The following is required to register a nonresident vehicle: 

1. An Application for Title or Registration (REG 343) signed by all registered owners, showing the name and address of the lienholder (legal owner), if any.
   
2. Last issued out-of-state title, unless held by the lienholder/legal owner (This applies only if there is not a change of registered owner.)
   
3. Last issued registration certificate, if the applicant is the same as the registered owner shown on the out-of-state title and the vehicle entered California with valid out-of-state registration, or if the title has been lost.
   
4. Bill of Sale if the person from whom you are buying the vehicle purchased it from the registered owner shown on the title.
   
5. Odometer disclosure statement signed by the seller and buyer if the vehicle is less than ten model years old.
   
6. The vehicle must be inspected by an authorized DMV employee, law enforcement officer, or a licensed vehicle verifier. These inspections are most easily obtained by bringing the vehicle to the nearest DMV, where there is no extra fee charged for the inspection. For faster service, make an appointment.
   
7. Smog certification, if applicable.
   
8. Weight certificate, if applicable
   
9. Declaration of Gross Vehicle Weight/Combined Gross Vehicle Weight (REG 4008) 
   form for commercial motor vehicles (pickups with unladen weight of 8,000 lbs. or less are exempt from this requirement)
   
10. Appropriate Fees - Fees must be paid within 20 days of entry or residency to avoid penalties.
