Reasons for Child Custody Modification
It is a fact that life changes. However, when circumstances change, a child custody modification is often needed to adjust the pre-existing order and set up more appropriate guidelines for custody and visitation.
Reasons to modify custody include:
- Changes to job or income: a significant change in income might make current visitation unworkable, or if a parent's schedule or job status changes, the current visitation schedule may no longer be possible.
- Relocation: in addition to determining whether relocation is permitted, new schedules will need to be established to ensure that both parents are able to maintain a relationship with the child.
- Remarriage: to determine if modification of child custody is necessary, the parents should consider if and how the remarriage affects the children.
- Disability or illness: a parent or child who is disabled may need additional help for frequent medical care, special diets, or development of any other special needs.
- Abuse or neglect: if one parent has been abusive or neglectful to the child, the other parent will want a child custody modification to limit access to the abusive parent.
- Changes in the child: as children age, their wishes may change. Additionally, the child's needs may change as they age, making one home or the other more suitable.

Frequently Asked Questions (FAQs) About Child Custody Modifications in Missouri
Can I modify custody without going to court?
- In some cases, yes. If both parents agree to the custody modification, they can submit a mutual agreement to the court for approval. However, if there is a dispute, a court hearing will be required.
Does my child get to choose which parent to live with?
- The court may consider the child’s preference, especially if they are older and mature enough to express a reasoned choice. However, the final decision is always based on what is in the child’s best interests, not just their preference.
Can I move out of state with my child after modifying custody?
- If you plan to relocate, you must notify the other parent and the court at least 60 days in advance. The other parent can contest the move, and a judge will determine whether relocation is in the child’s best interest.
What happens if the other parent doesn’t follow the new custody order?
- If a parent violates the modified custody order, you can file a motion for enforcement with the court. The judge may impose penalties, modify the order further, or even adjust custody arrangements in response to repeated violations.
Will Modifying Custody Affect Child Support Payments?
- Yes, a change in custody may impact child support obligations. The parent who gains more custody time may receive more child support, while the other parent may see a decrease in their payments. If you believe the court’s decision was unfair or incorrect, you may have the option to file an appeal to request a review of the ruling. Appeals must be filed within a specific timeframe and require a strong legal argument.
How often can I request a custody modification?
- There is no strict limit, but courts discourage frequent modifications unless a major change in circumstances occurs. Filing too often without valid reasons may result in the court dismissing your request.
Can grandparents or other family members request custody modifications?
- In certain cases, grandparents, step-parents, or other guardians may seek custody modifications if they can prove that the current arrangement harms the child or that the parents are unfit.
