You can request a judgment debtor's exam with the court that the judgment was obtained in. You will have to file a Motion with the court. If you don't know how to draft a Motion or if the court does not have any forms, you may even be able to find an attorney to prepare the motion for you on a "unbundled" agreement for a small fee (I would guess $100-$200).
If you have any questions, feel free to contact me.
