When your ex-spouse fails to pay court-ordered maintenance (alimony) in Missouri, you have powerful legal tools to enforce the order and collect what you are owed. Under RSMo § 452.350, Missouri courts can order automatic wage withholding, hold the non-paying spouse in contempt of court with potential jail time, place liens on real property, and intercept tax refunds. The court may also award you attorney fees for bringing the enforcement action. Missouri law treats unpaid maintenance as a serious matter, and judges have broad discretion to impose penalties that compel compliance.

How Missouri Enforces Alimony Orders
Missouri courts enforce alimony (called maintenance in Missouri law) through contempt proceedings, wage garnishment, property liens, and license suspensions. Under RSMo § 452.350, when an obligor becomes delinquent in maintenance payments equal to one month's total support obligation, the court can order automatic income withholding without further notice. Missouri law provides no exemptions from attachment or execution for property when collecting court-ordered maintenance, meaning your ex cannot shield assets from collection efforts under RSMo § 452.140.
The primary enforcement methods available in Missouri include:
- Wage garnishment through income withholding orders served on employers
- Civil contempt proceedings with potential jail time until compliance
- Property liens on real estate that prevent sale without payment
- Tax refund interception at both state and federal levels
- Professional and driver license suspension for significant arrearages
- Bank account garnishment to seize liquid assets
- Credit bureau reporting to damage credit scores
Filing a Motion for Contempt in Missouri
Filing a Motion for Contempt is the most common and effective method to enforce unpaid alimony in Missouri. The filing fee ranges from $50 to $150 depending on your county, and you must file in the same court that issued your original divorce decree. Under Missouri law, you must prove three elements to establish contempt: the existence of a valid court order requiring maintenance payments, your ex-spouse's knowledge of that order, and willful failure to comply with the payment terms.
The contempt process follows these steps in Missouri circuit courts:
- Prepare and file a Motion for Contempt with supporting documentation showing missed payments
- Pay the filing fee ($50-150) to the circuit clerk
- Serve your ex-spouse with the motion through the sheriff ($25-75) or certified mail ($10-50)
- Attend the court hearing where your ex must explain the non-payment
- If contempt is found, the court orders remedies including immediate payment, wage garnishment, or jail
Missouri courts distinguish between civil and criminal contempt in alimony enforcement cases. Civil contempt is designed to coerce future compliance and allows the contemnor to purge the contempt by paying the arrears. Criminal contempt punishes past violations. Under RSMo § 476.120, punishment for contempt may include fines, imprisonment, or both at the court's discretion.
Wage Garnishment for Unpaid Maintenance
Wage garnishment is often the most effective tool for collecting unpaid alimony in Missouri because it removes the obligation from voluntary compliance. Under RSMo § 452.350, Missouri courts can order income withholding to collect current maintenance plus arrearages. The federal Consumer Credit Protection Act limits garnishment to 50% of disposable earnings if the obligor supports another spouse or child, or 55% if the arrears exceed 12 weeks of payments. Without another dependent, the limits increase to 60% and 65% respectively.
Key provisions of Missouri wage garnishment for maintenance include:
- Automatic withholding triggers when arrears equal one month of the support obligation
- Employers must comply within 14 days of receiving the withholding order
- Employers who fire or discipline employees due to withholding orders face penalties under RSMo § 452.350(6)
- Multiple support orders are satisfied on a pro-rata basis up to federal limits
- Withholding continues until the court terminates or modifies the order
Property Liens and Asset Seizure
Missouri law allows courts to place liens on real property to secure unpaid maintenance obligations. Under RSMo § 452.080, when alimony is decreed in gross, the decree becomes a general lien on all real estate owned by the paying spouse in the county where judgment was entered. This lien remains valid for 10 years and can be renewed if the judgment itself is renewed. The lien prevents your ex from selling, refinancing, or transferring property without satisfying the maintenance debt.
