Jonathan Furness QC

Practice Overview

Jonathan Furness QC has earned a deserved first class reputation in all areas of children work and in respect of financial disputes arising from divorce. He has practiced in Cardiff since 1980 taking silk in 2003.

The Legal 500 states he has ‘an exceptional reputation for handling care cases involving violence’ whilst the 2011 edition of Chambers UK reports that he is ‘"blazing a trail in Cardiff" and is usually the first choice for high net worth ancillary relief cases'.

The advocacy skills he brings to each case are complemented by his thorough and detailed preparation and analysis. Throughout the process he remains approachable and sympathetic to clients, putting them at ease through difficult circumstances.

Jonathan acts for Local Authorities, CAFCASS, parents and directly for children. Although he now practices exclusively in family work, including some Care Standards work, he still sits in the Crown Court as a Recorder.

Also highly proficient in care cases and sensitive children's matters. Sources are quick to highlight his outstanding strategic skills and preparation.' "He is very thorough and makes everything very understandable. A fantastic advocate - first-class." "For complex financial cases he really is fantastic - he can deal with everything thrown at him." (Chambers UK 2016)

'Two of its strongest silks, Jonathan Furness QC and James Tillyard QC, are "both top-rate and comparable to the top London barristers."
