Just bought a used car, have the pink slip but no registration. Will this be a problem?

Neely Youngblut: Car's from before 1975, so need for smog check.I live in California.

Hope Lundmark: ive bought & sold hundreds of cars and rarely, if ever, had the registration.

Shaun Rapkowicz: if you want to sell the car, or have fanancial problems with the buyer/ and or the law.

Felicitas Phildor: no the owner kept the registration because on the back when you sell a car you take the registration and fill it out with all the buyers information, and mail it to the dmv. What happens when you go in, the dmv register the car in your name, and gives you a temporary registration to prove you now own the car. You will need proof of insurance, and may need a smog certificate depending on what state you live in. So register and enjoy your new to you new car!!
