Spousal support in Louisiana is determined by a statutory multi-factor analysis under La. Civ. Code art. 111–113. The court weighs the following factors to arrive at a fair support amount and duration. Unlike the temporary formula, there is no mathematical calculation for permanent support — it is a discretionary determination by the judge based on the totality of the circumstances.
The types of spousal support available in Louisiana include: Interim periodic support (during proceedings), Final periodic support (post-divorce, limited duration). The type ordered depends on the length of the marriage, each spouse's financial situation, and the supported spouse's ability to become self-supporting.
Primary statute: La. Civ. Code art. 111–113
The court considers these 8 statutory factors when determining the amount and duration of spousal support:
Income and means of the parties
Financial obligations of the parties
Earning capacity of the parties
Effect of custody of children on earning capacity
Time necessary for education or training for adequate employment
Health and age of the parties
Duration of the marriage
Tax consequences to either party
Final periodic support: limited to the lesser of 1/3 of the marriage length or specific finding of need. Court cannot award permanent alimony.
Duration is one of the most heavily litigated aspects of spousal support. The length of the marriage is the single most important factor in most cases, but the court also considers the supported spouse's age, health, job skills, and the time needed to acquire education or training for appropriate employment.
Louisiana limits final periodic support duration — cannot exceed 1/3 of the marriage length (general guideline).
Fault (adultery, abuse) can bar alimony under La. Civ. Code art. 112(B).
Interim support is available during proceedings; final support is post-divorce.
