Missouri courts award spousal maintenance under RSMo § 452.335, which grants judges broad discretion to determine the type, amount, and duration of support payments. Unlike states with fixed alimony formulas, Missouri has no statutory guidelines for calculating maintenance amounts or duration, meaning each case is decided based on individual circumstances. The court may award temporary maintenance during divorce proceedings, rehabilitative maintenance for skill-building, or long-term modifiable maintenance for spouses unable to achieve self-sufficiency. Understanding the types of alimony in Missouri is essential for anyone navigating dissolution proceedings in the Show-Me State.

How Missouri Defines Spousal Maintenance
Missouri uses the term maintenance rather than alimony to describe court-ordered spousal support payments following dissolution of marriage. Under RSMo § 452.335, a Missouri court may award maintenance to either spouse when the requesting party lacks sufficient property to provide for reasonable needs and is unable to support themselves through appropriate employment. This two-prong threshold test must be satisfied before any type of maintenance can be ordered, making Missouri one of approximately 25 states requiring specific eligibility findings before awarding support.
The Missouri legislature deliberately avoided creating a formula-based maintenance calculation system. Courts retain significant discretion to craft maintenance orders tailored to each family's circumstances. This flexibility allows judges to consider the standard of living established during a 25-year marriage differently than a 5-year marriage, and to account for health limitations, caregiving responsibilities, and career sacrifices that vary widely between divorcing couples. The maintenance order must specify whether payments are modifiable or non-modifiable, a critical distinction that affects both parties' long-term financial planning.
Missouri courts may award maintenance as a lien against real property under RSMo § 452.080, providing additional security for the receiving spouse. When maintenance is decreed in gross as a lump sum, the decree becomes a general lien on the paying spouse's real estate, similar to other civil judgments. This enforcement mechanism distinguishes Missouri from states that rely primarily on wage garnishment for maintenance collection.
Temporary Maintenance (Pendente Lite)
Temporary maintenance, legally termed pendente lite support, provides financial assistance to a dependent spouse during the divorce process itself, typically lasting 3 to 18 months depending on case complexity. Missouri courts award temporary maintenance to ensure both spouses can maintain reasonable living standards and afford legal representation while the dissolution proceeds. Temporary maintenance automatically terminates when the final divorce decree is entered, at which point the court may order ongoing maintenance of a different type.
The standard for temporary maintenance focuses on immediate need rather than long-term self-sufficiency. Courts examine the requesting spouse's current monthly expenses, including housing, utilities, food, transportation, health insurance, and attorney fees. The paying spouse's ability to meet these needs while covering their own expenses determines the temporary support amount. Missouri judges typically conduct brief evidentiary hearings on temporary maintenance motions within 30 to 60 days of filing.
Temporary maintenance serves three primary purposes in Missouri dissolution cases. First, it prevents the higher-earning spouse from using financial pressure to force an unfavorable settlement. Second, it allows the dependent spouse to retain qualified legal counsel. Third, it maintains stability for children by preventing sudden disruptions to housing or daily routines. Courts may order temporary maintenance even when the ultimate outcome regarding ongoing support remains uncertain.
Rehabilitative Maintenance
Rehabilitatve maintenance is the most frequently awarded type of alimony in Missouri, designed to support a spouse for a defined period while they acquire education, training, or work experience necessary for self-sufficiency. Missouri courts typically award rehabilitative maintenance for 2 to 5 years, though the duration depends on the specific rehabilitation plan presented. The requesting spouse must demonstrate a concrete plan for achieving financial independence, including educational programs, certification courses, or career development activities.
The court considers several factors when structuring rehabilitative maintenance awards. These include the spouse's prior education level, years out of the workforce, age, health, and the realistic employment opportunities available upon completing rehabilitation. A spouse who left a nursing career 15 years ago to raise children might receive 3 years of rehabilitative maintenance to complete refresher courses and obtain current certifications. The maintenance amount typically covers tuition, books, living expenses, and childcare costs during the rehabilitation period.
