When you divorce, if you have children, you are required to set specific days that you and the other parent visit or look after your children. Your life, that of your ex and that of your children, will change over the years. Timings that once worked may no longer function.
Do you need to go to court to change a child custody schedule?
If you and the other parent can agree, you do not need to go to court. The courts would rather the two of you reach an agreement on your own. Learning to converse and cooperate with an ex-partner can take time. Yet, it is the best thing to do for your children.
Ideally, you and the other parent can be flexible to enable you both to spend time with your children. As your children grow older, they will likely have more of a social life outside the home. Involve them in your visitation negotiations too. There is little point making changes with their other parent if it disrupts plans the children had.
One thing to watch out for is if you are failing to comply with your visitation schedule. Even if you have a good reason, the other parent may be noting it all down to use against you. So, if you cannot make a scheduled visit you may want to record why and when.
If you and the other parent cannot agree on flexibility, you could, as a final option, go to a court and ask them to modify the child custody order.
