Minnesota Child Custody: Best Interest Factors

Minnesota determines child custody using 12 best interest factors set forth in Minn. Stat. Section 518.17. These factors guide every custody decision in the state, whether the parents are divorcing, were never married, or are seeking to modify an existing custody order. The court must consider all 12 factors and may not give one factor more weight than another without explanation.

Minnesota’s approach reflects a modern view of custody that prioritizes the child’s stability, safety, and relationship with both parents. The state presumes that joint legal custody is in the child’s best interest and requires parents to submit a parenting plan as part of any custody proceeding.

The 12 Best Interest Factors (Minn. Stat. Section 518.17)

Minnesota law requires the court to consider the following 12 factors when making custody determinations. The court must make detailed findings on each factor.

Factor 1: The child’s physical, emotional, cultural, spiritual, and other needs, and the effect of the proposed arrangement on the child’s needs and development

This is a broad factor that looks at the whole child. The court examines what the child needs to thrive physically, emotionally, and developmentally, and evaluates which custodial arrangement best meets those needs. Cultural and spiritual considerations — such as maintaining connections to a particular community, language, or religious tradition — are explicitly included.

Factor 2: Any special medical, mental health, or educational needs that the child may have that require special parenting arrangements or access to recommended services

If the child has special needs — such as a disability, chronic medical condition, mental health diagnosis, or learning disability — the court considers which parent is better equipped to manage those needs and whether the proposed custody arrangement allows the child access to the necessary services.

Factor 3: The reasonable preference of the child, if the court deems the child to be of sufficient ability, age, and maturity to express an independent, reliable preference

Minnesota does not set a specific age at which a child’s preference counts. The court evaluates whether the child is mature enough to express a genuine, independent preference. The key word is “independent” — the court will assess whether the child’s stated preference reflects their own views or has been influenced by a parent.

The child’s preference is one factor among 13. It is not determinative, even for older children.

Factor 4: Whether domestic abuse has occurred in the parents’ or either parent’s household or relationship

Domestic abuse is a heavily weighted factor. When there is a history of domestic abuse, the court examines the nature, context, and impact of the abuse. Minnesota law creates a rebuttable presumption that joint legal or joint physical custody is not in the child’s best interest when domestic abuse has occurred (Minn. Stat. Section 518.17, Subd. 2).

The abusive parent must overcome this presumption by demonstrating that they have completed an appropriate intervention program, that the abuse was an isolated incident unlikely to recur, and that joint custody would be in the child’s best interest despite the history of abuse.

Factor 5: Any physical, mental, or chemical health issue of a parent that affects the child’s safety or developmental needs

This factor examines whether a parent has a physical illness, mental health condition, or substance abuse issue that could affect the child. The court does not automatically disqualify a parent based on a diagnosis. Instead, it considers whether the condition impairs the parent’s ability to care for the child and whether the parent is managing the condition responsibly.

Factor 6: The history and nature of each parent’s participation in providing care for the child

The court looks at each parent’s track record of involvement in the child’s daily life. This includes feeding, bathing, transporting, helping with homework, attending school events, managing medical appointments, and other caregiving activities. A parent who has been consistently involved in hands-on caregiving has a strong showing on this factor.

Factor 7: The willingness and ability of each parent to provide ongoing care for the child, to meet the child’s ongoing developmental, emotional, spiritual, and cultural needs, and to maintain consistency and follow through with parenting time

This forward-looking factor evaluates whether each parent is willing and able to continue providing quality care. It examines consistency, follow-through, and the ability to prioritize the child’s needs over the parent’s own preferences.

Factor 8: The effect on the child’s well-being and development of changes to home, school, and community

The court considers the impact of disruption on the child. Changing homes, schools, and communities can be stressful for children, and the court weighs this against the potential benefits of the proposed arrangement. A child who is thriving in their current environment may benefit from continuity.

Factor 9: The effect of the proposed arrangement on the ongoing relationships between the child and each parent, siblings, and other significant persons in the child’s life

This factor looks at all significant relationships in the child’s life — not just the parent-child relationship. Sibling relationships, relationships with grandparents, and connections to extended family and community members are all relevant.

