Defenses to a Domestic Violence Charge in Michigan: An Overview

Michigan law recognizes several defenses to a domestic assault charge, and they fall into two groups. Some say the prosecutor has not proved an element of the crime, such as intent or the domestic relationship.^[5][9] Others say the act was legally justified, as with self-defense.^[2]

This page is a map. It describes each defense in a few lines, says who has to prove what, and links to the guide that covers it in depth. It also lists the claims people often expect to be defenses that Michigan law does not treat as defenses. A defense is a legal argument about the evidence; raising one is not an accusation against anyone, and whether a defense fits a particular case depends on facts this page cannot know.

Where every defense starts: the prosecutor's burden

The defendant is presumed innocent. The prosecutor must prove each element of the crime beyond a reasonable doubt, and the defendant is not required to prove innocence or to do anything.^[1] Jurors are told that proof beyond a reasonable doubt is proof that leaves them firmly convinced of the defendant's guilt, and that a reasonable doubt is a fair, honest doubt growing out of the evidence or lack of evidence.^[10]

For domestic assault under MCL 750.81(2), the model jury instruction lists two elements.^[11]

1. The defendant assaulted, or assaulted and battered, the complaining witness. A battery is a forceful, violent or offensive touching that was intended and was against the other person's will; an assault is an attempt to commit a battery or an act that would cause a reasonable person to fear an immediate battery.^[5]
2. At the time, the complaining witness was the defendant's spouse or former spouse, had a child in common with the defendant, was a resident or former resident of the same household, or was a person with whom the defendant had or previously had a dating relationship.^[12]

Aggravated domestic assault adds a third element: that the assault caused a serious or aggravated injury.^[13] The elements are explained in Domestic assault under MCL 750.81.

A defendant has an absolute right not to testify, and jurors are told not to consider that choice.^[14] If the prosecution's evidence is insufficient to sustain a conviction, the court on the defendant's motion must direct a verdict of acquittal.^[15]

The defenses at a glance

Defense	What it says	Who has to prove what
Self-defense	The force was used to protect against the imminent unlawful use of force by the other person.	After some evidence is produced, the prosecutor must prove beyond a reasonable doubt that the defendant did not act in self-defense.[3][4][16]
Defense of others	The force was used to protect another person, such as a child.	The same non-deadly force instruction covers self-defense and defense of others.[2][16]
Accident or lack of intent	The contact was not intended.	The prosecutor must prove the required intent beyond a reasonable doubt.[6]
No qualifying relationship	The two people were not in one of the relationships the statute lists.	The relationship is an element the prosecutor must prove beyond a reasonable doubt.[9]
Consent to the touching	The touching was not against the other person's will.	"Against the will" is part of the definition of battery in the model instruction.[5][17] No source reviewed for this guide says that agreeing to a fight is a defense to an assault.[18]
Parental discipline	A parent used reasonable force to discipline a child.	Written into the child abuse statute; when it is raised, the prosecutor must prove beyond a reasonable doubt that the force was not reasonable as discipline.[19][20] The sources reviewed do not say whether it can be raised against an assault charge under MCL 750.81.[21][22]
Alibi	The defendant was somewhere else.	The prosecutor must prove beyond a reasonable doubt that the defendant was actually there.[23]
Medication exception	An unforeseeable reaction to a legally obtained, properly used medication prevented the defendant from forming the required intent.	An affirmative defense; the defendant has the burden of proof by a preponderance of the evidence.[8]

Defenses about the facts

A case can turn on what happened rather than on a named legal defense. The defense position may be that the event did not occur as described, that the account changed over time, or that the physical evidence does not match it. Those are challenges to the prosecutor's proof, not separate doctrines. A witness may be cross-examined on any matter relevant to credibility.^[24] The tools courts use to test an account, including cross-examination, prior inconsistent statements and corroboration, are covered in False accusations: how credibility is tested in court and in Evidence used in Michigan domestic violence cases.

Mental state defenses

The model instructions state that all assaults are specific intent crimes: the defendant must have intended to commit a battery or to make the other person reasonably fear an immediate battery.^[25] Three mental-state questions follow from that.

• Intoxication. 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.^[7]
• Diminished capacity. From 2001 until 2026, Michigan did not allow evidence of mental incapacity short of legal insanity to negate specific intent. On July 31, 2026, the Michigan Supreme Court overruled that rule in People v Madison.^[26][27] The ruling concerns the admissibility of evidence offered to contest intent; the sources reviewed do not show how it applies to an assault charge.^[28] As of the August 31, 2026 edition of the model jury instructions, no replacement instruction had been adopted.^[27]
• Insanity. Legal insanity is an affirmative defense that the defendant must prove by a preponderance of the evidence.^[29] A defendant who intends to assert insanity must give written notice not less than 30 days before trial, or at another time the court directs.^[30]

Challenges to how the evidence was gathered

A motion to suppress asks the court to keep out evidence obtained in violation of the defendant's rights, such as a statement taken during custodial interrogation without Miranda warnings.^[31] It is not a defense to the charge in the usual sense, because the case can continue on other evidence, but it can change what the jury hears. See Motions to suppress evidence.

What is not a defense in Michigan

• "I was drunk." Voluntary intoxication is not a defense to any crime. MCL 768.37 has applied to crimes committed on or after September 1, 2002.^[7][32]
• "There were no injuries." An assault does not have to cause an actual injury.^[33]
• "The other person does not want to prosecute." The prosecutor alone decides whether to prosecute.^[34] See Can the victim drop the charges?
• "The police never read me my rights." Miranda warnings are required only for custodial interrogation, and the consequence of a violation is that the statement cannot be used, not that the charge is dismissed.^[35][31]
• "We were both fighting." Michigan's model jury instructions contain no "mutual combat" instruction.^[18] The closest rule is that a willing participant in an altercation is not foreclosed from asserting self-defense but must take advantage of any ability to retreat.^[36]
• "The earlier case involved someone else." For the repeat-offender penalties, there is no requirement that the earlier conviction involved the same person.^[37]

Lesser offenses

A trial does not always end in "guilty as charged" or "not guilty." A requested instruction on a necessarily included lesser offense is proper if the greater offense requires the jury to find a disputed factual element that is not part of the lesser offense and a rational view of the evidence supports it.^[38] The domestic assault instruction is itself written so that it can be given as a less serious alternative to a greater charge.^[39]

How a defense is chosen

Defenses can conflict. A person who says "it was an accident" is saying something different from a person who says "I pushed back to protect myself." Which theory fits depends on the police report, the recordings, the photographs and what each witness is expected to say, which is why the first step is usually to obtain the discovery material. On request, the prosecutor must provide police reports, the defendant's recorded statements and any exculpatory information.^[40] See Discovery in Michigan domestic violence cases, and for the decision between negotiating and going to trial, Plea or trial: how to decide.
