Section 47-8-601 - Savings clause(a) This chapter does not affect an action or proceeding commenced before this chapter takes effect.(b) If a security interest in a security is perfected on January 1, 1998, and the action by which the security interest was perfected would suffice to perfect a security interest under this chapter, no further action is required to continue perfection. If a security interest in a security is perfected on January 1, 1998, but the action by which the security interest was perfected would not suffice to perfect a security interest under this chapter, the security interest remains perfected for a period of one (1) year after January 1, 1998, and continues perfected thereafter if appropriate action to perfect under this chapter is taken within that period. If a security interest is perfected on January 1, 1998, and the security interest can be perfected by filing under this chapter, 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. A financing statement securing only investment property filed during the one-year period permitted in this section shall not be subject to the indebtedness tax on recorded instruments imposed under § 67-4-409(b).
