What Arthur Cox does
Arthur Cox LLP is a Dublin-headquartered, full-service corporate and business law firm founded in 1920, operating as a private limited liability partnership under Irish law. The firm serves corporates, financial institutions, multinationals, and public companies across Ireland, the UK, and the US, with offices in Dublin (HQ at Ten Earlsfort Terrace), Belfast, London, New York, and San Francisco. Its practice spans M&A, corporate finance, private equity, tax, financial regulation, capital markets, real estate, employment, dispute resolution, and sector-specific work in technology, life sciences, energy, and infrastructure. The firm is consistently ranked at the top of Irish and European legal directories (Chambers, Legal 500, IFLR, Who's Who Legal) and was named Ireland Law Firm of the Year at multiple awards in 2021, 2023, 2025, and 2026.
The firm operates a partner-led, enterprise go-to-market model. Revenue is generated through professional legal services billed on a matter-by-matter basis (hourly, fixed-fee, or transaction-based), with no publicly disclosed pricing and no intermediaries. Distribution is entirely direct via partners and multidisciplinary legal teams, supported by a content-driven marketing engine (knowledge portal, insights blog, CPD on-demand portal, podcasts, events, and sponsorships). Its technology posture is led by a recently appointed Chief Technology Officer, Jennifer Ward, who manages the AI strategy and an internal 'innovation lawyer group'; Gen AI is being explored in controlled use cases such as DSAR data review, with the firm itself noting cautious adoption. Adjacent offerings include the 'Evolve - Innovating Legal Services' program, a Legal Tech Services module, and an ESG Hub.
Arthur Cox has no parent company, no external institutional shareholders, and is independently owned by its partners. Headcount sits in the 501-1,000 range, and recent strategic activity has focused on leadership renewal (Chair Ailish Finnerty in 2025, Managing Partner Geoff Moore reappointed in 2023), US West Coast expansion via the San Francisco office, and the buildout of AI and innovation capacity under the CTO. The firm advised on 20 of Finance Dublin's Deals of the Year 2026, illustrating sustained dominance on the largest Irish transactions.
