§ 2-7-704 — Affidavit and other required supporting documentation

(a) Every claim which is due, when filed with the clerk
shall be supported by the affidavit of the claimant or someone
in his behalf, that the account is justly due, that no payments
have been made thereon which are not credited and there are no
offsets to the same to the knowledge of the affiant. If the
claim is not due when filed or is contingent the particulars of
the claim shall be stated. The personal representative may also
require satisfactory vouchers or proofs to be produced in
support of the claim.
(b) If the claim is founded on a bond, bill, note or any
other instrument, a copy of the instrument shall accompany the
claim. The original instrument shall be exhibited to the
personal representative, if demanded, unless it is lost or
destroyed, in which case the claimant shall accompany his claim
by his affidavit containing a copy or particular description of
the instrument and stating its loss or destruction. If the claim
or any part thereof is secured by a mortgage or other lien which
has been recorded in the office of the county clerk of the
county in which the land affected by it lies, it is sufficient
to describe the mortgage or lien and refer to the date, volume
and page of its record.
