Separation is defined as when you are no longer living together as husband and wife. You can still be in the same house but be in a state of separation. The most obvious example of this would be if a couple were no longer sharing a bed, but it can also include no longer socialising as a couple and openly treating themselves as separated in social, family or professional circles. Often people will have actually been separated in the eyes of the law for a lot longer than they think and this can have significant bearing on any subsequent divorce case or financial settlement. Of course, separation also occurs when one person simply moves out of the home and the couple no longer have sexual relations.
