Quick Answer: During a custody battle in Montana, the most damaging mistakes include badmouthing the other parent to or in front of your children, violating your court-ordered parenting plan, using your children to gather information, posting about the case on social media, and denying the other parent their scheduled time without a court order. Montana courts decide parenting plans based on the “best interests of the child” under MCA § 40-4-212 — and judges specifically look for which parent supports the child’s relationship with the other parent, and which one doesn’t.

Going through a custody dispute in Missoula, MT is one of the most stressful things a parent can face. The decisions made during this process affect your children’s lives for years. And some of the most common mistakes parents make — out of anger, fear, or exhaustion — are exactly the kinds of things that hurt their case in front of a judge.

This article walks you through what to avoid, why it matters, and what Montana courts are actually looking for when they decide where your children will live and how much time they will spend with each parent.

Every situation is different. Some of these issues may not apply to your case at all, and some may apply in ways not covered here. That is why the most important step you can take is to get a free consultation with a licensed Montana family law attorney before your next court date — not after.

How Montana Actually Decides Custody Cases

Before getting into the mistakes, you need to understand one key fact: Montana does not use the word “custody.”

Montana law uses the term parenting plan. The Montana Code Annotated § 40-4-234 requires that every case involving minor children result in a Final Parenting Plan — a detailed document spelling out where children live, how much time they spend with each parent, and how major decisions get made.

The standard the judge uses is called the “best interests of the child” — defined in MCA § 40-4-212. The judge is not there to punish either parent. The judge is there to figure out what arrangement is best for the children.

The 13 Factors Montana Courts Consider Under MCA § 40-4-212

A Montana judge must consider these specific factors — not just a general impression of who seems like a “better” parent:

1. What each parent wants
2. What the child wants (based on age and maturity)
3. How the child interacts with each parent, siblings, and others who significantly affect the child
4. How well the child is adjusted to their home, school, and community
5. The mental and physical health of everyone involved
6. Whether there has been physical abuse or threats of physical abuse by one parent against the other or the child
7. Whether either parent has a chemical dependency or chemical abuse problem
8. Continuity and stability of care
9. The developmental needs of the child
10. Whether a parent has failed to pay birth-related costs they were able to pay
11. Whether a parent has failed to financially support a child they were able to support
12. Whether the child has frequent and continuing contact with both parents — Montana law presumes this is in the child’s best interests
13. Whether repeated, unnecessary parenting plan amendment actions have harmed the child

That 12th factor is one of the most important things to understand. Montana law starts with the presumption that both parents should be in the child’s life. If your behavior during this process makes you look like you are trying to cut the other parent out, that works against you — not for you.

13 Things to Avoid During a Custody Battle in Montana

1. Badmouthing the Other Parent — Especially in Front of Your Children

This is the single most common mistake parents make, and it can seriously damage your case.

When you criticize the other parent to your children — or even in front of them — you are showing the court you do not support your child’s relationship with their other parent. Under MCA § 40-4-212(l), frequent contact with both parents is presumed to be in the child’s best interest. A parent who undermines that relationship is not acting in the child’s best interest. Courts call the extreme version of this parental alienation — actively working to damage the child’s bond with the other parent — and Montana judges take it seriously. A pattern of alienating behavior can result in less parenting time, not more.

This includes: calling the other parent names in front of your children, sharing adult details about why the relationship ended, saying things like “your dad doesn’t care about you,” expressing anger where your children can sense it, and making negative comments to teachers, coaches, or other adults your children interact with.

What to do instead: Keep adult conflict between adults. When children ask questions, give neutral, age-appropriate answers. Model the co-parenting relationship you want the court to believe you are capable of.

2. Violating Your Current Parenting Plan or Court Order

If a temporary parenting plan or court order is in place, follow it — exactly, every time, without exception.

Failing to comply is not just a tactical mistake. It is a legal problem. Under Montana law, a parent can be held in contempt of court for violating a parenting plan. That can mean fines, make-up parenting time for the other parent, a changed schedule, or other sanctions.

