A federal court in Missouri backed an insurer that paid $875,000 on a $2.5 mn policy and said the company owed nothing more.
The ruling came on March 31, 2026, when the US District Court for the Eastern District of Missouri granted summary judgment to Mount Vernon Specialty Insurance Company in its declaratory judgment case against Chippewa Loft, owner of a vacant stone and masonry church in St. Louis.
The case turned on a point claims professionals know well, even if courts do not always get such a clean shot at it: the insured’s duty to cooperate.
The dispute started with a fire on October 26, 2021. Flames tore through the bell tower of Chippewa Loft’s church property. The building carried $2.5 mn in coverage, subject to a $25,000 deductible.
But the policy did not use standard actual cash value or replacement cost language. It included a Functional Building Valuation Endorsement, and that changed the whole fight.
Under that endorsement, Mount Vernon did not insure a rebuild to original specifications. The policy instead covered repair or replacement through less expensive materials that would preserve the building’s architectural style.
That detail mattered, a lot, because Chippewa Loft never contracted for repairs within 180 days after the loss. Once that deadline passed, the endorsement’s cash settlement provision took over.
From there, the insurer’s payment obligation narrowed to the smallest of three figures: the policy limit, the market value of the damaged building at the time of loss excluding land, or the cost of a functional replacement after accounting for physical deterioration and depreciation. Tight framework. No room for freelancing.
What followed was months of back-and-forth between Mount Vernon and Chippewa Loft’s public adjuster, Paul Abrams of Edwin-Claude, who had sole authority to act for the insured.
Mount Vernon sent over the endorsement in November 2021 and asked for a repair estimate meeting the policy standard. It asked again in February 2022. Then again in March. According to the court record, the responses never got there.
Chippewa Loft eventually submitted an estimate from Leonard Masonry putting the bell tower rebuild at $4,455,077. That figure assumed close matching of the original brickwork and reconstruction of the walls at the existing 32-inch thickness.
Yet the estimate itself said modern construction using a steel frame and brick veneer would cut the cost to somewhere between $1.7 mn and $2.7 mn.
Chippewa Loft’s own adjuster also acknowledged the estimate rested on actual cash value, even though the policy had replaced that standard. Bad setup from the jump.
Mount Vernon rejected the estimate and asked again for one complying with the endorsement. The adjuster answered that the Leonard Masonry number was the only estimate Chippewa Loft planned to submit.
The market value record was not much better. Mount Vernon hired Lauer, Jersa & Associates, which valued the building at $900,000.
Chippewa Loft responded with a report from Greater St. Louis Appraisal valuing the entire property at $2,925,000, though it used an April 2022 valuation date, roughly six months after the fire.
The policy required market value at the time of loss. Chippewa Loft also pointed to a listing brochure and a pre-loss sales contract, both showing $2.955 mn. The court said neither worked under the endorsement because both included land value and reflected the worth of the undamaged property, not the damaged structure by itself.
Facing that gap, Mount Vernon paid $875,000 in May 2022. That number reflected the Lauer, Jersa valuation less the deductible, and the insurer treated it as the minimum undisputed amount owed. Chippewa Loft took the payment but said it was not enough and demanded the remaining $1.625 mn up to the policy limit.
Mount Vernon then went to court for declaratory relief. The procedural record did Chippewa Loft no favors. The company waited 11 months to file an answer.
When it finally did, it brought a vexatious refusal counterclaim, then failed to oppose a motion to dismiss it. It never served initial disclosures, never pursued discovery, and missed the deadline to answer the summary judgment motion. The court treated Mount Vernon’s factual record as admitted.
On substance, the court applied Missouri law and said the insured carried the burden of proving loss valuation in a way consistent with the policy. Chippewa Loft’s submissions missed on every front.
The Leonard Masonry estimate used the wrong valuation method. The appraisal used the wrong date. The brochure and sales contract included land and reflected pre-loss conditions. None satisfied the endorsement.
The court also rejected Chippewa Loft’s argument that Mount Vernon should have done more to explain what the endorsement required.
Missouri law, the judge said, does not require an insurer to walk an insured through the terms of its own policy. The court also found Mount Vernon showed both reasonable diligence and substantial prejudice, the two elements Missouri requires when an insurer denies further coverage based on a breach of the cooperation clause.
That left the result pretty blunt. The court upheld the endorsement as valid and enforceable, found Chippewa Loft failed to cooperate, ruled the $875,000 payment satisfied Mount Vernon’s obligation, and held that the insurer owed nothing else.
For insurers, the case puts real weight behind cooperation clauses, especially when they sit beside specialty valuation endorsements that narrow how a loss gets measured.
It also shows the risk policyholders take when they submit loss materials built on standards their own policy no longer uses. According to Beinsure analysts, the claims lesson is hard to miss: repeated, documented requests for compliant information still matter, and when the record is tight, courts notice.
