How to calculate pre/post-offer damages split in Louisiana

Quick takeaways

• Louisiana uses the offer of judgment framework in La. Code Civ. Proc. art. 970 to decide whether an offer triggers enhanced consequences, including a pre-/post-offer damages split.
• In DocketMath’s pre/post-offer damages calculator, you’ll separate the final judgment total into:

  • Pre-offer amounts (the “baseline” recovery conceptually tied to the offer), and
  • Post-offer amounts (the “increment” beyond that baseline tied to what the plaintiff-offeree obtained after the offer).
• The timing rule is the general/default one: an offer may be served “at any time more than twenty days before the time specified for the trial.”
• You’ll need:

  • Offer service date
  • Trial date (the date “specified for the trial”)
  • Offer amount
  • Final judgment amount (entered consistently with what you call “damages” in your workflow)
• If the plaintiff-offeree’s recovery meets the statute’s 25% threshold (the statute text you provided includes: “If the final judgment obtained by the plaintiff-offeree is at least twenty-five p...”), the calculator’s split logic applies accordingly.

Inputs you need

To calculate a pre/post-offer damages split in Louisiana (US-LA) with DocketMath, collect these inputs from your case file, proof of service, scheduling order, and judgment.

1) Offer timing inputs (art. 970 trigger)

• Offer service date (not just the date drafted—use the served date from proof of service)
• Trial date (the date “specified for the trial” in the controlling order)
• (Optional for precision) Amended trial date (if the order was later updated, confirm which trial date controls)

2) Offer amount and judgment outcome inputs

• Offer amount (the amount stated “for the property or to the effect specified in the offer”)
• Final judgment amount obtained by the plaintiff-offeree

  • Decide whether you will treat this as damages only or damages + specific components (for example, some teams handle certain statutory additions or interest separately)

3) Consistent mapping to your split definition

Because a split depends on what you feed into “final judgment,” set your workflow definition up front:

• How your team defines “final judgment amount” for splitting:

  • Include only principal damages, or
  • Include principal + specified statutory components (pick one approach and keep it consistent)
• How you want to treat non-damages items (common examples: costs and interest)

  • Even when the calculator focuses on damages, your “damages figure” should match what you intend to split.

Quick reference checklist (minimum viable dataset)

• Offer service date
• Trial date
• Offer amount
• Final judgment amount

How the calculation works

This section describes the Louisiana-aware logic you apply when using DocketMath’s pre/post-offer damages calculator.

Step 1: Confirm the offer qualifies under the “more than 20 days” rule

Art. 970 permits service “at any time more than twenty days before the time specified for the trial.” Practically, you want to confirm the offer service date is more than 20 days earlier than the controlling trial date.

Practical math check

• Compute: Trial date - Offer service date
• If the result is greater than 20 days, the offer satisfies the general/default timing requirement used here.

Step 2: Apply the 25% threshold trigger

The statute excerpt you provided includes the threshold concept:

• “If the final judgment obtained by the plaintiff-offeree is at least twenty-five p...”

In a DocketMath workflow, this threshold is tested by comparing:

• Final judgment amount (plaintiff-offeree’s result), to
• Offer amount

Most implementations reflect this as a ratio test (conceptually):

• Final judgment ÷ Offer amount
  and confirm whether it reaches the 25% threshold required by art. 970.

Important: If your “final judgment amount” input includes components you’re not treating as part of the “damages” comparison, you can unintentionally change whether the threshold appears to be met. Use a single, consistent definition.

Step 3: Compute the pre-/post-offer damages split

When timing and threshold requirements indicate the offer consequences apply, DocketMath splits the outcome into:

• Pre-offer damages: the portion treated as the baseline recovery associated with the offer stage
• Post-offer damages: the remaining portion treated as additional recovery obtained after the offer

A common operational approach (and the one that maps cleanly into a “baseline vs. realized total” model) is:

• Pre-offer portion = the offer amount (or the equivalent baseline your workflow maps to “pre-offer”)
• Post-offer portion = Final judgment amount - Pre-offer portion

If the final judgment equals (or is very close to) the offer amount—given your definitions—the post-offer increment may be small or zero.

Step 4: Handle costs and interest consistently

Art. 970’s excerpt also references “costs then accrued.” That means costs can matter in the statute’s operation, even if the calculator is focusing on the damages split.

For DocketMath:

• Decide whether your input “final judgment amount” is:

  • damages-only, or
  • damages + certain components you explicitly include
• Keep that alignment with how you plan to interpret the output.

Disclaimer: This is a practical workflow explanation, not legal advice. Always confirm the exact statutory language and how Louisiana courts apply art. 970 to your specific posture.

Common pitfalls

1) Using the wrong “offer date” (draft date vs. served date)

Art. 970 keys off when the offer is served. Use the proof-of-service service date, not the date someone emailed or signed the document.

2) Miscounting the “more than 20 days” window

• Exactly 20 days does not satisfy “more than twenty days.”
• Make sure you’re measuring against the controlling “time specified for the trial.”

3) Comparing inconsistent figures (threshold vs. split inputs)

If you input:

• an offer amount that is purely principal, but
• a final judgment amount that includes interest/costs you did not intend to count, your ratio test and split can both skew.

4) Assuming claim-type-specific timing rules exist

Based on the provided materials, no claim-type-specific sub-rule was found. Use the general/default period only:

• more than 20 days before trial.

5) Running the calculator without verifying the operative offer

If there are multiple offers (or an amended/superseded offer), ensure you input the operative one you intend to analyze.

Next steps

1. Open DocketMath’s Louisiana tool: /tools/pre-post-offer-damages
2. Enter the required inputs:

   • Offer service date
   • Trial date
   • Offer amount
   • Final judgment amount (using your chosen “damages” definition)
3. Review the output split and then sanity-check:

   • whether the timing screen would be satisfied (>20 days), and
   • whether the 25% threshold appears to be met under your inputs.
