What most people don’t know is that there is a difference between a lawyer and an attorney. To put it in a nutshell, you can be a lawyer and not an attorney but if you are an attorney you are also by default a lawyer.
Anyone who has studied law at law school or university can be called a lawyer. Even if they do not practice law or deal with lawsuits and courts, it would be correct to call them a lawyer. However, just because you have studied law does not mean that you are an attorney. Most lawyers who are not attorneys tend to be consultants or legal advisors but do not have authority to represent you in a court of law. A timeshare lawyer would be able to give you advice but nothing more.
Attorneys are lawyers who have sat bar exams and completed their practice in a specific area. Most timeshare attorneys do not deal with timeshare exclusively but are perhaps consumer rights attorneys that may take on a claim in case of breach of contract or a deliberate timeshare scam. In any case, if you are looking for someone to represent you in court, you must seek an attorney.
