16 Pa. Stat. § 7563
All premiums charged or chargeable by any surety company for becoming or remaining as surety on such bond for any period after the last day of December, one thousand nine hundred and thirty-eight, or the proportionate part of any annual premium covering the period during which any sheriff or coroner remains in office after said date, shall be paid out of the treasury of the proper county on warrants drawn by the sheriff or coroner or the commissioners thereof, as existing laws may require for the payment of other expenses of the office of such sheriff or coroner, it being intended that this section shall apply to all premiums due or accruing on official bonds of sheriffs and coroners now in office for the year one thousand nine hundred and thirty-nine, as well as for subsequent years of their terms or of the terms of their successors. If any such premium or part thereof has been paid by any sheriff or coroner, because of any claim by the surety or other county officers that he was personally liable for same, the county shall reimburse him for such expenditure in manner aforesaid upon satisfactory proof of such payment.
