How do I register a used car I bought from a private seller?

Updated October 2026 · How we answer

Short answerYou'll need the signed title, bill of sale, proof of insurance, and payment for fees and taxes. Visit your local DMV, submit the paperwork, and get your plates and registration.

Paperwork you'll need

To register a used car bought from a private seller, you typically need the signed-over title, a bill of sale (some states require it), proof of insurance, and your driver's license. If there's a lien, you'll need the lien release.

Some states require a odometer disclosure statement, a damage disclosure, or a smog certificate (like California). Check your state DMV website for the exact list.

If the seller didn't sign the title correctly, you'll need to contact them to fix it—this can delay registration.

  • Signed title (with seller's signature).
  • Bill of sale (if required).
  • Proof of insurance.
  • Driver's license or ID.
  • Lien release (if applicable).
  • Smog certificate (in some states).

Steps to register

First, make sure you have insurance on the car. Then, go to your local DMV office (some states allow online or mail-in registration). Bring all paperwork and payment for fees and taxes.

The DMV will process the title transfer, collect sales tax (if applicable), and issue you new license plates and a registration card. You may receive the new title in the mail later.

Fees vary by state and vehicle value—typically $50 to $200 for registration and title, plus taxes. If you bought the car out of state, you may need a VIN inspection.

  • Get insurance first.
  • Visit DMV with all documents.
  • Pay fees and taxes.
  • Receive plates and registration.
  • New title may arrive by mail.

Common mistakes

  • Forgetting to get a bill of sale when required, which can delay registration.
  • Not checking for a lien on the title—if one exists, you can't register until it's released.
  • Missing the deadline to register and transfer the title, leading to penalties.
