Montana
Montana state laws, regulations, court decisions, and active legislation
Overview
Montana's legal system reflects its frontier heritage and libertarian ethos. The state's 1972 constitution is considered one of the most progressive in the nation, with strong privacy, environmental, and individual rights protections. Montana legalized recreational marijuana in 2020 and has adopted permitless carry.
Montana's legal landscape is significantly influenced by federal public lands, which comprise roughly 30% of the state. Water rights, mineral rights, and land use law are critical legal domains. The state has enacted the Montana Firearms Freedom Act claiming that state-manufactured firearms are exempt from federal regulation, though this has not been upheld by federal courts.
Court Structure
Montana's court system includes city courts, justice courts, district courts (organized into 22 judicial districts), the Workers' Compensation Court, and the Montana Supreme Court. Montana does not have an intermediate appellate court — all appeals go directly to the Supreme Court. All judges are elected in nonpartisan elections.

Key Montana Laws (24)

Montana prohibits driving with a BAC of 0.08% or higher, or while impaired by drugs. First offenders face jail, fines, and license suspension. Fourth offenses become felonies with prison time and chemical dependency treatment.
Permitless Carry and Firearms Freedom Act
Montana allows permitless concealed carry for those 18+. No assault weapon bans, magazine limits, or waiting periods. The Firearms Freedom Act claims state-made guns are exempt from federal regulation. Castle Doctrine applies with no practical duty to retreat.

Wrongful Discharge from Employment Act
Montana is the only state that has abolished at-will employment. Employers must have good cause to fire employees who have passed probation (default 1 year). Wrongful discharge remedies include up to 4 years of lost wages. Punitive damages require fraud or malice. This law replaces common-law wrongful termination claims.
Parenting Plans and Best Interest Factors
Montana requires parenting plans in custody cases, with decisions based on the child's best interests. No gender preference is allowed. Parents with domestic violence history face a presumption against custody. Each parent must submit a proposed plan covering the residential schedule, responsibilities, and dispute resolution. Modifications require changed circumstances.
Assault
Montana defines assault as causing bodily injury, threatening injury, or insulting physical contact. Simple assault is a misdemeanor with up to 6 months jail. Aggravated assault with weapons or serious injury is a felony carrying up to 20 years prison.
Aggravated Assault (Battery)
Montana folds battery into its assault statutes. Aggravated assault — causing serious injury or using a weapon — is a felony with up to 20 years prison and $50,000 fine. Restitution to victims is mandatory.
Criminal Possession of Dangerous Drugs
Montana criminalizes possession of dangerous drugs, with penalties varying by substance and quantity. First offenses for most drugs are felonies with up to 5 years prison. Treatment court diversion is available for eligible defendants.
Theft
Montana theft involves taking property to deprive the owner. Theft of $1,500 or less is a misdemeanor; above that amount it becomes a felony with up to 10 years prison. Stealing firearms, livestock, or vehicles brings enhanced penalties regardless of value.
Dissolution of Marriage
Montana grants no-fault divorce when the marriage is irretrievably broken — shown by 180-day separation or serious discord. A 90-day residency is required. Courts handle equitable property division, support, and parenting plans.
Best Interest of the Child — Parenting Plans
Montana custody decisions follow the child's best interest, weighing parental wishes, child adjustment, abuse history, and dependency issues. Courts favor continuing contact with both parents and require detailed parenting plans.
Child Support Guidelines
Montana calculates child support using state guidelines based on both parents' income, healthcare, and parenting time. Deviations require written justification. Modifications are available with substantial change in circumstances or every 36 months.
Minimum Wage
Montana's minimum wage is $10.30 per hour as of 2024, with annual inflation adjustments. Tipped workers must receive the full minimum wage — no tip credit allowed. Very small businesses have a lower $4.00 rate but must comply with federal law if applicable.
Wrongful Discharge from Employment Act
Montana is the only US state that rejects pure at-will employment after a probationary period (default 12 months). Employees can sue for wrongful discharge if fired without good cause. Damages include up to 4 years of lost wages plus possible punitives.
Wage Payment Requirements
Montana requires regular paydays at least every 10 business days. Discharged employees must be paid immediately (or within 15 days under a written policy). Late payment can incur a penalty of up to 110% of wages owed.
Security Deposits
Montana does not cap security deposits, but landlords must return them within 30 days (10 days if no deductions) with an itemized list. Failure to comply allows tenants to sue for the deposit plus damages and attorney fees.
Eviction Notices and Procedures
Montana eviction requires written notice: 3 days for unpaid rent, 14 days to cure other lease violations. Self-help eviction by landlords is illegal and exposes them to damages of three months' rent plus attorney fees.
Montana Limited Liability Company Act
Montana LLCs form by filing articles of organization with the Secretary of State. Members get limited liability protection. The state has no franchise tax and allows relatively anonymous ownership through registered agents.
Montana Consumer Protection Act
Montana's Consumer Protection Act bars unfair or deceptive business practices. Consumers can sue for actual damages or $500 (whichever is greater), plus attorney fees. Willful violations trigger treble damages, and the state can seek $10,000 per violation.
New Motor Vehicle Warranty Act (Lemon Law)
Montana's lemon law covers new vehicles for 2 years or 18,000 miles. After 4 failed repair attempts or 30 days out of service for the same defect, consumers can demand a replacement or refund. Attorney fees are recoverable if litigation is needed.
Intestate Succession
When someone dies without a will in Montana, the spouse usually takes everything if all children are also the spouse's. With children from prior relationships, the spouse gets $150,000 plus half the rest. Otherwise the estate passes to children, parents, or siblings.
Execution of Wills
A valid Montana will must be written, signed by the testator (18+ and of sound mind), and either witnessed by 2 people or notarized. Holographic wills handwritten by the testator are valid without witnesses. Self-proved wills speed up probate.
