(a) General rule; effect on perfection of change in governing law. A security interest perfected pursuant to the law of the jurisdiction designated in paragraph (1) of Code Section 11-9-301 or subsection (c) of Code Section 11-9-305 remains perfected until the earliest of:

(1) The time perfection would have ceased under the law of that jurisdiction;

(2) The expiration of four months after a change of the debtor's location to another jurisdiction; or

(3) The expiration of one year after a transfer of collateral to a person that thereby becomes a debtor and is located in another jurisdiction.

(b) Security interest perfected or unperfected under law of new jurisdiction. If a security interest described in subsection (a) of this Code section becomes perfected under the law of the other jurisdiction before the earliest time or event described in that subsection, it remains perfected thereafter. If the security interest does not become perfected under the law of the other jurisdiction before the earliest time or event, it becomes unperfected and is deemed never to have been perfected as against a purchaser of the collateral for value.

(c) Possessory security interest in collateral moved to new jurisdiction. A possessory security interest in collateral, other than goods covered by a certificate of title and as-extracted collateral consisting of goods, remains continuously perfected if:

(1) The collateral is located in one jurisdiction and subject to a security interest perfected under the law of that jurisdiction;

(2) Thereafter the collateral is brought into another jurisdiction; and

(3) Upon entry into the other jurisdiction, the security interest is perfected under the law of the other jurisdiction.

(d) Goods covered by certificate of title from this state. Except as otherwise provided in subsection (e) of this Code section, a security interest in goods covered by a certificate of title which is perfected by any method under the law of another jurisdiction when the goods become covered by a certificate of title from this state remains perfected until the security interest would have become unperfected under the law of the other jurisdiction had the goods not become so covered.

(e) When subsection (d) of this Code section security interest becomes unperfected against purchasers. A security interest described in subsection (d) of this Code section becomes unperfected as against a purchaser of the goods for value and is deemed never to have been perfected as against a purchaser of the goods for value if the applicable requirements for perfection under subsection (b) of Code Section 11-9-311 or Code Section 11-9-313 are not satisfied before the earlier of: (1) The time the security interest would have become unperfected under the law of the other jurisdiction had the goods not become covered by a certificate of title from this state; or

(2) The expiration of four months after the goods had become so covered.

(f) Change in jurisdiction of bank, issuer, nominated person, securities intermediary, or commodity intermediary. A security interest in deposit accounts, letter of credit rights, or investment property which is perfected under the law of the bank's jurisdiction, the issuer's jurisdiction, a nominated person's jurisdiction, the securities intermediary's jurisdiction, or the commodity intermediary's jurisdiction, as applicable, remains perfected until the earlier of:

(1) The time the security interest would have become unperfected under the law of that jurisdiction; or

(2) The expiration of four months after a change of the applicable jurisdiction to another jurisdiction.

(g) Subsection (f) of this Code section security interest perfected or unperfected under law of new jurisdiction. If a security interest described in subsection (f) of this Code section becomes perfected under the law of the other jurisdiction before the earlier of the time or the end of the period described in that subsection, it remains perfected thereafter. If the security interest does not become perfected under the law of the other jurisdiction before the earlier of that time or the end of that period, it becomes unperfected and is deemed never to have been perfected as against a purchaser of the collateral for value.
