Liu v. Florida: Co-Occupant Rule, Presumption, and Immunity

Under Florida’s Castle Doctrine, a co-occupant situation gets the same no-retreat protection as any other home attack: if someone you live with attacks you in your own home, you have no duty to flee before using force, and you may use deadly force if you reasonably believe it is necessary to prevent imminent death, great bodily harm, or a forcible felony. What changes in a co-occupant case is the automatic presumption that your fear was reasonable. That presumption does not apply when the attacker also has a legal right to be in the home, unless a domestic violence injunction or no-contact order was already in place against them.

No Duty to Retreat From a Co-Occupant

Florida settled the co-occupant question in Weiand v. State, 732 So. 2d 1044 (1999), when the Florida Supreme Court held that a resident attacked at home by someone they live with has no duty to leave the residence before using deadly force in self-defense.¹ Weiand still imposed a limited duty to retreat within the home when it was safe to do so, but the 2005 Stand Your Ground statute, codified at Section 776.013, eliminated even that limited duty. A person lawfully in a dwelling may stand their ground and meet force with force.²

The threshold for deadly force is the same whether the attacker is a stranger or a spouse. You must reasonably believe deadly force is necessary to prevent imminent death, great bodily harm, or a forcible felony. Non-deadly force has a lower bar: you may use it whenever you reasonably believe it is necessary to defend against another person’s imminent use of unlawful force, again with no duty to retreat.³

Why the Presumption of Fear Is Different for Co-Occupants

Section 776.013 gives a powerful advantage to homeowners defending against intruders: when someone unlawfully and forcefully enters your dwelling, the law presumes you had a reasonable fear of imminent death or great bodily harm. That presumption shifts the work of disproving reasonable fear onto the prosecution.²

That presumption does not apply when the person you used force against also had a legal right to be in the dwelling. An owner, lessee, or titleholder who shares the home with you is not treated as an intruder for purposes of this automatic presumption, so a roommate, spouse, or partner attack does not trigger it on its own.²

One exception restores it. If an injunction for protection from domestic violence, or a written pretrial supervision order of no contact, was in place against the co-occupant, the presumption of fear comes back.² A protective order does more than draw a legal line; it changes the evidentiary posture of any later self-defense claim if the restrained person violates it.

What You Still Have to Show Without the Presumption

Losing the automatic presumption does not mean losing the right to self-defense. You still have no duty to retreat, and you can still claim justification. You simply have to show, under the facts, that your belief in imminent danger was reasonable.

Courts look at the totality of the circumstances: the relative size and strength of the people involved, whether anyone was armed, the history of violence between the parties, and who started the confrontation. Florida case law is firm that the Castle Doctrine does not protect someone who initiated the fight or lay in wait for the other person.⁴ Mutual combat is a particularly hard set of facts; a resident who shares equal responsibility for an escalating fight will not get the benefit of standing their ground.

When Castle Doctrine Protection Disappears

A few situations strip away the home-protection framework regardless of who the attacker is:

Stand Your Ground under Section 776.012 separately requires that the person using deadly force not be engaged in criminal activity and be in a place where they have a right to be.³

The Pre-Trial Immunity Hearing

Section 776.032 gives a person who used force as permitted by law immunity from criminal prosecution and civil suit. That immunity can be asserted before trial through a motion and an evidentiary hearing.⁵

At the hearing, the defense needs only to make a prima facie showing that self-defense applies. The burden then shifts to the prosecution, which must prove by clear and convincing evidence that the use of force was not justified.⁵ That standard sits above the usual civil threshold but below the reasonable-doubt standard that governs the trial itself. If the judge grants immunity, the charges are dismissed. If not, the case proceeds and the defendant may still argue self-defense to the jury.

In a co-occupant case without a protective order, you walk into that hearing without the presumption of fear, so the quality of your evidence matters more. Prior abuse history, injuries documented at the scene, 911 recordings, and witness accounts all do the work the presumption would otherwise do.

What a Failed Claim Costs

The stakes are the reason the evidentiary posture matters. Aggravated battery, which covers intentional infliction of great bodily harm or use of a deadly weapon, is a second-degree felony.⁶ Manslaughter is also a second-degree felony.⁷ A second-degree felony carries a maximum of 15 years in prison.⁸

Florida’s 10-20-Life law raises the floor sharply when a firearm is involved. Aggravated battery while possessing a firearm carries a 10-year mandatory minimum; discharging the firearm during the offense carries 20 years; and if the discharge causes death or great bodily harm, the mandatory minimum is 25 years to life.⁹ Judges cannot waive these minimums. A self-defense claim involving a gun fired in the home either succeeds or results in a lengthy mandatory sentence.

What Actually Decides Co-Occupant Cases

In practice, these cases turn on evidence of who was the aggressor and what the defender reasonably believed in the moment. The only direct witnesses are usually the two people in the fight, so physical evidence, 911 recordings, and the documented history between the parties carry the weight.

A documented pattern of abuse against you helps. Police reports, protective orders, medical records, and testimony from people who saw prior incidents all go to whether your belief in imminent danger was reasonable. Weiand itself turned significantly on expert testimony about battered spouse syndrome and the defendant’s history of being beaten and choked by her husband.¹

Calling 911 immediately matters for its own reasons. The recording captures your state of mind and your account of events before anyone has had time to shape a narrative around them. Delay, or leaving the scene without contacting police, is the behavior prosecutors point to when they argue a self-defense claim was constructed after the fact.
