1. Within 15 days after the time for filing claims has expired, as provided in this chapter, the personal representative shall examine all claims filed and shall either endorse on each claim an allowance or rejection, with the day and the year thereof, or shall file a notice of allowance or rejection with the date and the year thereof, and the notice of allowance or rejection must be attached to the claim allowed or rejected and filed with the clerk.
2. If a personal representative refuses or neglects to endorse on a claim an allowance or rejection within 15 days, as specified in this section, or does not file a notice of allowance or rejection, the claim shall be deemed rejected, but the personal representative may, nevertheless, allow the claim at any time before the filing of the final account.
3. A personal representative need not allow or reject a claim that was not timely filed unless the court otherwise orders.
