Montana Custody Laws: Parenting Time & Relocation

A plain-English reference to Montana custody terminology, joint custody, parenting time, relocation, child preferences, and order changes.

Informational only—not legal advice. Laws and guidelines change. Verify the current rule with the official court resource and a licensed Montana family-law attorney.

Primary law and terminology

Mont. Code Ann. § 40-4-212 (parenting plan factors). In Montana, courts generally describe the schedule as a parenting plan. The court's decision is based on the child's best interests, not simply a parent's preferred percentage of time.

Joint custody and parenting time

No presumption; Montana requires a parenting plan in every case with children.

Child preference

The child's wishes are a listed factor.

Relocation and move-away cases

§ 40-4-217 requires written notice of intent to move, sent 30 days ahead by certified mail.

Changing an existing order

A change in circumstances of the child is required under § 40-4-219.

Where to file

Under the UCCJEA the child generally must have lived in the state for the 6 months before filing (or since birth, if younger). Montana uses 'parenting plan' rather than custody — required in every dissolution with children.

Build a workable Montana parenting plan

Put regular time, holidays, exchanges, communication, and dispute steps in one written plan. Then keep the actual schedule and handoffs organized as circumstances change.
