DLA Piper – the world’s third-largest law firm by revenue – has announced it will dissolve its Swiss verein structure and replace it with a new global holding structure above its US and International LLPs, with closer alignment of strategy, leadership and partner incentives. The decision, confirmed by global chair and co-CEO Frank Ryan in March 2026, ends nearly two decades of operation under a model that Ryan acknowledged had prevented the firm from ever having a unified leadership team.

Among the drivers is a problem that has become increasingly acute in the era of generative AI. The verein structure makes it structurally difficult – and in some cases legally constrained – to consolidate client relationship data, share knowledge management systems or deploy artificial intelligence across member firm boundaries. What once looked like a manageable organisational compromise has become a strategic constraint: the global firm that cannot integrate its data cannot fully integrate its technology.

In a paper written a decade ago – Verein, what is it good for? – this author predicted that the Swiss verein structure adopted by a wave of global law firms would prove structurally unsustainable. The argument was straightforward: the verein asks member firms to behave as one organisation for purposes of brand, client relationships and business development, while remaining entirely separate for the purposes that actually matter to partners – profit, liability and control. That contradiction, it was argued, would eventually tell. What follows is a reckoning.

King & Wood Mallesons: Disintegration in Three Acts

No firm has illustrated the verein thesis more comprehensively – or more painfully — than King & Wood Mallesons. The original paper identified the KWM structure as a cautionary tale in the making, noting the asymmetry between a dominant Chinese arm and a smaller European partnership that had joined expecting to gain much while changing little. The collapse of the former SJ Berwin European arm in January 2017 was, in retrospect, the opening act of a longer drama.

The verein’s ring-fencing worked exactly as designed during that first collapse: the China and Australia arms were financially insulated from the implosion in London and Frankfurt, and the European partnership went into administration while the rest of the structure continued trading. Critics of the original paper might have argued that this proved the verein model’s resilience. They would have been wrong.

In 2023, KWM China announced it would withdraw from the UK, Europe and the Middle East entirely, transferring its operations to Eversheds Sutherland under a cooperation agreement – itself the successor practice built on the rubble of the 2017 collapse. And in December 2025, came the final act: the Chinese and Australian partnerships announced they would end the combination effective 31 March 2026. The Australian arm reverts to the Mallesons brand it carried before the 2012 combination; the Chinese arm becomes King & Wood once more. They will cooperate on a ‘non-exclusive basis’ – the polite formulation for a relationship that is, in practice, over.

The stated reasons – different strategic horizons, geopolitical tensions, a cooling Chinese economy, tightening regulation – are all real. But they are also the predictable consequences of building a global firm out of components with fundamentally divergent interests and then holding them together with a Swiss legal form rather than genuine integration. The verein did not cause those divergences; it merely preserved them in aspic until they became irreconcilable.

Dentons: The World’s Largest Law Firm, Not the Wealthiest

Dentons emerged from a series of combinations in 2013 and spent the following decade in relentless expansion, becoming – by headcount – the world’s largest law firm. The model was the verein taken to its logical extreme: a global brand assembled from dozens of member firms across more than 80 countries, each financially independent, each retaining its own culture and partnerships. It was, in structural terms, the vision the original paper identified as most vulnerable.

The original paper discussed in detail the 2015 disqualification of Dentons in the Gap/RevoLaze patent case before the US International Trade Commission. Chief Administrative Law Judge Bullock found that Dentons could not simultaneously hold itself out as a single global firm to attract business and then claim to be a collection of independent entities to escape conflicts obligations. That tension – the fundamental paradox of the verein – has continued to haunt the firm.

In 2023, Dentons formally unwound its landmark 2015 combination with Dacheng Law Offices, then China’s largest firm, citing Beijing’s tightening cybersecurity, data protection and national security regulations. The separation removed thousands of lawyers from the firm’s headcount and materially reduced its revenue. More tellingly, Project Golden Spike – an ambitious plan to build a comprehensive network of US regional firms through a series of verein combinations, launched in January 2020 – has not yielded a single new US combination since 2021. The architecture of indefinite expansion appears to have stalled.

The financial evidence is stark. In the 2024 AmLaw Global 200, Dentons ranked 13th by revenue – down from 5th in 2023 and 6th in 2022. The firm that once seemed to be redefining the scale of global legal practice is now is punching below its weight.

