The Management Services Organization (MSO) model has become a familiar tool for investors entering regulated industries. It is best known in healthcare, where strict ownership laws prevent non-physicians from owning medical practices. The MSO structure offers a legal pathway for investment and has helped scale telehealth providers, behavioral health groups, dental practices, and clinics of all kinds.
As private equity looks for new opportunities, law firms have begun asking a clear question:
Can law firms use the MSO model to raise outside capital or partner with private equity?
The short answer is yes, but only in specific situations. The longer answer is that the MSO model works very differently in legal services than in healthcare, and many firms will not benefit from it in the same way.
This guide explains why MSOs exist, how the structure applies to law firms, and when it may offer real value. It also outlines how LumaLex Law helps firms design compliant MSO structures with the goal of withstanding regulatory scrutiny and supporting long-term growth.
1. Why the MSO Model Exists in Healthcare
MSOs are common in healthcare because the industry faces strict Corporate Practice of Medicine (CPOM) laws. Many states bar non-physicians from owning medical practices or influencing medical decisions. Investors work around this through a split structure:
- A physician-owned professional corporation (PC) delivers clinical care.
- A non-physician-owned MSO owns the non-clinical assets and provides management services.
- The MSO earns a management fee for staffing, billing, marketing, technology, and operations.
This structure is attractive because:
- CPOM prohibits non-physician ownership.
- Clinics need capital for expansion, staff, technology, real estate, and infrastructure.
- The distinction between “clinical” and “non-clinical” tasks is clear.
- Investors can scale multiple clinics and centralize operations.
- Transaction multiples in healthcare are often high.
Because of this mix of regulatory pressure and business demand, MSOs have become the dominant investment vehicle across medical and dental practices, behavioral health centers, and veterinary practices.
LumaLex Law has deep experience building MSO structures in these sectors. The firm regularly advises telehealth platforms, ketamine clinics, behavioral health programs, and other regulated operators.
2. Applying the MSO Structure to Law Firms
Law firms are also restricted by ownership rules. Most states prohibit non-lawyers from owning law firms, sharing legal fees, or influencing legal judgment. These rules serve the same purpose as CPOM: protecting professional independence.
Because of this, law firms can in theory use the MSO structure:
The Law-Firm MSO Structure
A law-firm MSO structure looks like this:
- A law firm organized as a PC or PLLC is fully owned by licensed attorneys.
- A non-lawyer-owned MSO handles:
- Marketing
- Staffing
- Office administration
- Technology systems
- Intake and call centers
- Billing and finance operations (non-legal)
- Real estate and equipment
- The MSO charges the law firm a management fee in exchange for these services.
This structure allows:
- Private equity to invest in the MSO rather than the law practice.
- Firms to raise capital for business functions without giving up ownership of legal services.
- Sale or partial sale of the MSO to monetize non-legal assets.
For firms with substantial technology, strong branding, or a national footprint, an MSO may create real enterprise value.
But the model does not translate perfectly, and the differences matter.
3. Why the MSO Model Is Harder to Use in Legal Services
A. No Clear Divide Between “Legal” and “Non-Legal” Work
Medicine has a strict line: only clinicians can diagnose, prescribe, or treat. Everything else is non-clinical.
Legal practice is not structured in the same way. Most of the value that clients pay for comes directly from attorney work. Intake, case management, and support functions help, but they do not define the core service. Because of this, fewer business functions can shift to an MSO without risk of unauthorized practice of law.
B. Law Firm Revenue Depends on Attorney Time
Legal services scale through professional labor, not volume. In healthcare, clinics can scale patients through systems and staff. Law firms rely on:
- Attorney expertise
- Attorney time
- Direct supervision
- Professional advocacy
This limits the high-margin, high-growth upside that private equity investors often seek.
C. Ethics Rules Are Stricter Than CPOM
State Bar rules restrict:
- Fee-sharing with non-lawyers
- Ownership by non-lawyers
- Control over legal judgments
- Client confidentiality
- Conflicts of interest
Healthcare regulators allow MSO structures with clear boundaries. Bar regulators face a broader range of possible violations and often apply a more conservative approach.
D. Investors Have Fewer Operational Levers
In healthcare, investors can:
- Improve payer contracts
- Optimize billing
- Consolidate clinics
- Automate systems
- Acquire numerous sites
Law firms do not offer the same operational levers without crossing ethical lines.
E. MSO Valuations Are Lower in Legal Services
Because so much value remains tied to attorney labor, law-firm MSOs often sell at:
- 3 to 7 times earnings
while healthcare MSOs may sell at:
- 10 to 18 times EBITDA
This difference affects investor interest and reduces the incentive for many firms.
4. When the MSO Model Does Work for Law Firms
Despite these limitations, the MSO model can create real value when used in specific situations. The key is whether the firm has significant non-legal assets that an investor can help grow.
A. Tech-Enabled Law Firms
Firms with strong operational systems may have assets that fit well within an MSO:
- AI-supported workflows
- Automated document platforms
- Custom intake or CRM systems
- Subscription-based legal products
- Client portals
- Content libraries
- Online education products
These assets can be owned by the MSO and can generate recurring revenue.
B. Multi-State or National Firms
National or multi-jurisdictional firms rely heavily on:
- Centralized marketing
- Intake systems
- Technology
- Scalable operations
These can be placed in an MSO to support large-scale growth.
C. Hybrid Legal and Non-Legal Businesses
The MSO model works well when a law firm owns or launches adjacent businesses, such as:
- Document automation tools
- Case-management software
- Compliance systems
- Consumer-facing legal tech
- Legal subscription platforms
The more non-legal assets a business has, the easier it is to justify MSO investment.
D. Firms Planning for Private Equity in the Future
Private equity increasingly invests in legal-adjacent companies, including:
- Mass-tort intake platforms
- Personal-injury marketing and lead-generation companies
- Bankruptcy processing companies
- Immigration tech tools
A firm with strong systems and a well-structured MSO may position itself for a future acquisition.

Proceed with Care
The MSO model transformed healthcare by giving investors a compliant way to support growth and scale. It can also create new opportunities for law firms, but only when used with care. The legal industry does not mirror healthcare, and the MSO model should never be copied without understanding the differences.
For tech-enabled, system-driven, multi-state law firms, the MSO model can provide a path to raise capital, expand, or monetize non-legal assets. For more traditional firms, the model may offer limited value.
