New York Times:  “To deter lawsuits, many estate plans include a no-contest clause, which provides that anyone who formally challenges the plan gets nothing. Brooke Astor, the New York philanthropist, had one in her will. Michael Jackson reportedly used one in his living trust, a private document that disposed of most of his assets. . . . These clauses are becoming more important as people live longer, said Dana G. Fitzsimons Jr., a lawyer with McGuireWoods in Richmond, Va., who handles will contests.”
