The Official Assignee was not appointed during that period and the creditors did not take any legal challenge to the agreement or to take any steps to recover the debts.

受托人（A）在当时尚未产生而债权人并没有采取任何法律行动挑战该协议或采取行动索帐追债。

This conclusion is reinforced by the fact that the word "creditors" is coupled with the "Official Assignee" because the phrase "Official Assignee during the period of 2 years" makes no sense.

立法行文中“债权人”与“法定受讬人”并列更加强了这一结论的正确性。“两年中之法定受讬人”语焉不通。
