Chadbourne & Parke's London, Dubai and Moscow offices will join Norton Rose Fulbright's Europe, Middle East and Africa (EMEA) partnership when the tie-up between the two firms goes live in the second quarter of this year.

The offices and their partners will financially integrate with the UK-headquartered firm's EMEA LLP from day one of the $2bn (£1.61bn) union between the two firms, which was confirmed yesterday (21 February) after months of discussions.

According to Chadbourne's website, the firm has eight partners and nine "international partners" in London, two partners and three international partners in Dubai, and two partners and two international partners in Moscow.

International partner is a non-equity role.

The union gifts Norton Rose three new international bases – a long-sought office in Mexico City, one in Istanbul and another in Sao Paulo. Chadbourne also has an office in Johannesburg, which will join Norton Rose Fulbright's African verein. The Mexico and Istanbul offices will be part of the US arm of the business, which is led by managing partner Daryl Lansdale (pictured above left).

"The intention was always to assimilate those international offices into the pre-existing Norton Rose operations from day one," said Norton Rose Fulbright global CEO Peter Martyr (pictured above centre).

While the key focus of the deal is to grow in New York and Washington, Martyr said there will be "further opportunities" for growth in London.

Chadbourne managing partner Andrew Giaccia (pictured above right) said there were currently no plans for "cost reductions and redundancies". He added: "They are not a priority at this time. The combination is being done to expand and grow out our business. We are putting the firms together and we're not in each other's way. We can really anticipate everything moving into Norton Rose."

The merged firm will operate as Norton Rose Fulbright. Chadbourne, which was an independent firm for 115 years but had struggled to retain partners in recent months, will lose its name as a result of the union.

The combination creates a firm with around 1,000 lawyers in the US, including more than 300 in New York and around 130 in Washington DC. Globally, it will house more than 4,000 lawyers across 58 offices in 32 countries.

News of the merger talks broke earlier this month (2 February) after months of discussions.
