Documents and plates when you sell

Most of the stress in a Swiss car sale is paperwork, and almost all of it is predictable. Two rules carry the whole thing: the registration document belongs to the car, and the plates belong to you.

What the buyer receives

The vehicle registration document goes to the buyer at handover, because they cannot register the car in their own name without it. Hand over both keys, the service booklet with its invoices, the latest inspection report if the car has one, and the manuals.

Anything you keep, such as a second set of wheels or an accessory, belongs in the contract so nobody remembers it differently later.

What you keep

The plates stay with you. Take them off before the buyer drives away, and either move them to your next car or return them to your cantonal road traffic office.

Keep a signed copy of the sale contract and a photo of the mileage at handover. That is your evidence if anything is questioned afterwards.

Stop the running costs

Vehicle tax and insurance keep running until the registration is closed, so deal with the plates promptly rather than in the following weeks. Once the registration is closed, ask your insurer for the unused premium and your canton for the unused tax back.

If the car is leased or financed, contact the lender before you advertise it. The outstanding amount has to be settled through them and that changes the timing of the sale.

Frequently asked questions

Who keeps the licence plates when a car is sold in Switzerland?

The seller. Plates are issued to the owner, not the vehicle, so you remove them at handover and either transfer them to another car or return them to your canton.

Do I have to deregister the car myself?

You close your own registration by returning or transferring the plates. Registering the car in their name is the buyer's responsibility, using the vehicle registration document you hand over.

Can I get insurance and vehicle tax back?

Yes, normally the unused part. Once the registration is closed, your insurer refunds the remaining premium and your canton refunds the remaining tax for the year.

Can I sell a car that is still on a lease?

Not directly. Speak to the leasing company first, because the outstanding balance has to be settled through them before ownership can pass to a buyer.
