Minn. Stat. § 514.12
At the beginning of the action the plaintiff shall file for record with the county recorder or, if registered land, with the registrar of titles of the county in which it is brought, and of the several counties if the lien be claimed under section 514.04, a notice of the pendency thereof, embracing therein a copy of the summons, omitting the caption.
After such filing, no other action shall be commenced for the enforcement of any lien arising from the improvement described, but all such lienholders shall intervene in the original action by answer, as provided in section 514.11. Any such lienholder not named as a defendant may answer the complaint and be admitted as a party. If more than one action shall be commenced in good faith, all shall be consolidated and tried as one, under such order of the court as may best protect the rights of all parties concerned.
No lien shall be enforced in any case unless the holder thereof shall assert the same, either by filing a complaint or answer with the court administrator, within one year after the date of the last item of the claim as set forth in the recorded lien statement; and, no person shall be bound by any judgment in such action unless made a party thereto within the year; and, as to a bona fide purchaser, mortgagee, or encumbrancer without notice, the absence from the record of a notice of lis pendens of an action after the expiration of the year in which the lien could be so asserted shall be conclusive evidence that the lien may no longer be enforced and, in the case of registered land, the registrar of titles shall refrain from carrying forward to new certificates of title the memorials of lien statements when no such notice of lis pendens has been registered within the period.
