Creditor claim proof form requires detailed debt particulars, security disclosure, and secured creditor election on enforcement rights. Claim with proof by a creditor under the insolvency resolution process for personal guarantors to corporate debtors requires submission of a prescribed claim form to the resolution professional with creditor identification, addresses, contact details, amount claimed including interest, supporting documents, dispute details, manner and date of incurrence of debt, set-off particulars, retention of title arrangements, transfer account details, and details of any security held. A secured creditor must indicate whether it agrees to forfeit the right to enforce security during the repayment plan period, as this affects the voting share. The creditor must sign a declaration and verification confirming the truth, validity, and completeness of the claim and supporting documents.
