If there is no signature on your deposit receipt, there may be a certain risk, as this may lead to someone else claiming your deposit. If you find that the deposit receipt is unsigned, you can take the following measures to correct it:

1. Contact the bank as soon as possible: If you find that the deposit receipt is unsigned, you should contact the bank as soon as possible and explain the situation. The bank will verify the true status of the deposit based on the information you provide and take appropriate measures.

2. Provide relevant evidence: In order to prove the authenticity of the deposit, you need to provide relevant evidence, such as the source of the deposit, the specific time and location, the amount of the deposit, and other information. If you have relevant evidence, you can provide it to the bank for verification.

3. Contact the banking regulatory agency: If the bank does not handle your deposit receipt issue in a timely manner, you can contact the banking regulatory agency to lodge a complaint. Banking regulators will investigate and handle complaints to protect your legitimate rights and interests.

It should be noted that unsigned deposit receipts may pose a threat to the safety of your property. Therefore, you should pay attention to keeping the deposit receipts when making deposits, and try to ask bank staff to be present when making deposits. Sign the receipt to confirm.
