The main Kansas background check resource is the state Bureau of Investigation, and you can access anyone's criminal history through this office. Their website allows for online searches by name and there is a $20 fee for each search you do. You can also make your request by mail if you prefer, though the fees will increase. Employers using fingerprint cards can get a more detailed report back.
Another valuable Kansas background check resource is the state’s collection of vital records. You can get copies of anyone's marriage or divorce records, if you make the proper application through the county district court where the record is registered. Each search will cost you $15. Birth and death records are not accessible unless you are an immediate family member. If that is the case, you can apply at the Vital Records office in Topeka for those.
