Who is responsible for getting the road worthy certificate when buying a used vehicle?

When buying a used vehicle, the responsibility for obtaining a roadworthy certificate typically falls on the seller, as it is often required for the sale to ensure the vehicle meets safety standards. However, buyers can negotiate this aspect, and in some cases, they may choose to obtain the certificate themselves to ensure the vehicle's condition meets their expectations. It's important for both parties to clarify this responsibility during the sale process.
