Nebraska Uniform Commercial Code 9-704
A security interest that is enforceable immediately before July 1, 2001, but which would be subordinate to the rights of a person that becomes a lien creditor at that time:
(1) remains an enforceable security interest for one year after July 1, 2001;
(2) remains enforceable thereafter if the security interest becomes enforceable under section 9-203 on July 1, 2001, or within one year thereafter; and
(3) becomes perfected:
(A) without further action, on July 1, 2001, if the applicable requirements for perfection under this article are satisfied before or at that time; or
(B) when the applicable requirements for perfection are satisfied if the requirements are satisfied after that time.
Laws 1999, LB 550, § 207.
Example: A security interest has attached under former article 9 but is unperfected because the filed financing statement covers "all of debtor's personal property" and controlling case law in the applicable jurisdiction has determined that this identification of collateral in a financing statement is insufficient. On July 1, 2001, the financing statement becomes sufficient under section 9-504(2). On that date the security interest becomes perfected. (This assumes, of course, that the financing statement is filed in the proper filing office under this article.)
