Minn. Stat. § 518.183: REPLACING CERTAIN ORDERS.

Upon request of both parties the court must modify an order entered under section 518.17 or 518.175 before January 1, 2001, by entering a parenting plan that complies with section 518.1705, unless the court makes detailed findings that entering a parenting plan is not in the best interests of the child. If only one party makes the request, the court may modify the order by entering a parenting plan that complies with section 518.1705. The court must apply the standards in section 518.18 when considering a motion to enter a parenting plan that would change the child's primary residence. The court must apply the standards in section 518.17 when considering a motion to enter a parenting plan that would:

(1) change decision-making responsibilities of the parents; or

(2) change the time each parent spends with the child, but not change the child's primary residence.
