Minn. Stat. § 379.07: TOWNS WITH SAME NAME.

If the commissioner of revenue, on comparing the abstracts of the reports from the several counties, finds that two or more towns have the same name, the commissioner shall transmit to the auditor of the proper county the name to be altered, and the county board shall, at its next meeting thereafter, adopt for such town a different name. When such name is adopted the county auditor shall inform the commissioner of revenue, as before directed.
