There is also something to be said for having a 3-6 month supply of cash laying around in safe places that are not banks or safe deposit boxes.
Prepping depends on likely events and likely responses to the planned for event. Watching the "Loneliness , Depression and Hypervigilance" thread makes divorce or separation look like one of the likely events to plan for. I have not been down that road, but it appears to be messy, and appears that at least some of the supplies should be maintained offsite without the knowledge of wife/girlfriend/sidepiece.
I am picturing the scenario where things come to a head one night, and one leaves on a minutes notice with the clothes on ones back and whatever was already in the vehicle.
To start fresh, a few months cash, a pistol and carbine with support gear and a weeks worth of typical clothes for your lifestyle are going to be the basics as you setup housekeeping across town or wherever, and it may be some time before you can get back to the old place.
Remember, one will be paying deposits in advance on apartments, utilities, etc. It takes cash to do that. The initial crash pad may not be in the best part of town.
There are enough of these stories and follow on anecdotes where the wife or GF either trashed or sold for cheap all the dudes stuff in the days following the breakup, that it seems worth planning around with covert and redundant supplies.
