Belgium's Prince Laurent Legally Recognizes His Son — But a Royal Title Isn't Automatic
Clément Vandenkerckhove was legally recognized as the son of Prince Laurent of Belgium through a formal registration at the civil registry in 2026 (VRT NWS). This civil recognition gives Vandenkerckhove equal inheritance rights to Prince Laurent's private estate (The Telegraph). Prince Laurent had publicly confirmed paternity of the 25-year-old on September 9, 2025 (E! News).
While Vandenkerckhove can now claim the title of Prince of Belgium, the designation is not automatic (Eventail). For him to officially bear the princely title, King Philippe and the Belgian government must still sign a royal decree — known in French as an arrêté royal — which is a formal executive order issued by the monarch and a government minister (VRT NWS). Vandenkerckhove cannot succeed to the throne (Eventail).
The broader context here involves the legal framework governing Belgium's royal household and the distinction between three separate things: civil paternity (legal fatherhood), dynastic titles (official royal designations), and succession rights (the right to inherit the throne). Civil recognition establishes legal filation — the formal parent-child relationship recognized by law — and its associated private-law consequences, such as inheritance. Dynastic titles, however, remain within the authority of the sovereign and the executive branch, requiring separate state action. The bar on succession reflects the constitutional framework governing the Belgian monarchy.
The case invites comparison to the 2020 legal proceedings involving another member of the Belgian royal family. In October 2020, the Belgian Court of Appeals granted Delphine Boël and her two children princely titles (BBC News). Boël, born out of wedlock to former King Albert II, was awarded the title Princess of Belgium and the right to be addressed as Her Royal Highness. The court ruling also permitted Boël and her children to adopt the surname of her biological father, Saxe-Cobourg (BBC News).
The Boël and Vandenkerckhove cases proceed through different legal mechanisms but ultimately address the same intersection of private family law and public dynastic identity. Boël secured her titles and surname through a judicial ruling by the Court of Appeals. Vandenkerckhove's path relies on voluntary civil recognition by the father, followed by the potential conferral of a princely title through the executive royal decree process.
In my view, the requirement for a royal decree in the Vandenkerckhove case functions as a political and institutional checkpoint. King Philippe and the government hold the authority to determine whether the civil recognition translates into an official dynastic designation. This separation between the civil registry and the royal decree preserves executive and sovereign discretion over the composition of the royal house, even when legal filation is settled.
