Given the proper circumstances, a judgment creditor can lien a judgment debtor's intellectual property rights owned in a copyrighted song or piece of literature where any royalties would then be subject to the levy by the judgment creditor.Most states have statutes allowing for the levy by a judgment creditor on a judgment debtor's personal property such as the item that you have written about. For more assistance, I suggest that you consult with an attorney that practices in the area of collection law.