Rehabilitave maintenance orders in Missouri may include step-down provisions where monthly payments decrease as the recipient's earning capacity increases. For example, a court might order $2,500 per month for the first 2 years, reducing to $1,500 per month for years 3 and 4 as the recipient enters part-time employment. This graduated approach encourages progress toward self-sufficiency while acknowledging that rehabilitation takes time.
Modifiable Long-Term Maintenance
Modifiable long-term maintenance provides ongoing support without a predetermined end date, subject to modification based on substantial and continuing changes in circumstances under RSMo § 452.370. Missouri courts award modifiable maintenance when the receiving spouse's age, health, or other factors make complete self-sufficiency unlikely. The Missouri Court of Appeals has expressed a judicial preference for open-ended modifiable maintenance over fixed-term awards, particularly in marriages exceeding 15 to 20 years.
The distinguishing feature of modifiable maintenance is its flexibility. Either spouse may petition the court to increase, decrease, extend, or terminate maintenance when circumstances change substantially. Job loss, serious illness, retirement, or significant income changes may justify modification. However, the moving party bears the burden of proving that changed circumstances are both substantial and continuing, not merely temporary fluctuations.
Modifiable maintenance continues until the court orders otherwise, the paying spouse dies, or the receiving spouse remarries. Remarriage automatically terminates modifiable maintenance under Missouri law. Cohabitation does not automatically end payments but may support a modification petition if the new partner substantially subsidizes the recipient's living expenses. Courts examine whether the cohabiting relationship constitutes a substitute for marriage when evaluating modification requests based on cohabitation.
Non-Modifiable Maintenance
Non-modifiable maintenance locks in a specific payment amount and duration that cannot be changed regardless of future circumstances, even substantial income changes for either party. Missouri law permits non-modifiable maintenance only when both parties agree to it in writing, typically as part of a negotiated settlement agreement. Courts cannot impose non-modifiable maintenance over either party's objection following a contested trial.
Parties may choose non-modifiable maintenance for several strategic reasons. The paying spouse gains certainty about their long-term financial obligations and avoids future modification litigation. The receiving spouse gains security knowing payments cannot be reduced even if the paying spouse's income declines or they retire. Non-modifiable maintenance may also facilitate property division negotiations, with one spouse accepting fewer assets in exchange for guaranteed support payments.
However, non-modifiable maintenance carries significant risks. If the receiving spouse's health improves or they secure high-paying employment, the paying spouse cannot seek a reduction. Conversely, if the paying spouse suffers disability or job loss, they remain obligated to pay the full amount. The paying spouse's death terminates non-modifiable maintenance unless the agreement specifically provides otherwise, such as through life insurance requirements. Parties should carefully consider these implications before agreeing to non-modifiable terms.
Permanent Maintenance
Permanent maintenance, while increasingly rare in Missouri, provides indefinite support for spouses who cannot reasonably become self-supporting due to age, disability, or health conditions that developed during a lengthy marriage. Missouri courts typically reserve permanent maintenance for marriages exceeding 20 years where the receiving spouse is over 55 and has limited employment prospects. Unlike modifiable maintenance, permanent maintenance implies an expectation that payments will continue for the recipient's lifetime absent remarriage or death.
The practical difference between modifiable long-term maintenance and permanent maintenance lies primarily in judicial expectations. Both remain subject to modification in theory, but courts evaluating permanent maintenance awards apply a higher threshold for termination. Judges recognize that a 62-year-old spouse who hasn't worked outside the home in 30 years faces different prospects than a 45-year-old completing rehabilitation. Permanent maintenance acknowledges these realities.
Missouri appellate courts have upheld permanent maintenance awards in cases involving spouses with serious health conditions, including chronic illnesses that prevent employment and disabilities that limit earning capacity. The court examines medical evidence, vocational expert testimony, and the marital standard of living when determining whether permanent maintenance is appropriate. Awards typically range from 30% to 50% of the income disparity between spouses, though no formula applies.
Reimbursement Maintenance
Reimbursement maintenance compensates a spouse who financially supported the other's education, professional training, or business development during the marriage with the expectation of sharing in enhanced earning capacity. Missouri courts recognize that one spouse often sacrifices career advancement to fund the other's medical degree, law license, or professional certification. Reimbursement maintenance addresses this contribution even when the supporting spouse can otherwise achieve self-sufficiency.
