Dentons' tie-up with Australia's Gadens will formally complete next week (5 December), more than a year after partners first approved the deal.

Gadens operates a federalised model across Australia, with its offices in Brisbane, Melbourne and Adelaide set up as separate entities from those in Sydney, Perth and Port Moresby, which are integrated.

The integrated offices will join Dentons, while those in Brisbane and Adelaide will become associate firms of Dentons Australia.

In October, it emerged that Gadens' Melbourne office would break away from the merger. The firm closed its Singapore office in May this year, when office managing partner Marc Rathbone joined Nabarro.

Dentons' global chief executive Elliot Portnoy said: "Our clients, particularly those in China, Singapore, Hong Kong and South Korea, responded enthusiastically to the announcement of our combination.

"Adding market-leading experience in Australia's banking and finance, real estate, infrastructure, energy and natural resources sectors to our global teams significantly enhances our offerings to clients in the Pacific Rim."

Last month, Dentons announced it is set to move into the Central American market through a tie-up with Costa Rica-based firm Munoz Global, a deal that will also see the international firm gain bases in Panama and Nicaragua.

The combination is subject to a vote by partners at both firms.

Dentons is also understood to currently be in discussions to take on King & Wood Mallesons'  beleaguered European and Middle East arm.
