Spreadsheet checks before running Alimony Child Support in Louisiana

What the checker catches
Before you run an alimony + child support spreadsheet in Louisiana (US-LA) with DocketMath, it helps to run quick, jurisdiction-aware checks that prevent two of the most common spreadsheet failures: (1) wrong timelines for eligibility-related calculations and (2) misapplied assumptions that quietly skew totals.
DocketMath’s Spreadsheet checker is built to catch problems before you generate numbers in the Alimony Child Support calculator: /tools/alimony-child-support . In Louisiana, one jurisdiction rule that can matter for “do we include this time period / claim window?” decisions is the default statute of limitations (SOL) period you may be implicitly relying on when your spreadsheet includes or excludes time ranges.
SOL timing guardrail (default rule)
The jurisdiction data provided for this content states the following:
- General/default SOL period: 1 year
- General Statute: La. Rev. Stat. Ann. § 9:2800.9
Important clarity: The jurisdiction data also indicates no claim-type-specific sub-rule was found. That means the guidance below uses the general/default 1-year period only (not a special shorter/longer window for a specific claim category).
What the checker is trying to prevent: a spreadsheet that includes a time span wider than the general 1-year window while treating that time span as though it’s safely included—simply because the dates were entered and the calculator aggregated amounts automatically.
Common issues the checker flags in practice
Use this checklist as a mental model of the types of spreadsheet issues DocketMath’s checker can detect before totals are computed:
(Example: intake date after the event date, or end date before start date.) (Example: you adjust an amount assumption but forget to update the corresponding date range.) (Example: a toggle cell quietly falls back to 0, 1, or “FALSE” and changes the result.)
Warning: A spreadsheet can “look right” while being wrong if the date range crosses a 1-year general SOL period tied to La. Rev. Stat. Ann. § 9:2800.9. Because support calculations often aggregate time-based amounts, the numeric outcome may reflect an eligibility/timing window you shouldn’t assume.
How the checker changes outputs (without doing the math yet)
Instead of immediately calculating support, the checker focuses on whether your inputs pass feasibility and consistency tests.
When a timing issue is detected, you’ll typically see one of these outcomes:
- a blocked run (you may need to correct dates/fields before proceeding), or
- a warning indicating your timeline inputs fall outside the general 1-year SOL guardrail, prompting you to revise the inputs or the time span used in your calculations.
Either way, the goal is the same: catch timing problems early, before they ripple into totals.
When to run it
Run the checker before you press “calculate,” and again any time dates change. It’s especially helpful in these situations:
Run the checker before importing a spreadsheet into the Alimony Child Support workflow. It is especially helpful when you have multiple entries or when a teammate provided the inputs.
1) First pass intake (new spreadsheet)
When you’re building the worksheet from scratch, the checker helps you confirm:
- you entered event dates and effective dates correctly
- your spreadsheet uses a coherent time interval (start before end)
- your date range aligns with the general 1-year period referenced from La. Rev. Stat. Ann. § 9:2800.9
2) After you adjust timeline assumptions
Common triggers include:
- you update the filing date
- you change the start date for a support-related calculation window
- new facts shift the end date used for averaging or proration
Even small changes (like moving a start date forward or backward) can move you into or out of the general 1-year timing guardrail—so re-running the checker reduces the risk of “accidentally out-of-scope” time windows.
3) Before you share numbers
If you’re generating outputs for discussion (for example, a negotiation draft or a case status packet), run the checker one last time. This helps reduce spreadsheet drift, where later edits to unrelated cells create mismatched outputs.
Pitfall: Spreadsheet drift often happens when one tab uses “today” as an end date while another tab uses a different cutoff date. Consistency checks are designed to prevent that kind of silent mismatch.
Try the checker
You can try this workflow using DocketMath’s calculator entry point:
- Open ** /tools/alimony-child-support
- Enter the calculator inputs for your scenario
- If the Spreadsheet checker step appears in the flow, complete it before running the totals
Input habits that reduce errors
To make the checker more effective—and your results more reliable—try to:
- Use actual dates (for example, YYYY-MM-DD) rather than approximations like “about March”
- Keep one source of truth for key dates (for example, a single “Start Date” cell referenced across tabs)
- Avoid mixing event date and effective date in the same field
What to watch for after running the checker
After you run the checker, look for:
| Checker outcome | What it likely means | Action to take |
|---|---|---|
| Dates OK (no SOL timing warning) | Your time span fits the general 1-year guardrail | Proceed to the alimony/child support calculation |
| Warning about SOL timing window | Inputs imply a period outside the general/default 1-year timeframe under La. Rev. Stat. Ann. § 9:2800.9 | Adjust date inputs or revise the calculation window used in your spreadsheet |
| Missing/invalid date errors | Fields are blank, reversed, or inconsistent | Fix the date order/consistency and rerun the checker |
Note: The 1-year timing guardrail here is the general/default period you provided. Since no claim-type-specific sub-rule was identified, this should be treated as a default timing check, not a complete mapping of every possible Louisiana claim category.
Finally, a gentle reminder: this is a spreadsheet-checking workflow, not legal advice. DocketMath is intended to help you validate inputs and reduce spreadsheet mistakes—while you make final decisions based on the facts of your case and applicable Louisiana law.
