Northern Ireland’s legal market has historically been dominated by Belfast firms such as Carson McDowell , Tughans and Cleaver Fulton Rankin , as well as the Dublin firms with offices north of the border, such as Arthur Cox Belfast  and A&L Goodbody. In recent years, a succession of UK firms have launched bases in Belfast, including Pinsent Masons Belfast LLP , TLT and DAC Beachcroft , while international players such as Allen & Overy LLP , Herbert Smith Freehills LLP  and Baker Mckenzie  have chosen the city as a base for major back office support bases.
