Indiana Code Title 5. State and Local Administration § 5-1-3-2

Sec. 2. (a) Whenever any existing statute requires the manual execution, attesting or authentication of any obligation issued by any public entity named in IC 5-1-1-1 by one (1) or more officials or persons, facsimile signatures or electronic signatures of the officials or persons may be used instead of and with the same force and effect as manually executing the obligations, including the signature of the officials or persons or of any trustee, paying agent, registrar, co-registrar, transfer agent, or other fiduciary charged with authenticating the obligations.

(b) Any obligation executed by the facsimile signature or electronic signature of officials or persons is valid and binding, if the officials or persons satisfied the provisions of the statute under which the obligation is issued on the date that the signature was printed on the obligation, even if the obligation is delivered after the official or person whose facsimile signature or electronic signature appears thereon no longer satisfies the provisions of the statute.
