Minn. Stat. § 485.10: ENTRY OF UNREGISTERED CASES.

Every court administrator shall enter upon the proper registers all cases, civil and criminal, which, through a mistake, inadvertence, or neglect of the administrator's predecessor in office, have not been registered. The true date of the filings in such cases shall be entered in the registers, and the entries, when so made, shall have the same force and effect as if made by the court administrator at the proper time; provided, that, in docketing any judgment, the date thereof shall be the time when actually docketed, and the lien thereof shall attach only from such date.
