A corporation must not be accepted or approved as surety on a bond or undertaking unless the following conditions are met:
An officer of the court or member of the State Bar may not act as a surety.
An original bond or undertaking may be withdrawn from the files and delivered to the party by whom it was filed on order of the court only if all parties interested in the obligation so stipulate, or upon a showing that the purpose for which it was filed has been abandoned without any liability having been incurred.