DLA Piper: Converting the Believer

The most significant development of March 2026 is not a collapse but a conversion. DLA Piper – No. 3 on the AmLaw 100, with $4.2 billion in gross revenue and profit per equity partner of $3.4 million in 2024 – announced it will dissolve its verein structure and replace it with a global holding structure designed to align strategy and partner economics across the US and International LLPs.

The firm’s co-CEO Frank Ryan was explicit about the diagnosis. The verein had meant, in his words, that DLA had ‘never had a single leadership team that together drives the strategic direction of the firm.’ The new structure would allow joint strategic investment and – directly – ‘greater profitability for the partners.’ These are not the words of a firm that has had its hand forced. They are the words of a firm that has concluded, after adopting the verein in 2008, that the original paper was right: the structure imposes a ceiling on what a firm can achieve.

DLA Piper is not in distress. It is profitable, growing and actively recruiting from elite US firms. That makes this announcement more significant, not less. When a firm abandons a structure it has operated since 2008 not because it is failing but because it wants to compete at a higher level, that is the clearest possible signal that the verein has become a liability rather than an asset. One of the world’s largest law firms has bet that BigLaw’s future looks less like a network and more like a true global partnership.

Norton Rose Fulbright: The Verein in Permanent Tension

Not every verein has collapsed or converted – yet. But Norton Rose Fulbright’s recent history illustrates what structural pressure looks like when a firm tries to relieve it without fully committing to the remedy. In September 2024, the firm adopted a new global leadership structure explicitly designed to encourage cross-regional collaboration – an acknowledgement that the verein’s financial separateness was working against the behaviour the firm needed from its partners. The restructuring created a new layer of global management intended to align strategy across the firm’s historically separate regional partnerships. The change was widely interpreted inside the market as an attempt to mitigate the operational fragmentation inherent in the verein model without altering the underlying legal structure – a shift that also coincided with significant turnover within the firm’s global management ranks.

Then, in July 2025, the firm went further: its EMEA and Australian partnerships voted to fully integrate their operations into a single $1 billion business covering 28 offices across 18 jurisdictions – merging their separate profit pools for the first time. The US and Africa remain outside that integration.

The firm is not collapsing. Norton Rose Fulbright remains a major global practice with revenue of roughly $2.4 billion and profit per equity partner of approximately $1.6 million in its most recent publicly reported results. But the July 2025 move is the tell. A firm that genuinely believed the verein was fit for purpose would not have needed to dismantle part of it. What NRF has demonstrated is that the verein’s structural problems are real enough to require partial surgery – but that partial surgery is all that is politically achievable short of the full conversion DLA Piper has now made. The integration effectively creates a regional profit pool inside a structure originally designed to avoid them. It is, in the most literal sense, an attempt to get slightly pregnant.

The contrast with firms operating fully integrated global profit pools remains stark: DLA Piper’s $3.4 million profit per equity partner illustrates the scale of economic alignment that the verein model struggles to deliver.

The Technology Problem Nobody Solved

The financial and cultural tensions within vereins are well documented. Less discussed — but no less corrosive – are the operational failures that accumulate when a firm that presents itself as a single global entity cannot actually function as one. The original paper identified these problems in detail. A decade on, they have not been solved. In most cases, they have got worse.

The most visible casualty is client relationship data. A global firm’s CRM system is, in principle, one of its most powerful competitive tools: the accumulated intelligence about who the firm acts for, in which jurisdictions, at what rates, with what conflicts, and by which partners. In a verein, that intelligence rarely moves freely. The member firms are separate legal entities operating under different regulatory regimes, and the data protection laws governing personal data – client contacts, matter histories, commercial relationships – vary substantially between jurisdictions. The European GDPR framework, in particular, imposes strict conditions on the transfer of personal data across borders that a collection of independent entities cannot easily satisfy. The result is that verein firms nominally operating a single global CRM are, in practice, managing a patchwork of local databases that cannot be fully consolidated or shared. The firm that tells its global client it knows them everywhere is, in a meaningful sense, telling a story.

The original paper noted that Baker McKenzie had historically responded to this problem by housing its entire SAP-based global practice management system in Germany – the jurisdiction with the most stringent data regulations – in order to establish a single compliant baseline. It was a blunt instrument, and it only addressed the storage problem, not the harder question of how data could then be lawfully shared across independent member firms. Most vereins, the paper observed, had probably not solved this problem at all but were simply ignoring it. That observation remains accurate today.

