Kansas Statutes Chapter 59. Probate Code § 59-605. Preparation of will or provision of will that gives any devise or bequest to writer or preparer

(a) The writer or preparer is related to the testator by blood, marriage or adoption and the devise or bequest is not more than the writer or preparer or the writer's or preparer's parent, children, issue, sibling or spouse would receive under the laws of intestate succession, if the property passed in that manner; or

(b) it affirmatively appears that the testator had read or knew the contents of the will and had independent legal advice with reference thereto. As used in this section, “children” and “issue” shall have the same meaning as provided in K.S.A. 59-501, and amendments thereto.
