I've got to agree with some of the previous posters; if the couple has been together for awhile, 3+ years and are PRACTICALLY a married couple, then their income is likely in a shared account.
It depends on the couple. Even some married couples keep separate finances and have prenuptial agreements about what will happen in the event of a split.
Without some explicit agreement, every couple takes its chances on what will happen in the event that they split up later. Once you're terminating the relationship, legally you may be considered more married than you ever thought you were -- or you may be less so.
