Claim submission and verification in personal guarantor insolvency requires proof, prompt verification, estimation, and foreign currency valuation. Submission of a creditor's claim in the personal guarantor insolvency resolution process must be made to the resolution professional with proof, in the notified form and within the time stated in the public notice. The creditor bears the cost of submission and may prove the claim through information utility records or other documentary evidence. The resolution professional may seek further clarification, verify claims promptly, estimate uncertain amounts, revise admitted claims on new information, and value foreign currency claims in Indian currency at the official exchange rate on the commencement date.
