When parents separate or divorce, they have to make a lot of decisions.
First, they have to decide on custody and parenting time, or who their children will live with and how that will work.
For example:
If the children live with one parent, when will they get to see the other parent? How often? And for how long? If the children live with both parents, will they stay with one parent during the week and the other during the weekend? Or will they spend one week with one parent and one week with the other?
Then parents have to decide how much money one parent has to give the other to help pay for the things their children need. This is called child support.
Parents also have to decide how they will divide all of their property (the things they own together). For example:
Each parent may have a lawyer. The lawyer's job is to help his or her client understand the laws on separation and divorce, and to help that person do what he or she thinks is best for the children.
If parents can't agree on the things they need to decide on, they have a couple of options. They can go to a mediator, and use mediation to reach an agreement. Or they might have to go to court and have a judge make the decisions for them.
