In all cases, before granting a marriage license the judge or clerk of the district court shall require the applicant for such license to take and subscribe to an oath to the effect that none of the reasons set forth in Kan. Stat. Ann. § 23-2503 exist why such applicant should not be granted a marriage license; and the judge or clerk may in his or her discretion examine witnesses under oath concerning the matters referred to in Kan. Stat. Ann. § 23-2503, as applied to the applicant for such marriage license, and for the purpose of this act shall have power to administer oaths. If the judge or clerk fails to examine such applicant for license as provided in this section, he or she shall be liable to fine for granting license to parties not legally entitled thereto, in any sum not exceeding one thousand dollars ($1,000), to be recovered by indictment or information, with cost.
