Noooo! I know well about that too...unfortunately. No, we are only 40 (kids are 16, 14 and 14)...I am talking about when our kids are starting their families and DH and I are living in FL close to WDW (where we wouldn't need to stay on property).Okay, I feel the need to chime in on behalf of your kids. If you are talking about them fighting it out after you've passed away, let me tell you that you are really setting them up for family issues. As someone who is an executor of my father's estate, seeing as how there were some things that he could have taken care of before he passed but didn't/chose not to has really made things interesting.
The one thing my wife and my in-laws have learned from my experience is to have it all written out to save the survivors the troubles that may arise. You might not have an idea how the deceased can take care of problems before they arise by sorting things out before they die, but take my word, don't let them "fight it out".
