Nasima trained at a Legal 500 regional firm and successfully completed her training contract in 2004. She is an experienced litigator with over 18 years’ experience. Nasima joined Thomson Snell & Passmore’s Dispute Resolution department in September 2021.

She advises on all aspects of estates and trust litigation including challenges to the validity of wills, applications for rectification and interpretation of testamentary documents, Inheritance Act claims, actions against trustee and executors including applications for accounts and removal and replacement of PRs, disputes between executors including applications in the administration process and disputes relating to the beneficial ownership of property.
