Sometimes parents who are splitting up use a process called mediation to try to reach an agreement on the various decisions they have to make. The process is led by a mediator, who has been trained to act as a neutral third party in order to help people resolve their conflicts.
Unlike a judge, a mediator has no decision making power. If your parents use mediation, they will meet a few times with the mediator at his or her office. The mediator will try to help them reach an agreement that meets everyone's needs. They will not have to go to court unless they are still unable to reach an agreement.
Common-law parents — parents who chose to live together without getting married — don't have to get a divorce, because there is no marriage to end. But they do need to decide what will happen to their children and how they will divide their property.
When two people have been living together and they decide not to live together anymore, they are separated. However, when married people separate, their marriage has not yet ended. They have to get a divorce to legally end a marriage. Common-law couples don't have to get a divorce, because there is no marriage to end.
Ideally, your parents will make the decisions together about who you will live with and how that will work. Your opinion should be taken into account.
If they can't decide themselves, they might go to a mediator for help in reaching an agreement. Or they might have to go to court and have a judge make the decisions for them.
