Tatham & Co and Sea Green Law announce maritime law merger

Tatham & Co and Sea Green Law, two leading specialist maritime law firms in the UK, are merging to create a 22 lawyer practice, and a stronger version of themselves.

The combined entity began operating on 1 April 2025 under the Tatham & Co name, will be jointly led by lead Partners Stephen Askins and James Hickland from Tatham & Co, and Ted Graham from Sea Green Law.

By combining their expertise and resources and building on the success of the two firms, the expanded Tatham & Co will have the capacity and capabilities to handle a greater number of larger cases on the contentious side, alongside providing a wider range of expertise to their client base. It will enhance the firm’s dry shipping and sale of goods capability, whilst complimenting Tatham & Co’s existing admiralty team. Partners from both firms know each other well, having worked together for many years previously, share similar values, visions and culture and are well adapted to continue to serve the maritime law sector.

“For the past six years, Sea Green Law has grown steadily and we have been very successful, whilst maintaining work life balance. But the young lawyers want to work in London and we are excited about being back in the heart of one of maritime’s most important cities,” said Ted Graham.

“We are delighted that Sea Green have agreed that the time is now right for us to join forces and take our combined maritime law expertise to the next stage. Ted and his entire team are incredibly well respected in the market. The merger creates synergies and efficiencies which will benefit both clients and the firm itself. Having them on board gives us more depth and resilience in an increasingly competitive sector,” said Stephen Askins.
