Bill of Sale Requirements in ID

If the existing title has an area where the seller can declare the amount you paid for the vehicle (as most blue Idaho titles do), you will not need to fill out a separate bill of sale.

However, if the title does not provide space to declare the selling price, the seller must complete and sign a Bill of Sale (Form ITD 3738), naming the buyer as the vehicle's new owner. This is a state requirement as it:

  • Records the exact sale price.
  • Provides information on both the buyer and seller.
  • Serves as a document necessary in the state's titling process.

NOTE: The transfer of ownership of a vehicle requires reassignment of the vehicle title. Visit our Title Transfer in Idaho page for more information.