The calculation of reimbursement maintenance considers direct expenses paid (tuition, books, licensing fees), indirect contributions (household support during training), and opportunity costs (career advancement the supporting spouse forfeited). For example, if one spouse worked two jobs to fund the other's MBA program costing $120,000 over 3 years, reimbursement maintenance might total $150,000 to $180,000, paid over 5 to 10 years following dissolution.
Reimbursement maintenance differs from other types of alimony in Missouri because it focuses on past contributions rather than future needs. A spouse who can otherwise support themselves may still receive reimbursement maintenance to recover their investment in the other spouse's enhanced earning capacity. Courts view this as equitable compensation for marital partnership contributions that would otherwise go unrecognized in property division.
The Eight Statutory Factors Missouri Courts Consider
RSMo § 452.335(2) requires courts to consider all relevant factors when determining maintenance awards, including eight specific considerations that guide judicial discretion. The financial resources of the requesting spouse, including marital property apportioned to them, form the first factor. Courts examine liquid assets, investment accounts, retirement funds, and income-producing property when assessing whether maintenance is necessary.
The time necessary for the requesting spouse to acquire sufficient education or training constitutes the second factor. This directly impacts rehabilitative maintenance duration and amount. Courts consider existing education credentials, work history, age-related learning capacity, and available training programs. A spouse who completed two years of nursing school before marriage faces different rehabilitation needs than someone with no post-secondary education.
The comparative earning capacity of each spouse addresses present and potential future income disparities. Courts examine current employment, salary history, career trajectory, and marketable skills. A 20-year income disparity between a surgeon earning $450,000 and a spouse who worked part-time earning $35,000 creates different maintenance considerations than spouses with similar earning potential who simply chose different career paths.
The standard of living established during the marriage provides a benchmark for reasonable post-divorce needs. Long-term marriages establishing upper-middle-class lifestyles typically justify higher maintenance awards than brief marriages with modest standards. However, courts recognize that maintaining two households costs more than one, and exact duplication of marital lifestyle may be impossible.
The obligations and assets of each party, including marital property apportioned to them, ensure maintenance integrates with property division. A spouse receiving substantial assets generating investment income may need less maintenance than one receiving primarily illiquid property like a residence requiring significant expenses.
The duration of the marriage significantly impacts both maintenance eligibility and duration. Missouri courts rarely award long-term maintenance following marriages under 10 years unless exceptional circumstances exist. Marriages exceeding 20 years create stronger presumptions favoring extended maintenance.
The age and physical and emotional condition of the spouse seeking maintenance affects both employability and reasonable needs. Health insurance costs, medical treatment expenses, and diminished energy for full-time employment factor into maintenance calculations. Mental health conditions may impact the ability to complete rehabilitation programs.
The ability of the paying spouse to meet their own needs while paying maintenance prevents awards that impoverish the obligor. Courts calculate net income after taxes, mandatory deductions, and reasonable living expenses before determining available maintenance funds. Missouri law does not prioritize one spouse's needs over the other's.
Maintenance Duration Guidelines
Missouri has no statutory formula linking maintenance duration to marriage length, though proposed legislation (HB242) would establish specific limits based on marriage duration categories. Under current law, courts exercise complete discretion in setting maintenance terms. However, judicial patterns provide general expectations for how long maintenance typically lasts based on marriage length.
For marriages lasting fewer than 10 years, Missouri courts commonly award rehabilitative maintenance lasting 2 to 4 years. The focus remains on skill development and job placement rather than permanent support. Temporary maintenance during proceedings may extend this period slightly, but long-term maintenance following brief marriages remains exceptional in Missouri.
Moderate-length marriages of 10 to 20 years typically result in maintenance lasting 5 to 10 years, often structured as modifiable awards without firm termination dates. Courts expect these recipients to make progress toward self-sufficiency while acknowledging that career disruptions for childcare and homemaking create lasting employment impacts. Step-down provisions reducing payments over time are common.
