I have dear friends (rather than family) who will be taking care of my affairs for me. I have made it as easy as possible for them. I have even written my obituary. All they will need to do is fill in what killed me and when and where my memorial service will be.
My father had his affairs in good order when we lost him, and it was a thoughtful comfort to those of us left with arrangements to make.
Yes, I believe it is very loving to think ahead and take care of your own wishes so your loved ones can grieve without additional pressures on them.
