About
Herbert Smith Freehills Kramer
Herbert Smith Freehills Kramer (HSF Kramer) is a leading international law firm and one of the UK’s most prestigious firms.
It’s a member of the Silver Circle, the group of leading UK law firms that sits just behind the Magic Circle in terms of prestige, and is regarded by many in the industry as the most prestigious firm outside of the Magic Circle.
HSF was originally formed from the merger of City stalwart Herbert Smith and Australian firm Freehills in 2012. It combined Herbert Smith's strong UK and European presence with Freehills' leading position in the Asia-Pacific region (Freehills was considered one of the ‘Big Six’ Australian law firms) in a strategic move to create a global law firm capable of competing at the highest level internationally.
The combination brought together two firms with rich legacies and complementary strengths, and was emblematic of the trend towards globalisation in the legal industry, as firms sought to better serve clients with needs across multiple jurisdictions.
In a similar vein, Silver Circle rival Ashurst merged with Australian firm, and fellow ‘Big Six’ member, Blake Dawson in 2012, while Magic Circle firm Linklaters entered into a long-term strategic alliance with Allens in the same year. In summary, 2012 was a busy year for tie-ups between UK and Australian law firms!
Herbert Smith Freehills' merger was considered a success and the firm continued to perform strongly until its next move: a merger with US firm Kramer Levin. That tie-up officially went live in June 2025, creating HSF Kramer, a global player with more than $2 billion in annual revenue, 2,700 lawyers (including around 630 partners) and 26 offices worldwide.
The merger created the first truly transatlantic and transpacific law firm, combining HSF’s deep roots in the UK, Australia, Europe and Asia with Kramer Levin’s foothold in the US.
HSF Kramer is renowned for its market-leading litigation and disputes practice. The firm is frequently the go-to choice for complex, high-value legal disputes across multiple jurisdictions. It is also known for its strengths in corporate/M&A, energy, resources and infrastructure, and real estate.

Other things to know
Advice to the Post Office: HSF played a significant role in the aftermath of the Post Office Horizon IT scandal - widely considered one of the biggest miscarriages of justice in British legal history.
The firm was engaged by the Post Office in 2019 to assist with the group litigation brought by sub-postmasters who were wrongly accused of theft and fraud due to errors caused by the defective Horizon IT system. HSF also advised the Post Office on the subsequent compensation schemes and the public Horizon IT inquiry. It was revealed that HSF had earned £163 million in fees from the Post Office up to March 2024.
Sanctions fine: In March 2025, HSF was fined £465,000 for breaching UK sanctions on Russia. The breach related to "human error" payments made to sanctioned Russian banks as the firm was shutting down its Moscow office in May 2022.
*These events both happened before the merger that created HSF Kramer in June 2025.
