Idaho Bill of Sale for a Car
A bill of sale may be required for a private car sale in Idaho, depending on the situation. A properly released title is the standard transfer document; ITD lists the Bill of Sale (ITD 3738) among titling forms and says a bill of sale may be used only when a properly released title cannot be obtained, which requires additional steps.
