My wife runs a local business and has lots of contacts with people who can do things - even all the trades - so I'm confident that she can manage in a crisis. We're already joint accounts on most things. She's good at dealing with people so she does most of the admin stuff and I tend to do all the practical things around the house - but I know she'll sell this place and downsize to a little bungalow as soon as possible. She's already said she won't be able to be here without me - she'll be looking for me in my usual places. We were originally intending to cash up and move together to the country within the next year or so - but now living a remote life won't be practical/possible/desirable for her alone.
I have been building a 2-storey extension on the side of the house - I got it to the point of ready for felt & battens before I collapsed. She has a builder friend who is on the case and has going to finish all the work on the house - the extension is already tiled & waterproof and he's practically finished outside. He'll be moving to the inside work maybe week after next. I've written a detailed list of all the jobs that need doing for him to work through as fast as possible to get the house ready for selling.
