My husband was charged with trespassing in a house owned by a bank.
It is likely he is being charged with First Degree Criminal Trespass, as he is being accused of trespassing inside a building. The maximum penalty is one year in jail, a $5,000 fine and two years probation. If the prosecutors believe he was intending to commit another crime while inside, he could be charged with the class C felony of Second Degree Burglary, which carries a standard sentencing range of up to 90 days in jail (assuming this is his first felony).
Regardless of whether he is being charged with a misdemeanor or felony, he needs to retain an experienced criminal defense attorney right away.
Criminal trespass is when you enter someone's property without authorization, either at a prohibited time or onto property you are not allowed to enter at all.
Sentencing is the process after criminal conviction in which the judge determines your punishment, such as jail or prison time, community service, and/or fines.
