The term "pink slip" is a name commonly given to the pink car titles issued by the state of California. The look of the titles has since been modified, but if you are buying or selling an older car in California you will need to sign your name on the car's pink slip in order to complete the transaction.
Make sure that everything is filled out on the pink slip correctly. Whether you are buying or selling the car you want to make sure that all the information on the pink slip is correct.
Sign your name in the top box on the front side of the pink slip if you are the car's title holder. Sign the bottom box if you are the car's lien holder. The boxes are stacked on top of one another and take up nearly the whole front part of the pink slip.
Sign the back side of the pink slip if you are the car's new owner or lien holder. If you are the car's new owner you will want to sign your name in the top box of the second section (the first box after the line break). If you are the car's new lien holder you will sign your name in the top box of the third section (the box second from the bottom).
