Step-by-step

This guide walks you through running Closing Cost in DocketMath for Massachusetts (US-MA) using jurisdiction-aware timing rules. It’s written to help you model the statute-of-limitations (SOL) window for timing-related analysis—not to provide legal advice.

Note: Massachusetts has a general/default SOL period of 6 years. For this workflow, the jurisdiction data points to the general statute: Mass. Gen. Laws ch. 277, § 63. No claim-type-specific sub-rule was found for this run, so the calculator uses the general/default period.

1) Open the Closing Cost calculator

Go to the Closing Cost tool: **/tools/closing-cost
Confirm you’re using Massachusetts (US-MA) in the jurisdiction selector (or confirm the tool defaults to US-MA).

2) Identify the date inputs you’ll use

The Closing Cost workflow produces outputs based on dates that determine when a claim period starts and ends. Before you enter anything, collect:

Trigger date: the date that starts the timing calculation in your workflow
Relevant date: the date you compare against the computed SOL deadline (often a filing date or another key event date)
Any other calculator-specific inputs shown on the screen (for example, cost/amount fields)

If you already know the tool expects specific fields (such as “from” and “to” dates), map your real-world dates to the calculator carefully and keep a note of your assumptions. That way, you can reproduce your results later.

3) Enter values in DocketMath

In the Closing Cost calculator:

Select US-MA / Massachusetts
Enter dates exactly as the calculator format requires (for example, month/day/year)
Enter any closing cost or amount fields required by the calculator

Then run the calculation.

4) Make sure the SOL window is using the correct Massachusetts rule

In this Massachusetts workflow, DocketMath should apply the general/default SOL period:

6 years under Mass. Gen. Laws ch. 277, § 63
The jurisdiction dataset indicates no separate claim-type-specific sub-rule was found for this run

To validate, review the tool output for language that confirms:

The SOL period is 6 years, and
The run is aligned with ch. 277, § 63

If the output doesn’t reference the expected statute or doesn’t show 6 years, double-check the jurisdiction selection and any related settings in the tool.

5) Review the output fields and how they change with inputs

After you run the calculator, focus on both (a) SOL/timing results and (b) any closing-cost outputs the workflow computes.

A practical way to read the results:

Output type	What it represents	How it changes when you update inputs
SOL end date / deadline	The last date within the applicable SOL window	Typically moves forward/backward when you change the trigger date
SOL duration used	The length of the SOL window applied (expected: 6 years)	Should remain 6 years for this workflow because the rule is general/default
Timing comparison	Whether the relevant date is inside or outside the computed deadline	Flips when the relevant date crosses the computed deadline
Closing-cost totals	Any calculated closing cost figures tied to the workflow	Changes with cost/amount inputs (not necessarily with SOL timing, unless the tool couples them)

Because this workflow uses a fixed 6-year SOL period (Mass. Gen. Laws ch. 277, § 63), the biggest driver of changes in SOL-related outputs is usually your trigger date.

6) Document your assumptions for reproducibility

Even for internal workflows, it’s smart to record the assumptions that affect the calculation. At minimum, write down:

What you used as the trigger date
What you used as the relevant date
Any estimated values or non-obvious assumptions for cost/amount fields

This helps you explain why a re-run produces different results if you later update dates or inputs.

Common pitfalls

These are frequent issues people run into when running Closing Cost / timing-related calculators for Massachusetts using a general SOL period.

Using a 3-year or 4-year window from another jurisdiction
- For this workflow, Massachusetts general/default SOL is 6 years under Mass. Gen. Laws ch. 277, § 63.
Mixing up the “trigger” and “relevant” dates
- Swapping a single date can shift the computed deadline and change the timing comparison (inside/outside the SOL window).
Assuming there’s a claim-type-specific SOL rule in the dataset
- The jurisdiction data for this run indicates no claim-type-specific sub-rule was found. The calculator therefore uses the general/default period.
Entering dates in an inconsistent format
- Even if there’s a date picker, verify the year and month/day. A small entry error can shift the deadline by months or years.
Treating SOL timing outputs as legal strategy
- Tool results can support analysis, but they don’t replace legal judgment. Use the calculator’s outputs as modeling inputs and confirm key details with appropriate review.

Warning: If you rely on SOL timing outputs for a decision, make sure the underlying dates accurately match how the tool defines the timing “start” (trigger date) and the comparison point (relevant date). A wrong assumption about the trigger date can make a deadline appear missed or met incorrectly.

Try it

Open **/tools/closing-cost
Set **Jurisdiction: US-MA (Massachusetts)
Enter:
- A trigger date
- A relevant date
- Any closing cost amounts/fields shown in the calculator UI
Run the calculation and confirm:
- The SOL period displayed is 6 years
- The output aligns with Mass. Gen. Laws ch. 277, § 63
Do a quick stress test:
- Move only the trigger date forward by 30 days
- Re-run the calculation
- Watch how the computed SOL deadline and any “inside/outside” timing comparison shift

This helps you identify which input most strongly affects the timing portion of the output.

Quick checklist for your first run:

If your output includes a deadline and/or an “within SOL” comparison, prioritize verifying that the computed deadline matches what you’d expect from a 6-year window based on your chosen trigger date.
