This might not be the right board for this, but might apply to those who are interested in premarital or pre-cana counseling:
At the risk of sounding macabre, FI and I are creating heathcare directives and wills prior to our honeymoon just in case the unthinkable happens, and I found a website for free, fast, and legally-binding wills, called willing.com, which I wanted to share if anyone else is interested.
That site also has an upgrade cost if you want your heathcare advance directive/POA form, but I found that you can also get that free elsewhere if you hunt a little. For instance, I live in Pennsylvania, and when I looked on pa.state.us, I searched for 'advance directive' and found a link to create one that's also free.
Good luck and happy planning!
