The short answer is yes, you can. Nevertheless, I would never advise someone to do so. The "one size fits all" approach with these kits or internet sites often causes great problems and unintended consequences. Those problems often are not realized until after the person has passed away, and the ability to change or correct those problems are extremely limited if not nonexistent. All attorneys have also seen do-it-yourself documents that are simply invalid under state law. There is no replacement for the peace of mind it gives to have an experienced attorney draft these documents to your exact specifications and knowing that things will go smoothly upon your incapacity or passing.
