Arizona and the UK: the next ABS jurisdictions

Two jurisdictions on opposite sides of the Atlantic are quietly rewriting the ownership rules for legal services, and the consequences for capital, competition, and firm structure are only beginning to surface. Arizona's regulatory sandbox, launched in 2021, removed the prohibition on non-lawyer ownership of law firms operating within its programme. The United Kingdom's alternative business structure regime, introduced under the Legal Services Act 2007 and administered by the Solicitors Regulation Authority, has been operational for over a decade but is entering a new phase of commercial maturity. Together, these two jurisdictions represent the clearest live evidence that the traditional partnership model is not the only viable architecture for delivering legal services at scale. For operators, funders, and law firm leaders thinking carefully about legal asset management, the question is not whether these changes matter. It is how quickly the structural implications will compound.

What the market usually gets wrong

The dominant misconception about alternative business structures is that they are primarily a regulatory curiosity, relevant mainly to consumer-facing legal services providers or to firms that have already decided to seek external investment. That framing is too narrow, and it causes practitioners and operators alike to underestimate the scope of what is actually changing.

The alternative business structure, in both its UK form and its functional equivalent in Arizona's sandbox, is not simply a permission to accept outside capital. It is a permission to reorganise the entire operating layer of a legal business. That includes how profits are distributed, how management authority is allocated, how technology investment is structured, how risk is priced, and how the firm positions itself relative to adjacent professional services markets. When commentators focus exclusively on the investment angle, they miss the deeper point: the ABS framework changes what a law firm is allowed to be, not just who is allowed to own it.

In the UK, the early years of the ABS regime were dominated by a relatively small number of high-profile entrants, including insurance-backed providers and consolidated personal injury practices. The impression formed in some quarters was that ABS status was a tool for volume commodity work rather than a structural option for sophisticated commercial practices. That impression has not aged well. The range of entities now holding ABS licences in England and Wales spans a considerably broader set of practice types, and the regulatory infrastructure has matured to the point where the licence itself is no longer the primary barrier to entry.

In Arizona, the sandbox model introduced a different kind of misconception. Because the programme is framed as an experiment, with participating entities subject to ongoing reporting obligations and regulatory oversight, some observers have treated it as provisional or fragile. In practice, the programme has attracted a meaningful cohort of participants and has generated sufficient operational data to inform policy discussions in other US states. The experimental framing understates the durability of what Arizona has built.

What actually changes at the operating layer

When a legal business moves from a traditional partnership structure to an alternative business structure, the most significant changes are not visible on the firm's letterhead. They occur in the governance documents, the capital table, the management reporting lines, and the incentive structures that shape day-to-day decisions.

In a conventional partnership, profit distribution is typically tied to equity participation, and equity participation is typically restricted to qualified lawyers. This creates a structural ceiling on the firm's ability to retain and incentivise non-lawyer talent, to invest in technology without immediate partner buy-in, and to raise capital for growth without diluting the partnership in ways that partners find politically difficult. The ABS framework removes that ceiling by allowing the firm to separate ownership from practice rights.

For operators thinking about this from a legal asset management perspective, the practical consequence is that an ABS-licensed entity can be capitalised and governed more like a professional services business than like a regulated partnership. That means it can carry debt in a more structured way, it can issue equity to non-lawyer executives, it can create incentive pools for technology and operations staff, and it can present a more legible investment case to external capital providers.

Arizona's sandbox adds a further dimension. Because participating entities are not required to be law firms in the traditional sense, the sandbox has attracted entrants whose primary business model is not legal practice but legal technology, legal process outsourcing, or integrated professional services. These entrants are not trying to become law firms. They are trying to deliver legal outcomes within a regulated framework that gives their clients the protections associated with legal practice. That is a materially different proposition, and it has significant implications for how incumbents in both the UK and the US think about competitive positioning.

The workflow implications are equally significant. An ABS or sandbox entity can invest in process automation, artificial intelligence-assisted document review, and integrated case management systems without having to justify those investments through the lens of partner profit per equity point. The capital allocation logic is different, and that difference compounds over time. Firms that have operated under ABS structures for several years have had the opportunity to build technology stacks and operational capabilities that would have been difficult to fund under a traditional partnership model.

Commercial consequences for firms, funders, and operators

The commercial consequences of the ABS and sandbox frameworks are distributed unevenly across the market, and the distribution is not always intuitive.

For established UK law firms that have not pursued ABS status, the primary risk is not that a licensed competitor will immediately undercut them on price. It is that the licensed competitor will invest in operational capabilities over a sustained period and emerge with a structurally lower cost base and a more scalable delivery model. That is a slow-moving threat, but it is a real one, and the firms most exposed are those in the mid-market where margin pressure is already acute.

