Whenever I read Matthiessen the naturalist, I am reminded of a film clip I once saw of him trying to catch a snake in the wild.
This webpage only addresses apportionment of incarcerated veterans' benefits, which is the VA's process of taking all or some of a veteran's benefits that would otherwise be reduced or suspended due to incarceration and instead paying those benefits to the veteran's eligible dependents based on their demonstrated financial need.
The VA can reduce compensation when a veteran is in any local, state or federal jail or prison for more than 60 days. On day 61, the VA can reduce the benefits; if the Veteran was receiving benefits of 20% or more, the VA can reduce the benefit to 10% (this is the current law, and could change).
