Mississippi Code Title 91. Trusts and Estates § 91-7-145

(1) The executor or administrator shall make reasonably diligent efforts to identify persons having claims against the estate. Such executor or administrator shall mail a notice to persons so identified, at their last known address, informing them that a failure to have their claim probated and registered by the clerk of the court granting letters within ninety (90) days after the first publication of the notice to creditors will bar such claim as provided in Section 91-7-151.

(2) The executor or administrator shall file with the clerk of the court an affidavit stating that such executor or administrator has made reasonably diligent efforts to identify persons having claims against the estate and has given notice by mail as required in subsection (1) of this section to all persons so identified. Upon filing such affidavit, it shall be the duty of the executor or administrator to publish in some newspaper in the county a notice requiring all persons having claims against the estate to have the same probated and registered by the clerk of the court granting letters, which notice shall state the time when the letters were granted and that a failure to probate and register within ninety (90) days after the first publication of such notice will bar the claim. The notice shall be published for three (3) consecutive weeks, and proof of publication shall be filed with the clerk. If a paper be not published in the county, notice by posting at the courthouse door and three (3) other places of public resort in the county shall suffice, and the affidavit of such posting filed shall be evidence thereof in any controversy in which the fact of such posting shall be brought into question.

(3) The filing of proof of publication as provided in this section shall not be necessary to set the statute of limitation to running, but proof of publication shall be filed with the clerk of the court in which the cause is pending at any time before a decree of final discharge shall be rendered; and the time for filing proof of publication shall not be limited to the ninety-day period in which creditors may probate claims.
