Selling car left from overseas

what are the documents and signatories needed in selling a car left in Riyadh KSA. i am now overseas and unable to go back to Riyadh because of medical reason. I want to sell my car to my friend in Riyadh.

Ask your friend to go to traffic dept. ( Moror) to know all the needed details regarding this case.

I think this is the easiest way to know what you are asking for

Thank you sir. I will do that.
