Can I print a blank WillMaker document, so that I can fill it in by hand?
No, you can't print a blank version of any WillMaker document. The main reason for this is that the text of the documents-- what's included and what's not included -- depends on your answers to the interviews. So documents can only be 'built' after you've answered all of the interview questions.
If you want to see an example of any WillMaker document, use the Your Documents screen to select the document you want to create. Select the document you want to see and continue to the first (or second) interview screen. At the bottom of the first guide topic, find View an example... and click the link. This will open a completed version of the document, using fictitious data. Your actual customized document might look different, based on the interview answers you provide.
