Often I will have clients or seminar attendees who ask me about the Five Wishes form. This is a form that is designed to take the legalese out of advance directives. Yes, it may be easier for the person to understand....but according to this blog post, it may also deminish the legal effect of the document. These documents may initially make estate planning more affordable, but not if in the end you need to hire a lawyer to do a guardianship or litigate a form. As I often say, it is less expensive to bring a lawyer in to set something up then to hire one to clean up a mess.
If you are thinking about advance directives, good for you. Just make sure you are investing your time and money into something that will hold up if needed.
