A federal judge has ruled an insurer did not interfere with a lease-to-own agreement between the tenant and the former owner of a Main Line mansion that burned down in 2012.

Plaintiff Julie Charbonneau sued Chartis Property Casualty Co. for entering into a settlement agreement with the property's owner without her consent. U.S. District Judge William Yohn Jr. of the Eastern District of Pennsylvania's ruling this week comes two months after he dismissed the bulk of Charbonneau's claims against Chartis, allowing the case to proceed on the single remaining claim of intentional interference.

Charbonneau, who was attempting to buy and rebuild the Villanova estate Bloomfield, alleged Chartis convinced former owner Jerald Batoff to settle his insurance claim for less than the full coverage amount without Charbonneau's input—Charbonneau's lease-option agreement stipulated that she approve any insurance settlements. Prior litigation between Charbonneau and Batoff resulted in Charbonneau being paid $11 million of the $18.5 million Chartis agreed to pay Batoff for the fire damage.
