Louisiana does not use a fixed formula to calculate alimony. Under Louisiana Civil Code Article 112, courts award final periodic spousal support based on nine statutory factors, including income, earning capacity, and the duration of the marriage. Louisiana law caps final spousal support at one-third of the paying spouse's net income in most cases. An alimony calculator for Louisiana can help you estimate a likely range, but only a court can set the final amount.

How Does an Alimony Calculator Work in Louisiana?
A Louisiana alimony calculator estimates spousal support by analyzing each spouse's gross and net income, the length of the marriage, and the statutory cap of one-third of the payor's net income under La. Civ. Code Art. 112. Louisiana does not use a mathematical formula like child support guidelines, so any calculator provides an estimate rather than a guaranteed outcome. Courts retain broad discretion to set the final amount.
To use a spousal support calculator for Louisiana, you generally need to input each spouse's monthly net income, the number of years married, and whether minor children are involved. The calculator then applies the one-third cap rule as a baseline. For example, if the higher-earning spouse has a net monthly income of $9,000, the statutory maximum for final periodic support would be $3,000 per month. The actual award may be lower depending on the requesting spouse's demonstrated need and the nine factors listed in Article 112(B).
Louisiana courts distinguish between two types of spousal support: interim support under Article 113 and final periodic support under Article 112. An alimony estimator must account for both types because they use different standards. Interim support focuses on maintaining the marital standard of living, while final support addresses the claimant's demonstrated need and the payor's ability to pay.
What Are the Two Types of Spousal Support in Louisiana?
Louisiana recognizes two types of spousal support: interim spousal support and final periodic support. Interim support under La. Civ. Code Art. 113 maintains the marital standard of living during the divorce process and terminates 180 days after the divorce judgment. Final periodic support under La. Civ. Code Art. 112 addresses long-term need and is capped at one-third of the payor's net income.
Interim spousal support is available to either spouse during the divorce proceedings regardless of fault. The court considers four factors when awarding interim support: (1) the needs of the requesting party, (2) the ability of the other party to pay, (3) any interim or final child support obligation, and (4) the standard of living during the marriage. Interim support can extend beyond the 180-day post-judgment period only when the requesting spouse demonstrates good cause.
Final periodic support carries a stricter threshold. The requesting spouse must prove two requirements: that they are free from fault prior to filing for divorce, and that they are in need of support. Louisiana law defines fault broadly to include adultery, habitual intemperance, cruel treatment, and abandonment. If a spouse committed any of these acts before the divorce petition was filed, that spouse is generally disqualified from receiving final periodic support under Article 112(A).
| Feature | Interim Support (Art. 113) | Final Support (Art. 112) |
|---|---|---|
| Fault Requirement | No fault requirement | Claimant must be fault-free |
| Standard | Marital standard of living | Need-based |
| Duration | 180 days post-judgment (extendable) | Court discretion; no statutory maximum |
| Income Cap | No statutory cap | One-third of payor's net income |
| Factors Considered | 4 factors | 9 factors |
| When Available | During divorce proceedings | After divorce is final |
What Are the Nine Factors Courts Use to Calculate Alimony in Louisiana?
Louisiana courts evaluate nine statutory factors under La. Civ. Code Art. 112(B) when determining the amount and duration of final periodic spousal support. These factors give judges broad discretion, which is why no alimony calculator for Louisiana can produce an exact figure. Each factor is weighed based on the specific circumstances of the case.
The nine factors are:
- The income and means of the parties, including the liquidity of such means
- The financial obligations of the parties, including any interim allowance or final child support obligation
- The earning capacity of the parties
- The effect of custody of children upon a party's earning capacity
- The time necessary for the claimant to acquire appropriate education, training, or employment
- The health and age of the parties
- The duration of the marriage
- The tax consequences to either or both parties
- The existence, effect, and duration of any act of domestic abuse committed by the other spouse upon the claimant or a child of one of the spouses, regardless of whether the other spouse was prosecuted for the act of domestic violence
Factor 7 carries significant weight in Louisiana courts. Marriages lasting 20 years or more typically result in longer spousal support awards than marriages lasting fewer than 10 years. Factor 9 creates a special presumption: when domestic abuse is established, the victimized spouse is presumed entitled to final periodic support, and the one-third income cap may be exceeded at the court's discretion.
