How to run Alimony Child Support in DocketMath for Louisiana

Step-by-step

This guide walks you through running Alimony + Child Support calculations in DocketMath for Louisiana using jurisdiction-aware rules. You’ll use one calculator (alimony-child-support) and select US-LA so DocketMath applies Louisiana’s governing frameworks.

• Child support: calculated using the Louisiana Child Support Schedule under La. R.S. § 9:315.19 (part of La. R.S. § 9:315 et seq.)
• Spousal support (alimony): governed by La. Civ. Code arts. 111–117

  • Final periodic spousal support: La. Civ. Code art. 111 (freedom-from-fault threshold concept)
  • Interim spousal support: La. Civ. Code arts. 113–115

Important note (tool default): Since no claim-type-specific sub-rule was found for this tool’s setup, the calculator uses the general/default “period” approach for the combined run. You should still choose the correct interim vs final periodic spousal timing option because that changes which Civil Code article set is reflected.

1) Start the calculator and select Louisiana (US-LA)

1. Open the tool: /tools/alimony-child-support
2. Choose jurisdiction: US-LA (Louisiana)
3. Confirm the calculator mode is set for alimony + child support (the default general approach is used here, per the note above).

2) Enter parent income inputs (drives both child and spousal support)

DocketMath will typically ask for income information for:

• Parent A gross monthly income
• Parent B gross monthly income

If the tool provides additional income fields (for example, overtime, bonuses, or other adjustments), enter them in the locations DocketMath provides.

How outputs change (practical expectation):

• Child support will change substantially when incomes change because Louisiana uses an income-shares schedule at La. R.S. § 9:315.19.
• Spousal support estimates will also be income-sensitive under La. Civ. Code arts. 111–117, including the interim framework in arts. 113–115.

3) Add children and custody/parenting-time inputs (for child support)

To calculate Louisiana child support under La. R.S. § 9:315.19, you’ll also need the calculator’s child-related inputs, usually including:

• Number of children
• A parenting time / custody allocation input (how parenting time is divided)

Because Louisiana’s schedule is built around the shared cost of children, parenting-time inputs meaningfully affect the result.

Checklist for this step:

• Number of children entered correctly
• Parenting-time/custody allocation entered in the same units DocketMath expects
• Any special flags (if your tool shows them) are selected consistently with your case facts

4) Choose spousal-support timing: interim vs final periodic

Louisiana spousal support is handled differently depending on whether it’s interim or final periodic.

• Interim spousal support: La. Civ. Code arts. 113–115
• Final periodic spousal support: La. Civ. Code art. 111

In DocketMath, use the timing selector (or the closest available option) to match what you’re trying to estimate.

5) If you selected final periodic spousal support, apply the “freedom-from-fault” context

If your goal is to estimate final periodic spousal support, remember that La. Civ. Code art. 111 involves the freedom-from-fault threshold concept.

Practically, in DocketMath you may see this reflected as:

• a factor/checkbox input related to eligibility context, or
• a scenario/timing selection that routes the computation under the final periodic model.

If the tool does not ask a fault-related question directly, treat the output as an estimate based on the calculator’s modeled categories, not as a legal determination.

6) Run the calculation and review outputs (child vs spousal separately)

After you click Calculate, DocketMath should show separate outputs for:

• Child support (Louisiana schedule approach under La. R.S. § 9:315.19)
• Spousal support (Civil Code approach under La. Civ. Code arts. 111–117, with interim handled by arts. 113–115)

Output review checklist:

• Adjust income and confirm the child support amount responds as expected (income-shares sensitivity)
• Switch interim vs final periodic and confirm the spousal support amount changes accordingly
• Save/record both results so you can compare scenarios side-by-side

7) Use “what-if” adjustments to see which inputs matter most

For Louisiana, the fastest way to learn driver factors in DocketMath is to change one variable at a time:

• Change Parent A income while holding Parent B constant
• Adjust parenting time allocation and watch how the child-support figure moves
• Switch spousal timing between interim and final periodic to see the effect of arts. 113–115 vs art. 111

This helps you understand which fields most strongly impact the outputs in your specific scenario.

Common pitfalls

These issues commonly cause confusion when running Alimony + Child Support in DocketMath for Louisiana.

1. Mixing up child support vs spousal support frameworks

   • Child support is tied to La. R.S. § 9:315 et seq., specifically the schedule at La. R.S. § 9:315.19
   • Spousal support is tied to La. Civ. Code arts. 111–117

   Result: If you assume inputs apply only to one category, you may misinterpret the output—DocketMath routes numbers according to category.

2. Entering parenting-time/custody data inconsistently Louisiana child support results can shift with parenting-time allocation. Double-check:

   • you entered the correct number of children
   • the custody/parenting-time numbers are in the format the tool expects

3. Selecting the wrong spousal-support timing (interim vs final periodic)

   • Interim uses La. Civ. Code arts. 113–115
   • Final periodic uses La. Civ. Code art. 111

   If the timing is wrong, the spousal portion can be skewed even if income and children are correct.

4. Assuming “alimony” works the same across states Even if the term is familiar, the governing structure differs by jurisdiction. In Louisiana, the statute framework is specifically anchored to:

   • child support statutes (La. R.S. § 9:315 et seq.; schedule La. R.S. § 9:315.19)
   • spousal support articles (La. Civ. Code arts. 111–117)

Try it

Run a quick Louisiana scenario in DocketMath:

1. Go to /tools/alimony-child-support
2. Set jurisdiction to US-LA
3. Enter:

   • Parent incomes (monthly)
   • Number of children
   • Parenting-time allocation
   • Spousal-support timing (interim or final periodic)
4. Click Calculate
5. Change one variable at a time and observe how outputs change:

   • Income (e.g., +10% for Parent A)
   • Parenting time allocation
   • Interim vs final periodic timing

A simple comparison plan:

• Baseline scenario
• Income-adjusted scenario (e.g., +10% for Parent A)
• Timing-adjusted scenario (interim vs final periodic)
