Knowing what the words mean in Latin doesn't help you in any legal sense. You won't be able to present "at first sight evidence"(?!) in any useful manner without knowing the legal requirements and procedures. What you need to know is the law, and you're right, having that knowledge would help you when presenting a case....but that's a wholly different argument from knowing Latin.
