Why Law Firms Should Avoid the Overwhelming Majority of MSOs

"We have declined to work with more than ninety percent of the legal MSOs because we concluded they would do law firms more harm than good."

The Legal MSO market is expanding at an extraordinary pace. Nearly every month another platform enters the market promising capital, technology, recruiting, AI, acquisitions and exponential growth. To the average law firm, many of these organizations appear remarkably similar. Their presentations use the same buzzwords, the same projections and, increasingly, the same promises. That is precisely why law firms should approach the market with a healthy degree of skepticism.

Over the past two years, Shelton & Steele has evaluated more than seventy Legal MSOs on behalf of law firms. We are not investment bankers attempting to close transactions, nor are we private equity sponsors looking to deploy capital. Our role is to evaluate these organizations from the law firm's perspective and determine which ones are genuinely capable of creating long term value. After completing that analysis, we reached a conclusion that surprised even us.

We actively work with only six Legal MSOs.

One is a standard MSO that takes no equity at all. They simply take over all back office functions and save the firm money and a ton of time.

Two serve the personal injury market and one of those is not private equity backed. They’re corporate backed so there’s no pressure to scale rapidly and crush autonomy and culture in the process. They have not chosen to announce their entry into the market yet so most law firms doing deals now, will never know about them until they've done a deal with someone else.

Three focus primarily on corporate and business law firms. All three have heavy legal backgrounds and longer timelines the usual private equity with their Scale to Sale model.

That means we have declined to work with more than ninety percent of the legal MSOs we have evaluated because we concluded they would do law firms more harm than good.

The reasons for rejection are surprisingly varied, and occasionally entertaining.

We've had slick talking "PE Bros" literally ask us how they could get around Rule 5.4 and Unauthorized Practice of Law restrictions. These PEs are going to be the Avianca Airlines Moment (the infamous AI generated brief that cited fake cases) of legal MSOs. They’ll lose their investor’s money and cost lawyers their licenses. But they won’t stop the inevitability of Legal MSOs because when they’re done right, they’re just too good to ignore.

We've reviewed deal structures that looked perfectly acceptable until you realized they effectively turned law firm partners into indentured servants who could never leave unless it was “mutually agreed upon” by the PE – oh and that most of the firm's staff would eventually be shown the door in the name of "operational efficiency."

We've seen structures where, if the firm had a great year, the private equity sponsor captured most of the upside, yet if the firm had a disappointing year, the lawyers were expected to absorb most of the downside. Not exactly Win / Win.

We've even reviewed pitch decks confidently projecting that private equity would increase a law firm's profitability by fifteen times in less than three years. We suggested they start researching rehab centers immediately.

There are reasons we have evaluated more than seventy Legal MSOs and chosen to work with only six. It's because we ask all the tough questions that the typical attorney doesn't know to ask.

Those questions separate exceptional Legal MSOs from average ones, yet they are rarely the focus of initial conversations between lawyers and MSOs. Instead, many attorneys become preoccupied with valuation multiples and upfront cash. Those issues are certainly important, but they should be viewed as a benefit of selecting the right partner, rather than the criteria used to choose one.

Every Legal MSO has strengths, and every Legal MSO has weaknesses. The right partner for one law firm may be completely wrong for another. A fast growing litigation firm has very different needs than a mature corporate practice focused on succession planning. So there are two goals: The first is to avoid bad MSOs. The second, is to find an MSO whose offering of zero equity dilution, infusion of capital for growth, cultural alignment and long term vision fit your firm's goals.

Perhaps the most valuable advice we provide our clients is not which Legal MSO deserves serious consideration. It is which ones should be eliminated before valuable time is wasted and potential negative outcomes occur.

Inviting a dozen MSOs to meet and pitch may sound prudent, but sophisticated due diligence is not about expanding the list of potential partners. It is about narrowing the field because sometimes the most persuasive salespeople are the last people you want to do business with.

That philosophy explains why we work with only six Legal MSOs despite evaluating more than seventy. We are not in the business of finding law firms for every Legal MSO. We are in the business of  1. Preparing law firms in advance, so they know what to ask and watch for.

2. Protecting law firms from bad deals and

3. Providing the best counsel, as well as our network of the best MSO attorneys and consultants in the country.
