Jane Farquharson called to the Bar of England and Wales in 1992. In London she built up a successful criminal practice, both prosecuting and defending with an emphasis on cases involving children and sexual offences. She also maintained a family practice specialising in children and public law matters.

Since qualifying in Scotland she has enjoyed a busy junior practice, being led in a number of high profile cases and appeals and appearing on her own in the High Court and Appeal Court. Her methodical approach has made her a first choice as junior counsel assisting senior in some of the most notorious cases of recent times.