Factor 10: The benefit to the child in maximizing parenting time with both parents and the detriment to the child in limiting parenting time with either parent

Minnesota values both parents’ involvement in the child’s life. This factor creates a general preference for maximizing each parent’s time with the child, all else being equal. However, this preference is balanced against the other factors — particularly Factor 4 (domestic abuse) and Factor 12 (the friendly parent factor).

Factor 11: Except in cases involving domestic abuse, the disposition of each parent to encourage and permit frequent and continuing contact by the other parent with the child

This is commonly known as the “friendly parent” factor. The court evaluates whether each parent supports the child’s relationship with the other parent. A parent who actively encourages the child’s relationship with the other parent — facilitating phone calls, being flexible with the parenting schedule, and speaking positively about the other parent — demonstrates a favorable disposition on this factor.

Conversely, a parent who alienates the child from the other parent, interferes with parenting time, or speaks negatively about the other parent in the child’s presence may be viewed unfavorably.

The domestic abuse exception is critical. A parent who limits the child’s contact with an abusive parent is not penalized under the friendly parent factor.

Factor 12: The willingness and ability of parents to cooperate in the rearing of their child, to maximize sharing information, and to minimize exposure of the child to parental conflict

This factor assesses each parent’s ability to co-parent cooperatively. The court looks at whether the parents can communicate effectively about the child’s needs, share information about school, health, and activities, and resolve disagreements without exposing the child to conflict.

High-conflict parents who cannot cooperate may see this factor work against a joint custody arrangement, as joint custody requires ongoing communication and collaboration.

Note: Prior to the 2015 amendment, Minnesota listed a 13th factor — the child’s primary caretaker. This was removed as a standalone factor and is now incorporated into Factor 6 (the history and nature of each parent’s participation in providing care for the child).

Joint Legal Custody Presumption

Minnesota law creates a rebuttable presumption that joint legal custody is in the best interest of the child (Minn. Stat. Section 518.17, Subd. 2). Joint legal custody means both parents share the right and responsibility to make major decisions about the child’s education, healthcare, and religious upbringing.

This presumption means the court will award joint legal custody unless a party demonstrates that joint legal custody is not in the child’s best interest. Common reasons to rebut the presumption include:

• A history of domestic abuse
• A parent’s inability or unwillingness to cooperate in decision-making
• A parent’s substance abuse or mental health issues that impair judgment
• Geographic distance that makes joint decision-making impractical

Joint legal custody does not necessarily mean joint physical custody. It is common in Minnesota for one parent to have primary physical custody while both parents share joint legal custody.

Parenting Plan Requirements

Minnesota requires both parents to submit a parenting plan as part of any custody proceeding. Under Minn. Stat. Section 518.1705, the parenting plan must address:

• A schedule of parenting time with each parent, including regular time, holidays, school breaks, and summer vacation
• A designation of decision-making authority (joint or sole) for education, healthcare, religious upbringing, and extracurricular activities
• A method for resolving disputes between the parents (such as mediation before returning to court)
• A plan for communication between the child and the non-custodial parent (phone calls, video calls, etc.)
• Provisions for transportation between households
• Procedures for modifying the plan as the child’s needs change

If the parents agree, they can submit a joint parenting plan. If they cannot agree, each parent submits their own proposed plan, and the court decides.

Custody Evaluation Process

In contested custody cases, the court may order a custody evaluation conducted by a qualified professional — typically a psychologist, social worker, or other mental health professional. The evaluator conducts a thorough investigation that may include:

• Interviews with each parent, the child, and other significant persons (such as stepparents, grandparents, and teachers)
• Home visits to each parent’s residence
• Psychological testing of the parents (and sometimes the child)
• Review of relevant documents — school records, medical records, police reports, and prior court orders
• Observation of parent-child interactions
• Collateral contacts — conversations with teachers, therapists, coaches, and other people who know the family

The evaluator produces a written report that includes findings, analysis, and a custody recommendation. The report is shared with both parties and the court. While the evaluator’s recommendation is influential, the judge makes the final custody decision after considering the report, testimony, and all other evidence.

Guardian ad litem

In some cases, the court appoints a guardian ad litem (GAL) to represent the child’s best interests. The GAL conducts an independent investigation — similar to a custody evaluation — and provides the court with a recommendation. The GAL may also participate in hearings and present arguments on behalf of the child’s interests.

