Where a fine fits
A sentence after an assault conviction can include a fine, but courts also consider jail, probation, a conditional discharge, and orders of protection, and a fine is often combined with one of those. New York adds mandatory surcharges and fees to most convictions, so the amount owed is usually higher than the fine itself. Some assault cases are resolved with a plea to a lesser offense such as harassment in its lowest degree, which is a violation rather than a crime in New York, and the financial terms differ. Ranges depend on the level of the charge and are set by statute, which is why the specific charge matters more than any general figure you may read online.
Restitution and civil exposure are separate
Restitution compensates the injured person for losses such as medical bills and lost wages, and it is distinct from a fine paid to the state. It can be ordered as part of the sentence, and failing to pay can bring further consequences. A criminal resolution also does not close off a civil lawsuit, so the other person may still seek damages in a different court. Gather documents about your income and obligations, since ability to pay can become relevant when financial terms are discussed. Do not offer money directly to the complainant; any payment should run through counsel and the court.
Costs that never appear on a receipt
A conviction for assault can affect employment, professional licensing, housing applications, firearm licensing, and immigration status, and those effects often outweigh any fine. A violation such as harassment generally carries less weight than a misdemeanor or felony, but even that should be checked against your particular circumstances. In an early conversation we look at the exact charge, which resolution paths exist, and which collateral effects matter most to you before any money terms are discussed.
