In the recent case of Bitco Gen. Ins. Corp. v. Monroe Guar. Ins. Co., No. 19-51012, 2021 WL 955155 (5th Cir. Mar. 12, 2021), certified question accepted (Mar. 19, 2021), the Fifth Circuit Court of Appeals certified to the Texas Supreme Court the question of whether a court can consider extrinsic evidence when determining an insurer’s duty to defend. The underlying lawsuit stems from a construction contract in which J&B Farms of Texas hired 5D, a construction company, to drill a commercial irrigation well through the Edwards Aquifer. Two years after beginning the project, J&B Farms sued 5D and its President for breach of contract and negligence. J&B Farms alleged that while drilling, 5D “stuck the drilling bit in the bore hole, rendering the well practically useless for its intended/contracted for purpose.” 5D then “failed and refused to plug the well, retrieve the drill bit, and drill a new well.” J&B Farms asserted that 5D drilled the well “with unacceptable deviation” and then “abandon[ed] the well.”

5D notified its insurers, BITCO and Monroe, of the lawsuit and demanded a defense from both. BITCO agreed to provide a defense to 5D, but Monroe refused arguing that the alleged property damage fell outside the relevant policy period, and therefore, it had no duty to defend 5D. BITCO then filed a declaratory judgment action seeking a finding that Monroe owed 5D a duty to defend.
