The warrant rule (recap and depth)

The constitutional text

The Fourth Amendment to the U.S. Constitution:

> "The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."

Article II, Section 11 of the Montana Constitution provides parallel and, in some respects, broader protections. The Montana Supreme Court construes the Montana Constitution independently and has, on occasion, found greater protection under the state charter than the federal floor. (State v. Tackett, 2017 MT 136 and its predecessors.)

What the Montana Code requires

Title 46, Chapter 5 is the controlling statute. The key sections:

• § 46-5-101 — search warrant required for a lawful search
• § 46-5-102 — grounds for issuance
• § 46-5-103 — the affidavit
• § 46-5-105 — contents of the warrant
• § 46-5-108 — execution, including the 10-day service rule
• § 46-5-110 — return of the warrant

How to read a warrant

When an officer hands you a warrant — or holds it up to the window — read it. The four things that matter:

1. The address. A warrant for "314 N. Main" does not authorize entry to "314 ½ N. Main." Montana courts have suppressed evidence where the warrant named the wrong unit.
2. The scope. A warrant for "the defendant's bedroom" does not authorize the kitchen. [Marion v. State, 267 Mont. 299 (1994)] (verify citation against current reporter).
3. The items sought. "Any evidence relating to the offense" is overbroad. The warrant must particularly describe the things to be seized.
4. The date. The warrant must be served within 10 days of issuance (§ 46-5-108). After that, it is stale.

If the warrant is deficient on any of these grounds, you may refuse entry and demand that the officer seek a corrected warrant. You may not physically resist. You may say, calmly, "I am not consenting to entry. I will not resist a lawful warrant. Please slide the warrant under the door." This is the line the courts have consistently rewarded.

Consent searches (in depth)

When consent is valid

A consent search is a search conducted with the voluntary permission of someone with authority over the premises. The officer bears the burden of proving voluntariness. Schneckloth v. Bustamonte, 412 U.S. 218 (1973) sets the federal standard; Montana applies a similar totality-of-the-circumstances test.

Voluntariness is undermined by:

• Threats of arrest or violence
• Promises of leniency
• Claims of authority that are false ("we have a warrant, just let us in")
• Prolonged questioning without breaks
• Intoxication or coercion of the consenter

Who can consent

A person with authority over the premises may consent. This includes:

• The resident
• A roommate with apparent equal control
• A guest in some circumstances (Georgia v. Randolph, 547 U.S. 103 (2006) — a physically present co-occupant may refuse even if the other consents)

A landlord generally cannot consent to a search of a tenant's unit (Chapman v. United States, 365 U.S. 610 (1961)). A hotel clerk generally cannot consent to a search of a guest room. An employer generally cannot consent to a search of an employee's locked desk.

Revoking consent

You may revoke consent at any time during the search. Once you say "I am withdrawing my consent," the search must stop unless the officer has an independent basis to continue. United States v. Dales, 829 F.3d 977 (9th Cir. 2016) and analogous Montana cases.

Your landlord and your home

When a landlord may enter

Montana's residential landlord-tenant act is codified at Title 70, Chapter 24. The relevant entry rules:

• § 70-24-312 — landlord entry. The landlord may enter only at reasonable times, with reasonable notice (24 hours is the customary standard unless waived by emergency), and only for:
• Inspection
• Maintenance
• Showing the unit to prospective tenants, buyers, or lenders
• Compliance with law
• Emergency

What counts as "reasonable notice"

Montana statute requires "reasonable notice" but does not set a fixed number of hours. Twenty-four hours is the customary standard. Emergencies — a burst pipe, a smoke alarm from inside, a credible report of danger — dispense with the notice requirement.

What you can do

• You may refuse entry that is not for a permitted purpose, not at a reasonable time, or without reasonable notice.
• You may refuse entry by saying, in writing, "I am denying entry today. Please give me at least 24 hours' notice in writing and propose a reasonable time."
• If your landlord retaliates (locks you out, raises rent, files eviction) for asserting your rights, that may be a § 70-24-303 retaliation claim.

