Police can come inside on a domestic call when they have a warrant, consent, or an emergency, but not for any reason and not without limits. Entry into a home ordinarily requires a warrant. The recognized exceptions include consent from someone with authority over the home and an emergency, and a domestic call can involve one or both. What officers may do once inside is a separate question. This page covers each. It is part of our Montana Domestic Violence Guide.
The Starting Point: A Warrant
Article II, section 11 of the Montana Constitution provides that the people "shall be secure in their persons, papers, electronic data and communications, homes and effects from unreasonable searches and seizures." Section 10 adds something the federal Constitution does not state in so many words: "The right of individual privacy is essential to the well-being of a free society and shall not be infringed without the showing of a compelling state interest."
By statute, a search may be made under the authority of a search warrant or "in accordance with judicially recognized exceptions to the warrant requirement" (MCA § 46-5-101). Under the Fourth Amendment, the U.S. Supreme Court held in Payton v. New York, 445 U.S. 573 (1980), that police may not make a warrantless and nonconsensual entry into a suspect's home to make a routine felony arrest, and that absent exigent circumstances the threshold of the home may not reasonably be crossed without a warrant.
Four Grounds for Entry or Search
| Ground | What it requires | Source |
|---|---|---|
| Warrant | A search warrant, or an arrest warrant for a person who lives there when there is reason to believe the person is inside. | MCA § 46-5-101(1); Payton v. New York |
| Consent | Voluntary consent from an occupant who shares authority over the home, when no present co-occupant objects. | Georgia v. Randolph |
| Emergency | An objectively reasonable basis to believe an occupant is seriously injured or imminently threatened with such injury. | Brigham City v. Stuart |
| After a lawful arrest | A reasonable search of the arrested person and the area within the person's immediate presence. | MCA § 46-5-102 |
These are federal constitutional minimums and Montana statutes. Montana courts also apply the state constitution's search and privacy provisions, so the analysis in a Montana case does not stop with the federal cases.
Consent From the Other Person in the Home
When someone who lives in the home called for help or opens the door, consent is the first question. In Georgia v. Randolph, 547 U.S. 103 (2006), the Court described the general rule: police may enter and search when they obtain the voluntary consent of an occupant who shares, or is reasonably believed to share, common authority over the property, and no present co-tenant objects.
Randolph's holding is the exception to that rule: "a physically present co-occupant's stated refusal to permit entry renders warrantless entry and search unreasonable and invalid as to him." The refusal has to come from someone who is there and says so.
Randolph was a case about a search for evidence, and the Court said so. Its decision, the Court wrote, "has no bearing on the capacity of the police, at the invitation of one tenant, to enter a dwelling over another tenant's objection in order to protect a resident from domestic violence." That sentence is why an objection at the door may not keep officers out when the call is about violence.
Emergencies and Exigent Circumstances
In Brigham City v. Stuart, 547 U.S. 398 (2006), officers responding to a call about a loud party saw, through a screen door and windows, an altercation in a kitchen and went in. The Court held that police may enter a home without a warrant when they have an objectively reasonable basis for believing that an occupant is seriously injured or imminently threatened with such injury. The officer's subjective motive does not matter. The question is what a reasonable officer would have believed from what could be seen and heard.
Montana's arrest statute adds its own language. The summoning of a peace officer to a place of residence by a partner or family member "constitutes an exigent circumstance for making an arrest" (MCA § 46-6-311(2)(a)). That sentence speaks to making an arrest. It does not say that every such call authorizes a search of the home, and a statute cannot reduce what the constitutions require. Whether a particular entry was justified is decided on its facts.
Two other statutes are worth knowing. All necessary and reasonable force may be used to enter a building to make an authorized arrest (MCA § 46-6-104(3)). And although a person generally may not be arrested at home at night for a misdemeanor committed at another time and place without a judge's direction, that limit does not apply to an arrest under § 46-6-311 for partner or family member assault (MCA § 46-6-105).
What Officers May Do Once Inside
Lawful entry does not open every drawer. After a lawful arrest, an officer may reasonably search the person arrested and the area within that person's immediate presence, to protect the officer, prevent escape, and find fruits or evidence of the offense (MCA § 46-5-102). Officers responding to a PFMA call must also seize the weapon used or threatened to be used in the alleged assault (MCA § 46-6-603(1)). See weapons seized at the scene.
Beyond that, a search for evidence in other rooms, in a vehicle, or on a phone generally needs a warrant or valid consent. Article II, section 11 specifically names electronic data and communications. Phones are covered in texts, photos, and digital evidence.
What to Do, and What Not to Do
- You may say, calmly, "I do not consent to a search." Saying it preserves the issue.
- Do not block the doorway, pull away, or argue physically. Officers who believe someone inside is at risk may enter regardless, and resistance can bring separate charges.
- Do not move, hide, or get rid of anything.
- Afterward, write down for your lawyer what was said at the door, who let officers in, and where they went.
Entry questions are decided later, by a judge, usually on a motion to suppress. Body camera footage of the doorway, where it exists, can be the best evidence of what was said. Our overview of what happens when police are called covers the rest of the response, and our criminal defense pagedescribes the firm's work.
