Sir,

     Please visit the local rto office and give a detailed application to them, about the transfer.

     You can also complain to your local police station against him, how he fails to transfer the 

     vehicle in his name and he is responsible if any mishappening happened in the future.

Sir, 

Do you have any Affidavit from the buyer? which states that he has bought this car from you on that date?

Hi, it is advisable to file a complaint at police station, under section 420 IPC for cheating..The car is still in your name,and in case of any incident you will be held liable for the compensation 

Dear Client,

You should issue a legal notice to the buyer with a cc to Regional Transport authority and police station(where the buyer lives) to change the ownership of the vehicle.

Police station will seize the vehicle immediately as the buyer has not changed the ownership details in RTA Office.

Regional transport Authority is also empowered to seize the vehicle if police do not act.

If he is refusing to register the car on his name instead of regular reminders then you should lodge an FIR for theft of your car and give his name as suspect.

Because the car is still on your name he will be forced to claim the ownership by registration on his name. 

Since you have sold the car and have already received the sale consideration amount and also have given him all the papers, you may inform the concerned  RTO office about this by attaching the copies of the relevant papers obtained  after selling the vehicle and inform that you have sold the vehicle  on so and so date after which you are not liable for any incident with regard to this vehicle ever since the date of selling this vehicle to that party.

You do not have to bother about it after this because you have washed away your responsibility by informing concerned RTO office about this.

You do not have to contact the buyer once again on this except that you inform the concerned RTO about  this in writing and complete and throw your responsibility on the buyer which will be safest way instead of begging the buyer on this.
