Kelemen, Mészáros, Sándor and Partners Law Firm

What Kelemen, Mészáros, Sándor and Partners Law Firm does

Kelemen, Mészáros, Sándor and Partners Law Firm (Kelemen, Mészáros, Sándor és Társai Ügyvédi Iroda) is a Budapest-based, full-service Hungarian law firm founded in 1993. The firm provides legal representation and counsel across corporate law, business law, international transactions, claim enforcement, civil and commercial litigation, arbitration, real estate, public-private partnerships, environmental law, public procurement, competition law, IT law, labor law, energy law, industrial property, administrative law, insurance law, and EU law. Services are delivered in Hungarian, English, and German, with a multilingual website (also in Russian and Arabic) supporting international client access.

The firm operates from a single office in central Budapest and consists of 11 listed team members, including 10 professional attorneys/professors and one trainee lawyer. Its revenue model is professional services fees billed under quote-based engagements and ongoing permanent commissions. A central revenue activity is claim enforcement — the firm is currently executing approximately 10,000 claims for several financial services and factoring companies — alongside continuous legal counsel to Hungarian and international corporates. Pricing is not publicly disclosed and varies by matter complexity and practice area.

Distribution is anchored by direct client relationships and six international partnerships (Interlegal since 2005, Dacheng Law Offices since 2011, Hussain Lootah & Associates since 2013, Greenberg Traurig LLP since 2018, LARMO since 2021, Freeh Sporkin & Sullivan LLP since 2021) that provide cross-border referral capability across 45+ countries. The firm's competitive differentiation rests heavily on the academic credentials of its partners, who include multiple university professors with DSc degrees from the Hungarian Academy of Sciences, a Széchenyi Prize laureate (Prof. Dr. Gábor Hamza), a former Member of Parliament, and a past president of the Interlegal Network (Prof. Dr. Boóc Ádám). The firm is privately held by its founding partners, with no external investors, public listing, or disclosed revenue.
