Creditor voting eligibility requires lodged and admitted proof of debt before the meeting, subject to specified procedural exceptions. A creditor may vote only if the creditor has lodged with the Official Liquidator a proof of the debt: for statutory meetings under section 464 and their adjournments, the proof must be lodged by the time stated in the notice; for other creditor meetings the proof must be lodged and admitted wholly or in part before the meeting date. Exceptions exclude a prior Court meeting before the statutory meeting, creditors or classes not required to prove debts, and voluntary liquidation meetings.
