The UK’s largest litigation practices increased collective revenue by over 50% in the past five years, while partnership headcount has surged by more than 75%. As firms push to meet increasingly ambitious revenue targets, the disputes market is intensifying. This acceleration is most pronounced in the UK upper mid-tier, where five firms stand out for the scale of their partner investment, each pursuing a distinct route to growth.
Addleshaw Goddard , Fieldfisher , Mishcon de Reya LLP , Taylor Wessing and Weightmans have all more than doubled the size of their UK litigation partnerships since 2021. Each has increased disputes revenue in the process. Yet across the group, litigation’s share of UK revenue has either fallen or remained flat. This is not retrenchment. Disputes is being used as an engine for diversification and expansion, not as a counter-cyclical refuge. Each of these firms are pursuing turbo-charged growth strategies as a new global order takes shape around them.
Taylor Wessing is a clear outlier. The firm has long had a strong litigation platform, but its acquisition by Winston & Strawn heightens the need to demonstrate that top-tier capability from London. Exiting the European verein and pivoting toward the US removes structural constraints on its ambition, removing conflicts and potentially strengthening the combined firm’s position on a transatlantic stage.
Our data suggests that repositioning is already well advanced. Since 2021, UK litigation revenues have increased by 108% to £102.1m, while the firm has doubled its UK litigation partnership to 44 partners without sacrificing productivity. Revenue per litigation partner (RPP) rose by 4% to £2.3m, underlining that growth has been selective, revenue-attached and focused on strengthening in London.
Addleshaw Goddard and Fieldfisher, by contrast, are pursuing growth strategies across Europe. Together, this pair have opened 17 European offices since 2020. At Addleshaw Goddard, that expansion is pinned to its ambition to hit £1bn in revenue by 2030, a target that will require 81% growth in the next four years. For context, the firm increased revenue by 71% since 2021. Disputes has been a central recipient of that investment. Addleshaws now has 85 UK litigation partners, up from 41 five years ago, and has grown by 36% to £105.3m over the same period. However, litigation’s share of firmwide revenue has edged down slightly, from 26% in 2021 to 23% in 2025. Rather than signalling a loss of focus, this shows disputes being scaled to keep pace with firmwide expansion, operating alongside other core practices rather than as a dominant profit engine. This approach aligns with managing partner Andrew Johnston’s emphasis on tightening performance across the whole platform, rather than siloed growth. Whether that trajectory ultimately translates into a merger remains uncertain, but the firm is clearly bolstering the foundations.
Fieldfisher’s growth trajectory is similarly European-focused, but it is entering a period of integration after expanding its continental platform. Phase two of the strategy (2025–2030) is centred on its One Europe programme, which is all about operational and client integration across its international network. The disputes practice has been scaled, and the firm now has 83 UK litigation partners, up from 27 in 2021, which has led to a 50% rise in litigation revenue to £100.8m. And yet, the proportion of UK revenue derived from the disputes practice has been flat, averaging around 40% since 2021. Revenue per litigation partner, meanwhile, has declined as the firm expanded. The challenge for managing partner Rob Shooter will be to convert that scale into improved productivity during the integration phase. As with Addleshaw Goddard, disputes is being calibrated to support regulatory, technology and sector-led mandates across Europe, rather than to outgrow the platform it supports.
Mishcon de Reya is following a similar pattern, broadening practice mix while continuing to invest in a dominant disputes platform. The firm is deliberately recalibrating how that strength is deployed and perceived. Under its Vision 2030 strategy, Mishcon has pursued targeted international expansion, doubled down on real estate and disputes, and is building a global employment platform. The objective is to move beyond a predominantly claimant-side profile and position disputes as a more balanced offering. The data suggests this approach is gaining traction. Since 2021, litigation partner headcount has more than doubled to 111, while UK litigation revenue has increased by 32% to £161.3m. Over the same period, disputes’ share of UK revenue has fallen from 65% to 53%, reflecting faster growth in other practices as the firm deliberately rebalances its platform.
Weightmans arguably has the greatest distance to travel to achieve its stated ambitions, but also the clearest rationale for scaling disputes. With £188.4m revenue in 2025, no European offices and a stated ambition to reach Top 30 UK200 status by 2030, the firm must ultimately more than double in size. Litigation is central to that strategy. Since 2021, the UK litigation partnership has expanded from 60 to 186 partners, while UK disputes revenue has grown to £97m, accounting for 67% of UK revenue (£144.8m).
This is a scale play. Disputes is being built as nationally embedded infrastructure to support volume, panel work and repeat institutional mandates. But to move beyond its insurance roots and build meaningful strength in public-sector and owner-managed business work, that platform will need to extend much further.
The constraint is now one of limits. Having already pulled the most aggressive organic levers available on talent and revenue, Weightmans is close to the practical ceiling of organic growth in disputes without further RPP dilution or operational strain. At that point, a merger becomes the most efficient next step — not a sign of strategic failure, but a logical extension of the strategy already in motion. These firms show that the disputes practice is no longer a defensive silo but a strategic engine. From integration to scale, the practice does the heavy lifting for the entire platform. The next phase of competition will be won by firms that treat disputes as a proactive lever for growth, not a position to be protected.
Prosperant’s H1 Disputes Outlook 2026 brings together the intelligence litigators need to steer their practices through a period of profound change. We have charted the financial trajectories of the major UK and global litigation players, followed the partner hires and office movements that signal strategic intent, and analysed arbitration and court trends across centres of influence. Together, these insights offer a clear, evidence-based view of what comes next. Our aim is to equip disputes leaders to navigate uncertainty with confidence and purpose. Those who rise to this moment will shape not only their own practices, but the future direction of their firms.
