Section 1802. Effect of failure to present claim If any claim is not presented on or before the day fixed in the notice published pursuant to the preceding section or if no notice is so published, within 7 months from the date of issue of letters, the fiduciary shall not be chargeable for any assets or moneys that he may have paid in good faith in satisfaction of any lawful claims or of any legacies or distributions to the legatees or distributees of the decedent before such claim was presented

Such 7  month  period  shall
  begin  on the date letters were first issued to any fiduciary, including
  a temporary administrator or a preliminary executor, and  shall  not  be
  interrupted  by  any  subsequent  issue of letters, except that the time
  during which there is no fiduciary in office shall  not  be  counted  as
  part of such period.
