We have just moved from Switzerland to France with our car and I think we can help you with the process. We have tried to correct the information on the Glocals website, but most information online is incorrect. You should not have to pay anything if you are leaving Switzerland and permanently moving to France unless you sell the vehicle within 1 year of the move.
The process is not difficult but time consuming. It will take 2-3 months and you must not cancel your Swiss insurance during that time. You can not get insurance in France until you have a French Carte Grise.
You must start with the Swiss Douane and inform them that you are leaving Switzerland and moving to France. They will ask for your Attestation of Departure which you need to get from the OCP, your Swiss Carte Grise and identification. They give you a form which is a copy of your Swiss Carte Grise, the original copy must be kept if you ever plan on moving back to Switzerland. This is the only involvement from the Swiss Douane.
There is a form detailing the data you need to supply to the French Douane but I will summarize.
Attestation de Departure. They will require the original copy which they will keep. Make copies for futurerequests. Your departure date should be within 2 weeks of the date you go to the Douane. Otherwise, you will need to come back.
Inventory of household contents, furniture, cars, etc and a declaration of honor stating that nothing of interest within 6 months of the departure date.
2 copies of the Swiss Carte Grise
Proof of residence in France (2 copies) Rental agreement, Attestation de Vente or Attestation de la Mairie.
2 copies of your Passports
They will give you the forms which you will need to take to the Mairie to start the French Carte Grise process. You should not need to supply a European Certificate of Conformity for the vehicle to the Douane, but I showed them the one in acquired and you will need to have it for the required Control Technique in France. You can order it online or go back to the dealership.
You will have three months once you move to France to acquire your Carte Grise and French tags. The Mairie will send in the documents for you. The Mairie will give you forms to fill out plus you will need to send in the following:
Attestation de domicile
Copies of Passports
Once all that is submitted and accepted you will receive the Carte Grise and plate number by mail. You can take the Carte Grise to your local Feu Vert or order your plates online. If you have survived all this the final step is pop riveting the tags to the chassis of your vehicle as required by law.
I hope this helps and I did not leave anything out. We went to the French Douane with our paperwork before leaving to be sure that we had everything we needed and were sure to make copies of everyting for our files.
