LK Shields acted for UK investment group Smith & Williamson in relation to its merger with Dublin-based accountancy firm LHM Casey McGrath.

LHM Casey McGrath was founded in 2004 as an accountancy and financial services firm.
The combined entity will consist of a workforce of 135 people.
Smith & Williamson's Dublin Professional Services Managing Director, Paul Wyse, said "The team at LHM Casey McGrath is an excellent fit with our strategy in order to enable growth, improve our service offering and meet the needs of clients through a diverse range of professional services".
The LK Shields team was led by Managing Partner Emmet Scully, with assistance from Corporate Associates Lisa McEllin and James Byrne, Consultant Jennifer O'Neill and Trainee Solicitor Alice Pelissier.
