This problem can occur on Macintosh computers. If you are using a Mac, you will need the official Adobe PDF reader to see the checkboxes.
This reader is free.
Search in your browser for “download Adobe Acrobat reader for Macintosh.”
Once Adobe Acrobat is downloaded and installed, go to Finder > Applications, and double-click Adobe Reader. It will ask if it should be made the default PDF reader. Say Yes.
The next time you use Family Law Software to view a PDF from Court Forms, you should see the checkboxes.
