Who Makes Medical Decisions for Your Child After Divorce?~ 3 min read

After your divorce, medical decisions for your child depend on whether you share joint legal custody or if one parent has sole legal custody. In Missouri, most parents have joint legal custody, which means you work together on major healthcare choices. If there are disagreements on medical issues, you can use a parenting coordinator to help make those decisions.

When you and your co-parent are no longer married, who makes medical decisions for your child can feel uncertain. Missouri law provides a structure for those decisions through joint legal custody or sole legal custody, but your agreement or court order ultimately guides how decisions are made.

In Missouri, most parents receive joint legal custody. This means you and your co-parent share responsibility for major decisions, including medical care. You talk through options, exchange information, and aim to agree on what is best for your child.

When one parent has sole legal custody, you still communicate about your child’s needs, but that parent has the final say. Many parents also choose to divide responsibilities by topic when working through Mediation or Collaborative Divorce. For example, one parent may handle medical decisions while the other handles educational or activity-related choices.

Mediation and Collaborative Divorce give you more flexibility than a court order issued after a contested hearing. You can outline exactly how decisions are made and communicated. Many parents choose to include guidelines such as:

  • How medical information is shared
  • How long each parent has to respond
  • What steps must be taken before a final decision is made

These details help lower conflict and make expectations clear for both households.

A parenting coordinator can help when disagreements continue after your divorce. In Missouri, you can use a parenting coordinator if you both agree. They first try to help you reach a resolution. If that is not possible, they will make the decision for you.

Parenting coordinators can assist with daily issues that judges rarely address, such as:

  • Exchange times and holiday schedules
  • Activities
  • Screen time
  • Transportation and appointments

They provide quicker guidance on issues that affect your child’s routine and reduce the stress of ongoing conflict.

Emergencies require immediate action. If your child needs urgent medical care, you get help first. As soon as it is safe to do so, you notify the other parent. Good communication supports your child’s wellbeing whether you share joint legal custody, or one parent has sole legal custody.

1. Does joint legal custody mean equal parenting time?
No. Legal custody addresses decision-making authority, not parenting time.

2. Can a judge appoint a parenting coordinator?
No. Both parents must agree before a parenting coordinator is appointed in Missouri.

3. What happens if we strongly disagree on a specific treatment or medication?
Joint legal custody requires collaboration. If you cannot agree, mediation or a parenting coordinator can help resolve the issue faster than pursuing a court hearing.
