Call the prosecutor on the case.
A felony requires a sentence that exceeds one year of jail time. A misdemeanor requires a sentence of 364 days or less.
It does not matter how long your husband was incarcerated. The sentence is what deterimines the crime's severity.
there is typically no fee to speak with the prosecutor, only to get copies of the court documents. S/he can explain the chartes, whether or not a plea occurred, and whether it's a misdemeanor or felony.
