I'm lodging a form 4 minor case claim at the magistrates court of WA (civil jurisdiction) and having difficulty in identifying the most accurate defendant details. The business has recently changed abn numbers and was previously a family partnership, but now is a sole trader according to abn lookup. But on ASIC search the holders name is a pty ltd, and the type is a body corporate . So can someone please advise, do I use the original partnership at the time of purchase and list both individual parties trading as the company? Or do I just name the partner that is now a sole trader? Or can I just list him personally as an individual and not as a business? What's the best way to get my money back from this shyster through the courts under Australian Consumer Law?
