Used PDF filler to help with guardianship papers for our grandson. Paid over $500 for help in 2010. PDF filler saved money and most important, time by being able to fill them at home and not the legal library.

It's really convenient, I've been using it to fill out paper applications since I don't like filling them out since I have dysgraphia. I have some slight issues though, like I had one application where the check box would automatically do a cross and if I want to do a checkmark I have to drag it, which I also have issues with it aligning correctly. alignment isn't too bad, but it's slightly off. Otherwise I love using this site. :D

I signed up for the free trial and ended up not needing to utilize their services. I had thought I had cancelled it, but for some reason it never went through, so I ended up getting charged for the full year. I contacted their live chat and a representative named **** was very helpful and got the refund processed right away. Thank you for being gracious and so helpful! I very much appreciate this company's customer service. I will definitely use them in the future! :)"
