Child Custody Attorneys St. Louis MO | Thompson & Walker | Thompson & Walker Family Law St. Louis

Quick Answer

Missouri courts make custody decisions based entirely on the best interests of the child. That means every factor — from each parent's relationship with the children to work schedules to living arrangements — is examined. Thompson & Walker builds custody cases that put your children first and your parental rights front and center.

Types of Custody in Missouri

Legal Custody: Decision-making authority over the child's education, healthcare, and religious upbringing. Missouri courts strongly prefer joint legal custody, allowing both parents to share major decisions.

Physical Custody: Where the child primarily lives. Courts can award joint physical custody (shared time) or sole physical custody to one parent with visitation to the other.

Best Interests Standard

Missouri courts apply a multi-factor best interests test under RSMo § 452.375, including: each parent's wishes; the child's adjustment to home, school, and community; the mental and physical health of all parties; the willingness of each parent to support the child's relationship with the other; and the child's own preferences (given weight based on age and maturity).

Parenting Plans

Missouri requires a detailed parenting plan in every custody case. Thompson & Walker drafts comprehensive parenting plans that cover holiday schedules, school-year routines, decision-making protocols, and dispute resolution procedures — minimizing future conflict.

Custody Modifications

Once a custody order is entered, modifying it requires showing a "substantial change in circumstances" under RSMo § 452.410. Relocation of a parent, remarriage, changes in the child's needs, or a parent's inability to provide a stable environment may qualify. We handle modifications efficiently and strategically.

Missouri Law: RSMo § 452.375 (custody), RSMo § 452.377 (relocation), RSMo § 452.410 (modification), RSMo § 452.402 (grandparent visitation)

Frequently Asked Questions

At what age can a child choose which parent to live with in Missouri? ▾

Missouri law doesn't set a specific age. Courts give increasing weight to a child's preference as they mature — generally around 12–14 years — but the preference is just one factor in the best interests analysis and is never automatically determinative.

Can a parent relocate with the child after divorce? ▾

Not without notice and potential court approval. Missouri RSMo § 452.377 requires 60 days' written notice before relocating more than 100 miles from the child's current address. The other parent can object and request a hearing.

What is a Guardian ad Litem? ▾

A Guardian ad Litem (GAL) is an attorney appointed by the court to represent the best interests of the children — not either parent. GALs investigate, interview the children and family, and make recommendations to the court. Having experienced counsel is critical when a GAL is involved.

Can grandparents get custody or visitation in Missouri? ▾

Yes. Missouri RSMo § 452.402 allows grandparents to petition for visitation rights in certain circumstances, including when a parent has died, the parents are divorced, or the child lived with the grandparent for at least six months.

How long does a custody case take in Missouri? ▾

Uncontested parenting plans can be finalized in 30–90 days. Contested custody cases typically take 6–18 months, depending on the complexity of issues and whether a Guardian ad Litem investigation is required.
