Succession Planning for Law Firms: Why More Managing Partners Are Exploring the MSO Model

Key Takeaways

• Succession planning has become more urgent for many firms as partner retirement, client transition, and leadership continuity get harder to solve through informal internal planning alone.
• More managing partners are exploring the MSO model because it can offer a practical way to strengthen the business side of the firm while supporting long-term continuity.
• An MSO can help firms think more intentionally about infrastructure, modernization, and operational support during a period of leadership transition.
• Any firm considering an MSO should evaluate the structure carefully with the right advisors and a clear understanding of what it wants to preserve.

For many managing partners, succession planning is no longer something to revisit later. It has become a current leadership issue.

A growing number of firms are facing some version of the same challenge. Senior partners are getting closer to retirement. Client relationships may still be concentrated among a small group of leaders. The next generation may be strong professionally, but not necessarily positioned to assume ownership or management in the same way previous generations did.

That is one reason more firms are taking a fresh look at the MSO model.

For law firm leadership, the interest is often practical rather than theoretical. The question is whether an MSO-supported structure could help create more continuity, stronger operational support, and a more durable platform for the future of the firm.

Why Succession Planning Feels More Pressing

Many firms still rely heavily on a small number of senior partners for revenue, client retention, leadership, and strategic direction. That concentration can work for a long time, until it starts to create pressure around retirement timing, continuity, or the long-term future of the platform.

At that point, succession becomes more than a partner-level issue. It becomes a broader strategic question about how the firm will continue to operate, grow, and stay stable over time.

For many managing partners, the challenge is not recognizing the issue. It is finding a path that feels realistic. Some firms have younger lawyers with strong legal ability but no clear ownership transition plan. Others have talented future leaders but limited infrastructure on the business side. Some are also trying to modernize operations while maintaining continuity and preserving what makes the firm successful.

That is why succession planning is increasingly leading to larger structural conversations.

Why Traditional Internal Succession Has Become More Difficult

For years, many firms assumed succession would happen naturally. Senior partners would gradually transition clients, younger partners would step into larger roles, and ownership would evolve over time with relatively little structural disruption.

For many firms, that path feels harder to rely on today.

Younger partners may be less interested in stepping into a traditional ownership model with the same level of financial commitment or operational burden. Client relationships may still be too concentrated with a few senior lawyers. The business side of the firm may also require more sophistication, investment, and management support than it did in earlier years.

In other words, succession is no longer just about replacing people. It is about whether the firm’s overall model is built for the next chapter.

Why More Managing Partners Are Looking at the MSO Model

This is where the MSO conversation often becomes more relevant.

At a high level, an MSO structure can allow a law firm to strengthen and professionalize non-legal functions such as finance, technology, recruiting, marketing, HR, and operational support while the firm continues to focus on legal services and client work.

That can be attractive in a succession context because continuity is not only about who takes over client relationships. It is also about whether the firm has the operational foundation, reporting, infrastructure, and support needed to remain strong over time.

For many managing partners, that is where the MSO model starts to stand out. It can offer a way to think about the next phase of the firm in a more structured and forward-looking way.

How an MSO Can Support Continuity

An MSO does not replace succession planning, and it does not remove the need for leadership development or client transition. But it can support continuity by helping create a stronger business platform around the firm.

For some firms, that may mean more organized back-office operations. For others, it may mean improved technology, stronger reporting, better recruiting support, more scalable systems, or a more consistent operational structure. These are the kinds of capabilities that can become increasingly important when a firm is moving from one generation of leadership to the next.

That is part of what makes the MSO model attractive. It may help firms build a more durable operating foundation at a time when continuity depends on more than just replacing retiring partners.

Why the MSO Model Can Feel More Flexible

One reason managing partners are exploring MSOs is that the structure can open up a wider strategic conversation about the future of the firm.

Some firms want continuity without jumping immediately to a merger. Some want stronger infrastructure without overburdening the next generation. Some want to preserve culture and identity while also creating a more modern and better-supported operating environment.

An MSO can become appealing in that context because it may offer more flexibility than a purely internal transition path. It can give firm leadership another way to think about continuity, support, and long-term planning without forcing the conversation into only one traditional model.

For many firms, that flexibility is part of the appeal.

Why This Matters to Managing Partners

Managing partners are often the ones carrying the weight of both the immediate business and the longer-term continuity question. They are not just thinking about retirement timing. They are thinking about client relationships, recruiting, firm operations, governance, and whether the platform is truly built to last beyond the current leadership team.

That is why the MSO model is getting more attention.

It gives managing partners a way to think not only about succession in the narrow sense, but about what kind of platform the firm needs for its next chapter. In that way, the conversation is often bigger than succession alone. It is about whether the current structure is strong enough to support the firm’s future goals.

Signs It May Be Time to Explore Strategic Options

Not every firm facing retirements needs to pursue an MSO structure. But some firms may find that succession pressure is revealing a larger need for strategic change.

That may be the case when a small number of partners still control most major relationships, when leadership continuity feels uncertain, when the next generation is not eager to assume the traditional model, or when the firm needs stronger infrastructure than the current structure can easily support.

These kinds of signals do not automatically point to one answer. But they can indicate that the firm would benefit from evaluating whether its existing model is still the right fit for the years ahead.

What Managing Partners Should Evaluate

Before moving forward, firm leadership should stay focused on a few core questions.

What is the actual succession challenge the firm is trying to solve? What parts of the current model feel strained? What does the firm want to preserve as it evolves? Would an MSO help create stronger continuity, infrastructure, and support, or is the issue really something else?

These questions help keep the discussion grounded. They also help ensure the conversation stays strategic rather than reactive.

The most productive evaluations usually begin when leadership is clear about its objectives, realistic about the firm’s current pressures, and open to considering whether a more modern structure could support the next chapter more effectively.

Final Thoughts

For many law firms, succession planning is no longer a standalone issue. It is increasingly connected to broader questions around continuity, infrastructure, growth, and governance.

As those pressures converge, more managing partners are exploring the MSO model as a structure that may help address those challenges in a more coordinated way.

For the right firm, an MSO can provide a meaningful path forward, one that supports continuity, strengthens the business side of the firm, and gives leadership more room to think strategically about what comes next.

FAQ

Why is succession planning getting harder for law firms?

Because succession often involves more than replacing a retiring partner. It may also require client transition, leadership development, stronger infrastructure, and a clear plan for long-term continuity.

How does an MSO relate to succession planning?

An MSO can become relevant when a firm wants to strengthen the business side of the platform and create more continuity as leadership transitions over time.

Does an MSO mean the law firm is being sold?

Not necessarily. An MSO is a separate structure and should not automatically be viewed as the same thing as selling the law firm itself. The right way to understand it is in the context of the firm’s goals, governance, and long-term strategy.
