What Dekeyser & Associés does

Dekeyser & Associés is a Brussels-based boutique law firm (cabinet d'avocats) founded in 1992, specializing in tax law and estate planning. The firm serves a primary client base of high-net-worth individuals, families, and business owners in Belgium, with a secondary international segment focused on Franco-Belgian cross-border tax situations. Its practice is organized around eight core specialties: donation planning, succession/estate planning, life insurance structuring, tax law (droit fiscal), real estate law, international matters, shareholder advisory, and family governance.

The firm's service model is traditional professional services delivery—quote-based advisory engagements delivered through direct consultations at its Brussels office (Rue Henri Wafelaerts 36, Saint-Gilles) with options for remote/video meetings. It does not develop proprietary technology, software, or digital platforms; its intellectual capital resides in practitioner expertise accumulated over 30+ years, codified through 445+ published blog entries, regular Anthémis Editeur book publications, and an active conference circuit. The firm is led by managing partner Grégory Homans, appointed in 2022, and operates with a lean 9-employee headcount.

Revenue is generated through professional services billing (consultation fees and matter-based retainers) with no public pricing disclosed. The firm pursues a sales-led go-to-market strategy built on reputation, thought leadership publications, educational conferences, and professional network referrals rather than outbound marketing or partnerships. The business is independently owned as a partnership of lawyers with no external investment, parent company affiliation, or subsidiary structure indicated.
