Spreadsheet checks before running Closing Cost in Maine

What the checker catches
Run this scenario in DocketMath using the Closing Cost calculator.
If you’re calculating closing costs in Maine with DocketMath (calculator: closing-cost), your spreadsheet can silently drift out of compliance—especially when timing assumptions or deadline windows end up embedded in formulas. A jurisdiction-aware spreadsheet checker helps you catch those issues before you run or finalize the closing-cost calculation.
For Maine, a key timing input that many “close-the-loop” spreadsheets encode is the general statute of limitations (SOL) period. Per the general/default rule:
- General SOL period (default): 0.5 years
- Source: Title 17-A, §8

Important clarification: No claim-type-specific SOL sub-rule was identified for this checker. That means the spreadsheet should use the general/default 0.5-year SOL rather than attempting to vary the SOL by claim type.
The checker’s high-value checks (US-ME)
Below are the kinds of issues this checker looks for in your workbook logic—so your closing-cost output doesn’t depend on an invalid timing assumption.
| Spreadsheet risk | What the checker detects | Why it matters for closing-cost outputs |
|---|---|---|
| SOL period hard-coded incorrectly | Confirms the model uses the general/default SOL of 0.5 years | If your sheet offsets or windows costs using “time remaining,” a wrong period can skew totals |
| Conflicting date math | Looks for inconsistent conversions between days/months/years | Small rounding differences can compound across multiple calculations |
| Missing date inputs | Flags blank or placeholder “effective date” / “calculation start date” cells | Many closing-cost components depend on when the “clock” starts |
| Logic branching that assumes claim-specific rules | Ensures the sheet doesn’t attempt to apply a non-existent claim-type-specific SOL sub-rule | With no claim-type-specific sub-rule identified, the safe behavior is sticking to the general/default period |
| Units mismatch in time windows | Checks whether formulas treat 0.5 years as “6 months” vs “182.5 days” inconsistently | Different conventions change which items fall “inside” the time window |
Note: This checker is using the general/default Maine SOL period of 0.5 years under Title 17-A, §8. No claim-type-specific SOL sub-rule was found, so the spreadsheet should not try to vary the SOL by claim type.
How the output changes when a check fails
When the DocketMath spreadsheet checker detects an inconsistency, it typically impacts one or more of the outputs that depend on time-window logic. Common affected areas include:
- Any “time-windowed” fees (items included only if they fall within a specified time window)
- Proration multipliers tied to elapsed time or remaining time
- Totals that rely on intermediate calculations like “days since X” → “years since X”
- Scenario comparisons where one branch uses corrected timing and the other branch still uses stale or incorrect logic
In other words, the goal isn’t only to catch a single wrong number—it’s to prevent a chain reaction from a single incorrect time assumption.
When to run it
Run the checker immediately before you compute or finalize closing-cost totals. That timing catches both missing inputs and “formula drift” from recent edits.
Run the checker before importing a spreadsheet into the Closing Cost workflow. It is especially helpful when you have multiple entries or when a teammate provided the inputs.
Recommended run points (practical workflow)
- After you enter dates (e.g., purchase date, closing date, or any “calculation start date” your sheet uses)
- Before you lock totals for a quote or internal approval
- After you copy formulas into new scenarios (variant A vs variant B)
- Whenever you change SOL-related logic (even if you only edit one cell, one named range, or one time-window parameter)
A quick checklist you can follow:
What not to do
Avoid running the checker once and assuming it stays valid. Spreadsheet logic often changes incrementally—especially when multiple people update a file—so the safest move is to re-check right before output.
Try the checker
You can run the DocketMath closing-cost workflow and have the spreadsheet checker verify the Maine-specific timing assumption for the general/default SOL period.
Start here:

Upload the spreadsheet, review the warnings, and then run the calculation once the inputs are clean: Try the checker.
What inputs to review (before you click “calculate”)
In your spreadsheet (and/or in the inputs you provide to DocketMath), focus on:
- SOL period setting / parameter
- Maine: 0.5 years (general/default)
- Based on: Title 17-A, §8
- Any date used to compute “elapsed time”
- Closing date vs. calculation start date
- Any proration formula
- Look for multipliers like:
elapsed_years / 0.5or “months remaining”
- Any conditional statements
- Example structure:
IF(elapsed_time <= SOL_window, include_fee, exclude_fee)
Expected outcomes from a successful run
A clean checker pass typically means:
- Your workbook’s timing logic aligns with Maine’s general/default SOL of 0.5 years
- Date math uses consistent units and conversion logic
- Your closing-cost total reflects the corrected assumptions (no hidden offsets from unit conversion or branch logic)
Warning: If your spreadsheet includes a “claim-type-specific SOL” variation, but you don’t have an identified rule in this setup, the checker may flag the logic as inconsistent. The safe default here is the general/default SOL period of 0.5 years under Title 17-A, §8.
Gentle disclaimer
This checker and walkthrough are meant to reduce spreadsheet errors by aligning calculations with a specific jurisdiction-aware timing parameter. It’s still your responsibility to ensure your overall model matches the facts and legal framework you intend to apply.
