Described in Chambers & Partners as “an unsurpassed advocate at the Chancery Bar”, Gilead has appeared in many high-profile cases in recent years, both in the UK and abroad. He receives praise for “his ability ‘to pull rabbits out of hats’ in fiendishly difficult cases” (HNW Guide 2016), and is consistently recommended in the major legal directories. The recent Chambers 2019 edition ranks him in Band 1 for both Traditional Chancery and Trusts and in Band 2 for Offshore and Art and Cultural Property. “He’s a trial barrister. He is a supergun you bring out for the cases where you really want to get on with matters.” The Legal 500 describes him as “a genius and a great strategist”, commenting that he is “fast becoming one of the most sought-after senior Chancery practitioners”. He was described by Who’s Who Legal 2018 as “one of the top silks in our research this year”, and is one of five silks in the “Most Highly Regarded” category. He is also featured in Legal Week’s Private Client Global Elite, and was the winner of the Antiquities Law Barrister of the Year Award in the Lawyer Monthly Legal Awards 2016.

Philippe Pulfer heads the Geneva Private Client practice. He is widely recognised as one of Switzerland’s leading private client lawyers and, for nearly 20 years, has been constantly top-ranked by all major professional directories. He is one of only two Swiss private client lawyers ranked in Chambers Global and has been described by Legal 500 as 'one of the most knowledgeable trust and private client practitioners in Switzerland'. He has been included in the Legal Week Private Client Global Elite since the ranking’s inaugural edition in 2012.


"Adam Streisand is widely regarded as one of the nation's top trial attorneys, particularly in high profile litigation involving private wealth disputes, fiduciary litigation, business succession and partnership disputes and litigation involving trusts, estates and conservatorships" (Los Angeles Business Journal, "Top Litigators", August 13, 2018). Mr. Streisand is best known for his victories in courtroom battles over celebrity estates and, as Bill Plaschke of the Los Angeles Times wrote: "Streisand was the lawyer who … rescued both local NBA teams." Mr. Streisand’s trial victory for former Microsoft CEO Steve Ballmer against Donald Sterling resulted in Ballmer’s $2 billion purchase of the Los Angeles Clippers. But, as the Los Angeles Daily Journal explained, what captured the legal world completely by surprise was his "particularly adept legal gambit involving a rarely invoked clause of California’s probate code" that made it all happen. As the Los Angeles Times noted, two years later, “Adam Streisand carried the future of the Lakers into Room 629 at the Stanley Mosk Courthouse in downtown Los Angeles. The veteran attorney is no stranger to high profile cases…. In a very real way, he [was] being asked to save the Lakers." As ESPN reported, “Jeanie Buss and her lawyer Adam Streisand won a decisive legal victory to prevent a coup attempt.”
