What Ronan Daly Jermyn does

RDJ LLP (formerly Ronan Daly Jermyn) is a leading Irish corporate law firm headquartered in Cork with additional offices in Dublin and Galway, employing 110+ lawyers and 251-500 total staff. Founded in 1982 and rebranded to RDJ LLP in 2022, the firm delivers legal services across twelve practice areas including Corporate and Commercial (M&A, corporate finance, commercial contracts), Banking and Finance, Dispute Resolution, Employment Law, Real Estate, Regulatory and Compliance, Tax, ESG & Sustainability, Construction, Insolvency and Corporate Restructuring, Cyber-Security Incident Response, and Technology and Innovation.

The firm serves three primary client segments — multi-national corporations, established and growing Irish companies (including startups), and leading Irish and international insurance firms — plus institutions and not-for-profit organisations. Recent mandates demonstrate cross-sector breadth: Cummins Sports examinership (insolvency/restructuring), JCD Group / CWS Workwear commercial lease (real estate), Peter Curran Electric / Wolseley acquisition (cross-border M&A in renewable energy distribution), Gigi Supplements seed round (venture financing), and Wayleadr's acquisition by a US-led PE consortium (cross-border technology M&A). Revenue is generated through professional services engagements quoted per matter under engagement letters, with no public pricing schedule; multi-year client relationships are common.

RDJ holds a Band 1 Chambers ranking for Insurance Dispute Resolution and is recognised across 17 practice areas in Legal 500 2026 and 11 in Chambers Europe 2026, with 45 individual lawyer rankings. The firm maintains exclusive TerraLex membership in Ireland (providing client access to 200+ jurisdictions), ISO 27001 certification since 2017, FSQS registration, Q9000 Gold Standard, and is Ireland's first B Corp certified law firm. In 2025 the firm deployed Legora's legal AI platform firmwide as part of a digital transformation, positioning productivity gains through third-party AI tooling rather than proprietary model development.
