Within three months after appointment, a personal representative, who is not a special administrator or a successor to another representative who has previously discharged this duty, shall prepare and file an inventory of property owned by the decedent at the time of death, listing it with reasonable detail and indicating as to each listed item its fair market value as of the date of the decedent's death and the type and amount of any encumbrance that may exist with reference to any item.

The personal representative shall send a copy of the inventory to interested persons who request it and shall file the original of the inventory with the court.

The personal representative may employ a qualified and disinterested appraiser to assist him in ascertaining the fair market value as of the date of the decedent's death of any asset the value of which may be subject to reasonable doubt. Different persons may be employed to appraise different kinds of assets included in the estate. The names and addresses of any appraiser shall be indicated on the inventory with the item or items he appraised.

If any property not included in the original inventory comes to the knowledge of a personal representative or if the personal representative learns that the value or description indicated in the original inventory for any item is erroneous or misleading, the personal representative shall make a supplementary inventory or appraisement showing the market value as of the date of the decedent's death of the new item or the revised market value or descriptions and the appraisers or other data relied upon, if any, and file it with the court and furnish copies thereof or information thereof to persons interested in the new information.
