Combinations in the legal and intellectual property (IP) sectors have been on the rise in recent years, driven by factors such as increased globalisation, client demands for broader services, and the pursuit of economies of scale. While the motivations for combinations are often clear, enhancing capabilities, expanding geographic reach, or securing financial stability, the reality of executing a successful combination is anything but straightforward.

No matter the structure, merger, acquisition, asset purchase agreement, or succession buyout, for every deal that reaches completion, there are countless others that falter before the finish line. Many times, success – or failure – boils down to what can be called the eight ‘Cs’ of combinations.

Top Eight ‘Cs’ of Combinations

Law firm leaders, whether consciously or not, are acutely aware of these key considerations, which must be carefully managed to ensure a smooth and successful merger.

  1. Culture: A firm’s culture, including but not limited to, its approach to work, how it rewards / encourages collaboration, client service philosophy, and values, is often cited as the most significant challenge in law firm mergers. Even the most financially compelling transactions can unravel if cultural misalignment leads to internal discord or client attrition. Leaders must carefully assess cultural compatibility and proactively plan for integration.
  2. Conflicts: Client conflicts of interest present a unique challenge in law and IP firm combinations. Regulatory and ethical considerations mean that firms must conduct thorough conflict checks early in the process to avoid jeopardising client relationships or violating professional standards. Failure to address conflicts can lead to deal breakdowns or operational challenges post-merger.
  3. Compensation: The alignment of partner compensation structures is one of the most critical and sensitive aspects of any transaction. Disparities in profit-sharing models, bonus structures, and equity distribution can create friction among partners, leading to dissatisfaction and even departures. Addressing these differences early in negotiations is crucial to avoiding post-merger discontent.
  4. Control: Decision-making authority and governance structures can become contentious issues during merger discussions. Who will lead the combined firm? How will voting rights be distributed? What role will legacy firm leadership play post-merger? What will the combined firm be called? These questions must be addressed early to prevent power struggles and ensure long-term stability.
  5. Clients: Even if ethical conflicts do not threaten the potential loss of a client, the change associated with any significant combination can pose a risk. As such considering client retention is a top priority during any deal. Firms should consider business conflicts, potential changes to rates, panel counsel processes, and relationship partner succession as part a combination. And when the time is right, firms must reassure key clients that the merger will enhance, rather than disrupt, their service experience. Clear communication and proactive client engagement can help maintain trust and loyalty throughout the transition.
  6. Continuity: Business continuity during and after the merger is vital for maintaining productivity and client service levels. Effective transition planning, including technology integration, operational streamlining, and clear internal communication, can minimise disruptions and ensure a seamless transition. This integration plan should be fully understood, appropriately mapped, and adequately staffed. This planning will not only help you identify key considerations and costs associated with the deal, it will ensure your combination results in optimal ROI.
  7. Capabilities: The strategic rationale for a merger often hinges on the enhancement of practice capabilities and geographic reach. Firms must ensure that their combined expertise creates a competitive advantage while addressing any gaps in service offerings or operational efficiencies. Looking at ways deals can be additive and appropriately being able to demonstrate this to the decision makers (e.g., a firm’s equity partnership) can be vital in obtaining a positive election result.
  8. Costs: Transactions of any kind involve significant costs, from legal fees to technology integration and real estate to rebranding. Proper budgeting for these expenses is essential to prevent financial strain and ensure long-term profitability. These elements should be considered at the start and be part of any deal’s financial analysis.

Learning from Leaders – Thomas Gaunt

To provide further insight into the challenges and strategies involved in law and IP firm combinations, we spoke with Thomas Gaunt, Partner & Head of Intellectual Property at Lewis Silkin who has firsthand experience navigating successful combinations. Below are four key questions we asked him to help shed light on the realities of law firm combinations:

How did you assess cultural compatibility between the firms, and what strategies did you use to integrate different workplace cultures?

There’s no substitute for spending time together. Throughout the discussions and negotiations, it’s good to make time for a number of more social ‘chemistry’ meet-ups – this is a chance to gauge whether you get on and think about business and workplace values in a similar way. Arranging these in different settings and mixes of people is another useful tool in finding common ground and building understanding and trust. The negotiations themselves will also tell you a lot about culture; they start to highlight how firms look after their employees and what’s really important to them.

Once the merger has happened, focus then needs to turn to integrating the teams – it’s easy to forget that the partners will have had several months to get to know each other, but typically staff don’t find out until immediately beforehand. Planning social events and in-office time is important, especially given the prevalence of remote working. A buddy system can help new team members adjust to new ways of working, and partners need to make time to facilitate integration.

What lessons did you learn from successful deals, and what would you do differently in hindsight?

I think it’s a good idea to try to work out what the deal-breakers might be relatively early on and brainstorm possible solutions to these. It’s a difficult balance because you’re still building rapport at this stage, and so you may not be willing to admit what creative solutions you’d be prepared to accept yet to get the deal over the line. However, some problems are genuinely insurmountable, and so it’s better to reach that conclusion quickly and move on if you have to.

For me, one of the most important lessons is to make sure both parties’ interests are aligned. It may be initially attractive to devise a complicated commission-type arrangement in the interests of making the deal fair based on current remuneration levels, but careful thought needs to be given to the longer-term effects of this. For instance, if the objective is to build the strongest combined team possible, any arrangement which favours work being directed solely to particular people will be a barrier to that integration in the long run.

How do you ensure that key clients remain confident and engaged during the combination process?

It’s important not to rush things. Clients will be concerned about service levels dropping and charges increasing, so the immediate message needs to be that these are staying exactly the same – but with the added benefit of a bigger platform. As part of this, I wouldn’t rush to merge processes too early; let clients get used to the new letterhead before you make any noticeable changes in the way you do things. Of course, if you can roll out an immediate (free) value-add, such as some new analytics or thought leadership from a new colleague, that can certainly be helpful.

What role did external advisers play in your combination, and how did their involvement impact the outcome?

Making a successful deal without engaging an experienced broker like Adamsons would be very difficult. They know the market and are able to quickly identify prospective firms with a similar culture and values. Adamsons also played an important role in getting the deal over the line; negotiations can be tough, and so having a third party involved who has experience of these deals can help to manage expectations and build trust between each side. For example, it provides a sounding board and route to sensitively address concerns and blockers, as well as helping to mediate ways through these during the negotiation process.

Conclusion

Law and IP firm combinations are complex undertakings with historically high failure rates, often cited between 70% and 90%. While many firms attempt to navigate discussions internally, the reality is that conflicting priorities, time constraints, and the intricacies of negotiation frequently derail these efforts. Engaging professional consultants can significantly influence the success of a deal, providing strategic guidance, objective mediation, and structured planning to avoid common pitfalls. By incorporating real-world insights from experienced leaders and applying a structured, strategic approach, firms can navigate the complexities with confidence. The key is not just understanding these complexities, but managing them effectively.