The lock-change rule (illegal lockout)

A landlord may not lock you out, remove your belongings, shut off utilities, or otherwise force you out without going through the court process. § 70-24-303 prohibits retaliatory or self-help evictions. The remedy is typically a writ of restoration and statutory damages. If your landlord has locked you out, the Montana Legal Services Developer (contact info) maintains a list of low-cost tenant attorneys.

Eviction in Montana

Notice

§ 70-24-422 (termination for cause) and § 70-24-423 (termination without cause at end of lease) set the notice periods:

• Nonpayment of rent: 3-day notice to pay or quit (§ 70-24-422(1)(a))
• Lease violation: 14-day notice to cure or quit
• End of periodic tenancy: Written notice equal to the period of the tenancy (e.g., 30 days for month-to-month), per § 70-24-423
• End of fixed-term lease: No notice required if the lease has expired.

Court process required

If you do not leave by the end of the notice period, the landlord must file a forcible entry and detainer action in justice court. § 70-24-425 and Title 70, Chapter 25. The court will set a hearing, typically within 7–10 days. A judgment may issue, and only the sheriff may execute a writ of possession — not the landlord.

Tenant defenses

• Improper notice
• Retaliation (§ 70-24-303)
• Breach of the landlord's duties (e.g., failure to provide heat, water, or essential services — § 70-24-303 and § 70-24-304)
• Habitability (§ 70-24-211 and following)

These are not DIY defenses. If you receive an eviction notice, the Montana Legal Services Developer (contact) can refer you to a free or low-cost attorney.

Domestic violence and lock changes

A tenant who is a victim of domestic violence may change the locks without landlord permission, and the landlord must be given a key within a reasonable time. § 70-24-311. The statute is narrow: it requires a documented incident (police report, protective order, or court record) and applies only to the actual victim's unit.

The related protective order statute is Title 40, Chapter 15. A victim may petition for an order of protection in district court. Violation of an order of protection is § 45-5-626 — violation of a protective order, a misdemeanor that escalates with repetition.

---

Trespassing on private property

§ 45-6-203 — Criminal trespass. A person commits the offense when they knowingly enter or remain unlawfully in a dwelling or other place. Theft of services (§ 45-6-302) is a related charge.

Trespass is one of the most fact-sensitive charges in the MCA. Whether a person was "knowingly" on the property and whether they were "unlawfully" there turns on the posted signs, the nature of the property, and the prior communication from the owner. A "no trespassing" sign at every entry point, with the owner's contact information, is the cleanest defense for a property owner.

The inverse — when you have a right to be on someone else's property — comes up with easements, prescriptive use, and recreational use statutes (§ 70-17-101 and following, recreational use immunity for landowners who open land for public recreation).

---

Open range and livestock

Montana is an open-range state by default. § 81-4-101 and related. If your property is not fenced, livestock may legally graze on it. The Montana Department of Livestock maintains the official open-range / closed-range designations by county; many Montana counties are open-range in their entirety, others have "area closed" zones.

The collateral consequences matter more than people expect:

• If you hit a cow on the highway, the owner is generally not liable in open-range areas.
• If you own livestock, you have a duty to prevent it from straying onto a closed-range neighbor's property.
• Fence disputes are a centuries-old part of Montana law. § 81-4-201 and following.

---

Abandoned property

If you rent, the landlord's duty to store your belongings after eviction is set by § 70-24-430 and following. A landlord may not simply throw your things out. The procedures are specific; a landlord who fails to follow them risks conversion liability.

If you find abandoned personal property on your land, the rules are different — a landowner has limited rights to dispose of it depending on value. § 70-2-101 (lost property) and § 70-2-102 (mislaid property) provide the basic framework. Theft by acceptance of abandoned property is rare but real.
