This can be difficult and I have represented a few clients in his situation. Generally, how long a person found to be contempt stays in jail is up to the discretion of the judge. Unfortunately, often times these matters fly under the court's radar. In other words, if you don't ask for a court date the court may not review the case for some time. In the past I have filed a Motion for Release and at the court date if you show the judge that the contempt party has no assets and is not willfully failing to pay then by law the court has to let him out. Hope this helps and good luck.
