A survey of force majeure law in selected states, focusing on key issues to consider when deciding whether to invoke a force majeure clause, including whether courts recognize and enforce contractual notice requirements and how courts interpret catch-all language, such as "other circumstances beyond a party's control." This chart also covers courts' consideration of certain circumstances that may limit the availability of a force majeure defense under state law, including the foreseeability of the force majeure event, the ability of the party invoking force majeure to control the event, whether the event is the proximate cause of non-performance, and whether the party invoking the force majeure clause tried to mitigate the effect of the force majeure event on the other party.
