Title 2 - DEPARTMENT OF AUDIT AND CONTROL
Chapter I - Audit Of Revenues And Accounts Payable From State Funds And Funds Under Its Control
Part 8 - Traveling Expenses
Section 8.13 - Advance for travel expenses

Generally, agencies are expected to provide each agency traveler with a credit care enabling the traveler to charge traveling expenses directly to the State and to avoid the need for the agency to make an advance payment to a traveler for traveling expenses. However, an agency may advance funds to a traveler for traveling expenses when it is in the best interests of the State to do so, and a traveler shall account for such a payment upon completion of the travel for which the payment was advanced.
