Require at least one signature field before sending document

[Stina-Hoehn]

Is your feature request related to a problem? Please describe.

As a document creator in LibreSign, I can send a document to a
signer without placing any signature fields. This leads to confusion
for the recipient, who receives a document but has no idea where
or whether they need to sign.

Describe the solution you'd like

LibreSign should validate before sending a document that at least
one signature field has been placed. If no signature field exists,
the send button should be disabled or a warning message should
appear, preventing the document from being sent without a
designated signing area.

Describe alternatives you've considered

Currently the only alternative is an internal policy reminding
creators to always place signature fields manually. This is
error-prone and not a reliable solution, especially for teams
with multiple users.

Additional context

This would significantly improve the user experience for both
document creators and recipients. It is a common validation
feature in other signing tools like DocuSign or Adobe Sign and
would make LibreSign more professional and reliable for
business use.

Thanks for your suggestion!

In LibreSign, a visible signature field is not required for a document to be signed. The document can be digitally signed even when no visible signature stamp is placed on the PDF.

Because of this, requiring at least one visible signature field before sending could block valid use cases where the signer only needs to apply a digital signature without a visual representation.

That said, I agree this can be confusing for some users. Instead of enforcing it globally, perhaps we could show a warning before sending or make it configurable through a policy for organizations that require visible signature fields.

If this requirement is important for your organization and you would like to prioritize its development, feel free to contact us about sponsorship or funding options.
