If you have a problem, the best place to have it fixed is at its source (the lender, settlement agent, broker, etc.) If that approach fails and you think you have suffered because of a violation of federal law, you may be entitled to sue in a federal or state court. This is a matter you should discuss with your attorney. The National Credit Union Administration (NCUA) is the regulator and primary enforcement authority for federal credit unions.
