What should I do if the deposit in the old man's name cannot be withdrawn after his death?

When the old man dies and the deposit in his name cannot be withdrawn, you can follow the following steps:

1. Determine the heir: First of all, you need to determine the heir of the old man. This usually includes immediate family members, such as children, spouses, parents and so on. The order and distribution of heirs should follow local laws.

2. Apply for a death certificate: apply for a death certificate from the local civil affairs bureau or relevant institutions. The death certificate is an important document for the follow-up procedure.

3. Apply for notarization of inheritance: the heir needs to apply to the notary office for notarization of inheritance. The notary office will verify the identity, relationship and inheritance rights of the heirs and handle the notarization of inheritance according to local laws.

4. Handling bank formalities: The heirs need to carry death certificates, inheritance notarial certificates and other relevant documents, and go through the inheritance withdrawal procedures at the bank where the old man deposited before his death. The bank will transfer the deposit to the heir's name according to the notarial certificate and documents.

5. Pay inheritance tax (if any): According to local laws, heirs may have to pay inheritance tax. Before going through the withdrawal procedures, please consult professionals to understand the relevant tax policies.

Please note that different countries and regions may have different laws and procedures. Therefore, in the specific operation, please be sure to consult local legal professionals to ensure compliance with the law.
