Domestic Assault in the Fourth Degree in Missouri
Fourth-Degree Domestic Assault in Missouri Is a Misdemeanor — But Don't Treat It Like Nothing
Even a class A misdemeanor can mean up to a year in jail, fines, and a domestic violence record that affects your future.
Domestic assault in the fourth degree is Missouri’s lowest-level domestic violence charge — but it still carries up to one year in jail, a permanent federal firearms prohibition, and a no-expungement bar that lasts for life. It is also the charge most commonly filed after a domestic disturbance call where injuries are minor or absent.
What Is Domestic Assault in the Fourth Degree?
Under RSMo § 565.076, a person commits domestic assault in the fourth degree when they commit any of the following acts against a domestic victim:
- Recklessly cause physical pain or injury, OR
- Cause physical injury through criminal negligence by means of a firearm, OR
- Purposely place the domestic victim in apprehension of immediate physical injury, OR
- Recklessly create a substantial risk of death or serious physical injury, OR
- Cause offensive physical contact with the domestic victim, knowing it will be offensive, OR
- Isolate the domestic victim by restricting or limiting their access to other persons, telecommunication devices, or transportation¹
The sixth subsection — isolation — is unique to domestic assault. No equivalent provision exists in the general assault statutes. It means that controlling or restricting a domestic partner’s ability to communicate or move independently can be criminally charged under § 565.076 without any physical contact at all.
Fourth-Degree Domestic Assault Is the Most Common Charge — And the Most Frequently Defended Successfully
The Isolation Provision — What It Covers
The isolation subsection of § 565.076 criminalizes conduct that would not be charged under any other Missouri criminal statute.¹ A person who takes away a partner’s phone, prevents them from leaving the home, or controls their access to other people can face a Class A Misdemeanor domestic assault charge — even if no threatening words were spoken and no physical contact was made.
Courts interpret this provision in the context of domestic violence dynamics, where isolation is a recognized tool of coercive control. Defense attorneys challenge isolation charges on grounds that the conduct was consensual, that the restriction was temporary and safety-related, or that the accused lacked the required mental state.
Who is a “Domestic Victim”?
The domestic assault statutes apply when the alleged victim falls within the categories defined under § 565.002 and § 455.010, RSMo:²
- Current or former spouses
- Persons related by blood or marriage
- Current or former cohabitants
- Persons who share a child with the defendant, regardless of relationship history or cohabitation
- Persons in a current or former dating or intimate relationship
- Children of household or family members in any above category
Classification and Penalties
Base Classification — Class A Misdemeanor
Domestic assault in the fourth degree is a Class A Misdemeanor at base under RSMo § 565.076 — up to 1 year in jail and a fine of up to $2,000.¹ ³
Enhanced Classification — Class E Felony with Prior Conviction
If the defendant has any prior conviction for domestic assault in any degree, or for any assault offense, the charge automatically escalates to a Class E Felony — up to 4 years in prison.¹ This enhancement is mandatory — the prosecutor does not need to file additional charges or seek a separate finding. A single prior domestic assault or assault conviction at any level triggers felony classification on the next charge, regardless of how minor the new conduct was.
Under SB 888, signed by Governor Kehoe in April 2026, Class E felony convictions now carry a mandatory minimum of 25% of the sentence served before parole eligibility.⁴
| Classification | Circumstance | Sentence Range | 2026 Parole Min. |
|---|---|---|---|
| Class A Misdemeanor | No prior DV/assault conviction | Up to 1 year | N/A |
| Class E Felony (automatic) | Any prior DV or assault conviction | Up to 4 years | 25% |
The Federal Firearms Prohibition — Even for a Misdemeanor Conviction
This is the consequence that surprises most people charged with fourth-degree domestic assault.
Under 18 U.S.C. § 922(g)(9), any person convicted of a “misdemeanor crime of domestic violence” is permanently prohibited from possessing firearms under federal law — for life.⁵ Fourth-degree domestic assault under § 565.076 qualifies as a misdemeanor crime of domestic violence under the federal definition.
