The Emergence of Legal MSO's

​

Shelton & Steele began advising law firms on MSOs in 2024, the same year Frederick Shelton was quoted in The American Lawyer about the emergence of this model. We act as trusted advisors, helping law firms evaluate and select the right MSO partnership for their goals.

​

What Is a Legal MSO

A Legal Management Services Organization (MSO) is a Rule 5.4-compliant business platform. In it's standard form, it supplies operational support, including HR, accounting, marketing, and IT. Many MSOs implement AI tools and help firms modernize their operations.

The law firm remains one hundred percent attorney-owned and professionally autonomous. The MSO provides business services through a Management Services Agreement. It does not take equity in the law firm or share legal fees.

​​

1. Standard Legal MSO

The Standard MSO is a privately managed business platform that supports multiple independent law firms. Each firm retains its own name, culture, and leadership. The MSO centralizes operations and provides business support through an MSA. It does not acquire ownership or influence legal judgment. The Standard MSO builds a national network of independent law firms supported by the MSO. This provides "enterprise level pricing" and access to the most elite software, AI, C-level and support personnel, and other products and services needed by law firms. 

The Standard MSO is ideal for partners who want relief from administrative burdens so they can focus on client development, lawyering and growing their firm. 
 

2. Private Equity Backed Legal MSO

The Legal MSO's that Shelton & Steele partners with are not private equity funded. Our experience and feedback from partners at firms where PE firms acquired the back office functions was that in their endeavor to quickly sell what they bought, PE firms were disruptive to firm culture, fired long-time employees and replaced them with less qualified or outsourced personnel, and created more problems than they solved. While they do promise the capital to scale, growth just for the sake of growth - or to position a firm's back-office functions for quick sale, does not seem to be in the best interest of the firm. 
The only fund-backed MSO's that Shelton & Steele will work with, are financed by LTIF's (see below).

​

3. Corporate / Litigation Finance Backed Legal MSO

Simply put, these MSO's offer nominal capital, limited utility and back office support, but definite access to litigation funding for cases that are larger than a small to medium-sized firm would normally be able to handle. 

These are typically formed by litigation funding companies or legal service platforms offering firms access to tech, infrastructure, and financing—especially for large litigation portfolios.

While these can be useful in narrow verticals (like PI or mass torts), they typically offer minimal upfront capital and are not true partnership models. They're best for litigation-heavy practices looking to finance large cases, and firms with limited need for operating capital or transformation

We do not recommend these for firms seeking meaningful M&A-level capital or long-term strategic alignment.

​

The Long-Term Investment Fund (LTIF) Backed Legal MSO

These are MSO's that are backed by investment funds, with 15 - 20 year buildout objectives. These funds preserve firm culture and leave every single current employee in place (unless the partners indicate they want to make changes). Like the Standard MSO, these funds build a national network of independent law firms supported by the MSO. This provides "enterprise level pricing" and access to the most elite software, AI, C-level and support personnel, and other products and services needed by law firms. 

The fund provides upfront capital to equity partners for the value they've built, as well as significant infusions of capital to assist with recruiting and financing the salaries of new attorneys and groups. They also finance  upgrades in technology and cover and manage all administrative operations.
Finally, they offer structured retirement payouts and continuity planning. Each firm remains attorney-owned and operates under a Management Services Agreement that protects their autonomy and independence. 
They do all this on a flat fee or similar basis which has been proven Rule 5.4. compliant for over 4 years now. 

This model best suits firms with three to fifty million dollars in annual revenue. It works best for partners who want liquidity, growth capital, and legacy planning.
