Supreme Court Should Not Have Reformed Settlement Agreement/Criteria for “Mutual Mistake” Not Met

The Second Department determined Supreme Cout should not have found that mutual mistake required reformation of a settlement agreement.  The court explained the operative criteria:

“Marital settlement agreements are judicially favored and are not to be easily set aside” … . Although a mutual mistake by the parties may form the basis for reformation of a marital settlement agreement, “the mistake must be so material that . . . it goes to the foundation of the agreement'” … . “[T]o overcome the heavy presumption that a deliberately prepared and executed written instrument manifested the true intention of the parties, evidence of a very high order is required” … . The party seeking reformation must show clearly and beyond doubt that there has been a mutual mistake, and must show “with equal clarity and certainty the exact and precise form and import that the instrument ought to be made to assume, in order that it may express and effectuate what was really intended by the parties'” … . Hackett v Hackett, 2014 NY Slip Op 01715, 2nd Dept 3-19-14
