What are the legal steps to an agreed change in my parenting plan?

Your parenting plan should include a section that addresses disagreements or modifications to your plan. Usually, parties attend a mediation to make any changes. Your question describes this as an "agreed change", so if the other parent is in agreement, it should be fairly easy. You might even be able to call up either or both attorneys who worked with you in the divorce to amend the parenting plan and file it with the court.

If you have an agreement, it will be fairly easy to make the changes. If your parenting plan does not have a provision that allows both parents to agree to deviate from the parenting plan, you might consider adding it. It can save time and money and add flexibility needed to co-parent. I would consult an attorney before making any changes. If the other parent doesn't agree, it could be difficult to make changes so soon after the divorce. Best of luck!
