Domestic Assault Charges in Missouri

There are four degrees of domestic assault in Missouri: 

  • 1st degree:  attempting to kill or knowingly or attempting to cause serious physical injury to a domestic victim is first degree domestic assault.  The potential range of punishment is 5 to 15 years in prison if the crime does not result in physical injury to the victim.  If the conduct does result in serious physical injury, then it is a class A felony punishable by 10 to 30 years in prison or life in prison.
  • 2nd degree:  knowingly causing physical injury, recklessly causing serious physical injury, or recklessly causing physical injury with a dealy weapon to a domestic victim will result in a charge of second degree domestic assault, which is a class D felony punishable by up to 7 years in prison.
  • 3rd degree:  attempting to cause physical injury or knowingly causing pain or illness to a domestic victim is the class E felony of domestic assault in the third degree.  This offense is punishable by up to four years in the department of corrections.
  • 4th degree:  lesser conduct such as attempting to cause pain, negligently causing injury, placing someone in apprehension of injury, recklessly creating a substantial risk of serious physical injury, offensive contact, and isolation committed against a domestic victim will lead to a charge of domestic assault in the fourth degree, which is normally a class A misdemeanor with a potential for a one year jail sentence and up to a $2,000 fine. 

A convicted domestic assaulter may also be required to pay restitution, which means reimbursement to the victim to cover the cost of medical bills, counselling, etc.


There are also collateral consequences to being convicted of domestic assault: if you are found guilty of any level of domestic assault, federal law will prohibit you from possessing or purchasing a firearm. With the significant potential sentences that can be imposed, and the collateral consequences, it is important to hire an attorney who has the experience to fight for you if you have been charged with domestic assault.  

Armed Criminal Action Charges in Missouri

If a person commits an assault or another felony while using a deadly weapon, then they can be charged with an armed criminal action in addition to anything else that they are charged with. Armed criminal action in Missouri (ACA) is committed by any person who “commits any felony under the laws of this state by, with, or through the use, assistance, or aid of a dangerous instrument or deadly weapon”.


Armed criminal action charges vary depending on how many times the convicted person has been convicted of an ACA. First time offenders will be charged with 3-15 years in prison (unless they use a firearm that they obtained illegally, in which case the minimum sentence is 5 years). Second time offenders will be charged 5-30 years in prison. Third and subsequent offenders will be charged with a minimum of 10 years in prison and can be sentenced to up to life in prison.  Most significantly, the sentences for armed criminal action must run consecutive to other sentences, and there is a mandatory period of incarceration of at least three years before someone convicted is eligible for probation or parole.
