We paid a local attorney about $1000 for our will, including a trust for our estate should we both die with minor children. In retrospect, I don't think it was worth it.
Comparing the language of our document to the language the software wills generate makes it clear that the software is written by actual attorneys. There may be differences I can't see, but if there are they are not apparent.
Our attorney was patient and seemed knowledgeable, but he clearly didn't actually do anything on our will except ask his Secretary to insert our names and information into the blanks. When checking over the documents, we found a bunch of mistakes that suggested we were just reading a standardized form with the blanks filled in, not a document customized for us in any way. For example, my wife's will and my will were identical except for the name, which means I was leaving all of my assets to my husband and there were like 20 pronoun mistakes for the gender discrepancy.
So if you're intelligent enough to answer the software's questions intelligently, and you already know what it is you want, then I think the software is fine. It's been proven legally defensible in multiple states by now. You still have to print out hard copies and have them witnesses and archived, which was included in our attorney fee, but that certainly doesn't cost $1000.
Assuming that you are fine with the other spouse getting everything, are there any reasons to have a will at all if there are no children, everything is owned jointly, and the other spouse is the beneficiary on the retirement accounts?
What if you both die in an accident? I've been through this process several times with my family already and I think the will is almost useless when there is one surviving spouse. But eventually that second person will also die, and that's when the paperwork comes into play.