Long marriages exceeding 20 years frequently produce open-ended modifiable maintenance extending until retirement age or beyond. Spouses who devoted their primary working years to supporting a family face the steepest employment challenges and often receive the longest maintenance terms. Permanent maintenance remains available for recipients unlikely to achieve meaningful self-sufficiency.
| Marriage Duration | Typical Maintenance Type | Common Duration |
|---|---|---|
| Under 5 years | Rehabilitative | 1-2 years |
| 5-10 years | Rehabilitative/Short-term | 2-4 years |
| 10-15 years | Modifiable | 4-7 years |
| 15-20 years | Modifiable | 6-10 years |
| 20+ years | Long-term/Permanent | Indefinite |
How Maintenance Terminates in Missouri
Maintenance terminates automatically upon the death of either party or the remarriage of the receiving spouse under RSMo § 452.370, unless the parties' written agreement provides otherwise. These automatic termination triggers apply regardless of whether maintenance is modifiable or non-modifiable. The paying spouse has no obligation to notify the receiving spouse of their intent to stop payments upon remarriage; termination occurs by operation of law.
Modifiable maintenance may also terminate when a court grants a modification petition based on substantially changed circumstances. The paying spouse must file a motion demonstrating that changes since the original order make continued payments unreasonable. Job loss alone typically justifies reduction rather than termination, but the receiving spouse's achievement of self-sufficiency through employment, inheritance, or new partnership may support complete termination.
Cohabitation does not automatically terminate Missouri maintenance but may support modification requests. Courts examine whether the receiving spouse's cohabiting relationship has achieved sufficient permanence to constitute a substitute for marriage. Factors include the relationship's duration, shared finances, combined households, and the parties' intentions regarding marriage. A receiving spouse who cohabits with a high-earning partner whose income substantially reduces their reasonable needs may see maintenance terminated based on this changed circumstance.
Tax Implications of Missouri Maintenance
For Missouri divorces finalized after January 1, 2019, spousal maintenance is neither tax-deductible for the paying spouse nor taxable income for the receiving spouse under federal law. The Tax Cuts and Jobs Act of 2017 eliminated the traditional alimony tax treatment that had existed for decades. This change significantly impacts maintenance negotiations and the effective cost of support payments.
Under pre-2019 rules, a paying spouse in the 35% tax bracket who paid $3,000 monthly in maintenance effectively paid only $1,950 after the tax deduction. A receiving spouse in the 15% tax bracket who received $3,000 monthly retained $2,550 after taxes. The combined household kept more money through maintenance payments than through property transfers. This tax arbitrage no longer exists for recent divorces.
Agreements finalized before December 31, 2018, retain the prior tax treatment unless the parties specifically modify their agreement to adopt new rules. Couples with pre-2019 divorce decrees should maintain their existing tax treatment when possible, as it typically benefits both parties. Modifications to pre-2019 agreements may inadvertently trigger the new tax rules, eliminating the paying spouse's deduction.
Filing for Maintenance in Missouri
Spouses seeking maintenance must request it in their dissolution petition or counter-petition filed with the circuit court in the county where either party resides. Missouri requires at least 90 days of residency in the state before the court can grant a divorce, though proceedings may commence earlier. The filing fee ranges from $133 to $225 depending on the county, with additional fees of $25 to $75 for service of process. As of May 2026, verify current fees with your local circuit clerk.
The petition should specify the type of maintenance requested, the monthly amount sought, and the proposed duration. Supporting documentation includes financial declarations, tax returns, pay stubs, and expense statements. Courts require both parties to complete financial disclosure under RSMo § 452.330, exchanging income information, asset inventories, and debt schedules within 30 days of the other party's request.
Missouri imposes a 30-day waiting period after filing before the court may enter a final dissolution judgment. This period allows for negotiation, temporary maintenance motions, and preparation for trial if necessary. Contested maintenance cases typically proceed to trial within 6 to 12 months of filing, though complex cases involving business valuations or disability claims may take longer.
Frequently Asked Questions
What types of alimony are available in Missouri?
