How New York names and grades it
New York generally charges vandalism as criminal mischief, and the degree depends largely on the value of the damage claimed, so the same act can be a misdemeanor or a felony depending on the estimate. Graffiti is addressed by an offense of its own. The prosecution usually has to show that the damage was intentional or, in some degrees, reckless, and that you had no right to damage the property. Owning part of the property does not always prevent a charge, which is why arguments over a shared apartment or car can still lead to one. In domestic disputes, disabling a phone to stop someone from calling for help is treated seriously in its own right.
The estimate is often the real dispute
Because value drives the degree, the repair estimate deserves scrutiny. Estimates sometimes fold in earlier damage, upgrades, or full replacement where a repair would do, and the difference can move a case from one level to another. Keep your own photographs if you have them, and tell your lawyer what you know about the condition of the property before the incident. Do not contact the owner to negotiate payment yourself; offers made directly can be misunderstood or used as evidence, and any arrangement should go through counsel. If the incident was captured on video, identify where the cameras were so preservation can be requested before footage is overwritten.
How these cases often move
Many criminal mischief cases involve people with little or no record, and the discussion often centers on restitution and on whether the matter can be resolved without a lasting conviction. Whether that is realistic depends on the degree charged, the prosecutor's office, and your history. Students should raise any school disciplinary process, since it runs on its own track. In the initial meeting we look at the charge level, the support behind the damage figure, and whether a civil claim from the owner or an insurer is likely. We also flag any immigration or licensing consequence before a resolution is discussed.
