You can still live in the same home even if you wish to file for legal separation or divorce! Technically, you are separated when you no longer live together as husband and wife. If you are living in the same home but you sleep in different rooms, you are still separated. Many people cannot afford to live in different homes so they may opt to live in the same home for a period of time--but still live separately. The date of separation is very important and both parties should agree as to the date.
