A spousal support order does not stop being enforceable just because your ex stops paying. In Missouri, unpaid maintenance is a court-ordered debt. You can go back to the same court that issued the order and ask a judge to enforce it through contempt, income withholding, or collection against your ex’s wages and property. Your ex cannot lower or cancel the obligation on their own.
The one thing that will not work is waiting. Here is what to do instead.
Can Your Ex Legally Stop Paying Maintenance?
Only in narrow circumstances. Missouri calls spousal support maintenance, and Section 452.370 sets out when the obligation ends or changes.
Maintenance ends automatically in two situations, unless your decree or a written agreement says otherwise:
- The death of either party
- Remarriage of the spouse receiving maintenance
Outside those events, your ex has to go to court. Under Section 452.370.1, a judge can modify maintenance only on a showing of changed circumstances so substantial and continuing as to make the current terms unreasonable. A pay cut, a new mortgage, or a change of heart does not qualify on its own, and none of it authorizes self-help.
Check your decree for one more thing: whether the maintenance was ordered as modifiable or non-modifiable. Non-modifiable maintenance is not subject to later change, even if circumstances shift.
What Are Your Options When Payments Stop?
You have several enforcement paths, and they can be combined.
File a motion for contempt. You ask the court to order your ex to appear and explain the nonpayment. If the judge finds the failure was willful, the court can order payment of the full arrears, set a purge plan, impose fines, award your attorney fees, and in persistent cases order jail.
Request income withholding. Under Section 452.350, income withholding is available for maintenance orders, not just child support. Once the obligor is delinquent in an amount equal to one month’s total obligation, wages or other income can be withheld. An employer who ignores a valid withholding notice can be held in contempt and made liable for the amount that should have been withheld.
Collect on the arrears. Past-due maintenance is a debt your ex owes you, and standard collection tools such as execution against wages, bank accounts, and property may be available.
Note that the Family Support Division’s enforcement program is built around child support. Maintenance enforcement generally runs through the circuit court that entered your judgment, so a motion filed in your own case is usually the direct route.
What If Your Ex Says They Can’t Afford to Pay?
Inability to pay is a real defense in a contempt proceeding, but your ex has to prove it to the judge, not simply assert it to you.
Two things to watch for:
- A genuine, involuntary change such as job loss, disability, or a serious illness may support a modification going forward.
- Voluntary underemployment is treated differently. A person who quits or deliberately reduces income to escape maintenance may find the court unpersuaded.
Even where a modification is warranted, it usually applies from the date the motion is filed forward. Payments already missed generally remain owed. That cuts both ways: if you are the paying spouse and your circumstances truly changed, file promptly rather than quietly stopping payments.
Mistakes That Weaken Your Case
A few common missteps make enforcement harder:
- Accepting partial payments without records. Keep a written ledger of what was owed, what was paid, and when.
- Making informal side deals. A verbal agreement to reduce maintenance is generally unenforceable. Any change should go through the court.
- Waiting months or years. Delay lets arrears grow while memories and records fade, and it can raise questions about whether you treated the obligation as serious.
- Retaliating. Withholding the children or violating your own obligations under the judgment creates a second problem instead of solving the first.
How to Prepare Before You File
Bring the judge something concrete:
- A copy of your judgment showing the maintenance amount, duration, and whether it is modifiable
- A payment history listing each due date, the amount owed, the amount received, and the running balance
- Bank records showing deposits or the absence of them
- Written communications where your ex acknowledges the debt or explains the nonpayment
- Any evidence of your ex’s income, including a new job, business activity, or spending
Organized records shorten the hearing and make willfulness easier to establish.
FAQ
Can my ex go to jail for not paying spousal support in Missouri?
Yes, in a civil contempt proceeding a judge can order jail for willful nonpayment. Courts usually allow the person to purge the contempt by paying the arrears first.
Does maintenance stop if my ex remarries?
Maintenance ends on the remarriage of the spouse receiving it, and on the death of either party, unless the decree or a written agreement provides otherwise.
Can back maintenance be wiped out by a modification?
Generally no. Modifications typically apply from the filing date forward, so payments that already came due usually remain owed.
What if my ex moved out of state?
The order remains enforceable. Missouri courts keep authority over the judgment they entered, and interstate tools exist for collecting against income and assets in another state.
Getting Your Maintenance Payments Back on Track
Missed maintenance is a legal problem with legal answers. The order stands until a court changes it, and the longer nonpayment goes unaddressed, the harder collection becomes.
