Yes, an updated or revised Net Worth Certificate may be required under the following conditions:

1. Significant Change in Assets: When an individual or entity acquires or disposes of major assets (e.g., property, investments), an updated certificate may be needed to reflect the accurate net worth.

2. Liability Changes: If there are new liabilities, loans, or repayments that significantly affect the financial position, a revised certificate should be issued.

3. Time-Sensitive Requirements: Some institutions (banks, visa authorities, government agencies) may request a recent Net Worth Certificate, usually within a specific period (e.g., 3 to 6 months).

4. Compliance or Audit Requirements: Updated certificates may be required to meet regulatory compliance or audit purposes, especially for businesses.

5. For Loan or Financial Transactions: When applying for new loans, mortgages, or during investment deals, an up-to-date certificate is often necessary.

6. Legal or Tax Issues: If legal or tax-related concerns arise (e.g., estate settlements, business disputes), an updated Net Worth Certificate might be essential.

In these cases, the Net Worth Certificate must be revised by a Chartered Accountant to accurately reflect the current financial status.
