I like the ideas so far....hadn't thought of locations of titles/deeds. Those would be important. We have a safe deposit box (although I'm thinking about canceling and getting a safe for the house or some other potential solution), but even detailing what we have in the safe deposit box would probably be good.
My goal with it is to make the document/notebook something that is easy and doesn't require a lot of thinking. Because all of you are right...if it ever has to be used, it's probably going to be used in a time of grief and unexpected death.
Subscriptions are good. Hadn't thought of that. We don't really have any, but I should think about whehter I'm forgetting anything. My biggest concern, honestly, isn't the long-term picture. W/the right amount of term life insurance, this isn't (shouldn't) really be a problem. My immediate concern would be more related to the immediate aftermath, making sure bills get paid, making sure she has access to money that she needs, etc.
Contact info for supervisors is also good.
Always welcome to more ideas!
