Administrator surety bonds are generally required of firms recognized by courts or mediators to administer the estate of a deceased person, the affairs or guardianship of a minor or an incapacitated adult.  An administrator surety bond is a financial guarantee used by the court to ensure the property handling of the assets of an estate or truest.  The purpose of an administrator surety bond is to ensure that the administrator is financially capable to assume the fiduciary duties required by the court especially as they apply to the administration, management and disbursement of money in trust, the sale of real estate or business assets, and the necessary care of on-going service as required.
