A Conversation with Patrick Sarch | White & Case

In this episode, we sit down with Patrick Sarch, Partner at White & Case and Head of the firm's UK Public M&A practice, to explore his unconventional journey into law, his experience advising on some of the UK's most significant corporate transactions, and the lessons he has learned over three decades in M&A.
Patrick's route into the legal profession was anything but conventional. Leaving school at 17, he found himself working on the trading floor of a London investment bank in 1986, just as the Big Bang reforms were transforming the City's financial markets. What began as a two-week summer job became almost a year of exposure to the world of finance, where Patrick developed a fascination with the mergers and acquisitions being negotiated behind closed boardroom doors.
After studying banking and international finance, travelling and spending time pursuing his passion for music as a DJ, Patrick eventually decided that qualifying as a lawyer could provide a route into the transactions that had captured his interest. The journey was not straightforward. It took nine years from leaving school to beginning his training contract, and 86 applications to law firms resulted in just four interviews and one offer. Patrick recalls driving around London in his Fiat Panda to deliver applications by hand, partly because it was cheaper than buying 86 stamps.
His early experiences as a corporate lawyer quickly confirmed his interest in M&A. As a trainee, he worked on the hostile takeover battle between Granada and Forte, spending weekends reviewing documents as part of the due diligence process. Although the work itself was far from glamorous, the scale and intensity of the transaction left a lasting impression. It was his first real introduction to the world of public takeovers and the beginning of a career spent advising on some of the market's most complex deals.
The conversation explores how Patrick's career developed alongside major changes in the UK corporate landscape. He recalls working on the merger between Guinness and Grand Metropolitan that created Diageo in 1997, including the rather less glamorous responsibility of registering the new company's name at Companies House. With mobile phones and electronic processes still far from ubiquitous, the transaction involved a degree of logistical improvisation that would be difficult to imagine today.
Patrick also shares stories from the front line of hostile takeovers, including the extraordinary pace at which contested transactions can unfold. He recalls advising during Saint-Gobain's hostile bid for BPB, when a fax announcing the proposed takeover arrived in the middle of a board meeting, giving the company just an hour to respond. The experience illustrates the combination of urgency, strategic thinking and composure required when advising boards facing unexpected corporate challenges.
One of the most formative periods of Patrick's career came during the global financial crisis. As financial institutions faced unprecedented pressure, lawyers and advisers found themselves working around the clock on transactions that would ordinarily have been considered impossible to execute within such compressed timescales. Patrick reflects on the intensity of trying to rescue struggling businesses, raise capital and complete emergency transactions, including Barclays' acquisition of Lehman Brothers' North American business following the bank's collapse.
While the experience was professionally extraordinary, Patrick is equally candid about the personal pressures that accompanied it. With a young family and significant responsibilities outside work, he learned the importance of recognising that even the most urgent transaction must sometimes take second place to family and health. He explains why having sufficiently strong teams is essential, allowing colleagues to step away when personal circumstances demand it without feeling that everything will fall apart in their absence.
A central theme throughout the discussion is what distinguishes an exceptional M&A lawyer from someone who is simply technically proficient. Patrick explains that the greatest value lawyers bring to complex transactions often lies in their ability to exercise commercial judgement, anticipate problems and develop creative solutions. Whether helping to rescue a business, navigating competing stakeholder interests or finding a way through an apparently insurmountable obstacle, the role demands far more than an understanding of legal documentation.
Developing trusted relationships with clients is equally important. Patrick discusses the challenges of advising senior executives during difficult situations, particularly when the advice they need to hear may not be what they want to hear. Rather than simply agreeing with a client's preferred course of action, he believes lawyers build credibility by being prepared to offer an honest assessment, communicate difficult messages constructively and demonstrate that their judgement can be relied upon.
The conversation also explores leadership and the responsibility that comes with running complex transactions and managing large teams. Patrick reflects on the importance of maintaining high standards while recognising that mistakes are inevitable, particularly when junior lawyers are learning. He discusses the need for partners to take responsibility for their teams, provide clear direction and create an environment in which lawyers can develop confidence and sound professional judgement.
When it comes to recruiting and developing junior lawyers, Patrick places particular emphasis on qualities that cannot necessarily be measured through academic results alone. Resilience, ownership and judgement are among the characteristics he values most. He explains why lawyers need to be willing to take responsibility, respond constructively to setbacks and develop the confidence to make decisions rather than simply follow instructions.
Patrick also discusses the entrepreneurial side of legal practice, including the importance of recognising opportunities to develop new areas of expertise and respond to changing client demands. He reflects on building a successful public M&A practice and why lawyers who want to progress into leadership positions need to think beyond the immediate transaction, developing a broader understanding of clients, markets and the commercial opportunities facing their firms.
Looking ahead, the conversation turns to the future of the legal profession and the growing influence of artificial intelligence. Patrick acknowledges that nobody can predict precisely how AI will reshape legal careers, but sees considerable value in remaining adaptable as new specialisms and opportunities emerge. From AI-related legal work to the developing field of space law, he points to the importance of recognising that the skills lawyers will need in the future may differ considerably from those traditionally associated with their practice areas.
His advice to younger lawyers is to keep their options open. Rather than becoming too narrowly focused on a particular role or specialism, Patrick encourages lawyers to develop transferable skills, seek varied experiences and take advantage of opportunities to work across different markets, clients and jurisdictions. He believes that broadening a lawyer's capabilities not only creates greater career flexibility but ultimately makes them more valuable to the organisations they work for.
Throughout the conversation, Patrick offers a refreshingly candid perspective on the realities of a career in corporate law, from the unpredictability of his own journey into the profession to the pressures of advising on transactions that can reshape entire businesses. His experiences demonstrate that successful legal careers are rarely linear and that resilience, curiosity, commercial awareness and the willingness to embrace unexpected opportunities can be just as important as technical expertise.
It is an engaging and insightful conversation about hostile takeovers, landmark M&A transactions, leadership, client relationships and what it takes to build a successful and fulfilling career in law.
