The accolade was bestowed at the British Legal Awards organised by Legal Week.
Aiming to celebrate achievement, excellence and innovation in the legal industry, the awards ceremony was staged in London at Old Billingsgate Market last week and hosted by comedian Dara O’Briain.
Daniel Birtwistle, managing partner of Mourant Ozannes’ Jersey office said: ‘With the strong links between Jersey and the City of London, being recognised at the British Legal Awards as the Offshore Law Firm of the Year is an important achievement for the firm.’
