A V5C, also known as a vehicle registration document or logbook, is a paper document issued by the Driver and Vehicle Licensing Agency (DVLA) to the registered keeper of a vehicle. It contains all the essential information about the vehicle, such as the date it was first registered, its manufacturer, and the colour and engine size. It also shows who the vehicle’s registered keeper is. The registered keeper is the person responsible for registering and taxing the vehicle, not necessarily the person with a legal claim to ownership. The V5C is an important document when buying or selling a car, as it proves that you are the registered keeper of the vehicle. It is also important to check the V5C when buying a car to ensure that it is genuine and that the details of the vehicle match the one you are buying. If you lose or damage your V5C, you can apply for a replacement online or by filling out a V62 form and sending it to the DVLA.
