Accident and Lack of Intent as a Defense to Domestic Assault in Michigan

Domestic assault in Michigan requires intent. Under the model jury instruction, a battery is a touching that "must have been intended by the defendant, that is, not accidental," and "an assault cannot happen by accident."^[1] If contact was truly unintended, an element of the crime is missing, and it is the prosecutor who must prove intent beyond a reasonable doubt.^[3]

This page explains what kind of intent the law requires, what the accident instruction says, how intent is proved and contested, and where the accident defense stops.

What "intent" means in an assault case

The domestic assault instruction, M Crim JI 17.2a, describes two ways of committing the offense.^[1]

• Assault and battery. A battery is the forceful, violent or offensive touching of a person or something closely connected with him or her. The touching must have been intended by the defendant and must have been against the other person's will.^[1]
• Assault. An assault is an attempt to commit a battery, or an act that would cause a reasonable person to fear or apprehend an immediate battery. The defendant must have intended either to commit a battery or to make the other person reasonably fear an immediate battery.^[1]

The Use Note to that instruction states that all assaults are specific intent crimes, citing People v Johnson, a 1979 Michigan Supreme Court decision.^[2] In plain terms, it is not enough that the defendant's movement caused contact. The prosecutor has to show the defendant meant to make the contact, or meant to put the other person in fear of it.^[1]

The difference between the two forms is covered in Assault vs. battery in Michigan, and the offense as a whole in Domestic assault under MCL 750.81.

The accident instruction

Michigan has a model instruction for exactly this situation, M Crim JI 7.3a, titled "Accident as Defense to Specific Intent Crime." It tells jurors: "The defendant says that [his / her] conduct was accidental. If the defendant did not intend to [state specific intent required], [he / she] is not guilty. The prosecutor must prove beyond a reasonable doubt that the defendant intended to [state specific intent required]."^[3]

Two things follow from that wording.

1. Accident is not a defense the accused has to establish. It is a way of saying the prosecutor has not proved intent, and the burden never moves to the defendant.^[3][7]
2. The jury does not have to be sure it was an accident. The question is whether the prosecutor has proved intent beyond a reasonable doubt, which jurors are told means proof that leaves them firmly convinced.^[8]

Intent to touch is not intent to injure

A common misunderstanding is "I never meant to hurt anyone." That may be true and still not be a defense. The instructions require that the touching was intended, not that harm was intended. For a battery, "it does not matter whether the touching caused an injury," and an assault does not have to cause an actual injury.^[4][9]

What the defendant says	How the instructions treat it
"I turned around and my elbow caught her. I did not know she was behind me."	A claim that the touching itself was not intended. The prosecutor must prove beyond a reasonable doubt that it was.[1][3]
"I grabbed his wrist to get my phone back. I did not mean to leave a bruise."	The touching was intended. Whether it caused an injury does not matter to the battery element.[4]
"I threw the remote at the wall, not at her."	The question is whether the defendant intended to commit a battery or to make her reasonably fear an immediate battery.[1]
"I pushed him away because he was coming at me."	This is not accident. It is a claim of justification, decided under the self-defense rules.[10][11]

One more situation: the wrong person is struck. If the defendant intended to assault one person but by mistake or accident assaulted another, the crime is the same as if the first person had actually been assaulted.^[12] "I was not aiming at her" is therefore not an accident defense if the defendant was aiming at someone.

The last row of the table matters because the two theories pull in different directions: accident says "I did not mean to," and self-defense says "I meant to, and I was entitled to." See Self-defense under Michigan law.

An unintended injury can affect the level of the charge. Aggravated domestic assault requires proof that the assault caused a serious or aggravated injury.^[13] The statute describes that offense as one committed without intending to commit murder or to inflict great bodily harm less than murder.^[14] See Aggravated domestic assault and Can you be charged without an injury?

How intent is proved and contested

Nobody can see into another person's mind, so intent is decided from the surrounding evidence. Jurors may be told that intent may be proved by what the defendant said, what the defendant did, how he or she did it, or by any other facts and circumstances in evidence.^[15] In a domestic case, the evidence on both sides of that question typically includes:

• The 911 call and statements at the scene. What each person said in the first minutes may bear on how the contact happened. See 911 calls as evidence.
• Photographs and medical records. The location and pattern of an injury may fit one account better than the other. Photographs may be used to corroborate a witness's testimony.^[16]
• Other acts. Under MRE 404(b), evidence of other acts cannot be used to show character, but may be admitted for another purpose such as proving intent, absence of mistake or lack of accident.^[17] In a domestic violence prosecution, a separate statute, MCL 768.27b, allows evidence of the defendant's other acts of domestic violence for any purpose for which it is relevant, subject to MRE 403.^[18]
• The defendant's own account. A defendant has an absolute right not to testify, and the jury may not consider that choice.^[19] A defendant who wants jurors to hear a first-hand explanation of an accident has to weigh that right against testifying.

Prior-acts evidence deserves attention in an accident case. A claim of accident puts intent squarely in dispute, which is one of the purposes for which other-acts evidence is offered.^[17] Jurors are told that before they may consider such evidence they must first find that the defendant actually committed the other acts, and that they must not convict solely because they think the defendant is guilty of other bad conduct.^[20] The rules and notice deadlines are in Prior acts of domestic violence under MCL 768.27b.

What does not negate intent

Alcohol and drugs

MCL 768.37 took effect on September 1, 2002, and the Michigan Supreme Court has described it as having abolished the defense of voluntary intoxication except in one narrow circumstance.^[21][22] Under MCL 768.37 it is not a defense to any crime that the defendant was under the influence of voluntarily and knowingly consumed alcohol or drugs.^[5][21] The single exception involves an unforeseeable reaction to a legally obtained and properly used medication.^[6] See Alcohol, drugs and the "I was drunk" question.

Anger or loss of temper

The domestic assault instruction lists no exception for anger, provocation by words, or "I just snapped." The element is satisfied by an intent to make the contact or cause fear of it.^[1]

Mental condition and intent: the 2026 change

From 2001 to 2026, Michigan courts did not admit evidence of a mental condition short of legal insanity to negate specific intent. The Michigan Supreme Court overruled that rule in People v Madison on July 31, 2026, holding that the legal-insanity statute does not foreclose diminished-capacity evidence offered to contest the mental element of a specific-intent crime.^[23][24]

The ruling is about evidence. The Court reasoned that diminished capacity is distinct from the affirmative defense of legal insanity, which the defendant must prove, so the insanity statute has no bearing on whether diminished-capacity evidence is admissible.^[25][26] The sources reviewed for this guide do not show how Madison applies to an assault charge, what evidence is enough, or what jurors will be told. As of the August 31, 2026 edition of the model jury instructions, the committee had not adopted an instruction responding to Madison.^[24] A defendant who intends to introduce expert evidence relating to mental illness or intellectual disability bearing on specific intent must notify the prosecutor in writing, on a form approved by the state court administrator, not less than 30 days before the trial date or at another time the court directs.^[27]

Reckless conduct and children

Assault requires intent, but not every offense does. Fourth-degree child abuse can be committed by an omission or a reckless act that causes physical harm to a child.^[28] So an explanation that would answer an assault charge involving an adult may not answer a child abuse charge involving a child in the home. See Parental discipline and the line into assault.

If the jury is not convinced either way

The verdict follows the burden. If the evidence leaves a reasonable doubt about whether the contact was intended, the defendant is not guilty, because the prosecutor must prove each element beyond a reasonable doubt.^[7][3] And if the prosecution's evidence is insufficient to sustain a conviction, the court on the defendant's motion must direct a verdict of acquittal.^[29]