This applies even if you believe the order is unfair — even if the other parent has violated the plan themselves. The right response to a bad order is to go back to court and request a modification through proper legal channels, not to ignore the order on your own.

Common violations parents do not realize count include: returning children late, picking them up early without agreement, canceling the other parent’s scheduled time without cause, taking children out of Montana without required notice, refusing phone or video calls during the other parent’s parenting time, and making major decisions about school or medical care without involving the other parent.

3. Using Your Children as Messengers or Informants

It feels harmless to ask your children how things are going at the other parent’s house. But when those questions are really about gathering information for your case, children pay the price.

Children in parenting disputes already feel caught in the middle. When a parent asks them about the other parent’s home, relationships, or behavior, it forces children to choose sides. They feel disloyal no matter what they say. That stress shows up in their behavior, schoolwork, and emotional health — and judges notice.

Avoid: asking children to report on the other parent’s home, asking them to deliver messages to the other parent, asking them to keep secrets from the other parent, and coaching children on what to say to a Guardian ad Litem or parenting evaluator.

What to do instead: Communicate directly with the other parent. Use text or email so there is a written record of your reasonable efforts to co-parent.

4. Posting About the Case on Social Media

Social media posts are evidence. Courts see them. The other parent screenshots them. Attorneys print them out and place them in front of judges.

This includes: venting about your ex or the court process on any platform, posting photos or videos that could make you look irresponsible, making posts that contradict something you said in court, and posting anything at all about the case — even if your profile is marked private. Private profiles are not as private as most people assume. Friends share posts. Screenshots get taken. Judges have seen it all before.

The safest approach: Say nothing about the case on social media for the entire duration of the custody process. Treat your profiles as if the judge is reviewing them — because they might be.

5. Losing Your Temper — In Court, at Exchanges, or Anywhere

Custody disputes are emotionally brutal. Anger is understandable. But how you manage that anger is something a judge evaluates under MCA § 40-4-212(e) — the mental health of all individuals involved.

Losing your temper at custody exchanges, at school pickups, in text messages, or in the courtroom tells the judge you may not have the emotional stability to put your children’s needs first. It also hands the other parent usable evidence.

• At exchanges: Keep them brief and child-focused. If needed, use a neutral location.
• In written communication: Wait before sending angry messages. Re-read what you wrote and ask: would I be comfortable if the judge saw this?
• In court: Speak calmly and respectfully. Do not interrupt the other party or their attorney.
• On the phone: Assume every call could be recorded.

6. Denying the Other Parent Their Scheduled Parenting Time

Withholding parenting time from the other parent — without a court order authorizing it — is one of the fastest ways to damage your case.

Montana law (MCA § 40-4-212(l)) presumes that frequent contact with both parents is in the child’s best interest. When you deny that contact, you are directly contradicting what the law says is best for your child. Courts view this as evidence that you are more focused on hurting the other parent than on what is good for your children.

If you genuinely believe your child is in danger, take legal steps — talk to your attorney and go through the court — not unilateral action. Even in legitimate safety situations, the process matters.

7. Introducing a New Romantic Partner Too Soon

You are allowed to move on with your life. But the timing and handling of a new relationship matters during an active parenting case.

Introducing children to a new partner before the parenting plan is finalized can confuse or upset them at an already difficult time, give the other parent evidence that your romantic life takes priority over your children’s stability, raise questions about continuity and stability of care under MCA § 40-4-212(h), and complicate overnight schedules in ways that become part of the court record.

If you have a new relationship, keep it separate from your children and from the case until the plan is finalized. Talk to your attorney about how to handle this in your specific situation.

8. Missing School Events, Medical Appointments, or Extracurricular Activities

A judge considers the interaction and interrelationship of the child with each parent (MCA § 40-4-212(c)) and how well the child is adjusted to home, school, and community (MCA § 40-4-212(d)). A parent who shows up — at school plays, sporting events, doctor visits, and school conferences — demonstrates active involvement in the child’s life.

