Minn. Stat. § 573.17

If it appears that the real property so descended was not alienated by the heir at the time of the commencement of the action, the court shall order that plaintiff's debt, or the proportion thereof which the plaintiff is entitled to recover, be levied upon such real estate, and not otherwise; and every judgment rendered in such action has preference as a lien on such real estate, to any judgment obtained against such heir for a personal debt.
