Vehicle paperwork is set state by state — whether a bill of sale is required, whether anything needs notarizing, and how long the buyer has to transfer title. Pick your state for the questions that matter and a direct link to the official agency.
Why we do not list each state's rules here. The summaries published across the web contradict each other on notarization and transfer deadlines, and vehicle law changes without much notice. Publishing a confident-sounding table that is wrong would be worse than publishing none. Each state page sends you to that state's official agency and tells you exactly what to ask.
A written odometer disclosure is required on transfer for most vehicles under 20 model years old under federal law (49 U.S.C. § 32705), and electronic signatures are valid under the ESIGN Act in every state. Our bill of sale handles both automatically.
