Legal Custody versus Physical Custody in Missouri?~ 4 min read

Legal custody and physical custody serve two very different roles in a parenting plan. Legal custody focuses on who will make important decisions about your child’s life, while physical custody determines the schedule and how your child’s time is shared between you and your co-parent. Understanding how these two types of custody work together will help you create a plan that supports your child and sets clear expectations for both of you.

When you hear “legal custody,” think about decision-making. This covers the major choices that shape your child’s life.

These decisions include education, medical care, and activities. For example, you and your co-parent will want to address where your child goes to school, what doctors they see, whether they need to undergo medical procedures, and if they take medication. It also includes choices like extracurricular activities, summer camps, travel away from home without a parent, and even when your child gets a driver’s license.

If you and your co-parent share joint legal custody, you will discuss these decisions and reach an agreement together. That means communication is required, even when you disagree. A clear parenting plan helps outline how you handle these decisions.

If one of you has sole legal custody, you should still discuss major issues. The difference is that if you cannot agree, the parent with sole legal custody will make the final decision.

Physical custody focuses on time. It determines when your child is with you and when your child is with your co-parent. You might assume that joint custody means a perfect 50/50 split. That is not always the case. In Missouri, joint physical custody means the schedule is close to equal, not necessarily exact.

Missouri law starts with a presumption that joint legal custody, joint physical custody, and a 50/50 schedule are in your child’s best interest. This means the court must first consider keeping you and your co-parent actively involved in your child’s life. It is more difficult to obtain sole legal or sole physical custody unless there are strong reasons.

In many families, shared time with both parents is an important part of a child’s development. When you and your co-parent are both healthy and responsible, regular and meaningful time with each of you benefits your child, especially at a young age.

Joint custody works best when you and your co-parent communicate and focus on your child. If you and your co-parent set aside personal disagreements and prioritize your child’s well-being, your child will benefit from having strong relationships with both of you. Sometimes communication can become difficult, working with a mediator or parenting coordinator can help resolve disputes about schedules, activities, and ongoing decisions.

It is easy to focus on whether custody is labeled “joint” or “sole,” but that is not what shapes your day-to-day life. Your parenting plan and schedule determine how your child moves between homes, how holidays are shared, and how routines are maintained. That is why clarity and structure in your plan matter more than the title attached to custody. As circumstances change over time, your custody arrangement will also change to reflect your child’s evolving needs.

1. Does joint custody mean exactly 50/50 time?
No. Joint physical custody means close to equal time, but it does not have to be an exact split.

2. What happens if you both disagree under joint legal custody?
You and your co-parent will need to continue discussions until you reach an agreement. If conflict continues, additional steps such as working with a mediator or parenting coordinator may be necessary.

3. Is it possible to get sole custody in Missouri?
Yes, but it is more difficult. Courts begin with the presumption that joint custody is in your child’s best interest.

While the Courts have made it clear that they expect existing custody orders to be followed during the ongoing COVID-19 pandemic and Stay at Home Orders, issues may still arise that make it difficult for parents to exchange children during this time. For example, one parent may have been exposed and be required to self-quarantine while the children were with the other parent, and the children may not be able to immediately come over; children may be required to quarantine with a particular parent if they were exposed while with that parent; or the parties may simply be unable to travel at this time.

  • Child Temporary Power of Attorney

This situation can become complicated when the child is not currently in the care of a parent or guardian. If the child’s caretaker is not their legal guardian, they may lack the right to make these decisions, which could lead to a delay in treatment that could prove harmful to the child. A temporary delegation to an attorney in fact is a legal document that temporarily grants someone the power to make decisions regarding a child’s healthcare. These can be as short as…
