As the seller, you have to provide the smog inspection certificate. Under California law, the seller of a vehicle is required to provide the buyer with a valid smog inspection certification at the time of the sale or transfer. Section 24007 (b)(2) of the California Vehicle Code provides that it is the responsibility of the seller to provide a valid smog certificate at the time of delivery of the vehicle.
The inspection is not required on a transfer if a biennial smog certification was submitted to DMV within 90 days prior to the vehicle transfer date (a vehicle inspection report may be required for proof of certification). The only other exception is a transfer of the vehicle to a family member (a spouse, domestic partner, sibling, child, parent, grandparent, or grandchild).
An "as is" sale is often misunderstood. "As is" only refers to the seller's warranties. It does not relieve a seller from fraudulent misrepresentation or concealment. Nor does an "as is" sale relieve the seller of other legal obligations such as smog.
