In counties of the first class, the register of wills, before entering upon the duties of his office, shall, with one corporate surety or two individual sureties, on a form prepared and supplied by the Secretary of the Commonwealth, give a joint and several bond to the Commonwealth of Pennsylvania in the sum of forty thousand dollars ($40,000).
The condition of the bond shall be, that the said register of wills shall faithfully execute the duties of his said office and well and truly account for and pay according to law all moneys received by him for the use of the Commonwealth, and to deliver up the books, seals, records and other writings belonging to his said office, whole, safe and undefaced, to his successor in office. Such bond shall be for the relief of all who may be aggrieved by the acts or neglect of such register.
Such bond shall be submitted to the Secretary of the Commonwealth for approval, and when approved, the Secretary shall forward the bond, together with the commission of the register, to the recorder of deeds of the county, and so notify the register, who shall cause such bond to be recorded in the office of the recorder of deeds. After recording such bond, the recorder of deeds shall deliver to the register his commission, and forward such bond to the Secretary of the Commonwealth for filing.
