Irwin Mitchell

Spear’s Review

Full-service law firm Irwin Mitchell was founded in Sheffield in 1912. Initially a specialist in criminal law and subsequently known for its work on high-profile personal injury cases, the firm has grown through a series of mergers and acquisitions and now operates private client and business legal departments in major cities around the UK.

Lawyers aim to serve as clients’ problem-solvers, as well as their long-term strategic advisers. To this end, the firm acts for private clients across, among other areas, tax; wills, trusts and estates; family; employment; immigration; criminal; and property law. For businesses, the firm offers legal services in commercial litigation, employment, real estate, and regulatory and compliance, to name but a few.

As the UK partner of First Law International, a global network of law firms, Irwin Mitchell also can help clients access quality legal advice around the world.