A parent who consistently misses these events communicates the opposite. Showing up at your child’s soccer game even during the other parent’s parenting time is not overstepping — it is showing the court you are invested in your child regardless of whose “turn” it is. Keep a log of your attendance, communications with teachers and doctors, and involvement in school and activities. This documentation can matter in court.

9. Moving or Making Major Changes Without Court Approval

Montana has specific legal requirements around relocation. Under MCA § 40-4-217, if you want to move with your children in a way that would significantly affect the other parent’s parenting time, you must provide proper written notice and — if the other parent objects — obtain court approval before the move. Moving without following these steps can result in being ordered to return, contempt findings, or a negative change in your parenting arrangement.

This rule applies to other major changes too: changing the child’s school without agreement, making significant medical decisions without the other parent, and taking the child out of Montana for an extended period without notice. Always talk to your attorney before any of these situations, not after.

10. Substance Abuse Issues During the Case

Chemical dependency and chemical abuse are explicit factors listed in MCA § 40-4-212(g). If there is any question about substance use in your case — by either parent — it will be addressed.

Be careful about drinking alcohol when you are responsible for the children, being around children after consuming anything that impairs your judgment, and allowing others in your household to engage in substance use around your children. If you are in recovery, that is something worth discussing with your attorney — active, documented recovery efforts can reflect positively. Denial or concealment of a problem will not.

11. Filing Excessive Motions or Making False Accusations

MCA § 40-4-212(m) specifically lists “adverse effects on the child resulting from continuous and vexatious parenting plan amendment actions” as a factor courts consider. Montana law also provides that attorney fees can be assessed against a party who files frivolous or repeated motions (MCA § 40-4-219). Filing motion after motion — or making accusations you cannot support with real evidence — can backfire on you both legally and financially.

False accusations of abuse or neglect are particularly serious. They harm your children, destroy your credibility with the court, and can expose you to legal consequences.

Genuine safety concerns are completely different. If you have real, documented evidence of abuse or neglect, that must be brought to the court’s attention through proper legal channels. Talk to your attorney about how to present legitimate concerns in a way that protects your children and your case — not just fires an allegation.

12. Failing to Pay Child Support

Two of the 13 best interests factors in MCA § 40-4-212 address financial support — subsection (j) and subsection (k). Both are explicitly listed as things “not in the child’s best interests.” If child support has been ordered, pay it on time, every time. Courts view missed support payments as evidence of broader disengagement from parenting — even if circumstances made a single payment difficult.

13. Lying or Exaggerating in Court Documents or Testimony

Never lie to the court. Not in written declarations, not in affidavits, not on the witness stand. Montana judges are experienced at spotting inconsistencies. If you are caught in a lie — or even a significant exaggeration — your credibility is gone, and everything else you say is viewed with suspicion. Exaggerating a minor incident into something more severe often backfires when the other side produces evidence that contradicts your version of events.

What Montana Courts Actually Want to See

Knowing what to avoid is only half the picture. Courts want positive evidence that you put your children’s needs first. These behaviors support your case:

• Follow the parenting plan consistently — every time, without making the other parent ask
• Communicate in writing with the other parent — email and text create a record of your reasonableness
• Show up to everything that matters — school events, doctor appointments, extracurriculars
• Keep your children’s routines stable — same bedtimes, same schools, same activities where possible
• Speak positively about the other parent in front of your children, or say nothing at all
• Encourage phone and video contact between your children and the other parent during your parenting time
• Keep a parenting journal — document school pickups, medical visits, and activities attended
• Work cooperatively toward agreement — courts favor parents who try to resolve disputes without litigation

What If the Other Parent Is the One Making These Mistakes?

Document everything — calmly and factually. Do not retaliate. Do not try to match their behavior. The parent who stays composed and focused on the children almost always comes across better in court.

