The purpose of a custody order is to provide both parties with a schedule on when they have their children and no longer live in the same home. This eliminates any confusion for everyone involved, including the parents, children, teachers, coaches and others who may need to know who is supposed to pick up a child and when. This is why schools require that a custody order be on file with the school. A custody order is not only a useful tool to help everyone know when they are supposed to have the children but also it guarantees time that both parents get to spend with the child or be held in contempt. With this said, however, there are times when both parents may want to deviate from this schedule by agreement. If BOTH parties are agreeable to change anything in the custody schedule, you do not have to go back to court to do so unless you want to make it a permanent, guaranteed changed. If both parties agree to make changes, it is best but not necessary to put it in writing. It is encouraged that parties work with each other as custody orders cannot contemplate every single thing that may arise such as a wedding, party, or other event that flexibility may need to be used. Parties can always give each other extra time, makeup time, agree to switch days, etc. by agreement regardless of what the custody order says as long as both parties agree.
