Code Civ. Proc., § 917.2

The perfecting of an appeal shall not stay enforcement of the judgment or order of the trial court if the judgment or order appealed from directs the assignment or delivery of personal property, including documents, whether by the appellant or another party to the action, or the sale of personal property upon the foreclosure of a mortgage, or other lien thereon, unless an undertaking in a sum and upon conditions fixed by the trial court, is given that the appellant or party ordered to assign or deliver the property will obey and satisfy the order of the reviewing court, and will not commit or suffer to be committed any damage to the property, and that if the judgment or order appealed from is affirmed, or the appeal is withdrawn or dismissed, the appellant shall pay the damage suffered to such property and the value of the use of such property for the period of the delay caused by the appeal. The appellant may cause the property to be placed in the custody of an officer designated by the court to abide the order of the reviewing court, and such fact shall be considered by the court in fixing the amount of the undertaking. If the judgment or order appealed from directs the sale of perishable property the trial court may order such property to be sold and the proceeds thereof to be deposited with the clerk of the trial court to abide the order of the reviewing court; such fact shall be considered by the court in fixing the amount of the undertaking.
