According to Baidu Library, if the secretary or dean is not in charge of finance, they may not be able to sign directly when it comes to financial reimbursement or signing relevant documents. In this case, the signing process usually follows the rules of the organization. In some organizations, the signature of the supervisor in charge of finance or special financial personnel may be required. These people are usually responsible for financial management and approval in the organization, and they have the power and responsibility to sign and approve financial matters.

In some cases, if the secretary or dean has a specific understanding of some financial matters or needs to give advice, they can participate in the discussion or give advice, but this does not mean that they sign directly.
