I hear you about being the organized one. More than a year ago after STBX left, I copied the digital versions of her tax forms, photos etc out to free internet storage and emailed her a link along with a deadline after which I would delete the files.
Fast forward to the settlement meetings. She'd forgotten the passwords and her lawyer tried to get me to provide tech support and recover the files. Nope.
Mind you, I wasn't surprised at all and had asked D25 to make a copy for her mother before I deleted the files. That would have required her to have more than superficial conversations with her daughter though I suppose. I expect that she doesn't know that everything is safely stored still.
One of the advantages of having adult kids is the fact that I don't have to organize anything. I'm sure you and I could dream up a dozen ways to "help" our former partners have the information they need and to smooth their paths for them, but we got fired from that job. Hopefully these are things that the kids can empower themselves to do on their own - but we do have a tough time stopping being "Mom and Dad" and also being the "fix it".
PS - I'm glad your son wasn't injured in his car accident. They can be scary things. My own son doesn't even have his license although he knows that he would get a free car (my old one with 450,000km on it) if he did.
One a semi-related note - I believe he's off Christmas shopping at long last with "20-something". Not that they told me, she came up to me, gave me a huge hug and said "I'm stealing your kid". I'd been tempted to ask him if he needed transport, or funds for Christmas shopping and am proud of myself for not trying to "fix" things for him. If for Christmas I get some of his time and perhaps some of the fresh bread that he makes so well, I will be a content father.
