Hello Hot Chocolate,
I recommed the first place you look is the Career Path page to see which route into law you would like to take.
I presume you would like to go to university and study law?
If so then you will need to apply for a university through UCAS - the Universities and Colleges Admissions Service - http://www.ucas.com
In order to choose an appropriate university it is advisible to take a look at our LLB directory. The Guardian and the Times University Guides are also useful points of reference.
I hope that helps and if you have any other questions please let me know.
