"Family and gift transfers.
The following applies to vehicles which are currently registered in California:
If you acquire a vehicle from your spouse, sibling, child, parent, grandparent, grandchild, or as a gift, you must record this transfer of ownership within 10 days from the date you take possession.
You will need the title, also known as the pink slip, with the previous owner's releasing signature on line one. If the title shows a legal owner, their release must appear on line two.
If the title is lost, an Application for Duplicate Title (REG 227) must be completed and signed. When an application for duplicate title is used, the legal owner's signature must be notarized.
An odometer mileage certification is required if the vehicle is less than 10 years old. If the title does not have a designated space for this information, a Vehicle/ Vessel Transfer and Reassignment Form (REG 262) signed by both the seller and the buyer will be required. The REG 262 cannot be copied. An original must be submitted. To obtain a form by mail, call DMV's automated phone service 24 hours a day, 7 days a week at 1-800-777-0133. To speak to an operator, call between the hours of 8 a.m. and 5 p.m. Monday - Friday, Pacific Standard Time, or pick one up from your local DMV. If calling from outside the United States, please call 916-229-0370.
You must also complete a Statement of Use Tax Exemption (REG 256), to receive the exclusion from the smog certification and use tax."
Notice that if a duplicate title is used the signature must be notarized?
