She has experience in international arbitration, litigation, mediation, expert determination and negotiated settlements. She works across a range of sectors and has particular expertise in hospitality and leisure, professional services, real estate, retail and automotive, in addition to infrastructure and capital projects.
Hannah has supported individuals, partnerships, companies, and central and local government with claims ranging from £50,000 to more than £100 million. She acts on behalf of claimants and defendants relating to claims arising from commercial and contractual disputes, business interruption and disturbance, and professional negligence.
She also regularly undertakes contentious business valuations in matters involving compulsory purchase, shareholder disputes and matrimonial proceedings.
Hannah’s recent work highlights include:
- Instructed by the group action claimants in a multi-million-pound failed property investment scheme. Hannah’s evidence was described by Mr Justice Foxton as “…thorough, measured and fair…” in reaching his conclusion that the defendants had acted fraudulently and dishonestly, and the investment schemes were unregulated collective investment schemes.
- Appointed by the joint administrators of an investment firm which had collapsed with allegations of fraudulent misrepresentations and operating fraudulently as a Ponzi scheme. The professional negligence claim was settled favourably for her clients in an out of court settlement.
- Co-authored of the Compulsory Purchase Association Mental Health Report 2025.
