General information, not legal or tax advice
This page is general information about a commonly-used document. State and local law varies — for advice on your specific situation, consult a licensed attorney in your jurisdiction. AttachKit fills the PDF; you're responsible for whether the contents are right for your case.
- Does a California bill of sale need to be notarized?
- No. The California DMV states a bill of sale is not required to be notarized or witnessed. AttachKit does not provide notarization — it only helps you fill the form.
- Is REG 135 mandatory to sell a car in California?
- Using REG 135 is not mandatory; the signed Certificate of Title plus the transfer fee is what actually transfers ownership. Many sellers still complete a bill of sale as a record of the price and transaction.
- Does AttachKit submit the form to the DMV?
- No. AttachKit only helps you fill and download the official form. You are responsible for filing it with the DMV or keeping it for your records. This is not legal advice.
- Where does my data go?
- Nowhere. The PDF is filled entirely in your browser and is never sent to a server.
