Minn. Stat. § 558.31: SHARE OF PERSON WHO LACKS MENTAL CAPACITY.

When the share of a person who lacks the mental capacity to make decisions, or other person adjudged to lack the mental capacity to conduct the person's own affairs, is sold, that person's share of the proceeds may be paid by the referees making the sale to the guardian who is entitled to the custody and management of that person's estate, if the guardian has executed an undertaking, approved by a judge of the court, to faithfully discharge the trust reposed in the guardian, and will render a true and just account to the person entitled thereto, or that person's representatives.
