Title 84. Wills and Succession
§84-143. Gift to witness void - Exception.
All beneficial devises, legacies or gifts whatever, made or given in any will to a subscribing witness thereto, are void unless there are two other competent subscribing witnesses to the same; but a mere charge on the estate of the testator for the payment of debts does not prevent his creditors from being competent witnesses to the will.
