Your questions are too complex to respond by posting.  The spouse that originally had the home is entitled to reimbursement of the value of the equity at the time of the deed to make it joint title.  There are other factors also.  The house probably would be valued at time of trial not separation, since it is now a community home.   The military has booklets that they distribute.  I believe the community would share the benefits if a threshold number of years are met.
