Can I have two signature boxes next to each other

Please note that you can take advantage of our "Shrink" feature to place your form fields side by side. The following guide should help you: https://www.jotform.com/help/328-How-to-Position-Fields-in-JotForm

I did check your last edited form and it seems you have enabled "Form Accessibility" setting in form which will cause placing two signature field side by side. I would suggest you to please disable "Form Accessibility" setting in your form and the shrink the signature fields. 

Please take a look at the following cloned form where I have added two signature fields side by side: https://www.jotform.com/201904979443968
