Regarding second hand bike paper transfer

Dear Sir,
You may inform RTO Authorities and Police accordingly. You may say that the vehicle is in illegal custody of the purchaser.

Dear Client,
It is important to follow the mandatory requirements under the Motor Vehicles Act, 1988 for the transfer of ownership of the vehicle. Accordingly, the Seller and the Buyer must sign statutory forms and change of address in the Certificate of Registration(RC) to process the transfer of ownership of the vehicle. In the absence of such documents, you might face serious consequences. You can approach the RTO officer, inform him about your grievance and request him to take necessary action against the dealer. Further, you can send a legal notice to the dealer and escalate the matter to consumer court for deficiency in service and unfair trade practices. If required, you can consult an advocate for advice and assistance in the matter.
Hope it helps.
Thank you.

Dear Client,
There are statutory forms to be signed both by the ex-owner(Seller) and the present owner(Buyer) to process the transfer of ownership of the vehicle and change of address in the Certificate of Registration(RC). As per the mandatory provisions of the Motor Vehicles Act, 1988 and M V Rules, 1989, once a vehicle is sold, the purchaser has to submit statutory forms(Form 29. Form 30) and other required documents along with transfer fees within 30 days to the concerned RTO/Registering Authority for processing the transfer of ownership of the vehicle and change of address in the Certificate of Registration (RC) failing which the applicant Buyer has to pay fine or penalty for delay in submission of application for transfer of ownership(TO) and change of address(CA). Post-sale if the Buyer/New owner uses the running vehicle without transferring ownership of the vehicle and in case the vehicle meets with an accident, theft, or any other violation of the MV Act, both you and the existing owner of the vehicle as per the MV record, may face the legal consequences arising out to that accident or violation. The status of any vehicle is now readily available online and once you obtain the details of the vehicle and the existing owner, you can serve a legal notice to both the owner and second-hand car seller asking them to get the registration of the vehicle at the earliest. So, to protect your interest and safety and to avoid all sorts of unwanted consequences, you need to write to the concerned RTO ASAP informing the ordeals you are facing now and requesting them to take necessary action against the existing owner of the vehicle so that vehicle is registered in the name of present owner. you should visit the office of the concerned RTO frequently to speed up the process of registration of the vehicle. Reach out to an authorized MV Vendor or a Layers clerk who handles M V matters to resolve the issue in the right way.
