If you’ve lost any money due to a fraudulent investment scheme, then yes, you should contact a lawyer immediately. They’ll explain how to recover investment losses and help you understand your rights as a victim of fraud. I recently invested funds into what turned out to be a Ponzi scheme but I was able to reclaim every single penny. It just takes a lot of work.
So to answer your question, get a lawyer involved if you think a crime has been committed. If you put money into legitimate investments and lost it legally, then lawyers unfortunately won’t be able to help. If it was a scam, however, then they have the right to look into the bank account of the dodgy money manager or whoever recommended them to you. If they find your money, they can recover it.
