For a Will to be valid, certain conditions must be met. The testator must have legal capacity, be at least eighteen years old, have testamentary intent, and the will must not be a product of undue influence or duress. The first two requirements are usually relatively easy issues to resolve, but undue influence and duress are not always clear. As the Supreme Court of Florida explained, “[u]ndue influence is not usually exercised openly in the presence of others, so that it may be directly proved, hence it may be proved by indirect evidence of facts and circumstances from which it may be inferred.”
The Fourth District Court of Appeal, in Blinn v. Carlman, stated that, “[w]hen a will is challenged on the grounds of undue influence, the influence must amount to over persuasion, duress, force, coercion, or artful or fraudulent contrivances to such an extent that there is a destruction of free agency and willpower of the testator.” When a will is a product of undue influence, it, by definition, is not the intent of the testator, and therefore courts should not give effect to it.
