Simple vs. Aggravated Assault in South Dakota: Timelines, Fines, and Jail Time

Current as of: October 2, 2026 Assault & Battery South Dakota
The difference between Simple and Aggravated Assault in South Dakota often comes down to the severity of the injury or the presence of a weapon. Simple Assault is a Class 1 misdemeanor, while Aggravated Assault is a Class 3 felony that can lead to 15 years in state prison.

Being charged with any level of assault in South Dakota is a life-altering event that threatens your freedom, your career, and your financial stability. Many people mistakenly believe that an assault charge only applies if you physically beat someone into a hospital bed. In reality, under South Dakota law, you can be convicted of assault simply for attempting to cause injury or intentionally making someone fear that they are about to be harmed.

Understanding the strict legal distinctions between a misdemeanor Simple Assault and a felony Aggravated Assault is crucial for anticipating your potential jail time, fines, and long-term consequences. Because the prosecution will aggressively pursue the highest possible charges, you can search our directory to find an experienced local criminal defense attorney who can fight to have your charges reduced or dismissed entirely.

Step-by-Step Process: From Arrest to Sentencing in South Dakota

Whether your case is handled at the Lincoln County Courthouse, Canton, or the Pennington County Courthouse, Rapid City, the state's criminal justice system follows a rigid statutory framework to categorize violent offenses.

Step 1: Understanding Simple Assault Charges

Under S.D. Codified Laws § 22-18-1, Simple Assault occurs if you attempt to cause bodily injury, recklessly cause bodily injury, or intentionally put another person in fear of imminent bodily harm. This covers a wide range of actions, from throwing a punch in a bar fight to shoving someone aggressively during an argument. It is generally classified as a Class 1 misdemeanor.

Step 2: The Legal Definition of 'Serious Bodily Injury'

The charge escalates to Aggravated Assault under S.D. Codified Laws § 22-18-1.1 if the victim suffers 'serious bodily injury.' In South Dakota courts, a simple black eye or a bruised arm is usually not enough. Serious bodily injury implies severe physical trauma, such as broken bones, deep lacerations requiring stitches, internal bleeding, or long-term loss of the function of an organ or limb. If the prosecutor can prove this level of harm occurred, you face a Class 3 felony.

Step 3: How Holding a Deadly Weapon Elevates the Charge

You do not even have to physically strike someone to be charged with a felony. Precedents like State v. Fender, 358 N.W.2d 248 (SD Supreme Court 1984) established that simply pointing a loaded firearm at someone, or brandishing a knife with the intent to cause them to fear imminent serious harm, constitutes Aggravated Assault. The presence of a deadly weapon automatically transforms a minor dispute into a major felony, regardless of whether any physical contact occurred or any blood was drawn.

Step 4: Timelines for Court Costs and Restitution

If you are convicted, the judge will not only impose punitive fines but also order restitution under S.D. Codified Laws § 23A-28-3. This means you will be legally required to pay for the victim's out-of-pocket medical bills, ambulance fees, and potentially lost wages. Restitution orders are strictly enforced by courts like the Minnehaha County Courthouse, Sioux Falls, and failing to pay on the court's designated timeline can result in a violation of your probation and immediate jail time.

How Much Are the Fines and Jail Time in South Dakota?

The potential penalties for assault in South Dakota vary massively based on the specific class of the crime you are convicted of.

  • Simple Assault (Class 1 Misdemeanor): Punishable by up to 1 year in a county jail and a maximum fine of $2,000.
  • Simple Assault (Domestic Violence): Carries similar baseline penalties but includes mandatory counseling, loss of firearm rights, and enhanced penalties for subsequent offenses.
  • Aggravated Assault (Class 3 Felony): Punishable by up to 15 years in the state penitentiary and a maximum fine of $30,000.
  • Aggravated Assault Against Law Enforcement: If the victim is a police officer, firefighter, or EMT acting in their official duties, the charge becomes a Class 2 felony, punishable by up to 25 years in prison and a $50,000 fine.

How Long Does a Criminal Assault Case Take?

A Simple Assault case might be concluded through a plea bargain or bench trial within 2 to 5 months. However, an Aggravated Assault case involving extensive medical records, expert witness testimonies, and a full jury trial will usually take 9 to 18 months to reach a final verdict. During this long timeline, you may be subject to strict bail conditions, travel restrictions, and no-contact orders.

Frequently Asked Questions (FAQ)

Can an assault charge be dropped if the victim refuses to testify?

Not necessarily. In South Dakota, the state prosecutor brings the charges, not the victim. If the prosecutor has other evidence, such as 911 recordings, security footage, or police observations, they can still proceed with the case without the victim's cooperation.

What is the difference between assault and battery?

Unlike some states that separate the two (assault being the threat, battery being the physical strike), South Dakota consolidates both physical violence and the threat of violence under the single legal definition of 'Assault.'

Can words alone constitute an assault?

Generally, no. Mere insults or threats of future harm do not constitute assault. There must be an overt physical act that causes the victim to reasonably fear immediate, imminent bodily harm.

Will an assault conviction affect my right to own a gun?

Yes. Any felony Aggravated Assault conviction, or a misdemeanor Simple Assault conviction that involves domestic violence, will permanently ban you from owning or possessing a firearm under both federal and state law.

Is it possible to reduce a felony assault to a misdemeanor?

Yes. An experienced defense attorney can often negotiate with the prosecutor to reduce an Aggravated Assault charge to Simple Assault, especially if the evidence of 'serious bodily injury' is weak or highly debatable.
