California Title Transfer Checklist: Everything You Need Step by Step

Quick Answer: California title transfers usually need a signed Certificate of Title (or REG 227 if the title is missing) and a REG 343 application. For most vehicles you also need a smog certificate, an odometer disclosure for eligible cars, and a bill of sale. You pay the $15 transfer fee plus use tax (7.25% statewide base, higher in counties with district taxes) and any registration fees. Buyers have 10 days after purchase to submit everything, and sellers have 5 days to file the NRL. The exact documents depend on your transfer type, so use the checklist below for your situation.

Find your scenario below and use the checklist that applies. If your situation spans more than one (e.g., inherited out-of-state vehicle), combine the relevant checklists.

Checklist A: Standard Private Party Sale (Most Common)

Seller must provide / complete:

  • ☐ Signed Certificate of Title -- signature on Line 1 (owner release) AND transferor/odometer section
  • ☐ Odometer disclosure -- recorded on title or REG 262 (model year 2011+ within 20 years; model year 2010 and older within 10 years)
  • ☐ Smog certificate -- valid within 90 days (most gas vehicles more than 4 model years old). Vehicles 4 model years old or newer are exempt but pay an $8 smog transfer fee, and qualifying family transfers are exempt from the smog inspection
  • ☐ Notice of Transfer and Release of Liability (NRL/REG 138) -- filed within 5 days of sale
  • ☐ Bill of sale (REG 135) -- not legally required but strongly recommended

Buyer must submit:

  • ☐ Signed title from seller
  • ☐ REG 343 (Application for Title or Registration) -- signed by all buyers
  • ☐ Smog certificate (from seller)
  • ☐ Proof of California insurance
  • ☐ Payment: $15 transfer fee + use tax (7.25% statewide base, higher with county district taxes) + registration fees if due
  • ☐ Submit within 10 days of purchase

Checklist B: Out-of-State Purchase

Additional or different requirements:

  • ☐ Out-of-state title (original) -- signed by seller; California will surrender this and issue a CA title
  • ☐ REG 343 signed by all buyers
  • ☐ REG 31 (VIN verification) -- completed by DMV employee, licensed verifier, or CHP
  • ☐ Smog certificate from a California-licensed station -- out-of-state certificates not accepted
  • ☐ Proof of California insurance
  • ☐ Payment: $15 transfer fee + use tax + base registration ($74) + CHP fee + VLF (0.65% of value) + county fees
  • ☐ Submit within 10 days of purchase (20 days if new CA resident establishing residency)

Checklist C: Inherited Vehicle (No Probate)

Requirements:

  • ☐ Wait 40 days from the date of death before submitting
  • ☐ REG 5 (Affidavit for Transfer Without Probate) -- signed by heir
  • ☐ Certified copy of death certificate
  • ☐ Certificate of Title or REG 227 if title is unavailable
  • ☐ Smog certificate if required and not exempt
  • ☐ Transfer fee: $15
  • ☐ Estate qualifies: the decedent's other California property must not exceed $208,850 (deaths on or after April 1, 2025). The vehicle itself is excluded from this calculation, so a car of any value can transfer as long as the rest of the estate stays under the cap

Checklist D: Lien Payoff (Removing Lienholder)

Paper title lenders:

  • ☐ Title signed by lienholder on Line 2 (releasing their interest)
  • ☐ OR: notarized REG 166 (Lien Satisfied/Title Holder Release), used in lieu of the lienholder signing the title. REG 166 is accepted only for vehicles older than two model years; for vehicles two model years old or newer the legal owner must obtain a duplicate title first (VC Section 5752)
  • ☐ Transfer fee: $15
  • ☐ Submit within 30 days of receiving the signed title

ELT lenders:

  • ☐ No action required from you -- DMV issues a clean title automatically after the lender transmits an electronic lien release

What NOT to Do: Common Rejection Causes

These will get your application rejected: Using white-out or correction fluid on the title voids the document. Crossing out information voids the document -- only one signature when two are required (owner line + transferor/odometer line). Submit an expired smog certificate (must be within 90 days). Missing odometer disclosure on eligible vehicles. Submitting a REG 343 that is unsigned or missing required fields. Forgetting to include the NRL if you are the seller.

Every item on this list is a reason the DMV mails an application back, and a rejection does not pause the 10-day clock, so the rework lands you in the late-penalty window. Xtreet pre-checks the whole package before it is submitted: the right checklist for your scenario, both required signatures, a current smog certificate, the odometer entry, and a complete REG 343. We then file it on your behalf and track it in your account, which is how you avoid the resubmission loop that turns a routine transfer into weeks of delay.

Late Penalties

Buyers who submit after the 10-day window:

  • Days 11-30: $30 late penalty
  • After 30 days: Penalties increase further. Registration renewal fees may also become due.

There is no grace period. The clock starts on the date of sale shown on the bill of sale or title.

Frequently Asked Questions

What documents do I need to transfer a car title in California?

The core documents are: the signed Certificate of Title, REG 343, proof of California insurance, and a smog certificate for most vehicles. Additional forms depend on the transfer type: out-of-state purchases require REG 31 (VIN verification), inherited vehicles require REG 5, and lien payoffs require the lien release.

What is the most common reason a title transfer is rejected by the California DMV?

Errors on the title itself, strikethroughs, white-out, or correction fluid, are the top cause. The second most common is missing the second signature (the transferor/odometer line). Third is an expired or missing smog certificate.

Can I transfer a title by mail in California?

Most title transfers can be sent by mail to the DMV Vehicle Registration Operations, PO Box 942869, Sacramento, CA 94269-0001. But out-of-state cars and some complex transfers need an in-person VIN check first, before you mail everything.

How much does a California title transfer cost?

The base transfer fee is $15. Use tax (7.25% statewide base, higher in counties with district taxes) is usually the largest single cost. Depending on the transfer type, registration fees, the VLF, a CHP fee, and county fees may also apply. See Understanding California DMV Title Transfer Fees for a full breakdown.

How long after submitting does it take to get the new title?

DMV processing takes 15-30 business days. The physical title is then mailed, arriving 2-6 weeks after processing completes. Total time from submission to title in hand is typically 6-10 weeks. See the full California Title Transfer Timeline for a stage-by-stage breakdown.