How Is the One-Third Cap on Spousal Support Applied?
Louisiana law limits final periodic spousal support to no more than one-third (33.3%) of the paying spouse's net income under La. Civ. Code Art. 112. This cap applies to final support only and does not restrict interim spousal support awards under Article 113. The one-third cap is the single most important variable in any Louisiana spousal support calculator.
Net income for purposes of the one-third cap includes all sources of income minus mandatory deductions such as federal and state taxes, Social Security contributions, and Medicare withholdings. Voluntary deductions such as retirement contributions and health insurance premiums may or may not be included depending on the court's analysis. For a payor earning $120,000 per year in net income, the maximum annual final spousal support award would be $40,000, or approximately $3,333 per month.
The one-third cap has two notable exceptions. First, when the court determines that the paying spouse committed domestic abuse during the marriage, the court may exceed the one-third limit. Second, if the spouses agree to a different amount in a settlement or consent judgment, the one-third cap does not apply because the parties have voluntarily waived the statutory protection. Louisiana courts have upheld contractual spousal support provisions in excess of one-third when both parties consented.
How Long Does Spousal Support Last in Louisiana?
Louisiana does not impose a statutory maximum duration for final periodic spousal support, giving courts broad discretion to set the length of the obligation under La. Civ. Code Art. 112. Interim support terminates automatically 180 days after the divorce judgment under Article 113, with extensions available only upon a showing of good cause. Duration is one of the most difficult variables for any alimony estimator to predict.
Louisiana courts generally consider the length of the marriage as the primary factor in setting duration. For marriages lasting fewer than 10 years, courts frequently limit final support to a rehabilitative period of 1 to 3 years, allowing the requesting spouse time to gain education or employment. For marriages lasting 10 to 20 years, support periods of 3 to 7 years are common. For marriages exceeding 20 years, courts may award support for significantly longer periods, particularly when the requesting spouse sacrificed career development during the marriage.
Final periodic spousal support terminates automatically under La. Civ. Code Art. 115 upon the remarriage of the receiving spouse, the death of either party, or a judicial determination that the receiving spouse has cohabited with another person in the manner of married persons. Either party may also petition for modification under La. Civ. Code Art. 116 upon showing a material change in circumstances, such as a substantial increase or decrease in either party's income.
What Is the Fault Requirement for Spousal Support in Louisiana?
Louisiana requires the spouse requesting final periodic support to be free from fault prior to filing for divorce under La. Civ. Code Art. 112(A). This fault-free requirement is unique among U.S. states and eliminates approximately 15-20% of potential spousal support claims. No alimony calculator can account for fault determinations, which require case-specific legal analysis.
Fault in Louisiana spousal support law includes adultery, conviction of a felony with a sentence of imprisonment at death or hard labor, habitual intemperance or excesses, cruel treatment, public defamation, abandonment, and an attempt on the other spouse's life. The critical time frame is conduct occurring before the filing of the divorce petition. Conduct after filing generally does not bar a claim for final periodic support.
The fault-free requirement does not apply to interim spousal support under Article 113. A spouse who committed marital fault may still receive interim support during the divorce proceedings to maintain the marital standard of living. However, that same spouse would be barred from receiving final periodic support once the divorce is granted. Louisiana courts analyze fault claims case by case, and the burden of proving fault rests on the spouse opposing the support claim.
How Do You File for Spousal Support in Louisiana?
Filing for spousal support in Louisiana requires domicile in the state for at least 6 months and filing in the parish where either spouse is domiciled or the last matrimonial domicile under La. Code Civ. Proc. Art. 3941. Filing fees range from $200 to $400 or more depending on the parish, with an additional $50 to $100 for service of process. As of March 2026, verify current fees with your local parish clerk of court.
