Louisiana runs on a different legal foundation than the rest of the country — it's the only state built on civil law instead of English common law, and that shapes divorce finances here too. Louisiana is a community property state, meaning property acquired during the marriage is generally treated as owned equally by both spouses. But Louisiana adds a wrinkle most community property states don't have: the community property clock stops on the date one spouse files for divorce, not the date the divorce is finalized. That single rule can meaningfully change what counts as shared property in a case that takes months to resolve.

Property Division: Community Property, With a Filing-Date Cutoff

Louisiana divides marital property under Louisiana Civil Code Article 2336 and Article 2338. Community property means each spouse owns an undivided one-half interest in property acquired during the marriage through either spouse's effort, skill, or industry — it doesn't matter whose name is on the paycheck, the house, or the bank account. Property owned before the marriage, along with inheritances and gifts received individually during the marriage, is generally separate property that stays with the spouse who owns it, as long as it isn't mixed together with community funds.

Here's where Louisiana differs from almost every other community property state: the community property regime doesn't end on the day the divorce is finalized. Under Louisiana Civil Code Article 159, it terminates retroactively to the date one spouse files the petition for divorce. Income earned and property acquired after that filing date generally belongs separately to the spouse who earned or acquired it, even though the case itself might not wrap up for months. Most community property states — California, Texas, Nevada, and others — instead use the date of separation or the date of the final judgment, so this filing-date rule is a real distinction worth understanding whether you're the spouse filing or the spouse being served.

Filing date matters more in Louisiana than in most states. Because the community property clock stops the day the petition is filed, the timing of that filing can affect which income and assets count as shared. This is a detail worth raising early with a Louisiana family law attorney, especially if there's a significant gap between filing and finalizing.
Hypothetical Example — Property Division

Suppose a couple has been married 12 years and one spouse files for divorce in March. Over the following eight months before the divorce is finalized, the filing spouse earns $60,000 in salary and the other spouse earns $45,000. Under Louisiana's filing-date rule, that $105,000 in combined post-filing income generally stays separate — it isn't added to the community property that gets divided. The house purchased in year three of the marriage, the retirement contributions made before filing, and the joint savings built up over 12 years remain community property, generally split with each spouse owning an undivided one-half share. This example is illustrative only — how specific assets and income streams are classified can turn on the facts of each case.

Alimony: Interim Support, Final Support, and a Fault Bar

Louisiana recognizes two distinct types of spousal support. Interim spousal support, available under Civil Code Article 113, can be awarded while the divorce case is still pending. It's meant to help a spouse maintain something close to the standard of living from the marriage until the case resolves, and it doesn't require the requesting spouse to be free of fault. Final periodic support, awarded under Article 112 after the divorce is finalized, works differently — it's based on demonstrated need, and it generally requires the requesting spouse to not be legally at fault in causing the marriage's breakup.

Final periodic support is calculated by weighing nine statutory factors: the needs of both parties, their incomes and financial obligations, each spouse's earning capacity, the duration of the marriage, the age and health of each party, the tax consequences of a support award, how child custody affects a spouse's earning capacity, each spouse's separate property, and any other relevant circumstances. There's no formula that produces a specific number — courts weigh all nine factors against the facts of the case.

Final periodic support is generally capped at one-third of the payor's net income. Under Article 112, the total amount awarded generally cannot exceed one-third of the paying spouse's net income — income after taxes and mandatory deductions. This cap can be exceeded in cases involving documented domestic abuse, or when the divorce was granted on certain fault-based grounds. Interim spousal support, which applies while the case is pending, is not subject to this same cap.
Fault can eliminate a final support claim entirely. Legal fault in Louisiana generally includes things like adultery, habitual intemperance, cruel treatment, abandonment, or conviction of a felony. A spouse found legally at fault in causing the marriage's breakup is generally barred from receiving final periodic support, regardless of financial need. This is a meaningfully different standard from interim support, which is available while the case is pending without a fault showing.
Hypothetical Example — Final Periodic Support

Suppose Spouse A earns $8,000/month net and Spouse B earns $2,000/month net after a 20-year marriage, and neither spouse is found to be at fault. Weighing the nine statutory factors — the length of the marriage, the income gap, and Spouse B's reduced earning capacity after years focused on the household — a court might consider a final periodic support award, though the total can't exceed one-third of Spouse A's net income, or roughly $2,640/month in this example. If Spouse B were instead found legally at fault for the marriage's breakup — proven adultery, for instance — Spouse B would generally be barred from receiving final periodic support at all, regardless of the income gap. This is an estimate only; actual outcomes vary by case.

