The new version of UCC (Uniform Commercial Code) Article 9 on secured transactions is significantly different from the prior version. To date, 17 states have enacted the 1999 version. The text also contains extensive coverage of the prior version because the majority of states have not yet adopted the new one. Also provides an overview of the security agreement; relationship of parties prior to default; perfection of security interest; bankruptcy; and the enforcement of security interest.
I mean, nobody should go out of their way to read this just for the fun of it. But if you happen to be a lawyer who does Article 9 secured transactions from time to time but never took secured transactions in law school, this is a pretty good overview.
