I would get this person in for a deposition in aid of enforcement of the judgment. This will force her to answer questions under oath, frequently in front of a judge or a master. You can ask her anything about her assets and her income. She may have opened a new business. If this new business is similar to her old business, you may be able to sue the new business for successor liability.
Stay on top of her. Although she may someday file bankruptcy and get out from under your efforts, keeping the pressure up is likely the only way you'll get paid.Ask a similar question
