Can a form include a hand drawn signature or legally acceptable signature?

The best you can do marc is actually select our form element image, create an image with the paper scanned from the signature, make the background transparent and insert the image in the form.

I believe that is the best way to placed a signature, you just have to change his dimensions and align it in order to suit well for your form. Let me know if you need any more help

My understanding is that you want to have a field wherein your users can draw their signatures digitally.

If that is correct, then I recommend you using the E-signature widget. This allows your form users to draw their signatures using their mouse, touch screen device, or any other input device that will allow them to draw their signature on your form as a confirmation or verification of consent. Please check this demo form.

We also have a Docusign widget where your form users can sign or acknowledge an agreement, even if they do not have a Docusign account. Here's a related blog post: Introducing-the-JotForm-DocuSign-Widget.

Hope that helps. If you have any questions, please let us know. Thank you.