Knowledge management is equally compromised. The institutional value of a global firm’s know-how – its precedents, its matter experience, its sector intelligence, its understanding of how particular judges, regulators and counterparties behave – depends entirely on that knowledge being searchable and accessible across the firm. In a verein, it is not. Each member firm maintains its own knowledge repositories under its own systems with its own access controls, and the regulatory barriers to sharing work product across jurisdictions add further friction. A client instructing a verein firm in London on a cross-border matter cannot assume that the relevant experience from the firm’s Singapore or Chicago office is systematically available to the team advising them. In a fully integrated firm, it would be.

The arrival of generative AI has sharpened this problem considerably. Firms are now deploying AI tools across their practices for document review, research, drafting and client-facing analysis. The value of those tools scales with the quality and breadth of the data on which they are trained and to which they have access. A firm that cannot consolidate its matter data, its precedent library or its client intelligence across member firm boundaries cannot train or deploy AI effectively at a global level. It is competing in the AI era with one hand tied behind its back – and that hand is the verein structure itself.

These are not problems that better technology can solve within the verein framework. They are structural. The legal barriers to data sharing between independent entities in different jurisdictions are not a systems integration challenge; they are a fundamental consequence of the member firms being, in law, separate organisations. No amount of investment in middleware, API connectivity or cloud infrastructure changes that underlying reality. The only solution is the one the original paper recommended: stop being separate organisations.

The arrival of generative AI has therefore turned what was once an organisational inconvenience into a strategic constraint. The firms now building proprietary AI capabilities are those able to train models on the full depth of their matter history, precedents and client intelligence across the entire partnership. A verein cannot easily do that. Its data is legally fragmented, operationally siloed and culturally guarded by separate profit pools. In the AI era, scale is no longer measured only by headcount or office count; it is measured by the volume and integration of usable data. On that metric, the verein structure does not merely slow firms down. It structurally disqualifies them from competing on equal terms.

The global firm of the AI era will look less like a federation and more like a data platform. The verein was designed for the opposite world.

The Broader Context: The Merger Wave the Vereins Missed

While the vereins have been retreating, the firms prepared to accept the costs of genuine integration have been reshaping the competitive landscape. Allen & Overy and Shearman & Sterling completed a $3.5 billion transatlantic merger in 2024 – a full integration, not a verein. Hogan Lovells is combining with Cadwalader, Wickersham & Taft to create a $3.6 billion firm. Winston & Strawn is completing a full merger with Taylor Wessing. Perkins Coie and Ashurst have announced their combination. At least sixteen major deals have reportedly been announced for completion in 2026 alone.

The pattern is clear. Firms are accepting of the need for that ‘almost irrevocable commitment’ that the original paper identified as the defining characteristic of a true merger – and the defining weakness of the verein as an alternative to it. The pain, as Herbert Smith Freehills demonstrated when it merged fully with the Australian firm Freehills in 2012, is temporary. The benefits of genuinely being one firm are permanent.

Conclusion: The Emperor’s New Clothes

The original paper concluded with a prediction: vereins are doomed to failure unless a Damascene conversion takes place and persuades member firms to undertake a proper merger; otherwise, the cultural, organisational, technological and regulatory issues and the underlying economic self-interest will cause them to break up into their constituent parts, or some combination thereof. It also noted, more sharply, that if the judges got there first and pierced the verein veil, ‘the emperor will truly have no clothes.’

The emperor’s wardrobe is now visibly depleted. KWM combination has dissolved. Dentons has retreated on two fronts and fallen from 5th to 13th in global revenue rankings in n the AmLaw Global 200 revenue rankings in two years. DLA Piper has decided, from a position of strength, that the structure is no longer fit for purpose and discarded it. Norton Rose Fulbright has partially dismantled its own verein – integrating its EMEA and Australian profit pools while leaving the US separate – a half-measure that confirms the diagnosis without completing the cure.

The fundamental problem the original paper identified has not changed. A verein asks law firms to behave as one organisation in the areas that benefit clients and the firm’s external image, while remaining separate organisations in the areas that matter to partners. That contradiction generates the conflicts, the cultural tensions, the data-sharing problems, the financial asymmetries and the strategic paralysis that have now produced a decade of visible structural failure across the model’s most prominent exemplars.

Baker & McKenzie, which adopted the verein form in 2004 as an evolution of an already-integrated global franchise, remains the possible exception – a firm with sufficient pre-existing cultural and commercial cohesion to make the structure function. It is, as the original paper noted, a different animal from the firms that used the verein as a device to engineer speedy combinations they were not ready to commit to fully.

For those firms, the verdict is now available. It took a decade. But it arrived.