The filing process follows these steps:
- File a Petition for Divorce in the appropriate parish court, including a request for interim and/or final spousal support
- Serve the petition on the other spouse through the sheriff's office or a private process server ($50-$100)
- File a Rule to Show Cause or Motion for Interim Spousal Support to request temporary support during the divorce
- Exchange financial documents including tax returns, pay stubs, bank statements, and a Detailed Descriptive List of assets and liabilities
- Attend a hearing where the court evaluates the Article 112 or Article 113 factors
- Receive a court order specifying the amount and duration of the support obligation
Louisiana offers two paths to no-fault divorce. Under Article 102, a spouse files the petition before the separation period is complete, and the 180-day or 365-day clock begins at service. Under Article 103, a spouse files after the separation period has already elapsed, allowing for a faster resolution. The choice between Article 102 and Article 103 affects the timeline for requesting spousal support.
How Does Community Property Affect Spousal Support in Louisiana?
Louisiana is 1 of 9 community property states in the United States, meaning all assets and debts acquired during the marriage are presumed to belong equally to both spouses under La. Civ. Code Art. 2338. The community property division directly affects spousal support calculations because a spouse who receives a larger share of community assets may have a reduced need for ongoing support.
When using a spousal support calculator for Louisiana, the community property split is a critical input. If one spouse receives $500,000 in community assets including the family home, retirement accounts, and investment portfolios, that spouse's demonstrated need for monthly support payments may be significantly reduced. Louisiana courts consider the income-generating potential of distributed assets when evaluating the income and means factor under Article 112(B)(1).
Louisiana also recognizes separate property, which includes assets owned before the marriage, inheritances, and gifts received by one spouse during the marriage under La. Civ. Code Art. 2341. Separate property is not divided in a divorce but is considered when evaluating the overall financial picture for spousal support purposes. A spouse with substantial separate property assets may face a reduced spousal support claim because the requesting spouse must demonstrate actual need.
What Is the Average Cost of a Divorce Involving Spousal Support in Louisiana?
A Louisiana divorce involving spousal support typically costs between $10,000 and $30,000 in attorney fees and court costs when contested, compared to $1,500 to $5,000 for an uncontested divorce with no spousal support dispute. Filing fees range from $200 to $400 depending on the parish, with additional costs for service of process, discovery, expert witnesses, and hearing fees. As of March 2026, verify filing fees with your local parish clerk.
| Cost Component | Uncontested | Contested |
|---|---|---|
| Filing Fee | $200-$400 | $200-$400 |
| Service of Process | $50-$100 | $50-$100 |
| Attorney Fees | $1,000-$3,000 | $7,500-$25,000+ |
| Financial Expert/CPA | $0 | $2,000-$5,000 |
| Mediation | $500-$2,000 | $1,000-$3,000 |
| Total Estimated Cost | $1,500-$5,000 | $10,000-$30,000+ |
Louisiana law allows fee waivers for parties whose household income falls at or below 125% of the federal poverty guidelines. Courts may also order one spouse to contribute to the other spouse's attorney fees under La. Code Civ. Proc. Art. 3945 when there is a significant disparity in financial resources. Fee-shifting requests are evaluated on a case-by-case basis and are not automatically granted.
Can Spousal Support Be Modified or Terminated in Louisiana?
Final periodic spousal support can be modified or terminated upon a showing of a material change in circumstances under La. Civ. Code Art. 116. Automatic termination occurs upon the remarriage of the receiving spouse, the death of either party, or cohabitation by the receiving spouse with another person in the manner of married persons under La. Civ. Code Art. 115. Modification requires a separate court petition and hearing.
Common grounds for modification include a substantial increase or decrease in either party's income, the receiving spouse obtaining employment or completing education, a change in health status, retirement of the paying spouse, or a significant change in the cost of living. Louisiana courts require the change to be material and involuntary. A payor who voluntarily quits a job or reduces income to avoid support obligations will not receive a favorable modification ruling.
