How Louisiana child support is calculated

Louisiana uses a shared income model to calculate child support. First, the combined gross income of both parents is determined. Then, this is adjusted by subtracting pre-existing child support or spousal support obligations to arrive at the combined adjusted gross income. Using a statutory schedule based on the combined adjusted gross income and the number of children, a basic child support obligation is found. Additional expenses such as work-related childcare costs, health insurance premiums, and extraordinary medical expenses are added to this basic obligation. Finally, the total child support obligation is divided between the parents proportionally, based on each parent's share of the combined adjusted gross income.

What can change your child support amount

Income changes

A substantial change in either parent's income — voluntary or involuntary — can trigger a modification.

Childcare & insurance

Changes in childcare costs or the children's health insurance premiums directly adjust the support amount.

Parenting time shifts

If the custody schedule changes significantly, support can be recalculated under Louisiana guidelines.

Child's special needs

Medical conditions, disabilities, or educational needs can justify a departure from the guideline amount.

Common questions

What people ask about child support

How long does a divorce take in Louisiana?

A divorce in Louisiana can take 180 days if there are minor children, or 365 days if there are no minor children, after the petition is filed and served. This is the mandatory waiting period before the divorce can be finalized.

Do I need a lawyer to get divorced in Louisiana?

While it is not legally required to have a lawyer for a divorce in Louisiana, it is highly recommended, especially if there are complex issues involving property division, child custody, or support. A lawyer can ensure your rights are protected and all legal requirements are met.

Is Louisiana a no-fault divorce state?

Yes, Louisiana is a no-fault divorce state. A divorce can be granted based on "irreconcilable differences" without needing to prove fault. The primary requirement is living separate and apart for a specified period (180 or 365 days).

How is property divided in Louisiana divorce?

Louisiana is a community property state. This means that assets and debts acquired during the marriage are generally considered community property and are subject to a 50/50 split between the spouses, unless otherwise agreed upon or ordered by the court.

What is the difference between a fault and no-fault divorce in Louisiana?

In Louisiana, a no-fault divorce is granted based on the spouses living separate and apart for a specified period (180 or 365 days) due to irreconcilable differences. A fault-based divorce, while less common now, would require proving specific grounds like adultery or abuse, which can impact alimony or property division in some cases.
