Bar associations, regulators and the limits of competition

In 2007, England and Wales passed a law that let non lawyers own law firms. In most of the United States, that same structure remains illegal today, nearly two decades later. Same industry, same basic service, two completely different competitive universes. The difference wasn't demand, technology, or client preference. It was regulation.

That gap is the subject of this lesson: how bar associations and regulators don't just referee competition in legal services, they decide who is even allowed onto the field.

The gatekeepers: who actually controls market entry

In most industries, competition law (antitrust in the US, competition policy in the EU) worries about firms getting too big or colluding. In legal services, the more fundamental question is upstream: who is allowed to practice law at all, and who is allowed to own a firm that practices law.

Two types of gatekeepers matter here:

State bar associations (US): Each US state has its own bar, and each bar enforces its own version of Rule 5.4 of the ABA (American Bar Association) Model Rules of Professional Conduct. Rule 5.4 bars non lawyers from owning equity in law firms or sharing legal fees with them, with narrow exceptions. This rule exists in nearly every US state.

The SRA (Solicitors Regulation Authority) in England and Wales: This is the regulator for solicitors, operating under the Legal Services Act 2007. Unlike US bars, the SRA permits Alternative Business Structures (ABS), firms that can have non lawyer owners, outside investors, or even be publicly listed.

The practical effect: in London, a company like the Co-operative Group could (and did) offer legal services under an ABS license. Publicly traded firms like DWF Group listed on the London Stock Exchange. In New York or California, that kind of ownership structure would violate bar rules and risk disbarment for any lawyer involved.

Why the rule exists, and who it protects

Rule 5.4 is usually justified on professional independence grounds: if a non lawyer owns equity in a firm, the argument goes, that owner might pressure lawyers to prioritize profit over client duty or ethical obligations.

That's the official rationale. But look at the effect: it also insulates incumbent law firm partners from a very specific competitive threat, outside capital.

Without outside investment, a law firm can only grow as fast as its partners can self-fund or borrow against future partner earnings. That caps how big and how fast challengers can scale. It also blocks a whole category of potential entrants: legal tech companies, private equity, even retailers, from directly owning firms and competing on price or delivery model.

Compare this to the ABS-enabled UK market, where:

• Slater and Gordon became one of the first law firms globally to list on a public stock exchange (Australia, 2007, later expanding into the UK), using public capital to acquire smaller personal injury practices.
• DWF Group listed on the London Stock Exchange in 2019, using public markets the way a normal services company would.
• Insurers and claims management companies gained more direct routes into legal service delivery.

The US market has none of this. Legal tech companies like LegalZoom built billion dollar businesses, but had to carefully structure themselves as *not* practicing law, selling document templates and referral services rather than legal advice itself, precisely to stay on the right side of unauthorized practice of law (UPL) statutes.

The exception that proves the rule: Arizona and Utah

Interestingly, US regulation isn't monolithic. Arizona eliminated Rule 5.4 entirely in 2021, becoming the first US state to allow non lawyer ownership of law firms. Utah launched a regulatory "sandbox" in 2020 (a supervised space where alternative business models can be tested under regulator oversight) allowing similar experimentation.

The result was immediate: companies began forming Alternative Business Structures in Arizona that would be illegal in California or New York. This created a real world natural experiment, and it shows the rule isn't some inevitable feature of "legal services" as an industry. It's a specific policy choice, made state by state, that can be unmade.

You can track ongoing state level reform efforts through the American Bar Association's own resource center on regulatory innovation, which documents state by state divergence in real time.

Who wins and who loses from these rules

This is where the "players and power" lens matters most.

Incumbent law firm partners are the clearest beneficiaries of ownership restrictions. Restricting outside capital limits the size and aggressiveness of new entrants. It also preserves the partnership model's control over profits, since equity partners capture the value the firm generates rather than splitting it with outside shareholders.

Clients, particularly price sensitive ones (individuals needing a will, small businesses needing routine contracts) arguably lose out. Less capital in the market means less investment in the kind of process efficiency, technology, and scale that lowers prices in most other service industries.

Legal tech and legaltech-adjacent companies (Clio for practice management, Ironclad for contract lifecycle management, Harvey for AI-assisted legal research) have had to build businesses that sell *tools to lawyers* rather than *legal services directly*, precisely because direct ownership or fee-sharing with law firms is restricted in most US jurisdictions. That shapes where value accumulates: software margins go to tech vendors, but legal service delivery margins stay locked inside law firm partnerships.

Regulators themselves hold enormous quiet power. The SRA's decision to permit ABS didn't just tweak competition, it created entirely new categories of competitor overnight. A regulator choosing whether to keep or loosen a rule like this is arguably making a more consequential competitive decision than any single firm's strategy.

The bigger pattern: regulation as market structure

Step back, and the legal sector illustrates something true across many professional services: competition doesn't happen in a neutral arena. The rules about who can own, who can practice, and who can share fees are themselves the terrain on which competition happens.

This matters for anyone assessing legal services as a market, whether as an investor, a legal tech founder, or a corporate buyer of legal services. The relevant question isn't just "who has the best product or lowest price." It's "what does the regulator currently allow, and is that likely to change."

Consider also the EU, where regulation varies country by country rather than under one unified rule. Germany maintains strict ownership rules similar to the US model. The Netherlands has moved further toward liberalization. This patchwork means a pan-European law firm or legal tech company faces a genuinely different competitive rulebook depending on jurisdiction, unlike, say, a bank operating under a more harmonized EU framework.

What to watch going forward

A few signals worth tracking if you want to stay current on this in 2026 and beyond:

• Whether more US states follow Arizona and Utah's lead on loosening ownership rules
• Whether AI-driven legal tools intensify pressure on UPL statutes, as tools like AI legal assistants blur the line between "software" and "practicing law"
• Whether large accounting and consulting firms (which already offer legal services in ABS-friendly markets under multidisciplinary practice models) push further into US markets if rules shift

Key Takeaways

• Bar associations and regulators like the SRA don't just enforce standards, they determine who is legally allowed to own and compete in the legal services market, which is a far more powerful lever than pricing or marketing rules.
• ABA Model Rule 5.4 blocks non lawyer ownership across most of the US; England and Wales' Legal Services Act 2007 permits it through Alternative Business Structures (ABS), creating fundamentally different competitive landscapes for the same industry.
• Arizona (2021) and Utah's regulatory sandbox show these rules are policy choices, not fixed features of the industry, and can change state by state.
• Restrictions on outside capital tend to protect incumbent law firm partners' control over profits while limiting the scale and pricing pressure that outside investment could bring to clients.
• Legal tech companies operating in the US have had to build "tools for lawyers" business models rather than direct legal service delivery models, a structural consequence of ownership and fee sharing restrictions rather than a market preference.
