A bank employee managing properties for the bank should at the very least have what form of authorization?

The requirement for a bank employee managing properties for the bank to have written authorization to sign leases is critical for several reasons. Written authorization serves to establish a formal record of permission that outlines the employee's authority to enter into binding agreements on behalf of the bank. This formality helps to protect both the bank and the employee by ensuring clarity about the extent of the employee’s powers and responsibilities.

Written authorization also aids in compliance with legal standards and internal policies. It helps prevent misunderstandings or disputes about the employee's authorization to act, which could lead to potential liability issues. Moreover, documentation of this authorization provides necessary accountability and can assist in audits or reviews of the bank’s practices.

In contrast, other forms of authorization, such as oral permission or verbal agreements, can lead to ambiguity or confusion, making it difficult to prove that the employee was authorized to act. Approval from the bank's board, while important in some cases, is typically not necessary for everyday operational tasks such as signing leases and would likely slow down the management process unnecessarily.
