James Kessler QC listed in 'Chambers Global’ directory 2018

Chambers directory notes:  "James writes far and away the best book on the taxation of non-doms and is very widely respected because of that. He has built up a huge respect. He does not blow his own trumpet, and it's quite right that other people should blow it for him. He very much deserves his place." "He's the go-to man for advising on offshore taxation involving non-doms, not least because he's written a leading textbook on it."
James is head of Old Square Tax Chambers.
