to roughly seven hundred thousand dollars in annual revenue, still modest by the standards of the plazas and office buildings he served, but enough to keep three part-time crews busy through the winter season. One of those crews was run informally by Marc-Andre, a subcontractor Luc trusted, who worked security shifts on the side and picked up snow-clearing work through Luc's company when the schedule allowed.

The plaza's owner, Amrit, had required in the service contract that Luc's company name Amrit's numbered company as an additional insured on its commercial general liability policy. This is a common requirement in service contracts: it means that if someone is hurt on the property because of the vendor's work, the property owner can call on the vendor's insurance directly rather than relying entirely on its own coverage or on suing the vendor afterward. Luc remembered agreeing to it. He remembered his broker saying something about sending a certificate. What he did not have, when the claim arrived, was a copy of anything showing it had actually been done.

The courier who fell was seriously hurt and had put both Amrit's company and Luc's company on notice of a claim. Amrit's insurer wrote to Luc directly, asking for proof of the additional insured endorsement and warning that without it, the claim and its costs might fall entirely on Luc's company. Luc's own broker could not immediately locate the endorsement either. Two winters' worth of email had been lost in a laptop replacement, and the renewal file from the year the contract was signed was incomplete. Luc was left trying to prove a promise had been kept using records that no longer clearly existed.

What the law actually said

An additional insured endorsement is not automatic. Naming someone as an additional insured in a contract is a promise to obtain that status from your insurer, and that promise binds the party who made it the moment the contract is signed: failing to obtain the endorsement is a breach of contract, and the company that made the promise can be left answering for the loss out of its own pocket. What the promise cannot do is create insurance — the insurer is only on the hook if the endorsement was actually issued and it was in force when the loss happened. A certificate of insurance, the one-page summary brokers often send to satisfy a client quickly, is usually just evidence that a policy exists. It is not the endorsement itself, and it does not always prove that additional insured coverage was actually added. This distinction is the first thing we had to explain to Luc, because it changed what we were looking for.

The second issue was timing. Coverage disputes like this one turn heavily on what was in force on the date of the incident, not what is in force now or what was intended at the time the contract was signed. If Luc's policy had lapsed and been renewed without the endorsement being carried forward, or if the endorsement had been requested but never actually issued, Amrit's company could be left without the protection the contract promised, and the claim could fall back onto whichever policy did respond, likely at a worse rate and with an argument over who was responsible for the gap.

The third issue was the contract language itself. The service agreement Luc had signed years earlier used fairly standard wording requiring additional insured status, but it did not specify a minimum coverage limit or require Luc to provide proof on a fixed schedule. That looseness cut both ways. It meant there was no clean, one-line failure Amrit's lawyers could point to, but it also meant there was no obvious document trail forcing Luc's broker to have kept better records in the first place.

Finally, we had to look at what Marc-Andre's role meant for coverage. Subcontracted snow-clearing work is sometimes excluded or limited under a general liability policy unless it is specifically endorsed, and insurers frequently push back on claims involving winter maintenance precisely because the exposure is high and the paperwork is often thin. Whether Marc-Andre's work fell inside or outside Luc's policy terms turned out to matter almost as much as the additional insured question itself.

We also had to explain to Luc why none of this made him, or Amrit, a wrongdoer in any moral sense. Small service contracts like his are drafted once and rarely revisited, and the additional insured clause had likely been copied from a template Amrit's property manager used for every vendor on the plaza. Nobody had built a system to confirm, year over year, that the promise inside the clause was still being honoured by an actual policy document. That gap between what a contract says and what an insurance file actually contains is common, and it almost never surfaces until a claim forces it into daylight, which is exactly what had happened here.

