I went through a very similar "incident". If you do have the Cert. of Origin you can give that to the purchaser and he will be able to register that vehicle in any state. In NJ, when you register an ATV, trailer, etc... you will only have the registration card to pass along to the buyer. NJDMV does not issue a new title for ATV's, trailers, etc.... The registration card acts as your proof of ownership, just went through this with a quad i just sold. hope this helps you out.
