ATTACHMENT. A security interest attaches to collateral when it becomes enforceable against the debtor with respect to the collateral, unless an agreement expressly postpones the time of attachment. UCC 9-203(a). See Note.
Note: Depending on the type of collateral, a security interest attaches and becomes enforceable under different circumstances. See UCC 9-203 for details. Under Previous Article 9, which is still essentially in harmony with Revised Article 9, when the three basic prerequisites of a security interest exist, i.e. agreement, value, and collateral, the security agreement became enforceable between the parties and was said to “attach.”
