Insurance attorneys need to know legal issues that will help their clients.
Two common defenses relied upon to prevent an insurance company from avoiding coverage when a judgment has been entered against their insured are “estoppel” and “waiver.” While both theories have been applied by courts to avoid forfeiture of a policy, they normally cannot be applied to change, re-write, or enlarge the risks covered by a policy. This was told us by the Texas Supreme Court in the 2008, case styled, Ulico Casualty Co. v. Allied Pilots Association, and other cases. Stated in a different way, neither waiver nor estoppel can be invoked to bring a non-covered loss within coverage of a policy so as to supply coverage where none exists.
To distinguish between estoppel and waiver, it has been explained that “Waiver presupposes full knowledge of existing rights, while estoppel arises where, by fault of one, another had been induced to change his position for the worse.” This was discussed in another Texas Supreme Court case. It was Massachusetts Bonding and Insurance Co. v. Orkin Extermination Co., Inc., decided in 1967.
