Another global law firm combination is in the works, with New York-based Chadbourne & Parke and international giant Norton Rose Fulbright in talks for a deal that would create a nearly 4,000-lawyer firm, with roughly $2 billion in combined revenues and particular strength in global energy sector deals, project finance and disputes.

Both firms confirmed the discussions on Thursday. A vote could come soon, with consideration by some committees and the firms’ partnerships within the next few weeks, according to a partner at one of the firms who has been involved in the talks.
