In the 1990's, I used "Willmaker" by NoloPress to generate a will. Recently, I wanted to update it, and found Quicken Willmaker 2016 available for checkout at my local library. It includes a software CD that allowed me to install the program, and generate a valid will for my area in less than an hour. One of the first things you do is give it your address, and the software generates the wording valid in your region.
The blurb on Willmaker 2016 says wills are valid in various countries including: "Australia · Brazil · Canada · China · France · Germany · India · Italy · Japan · Mexico · Netherlands · Spain · United Kingdom".
If the library (free) isn't an option, there's always Amazon
