Inputs you will need

Run this scenario in DocketMath using the Damages Allocation calculator.

Damages allocation in Illinois using DocketMath’s damages-allocation tool works best when you prepare a consistent, structured set of inputs. Even if your damages theory is broad (for example, mixed compensatory categories), the tool generally needs clearly separated categories and the date inputs that drive the limitations-window logic.

Below is a practical input-checklist tailored to Illinois (US-IL) for the input-checklist template and the /tools/damages-allocation calculator.

Core damages-allocation inputs (build your dataset)

Use these items as your baseline list:

Timing input you’ll need for Illinois (general SOL)

DocketMath’s damages allocation can depend on what portion of damages falls within the applicable limitations window. For Illinois, the provided jurisdiction data indicates the general/default limitations period applies because no claim-type-specific sub-rule was found.

Important: Because no claim-type-specific sub-rule was found in the provided jurisdiction data, the workflow should use the general/default 5-year period as the working SOL window.

Note: This is an inputs-and-calculation workflow for DocketMath. It’s not legal advice and doesn’t create an attorney-client relationship. Use it to structure your analysis and document assumptions.

Where to find each input

To keep your timeline defensible and your numbers consistent across filings and discussions, pull these inputs from sources you can point back to later.

Most inputs live in the case file, contracts, or docket entries. Dates usually come from the triggering event notice; rates and caps come from governing documents or statute; and amounts come from the ledger or judgment. Record the source for each value so the run is reproducible.

1) Dates (Claim date / injury date; Filing date)

Typical sources:

Where this affects allocation:

  • DocketMath uses your claim/injury date and your filing/timeline anchor to apply the 5-year window under 720 ILCS 5/3-6.

2) Category amounts (Dollar amounts by category)

Typical sources:

Tip for clean allocation:

  • Put totals in the tool exactly as they appear in your supporting exhibits/spreadsheets.
  • If you have subcomponents (for example, multiple economic lines), consider whether you want them combined into one category amount (if the tool allocates at the category level) or entered separately (if your methodology requires it).

3) Proof basis per category

This can be brief, but it should exist:

Why it helps:

  • Even if DocketMath doesn’t require legal citations, a proof basis note helps you reconcile your calculation results with the evidentiary record.

4) Allocation methodology and constraints

Inside DocketMath under /tools/damages-allocation, select the method that matches how you want the tool to allocate:

Common pitfall:

  • Entering correct gross category totals but leaving out—or mis-stating—the dates that define the 5-year SOL window can skew the portion of damages treated as within the limitation period under 720 ILCS 5/3-6.

Run it

After collecting inputs, run DocketMath using the Illinois default SOL window:

  1. Open /tools/damages-allocation (Primary CTA)
  2. Enter:
    • [Optional but recommended] Notes/proof basis
  3. Confirm the SOL logic is using:
    • General limitations period: 5 years
    • Statute: 720 ILCS 5/3-6
    • General/default period (since no claim-type-specific sub-rule was identified in the provided jurisdiction data)

How outputs will change when you change inputs

Use these “cause → effect” checks to sanity-test results:

Input you adjustWhat typically changes in allocation output
Filing date moves later (same injury date)A larger share of damages may fall within the 5-year window
Filing date moves earlierA smaller share may fall within the 5-year window
Category amount increasesAllocated totals for that category increase proportionally (subject to your selected allocation method)
You alter methodologyDistribution across categories can change even if overall totals are similar

Practical validation steps

Before you finalize:

If you’re ready to proceed, start here: /tools/damages-allocation.

Warning: If your damages timeline spans multiple periods (for example, incurred from 2017 through 2023), ensure your claim/injury date and filing date reflect the time window your damages model is tracking; otherwise the portion treated as within 720 ILCS 5/3-6’s 5-year window may not match your evidence.
