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.
After the VA has made its original determination, the monetary benefits continue to be paid to the veteran as long as the disability continues. In certain circumstances, a veteran's disability may be re-evaluated or re-examined, after which the disability rating may be increased, decreased, or remain the same.
