Probably fine but I’d check what abbreviation they use (if you can find it through research).Is it ok if we use abbreviations for firms while writing cover letters or answers to questions... For instance, is it ok if we say "White & Case" once and then the subsequent ones employ the abbreviation "W&C", or do they mind?
Other examples, HL for Hogan Lovells, S&C for Sullivan & Cromwell, L&W for Latham & Watkins, etc..
For example Trowers & Hamlins seem to be ‘Trowers’ rather than T&H.
