Got my daughter's car titled over to us, and got it registered in the State of Colorado. What an ordeal! We needed: Title, VIN verification, emissions inspection, and proof of insurance. And some money too.
The car was licensed and registered in Washington state, where my daughter used to live in 2019. The title to the car was up in Ft. Collins (northern Colorado) at my daughter's husband's family's house. The car itself was here with me in central Colorado.
My insurance company didn't want to insure the car on our policy, because we didn't own it. But in order for us to own it, we needed proof of insurance. Catch-22. But the insurance finally added it to our policy after a conference call with my daughter in Hawaii on the line. Check.
We got the title mailed to us. It wasn't signed appropriately, but that was a simple matter to rectify at the Department of Motor Vehicles (below). They let me sign it myself without the seller signature. Check.
Took the car over to the emissions inspection place and got it certified as clean. They didn't inspect anything except for the gas cap seal. They also plugged a cable into some place under the dash (I assume to access the on-board computer). Evidently the computer told them that they car was not putting out any bad gasses. How trusting of them to believe that. But we got the clean air certification. Check.
Went to the police station to get a "VIN verification". They needed proof of ownership, but the title was sitting up at my house at the moment. They said the registration paperwork would be sufficient. I pointed out that the registration paperwork was from Washington state, was in my daughters name (until I could get the car registered in Colorado), and the current registration didn't mention my name or my address anywhere on it. So how does that give me "proof of ownership" of the vehicle? That's still a mystery to me, but the police said it was fine. They gave me my VIN verification.
Next stop was the Department of Motor Vehicles, lugging along 2-1/2lbs of paperwork at this point. This is where they pointed out that there was a missing signature in one spot on the title, but then they said I could sign it myself. I think after finding out I could sign a title over to myself, and the police will accept a registration with someone else's name on it, from out of state even, as proof of my ownership, I just might have to get into the car theft business. Seems rather trivial to put a car in your name without having to bother dealing with the pesky previous owner.
I complimented the lady at the Motor Vehicle place, regarding the thoroughness of the process, and was on my way with a new registration, a new title, and new license plates. It had taken me half the day, but that's actually better than I initially estimated.
