Unfortunately, including an in terrorem (“no contest”) clause in your Will does not make it impenetrable under New York law.
Although New York law recognizes in terrorem clauses as valid,[i] they are narrowly construed by the courts. An in terrorem clause in a Will threatens that if a beneficiary challenges the Will, such beneficiary (and, typically, all of his or her descendants) will be treated as if he or she predeceased the testator, thereby disinheriting the beneficiary. The purpose of an in terrorem clause is to discourage litigation and ensure that the testator’s intentions are carried out.
