At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Legality and application of electronic signatures or digital signatures depend on the country or state to where you or your client is located. You can check this page for the effect and validity of digital signatures in different countries: https://en.wikipedia.org/wiki/Digital_signatures_and_law
I believe they are valid as long as the user is well informed about the terms and you both have an agreement.
Currently, we have 5 signature related widgets.
The most advance and what we recommend is the Adobe DC eSign Services widget. Forms are also SSL enabled, making sure that connection is secure and private when the form is being viewed and submitted.
I hope that helps.
