The major difference between a legal separation and a divorce is that if you have a legal separation, you are still married. The wife may not resume using her former name. If you decide you want to end your marriage after a legal separation is complete, you will need to go through the court process to get divorced. Some couples choose legal separation because of religious beliefs or moral values against divorce. In other cases, there may be insurance or other financial reasons for a legal separation.
Also, divorce in the court system is public domain. Anybody can sit in court and hear the specifics of your divorce. On the other hand, mediation is confidential, private and conducted behind closed doors. In mediation, there are no attorneys putting up walls between you and your spouse. Mediation is about working together, doing things in the best interests of your children and focusing on being able to be parents for your children for years to come. Unfortunately, divorce in the court system is designed to put up that wall and limit communication, which inevitably leads to many post divorce problems and many more hours and thousands of dollars in court.
