Three steps for REG 343
Use REG 343 Application for Title or Registration before filling, printing, or signing.
For REG 343, the key question is who is allowed to complete and sign each section.
A correct form can still fail if title evidence, lien release, inspection, or ID documents are missing.
Who fills it out
The applicant or owner completes the application with vehicle, owner, and transaction details.
Who signs it
The applicant/owner signs the certification; additional documents may need seller, lienholder, or verifier signatures.
Where it is submitted
Submit with the rest of the DMV title or registration packet.
Common mistakes
- Using REG 343 without ownership evidence.
- Forgetting REG 31 when required.
- Entering names that do not match the title or supporting documents.
If REG 343 is rejected
Get the reject reason precise enough to fix the next version. Ask:
Was the problem the form version, a blank field, the wrong signer, a VIN/name mismatch, missing title evidence, missing lien release, or the odometer disclosure?