Property enforcement options in Missouri include:
- Judgment liens on real estate that attach automatically for lump-sum alimony awards
- Writs of execution allowing sheriffs to seize and sell personal property
- Bank account garnishment to freeze and seize liquid assets
- Retirement account garnishment (qualified plans are not exempt from maintenance collection)
- Interception of state and federal tax refunds through the Missouri Family Support Division
Under Missouri law, your ex cannot claim the standard homestead exemption of $15,000 against a maintenance judgment. The statute explicitly states that no property shall be exempt from attachment or execution in proceedings to collect alimony or maintenance.
Interest on Unpaid Alimony Arrears
Missouri awards interest on unpaid maintenance at a rate of 9% per annum under RSMo § 408.040. This interest begins accruing from the date each payment becomes due and continues until the full amount is paid. For example, if your ex owes $24,000 in maintenance arrears accumulated over two years, the 9% annual interest would add $2,160 in the first year alone, bringing the total owed to $26,160.
Interest calculations in Missouri maintenance enforcement:
| Arrearage Amount | Annual Interest (9%) | Total After 1 Year | Total After 2 Years |
|---|---|---|---|
| $6,000 | $540 | $6,540 | $7,129 |
| $12,000 | $1,080 | $13,080 | $14,257 |
| $24,000 | $2,160 | $26,160 | $28,514 |
| $48,000 | $4,320 | $52,320 | $57,029 |
The court will calculate interest when entering a judgment for arrears, and your ex becomes responsible for your attorney fees incurred in the collection effort.
Driver License Suspension for Non-Payment
Missouri can suspend the driver license of a person who fails to pay court-ordered support, including maintenance in some circumstances. Under RSMo §§ 454.1000 to 454.1031, the Missouri Family Support Division (FSD) may order the Department of Revenue to suspend driving privileges when the obligor owes either $2,500 in past-due support or an amount equal to 3 months of current payments, whichever is lower. While this enforcement tool is most commonly used for child support, it can apply when maintenance and child support are combined in a single order.
The license suspension process in Missouri follows these steps:
- FSD sends a Notice of Intent to Suspend License by certified mail
- The obligor has 60 days to enter a payment agreement or contest the suspension
- If no action is taken, DOR suspends the license
- The obligor must pay arrears in full or enter a payment agreement to reinstate
- Additional DOR reinstatement fees apply (typically $20-45)
Professional License Suspension
Missouri courts can order the suspension of professional licenses for non-payment of maintenance as part of contempt sanctions. This enforcement tool can affect doctors, lawyers, nurses, teachers, contractors, real estate agents, and other licensed professionals. The threat of losing the ability to earn a living in one's profession often motivates compliance more effectively than other remedies. Missouri courts typically reserve license suspension for cases involving willful non-payment where other enforcement methods have failed.
The Role of Family Support Division
The Missouri Family Support Division (FSD) provides enforcement services primarily for child support but can assist with maintenance enforcement when it is combined with child support in a single order. FSD services include locating the obligor, establishing income withholding, intercepting tax refunds, reporting to credit bureaus, and filing contempt actions through the prosecuting attorney. FSD services are available at no cost to custodial parents, though the agency's primary focus is child support rather than maintenance-only cases.
FSD enforcement tools include:
- Income withholding orders sent directly to employers
- Federal and state tax refund interception
- Credit bureau reporting of past-due amounts
- License suspension referrals to state agencies
- Interstate enforcement through the Uniform Interstate Family Support Act (UIFSA)
- Prosecution referrals for criminal non-support charges
To apply for FSD services, contact the Child Support Call Center at 1-866-313-9960 or visit your local FSD Resource Center.
What Your Ex Can and Cannot Argue
Missouri courts require the obligor to demonstrate inability to pay before avoiding contempt sanctions. Under Missouri case law, contempt lies when there is an actual violation of the court order and either the contemnor was able to comply or the contemnor intentionally placed themselves in a position where they could not comply. Your ex cannot simply claim they lost their job or experienced reduced income without proving they made good-faith efforts to maintain their earning capacity and seek employment.
