Lex, let me ask you this: if you died in a car crash today, would your W be able to take care of herself and your kids in a healthy, reasonable manner?
financially, yes. I have savings that she has access to and I also have a good life insurance policy. at a minimum she should be able to make it 5 years without any additional income. she would have to get some kind of income going eventually but would have plenty of time.
logistically, I'm not sure. I have handled 100% of our affairs since day 1. if I died she would suddenly be faced with learning to drive, learning to have a budget and learning how to handle money all at once. she is smart though and i'm sure she could do it.