Louisiana also recognizes a peremptive period for seeking final periodic support. Under La. Civ. Code Art. 117, a claim for final spousal support is subject to a peremptive period of 3 years from the date of the divorce judgment. If the requesting spouse does not file for final support within 3 years of the divorce, the right to seek support is permanently extinguished. This 3-year deadline is one of the most critical timelines in Louisiana spousal support law.
Frequently Asked Questions About Alimony in Louisiana
Is there a formula for calculating alimony in Louisiana?
Louisiana does not use a mathematical formula to calculate alimony. Under La. Civ. Code Art. 112(B), courts evaluate nine statutory factors and apply judicial discretion to set the amount. The only fixed guideline is the one-third cap on the payor's net income. An alimony calculator for Louisiana provides estimates based on this cap and income inputs.
How much alimony can I expect to receive in Louisiana?
The maximum final periodic spousal support in Louisiana is one-third (33.3%) of the paying spouse's net income under La. Civ. Code Art. 112. For a payor with $6,000 in monthly net income, the maximum award is $2,000 per month. Actual awards depend on demonstrated need, and many awards fall below the statutory cap.
Does adultery affect alimony in Louisiana?
Adultery committed before filing for divorce bars the unfaithful spouse from receiving final periodic support under La. Civ. Code Art. 112(A). Louisiana is one of the few states where marital fault directly eliminates eligibility for long-term spousal support. The faithful spouse bears the burden of proving the adultery occurred before the petition was filed.
How long do I have to be married to get alimony in Louisiana?
Louisiana does not set a minimum marriage duration for spousal support eligibility. However, the duration of the marriage is one of nine factors under La. Civ. Code Art. 112(B)(7). Marriages lasting fewer than 5 years rarely result in extended support awards, while marriages exceeding 20 years are more likely to produce longer-term obligations.
Can spousal support be waived in a prenuptial agreement in Louisiana?
Louisiana law permits spouses to waive final periodic spousal support in a prenuptial or postnuptial agreement under La. R.S. 9:2332. The waiver must be in writing, signed by both parties, and executed with the formalities required for matrimonial agreements. Courts may refuse to enforce a waiver that would leave one spouse destitute.
Does cohabitation terminate spousal support in Louisiana?
Cohabitation with another person in the manner of married persons automatically terminates final periodic spousal support under La. Civ. Code Art. 115. The paying spouse must file a motion to terminate and prove the cohabitation. Louisiana courts examine factors such as shared residence, shared expenses, and the duration of the relationship to determine whether cohabitation exists.
Can I receive spousal support during the divorce process?
Interim spousal support is available during the divorce proceedings under La. Civ. Code Art. 113, regardless of fault. Interim support is based on the marital standard of living and terminates 180 days after the divorce judgment. Courts may extend interim support beyond 180 days for good cause, such as a pending final support hearing.
Is spousal support taxable in Louisiana?
Under the Tax Cuts and Jobs Act of 2017, spousal support payments made under divorce agreements executed after December 31, 2018 are not tax-deductible for the payor and not taxable income for the recipient. For agreements executed before January 1, 2019, the pre-TCJA rules apply: the payor deducts payments and the recipient reports them as income. Louisiana courts consider tax consequences as factor 8 under La. Civ. Code Art. 112(B)(8).
What happens if my ex-spouse stops paying alimony?
Louisiana courts enforce spousal support orders through contempt of court proceedings, income assignment orders, and wage garnishment. Under La. R.S. 9:315.30, courts may issue an income assignment order directing the payor's employer to withhold support from wages. A spouse found in contempt of a support order may face fines, attorney fee awards, and incarceration.
Can I get alimony if I was the higher earner during the marriage?
Yes, Louisiana spousal support is gender-neutral and available to either spouse regardless of who earned more during the marriage. Under La. Civ. Code Art. 112, the court evaluates need and ability to pay based on current circumstances. If the higher-earning spouse experiences job loss, disability, or other financial hardship after separation, that spouse may qualify for final periodic support if they meet the fault-free requirement.