Common defenses that Missouri courts reject include:
- Voluntary unemployment or underemployment without justification
- Quitting a job to reduce income and avoid payments
- Transferring assets to family members or new spouses
- Claiming bankruptcy (maintenance obligations are non-dischargeable)
- Arguing the amount is unfair (the remedy is to file for modification, not stop paying)
Valid defenses that Missouri courts may accept include:
- Documented medical disability preventing employment
- Involuntary job loss with evidence of active job searching
- Incarceration (though arrears continue to accrue)
- Court-ordered modification reducing or terminating the obligation
- Full payment of all amounts due
Collecting Across State Lines
When your ex moves to another state, Missouri courts can still enforce maintenance orders through the Uniform Interstate Family Support Act (UIFSA), adopted in Missouri under RSMo Chapter 454. UIFSA allows Missouri to maintain continuing exclusive jurisdiction over maintenance orders, meaning your ex cannot escape the obligation by relocating. You can register your Missouri maintenance order in the new state and use that state's enforcement remedies, or you can continue enforcement actions in Missouri and have judgments enforced in the other state.
Interstate enforcement options include:
- Registering the Missouri order in the new state of residence
- Direct income withholding served on out-of-state employers
- Federal tax refund interception regardless of where your ex lives
- Contempt proceedings in Missouri requiring your ex to appear or face arrest
- Full faith and credit recognition of Missouri judgments in all 50 states
Timeline for Alimony Enforcement in Missouri
The enforcement process in Missouri typically takes 60 to 180 days from filing a Motion for Contempt to receiving court-ordered remedies. Wage garnishment can be implemented faster because it does not require a hearing when the obligor is already delinquent by one month. The timeline depends on whether your ex contests the contempt allegations, the court's docket, and the complexity of asset discovery if you are seeking property liens or seizure.
| Enforcement Action | Typical Timeline | Filing Fee |
|---|---|---|
| Motion for Contempt | 60-90 days to hearing | $50-150 |
| Wage Garnishment Order | 14-30 days after court order | Included in contempt |
| Property Lien Recording | 7-14 days after judgment | $20-50 recording fee |
| Tax Refund Interception | Next tax filing season | No additional fee |
| License Suspension | 60-90 days after FSD notice | No fee |
Attorney Fees in Enforcement Actions
Missouri courts routinely award attorney fees to the prevailing party in maintenance enforcement actions. Under RSMo § 452.355, the court may order a party to pay a reasonable amount for the costs and attorney fees of the other party. When you successfully prove contempt, the court will typically order your ex to pay your legal costs in addition to the maintenance arrears, interest, and any fines. This provision ensures that enforcement does not cost you more money than you recover.
Typical attorney fee ranges for Missouri maintenance enforcement:
- Simple contempt motion (uncontested): $1,500 to $3,500
- Contested contempt with hearing: $3,500 to $7,500
- Complex enforcement with asset discovery: $7,500 to $15,000
- Interstate enforcement actions: $5,000 to $12,000
Modification vs. Enforcement
If your ex claims they cannot afford to pay, the proper remedy is to file a Motion to Modify maintenance rather than simply stop paying. Under RSMo § 452.370, modification requires proving a substantial and continuing change of circumstances that makes the original order unreasonable. Until a court grants modification, the original maintenance amount remains due and enforceable. Your ex cannot retroactively reduce payments for periods before filing the modification motion, and the court cannot forgive arrears that accumulated before the motion was served.
Important modification rules in Missouri:
- Modification is only prospective, not retroactive beyond the filing date
- The burden of proof is on the party seeking modification
- The order must be modifiable (some maintenance awards are non-modifiable)
- Both increases and decreases are possible depending on changed circumstances
- Cohabitation or remarriage may be grounds for termination, not modification