This prohibition is absolute. It covers:
- Ownership of any firearm
- Possession of any firearm in any form
- Purchasing or attempting to purchase a firearm
- Eligibility for a Missouri concealed carry permit
It applies immediately upon conviction. It cannot be removed by completing probation. It is not affected by a Missouri expungement, because Missouri expungement does not eliminate the underlying conviction for federal law purposes. For a client who owns firearms, hunts, holds a concealed carry permit, works in law enforcement or security, or serves in the military, a fourth-degree domestic assault misdemeanor conviction — the lowest possible domestic violence charge — can end a career and require surrender of all firearms permanently.
This is why fourth-degree domestic assault should never be treated as a minor charge to plead out quickly.
No Expungement — Ever
Like all domestic assault offenses, fourth-degree domestic assault is permanently ineligible for expungement under § 610.140(2), RSMo.⁶ This applies to the misdemeanor conviction — not just felony domestic assault. A fourth-degree domestic assault conviction will appear on every background check for the rest of the defendant’s life, regardless of the sentence imposed, regardless of rehabilitation, and regardless of how much time passes.
Protection Orders
An arrest for domestic assault in the fourth degree — even before any charges are filed in court — can trigger an ex parte protection order under Chapter 455, RSMo.⁷ An ex parte order is issued based solely on the petitioner’s written statement, without the defendant being present or notified. It can restrict where the defendant lives, prohibit contact with the victim and shared children, modify custody and visitation, and bar access to the family home — all before the criminal case has even begun.
Violation of a protection order is a separate criminal offense — Class A Misdemeanor for a first violation, escalating to Class E Felony for a second violation, and to Class D Felony when the violation involves physical assault or a prior domestic violence conviction.⁷
Defense Strategies for Fourth-Degree Domestic Assault
Challenging the Mental State — Reckless vs. Accidental
The most common conduct charged under § 565.076 involves reckless causation of physical pain. “Reckless” under Missouri law means consciously disregarding a substantial and unjustifiable risk.⁸ Conduct that was accidental, reflexive, or without awareness of the risk does not satisfy the recklessness standard. Defense attorneys challenge whether the evidence establishes the required mental state or whether the conduct was simply accidental.
Challenging the “Apprehension” Element
The third subsection — purposely placing the victim in apprehension of immediate physical injury — requires both a purposeful act and a genuine, reasonable fear of immediate injury. Defense attorneys challenge whether the alleged victim’s fear was reasonable under the circumstances, whether the threat was immediate, and whether the defendant’s conduct was purposefully directed at causing that apprehension.
Challenging the Isolation Charge
Isolation charges under the sixth subsection are highly fact-specific. Defense attorneys challenge whether the restriction was intentional and controlling rather than incidental, whether the alleged victim consented to or participated in the restriction, and whether the defendant’s conduct meets the statutory definition.
Self-Defense
Missouri’s self-defense law under § 563.031 applies in domestic situations.⁹ Conduct that is defensive in nature — responding to an aggressor’s physical threat — does not constitute domestic assault. Defense attorneys investigate who initiated the confrontation and whether the defendant’s conduct was protective rather than aggressive.
Avoiding the Conviction Entirely
For first-time offenders with no prior criminal history, diversion programs may be available — completing a domestic violence education program and remaining arrest-free in exchange for dismissal. An SIS (Suspended Imposition of Sentence) — where the court withholds entry of the conviction upon successful completion of probation — avoids the felony firearms prohibition and the expungement bar entirely, because no conviction is entered.
Negotiating to a Non-DV Disposition
A general assault fourth-degree charge (§ 565.056) or a peace disturbance (§ 574.010) at the misdemeanor level does not trigger the permanent federal firearms prohibition or the no-expungement bar. Defense attorneys negotiate non-domestic-violence dispositions in cases where the evidence does not strongly support the domestic victim element, where the relationship category is disputed, or where the collateral consequences of a domestic violence conviction would be particularly devastating for the client.
