So I got a boat that was registered in Ca. The seller had the CA pink slip and a current regi for the boat. The trailer is registered as AZ permanent. Seller wrote a bill of sale for the boat and the trailer. He used the CF# for boat and the license plate number for the trailer. I didn't think anything of it. Went to DMV. They had no problem registering the boat. But with only a plate # and bill of sale for trailer, they said they couldn't do it. Went back today hoping to hear different from a different DMV employee (don't laugh, it's worked like night and day before). They said no way, no how without a current copy of the trailer registration from AZ. I talked to the seller and he acts like it's no big deal. Says that it's in his sister's name who lives in AZ still, says he'll get a copy of it and give me a call when he gets it. I feel like I screwed up by not making sure to get a copy of the current AZ regi BEFORE buying it. I don't really want to leave it alone and drive around with a AZ plate on it and NO paperwork........ But,,, If he can't come up with the regi card, what are my options?
