Simcocks has become the first Isle of Man (IoM) law firm to launch a London office.
The 20 fee-earner firm is seconding five lawyers initially to staff the new office, which will provide Manx law advice.
Simcocks' chief executive officer (CEO) Phil Games said: "Seventy per cent of our work comes from London, so it makes sense to have people on the ground. We also want to use the London office to make people aware of our IoM services."
Initially, Simcocks plans to second lawyers to London. Unusually, the firm recently replaced a traditional partnership structure for what it views as a more efficient company arrangement in which directors have superceded partners and a CEO has replaced the post of senior partner.
The Manx parliament recently rejected Simcocks' proposal to allow IoM firms to enter multinational and multidisciplinary partnerships.
Alongside its core legal practice, it also owns Simcocks Pensions, providing advice to conglomerates wanting to set up funds on the island.
