NY Penal Law 120.00: Charges, Penalties, Defenses & Protection Orders

New York Penal Law Section 120.00 defines assault in the third degree, the lowest-level assault offense in the state and a Class A misdemeanor. A conviction carries up to 364 days in jail and a fine of up to $1,000, plus mandatory surcharges and a criminal record. The statute reaches three different situations: intentionally injuring someone, recklessly injuring someone, and injuring someone through criminally negligent use of a deadly weapon or dangerous instrument.¹

The Three Ways You Can Be Charged

Which subsection the prosecutor picks matters, because each one requires proof of a different state of mind and each one opens up a different defense.

Intentional Injury

The first subsection applies when your conscious goal was to cause physical injury and injury actually resulted. The person hurt doesn’t have to be the person you aimed at. Swing at one person, hit a bystander, and the law transfers your intent to the person actually injured.¹

Reckless Injury

The second subsection drops the intent requirement entirely. It applies when you were aware of a serious risk of injuring someone and chose to ignore it. Throwing heavy objects off a balcony into a crowd is the textbook example. You didn’t want to hit anyone, but you knew the danger existed.¹

Criminal Negligence With a Weapon

The third subsection sits a step below recklessness. It applies when you failed to perceive a risk that a reasonable person would have seen, and the injury was caused by a deadly weapon or dangerous instrument. Bare hands and ordinary carelessness don’t fit here. The object matters: a loaded firearm, a switchblade, or metal knuckles count as deadly weapons by definition, while a bat, a bottle, or a car becomes a “dangerous instrument” based on how it was actually used.¹²

What Counts as “Physical Injury”

Every charge under Section 120.00 requires proof of physical injury, which New York defines as impairment of physical condition or substantial pain.² Courts draw a real line here. Bruises, swelling, cuts that need treatment, a black eye, a fractured finger, or an injury that kept someone home from work generally qualify. A shove that leaves no mark, a slap that stings for a moment, or redness that fades on its own usually does not.

Judges look at practical signals: whether the person went to a doctor, whether medication was prescribed, whether the injury interfered with daily activities. The alleged victim’s own description of pain carries weight, but a brief, passing sensation on its own rarely sustains a conviction. If the evidence of injury is thin, that alone can defeat the charge.

Penalties for a Conviction

As a Class A misdemeanor, third-degree assault carries a maximum jail sentence of 364 days. New York capped Class A misdemeanors at 364 days rather than a full year specifically because federal immigration law treats a potential sentence of one year or more as triggering harsher consequences.³

Instead of or in addition to jail, a judge can impose two or three years of probation. Probation means regular reporting to a probation officer and compliance with conditions such as no new arrests, stay-away provisions, anger management, or community service.⁴

The maximum fine is $1,000.⁵ On top of any fine, every misdemeanor conviction brings a mandatory surcharge of $175 and a $25 crime victim assistance fee, whether or not the judge fines you separately.⁶ The court can also order restitution covering the victim’s medical bills, lost wages, and other out-of-pocket losses.

Orders of Protection

Courts routinely issue orders of protection in assault cases, often at arraignment before any plea or conviction. A “full” order bars all contact with the alleged victim. A “limited” order allows peaceful contact but forbids threats or harassment. If you live with the complainant, a full stay-away order can lock you out of your home the same night you are arraigned.

The order can last through the pendency of the case, and if you are convicted it can extend through the full sentence, including probation. Violating one is a separate crime, and it stays a crime even if the protected person is the one who reached out to you.

Defenses That Actually Work

Self-Defense

New York law permits physical force to defend yourself or someone else when you reasonably believe it is necessary to prevent imminent unlawful force. “Reasonably” is doing the work in that sentence. Your own belief alone is not enough; a reasonable person in your position must also have perceived the threat.⁷

You cannot claim self-defense if you provoked the fight intending to injure the other person, or if you were the initial aggressor, unless you clearly withdrew and told the other person so and they kept coming anyway. New York imposes a duty to retreat before using deadly force, with one key exception: you have no duty to retreat inside your own home, as long as you were not the initial aggressor.⁷

No Physical Injury

If the contact caused nothing more than momentary discomfort or a brief redness, the charge should fail. Defense attorneys often attack the injury element by pointing out that the alleged victim never sought medical care, missed no work, and took no medication.

Wrong Mental State

Each subsection requires a specific state of mind, and the prosecution has to prove it beyond a reasonable doubt. An accidental contact with no recklessness or negligence does not fit any of the three. For the intentional charge, the defense may show the contact was inadvertent. For the reckless charge, the defense may show the defendant was genuinely unaware of the risk.

Common Off-Ramps: ACD and Attempted Assault

For a defendant with no prior record, the most attractive outcome is often an adjournment in contemplation of dismissal, or ACD. The case is adjourned without a date, and if you stay out of trouble for six months (one year in family offense cases), the charge is dismissed automatically and the record is sealed.⁸

An ACD is not a guilty plea and produces no conviction. But if you are arrested again or violate a condition during the waiting period, the prosecutor can restore the case and the original charge is back in play. Courts can attach conditions, including community service, dispute resolution, or a domestic violence education program.⁸ An ACD is not automatic, and prosecutors push back when injuries are significant or the defendant has any record.

Another common resolution is a plea down to attempted assault in the third degree, a Class B misdemeanor with a 90-day maximum. Defense attorneys often negotiate this reduction when the injury evidence is borderline.

Criminal Record and Sealing

A third-degree assault conviction creates a permanent criminal record that shows up on background checks for jobs, housing, and professional licenses. It flags violence to anyone reviewing it, which hits particularly hard in healthcare, education, childcare, and finance.

New York allows certain convictions to be sealed under CPL 160.59, but the gate is narrow. You must wait at least ten years after completing your sentence, including any probation. You can have no more than two convictions eligible for sealing, with no more than one felony among them, and no pending charges or later convictions.⁹ Sealing is not expungement. The record still exists and law enforcement can still see it, but it will not appear on most standard background checks.

Immigration Consequences

For non-citizens, a conviction under Section 120.00 can be worse than any jail sentence. Federal immigration law treats certain misdemeanors as crimes involving moral turpitude, which can make a non-citizen deportable after a single conviction when the offense carries a potential sentence of one year or more. New York’s 364-day cap was partly a response to this, but the protection is not absolute. Immigration courts look at both the statutory elements and the facts, and an assault conviction involving a domestic partner or family member creates additional grounds for removal. Any non-citizen charged under this statute should consult an immigration attorney alongside the criminal defense lawyer, because a plea that looks good in criminal court can still be devastating in immigration court.

Deadline to File the Charge

Prosecutors have two years from the date of the incident to file a misdemeanor assault charge. Once that window closes, the case cannot be brought, regardless of how strong the evidence is. The clock runs from the date of the alleged offense, not from the date of the police report or arrest.¹⁰
