How Missouri Organizes Child Support Services

Child support in Missouri is run by the Family Support Division (FSD), part of the Missouri Department of Social Services. Circuit courts issue and enforce orders. The state's statutes, mainly Chapters 452 and 454 of the Revised Statutes of Missouri, set the rules. When people search for a child support office, they are usually looking for an FSD location.

Our database lists 16 offices, and each is named a "Child Support & Social Service Office." Most share one statewide toll-free number, 866-313-9960, which routes your call to the right team. The two Jackson County offices are the exception. Independence answers at 816-325-5820, and Kansas City answers at 816-889-3166.

That shared number tells you something useful. Missouri treats child support as a statewide program with local walk-in points, not as sixteen separate agencies. Your case is tied to you and the other parent, not to a building. A caseworker in any office can generally help you with it.

What the state program actually does

FSD offers a defined set of services to either parent, or to a caregiver who is raising the child:

Families who receive cash assistance or certain other public benefits for a child are generally referred to the program and asked to cooperate. Parents can also open a case on their own. Ask a caseworker about any fees before you sign up, because federal and state fee rules can change over time.

One point surprises many people. The caseworker and the state's attorneys work for the state's child support program. They do not act as a private lawyer for you or for the other parent. If you need advice about custody or parenting time, you will need a family law attorney or a legal aid office.

Child Support Offices in Missouri: Metro Counties Versus Rural Towns

Where you live changes how you use the program. The Kansas City and St. Louis regions have more courts, more private attorneys and more office traffic. Rural counties have fewer offices, longer drives and smaller court dockets. Both can work well if you plan ahead.

Kansas City and the western metro

Jackson County has two listings. The Independence office is at 103 North Main Street, and the Kansas City office is at 615 East 13th Street. Liberty, the Clay County seat, has an office at 11 South Water Street. A parent in the northern suburbs may find Liberty easier to reach than downtown. The Jackson County page shows both of the county's offices together.

St. Louis area and the Mississippi corridor

St. Charles has an office at 3737 Harry S Truman Boulevard. Hillsboro, the Jefferson County seat, has one at 10325 Missouri 21 Business. Cape Girardeau has one at 710 Southern Expressway. Our database does not show a separate listing for the city of St. Louis, so a St. Louis parent should call 866-313-9960 and confirm which location handles the case. The Cape Girardeau County page covers the southeast river region.

The Bootheel and the Ozarks

The Caruthersville listing in Pemiscot County uses a post office box, PO Box 821. That is a mailing address, not a place to walk in, so call first. See the Pemiscot County page for details. Poplar Bluff is at 100 South Main Street in Butler County. West Plains is at 3417 Division Drive in Howell County. Rolla, in Phelps County, is at 1111 Kingshighway, and its page is Phelps County. Farther west, Joplin is at 1110 East 7th Street and Springfield is at 1410 South Kansas Expressway.

Mid-Missouri and the north

Columbia's office is at 1500 Vandiver Drive in Boone County. Parents in the university area often start with the Boone County page. Montgomery City is at 211 East 3rd Street. Memphis, near the Iowa border in Scotland County, is listed at 1 Child Support Lane. St. Joseph, in Buchanan County, is at 310 North 4th Street. Small-town offices may serve a wide area, so a phone call saves a long drive.

Preparing for a Visit or Phone Call to a Missouri Office

Most delays come from missing paperwork or missing information about the other parent. Gather what you can before you call or visit. You do not need everything, but more detail speeds up a search for a parent or an employer.

Call on a weekday morning if you can. Write down the date, the caseworker's name and your case number at the end of each call. If someone promises a follow-up, ask when to expect it. Those notes become useful if a payment goes missing or a hearing date changes.

If you cannot travel, ask what can be handled by phone, mail or online. Many routine tasks do not require a visit. Offices that are small or staffed part of the week may ask you to schedule a time.

Missouri Rules That Shape Your Child Support Case

Missouri courts calculate support with a worksheet called Form 14, under Supreme Court Rule 88.01. It combines both parents' incomes with childcare costs, health insurance and the number of children. It also reflects the time the child spends with each parent. The result is presumed correct, though a judge can depart from it by explaining why in writing.

Under Section 452.340, support generally continues until the child turns 18. If the child is still in high school, it can continue until graduation or age 21, whichever comes first. Your own order may include other terms, so read it closely.

When a parent falls behind, Missouri has several tools. Income withholding is the usual first step, where an employer sends payments straight from the paycheck. Other tools include intercepting tax refunds and reporting unpaid support to credit bureaus. The state can also seek suspension of driver's or professional licenses in some cases. Federal rules allow passport denial once arrears pass a set threshold. A court can also hold a parent in contempt.

