Spreadsheet checks before running statute of limitations in Maine

What the checker catches
DocketMath’s statute-of-limitations spreadsheet checker is designed to catch the “spreadsheet bugs” that can silently distort dates before you even decide anything about a Maine deadline. Since you’re working in Maine (US-ME), the checker is built around the general/default statute of limitations—not a claim-type-specific one.
Use the general/default rule as the starting point (Maine)
Maine’s general statute of limitations is in Title 17-A, § 8. In this jurisdiction dataset, the general SOL period is 0.5 years. Because no claim-type-specific sub-rule was provided, this general/default period is the rule this checker assumes you’re using.
Important scope reminder: This checker uses the general/default period (0.5 years under Title 17-A, § 8) because no claim-type-specific sub-rule was identified for this template. If your matter involves a different limitation rule than the general one, update your spreadsheet inputs to reflect that before relying on any computed dates.
Spreadsheet issues it can flag
Here are common spreadsheet problems that lead to wrong “deadline” outputs:
- Wrong date column used
- Example: you calculate from “discovery date,” but the sheet references “incident date” (or vice versa).
- Off-by-one day logic
- Example: adding 0.5 years but converting it incorrectly (365 vs. 366 day years; rounding mid-year).
- Rounding drift
- Example: converting 0.5 years to months (6 months) but then adding months with end-of-month behavior that shifts the day.
- Mixing date formats
- Example: one row uses
MM/DD/YYYY, another usesYYYY-MM-DD, causing silent mis-parsing.
- Blank or malformed cells
- Example: “Date filed” is empty for some rows, but the formula still computes a deadline based on a default or leftover value.
- Time-zone or timestamp contamination
- Example: a datetime like
2024-01-15 23:30causes day rollovers when normalized.
- Unit confusion
- Example: entering “0.5” as “0.5 days” somewhere while other fields treat it as years.
Output behaviors to sanity-check
When the checker runs, verify that:
- The deadline date changes logically when you change the input trigger date by ±1 day.
- Rows with missing dates don’t produce “plausible” deadlines silently.
- The 0.5-year conversion is consistent across rows (same strategy every time).
To make this practical, structure your spreadsheet so the checker can validate each assumption using:
- a clear start date column
- a consistent calculated deadline column
- an error/warning/status column (even if it’s just “OK” vs “Fix”)
When to run it
Run the checker in a staged workflow so you catch issues early—before you interpret legal meaning. This is not legal advice; it’s spreadsheet debugging to help ensure your math and date handling are behaving as intended.
Run the checker before importing a spreadsheet into the Statute Of Limitations workflow. It is especially helpful when you have multiple entries or when a teammate provided the inputs.
Recommended order
- Step 1: Before computing deadlines
- Confirm all date fields are valid and consistently formatted.
- Step 2: After formulas are set
- Ensure the checker can evaluate the outputs (deadline dates) row-by-row.
- Step 3: After bulk edits
- Re-run after copying/auto-filling rows, importing CSV data, or adjusting start date logic.
- Step 4: Right before export or reporting
- This catches last-mile problems—like one column being shifted after a spreadsheet resize.
“Change triggers” for a re-run
Re-run DocketMath’s checker if any of these happen:
- You updated the start date logic (e.g., switching from “incident” to “reported”).
- You changed date entry method (manual → import, or import → paste).
- You altered the 0.5-year conversion approach in any formula (e.g., months vs. days).
- You edited rounding behavior or helper columns.
Warning: Spreadsheet errors often look confident—producing a real-looking date even when the logic is wrong. Re-check before you rely on outputs.
What the checker expects from your inputs
For Maine’s default dataset, your sheet should treat the limitation period as 0.5 years anchored to the relevant start date you’re using. Your checker run should confirm:
- the start date is present (where applicable)
- the limitation period is treated as years (not months/days unless you intentionally re-express it)
- the deadline calculation is deterministic (same inputs → same outputs)

Use the general/default rule for Maine with Title 17-A, § 8 and a limitation period of 0.5 years. If you need the statute reference, use:
Checklist for your spreadsheet run
Use this quick checklist before relying on the deadline output:
How inputs change outputs (what to test)
Pick 2–3 rows and run micro-tests:
- Change a start date by +1 day
- The computed deadline should generally move forward by about the same magnitude (allowing for your chosen rounding strategy).
- Change a start date by -1 day
- The computed deadline should move backward accordingly.
- Remove a start date in one row
- The checker should not produce a normal-looking deadline—there should be a warning/error.
If any of these don’t behave as expected, fix the spreadsheet logic first, then re-run.
Important scope reminder (again)
This workflow is centered on the general/default period (0.5 years) from Title 17-A, § 8, since the dataset provided does not identify a claim-type-specific sub-rule. If you determine a different limitation period applies, update your spreadsheet’s rule first, then re-run the checker.
