Kind of danged if you do and danged if you don't
If you do file the court will either want the money if you file 13 or want to know where every penny of it went if you used it.
If you don't file they will order that your refund be applied to your trustee of your 13.
For a 7 it is a 50 50 chance that you will get it back, if the judge orders it to be applied they take it if not and it is never talked about then chances are they won't take it.
DH is waiting on the direct deposit of his now so we will see if the judge ordered it or not.
