No Contest Clause Law and Legal Definition

No contest clause is a provision designed to threaten one into action or inaction. When used in a will this clause assures that no action will be taken to contest the will. The result is that a legal action taken even after no contest clause will negate the devise. The clause threatens to dispossess any beneficiary who challenges the terms of the will. The Uniform Probate Code (UPC) §§ 2-517 and 3-905 allows no contest clauses so long as the person challenging the will doesn't have probable cause to do so.
