Unless the parties otherwise agree, the hearing on an objection to an undertaking shall be held not less than 10 nor more than 15 days after service of the notice of motion. The court may order the amount of the undertaking decreased below the amount prescribed by Section 720.160 or 720.260 if the court determines the amount prescribed exceeds the probable recovery of the beneficiary if the beneficiary ultimately prevails in proceedings to enforce the liability on the undertaking.
