If you purchase a vehicle in another EU country or become the owner of a vehicle in another EU country through a gift or inheritance, the second-hand vehicle must be registered in that country before you can transfer it.
In Belgium, you must first declare the vehicle for tax purposes and have it undergo a technical inspection. Subsequently, you need to arrange insurance and, if you intend to use the vehicle on the road, register it with the Vehicle Registration Service (DIV). Certain categories of vehicles may require additional administrative inspections after registration.
Individuals relocating abroad, and consequently no longer officially registered in a Belgian municipality, must return their Belgian license plate to the DIV within 15 days. This can be done either by mail or at various DIV offices.
The minimum age to register a vehicle in your name is 16 years. From that age, you can obtain a driver's license for a moped and register the moped in your own name.
