Belgium has three official languages (Dutch, French, German). The contract must be understood by both parties, but the most common versions are in (for Flanders) and French (for Wallonia and Brussels). This guide covers the essentials regardless of language. 1. Is a Written Contract Mandatory? Yes, for most private sales. Since 2018, Belgium requires a written contract for the sale of a registered vehicle between private individuals. If you buy/sell without one, the registration office (DIV) will reject the transfer.

“Le vendeur déclare que le véhicule est vendu sans garantie contre les vices cachés, sauf ceux que l’acheteur a pu constater lors de l’essai. Le vendeur exclut la garantie légale des vices cachés.” If you want, I can also provide a full fillable template in English with Dutch/French translations. Just let me know.
