Bottom line
In Missouri, child support help is handled mainly through the Missouri Department of Social Services, Family Support Division. The state child support program can help locate a parent, establish legal paternity, set up child and medical support, enforce an order, review a current order, and distribute payments.
If you need to start a case, begin with the official Missouri child support page or the child support application page. If you already have a case, keep your case number, letters, payment records, and court papers together before you call.
This guide is general information only. Child support can affect custody, safety, taxes, public benefits, and court orders. For legal advice about your case, contact a lawyer or Missouri Legal Services.
If you need help today
Child support may take time. If you need food, shelter, safety help, child care, or utility help now, do not wait for a support case to finish.
- If you are in danger, call 911. For domestic violence or sexual assault help, contact your local advocate through Missouri advocates or call the National Domestic Violence Hotline at 1-800-799-7233.
- For rent, food, utility, shelter, diapers, transportation, or local crisis referrals, search Missouri 211 or dial 211.
- For SNAP, Temporary Assistance, MO HealthNet, or child care help, start at MyDSS applications.
- For Missouri-specific help pages, see emergency help, Missouri food help, and utility assistance.
Where to start
Your best first step depends on what you already have. A parent with no order needs a different path than a parent who has an order but is not getting paid.
You do not have an order
Apply for child support services through FSD. Ask about paternity if the legal father has not been established.
You have an order
Use your case number to ask FSD about enforcement, payment tracking, address updates, employer updates, or a review.
You need court help
Use Missouri court forms only if you understand the process. For help with a hard case, contact legal aid or a family law attorney.
If you are also trying to stabilize money, housing, or child care, use this page with Missouri assistance, housing help, and child care help.
Missouri child support quick reference
| Need | Best place to start | Reality check |
|---|---|---|
| Open a child support case | Apply through Missouri DSS Child Support. | FSD will use your application to open a case, but the timeline depends on paternity, location, income records, and hearings. |
| Find the other parent | Give FSD every address, employer, phone number, birth date, and other clue you have. | Old or partial information may still help, but FSD cannot collect support from income it cannot find. |
| Set legal fatherhood | Use FSD paternity help or the Missouri Bureau of Vital Records. | A genetic test result alone may not add a father to the birth record. Follow the legal steps. |
| Estimate support | Use Missouri Form 14 and the court guidelines. | Random online calculators may be outdated, especially after Missouri’s 2026 Form 14 changes. |
| Collect unpaid support | Ask FSD about enforcement and keep payment records. | Enforcement can take longer if the paying parent changes jobs, works cash jobs, moves, or has unstable income. |
What Missouri FSD can do
Missouri’s Child Support program says it can help with locating parents, establishing paternity, starting child and medical support orders, enforcing orders, reviewing orders, and distributing collections. Services are available for the parent the child lives with and the parent the child does not live with.
FSD is not your private lawyer. If the state is involved, its job is to run the child support program and follow state law. You may still need your own legal advice if you have a custody dispute, safety concern, disputed paternity, interstate issue, or court problem.

How to apply for child support in Missouri
Missouri DSS says you can apply by submitting an application online, downloading and mailing the form, or getting an application from the nearest child support office. You can also use the state office map to find a nearby child support office.
Start with the official application page. If you cannot apply online, ask for a paper form or help from a local FSD office. For office help, use the DSS office map. For basic questions that are not case-specific, DSS also lists text and phone help on that contact page.
What to gather before you apply
| Information | Examples | If you do not have it |
|---|---|---|
| Your information | Name, address, phone, email, ID, Social Security number if available, and proof of income. | Ask FSD what other proof they can accept. |
| Child information | Birth certificate, Social Security number if available, school or medical details, and health insurance information. | Tell FSD what you can get and what you need help getting. |
| Other parent information | Full name, date of birth, Social Security number, old addresses, phone numbers, employer, relatives, vehicles, or licenses. | Give even old clues. Do not guess if you truly do not know. |
| Existing orders | Divorce decree, custody order, child support order, protection order, or prior court papers. | Ask the court clerk how to get copies if the order was filed in court. |
| Payment history | Receipts, screenshots, bank records, wage withholding notices, letters, and missed-payment notes. | Start a simple log now with dates, amounts, and notes. |
Important legal reminder
Do not rely on verbal promises, text messages, or cash payments alone when a court or administrative order says support must be paid through the official system. If the other parent pays you directly, ask FSD or a lawyer how that affects your case record before you agree to anything.
How Missouri child support is calculated
Missouri uses Civil Procedure Form No. 14 to calculate the presumed child support amount. Missouri Supreme Court Rule 88.01 says the amount calculated under Form 14 is presumed correct unless the court or agency makes the required finding that using it would be unjust or inappropriate.
Use the official Form 14 worksheet and the court’s Rule 88.01 information. Missouri Courts also issued a 2025 order adopting a new Form 14 effective January 1, 2026, so older examples may be wrong.
What can affect the amount
- Each parent’s gross income and allowed adjustments.
- The number of children covered by the order.
- Health insurance costs for the child.
- Work-related child care costs.
- Parenting time and overnight credit, if it applies.
- Other support obligations that the worksheet recognizes.
