Norton Rose Fulbright will temporarily retain its legacy Fulbright & Jaworski name in the US for regulatory reasons, it has emerged, as the firm seeks the approval of local state bars to formally change its legal identity to reflect the transatlantic merger.

The newly merged firm, which was formed last week under the global brand of Norton Rose Fulbright, is still legally registered as Fulbright & Jaworski in the US.

The firm explained that as legacy Fulbright practises in 50 states across the US, it now faces a complex and potentially lengthy process to comply with local bar rules on name changes. It confirmed that it plans to change its US legal entity name as soon as it is able to do so.

Separately, it emerged earlier this week that Norton Rose Fulbright is expected to see the post-merger departure of several lawyers in Dubai, with a team from legacy Fulbright understood to be on the verge of a move.

The bulk of Fulbright's eight-partner operation is reportedly considering a move to another firm in the emirate, with US firm Baker Botts understood to be in talks to take on a team.

Norton Rose and Fulbright's legacy Dubai practices are based in two separate offices in the emirate, operating with different profit pools. The UK partnership is based in the Dubai International Financial Centre (DIFC), while the US partnership is working from Festival Tower. 

Last month the firm cited difficulties in obtaining an offshore licence to practise in the DIFC as the main reason for maintaining distinct offices.
