Great experience for me since I'm preparing from a remote location in the mountains using the e-signature feature sending to legal services for filing.

I can't verify that my completed forms are actually sent to recipients. Programs keeps requesting me to have my e-mail verified but no code is ever sent to my e-mail.
Gideon S
Excellent experience with the program. There are no problems with the age and the possibility of transformation, since it is not the Portuguese domain that is necessary for my work. Very good indeed.
