Addleshaw Goddard and Fieldfisher Choose Harvey and Legora as Legal AI Adoption Race Accelerates Across City Firms
Addleshaw Goddard has signed a firmwide partnership with Harvey, giving more than 3,400 lawyers and staff across its European, Middle East and Asia offices access to the AI platform, while Fieldfisher has selected Legora for its 1,400 lawyers and business services professionals following a six-week pilot across UK and European offices. Addleshaw's managing partner Andrew Johnston described the Harvey deal as 'the most significant technology transformation in AG's long history as an innovator', with the firm committing to co-develop features alongside Harvey's product teams rather than simply deploying the platform firmwide. Kerry Westland, Addleshaw's Head of Innovation, cited Harvey's 'matter spaces' capability as a key differentiator and confirmed the firm will not run a dual Harvey-Legora stack. Fieldfisher's rollout will be led by its AI hub at Fieldfisher X in Berlin. The decisions extend a widening divide in legal AI platform allegiances: Harvey is already deployed at A&O Shearman and Slaughter and May; Legora is integrated at Linklaters; and Freshfields has partnered with Anthropic. Hogan Lovells Cadwalader made the unusual move of adopting both Harvey and Legora simultaneously, arguing no single AI solution can cover the demands of a modern international law firm.
Why this matters
The pace at which Magic Circle and Silver Circle firms are committing to exclusive or near-exclusive AI platform partnerships signals that the market is consolidating fast, late movers risk inheriting whichever platform their peer group has already shaped. Addleshaw's co-development commitment is a step beyond procurement: the firm is effectively contributing to the product roadmap, raising questions about IP ownership in jointly developed features and competitive advantage if those features eventually ship to all Harvey clients. Fieldfisher's Berlin-led rollout reflects the cross-border integration challenge, where AI governance, data-residency rules and bar-specific compliance requirements vary materially across jurisdictions. The Hogan Lovells Cadwalader dual-platform decision sits at the opposite end of the spectrum and will be watched closely as a test of whether multi-vendor AI strategies generate efficiency gains or coordination overhead.
On the Ground
Technology transactions and commercial contracts work is immediately activated: firms adopting AI platforms need licensing agreements, data processing agreements and, where co-development is involved, IP assignment or joint-ownership provisions. Privacy and data-governance lawyers must assess whether client data fed to AI platforms satisfies SRA obligations and cross-border transfer requirements. Risk and professional responsibility teams will be involved in drafting internal AI use policies and training protocols. A trainee on this matter would likely be asked to review a Harvey or Legora master services agreement, flag data-processing and confidentiality provisions, and prepare a jurisdiction-by-jurisdiction compliance checklist covering GDPR, the EU AI Act and applicable bar rules.
