Louisiana Child Support: A Parent's Guide

Q: How is child support calculated in Louisiana?

Using the Income Shares approach under R.S. 9:315: the court determines each parent's gross income, calculates the combined adjusted gross income, and references the Child Support Schedule (R.S. 9:315.19) to find the basic support obligation, allocated proportionally by each parent's share of income.

Q: What foundational principles guide Louisiana's guidelines?

Child support is a continuous obligation of both parents, children are entitled to share in the current income of both parents, and children shouldn't be the economic victims of divorce or an out-of-wedlock birth, the same premises that underlie income shares models generally.

Q: How does the schedule account for Louisiana's economics?

The schedule uses national average economic data, adjusted to reflect Louisiana's status as a lower-income state, and incorporates a self-sufficiency reserve to protect low-income paying parents.

Q: How do I request a modification in Louisiana?

File a petition with the court that issued the original order. A support order can't be modified unless the party seeking the change shows a material change in circumstances since the order was granted. You can also submit a Request for Review through DCFS, or file directly using the SES 668 Rule to Modify Child Support form.

In short: Louisiana uses the Income Shares model, with a schedule specifically adjusted to reflect the state's status as a lower-income state and built-in protection for low-income paying parents. Automatic wage withholding applies to every court-issued support order, and modification requires a material change in circumstances filed with the original issuing court, or a request through DCFS.

What Louisiana generally provides

Under La. R.S. § 9:315, Louisiana's Income Shares guidelines rest on three premises: child support is a continuous obligation of both parents, children are entitled to share in the current income of both parents, and children shouldn't be the economic victims of divorce or an out-of-wedlock birth. The court determines each parent's gross income, calculates the combined adjusted gross income, and references the Child Support Schedule (R.S. 9:315.19).

Important terminology

Child Support Schedule: Louisiana's statutory guideline table under R.S. 9:315.19, built from national economic data adjusted for the state's lower cost/income profile.
Self-sufficiency reserve: a built-in protection for low-income paying parents within the schedule's design.
DCFS: the Louisiana Department of Children & Family Services, which handles many modification requests and enforcement.

How the calculation works

Income pooling as a design principle

In intact families, the income of both parents is pooled and spent for the benefit of all household members, including the children. Louisiana's guidelines apply this same income-sharing principle to determine how the parents will share a support award after separation, each parent's contribution to the combined income reflects their relative share of household expenses.

A schedule adjusted for Louisiana's economics

The schedule uses a table of national averages, specifically adjusted to reflect Louisiana's status as a lower-income state, and incorporates a self-sufficiency reserve for low-income paying parents, a distinctive built-in adjustment not every state's schedule includes explicitly.

Combining and allocating

The court determines each parent's gross income, calculates the combined adjusted gross income, references the Child Support Schedule to find the basic obligation for the number of children, then allocates that amount proportionally based on each parent's share of the combined income.

Requesting or defending a modification

A support order can't be modified unless the requesting party shows a material change in circumstances since the order was granted. You can file a petition with the court that issued the original order, submit a Request for Review through DCFS by calling 1-877-752-3237 or the CAFÉ Self Service Portal, or file directly with the clerk of court using the SES 668 Rule to Modify Child Support form. See the child support calculator and guideline finder for jurisdiction-specific calculation sources and guidance.

How enforcement works

Louisiana requires automatic wage withholding whenever a court issues a child support order, payments are deducted from the paying parent's income before they receive it, no separate delinquency required to trigger it. The Income Withholding Order/Notice for Support (IWO) is the standardized form used, and all employers must honor it. Louisiana's exemption from seizure of disposable earnings for current or past-due child support is 50% of disposable earnings, the cap on how much can be withheld.

Common questions

Does withholding only start if I fall behind? No, Louisiana's automatic wage withholding attaches to the order itself from the start, it isn't conditioned on missing a payment first.

How much protection does the schedule build in for lower-income parents? The schedule includes a self-sufficiency reserve specifically designed to avoid setting an unworkable obligation for low-income paying parents, part of how the state adjusted the national data for its own economic profile.

Practical considerations

Because Louisiana's schedule was specifically built around the state's lower-income economic profile, don't assume figures from a national or another state's calculator translate directly, use Louisiana's own schedule or DCFS resources for an accurate estimate.