Orders can change. Under Section 452.370, a parent can ask the court to modify support after a substantial and continuing change in circumstances. Examples include a job loss, a serious disability or a major change in the child's needs. Modification generally reaches only payments that come due after the motion is filed and served. That makes timing important. Until a judge changes the order, the old amount remains owed.

The child support program in Missouri is administered by the state's child support enforcement agency, which operates through a network of county-level offices that handle case intake, order establishment, payment processing, and enforcement across the state under the authority of Title IV-D of the Social Security Act.

Child Support Offices locations are available in 16 cities across Missouri. They are spread across 15 counties.

Cities with the highest concentration include West Plains, St. Joseph, Independence, which serve as regional hubs for child support case processing and interstate enforcement coordination for cases involving parents in multiple states.

Non-custodial parents in Missouri who are current on their support obligation and experiencing a significant change in income — such as job loss or medical disability — may be eligible to request a formal modification review through the state child support agency without having to hire an attorney.

Custodial parents in Missouri who receive public assistance are automatically enrolled in child support services as a condition of TANF or Medicaid eligibility. Parents not receiving public assistance can still apply for child support services voluntarily and typically receive the same level of enforcement assistance at little or no cost.

Choosing the Right Missouri Office for Your Situation

Missouri's offices work best when you match your question to the right place. A parent in Springfield can start with the Greene County page and the office at 1410 South Kansas Expressway. A parent in Joplin, Jasper County, can call the local office at 1110 East 7th Street or the statewide line.

Some matters belong in court, not at the front counter. Custody, parenting time and divorce are decided by the circuit court in the county where the case is filed. Many county seats also host an FSD office, including Columbia, Hillsboro, Liberty, Memphis, Montgomery City, Poplar Bluff, Rolla, St. Charles, St. Joseph, West Plains and Independence. That makes it easier to handle a court date and an agency visit on the same trip.

Whatever your location, keep copies of every order and notice. Check your payment history regularly. Report address, job or income changes quickly. These habits prevent most disputes before they start.

Child Support in Missouri: Frequently Asked Questions

The Family Support Division of the Missouri Department of Social Services runs the state's child support program. It locates parents, establishes paternity, seeks support orders and enforces them. Circuit courts still issue the legal orders, and the division works alongside them. The offices in our database carry the name Child Support & Social Service Office, and most answer the statewide number, 866-313-9960. Independence and Kansas City have their own local lines. If you are unsure which location handles your case, the statewide number is the best first call.

Often you do not. Many routine tasks, such as opening a case, asking about a payment or reporting a new address, can be handled by phone or mail. Call before you travel, especially to smaller towns. The Caruthersville listing uses a post office box, PO Box 821, so it is a mailing address, not a walk-in location. If you do visit, bring a photo ID and any court orders. Ask whether an appointment is needed, so you are not turned away or left waiting.

Under Section 452.340 of the Revised Statutes of Missouri, support generally continues until the child turns 18. If the child is still in high school, it can continue until graduation or age 21, whichever comes first. A court order or agreement may contain other terms, such as support for a child with a disability. Do not simply stop paying on a birthday. Read your order, ask your caseworker how the end date applies to your case, and confirm in writing that the obligation has ended.

Possibly. Under Section 452.370, a court can modify support when there is a substantial and continuing change in circumstances. A lasting job loss, a serious illness or a major change in the child's needs may qualify. A short dip in income usually does not. Modification generally applies only to payments that come due after the motion is filed and served, so act quickly. Until a judge signs a new order, the old amount stays due. Gather pay stubs, termination letters or medical records to support your request.

Start by contacting your caseworker and giving the latest address and employer details you have. The usual first tool is income withholding, which sends payment from the paycheck. Other tools may include intercepting tax refunds, reporting arrears to credit bureaus and seeking suspension of driver's or professional licenses. Federal rules also allow passport denial when arrears pass a set amount. In serious cases, a court can hold a parent in contempt. Enforcement takes time, so keep records of what you have and have not received.

Unmarried parents can sign a paternity acknowledgment, often at the hospital when the child is born. Once signed and filed, it carries legal weight, though federal rules allow a short window to rescind it, generally 60 days. If the father's identity is disputed, genetic testing can be arranged through the child support program or ordered by a court. After paternity is established, support can be set and enforced. Ask a caseworker which route fits your situation, and bring the child's birth certificate.
