Section PRP.04.23 — Who May Witness

(a) Any person who, at the time of execution of the will, would be competent to testify as a witness in Court to the facts relating to execution may act as a witness to the will. Subsequent incompetency of a witness is not a ground for denial of probate if the execution of the will is otherwise satisfactorily proved.

(b) A will is not invalidated because signed by an interested witness; but, unless the will is also signed by 2 disinterested witnesses, any beneficial provisions of the will for a witness or the witness' spouse are invalid to the extent that such provisions in the aggregate exceed in value what the witness or spouse would have received had the testator died intestate. Valuation is to be made as of testator's death.
