Claims by workmen and employees require prescribed proof and permit representative filing in voluntary liquidation. Workmen and employee claims in voluntary liquidation must be submitted to the liquidator via prescribed proof of claim forms; numerous claimants may be represented by an authorized representative filing a consolidated claim. Dues can be proved by information utility records or other documents showing employment, demand and non-payment, or an adjudicatory order. If a workman or employee does not file a claim, the liquidator shall admit their claim on the basis of the corporate person's books of account.
