Assault vs battery in New Mexico
People use “assault” to mean a fight. New Mexico law does not. Here, assault and battery are two different crimes with two different statutes, and the difference matters when you read your charging paperwork.
Battery is the touch. Assault is the threat or the attempt. Add a weapon, a mask, a felony purpose or a serious injury and either one becomes “aggravated,” which is a felony. Add a spouse, partner or family member and it becomes a household-member charge with consequences of its own.
Assault (NMSA 1978, § 30-3-1)
Under NMSA 1978, § 30-3-1, assault is any of three things. One: trying to hit someone and missing. Two: a threat or move that makes someone reasonably believe they are about to be hit. Three: insulting words that attack someone’s honor or reputation. No contact is needed. Raising a fist, stepping toward someone with a bottle, or shouting a specific threat can each be charged. Assault is a petty misdemeanor.
Aggravated assault (NMSA 1978, § 30-3-2)
Aggravated assault New Mexico prosecutors charge under NMSA 1978, § 30-3-2 is an assault committed with a deadly weapon, while masked or disguised, or with intent to commit any felony. It is a fourth-degree felony. Whether an object counts as a “deadly weapon” can be the whole case.
Battery (NMSA 1978, § 30-3-4)
A battery charge in Las Cruces comes from NMSA 1978, § 30-3-4. The statute calls it an “unlawful, intentional touching or application of force to the person of another, when done in a rude, insolent or angry manner.” A push counts. Grabbing an arm counts. It does not require an injury. Simple battery is a petty misdemeanor.
Aggravated battery (NMSA 1978, § 30-3-5)
NMSA 1978, § 30-3-5 covers battery with intent to injure. It splits two ways. If the injury is “not likely to cause death or great bodily harm,” it is a misdemeanor. If it causes great bodily harm or is done with a deadly weapon, it is a third-degree felony. So is a battery done “in any manner whereby great bodily harm or death can be inflicted.” The same punch can land on either side of that line depending on how the state describes it.
Assault with intent to commit a violent felony
New Mexico also has a separate, more serious charge when an assault is made with intent to commit a violent felony. If that language appears on your paperwork, you are facing a separate, more serious charge and should call today.
Against a household member
If the other person is a spouse, former spouse, parent, co-parent, or someone you date or dated, the state will charge the household-member version instead. “Household member” is defined in NMSA 1978, § 30-3-11, and cohabitation is not required. Battery against a household member, {{DV_STATUTE}}, is a misdemeanor with mandatory offender treatment, and a conviction carries a federal firearm ban. Those cases are covered on the domestic violence attorney page.
Against a police officer or health care worker
Battery on a peace officer is charged under a separate statute with heavier penalties than ordinary battery; the exact class depends on how the state files it. New Mexico also has separate charges for battery on certain health care workers. If your paperwork names an officer, a jail guard, a nurse or a paramedic as the person touched, read the charging document and call. The defense starts with the body-camera footage.
Penalties
New Mexico sets sentences by class, not by crime. Two statutes do the work.
- Petty misdemeanor (assault, simple battery): up to six months in the county jail and a fine of up to $500, under NMSA 1978, § 31-19-1.
- Misdemeanor (aggravated battery without great bodily harm): up to 364 days in the county jail and a fine of up to $1,000, also under § 31-19-1.
- Fourth-degree felony (aggravated assault): a basic sentence of 18 months and a fine of up to $5,000, under NMSA 1978, § 31-18-15.
- Third-degree felony (aggravated battery with great bodily harm or a deadly weapon): a basic sentence of three years and a fine of up to $5,000, under § 31-18-15.
Those are the basic sentences. A judge can suspend or defer much of a sentence, meaning you serve it on probation instead of in jail. A prior record can increase it. A felony conviction also follows you into job applications, housing, professional licenses and firearm rights long after any sentence is done.
What happens next
Arrest or summons
Some assault cases start with handcuffs the same night. Others start with a summons in the mail weeks later, after an officer finishes the report. Either way, after a warrantless arrest a judge must find probable cause (enough evidence to make the charge reasonable) within 48 hours under Rule 5-301 NMRA, weekends included.
Arraignment
Misdemeanor and petty misdemeanor cases are heard in Doña Ana County Magistrate Court at 110 Calle de Alegra. If the charge is under city ordinance, they go to Las Cruces Municipal Court at 135 E. Griggs Ave. If you are not in custody, magistrate arraignment happens within 30 days of the complaint or the arrest, whichever is later, under Rule 6-506 NMRA.
Felonies go to the Third Judicial District Court at 201 W. Picacho Ave. Arraignment (your first court date, where the charge is read and you enter a plea) happens within 15 days of the formal charging paper, called an information or an indictment.
No-contact conditions
A release order in an assault or battery case can include a no-contact condition with the other person. If yours does, treat it as absolute. No texts, no messages through friends, no “just to apologize.” Violating it is a new charge and the fastest way to lose your release.
Preliminary hearing for felonies
If you are charged with a felony, the state must show probable cause at a preliminary examination or through a grand jury. Under Rule 5-302 NMRA, the preliminary examination is due within 10 days if you are in custody and 60 days if you are not. It is the first chance to question the officer and the person who made the report (the court calls them the complaining witness) under oath.