- Special facts that a court or agency may consider under Missouri law.
Do not assume the table amount is what you will receive. Form 14 is a worksheet. It starts with income and support rules, then applies adjustments. If income is unclear, self-employment is involved, or a parent is unemployed, ask for legal help before you rely on a number.
Paternity and parentage
If parents were not married when the child was born, legal paternity may need to be established before child support can be ordered. Missouri DSS says parents may complete an Affidavit Acknowledging Paternity, or a court or agency process may be needed.
Use the official paternity help page for FSD information. The Missouri Bureau of Vital Records also posts vital records forms, including paternity-related forms.
Be careful before signing any legal paternity document. It can affect support, rights, duties, and the birth record. If there is abuse, pressure, doubt about parentage, or a possible safety risk, speak with legal aid, an advocate, or an attorney before signing.
How payments are sent and tracked
Missouri DSS says support payments received by the Family Support Payment Center and the State of Missouri are generally sent to the receiving parent by direct deposit or prepaid card. Checks are issued only in certain circumstances.
If you receive support, review the official payment information page. If you do not have direct deposit, the state may use a prepaid card. Read the prepaid card page before you use the card so you understand how it works.
Payment tracking tips
- Keep your case ID in a safe place.
- Tell FSD if your address, phone, bank, or card information changes.
- Save payment records, missed-payment notes, and letters from FSD.
- Do not mix child support records with informal money requests.
- Check your case record before assuming the other parent has not paid.
If payments stop or come late
FSD may use enforcement tools when there is a support order and payments are not being made. These can include income withholding, liens, tax refund intercepts, license suspension, passport denial, court actions, criminal nonsupport referrals, and referrals to another state when needed. Employers also have duties to report new hires and withhold income for support orders.
For employer-related rules, see Missouri DSS employer information. For license-related concerns, DSS posts a license suspension FAQ.
| Problem | What to do | What not to do |
|---|---|---|
| One payment is late | Check the official payment record and write down the date. | Do not threaten the other parent or block court-ordered parenting time over money. |
| Several payments are missed | Call FSD with your case number and ask what enforcement options are active. | Do not make a side deal without understanding how it affects the case. |
| The other parent changed jobs | Give FSD the new employer, address, phone, or any clue you have. | Do not post private claims online; keep records for FSD or court. |
| The other parent moved away | Ask FSD about interstate enforcement. | Do not assume Missouri cannot help just because the other parent left Missouri. |
Changing a Missouri child support order
If life changes, you may need a review or modification. Missouri DSS says a parent may ask FSD to review a child support order every 3 years. If less than 3 years have passed, FSD may review only under special circumstances.
Review the official changing support guide. A change usually requires a new order. Falling behind because income changed does not automatically change what is owed.
Changes that may matter
- A major change in either parent’s income.
- A change in health insurance costs.
- A change in work-related child care costs.
- A major change in the child’s needs.
- A parenting-time change that affects the worksheet.
- A child becoming emancipated or reaching an age where support may end.
Missouri law has detailed rules about support after age 18, school attendance, higher education, disability, and emancipation. Read Missouri statute 452.340 and ask a lawyer before you assume support ends or continues.
If you need court forms or legal help
Some parents handle part of a case without a lawyer, but family law forms can be hard. Missouri Courts says people who represent themselves in a family law matter, including child support or paternity, must complete the Litigant Awareness Program and file the certificate with the court.
Start with Missouri Courts’ family law self-help page. If you are low income, contact Missouri Legal Services. If you need broader state help, see Missouri legal help.
If legal aid cannot take your case, you can also check Missouri Lawyers Help from The Missouri Bar for attorney search and public legal resources.
Safety, public benefits, and child support cooperation
If you receive Temporary Assistance or MO HealthNet, you may be referred to child support services automatically. If pursuing support could put you or your child at risk, ask your benefits worker or child support worker about good cause and safety options before you share information that could create danger.
Missouri DSS manuals say child support efforts may be suspended while a good cause claim is being reviewed in Temporary Assistance cases. This is not a promise that every safety request will be approved. It means you should speak up early and ask what proof or forms are needed.
Use good cause rules for background, and contact a local domestic violence advocate through MOCADSV if you need safety planning. For related ASMOM help, see domestic violence help.
Backup help while a child support case is pending
A child support case can help over time, but it may not solve this month’s bill. If you need help now, apply for the programs that match your need.
- For cash help, see Missouri TANF.
- For medical coverage, see healthcare help.
- For baby supplies, see baby gear help.
- For work or training, see job training.
Common mistakes to avoid
- Relying on outdated calculators: Missouri Form 14 changed for 2026. Use official forms and current court information.
- Ignoring letters: If FSD or the court sends a letter, read it quickly. Missing a deadline can hurt your case.
- Not reporting changes: Tell FSD if you move, change phone numbers, change banks, or get new information about the other parent.
- Making private deals: Side agreements can cause problems if they do not match the order or payment record.
- Assuming support ends at 18: Missouri law has school and emancipation rules. Check the order and the law.
- Using child support as custody leverage: Child support and parenting time are separate legal issues. Ask a lawyer before taking action.