Missouri recognizes four primary types of spousal maintenance: temporary (pendente lite) maintenance during divorce proceedings, rehabilitative maintenance for education and training lasting 2 to 5 years, modifiable long-term maintenance without a set end date, and non-modifiable maintenance agreed to by both parties. Courts may also award reimbursement maintenance to compensate for supporting a spouse's education. Each type addresses different circumstances and needs following dissolution of marriage.
How do Missouri courts calculate maintenance amounts?
Missouri has no statutory formula for calculating maintenance amounts, giving courts broad discretion under RSMo § 452.335. Judges consider eight factors including each spouse's financial resources, earning capacity, marital standard of living, and marriage duration. A common informal guideline suggests 30% to 35% of the income difference between spouses, but actual awards vary significantly based on individual circumstances and judicial discretion.
Can maintenance be modified after the divorce is final?
Modifiable maintenance orders may be increased, decreased, extended, or terminated based on substantial and continuing changes in circumstances under RSMo § 452.370. Job loss, significant income changes, serious illness, or the receiving spouse's improved financial situation may justify modification. Non-modifiable maintenance agreed to by both parties cannot be changed regardless of circumstances, even if the paying spouse loses their job or becomes disabled.
Does remarriage affect spousal maintenance in Missouri?
Remarriage by the receiving spouse automatically terminates maintenance under Missouri law, effective immediately upon the new marriage. The paying spouse may stop payments without court intervention once remarriage occurs. However, the paying spouse's remarriage has no direct effect on their maintenance obligations, though their new household expenses may factor into modification requests.
How does cohabitation affect Missouri maintenance?
Cohabitation does not automatically terminate maintenance in Missouri, unlike remarriage. However, if the receiving spouse lives with a partner whose income substantially reduces their reasonable needs, the paying spouse may petition for modification under RSMo § 452.370. Courts examine whether the relationship constitutes a substitute for marriage, considering relationship duration, shared finances, and the parties' intentions.
What is the difference between modifiable and non-modifiable maintenance?
Modifiable maintenance can be changed by court order when circumstances substantially change, while non-modifiable maintenance remains fixed regardless of future events. Courts must specify which type they are ordering under RSMo § 452.335(3). Non-modifiable maintenance requires agreement by both parties and cannot be imposed over either party's objection. If the paying spouse loses income or the receiving spouse gains employment, non-modifiable maintenance continues unchanged.
Is maintenance taxable in Missouri?
For divorces finalized after January 1, 2019, maintenance is not tax-deductible for the paying spouse and not taxable income for the receiving spouse under federal law. The Tax Cuts and Jobs Act eliminated the traditional alimony tax treatment. Missouri follows federal tax treatment, so state income tax consequences mirror the federal rules. Pre-2019 divorces retain the prior tax treatment unless specifically modified.
How long do I have to be married to get maintenance in Missouri?
Missouri has no minimum marriage duration requirement for maintenance eligibility. However, marriage length significantly affects both the likelihood and duration of awards. Marriages under 5 years rarely result in long-term maintenance. Marriages of 10 to 20 years typically produce rehabilitative or mid-term modifiable maintenance. Marriages exceeding 20 years frequently result in long-term or permanent maintenance, particularly when one spouse sacrificed career development.
Can I get temporary maintenance while my divorce is pending?
Yes, Missouri courts may award temporary (pendente lite) maintenance to either spouse during divorce proceedings. Temporary maintenance helps the dependent spouse cover living expenses and attorney fees while the case proceeds. Courts typically hear temporary maintenance motions within 30 to 60 days of filing. Temporary maintenance ends automatically when the final divorce decree is entered, at which point ongoing maintenance may be ordered.
What happens to maintenance if my ex-spouse dies?
Maintenance terminates automatically upon the death of either party under Missouri law. The paying spouse's estate has no ongoing maintenance obligation unless the divorce agreement specifically provides otherwise. Receiving spouses concerned about this possibility may negotiate for life insurance requirements or present-value lump-sum settlements instead of ongoing payments. The receiving spouse's death obviously ends their need for support payments.
