Wyoming Castle Doctrine: Presumption, No Retreat, and Immunity

Under the Wyoming Castle Doctrine, codified at Wyoming Statutes § 6-2-602, the law presumes you acted in reasonable fear for your life when an intruder unlawfully and forcibly enters your home, which means you can defend yourself — with deadly force if necessary — without first trying to retreat.¹ A companion statute, § 6-1-204, blocks civil lawsuits over that same justified use of force and shifts attorney fees onto anyone who sues you anyway.²

What the Presumption Does for You

The core legal mechanism is a pair of presumptions that fire automatically when someone breaks into your home. Wyoming law presumes you had a reasonable fear of imminent death or serious bodily injury, and it presumes the intruder entered intending to commit a violent act.¹

That matters because of what it saves you from having to prove. In an ordinary self-defense case, you have to show your fear was reasonable and that force was necessary. With the Castle Doctrine presumption in place, both of those elements are taken as given unless the state can affirmatively rebut them. You don’t need to articulate what frightened you or explain why you didn’t try something less violent first. The forced entry does that work.

What Triggers the Presumption

Two conditions have to be present together. The intruder must be entering (or in the process of entering) unlawfully and forcibly, and you must know or have reason to believe that unlawful forced entry is happening.¹

Force is doing a lot of work in that sentence. Someone who walks in through an unlocked door, without breaking or forcing anything, does not automatically trigger the presumption. You may still have a valid self-defense claim under the general standard, but the automatic Castle Doctrine advantage isn’t on the table.

The presumption also reaches a second scenario: when someone forcibly removes, or tries to forcibly remove, a person from the home against their will. Kidnappings and forced removals from a dwelling fall inside the doctrine, not just classic break-ins.

When the Presumption Does Not Apply

The statute carves out specific situations where the automatic presumption drops away. You may still argue general self-defense in these cases, but you lose the built-in legal advantage.

People with a legal right to be in the home — a co-owner, lessee, or titleholder — are outside the presumption. There is one important exception back the other way: if that person is subject to a domestic violence protective order or a pretrial no-contact order, the presumption applies against them even though they would otherwise be entitled to be there.¹
Custody situations are excluded. If the person you used force against has lawful custody or guardianship over the person being removed — a parent collecting their own child, for example — the presumption does not apply.
Peace officers and Wyoming Department of Corrections employees entering in the performance of official duties are excluded. This holds even for unannounced warrant entries. If you know or should know that the person coming through the door is law enforcement acting officially, the automatic presumption of reasonable fear is not available to you.¹

What Counts as a Home or Habitation

Wyoming defines these terms specifically for Castle Doctrine purposes in § 6-2-602(g).¹ A habitation is any structure designed or adapted for overnight accommodation. The statute lists buildings, modular units, trailers, campers, and tents. A home is any occupied residential dwelling place. Both definitions specifically exclude inmate housing in jails, state penal institutions, and contracted correctional facilities.

Some practical consequences follow. A camper, an RV, and a tent you’re sleeping in all count as habitations. An ordinary passenger car does not. It isn’t designed for overnight accommodation, and the statute doesn’t class standard vehicles as homes or habitations. If you’re attacked in your car, you still have no duty to retreat under the general self-defense rule, but you don’t get the automatic presumption of reasonable fear.

Wyoming courts have also refused to stretch the doctrine to outdoor areas around a dwelling. A driveway, a front yard, or a porch is not a “home” or “habitation” under § 6-2-602. Courts have rejected curtilage-style arguments that would extend the presumption to exterior space. A confrontation outside the walls of the dwelling runs under general self-defense and stand-your-ground, not under the Castle Doctrine’s automatic presumption.

No Duty to Retreat

Wyoming is a stand-your-ground state. Anywhere you have a legal right to be, you are not required to try to escape before defending yourself with reasonable force.¹ That covers your home, a parking lot, a sidewalk, anywhere lawful.

Two conditions limit it. You cannot be the initial aggressor, and you cannot be engaged in illegal activity at the time of the encounter.¹ Start the fight or provoke it, and the no-retreat rule is off the table. Commit a crime at the scene, and the protection falls away.

Criminal Immunity, Not Just a Defense

If your use of force was reasonable under § 6-2-602, Wyoming does not merely give you a defense to raise at trial. It bars criminal prosecution entirely.¹ That difference is significant. An affirmative defense means you go to trial and argue justification; immunity means the case should not reach trial.

Law enforcement will still investigate. Officers examine the physical evidence of forced entry, interview witnesses, and reconstruct the scene. The statute prevents prosecution, not investigation. If the facts match the statute, prosecutors should decline to charge.

Civil Immunity and Attorney Fees

Section 6-1-204 handles the lawsuit side. If your use of force was reasonable under § 6-2-602, the intruder or their family cannot successfully sue you for the resulting injuries or death.²

If a suit does come, you can file a pretrial motion asserting immunity, and the court holds a hearing before trial. At that hearing, the burden sits on you to show by a preponderance of the evidence that your use of force was reasonable under § 6-2-602.² Preponderance means more likely than not — a lower bar than the criminal “beyond a reasonable doubt” standard, but the responsibility to establish the claim is still yours. If the court grants the motion, the lawsuit is dismissed before trial.

The provision has real teeth on costs. When the court finds you immune, the plaintiff pays your reasonable attorney fees, court costs, lost income, and all other expenses you incurred defending the suit.² A plaintiff who sues a lawful defender risks paying both sides’ legal bills if the immunity claim holds.
