Real estate deeds that transfer property in Idaho can be recorded to provide constructive notice of the transfer. In most cases deed documents are recorded in the county where the property is located.
State statute in Idaho requires that witnesses to real estate deeds for property transfers have valid proof of the grantor's identity. Standard proof of identity would include a state or federal government issued identification. This statute also requires that the witness acknowledges that the grantor actually executed the document.
Idaho state statute 55-720 is as follows:
PROOF OF IDENTITY OF GRANTOR. The subscribing witness must prove that the person whose name is subscribed to the instrument as a party is the person described in it, and that such person executed it, and that the witness subscribed his name thereto as a witness.
