How do I sign my Colorado vehicle title?

Transferring vehicle ownership in Colorado requires a few specific steps to keep the sale legal and clean. If you are selling to a dealer, check with them first before signing anything on the title.

1. Verify Your Title

Check that the title is currently in your name and that all printed details are accurate. If you can't locate the title, or it's been damaged, you'll need to apply for a duplicate through your local Colorado DMV office before continuing with the sale.

2. Notarization Is Not Required

In a standard private sale, Colorado does not require notarization of the seller's signature on the title. Both parties simply need to sign the title itself. Notarization is generally only needed in unusual cases, such as when a representative is signing under a Power of Attorney — contact the Colorado DMV if you're uncertain.

3. Complete the Seller Information on the Back of the Title

Flip the title over to find the seller information section, which needs to be filled out without errors:

     
  • Seller's Signature: Sign in the box labeled for the seller's signature. All owners listed on the title must sign.
  • Printed Name of Seller: Print your name exactly as it appears on the title.
  • Buyer Information: Provide the buyer's full name and address in the designated section.
  • Odometer Reading: Provide the vehicle's accurate mileage at the time of sale, ensuring this information is filled in correctly without errors. It is important to not guess this number, and record an exact mileage number.

Important: Don't use white-out, cross-outs, or any other corrections on the title — even small edits can void the title.

4. Address Liens

Got a lien on the title? You'll need the lienholder's permission before transferring ownership. They can either sign the title directly or issue a lien release letter. The transfer isn't legal until the lien is officially cleared.

5. Consider Multiple Owners

If there are multiple names listed on the title, all parties must sign, depending on how the names are joined:

     
  • "AND": Both owners are required to sign.
  • "OR": Only one owner needs to sign.

Key Takeaways

     
  • Notarization is not required for a standard private sale.
  • Ensure all signatures match exactly as they appear on the title.
  • Address any existing liens before proceeding.

Sticking to this process keeps your Colorado sale legal and prevents costly title rejections. For more information, see the Colorado DMV title page.
