Pennsylvania — quick answer
In Pennsylvania, a bill of sale is not required for a private vehicle sale and notarization is required. No witnesses are required. The relevant state form is MV-4ST. Ownership is transferred through the PennDOT via the assigned title.
Is a bill of sale required in Pennsylvania?
Not required. There is no standalone state bill of sale; the notarized title assignment and Form MV-4ST (completed through an authorized agent) govern the transfer.
Seller signs the title before a notary/agent; the transfer is processed through an authorized PennDOT agent (messenger/notary/tag service).
Does a Pennsylvania bill of sale need to be notarized?
Required. Pennsylvania is a title-notary state: the seller's signature on the title assignment must be notarized or completed before an authorized PennDOT agent.
Because Pennsylvania requires notarization, do not sign the title or bill of sale until you are in front of a notary. Both the document and a valid ID should be ready, and many banks and shipping stores offer notary services.
Witness requirements
No. Pennsylvania does not require witnesses for a standard private bill of sale.
Odometer disclosure
Federal law requires a written odometer disclosure when title is transferred for vehicles less than 20 years old. As of 2026 that means model year 2011 and newer; model year 2010 and older are generally exempt. Record the exact mileage — never round it. See the NHTSA rule.

Is a bill of sale proof of ownership?
Generally no. For titled property like a car or boat, the title is what proves ownership. A bill of sale proves that a sale happened and records the price, date, and terms — it supports the title transfer but does not replace it. For untitled property (furniture, equipment, electronics), the signed bill of sale is usually the main proof of ownership.
