You can elect to take “an elective-share amount” of the estate, equal to the value of a percentage of the estate. The percentage is determined by the length of time you were married to each other, The following link will take you to the applicable Kansas statute, which explains this and which has the chart for determining the percentage: http://www.kslegislature.org/cgi-bin/statutes/index.cgi