What we did

1. Pulled every version of the contract and its amendments from Luc's files and Amrit's property manager, because the exact wording of the additional insured clause, and any changes to it over the years, would determine what Luc's company had actually promised and when. This gave us a clean timeline against which to test the insurance records once we found them.
2. Went directly to the insurer's underwriting file rather than relying on Luc's broker's memory, requesting the full policy history including any requested endorsements, declined endorsements, and renewal notes going back to the year the plaza contract was signed. Insurers keep this material even when a broker's own records are thin, and it turned out to be the only reliable source of what had actually happened each year, giving us a starting point that did not depend on anyone's recollection of a contract signed years earlier.
3. Reconstructed the missing certificate history using email metadata, payment records for premium increases tied to added coverage, and the property manager's own file of certificates received from vendors, cross-checking dates against the years Luc's crews had actually serviced the plaza. Because no single source was complete on its own, layering these records against each other was the only way to establish, with reasonable confidence, which years carried the endorsement and which did not, and to do it in a way an adjuster could actually follow.
4. Identified a two-year gap where the endorsement had lapsed after a mid-term insurer switch and had not been requested again until the following renewal, a detail that had been invisible until the underwriting file and the reconstructed certificates were laid side by side. That gap mattered because it meant the incident fell inside a window where Amrit's additional insured status was genuinely uncertain rather than clearly present or clearly absent, which shaped how honestly we could argue the coverage question.
5. Reviewed Marc-Andre's subcontractor status against the policy wording to determine whether winter maintenance performed by a subcontractor, rather than Luc's own employees, was covered at all, since insurers often carve out or limit subcontracted work unless it is specifically endorsed. This mattered because if the answer was no, the claim could be denied outright on that ground alone, regardless of how the additional insured question was eventually resolved, so it needed to be settled early rather than assumed.
6. Opened a coordinated conversation with both insurers, Luc's and the one covering Amrit's company, laying out the reconstructed timeline honestly rather than asserting a certainty we did not have. We shared the gaps in the record along with what we could establish, because a defensible partial record, presented candidly, carried more weight with an adjuster than an overstated claim that might later unravel once the insurer ran its own review of the same documents.
7. Negotiated an allocation of the claim between the two policies and Luc's company directly, given the genuine gap in coverage, rather than litigating the coverage question to a formal conclusion. A negotiated split let every party avoid the cost and delay of a coverage dispute that could have taken well over a year to resolve, and it let us frame the outcome around what Luc's business could actually afford rather than an abstract legal victory that might have taken the company out of business.
8. Rebuilt Luc's insurance file from the ground up, setting up an annual calendar reminder tied to each client contract and a simple shared folder requirement with his broker, so that future endorsements would be confirmed in writing and stored somewhere that would survive a lost laptop. This turned a one-time scramble to reconstruct missing records into a standing system, so the next renewal would produce a document trail automatically instead of depending on anyone's memory of a phone call.
9. Reviewed Luc's other client contracts for the same gap, since the plaza was not his only account with an additional insured requirement, and confirmed with his broker, in writing, which of those endorsements were currently active and which needed to be requested immediately. This closed the door on the same problem resurfacing with a different client the following winter, rather than leaving Luc to discover a second gap the same way he discovered this one, mid-claim and under pressure.

The outcome

The claim was resolved through a negotiated allocation rather than a formal coverage ruling. Amrit's insurer agreed to treat the additional insured status as having been in force close enough to the loss date, in exchange for Luc's insurer and Luc's company sharing a meaningful portion of the settlement directly. It was not the clean answer Luc had hoped for when he first called, and it was not free: his company's share came to a low five-figure amount, paid over several months, plus a modest increase in his premiums at the next renewal.

What it avoided was worse. Without the reconstructed record, the likely outcome was Amrit's insurer denying any obligation to defend or pay under the additional insured clause and pushing the entire claim, plus legal costs to fight over the gap, onto Luc's company alone. The compromise capped Luc's exposure at a number his business could absorb without threatening its cash flow, and it avoided a formal coverage dispute that could have taken well over a year and cost more in legal fees than the disputed amount itself.

Marc-Andre's subcontractor status turned out not to be the problem it first appeared. His winter work was ultimately treated as covered under Luc's policy, since Luc's company retained direction and control over the work even though Marc-Andre performed it, which meant that piece of the dispute closed quietly and did not need to be litigated separately.

Luc kept the plaza contract and, at renewal, his broker confirmed the additional insured endorsement in writing with a copy sent directly to Amrit's property manager. The gap that had made the claim so difficult to resolve came from paperwork that was never designed to survive four years of small-business turnover, not from bad faith on anyone's part, and closing that gap for good was, in the end, worth more to Luc than the settlement amount itself.
