When your parents live together, they are both responsible for taking care of you. When your parents stop living together, this might change.
Your parents might be able to agree on custody and access themselves. But if they can't agree, even with the help of a mediator, they will have to go to court and have a judge decide.
If this happens, the judge who is making the decisions will consider things like:
If one parent has custody, the other parent usually has access, which means that you visit him or her. There are lots of different ways to arrange how you spend time with the parent who has access. Visits might be for a few hours every week, or for weekends or a few days every two weeks or month. If the parent with access lives far away, access can also include keeping in touch in other ways, like phone calls, e-mails, and letters.
Access arrangements may be very specific — actually spelling out the specific hours and days for visits — or very general and flexible.
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.
