PEN §823: On taking the bail, the magistrate must certify that fact on the warrant, and deliver the warrant to the officer having charge of the defendant.

On taking the bail, the magistrate must certify that fact on the warrant, and deliver the warrant to the officer having charge of the defendant. The magistrate shall issue to defendant a receipt for the undertaking of bail. The officer must then discharge the defendant from arrest, and must, without delay, deliver the warrant to the clerk of the court at which the defendant is required to appear. If the undertaking of bail is in the form of a bond, the magistrate shall forward the bond to the court at which defendant is required to appear. If the undertaking is in the form of cash, the magistrate shall deposit the cash in the county treasury, notifying the county auditor thereof, and the county auditor shall, by warrant, transmit the amount of the undertaking to the court at which the defendant is required to appear. If authorized by the county auditor, the magistrate may deposit the money in a bank account pursuant to Section 68084 of the Government Code, and by check drawn on such bank account transmit the amount of the undertaking to the court at which the defendant is required to appear.
