California: Private-Party Vehicle Title Transfer Requirements
The short answer
The seller and buyer complete and sign the California title, and any recorded lienholder must release its interest; the buyer then submits the endorsed title, transfer fee, use tax, and any required smog and odometer documents to DMV within 10 days. An ordinary current-title transfer does not require notarization, and a bill of sale is generally supplemental, although DMV requires one to bridge the ownership chain when the seller is not the person named on the title. The seller must file a Notice of Transfer and Release of Liability within five calendar days; that notice can shift later liability but does not itself transfer ownership.

This is the general rule in California. Ezel applies current California law to your specific facts and answers with citations to the statutes.
| Governing law, agency, and scope | Cal. Veh. Code §§ 5600, 5602, 5750-5753, 5900, and 5902; California DMV. Ordinary private sale of a currently titled California passenger vehicle. |
|---|---|
| Title assignment, owner signatures, and lien release | Seller and buyer sign/address the title; 'and'/slash or JTRS co-owners all sign, while 'or'/'and-or' needs one releasing owner. A recorded lienholder signs the title or gives an accepted release, and on payoff must release and deliver the title within 15 business days or owe the buyer $25/day up to $2,500 (§ 5753(c),(e)); very recent titles may require a lienholder-requested replacement title (DMV basic-transfer rules; §§ 5750-5753). |
| Notarization, witness, or agent verification | No notary, witness, or agent verification for the ordinary current-title assignment. If the title is lost/damaged and REG 227 is used, the lienholder signature must be notarized when applicable (§ 5752; DMV title-transfer FAQ). |
| Bill of sale requirement and contents | Not required when the titled owner directly signs and delivers the current title. Required if the seller is not the owner named on the title, signed by both that seller and the titled owner; optional REG 135 records seller/buyer, VIN, year/make, plate, sale date, and price (DMV private-sale instructions). |
| Odometer, damage, and title-brand disclosures | Odometer disclosure uses the complying title or secure REG 262, with original seller and buyer signatures and no POA, under DMV's current 20-model-year rule. No separate ordinary damage-disclosure form appears in the basic-transfer checklist; salvage/rebuilt-title procedure is outside scope. |
| Seller notice, plate handling, and liability | Seller files the Notice of Transfer and Release of Liability (online or REG 138) within 5 calendar days and keeps confirmation (§ 5900). A complete NRL shifts specified later liability but does not transfer ownership or remove the seller's name; standard-plate removal is not an ordinary checklist step (§ 5602; DMV NRL page). |
| Buyer deadline, forms, tax, and fees | Within 10 days after receiving the endorsed title, buyer sends or delivers it to DMV with transfer fee and applies for transfer (§ 5902). Basic filing also includes buyer ID information, purchase date/price, use tax or exemption, lien information, odometer disclosure, and smog certification/exemption. |
| Inspection, emissions, insurance, and operation | Seller generally provides a valid smog certification; transfer exemptions include a vehicle under 4 model years old, for which buyer pays the transfer fee identified by DMV. California has no ordinary safety-inspection step, but owner/driver must carry evidence of financial responsibility to operate (§ 16020). |
| Penalties, rejection, and failed transfer | Transfer is not effective until the statutory title-and-filing path is completed (§ 5600); failure to endorse, date, and deliver the title is unlawful (§ 5753(a)). Registration fees are due within 20 days of transfer (§ 9553(b)); after that a graduated penalty runs from $10 (10 days or less) to $100 (over two years) plus a vehicle-license-fee percentage penalty (§ 9554(b)-(c)), and delinquency can lead to impoundment (§ 9553(e)). An incomplete lien release, signature, odometer statement, smog item, tax, or fee can stop issuance; the seller's NRL limits exposure but does not cure buyer nonfiling. |

Requirements one by one
The title and DMV filing work together
Vehicle Code § 5600(a)(1) says an attempted transfer is not effective until the
seller properly endorses and delivers the title and the buyer sends or delivers
it to DMV with the transfer fee and use tax, or the seller follows the
statutory document-submission alternative. A bill of sale and delivery of the
car are not substitutes for that title-and-filing path.
Vehicle Code § 5750 and § 5751 require the transferor and transferee to sign the title
and require the transferee's address. DMV adds the practical co-owner rule:
every owner joined by "and," a slash, or JTRS signs; one owner may release when
the names are joined by "or" or "and/or." A recorded lienholder must release
its interest on the title or through an accepted release. When a loan is paid
off, § 5753(c) gives the legal owner 15 business days after full payment and a
signed release authorization to release its interest and deliver the title;
missing that window costs the legal owner $25 per day, up to $2,500 (§ 5753(e)).
