Mousumi Chowdhury

Call 2014

Mousumi Chowdhury has a very busy practice in immigration, family and regulatory law and welcomes all instructions within her expertise. For certain firms, she is their preferred counsel in immigration and family matters.

Mousumi is also Direct Access accredited and is happy to take on cases from lay clients in suitable matters.

Described by a Partner and Head of the Regulatory team at Blake Morgan LLP, a leading 500 tier firm, as ‘impressive’, Mousumi is the ideal choice of counsel to instruct in the field of regulatory law.

Mousumi has recently completed a secondment to the litigation team at Eversheds Sutherland (International) LLP, acting as in-house counsel on the RL250 project.

Alongside her practice, Mousumi is also a Visiting Lecturer at Westminster University, delivering teaching on Child Protection Law and Policy and Family Law.


Mousumi has completed a secondment in a Tier 1 500 ranked large law firm acting on behalf of regulatory bodies. During this time, Mousumi was involved in a number of investigations and acted as an advocate before regulatory panels and in the High Court. She is the firm’s preferred counsel in interim order extension hearings in the High Court.

Mousumi is recognised as a determined and client focused advocate who specialises in advice, representation and advocacy in all areas of immigration, asylum, nationality and citizenship, bail, human trafficking, deportation, judicial review and detention cases. She is instructed to appear in courts and tribunals at all levels up to and including the Court of Appeal.

Described by one solicitor as ‘an extremely diligent advocate whose attention to detail is exemplary’ Mousumi’s ability to engage judges and opposing counsel in a respectful manner allied with the unwavering and tenacious nature of her advocacy has led to successes both at the First-tier Tribunal and Upper Tribunal Immigration and Asylum Chamber and makes her a clear choice for solicitors in challenging cases.

Mousumi is also committed to helping the most vulnerable in society and regularly volunteers with ‘Bail for Immigration Detainees’, a charity that provides pro bono representation at bail hearings.

Mousumi accepts instructions in all areas of family law, including: financial remedy proceedings, private children, non molestation and occupation order applications and care proceedings.

Mousumi’s knowledge of family law is further complemented by her role as a Visiting Lecturer at Westminster University, teaching the subject.

Solicitors and clients have described Mousumi as well-prepared, articulate and dedicated to ensuring a matter is resolved with the least number of hearings as possible. Mousumi is regularly instructed in fact-findings and final hearings. Mousumi’s previous experience of working with the National Centre of Domestic Violence has meant that she is particularly well-equipped to assist with vulnerable clients.
