‘No stranger to big money matrimonial finance cases, Harry Oliver regularly handles matters generally involving assets between £10 million and £100 million. He was junior counsel in one of the largest cases ever when he acted for Del Monte Chief Vivian Imerman in his divorce from the sister of Robbie and Vincent Tchenguiz. Total assets in the case amounted to more than £300 million. Just as well then that Oliver is ‘a master of paperwork and figures,’ who has ‘a keen tactical brain.’ When he is instructed ‘clients feel that they are being represented by the very best counsel.’