Vehicle Code § 5753(a) separately makes it unlawful to fail to endorse, date,
and deliver the title to a transferee entitled to the transfer.
Ordinary current-title signatures are not notarized
California does not require a notary or witness for the ordinary transfer of a
current California title. The notarization rule in § 5752 belongs to the
different lost, stolen, damaged, or mutilated-title route: when REG 227 replaces
the title, an applicable lienholder signature is notarized.
A bill of sale is likewise not the ordinary transfer instrument. DMV requires
one when the private seller is not the person named on the title, signed by both
that seller and the titled owner. REG 135 is available as a transaction record,
but the buyer still needs the assigned title and DMV filing.
Odometer and smog documents can block the application
Vehicle Code § 5600(b) allows DMV to require a secure odometer form. DMV's current
specialized rule applies a 20-model-year disclosure period to post-2021
transfers and requires original seller and buyer signatures; a power of
attorney cannot sign the mileage disclosure. Use the title's complying
odometer section or secure REG 262 as DMV directs.
For smog, the seller generally gives the buyer a valid certification. DMV says
a car under four model years old uses a smog transfer fee instead of a new
inspection. Vehicle Code § 5751.5(a)-(b) also addresses the narrower case where a still-valid
prior certification makes another test unnecessary and requires a signed
emissions-system statement.
Seller and buyer have different clocks
The seller's deadline is five calendar days under § 5900(a). File the Notice of
Transfer and Release of Liability online or on REG 138 and keep the
confirmation. Section 5602 and DMV's NRL page describe the liability protection,
but DMV is explicit that the NRL does not transfer ownership or remove the
seller's name from the record.
The buyer's deadline is 10 days after receiving the properly endorsed title.
Section 5902 requires the buyer to send the title and transfer fee to DMV and
apply for the transfer. The application must also clear the lien-release,
identity, price/date, tax, odometer, and smog items that apply.
Insurance is an operating rule, not a substitute for transfer
Proof of insurance is not listed as the ordinary title document in DMV's basic
transfer checklist. But § 16020(a) separately requires every driver and owner to
be able to establish financial responsibility and carry evidence in the
vehicle. A signed title does not authorize driving an unregistered or uninsured
car.
Late filing carries graduated penalties
Once the vehicle is transferred, § 9553(b) gives the buyer 20 days to pay the
registration fees that come due "without payment of penalties." After that,
§ 9554(b) adds a registration-fee penalty that climbs with delay — "Ten dollars
($10) for a delinquency period of 10 days or less," rising to "One hundred
dollars ($100)" after two years — on top of a percentage penalty on the vehicle
license fee (§ 9554(c)); continued delinquency can lead to impoundment
(§ 9553(e)). Because § 5600 makes a transfer ineffective until the
title-and-filing path is complete, a missing signature, lien release, smog
certificate, tax, or fee can also stop the application.
What trips people up
- Treating the NRL as the transfer. It can protect the seller from later
parking, abandonment, operation, and related exposure, but only the buyer's
completed transfer changes the vehicle record. - Using the older 10-year odometer shorthand. DMV's specialized current
disclosure page uses a 20-model-year rule for post-2021 transfers. Check its
current-year table and use original signatures on the title or REG 262. - Buying from someone not named on the title. DMV requires a bill of sale
signed by both the seller and the titled owner. A one-signature receipt does
not repair the chain of ownership. - Leaving smog until after payment. Unless an exemption or still-valid
certificate applies, the seller must provide the smog certification needed
for transfer.
Common questions
Does a California bill of sale transfer the car by itself?
No. Section 5600 ties an effective transfer to the endorsed title and DMV
filing. The bill of sale is supporting evidence and is specifically required
when the seller is not the owner named on the title.
Do the seller's and buyer's title signatures need notarization?
Not for the ordinary current-title transaction. The notary issue arises in the
lost or damaged-title route when an applicable lienholder signs REG 227.
Who files first?
Do both promptly. The seller files the NRL within five calendar days (§ 5900);
the buyer applies with the endorsed title within 10 days (§ 5902).
Who is responsible for the smog certificate?
DMV says the seller gives the buyer a valid certification unless an exemption
applies. For a vehicle under four model years old, the buyer pays the smog
transfer fee instead of obtaining a new inspection.
