Adobe Sign Checkboxes - Have at least one required

[luketheo]

Is there any way to require at least one checkbox to be checked? There doesn't seem to be a way to group them like radio buttons. Nad any conditional formatting does not seem to be sufficient.

Hi, same issue for me. 6 checkbox, at least one have to be checked before signing. I don't know how to verify it.Did you find a solution ?

I have the same question. I have a set of 9 checkboxes and I'd like to force the signer to check just one of them. However, I'm not finding a solution online. Did you find a resolution?

I think Adobe added a function to make checkboxes required. But I havent used it in a while so I dont't quite remember

I didn't. I integrated other solutions

Thanks for the response. I ended up using radio buttons since they can be grouped together and still worked for my document.
