These consequences are completely dependent on the details surrounding the situation. For example, a Class 1 misdemeanor can receive a simple jail and probation sentence for up to 6 months, and fines could be suspended if the defendant completes counseling, anger management, community service, or anything else the judge deems suitable. Those convicted at any level will lose the right to possess a firearm.
Regardless of the severity, it is important to understand that domestic violence charges are often accompanied by restraining orders, protective orders, or move-out orders. Any teachers, attorneys, law enforcement officers, military personnel, or medical professionals will suffer consequences in their career.
