Claims by workmen and employees: proof submission and evidence standards govern admission of dues in liquidation proceedings. Workmen and employees must submit a proof of claim to the liquidator using prescribed forms (Form E individually, Form F for collective claims), by personal, postal, or electronic means. Dues may be proved via information utility records or documents such as employment contracts, demand-and-nonpayment evidence, or adjudicating orders; absent a submitted claim, the liquidator may admit claims on the corporate debtor's books of account.
