Top-10 firm Norton Rose Fulbright has revealed it will merge with US-based international firm Chadbourne & Parke later this year.

The merger will take effect in the second quarter of 2017, Norton Rose announced.

Following the combination, the firm will continue to be known as Norton Rose Fulbright.

The global firm will comprise more than 4,000 lawyers in 58 offices spanning 32 countries – including more than 1,000 US-based lawyers.

Earlier this month the Gazette reported that the tieup would create a firm well into the top ranks by turnover. Norton Rose’s turnover last year stood at £1.1bn while Chadbourne & Parke’s was £198m.

Peter Martyr, global chief executive at Norton Rose, said: 'We are delighted to unite Norton Rose Fulbright with Chadbourne & Parke to create a global law firm that few can match.

‘We will benefit from new offices in Mexico City, São Paulo and Istanbul, and we will be able to offer our clients expanded capabilities in London, Dubai, Latin America and other key markets.’

Andrew Giaccia, Chadbourne & Parke’s managing partner, added: ‘Coming together will give us the ultimate advantage of offering superior legal service in virtually all of the world’s key business and financial centers.

‘Our firms share a strategic vision and client focus, and we have highly complementary practice and industry strengths.’
