Ind. Code § 8-4-1-11
Each shareholder shall be entitled to a certificate, signed by the president or a vice-president and the secretary or an assistant secretary or the treasurer or an assistant treasurer, certifying the number of shares of stock owned by him in the company; which shares shall be deemed personal estate, and shall be transferable in the manner prescribed in the by-laws of the company; but no shares shall be transferable until all previous calls thereon shall have been fully paid in, or the shares shall have been forfeited for the nonpayment of calls thereon. Where any such certificate is signed by a transfer agent or transfer clerk and by a registrar, the signature of any such president, vice-president, secretary, assistant secretary, treasurer or assistant treasurer upon such certificate may be facsimiles, engraved or printed. In case any such officer who has signed or whose facsimile signature has been placed upon such certificate shall have ceased to be such before such certificate is issued, it may be issued by the company with the same effect as if such officer had not ceased to be such at the date of its issue. All certificates, including those heretofore issued, which are signed in facsimile, as authorized herein, shall be as valid and effectual for all purposes as if signed by the proper officers.
