Our international lawyers regularly receive honours from organisations such as Citywealth, Legal Week, Spears 500, and the legal directories Legal 500 and Chambers & Partners.

The key to our success is the fact that we do international law a bit differently.

Case Study – £12.5m International M&A Deal

We helped Mike sell his technology business, Autocoding Systems, to a large publicly-traded American corporation.

Autocoding Systems are based in Runcorn in the UK and specialise in software that automates and controls workflows for consumer product packaging lines. They already had an international presence before the deal, with clients around the world and operations in Melbourne, Australia, and Chicago, USA.

An international deal of this size involves a lot of due diligence, and Mike knew that they needed lawyers with the right level of M&A experience to complete the deal quickly. Along with his FD, John, he interviewed lawyers from a shortlist of firms which he felt were up to the job.

They chose to work with our corporate team, who successfully completed the £12.5m on time in February 2021.

"There was a really good allocation of resource by Irwin Mitchell so you didn’t feel like you were competing for their headspace. They knew that what we needed was 100% intensive support for a number of weeks or months – we were an important deal so we got a partner and we got a team and whatever we needed, we got."

Mike Hughes, Managing Director, Autocoding Systems

Testimonials & Feedback

We truly value the feedback we receive from both our clients and legal accreditation societies, such as The Legal 500 and Chambers & Partners.


“Irwin Mitchell is our ‘go to’ UK adviser. Their reputation in the French market is second to none and we have complete confidence that our clients are in safe and excellent hands.”


“I couldn’t recommend and praise them enough. They were at all times extremely professional while being personable and a pleasure to deal with. They always ensured someone (with suitable knowledge of the transaction) was available to deal with urgent issues and would give me the nudge when I was the one holding things up. The quality of the advice was outstanding and the team took all complexities (of which there were many) into account in providing it.”

Client, complex cross-border transaction involving multiple jurisdictions and sellers

“The team was excellent in managing advisers across multiple jurisdictions to find a solution that worked cross-border and not just simply in the UK. Beyond technical ability, they showed impressive cultural intelligence and their bilingual language capabilities are a real asset.”
