‘Simply the best costs set in the country’, 4 New Square Chambers offers in-depth expertise at every level of call and across all aspects of costs and litigation funding, with particular areas of experience including wasted and non-party costs, funding arrangements, security for costs applications, and non-contentious advisory work. Nicholas Bacon KC, Robert Marven KC, Simon Teasdale and Stephen Innes all acted in Diag Human v Volterra Fietta, with this significant case about whether severance is available to save an otherwise enforceable conditional fee agreement heading from the Court of Appeal to the Supreme Court. In Northampton General Hospital NHS Trust v Luke Hoskin, Benjamin Williams KC, Roger Mallalieu KC and Pippa Manby appeared in a case which now progresses to the Court of Appeal to clarify the principle concerning recoverability of agency fees in personal injury claims. Marven KC also appeared on the opposite side to Mallalieu KC and Teasdale in Thomson Snell & Passmore LLP v Kenig, a Court of Appeal case concerning if a beneficiary to a will can later challenge solicitors’ costs even though they have been agreed and paid by the executor.
