Idaho Code § 8-120: Deposit with sheriff.

The defendant, or a person on behalf of the defendant, may at the time of the defendant’s arrest, instead of giving bail, deposit with the sheriff the amount mentioned in the order. In case the amount of bail be reduced, as provided in this chapter, the defendant, or a person on behalf of the defendant, may deposit such amount instead of giving bail. In either case the sheriff must give the person who made the deposit on behalf of the defendant, a certificate of the deposit made, and the defendant must be discharged from custody.
