There is no express provision in the Department's standard terms and conditions of purchase prohibiting the assignment of debt. The Department's standard terms and conditions of purchase do however include a prohibition on the contractor giving, bargaining, selling, assigning, subcontracting or otherwise disposing of the contract or any part thereof without the previous agreement in writing of the Department. Accordingly a contractor may not assign its debts under the contract without such approval from the Department. This reflects the OGC recommended provision in this regard.
