James Kirby

"James is extremely concise and has a great ability to distil the law into user-friendly advice. He has considered judgement and inspires confidence."
(Legal 500 2024)

James Kirby is a Chancery barrister with a practice focused on Trusts and Estates (contentious and non-contentious), Court of Protection and Private Client Tax.

He is ranked by Legal 500 2024 as a ‘Rising Star’ in Private Client: Trusts and Probate.

James’s expertise as advocate may be seen from his successful defence of a probate claim at trial on the basis that the claim had been brought with undue delay: James v Scudamore [2023] Ch 391. This is now the leading case on delay in probate claims.

He is also an experienced junior counsel in heavy trusts and estates disputes and tax litigation. Reported cases include Hinduja v Hinduja [2020] 4 WLR 93, BCM Cayman Ltd v HMRC [2023] STC 1738 and HMRC v BlueCrest Capital Management LP [2023] EWCA Civ 1481.

James was appointed to the Attorney General’s C Panel in 2023. He is also an editor of Williams on Wills (11th edition, 2021).

Before becoming a barrister, James was a Fellow in History at Trinity College, Cambridge.


Partnerships & LLPs

James has experience of advising on partnership and LLP law, especially in relation to trusts and estates.

He has also acted as junior counsel in LLP tax cases, including BCM Cayman Ltd v HMRC [2023] STC 1738, HMRC v BlueCrest Capital Management LP [2023] EWCA Civ 1481, HFFX LLP v HMRC [2023] STC 678 and Odey Asset Management LLP v HMRC [2021] UKFTT 31 (TC). These appeals raise significant points of partnership/LLP law concerning profit allocations and the nature of a member’s interest in an LLP.
