Hello,

Thank you for reaching out here in the DocuSign Community.

I understand you would like to change the date format on your documents.

You can apply changes to any envelope or recipient that has not been marked as completed.  

Once a recipient completes their action (or the envelope), the system will not accept any further alterations. 

You can find more details regarding how to correct an envelope, here: https://support.docusign.com/en/guides/ndse-user-guide-correct-documents 

Is the date a Date Signed field or a Text field?

Let us know if you need further assistance with this.

Best regards,