Modification of Custody Orders

Once a custody order is in place, either parent can seek to modify it. However, Minnesota sets a high bar for modifications to protect children from the instability of frequent changes.

Time restrictions on modification

Under Minn. Stat. Section 518.18(a), no motion to modify custody may be made earlier than one year after entry of the initial decree. If a prior modification motion has been heard (whether or not granted), no subsequent motion may be filed within two years of the prior motion’s disposition — unless an exception applies.

Exceptions to these time restrictions include situations where the court finds persistent and willful denial or interference with parenting time, or has reason to believe the child’s present environment may endanger the child’s physical or emotional health or development.

The modification standard

Under Minn. Stat. Section 518.18(d), the court will not modify a prior custody order unless it finds, based on facts that have arisen since the prior order (or were unknown at the time), that:

• A change has occurred in the circumstances of the child or the parties
• The modification is necessary to serve the best interests of the child
• The child’s present environment endangers the child’s physical or emotional health or development, and the harm of the change is outweighed by the advantage of a change

This endangerment standard applies to all custody modifications regardless of timing — it is one of the most restrictive standards in family law.

Relocation

If a custodial parent wants to relocate with the child, the move may trigger a modification proceeding. Under Minn. Stat. Section 518.175, Subd. 3, a parent must provide at least 30 days’ written notice before moving the child’s residence to a location that would substantially affect the other parent’s parenting time. The other parent can object, and the court will decide whether the move is in the child’s best interest.

What to Do Next

1. Understand the 12 factors. Review each factor and honestly assess how it applies to your family. Understanding the court’s framework helps you prepare a stronger case and set realistic expectations.
2. Document your involvement. Keep records of your participation in your child’s life — school involvement, medical appointments, extracurricular activities, and daily caregiving. This evidence is directly relevant to Factors 6 and 7.
3. Support your child’s relationship with the other parent. The friendly parent factor (Factor 11) carries weight. Demonstrate that you are willing to facilitate the child’s relationship with the other parent, as long as it is safe to do so.
4. Develop a parenting plan. Begin drafting a detailed parenting plan that addresses the requirements of Minn. Stat. Section 518.1705. If possible, work with the other parent to develop a joint plan.
5. Complete the COPE class. If you have not already done so, enroll in the mandatory parenting education program. Completing it early shows the court you take the process seriously.
6. Talk to a family law attorney. Custody cases are high-stakes, and the 12 best interest factors require careful analysis. An experienced Minnesota family law attorney can help you present the strongest possible case. Schedule a free consultation to discuss your situation.

Frequently Asked Questions

Does Minnesota presume joint custody?

Minnesota creates a rebuttable presumption that joint legal custody is in the child’s best interest under Minn. Stat. Section 518.17, Subd. 2. This means the court will award joint legal custody unless a party demonstrates it is not appropriate — due to domestic abuse, inability to cooperate, substance abuse, or other factors. However, there is no presumption of joint physical custody. One parent may have primary physical custody while both share joint legal custody.

How does the “friendly parent” factor work in Minnesota?

Factor 11 evaluates each parent’s willingness to encourage and permit frequent and continuing contact by the other parent with the child. However, the statute explicitly excludes cases involving domestic abuse from this factor. A parent who limits contact due to legitimate safety concerns is not penalized. Conversely, a parent who alienates the child, interferes with parenting time, or speaks negatively about the other parent faces an unfavorable finding.

What are the time restrictions on filing a custody modification in Minnesota?

Under Minn. Stat. Section 518.18(a), no motion to modify custody may be filed earlier than one year after the initial decree. If a prior modification motion has been heard, no subsequent motion may be filed within two years of the prior motion’s disposition. Exceptions include persistent and willful denial or interference with parenting time, or reason to believe the child’s present environment may endanger the child. The modification standard itself requires a showing that the child’s present environment endangers the child — one of the most restrictive standards in family law.

What happens during a Minnesota custody evaluation?

A qualified professional (typically a psychologist or social worker) conducts interviews with each parent, the child, and other significant persons, performs home visits, may order psychological testing, reviews relevant documents (school, medical, and court records), observes parent-child interactions, and contacts collateral sources like teachers and therapists. The evaluator produces a written report with findings, analysis, and a custody recommendation. The process typically takes 2 to 4 months from start to finish.
