Shadowing a barrister

You might be lucky but most only offer mini pupillage to over 18s due to confidentiality and the information you might be working with. Many only offer to those in second or third year of uni. There are some that offer first year uni but very few.

Have a look on Chambers, there’s some info but not a lot. If nothing there then it’s a case of finding chambers in your area and checking their individual websites.
