Proof of claims by workmen: submission requirements and evidentiary routes govern employee dues in insolvency. Proof of claims by workmen and employees must be submitted to the interim resolution professional in person, by post or electronically in the prescribed form; supplementary documents or clarifications may be furnished before constitution of the committee. An authorised representative may file a consolidated claim for numerous workmen or employees. Dues may be proved by information utility records or other documents, including employment contracts, notices demanding payment with proof of non-payment, or a court or tribunal order adjudicating non-payment.
