As used in Code Sections 44-14-162.2 through 44-14-162.4, the term "debtor" means the grantor of the mortgage, security deed, or other lien contract. In the event the property encumbered by the mortgage, security deed, or lien contract has been transferred or conveyed by the original debtor, the term "debtor" shall mean the current owner of the property encumbered by the debt, if the identity of such owner has been made known to and acknowledged by the secured creditor prior to the time the secured creditor is required to give notice pursuant to Code Section 44-14-162.2.
