No, you can’t use a Child Visitation Letter to change your visitation schedule. The letter is only for planning visits or informing the other parent of a breach in your agreement. Changing your visitation schedule or rights is a formal process that must follow child decision-making responsibility and parenting time laws and may require a judge's approval. By making it more difficult for parents to change the visitation schedule spontaneously, these laws help ensure children and visitation aren’t used as leverage in a dispute between parents. As far as the law is concerned, the child's best interests always come first. For example, suppose your visitation agreement allows you to visit your children every weekend and the other parent wants to change visitation to every other weekend. In that case, the other parent can't simply make that change on their own. They may need a court order before making any modifications to your arrangement.
