Hannah Piper

Senior Associate

Hannah Piper

Hannah enjoys the law and thrives on constructing an argument, but she also recognizes that clients often prefer a commercial resolution to a legal one. As a senior associate in our financial services disputes team in London, Hannah knows the challenges that clients face in the financial services sector, and she works closely with banks, financial institutions and corporates to address them. She manages investigations ranging from the cross-border and regulator-driven to the domestic and internal.  

She brings and defends high value and complex High Court claims. She helps clients to minimize the risk of those investigations and proceedings arising in the first place. Whatever the issue, Hannah appreciates the need to be both reactive and proactive, finding workable solutions and identifying potential issues before they arise.

Hannah does not just practice civil procedure – she has first-hand experience of reforming it. She made an early contribution to the litigation landscape when, as a junior associate, she worked as Lord Justice Jackson's judicial assistant on his Review of Civil Litigation Costs. She helped him to write his Final Report and to begin implementing his recommendations, aimed at controlling costs and promoting access to justice.
