Rule or statute summary

Run this scenario in DocketMath using the Pre Post Offer Damages Split calculator.

Brazil’s pre / post offer damages split in civil money claims generally turns on (a) when the debtor is deemed in default (mora) and (b) how interest and monetary correction (correção monetária) are calculated before vs. after the procedurally effective judicial offer that triggers/changes the default-related regime.

For modeling purposes, DocketMath’s pre-post-offer-damages-split snapshot is designed to split damages into two timelines:

Pre-offer period: from the damages accrual point (or the valuation anchor you’re using) up to the offer-effective date (the point in the proceeding when the offer becomes effective/produces effects, not merely when it was drafted).
Post-offer period: from the offer-effective date onward, when default-linked effects (including how interest and correction are treated) typically become applicable under the calculator’s Brazil configuration and the assumptions you select.

A practical way to think about it:

More time in the pre-offer bucket → typically increases the pre-offer portion of the damages (and correspondingly reduces the post-offer portion).
Earlier offer-effective date → shifts more value into the post-offer bucket.
Different start-date choices (accrual date vs. offer-effective date) can materially change the split—even if the base principal is the same.

Pitfall: “Offer date” is not always the same as “filing date.” For a reliable pre/post split, define the offer’s effective date using the procedural record (e.g., the moment it becomes opposable or otherwise procedurally relevant), not only the calendar date the document was submitted or signed.

What this snapshot does (and doesn’t)

✅ Does: provide jurisdiction-aware inputs and explain how outputs change when you adjust dates and amounts.
❌ Doesn’t: confirm how a particular court will apply interest/correction start points for your exact claim type or argue your case. This is a calculation aid, not legal advice.

Citations

Brazilian damages modeling commonly references the Civil Code provisions that structure default (mora) and the logic for losses, interest, and compensation mechanics, plus procedural rules in the Code of Civil Procedure (CPC) that govern how judicial offers operate in practice.

Commonly used starting points include:

**Civil Code (Código Civil)
- Article 397 (default / mora concept tied to payment obligation and triggers)
- Article 389 (losses and interest concepts)
- Article 404 (interest in compensation contexts, including when in default)
**Civil Procedure Code (Código de Processo Civil — CPC)
- Offer-related provisions (the exact CPC article(s) depend on the type of judicial offer shown in your docket record—e.g., whether it is an offer mechanism with procedural consequences similar to “accept/reject” style outcomes, deposit-based offers, or other settlement/damages consequences).
- Because the template is generic, you should align the calculator inputs to the procedural label used in your specific record.
Practice on correção monetária vs. interest
- Brazilian practice frequently treats monetary correction and interest as related but distinct components, with start points that can depend on what kind of damages you’re modeling and how valuation/accrual is defined (property vs. non-property; contractual vs. extra-contractual; etc.).
- The safest approach for a snapshot is to split timelines around the offer-effective date, while using the calculator’s Brazil rules/assumptions rather than asserting one universal start date.

Sources and references

TODO: Add the exact CPC article(s) corresponding to the specific offer mechanism reflected in the template/case record (paste the docket label and I’ll help map it to the correct CPC concept for your snapshot inputs).
TODO: Add the relevant higher-court (STJ/STF) precedent(s) that describe the start-date methodology for correção monetária and juros for the damages category you’re modeling.
Note: Until those are filled, treat this section as a framework citation scaffold, not an exhaustive authority list.

Start with the primary authority for Brazil and confirm the effective date before relying on any output. If the rule has been amended, update the inputs and rerun the calculation.

This workflow helps you produce a reference snapshot for Brazil that separates damages into pre- and post-offer components using jurisdiction-aware rules.

Run the Pre Post Offer Damages Split calculation in DocketMath, then save the output so it can be audited later: Open the calculator.

Step 1: Enter the core dates (highest impact)

Damages accrual date (start of the pre-offer period)
- This is your chosen anchor (e.g., date harm occurred, invoice became due, or a valuation milestone).
Offer effective date (end of the pre-offer period)
- Use the procedurally effective date (not just the date the offer was filed or signed).
End date for the calculation window (estimation horizon)
- Example: today (e.g., 2026-04-15) or a reporting cut-off (e.g., 2025-12-31).

Step 2: Enter the damages base amount

Principal / base amount (nominal figure before applying the calculator’s correction/interest mechanics).
- Example: BRL 250,000.00

Step 3: Configure the split mechanics (Brazil assumptions)

DocketMath computes:

Pre-offer damages amount: base principal adjusted according to the calculator’s Brazil pre-offer logic (including how it handles monetary correction and any pre-mora interest assumptions).
Post-offer damages amount: base principal adjusted under the Brazil post-offer logic (with default-linked effects starting from the offer-effective date, per the calculator’s configuration).

How outputs change when you move dates:

Move the offer-effective date later → you generally allocate more time to the pre-offer bucket → pre-offer increases, post-offer decreases.
Move the offer-effective date earlier → shift time into the post-offer bucket → post-offer increases, pre-offer decreases.
The total can also change if the calculator applies different mechanics pre vs. post.

Warning: Don’t compare two outputs if they use different “offer effectiveness” definitions (e.g., one using filing date and another using procedural effectiveness). The pre/post allocation can flip.

Step 4: Interpret the outputs (what to record)

A typical output set includes:

Output line	Meaning	Sensitivity to offer-effective date
Pre-offer period value	Damages through the offer-effective date	Usually rises if offer-effective date moves later
Post-offer period value	Damages from offer-effective date onward	Usually rises if offer-effective date moves earlier
Total estimated amount	Pre + post sum	Can shift depending on pre vs. post mechanics
Effective split ratio	% attributed to pre vs. post	Useful for settlement modeling (not legal advice)

Mini example (date sensitivity check)

Assume:

Principal: BRL 250,000.00
Accrual date: 2022-03-14
Offer effective date: 2023-05-10
End date: 2026-04-15

If you change the offer effective date to 2023-02-01 (earlier by ~100 days):

Pre-offer time shortens → pre-offer value generally decreases
Post-offer time lengthens → post-offer value generally increases
The total may vary depending on whether the calculator applies materially different interest/correction mechanics in each period.
