She leads the cross-departmental risk and regulatory team to deliver a seamless offering to clients with complex and varied needs: "I have found Nin to be an extremely approachable individual and very much someone that can be considered a ‘go to’ person when it comes to a myriad of questions that might require legal, regulatory, risk & governance consideration." Nin works closely with the Jersey based risk & regulatory team to ensure that clients with a presence across the Channel Islands are able to receive a blended Channel Islands service.

"I help clients through complex situations and, on occasion, tumultuous times in the most pragmatic, commercial and careful way."


Nin is known for her work in regulatory compliance and enforcement, financial crime, risk and governance. Clients rely on her skills, experience, calm manner and technical expertise to provide advice and guidance on complex legal matters with high risk factors and potentially devastating outcomes. "I have engaged Nin on a number of other issues that required expert legal advice. Nin is my go to resource when we need legal assistance with complex and high priority regulatory and risk related matters." She is trusted by her clients to provide accurate, commercial and time sensitive advice.

Nin has a strong sanctions practice that extends across transactional, advisory and contentious matters and is an expert in this legally complex and important developing area of practice. Nin has an established international network where clients require cross-jurisdictional sanctions advice.

Nin leads, and regularly presents at, an industry Risk & Regulatory forum created for leading individuals from a cross section of the finance sector to share information from a commercial and legal perspective, praised by one client as being "one of the most useful and progressive initiatives in the industry". Nin regularly speaks at local conferences, and writes, on regulatory matters.

Key matters in 2020 include:

  • Advising on client regulatory obligations in respect of a new target market involving complex structuring; and, developing an appropriate risk based compliance framework.
  • Representing individuals in a regulatory enforcement matter focused on a Guernsey fund.
  • Advising on a financial crime matter in respect of the determination of provenance of funds.
  • Engaged to provide expert advice on Alderney e-gaming in respect of ongoing proceedings in England.


On leaving school, Nin qualified as a nurse and worked in medical research in London.

She returned to Guernsey in 2002 where she spent 8 years within the banking division of the Guernsey Financial Services Commission. During this time she obtained a law degree from Nottingham Law School and completed the Legal Practice Course at the College of Law, Bloomsbury.

She joined Collas Crill as a trainee in 2010 and qualified into the dispute resolution team.


Nin is recommended by Chambers and Partners for her work on contentious regulatory matters. She is named as a 'Rising star' in the Legal 500 2022 guide.
