How much time can a person get on a assault charge that is 10 years old ?

This depends on what kind of assault the person is charged with. The criminal history of the offender is another major factor the contributes to the amount of time they might get. We think that the statute of limitations might be have expired if it is a simple assault charge. Or, there are some assault charges (especially involving sex or against a minor) that will never expire and could bring a lifetime of imprisonment.
