Ind. Code § 26-1-8.1-0.3
If a security interest in a security is perfected before July 1, 1996, and the action by which the security interest was perfected would suffice to perfect a security interest under this chapter, as added by P.L.247-1995, no further action is required to continue perfection. If a security interest in a security is perfected on July 1, 1996, but the action by which the security interest was perfected would not suffice to perfect a security interest under this chapter, as added by P.L.247-1995, the security interest remains perfected for a period of four (4) months after the effective date and continues perfected thereafter if appropriate action to perfect this chapter, as added by P.L.247-1995, is taken within that period. If a security interest is perfected on July 1, 1996, and the security interest can be perfected by filing under this chapter, as added by P.L.247-1995, a financing statement signed by the secured party instead of the debtor may be filed within that period to continue perfection or thereafter to perfect.
