Take a vocational course. In learning to judge in the UK you will need to use a "Bar Professional Course" in learning for 1 full year or 2 a year and a half, to stand a chance of making it in the judiciary. To be considered as a judge you have to have a minimum of seven years’ experience as a barrister or solicitor, although the specifications depending on the type of law you practice vary considerably. All this depends on the decision of the Lord Chancellor.But if your name is mentioned, you're halfway to becoming a judge.
