Montana Legal Calculators

Montana repealed its executor fee schedule, uses the modified Melson formula for child support and allows ten years for wrongful death from homicide. The Montana calculators are below, by topic.

Probate in Montana

Montana no longer has a fixed schedule for executor fees: the old 3% and 2% schedule was repealed, and only reasonable pay applies, along with reasonable attorney fees. The small estate affidavit is inexpensive to obtain but never covers real property. Creditors have four months, and Montana has two very different small estate tracks. There is no state estate tax.

Personal Injury in Montana

Montana gives three years for most injury claims, extended to ten years for wrongful death from homicide. Recovery is barred only when your fault exceeds the combined fault of everyone you are suing. Ordinary claims are uncapped, while medical malpractice has a cap that rises each year. Attorney fees have no statutory cap, only the Rule 1.5 reasonableness standard.

Family Law in Montana

Montana calculates child support with a modified Melson formula that includes a personal allowance, a primary allowance, a standard of living adjustment and a 110-day parenting rule. There is no maintenance formula: a two-part statutory threshold applies, followed by a needs-and-ability analysis. Marital property is apportioned equitably however it was acquired, without regard to fault. A divorce needs 90 days of domicile before filing and 21 days after service.
