Rivero & Gustafson Abogados

What Rivero & Gustafson Abogados does

Rivero & Gustafson Abogados is a Madrid-headquartered, full-service Spanish law firm founded in 1997 by Sebastián Rivero and John Gustafson, operating as a professional limited company (S.L.P.). The firm is organized into five integrated practice areas — Commercial/Corporate, Procedural/Litigation, Employment/Labor, Tax, and Administrative — each led by a designated partner-coordinator, with cross-departmental collaboration on complex matters such as M&A, due diligence, restructurings, and litigation. It serves companies, entrepreneurs, and individuals requiring Spanish and EU legal advisory, litigation before Spanish courts, and international arbitration coordination.

The firm generates revenue through professional legal fees billed on a quote-based, matter-by-matter basis (hourly rates, fixed fees, or retainers) — no proprietary technology, software products, APIs, or AI/ML capabilities are disclosed. Client acquisition is driven by professional referrals, sustained recognition in international legal directories (Chambers & Partners Europe and Global rankings 2014-2025, Best Lawyers for over a decade), membership in four bilateral chambers of commerce (American, British, Franco-Spanish, Spanish in France), and cross-border coordination through the AWERIAN Alliance (France, Belgium, Germany, Austria) plus bilateral partner firms in USA, Netherlands, Norway, Portugal, UK, Sweden, and Switzerland. The firm operates from a single Madrid office (Avenida de Burgos, 21) with a small, stable team of approximately 11-20 lawyers and administrative staff. No external investment, private equity ownership, or M&A activity is evidenced.
