I am not a judge and not even a lawyer, but I think I can help you out in your problem. I listed below the steps on how you can become a judge so you’ll have a reference in your study.
Become a lawyer – this means going to law school and passing the bar exam. A course in law is normally composed of an undergraduate degree and a Juris Doctor (J. D.) which you can secure after years of toiling in a refutable law school.
Pass the Bar exam – which is necessary to become a licensed lawyer. This requires you to take, and pass, to gain admission to the bar. You cannot practice law if you are not admitted to the bar first.
Work as a lawyer – to get the necessary experience and understanding of the law profession. This is very important because judges are required to pass judgment on complicated legal issues, act as referee among litigants, and oversee the management of his courtroom. Practicing law gives an aspiring judge firsthand experience on how courtrooms operate and how justice is administered.
Apply for the position – which maybe through an election or by submitting your application to a judicial nominating commission. It is also helpful if you know a lot of powerful politicians.
