Year of Call: 1994 Silk: 2019

Aparna is a highly sought-after tax barrister.

Aparna’s transition into silk has been seamless: she continues to have high profile litigation and complex advisory work.

Clients value her excellent technical ability, approachability, commercial approach, her impressive advocacy and cross examination skills.

Aparna co-authors “McCutcheon on Inheritance Tax” and “Mellows on the Taxation of Trustees and Executors”.
