(a) The defendant may apply by noticed motion to the court in which the action is pending or in which the judgment in the action was entered for an order releasing the attachment of property to the extent that the value of the defendant's interest in the property clearly exceeds the amount necessary to satisfy the amount to be secured by the attachment.

(c) At the hearing on the motion, the court shall determine the value of the defendant's interest in the property and order the release of the attachment of the property to the extent that the value of the defendant's interest in the property attached clearly exceeds the amount necessary to satisfy the amount to be secured by the attachment. After entry of judgment in the action in which the property was attached, the court shall also take into consideration in determining whether the attachment is clearly excessive the value of any property not attached in the action that (1) has been levied upon pursuant to a writ of execution issued to satisfy the judgment in the action or (2) otherwise has been sought to be applied to the satisfaction of the judgment in the action.
