What DNM - DIOGO, NETO, MARQUES & ASSOCIADOS - SOCIEDADE DE ADVOGADOS, RL does

DNM - Diogo, Neto, Marques & Associados - Sociedade de Advogados, RL is a Portuguese law firm constituted in November 2002 as a Sociedade de Advogados RL (a Portuguese limited liability law partnership). Although formally founded in 2002, the firm's origins trace to the early 1990s collaboration between founders Mário Diogo and Paulo Neto, with Jorge Marques joining as a partner in the late 1990s. The firm operates from two offices: its headquarters at Avenida Heróis do Ultramar 52 in Pombal and a secondary office at Avenida Duque de Loulé 95 in Lisbon. It employs approximately eight people, comprising six partners (Mário Diogo, Paulo Neto, Jorge Marques, Joana Mendonça, Vera Lúcia Santos, and David Pereira) and supporting solicitors and legal assistants.

The firm delivers advisory, litigation, and consultancy services across 36+ practice areas spanning civil, corporate, labour, family, criminal, administrative, tax, real estate, immigration, intellectual property, M&A, insolvency, competition, environmental, energy, and EU law. Services are delivered in Portuguese, English, Spanish, and French to serve private individuals, corporate clients, and public entities, with a particular focus on supporting foreign investors in the Pombal region. Underlying technology is conventional: a multilingual CMS website and Microsoft Outlook-based online appointment booking. International reach is delivered through membership in AEA International Lawyers Network (where partner Paulo Neto serves as Vice-President) and as a founding member of Justinian Lawyers, providing referral capacity across 55+ countries.

DNM generates revenue through professional-services billings on a quote-based model tied to case complexity and practice area, with no publicly disclosed pricing. No revenue figures, funding rounds, or external investment are reported, and the firm is entirely owned and managed by its partners. The firm has been recognized by Global Law Experts as Labour Law Firm of the Year in 2023 and 2025 and Commercial Litigation Law Firm of the Year in 2025. In 2026, Vera Lúcia Santos and David Pereira were promoted to Partner, signaling the next phase of succession and capacity expansion.

Scale indicators3 records

Recent moves8 records

Expansion highlights5 records

Direct peers

• Uría Menéndez: Iberian law firm with strong Portuguese practice (having merged with Portuguese firm in recent years). Directly competes for corporate, M&A, labour, and litigation mandates involving Portuguese or cross-border Iberian work, and operates through international networks similar to DNM's AEA/Justinian memberships.
• BMA – Baptista, Monteverde & Associados: Independent mid-sized Portuguese law firm with a similar profile of full-service offerings for corporate and individual clients. Directly comparable in size and practice scope to DNM, including cross-border work through international networks.

Broad incumbents

• Vieira de Almeida (VdA): Top-tier Portuguese full-service firm with deep corporate, labour, tax, and dispute resolution practices. Competes for the same corporate-client mandates as DNM in Portugal, particularly those with foreign-investment or multi-jurisdictional dimensions.
• SRS Advogados: Portuguese full-service firm with offices in Lisbon, Porto, and Faro. Overlaps with DNM's corporate, real estate, labour, and public-sector practices, particularly relevant for SME and regional corporate clients in Portugal.
• DLA Piper: Global law firm with a substantive Lisbon office. Competes for the same large corporate, M&A, and cross-border mandates that DNM accesses through AEA/Justinian indirectly, and represents the international-firm benchmark for many of DNM's target clients.
• PLMJ Advogados: One of Portugal's largest full-service law firms with offices in Lisbon, Porto, and international outposts. Comparable as a Portuguese full-service firm offering corporate, labour, litigation, tax, IP and public-procurement services, but at materially greater scale and geographic footprint than DNM.
• Cuatrecasas: Major Iberian law firm with a substantial Lisbon office. Comparable across many of DNM's practice areas (corporate, labour, tax, litigation, public law) but with vastly greater headcount and international coverage.
• Pérez-Llorca: Spanish full-service firm with strong corporate, M&A, and dispute resolution practices. Comparable to DNM's full-service positioning and Iberian cross-border referral flow, although operating primarily out of Madrid.
• Morais Leitão, Galvão Teles, Soares da Silva & Associados: Leading Portuguese law firm with a full-service offering covering corporate, finance, litigation, public law, IP and labour. Comparable practice breadth to DNM but at significantly larger scale and with established international network memberships.

Regional players

• Gómez-Acebo & Pombo: Major Spanish law firm with corporate, labour, litigation, tax and IP practices. Shares the broad Spanish/Portuguese legal-market adjacency and overlapping client base for cross-border Iberian mandates, though headquartered in Madrid rather than Lisbon.