Trial
In magistrate court, trial must begin within 182 days of arraignment under Rule 6-506, or the case is dismissed with prejudice, which means it cannot be refiled. A case can end before trial by dismissal, by a plea to a lesser charge, or by a diversion agreement (a deal that drops the charge if you complete conditions). Whether any of those is possible depends on the facts. Some cases go to a jury. The decision is yours, made with the full picture in front of you.
How the defense works
Self-defense and defense of others under New Mexico law
New Mexico recognizes self-defense and defense of another person. In plain terms: you may use reasonable force to protect yourself or someone else from what looks like an immediate threat. The force you use has to fit the threat you face. If there is evidence to support it, the judge instructs the jury on self-defense and the state has to overcome it. The work is in building that evidence before anyone decides the charge.
Who started it: witnesses and video
An assault case can come down to one question: who started it. The police report answers it from one side. Kelly O’Connell Law uses a trained private investigator, a former homicide and narcotics officer, on all serious cases. The investigator finds the people who were standing nearby, interviews them while memories are fresh, and pulls surveillance, doorbell and phone video before it is overwritten. That record is what the defense is built on.
Injury severity and “great bodily harm”
The gap between a misdemeanor and a third-degree felony under § 30-3-5 is the phrase “great bodily harm.” Medical records, photographs and the timing of treatment all matter. An injury the state calls serious at charging can look different once the records are read closely.
Mutual combat and bar fights
Fights outside bars near New Mexico State University (NMSU) and elsewhere in Las Cruces end up in magistrate court. Officers can arrive after it is over, see one person bleeding, and arrest the other. Alcohol, crowds and bad lighting make every witness unreliable in a different way. These cases are built on video, timing and the full list of people involved, not on who talked first.
Reducing a felony to a misdemeanor
Where the facts allow, the goal is to move the case down the ladder: aggravated to simple, felony to misdemeanor, or a dismissal. If you have no prior felony, a conditional discharge under NMSA 1978, § 31-20-13 lets the court place you on probation without entering a conviction. If you are convicted of misdemeanor aggravated battery, you may later ask to have the record sealed under the Criminal Record Expungement Act, NMSA 1978, § 29-3A-1 et seq. You can file four years after the sentence ends, if there is no new conviction.

Frequently asked questions
What is the difference between assault and battery in New Mexico?
Battery is the touch. Under NMSA 1978, § 30-3-4 it is any unlawful, intentional touching or application of force done in a rude, insolent or angry manner. Assault is the threat or the attempt. Under § 30-3-1 it is an attempt to commit a battery, or conduct that makes someone reasonably believe a battery is about to happen. You can be charged with one, the other or both from the same incident. Both are petty misdemeanors in their basic form, and both become felonies when a weapon or serious injury is involved.
Is simple battery a felony in New Mexico?
No. Simple battery under § 30-3-4 is a petty misdemeanor, which means up to six months in the county jail and a fine of up to $500 under NMSA 1978, § 31-19-1. It becomes a felony when the state charges aggravated battery under § 30-3-5(C). That means great bodily harm, a deadly weapon, or an act done in a way that could cause great bodily harm or death. Battery against a household member is a separate charge with its own consequences, covered on the domestic violence attorney page.
What makes an assault "aggravated"?
Three things turn a petty-misdemeanor assault into aggravated assault under NMSA 1978, § 30-3-2: a deadly weapon, being masked or disguised, or acting with intent to commit any felony. Aggravated assault is a fourth-degree felony. The basic sentence is 18 months and a fine of up to $5,000. A "deadly weapon" does not have to be a gun or a knife. The state can argue that a bottle, a car or a tool counts. That argument can be contested.
Can I claim self-defense in a bar fight?
Sometimes, yes. New Mexico lets you use reasonable force to protect yourself or another person from what reasonably appears to be an immediate threat. The force has to fit the threat. The problem in bar fights is proof: the state may have one story, from the person who called 911. The defense needs the other story, which means finding the people who were standing there and the video that was rolling. The trained private investigator who works on all of Kelly O'Connell Law's serious cases does that work before footage is overwritten.
What is the penalty for battery on a police officer in New Mexico?
Battery on a peace officer is charged under a separate statute with heavier penalties than ordinary battery. The exact class depends on how the state files it, what injury is alleged and whether a weapon is claimed. Read the charging document and call. These cases turn on what the officer wrote in the report and what the body-camera footage shows. They also turn on whether the contact was intentional or part of an arrest that was already going badly.
Can assault charges be dropped if the other person does not want to press charges?
Not automatically. In New Mexico the case belongs to the state, not to the person who was hit or threatened. A prosecutor can go forward on the officer's report, photographs, 911 audio and other witnesses even if the person who made the report asks them to stop. (The court calls that person the complaining witness.) That said, a reluctant witness changes the practical strength of the case, and a lawyer can use that in negotiations or at trial. Do not contact the other person yourself to ask them to drop it; if there is a no-contact condition, that call is a new crime.
