The law in plain words
Montana does not order "custody." It sets a "parenting plan" and weighs the best-interest factors in section 40-4-212. The law leans toward frequent contact with both parents.
A parenting plan, not custody
Montana courts set a parenting plan. Where the child lives on given days, how big decisions are made, and how the parents handle exchanges and holidays.
So "full custody" is not really a Montana term. The goal is a plan that works for this child.
Frequent contact is the aim
Montana law assumes a child does best with frequent, ongoing contact with both parents, and ideally close to equal time when that serves the child.
That is not a promise of a 50/50 split. It is a leaning the court starts from and tests against the facts.
What the court weighs
Section 40-4-212 looks at the child's wishes, the child's bond with each parent and siblings, how settled the child is, everyone's health, any abuse, stability of care, and the child's developmental needs.
Evidence tied to those points is what helps.
What the numbers do not show
The figures above show where Montana children live, not what any parenting plan says. Use them as background only.
Your evidence and the child's needs shape the plan.
Building the record
Note the care you give and your time with the child, each with a date and the proof behind it. Keep the messages that explain any change.
Casewell keeps those notes and files together. So a lawyer can read a clear timeline.
Before you file in Montana
Save any existing order, track your time with the child for a few weeks, and draft the parenting plan you want.
A Montana family-law lawyer can weigh it against section 40-4-212 before you file.

Does Montana use custody or a parenting plan?
Montana sets a parenting plan. It says where the child lives on which days, how the big decisions get made, and how holidays and handovers work.
Does Montana favour 50/50 parenting?
Montana law wants the child to have frequent contact with both parents. Also, close to equal time when that works for the child. It is a leaning, not a fixed rule.
Does Montana publish a full-custody success rate?
No. Public data does not give a complete percentage of Montana cases in which mothers or fathers receive sole legal and physical custody. Household statistics describe where children live, not court outcomes.
Do these statistics show that mothers get custody more often in Montana?
They show the sex of the household householder in a living-arrangement table. They do not show legal custody, parenting-time percentages, the reason for the arrangement, or whether a court was involved.
Can documentation improve my chances of custody?
Yes. Good records can definitely improve your chances. They help you arrive prepared with clear, dated evidence in the right format. They give your lawyer a head start, saving time and fees. They cannot guarantee an outcome, but they can strengthen your case.
What should I record first?
Start with the current arrangement, then record each material change with the date, what was expected, what you observed, the source, the child-related effect, your response, and the outcome. Use Casewell to keep the entry and supporting file together.
