UDIN (Unique Document Identification Number): CAs must generate a UDIN for each Net Worth Certificate they certify. This number is a unique identifier that helps in verifying the authenticity of the document online, adding an additional layer of security and trustworthiness to the certification process. CA's Seal and Signature: The Chartered Accountant's seal and signature are mandatory on the Net Worth Certificate. These elements signify the CA's approval and validation of the financial information presented in the certificate, indicating that it has been thoroughly reviewed and found accurate. Date and Location: The date and location of the CA's signature are also required on the certificate. This information provides context regarding when and where the certification was performed, adding to the document's traceability and validity.
