What must a debtor do regarding the security agreement to show assent?

To demonstrate assent to a security agreement, the debtor must provide a clear indication of consent that aligns with the requirements of the Uniform Commercial Code (UCC). This can be established through various forms of communication, including electronic forms such as email or voicemail, provided that they sufficiently evidence the debtor's agreement to the terms of the security agreement.

The use of electronic communication for assent is recognized under the UCC and related laws that accommodate modern methods of communication. Therefore, a debtor can validly show their agreement to the security agreement without the need for a physical signature, as long as they clearly convey their acceptance through an appropriate electronic medium. This flexibility reflects the evolving nature of contracts and agreements in the digital age.

The other options imply more traditional or restrictive methods of showing assent that aren't necessarily required under the UCC. For example, requiring an in-person signature may not be practical and is not the only means of indicating agreement. Similarly, written notifications to the creditor alone may lack the affirmative consent needed if they are not coupled with the clear expressions of agreement like those found in emails or voicemails. Thus, the ability to demonstrate assent through various forms of communication, such as electronic consent, is a key aspect of recognizing the validity of security agreements.
