Question for Istoryans who experienced the same situation or those who have actual knowledge.

I lost my original Certificate of Registration (CR) due to fire and now I'm planning to sell my car.
Do I still have to request for duplicate CR in LTO prior selling my car? Or can I support my photocopy of CR and OR with deed of sale as I will be applying for transfer of ownership to the new owner.

I noticed that it will be redundant and time consuming if I will first apply for duplicate CR then later on apply for transfer of ownership. Also, it will be costly as I'll be paying more.

Just want to know if I could have it as one transaction the transfer of ownership and not going anymore for duplicate CR request. Except if original CR is really required then I really need to apply for duplicate CR prior transfer of ownership.

Hope someone could give a reliable feedback.