If the other parent is violating a court order, your attorney can file a motion for contempt. If the other parent is doing something that puts your children at risk, talk to your attorney immediately about emergency protective options. What you should not do is take matters into your own hands. Retaliating by withholding parenting time or escalating the conflict almost always hurts the parent who does it — regardless of who started it.

When to Talk to a Missoula Family Law Attorney

Talk to an attorney before any of these situations — not after:

• Before you file anything with the court
• Before you respond to anything the other parent has filed
• Before you make any changes to the living arrangement, school, or schedule
• Before you consider relocating with your children
• Before you take any action related to safety concerns about your children
• Any time you receive a notice of a court hearing

Many parents try to navigate these cases alone to save money. In very simple, fully agreed situations, that can work. But in any case involving real disagreement, children’s safety concerns, or complex schedules, having a Montana family law attorney on your side can make a meaningful difference — both in the outcome and in how long the process takes.

Frequently Asked Questions

Does Montana use the word “custody”?

Technically, no. Montana law uses the term “parenting plan” rather than custody and visitation. This shift was intentional — it moves away from the idea that one parent wins and one loses. Official court documents will use “parenting plan” and “parenting time.” Most people still use the word “custody” in everyday conversation, and that is fine, but your court documents and orders will look different.

Will the judge talk to my children?

Under MCA § 40-4-214, a Montana judge may interview children in chambers (the judge’s private office) to find out their preferences. A child’s wishes are one of the 13 factors in MCA § 40-4-212. However, courts generally try to protect children from the stress of the courtroom and from feeling like they are being asked to choose between parents. The judge does not have to follow a child’s stated preference — it is one factor among many. How much weight a child’s opinion carries depends on their age, maturity, and the circumstances of the case. This is an area where your attorney’s guidance is especially important.

What is parental alienation, and can it affect my parenting plan?

Parental alienation refers to a pattern of behavior where one parent works to damage or destroy the child’s relationship with the other parent — through negative comments, manipulation, restricting contact, or similar actions. Montana courts take this seriously because frequent and continuing contact with both parents is presumed to be in the child’s best interest under MCA § 40-4-212(l). A parent found to be engaged in alienating behavior may actually lose parenting time as a result. If you believe the other parent is attempting to alienate your children from you, document specific incidents and bring them to your attorney’s attention promptly.

Can I legally record phone calls with my co-parent in Montana?

Montana is a one-party consent state for recording conversations under MCA § 45-8-213. This means a person who is participating in a conversation may legally record it without telling the other party. If you are part of the conversation, you can legally record it. Recording a call you are not part of is illegal. Talk to your attorney before using any recordings as evidence — how they are used and presented in court matters.

What happens if the other parent violates our parenting plan?

A parent who violates a court-ordered parenting plan can be held in contempt of court in Montana. The court can order make-up parenting time, fines, and in serious or repeated cases, modification of the parenting plan itself. Document each violation with dates, descriptions, and any witnesses. Bring that documentation to your attorney. Avoid retaliating by violating the plan yourself — courts expect both parents to follow the order regardless of what the other parent does.

Can I move to another city or state with my children?

Not without following the legal process. MCA § 40-4-217 governs relocation in Montana. If your move would significantly affect the other parent’s parenting time and they object, you will need court approval before the move. Montana courts apply the best interests standard to these decisions. Moving without following proper steps can result in being ordered to return, contempt findings, or a worse parenting arrangement. Talk to your attorney before making any plans to move with your children.

What if my ex and I agree on everything — do we still need attorneys?

Not necessarily, but at least one consultation with an attorney is worth it before you finalize anything. Agreements that seem simple can have long-term consequences around future modifications, child support calculations, and what happens if circumstances change. A family law attorney can review what you have agreed to and flag any issues before the plan becomes a binding court order. S. DeBoer Attorney at Law offers a free initial consultation — there is no cost to get a professional opinion before you sign anything.
