Kan. Stat. § 12-326
Whenever any owner of any tract of land in any such consolidated city has conveyed or shall hereafter convey any part thereof by metes and bounds or by lot numbers without filing a plat thereof in the office of the register of deeds in the proper county, or shall have invested the public with any rights therein by dedication, prescription or otherwise, it shall be the duty of the mayor of said city to cause a notice to be given to the original proprietor of said tract and to any subsequent purchasers, if he or she shall deem the same necessary, that they are required to execute a plat as required by law. Such notice shall specify the tract or tracts required to be platted, and shall demand that such owner or owners file a plat within thirty days from the time of the service of notice on such owners; and such notice shall specify the manner in which such tracts of land shall be platted. The notices provided for shall be served by the city marshal if the parties are residents of the city, otherwise the same shall be served by mail.
