What can we do to prevent jail time after my husband was caught with a gun as a felon?

He can be sentenced to the max of ten years, although highly unlikely. If he has not already hired a criminal defense attorney, he should. The attorney might be able to ask for a deferred adjudication. Your husband is not likely eligible for a straight probation. There are too many variables to account for with the limited information. You should consult with a local criminal defense attorney.
