research notes compiled august 2025 for informational and educational purposes only. caveat lector.
overview
even in 2022, before ai, the legal profession was already experiencing significant structural transformation. maybe because of secular demographic trends, maybe because of the “global financial crisis,” or maybe because of prior liberalization in litigation finance and marketing - we’ll never know.
the point is, traditional restrictions on non-lawyer ownership - codified in model rule 5.41 and related concepts like champerty - are increasingly being challenged through innovative business structures and targeted regulatory liberalization.
three distinct approaches have emerged:
Three distinct approaches to structuring legal services: traditional partnerships, MSO structures, and alternative business structures
fundamental approaches
traditional law firm ownership
the baseline: lawyer-only ownership with partnership structures governed by professional conduct rules.
- traditional ownership models - partnership structures, model rule 5.4, historical context, and current restrictions
management service organizations
the workaround: splitting firms into lawyer-owned practice entities and non-lawyer-owned management companies.
- mso framework - core concepts, two-entity structures, and operational requirements
- texas ethics opinion 706 - detailed analysis of first state guidance on mso structures for law firms (february 2025)2
alternative business structures
the direct approach: eliminating restrictions entirely through regulatory reform.
- abs overview - direct ownership models, regulatory frameworks, and business model analysis
- arizona abs program - detailed case study of the most comprehensive abs program (136+ entities as of april 2025)3
international frameworks
- global approaches - uk legal services act 20074, eu halmer case implications5, and comparative analysis
advanced structure mechanisms
sophisticated financial engineering techniques enabling non-professional investment while preserving professional independence through innovative capital arrangements.
financial engineering approaches
- financial engineering - debt-to-equity conversions, revenue participation rights, contingent value rights, and convertible preferred structures
- governance and control mechanisms - management rights without ownership, call/put options, synthetic equity arrangements, and economic interests
strategic optimization frameworks
- regulatory arbitrage - cross-jurisdictional optimization, cross-border structures, IP licensing models, and international framework exploitation
- collaborative and hybrid models - joint ventures, litigation finance hybrids, management carve-outs, and strategic partnerships
complex transaction structures
- complex transaction structures - partnership interest purchases with earn-outs, sophisticated deal mechanics, and performance-based acquisitions
- advanced case studies - comprehensive analysis of Burford Capital/PCB, KMPG Arizona ABS, healthcare MSO precedents, and implementation lessons

cross-sector comparison: accounting leads legal
professional services pe investment shows stark contrast between accounting and legal sectors:
accounting sector (far ahead):
- 83 pe deals projected for 2025 vs 22 in 2024—representing 70% of all activity since 202038
- over $10 billion invested since 2020, creating ~$30b in post-deal valuations
- over half of top 30 us accounting firms expected to have pe ownership by end of 2025
- deal velocity: “one deal per day” through november 2025
- major exits: citrin cooperman pe-to-pe sale ($2b) confirms viable exit pathway
- baker tilly + moss adams merger: $7b valuation (june 2025)
legal sector (emerging):
- mcdermott will & schulte: first am law 50 firm exploring pe via mso (november 2025)
- personal injury firms: multiple firms pursuing pe through mso structures
- abs programs: 136+ entities in arizona, but mostly smaller operations
- regulatory barriers: most states maintain rule 5.4 prohibitions
key regulatory difference: accounting firms require only majority cpa ownership in most states vs law firms’ 100% lawyer ownership requirement, enabling faster pe penetration despite professional restrictions
market dynamics:
- both sectors: fragmented markets (40,000 accounting firms, thousands of small law firms)
- both sectors: technology investment pressures exceeding partnership capital
- accounting advantage: established pe-to-pe exit pathways demonstrate liquidity
- legal challenge: regulatory uncertainty limiting institutional capital deployment
[source: cpa trendlines, bloomberg tax, sidley austin]38
key tensions and considerations
the regulatory landscape reflects fundamental tensions:
access to justice vs professional independence
- capital infusion could improve service accessibility
- non-lawyer influence raises ethical boundary questions
innovation vs consumer protection
- technology platforms promise efficiency gains
- regulatory oversight varies significantly by jurisdiction
market dynamics vs professional values
- multitrillion-dollar legal services market attracts investor interest
- traditional professional model emphasizes independence over efficiency
ai and upl reform
parallel to ownership structure reforms, ai-driven legal tools present similar regulatory challenges. the thomson reuters institute/ncsc ai policy consortium published a white paper in august 202513 proposing three approaches to upl reform.
the consortium - formed 2024, combining thomson reuters (westlaw, cocounsel) with the national center for state courts - approaches upl from both technology and judicial perspectives.
three pathways
path 1: statutory revision
- permit vetted ai tools with registration requirements
- mandate disclosure of ai-powered services
- require accuracy testing mechanisms
path 2: regulatory sandboxes
- controlled testing for ai-driven legal services
- extends existing utah, washington, minnesota models
- data collection on consumer outcomes
path 3: narrow upl definitions
- regulate only those claiming attorney status
- allow ai assistance without attorney representation claims
- focus enforcement on misrepresentation
relationship to alternative structures
both ai/upl and ownership reforms challenge the same premise: that only lawyers can deliver legal services. utah and arizona already test both ownership and technology innovations within their programs. colorado’s pending upl revisions address both domains simultaneously.
the white paper notes state bar associations and supreme courts have limited time to lead these reforms - similar urgency appears in abs debates.
