Osterling Abogados

What Osterling Abogados does

Osterling Abogados is a full-service Peruvian law firm founded in 1980 in San Isidro, Lima, structured as a Civil Law Partnership (ESTUDIO OSTERLING S.CIVIL DE R.L.). The firm operates from a single headquarters in Lima and provides legal advisory and dispute-resolution services across 17 practice areas, including Corporate/M&A, Arbitration, Compliance, Construction, Dispute Resolution, Labor and Human Resources, Insurance and Reinsurance, Intellectual Property and Consumer Law, Tax, TMT (Telecoms/Media/Technology), Real Estate, Regulatory and Lifesciences, Data Protection, Public Law, Fashion Law, Immigration, and Occupational Health and Safety. It serves a mix of domestic and foreign enterprise clients across mining, insurance, pharmaceuticals, cosmetics and fashion (notably Armani, Yves Saint Laurent, L'Oreal), food and beverage, real estate, technology, and telecommunications, with selective cross-border mandates touching Chile and Ecuador. The firm does not produce technology products or operate a proprietary software platform; its offering is professional legal services delivered by partners and associates with specialized postgraduate training.

The firm follows a partner-led, sales-led go-to-market model built on professional reputation, international directory rankings (Chambers and Partners, Legal 500, WTR 1000, Leaders League, IP Stars), and longstanding client referrals. It employs between 51 and 100 people, led by principal partners Arturo Tello (Intellectual Property and Competition) and Ary Alcántara (Labor and Human Resources), with Madeleine Osterling, Ximena Souza Ferreira, Gabriel Loli, Joyce Cieza, José Del Castillo, Mauricio Martínez, Rabeth Pareja, Scilia Flores, and Angello Rivera as additional partners (the last two promoted in November 2024). Revenue derives from professional legal fees billed through hourly rates, fixed fees per matter, and contingent or success-fee arrangements in litigation and arbitration; precise figures are not publicly disclosed.

Osterling is independently owned with no parent company, no private-equity backing, and no disclosed funding rounds. Its competitive position rests on four-plus decades of continuous operation, deep relationships with Peruvian regulators (INDECOPI, SUNAT, SBS, SUNAFIL, DIGESA, DIGEMID), and alumni flow into and out of those agencies. The firm is a member of the Insuralex international insurance-law network and has pursued recent growth through the build-out of TMT, Data Protection, Fashion Law, Compliance, and Lifesciences practices, alongside ongoing recognition by global legal directories.
