Will Contest Clauses are generally included to prevent children or beneficiaries from attempting to dispute their portion of an estate. In some states they are valid and many others like Florida they are not valid by statute.
Given that a No Contest Clause in a Will is invalid in a Florida Probate case, should they be used in Florida? If your will is contested and the end result under the state statute may be the same, it may provide any benefit to include the no contest language.
Today people move quite often and may have assets in other states that do recognize Will Contest clauses. Given that one of these situations may enable a no contest clause to be enforced, it might be a good idea to include them in your Florida Estate Planning Documents.
