Proof of claim by financial creditors in liquidation requires detailed disclosure of debt, security, set-off, and supporting documents. Form D prescribed the proof of claim format for financial creditors in liquidation, requiring details of the creditor, claim amount, nature of debt, supporting documents, any court or tribunal order, manner of incurring the debt, mutual dealings for set-off, security held, whether any security interest was relinquished, assignment or transfer of debt, bank details for distribution, and an affidavit verifying the claim and disclosed set-off or satisfaction. The form was later omitted.
