Joint Custody in Minnesota

Last reviewed November 3, 2026

Joint custody in Minnesota describes an arrangement in which both parents share responsibility for a child after a divorce or separation. The phrase is common, but the law treats it as two distinct ideas: one concerns decisions, and the other concerns daily care. This page explains each one, the presumptions that apply, and the factors a judge weighs. It is part of the site’s guide to custody and parenting in Minnesota.

Two Kinds of Joint Custody

Minnesota divides custody into legal custody and physical custody. Each can be sole or joint, and the two labels do not have to match.

Joint legal custody means that both parents hold equal rights and responsibilities for major decisions about the child’s upbringing. The statute names education, health care, and religious training as examples (Minn. Stat. § 518.003, subd. 3(b)).

Joint physical custody means that the child’s routine daily care and control, and the child’s residence, are structured between the parents (§ 518.003, subd. 3(d)). In practice, the child keeps a home with each parent.

A family may therefore have joint legal custody with sole physical custody to one parent. Many orders take this form. Others grant joint legal and joint physical custody together. The site’s page on legal and physical custody explains each label in more depth.

The Presumption for Joint Legal Custody

Minnesota law starts from a favorable position on shared decision-making. When either parent asks for it, the court must presume that joint legal custody serves the child’s best interests (Minn. Stat. § 518.17, subd. 1(b)(9)).

The presumption is rebuttable. In other words, the other parent may present evidence that shared decision-making would not work for this child. Long-standing inability to communicate about the child is one common example.

No Presumption for Joint Physical Custody

Physical custody is treated differently. The statute states plainly that there is no presumption for or against joint physical custody (§ 518.17, subd. 1(b)(7)). Instead, the judge decides the question on the evidence in each case.

Two related points often surprise parents. First, joint physical custody does not require an exactly equal division of time (§ 518.17, subd. 1(b)(8)). Second, a separate statute presumes that each parent will receive at least 25 percent of the parenting time, absent other evidence (Minn. Stat. § 518.175, subd. 1(g)). See Parenting Time in Minnesota.

The Domestic Abuse Exception

The favorable presumption reverses when domestic abuse has occurred between the parents. In that situation, the court must presume that neither joint legal custody nor joint physical custody is in the child’s best interests (§ 518.17, subd. 1(b)(9)).

The term “domestic abuse” carries the meaning given in Minn. Stat. § 518B.01, the order for protection statute. When deciding whether the presumption has been overcome, the court considers the nature and context of the abuse. It also weighs what the abuse means for the child’s safety and development.

How a Court Decides

Every custody decision rests on the best interests of the child. Section 518.17, subd. 1(a) lists twelve factors that the court must consider. Among them are:

• the child’s physical, emotional, cultural, and spiritual needs;
• each parent’s history of providing care;
• the effect of changes to the child’s home, school, and community;
• each parent’s willingness to support the child’s relationship with the other parent; and
• the parents’ ability to cooperate, share information, and keep the child away from conflict.

The court must make detailed findings on each factor and explain how they led to its decision. Moreover, no single factor may control the outcome, and the court may not prefer a parent because of that parent’s gender (§ 518.17, subd. 1(b)(1)–(2)).

When the facts are disputed, the court may appoint a neutral to investigate. See Custody Evaluation in MN and Guardian ad Litems.

Before a contested custody trial, parents are usually required to try alternative dispute resolution, such as mediation or an early neutral evaluation (Minn. Gen. R. Prac. 310.01; see also Minn. Gen. R. Prac. 114). However, the court may not require a facilitative process when one parent claims to be a victim of domestic abuse by the other (Rule 310.01(b)).

Parenting Plans and Custody Labels

Parents who agree on an arrangement may adopt a parenting plan instead of traditional custody labels. A parenting plan sets out a schedule, a method for making decisions, and a way to resolve future disputes (Minn. Stat. § 518.1705).

A parenting plan may use the terms “joint legal custody” and “joint physical custody,” or it may describe the arrangement in other words. Either way, the plan must still serve the child’s best interests.

Effect on Child Support

Joint physical custody does not end child support. Minnesota calculates support from both parents’ incomes and the number of children. The guidelines then apply a parenting expense adjustment based on each parent’s share of overnights (Minn. Stat. § 518A.36).

As a result, a parent with substantial parenting time often pays a reduced amount. However, the parent with the higher income may still owe support even under an equal schedule. The site’s worked child support example shows the adjustment in detail.

Changing a Joint Custody Order

Custody orders are intended to provide stability. For that reason, Minnesota sets a high bar for modification. Generally, a parent must show a change in circumstances and that the current arrangement endangers the child (Minn. Stat. § 518.18). Time limits also restrict how soon a motion may be filed.

The same standard can apply to a request framed as a parenting time change. In Christensen v. Healey, 913 N.W.2d 437 (Minn. 2018), the Minnesota Supreme Court held that a parenting time change that would substantially alter the custody arrangement must be treated as a custody modification. A best-interests showing alone is not enough in that situation. Child Custody Modification explains these standards in detail.
