Land Records System

As of September 3, 2019, Marathon County has implemented the Transcendent Technologies Ascent Land Records Suite. Land and tax related information is available at ascent.co.marathon.wi.us/ascentlandrecords.

Public Records

Under Wisconsin law, the presumption is that any government record is open for public inspection. Access to records may be denied if there is a specific statute authorizing non-disclosure or if the custodian of the records determines after performing a balancing test that the public’s right to know is outweighed by the public benefit to confidentiality. If a request for records is made, that request will be responded to as soon as practicable and without delay. If access is denied, the response will give specific reasons for the denial. An individual denied access can commence a court action to compel disclosure.

For more information on requesting a public record, visit the Public Records webpage.