Child Support: Income Shares Model

Louisiana calculates child support using the Income Shares Model under La. Rev. Stat. § 9:315 et seq., with the actual guideline numbers set out in § 9:315.19. The idea behind the model is to estimate what the child would have received if the parents' household hadn't split. Courts add both parents' adjusted gross monthly incomes together, look up the combined figure on the statutory schedule, and split the resulting basic support obligation proportionally based on each parent's share of the combined income.

The schedule starts at a minimum basic obligation of $100 per month for one child at the lowest income bracket and scales up from there based on income and the number of children. It runs up to a combined monthly adjusted gross income cap of $40,000 — above that level, courts have more discretion in setting an appropriate amount rather than following the table directly.

Add-on costs are layered on top of the basic obligation. The basic child support obligation from the schedule isn't the whole picture. Louisiana courts generally add in costs like work-related childcare and the child's health insurance premium, then split those add-on costs proportionally between the parents based on income share, on top of the base amount.
Hypothetical Example — Child Support Estimate

Suppose Parent A has an adjusted gross income of $5,500/month and Parent B has $2,500/month, for a combined income of $8,000. For one child, the statutory schedule at that combined income level might set the basic obligation around $1,000/month. Parent A earns roughly 69% of the combined income and Parent B roughly 31%, so Parent A's share of the obligation would be about $690/month and Parent B's about $310/month. If the child lives primarily with Parent B, Parent A would generally pay their share to Parent B, with childcare and health insurance costs layered on top and split the same way. These numbers are illustrative — the Louisiana Department of Children & Family Services calculator or a family law attorney can generate a figure based on current numbers.

Retirement Accounts: Community Property and QDROs

Retirement contributions made during the marriage are community property in Louisiana, owned in an undivided one-half share by each spouse, while contributions made before the marriage or after the community property regime terminates — remember, that's the filing date, not the divorce date — are generally separate property. Courts typically use a coverture fraction, the portion of time the retirement plan was funded during the marriage divided by the total time the plan has been funded, to identify the community share of the account.

Dividing a 401(k), 403(b), or private-sector pension generally requires a Qualified Domestic Relations Order (QDRO) — a separate court order directing the plan administrator to divide the account. A properly executed QDRO allows the transfer to happen without triggering early withdrawal penalties or income taxes at the time of transfer.

Louisiana's state and local government retirement systems — including the Louisiana State Employees' Retirement System (LASERS) and the Teachers' Retirement System of Louisiana (TRSL) — are not divided using a standard federal QDRO. These systems have their own community property division procedures, and the process for splitting a state pension differs from dividing a private-sector 401(k). If either spouse works in state government, public education, or another role covered by LASERS or TRSL, confirming the exact procedure with the plan matters.

Military and federal retirement. Louisiana has a significant military population, including bases like Fort Johnson and Barksdale Air Force Base. Military pensions are divided under the federal Uniformed Services Former Spouses' Protection Act (USFSPA), and Federal Thrift Savings Plan (TSP) accounts use a "Retirement Benefits Court Order" rather than a standard QDRO.

Divorce Timeline: Louisiana's Separation Requirement

Most Louisiana divorces are filed as no-fault under Civil Code Articles 102 and 103, which require spouses to live separate and apart for a set period before the divorce can be finalized. Under Article 103.1, that period is 180 days for couples with no minor children of the marriage, and 365 days for couples who have minor children together. Once the required separation period has passed, an Article 103 divorce can generally move through the court relatively quickly, since the waiting period has already been satisfied before filing.

Louisiana also permits fault-based divorce under Article 103, filed on grounds like adultery or a felony conviction, which can bypass the separation-period requirement — but proving fault-based grounds generally requires more evidence and a longer contested process. And unlike most states, Louisiana offers an optional "covenant marriage" — a stricter marriage contract some couples choose at the outset that imposes additional requirements, including counseling and longer separation periods, before a divorce can be granted.

The separation period runs before you file, not after. Because Article 103 divorces require the separation period to have already passed, couples who have been living apart for six months or a year — depending on whether they have minor children — before filing may find the process moves faster than in states where the waiting period starts at filing.
