Oppenheim

What Oppenheim does

Oppenheim is a Budapest-headquartered, full-service Hungarian law firm established in 1989, operating a second office in Vienna since 2012 and employing approximately 70+ legal professionals (partners, counsels, senior associates, associates, junior lawyers, paralegals, and back-office staff) all working on a single floor. The firm provides corporate, commercial, and international legal services to multinational corporations entering or operating in Hungary, domestic large enterprises, and international law firms (e.g., Freshfields Bruckhaus Deringer) requiring local Hungarian counsel on cross-border transactions. Its offering is organized across 13 practice areas — Corporate and M&A, Real Estate, Employment, Intellectual Property, Banking and Finance, Disputes/Litigation/Arbitration, Data Protection, Technology, Cybersecurity, Energy and Regulated Industries, Antitrust/Competition, Projects and Infrastructure, and Artificial Intelligence Law — supported by sector teams covering 13 industries including automotive, energy, financial services, manufacturing, life sciences, technology, and real estate. Specialized service desks include the Korea Desk (launched October 2024 in partnership with JIPYONG LLC) and the Vienna Office, both positioned to capture cross-border Eastern–Western European mandates.

The firm's revenue model is professional services: fees are billed on an hourly basis or under fixed-fee arrangements negotiated per matter, with pricing not publicly disclosed. Go-to-market is partner-led enterprise field sales, with named partners and senior counsel owning key accounts; international law firm referral work (e.g., for Freshfields) is a documented distribution channel. Marketing is driven by thought leadership through multilingual articles, partner contributions to journals (GRUR International, Jogtudományi Közlöny), webinars, and participation in international legal conferences (IBA, ECTA, PTMG). The firm has no proprietary technology platform, no app, no API, and no disclosed funding or external investors — it operates as an independent, privately-held partnership registered with the Budapest Bar Association. Following the September 2025 passing of founding partner Ulrike Elisabeth Rein, leadership continuity is sustained through a deep bench of named partners (Barcza, Fazekas, Fenyvesi, Terényi, Cselédi, Szatmáry, Éless, Kiss, Gass, Bartal, Légrádi, Pintér) and counsel/senior counsel across all practice groups.