For funders and investors, the ABS framework opens a category of investment that was previously unavailable. Direct equity participation in a legal services business, with the governance rights and information rights that equity typically carries, is a fundamentally different proposition from litigation funding or law firm lending. It allows investors to participate in the upside of a well-run legal business rather than simply financing a specific portfolio of claims or providing working capital against receivables. The risk profile is different, the return profile is different, and the due diligence requirements are different. Investors who have not yet developed the capability to assess legal businesses as operating companies will find themselves at a disadvantage as this market develops.

For operators within legal businesses, including chief operating officers, chief financial officers, and heads of legal operations, the ABS framework creates both an opportunity and an obligation. The opportunity is to make the case for structural reform from within, using the regulatory permission as a catalyst for governance and capital conversations that would otherwise be difficult to initiate. The obligation is to understand the regulatory requirements well enough to manage the compliance burden that comes with ABS status, which is materially more demanding than the compliance obligations of a traditional firm.

In Arizona, the commercial consequences are still emerging, but the early evidence suggests that the sandbox has been most commercially significant for entities that were already operating at the intersection of legal services and technology. For those entities, the sandbox provides a regulatory home that allows them to formalise and scale activities that were previously conducted in a legally ambiguous space. That formalisation has commercial value in its own right, because it allows the entity to make representations to clients about the regulatory framework governing its work.

Anyone seeking a broader grounding in how these structural shifts connect to capital strategy and portfolio thinking should explore the legal asset management section of this site, which addresses the operating and investment dimensions in greater depth.

Where the market is likely to move next

The trajectory in both jurisdictions points toward consolidation and professionalisation rather than fragmentation. In the UK, the ABS market has already seen a wave of consolidation among consumer-facing providers, and there are early signs that similar dynamics are beginning to play out in commercial practice areas. The firms that have built scalable operating models under ABS structures are better positioned to acquire smaller practices and integrate them efficiently than traditional partnerships, which face structural obstacles to post-merger integration.

In Arizona, the sandbox model is being watched closely by regulators in other US states. Several states have initiated their own reform processes, and the policy debate has shifted from whether non-lawyer ownership should be permitted to how it should be regulated. That shift is significant. It suggests that the question of regulatory permission is closer to being settled than the current patchwork of state rules might imply, and that the near-term debate will focus on the design of oversight frameworks rather than the principle of reform.

At the international level, the interaction between the UK ABS regime and the Arizona sandbox is itself commercially interesting. Entities that have developed operating models under one framework are well placed to adapt those models for the other, because the underlying logic of separating ownership from practice rights is common to both. Cross-jurisdictional legal businesses that can operate under ABS or equivalent frameworks in multiple markets will have structural advantages over competitors that remain confined to traditional partnership models.

For those interested in how these jurisdictional developments connect to broader questions of legal market structure and investment strategy, the writing section of this site contains a range of related analysis.

What this means in practice

The practical implications for operators and decision-makers are more immediate than the pace of regulatory change might suggest. The UK ABS regime is not a future development. It is an existing framework with a functioning licence market, a body of regulatory precedent, and a growing cohort of licensed entities whose operational experience is now available as a reference point. Arizona's sandbox is similarly operational, with participating entities generating real commercial data about what works and what does not.

For law firm leaders, the immediate practical question is not whether to pursue ABS status but whether the firm's current governance and capital structure is appropriate for the competitive environment it will face over the next decade. That question does not require a firm to conclude that ABS status is the right answer. It does require the firm to engage seriously with the structural options that the regulatory framework makes available, rather than defaulting to the partnership model because it is familiar.

For funders and investors, the practical question is whether their current due diligence and portfolio management capabilities are adequate for direct equity participation in legal businesses. The answer for most investors is that they require further development, and the time to build that capability is before the market for ABS equity becomes competitive rather than after.

For operators and legal operations professionals, the practical question is how to use the ABS framework as a lever for internal reform. The regulatory permission to restructure is a resource, and like any resource it has more value when it is deployed deliberately than when it is allowed to sit unused.

The alternative business structure is not a solution to every problem in legal services, and neither is Arizona's sandbox. But both represent genuine structural options that are available now, in operating jurisdictions, with real regulatory frameworks and real commercial precedents. Operators who engage with them seriously will be better positioned than those who treat them as peripheral developments. To explore how these themes connect to broader capital and governance strategy, the about section of this site provides further context on the analytical approach that informs this work.
