XBox: I used to work for a large insurance brokerage, Willis Corroon, and we wrote surety and insurance for FATCO (First American Title) and Chicago Title.
At first blush, I would imagine a loss like this would be covered by either their general or professional liability (Errors and Omissions) policy, depending on how the loss occurred. Or it would be covered under one of their surety programs, and by something like a fidelity bond or a financial guarantee bond. Can’t recall ever coming across something like this, but both FATCO and Chicago Title had extremely robust risk management, loss and insurance programs (which you’d expect, given the nature of their business).
Probably doesn’t answer your question, but I thought I’d take a whack at it.
