When you are legally separated, you are still married under the law. Some couples find it easier to live together during a legal separation because it keeps a more open line of communication, so there are no misunderstandings or secrets as to what is happening during the separation.

Can you live with someone else while separated?

Keep in mind that if your ex begins having an intimate relationship with someone while you are legally separated (but still married), then it is considered adultery. Moving a new partner into your home would be strong evidence of an adulterous relationship.
