Spreadsheet checks before running Closing Cost in New Jersey

What the checker catches

Run this scenario in DocketMath using the Closing Cost calculator.

If you’re running Closing Cost calculations in New Jersey with DocketMath, one of the most avoidable mistakes is letting your spreadsheet move forward without verifying that the underlying timing rules match the appropriate statute of limitations (SOL) window. DocketMath’s closing-cost flow helps turn raw fields (dates, amounts, fees) into structured outputs, but a checker can still catch spreadsheet problems that would otherwise produce results that look consistent while being time-inconsistent.

Below are the key issues a New Jersey–aware spreadsheet checker should help you catch before you run and trust Closing Cost.

1) Date gaps that break the 4-year default SOL window

For this checker, the controlling timing rule is the general/default SOL period of 4 years under N.J.S.A. 12A:2-725. (No claim-type-specific sub-rule was found for this brief, so this guide treats the general SOL as the default for spreadsheet timing checks.)

If your spreadsheet uses dates such as an invoice date, delivery/accrual date, notice date, or another “start” date, and your comparison “target” date falls more than 4 years after the chosen start date, the Closing Cost output can be misleading—because the underlying claim timing may be time-barred even if the spreadsheet totals look correct.

A solid checker should validate, at minimum:

• The “starting point” date you selected for the SOL timing logic (especially if your sheet has multiple possible date fields)
• Whether the target event date you’re comparing against (commonly a filing date, calculation date, or similar checkpoint in your workflow) is more than 4 years after that start date
• Common spreadsheet date errors, such as:

  • Off-by-one problems (e.g., month/year only vs. full dates)
  • Timezone/export mismatches (e.g., local time vs. UTC causing a date shift)

Statutory anchor (default timing used by this checker): N.J.S.A. 12A:2-725, general SOL 4 years.

2) Spreadsheet field mismatches (“right numbers, wrong labels”)

Closing Cost spreadsheets typically depend on multiple fee inputs. The spreadsheet can produce plausible totals even when the inputs are wired incorrectly. A checker should look for issues like:

• Column swaps (e.g., taxes entered in an escrow column)
• Unit mismatches, such as dollars vs. percentages mixed in the same field
• Row alignment errors caused by sorting/filtering (e.g., the fee category moved but the amount didn’t)
• Header/label mismatches where the spreadsheet’s column names don’t match what the calculator expects

Practically, the checker should confirm:

• Date fields are actual dates (not text)
• Money/fee fields are numeric
• Required fee inputs aren’t left blank unless your model explicitly supports defaults (e.g., treating missing values as 0)

3) Incomplete or inconsistent amount components

Closing costs often come from multiple components (for example: lender fees, third-party charges, taxes, prepaid interest). A checker should verify:

• All required components are present, or explicitly set to 0 when appropriate
• No accidental negative values appear (unless the workflow explicitly supports credits)
• Totals reconcile: the sum of components matches the declared subtotal/total cell within a reasonable rounding tolerance (since Excel/Sheets rounding can differ slightly)

This is important because a spreadsheet can still “calculate” while being internally inconsistent—especially after copy/paste edits or re-mapping columns.

4) Rounding and formatting that silently distort totals

Even when all inputs are correct, spreadsheet formatting can alter results:

• Numbers imported as text (so math behaves unexpectedly)
• Commas or locale formats like "1,234.00" vs. 1234.00
• Rounding applied at intermediate steps instead of only at the final total

A checker should enforce consistent behavior such as:

• Converting text-to-number safely
• Standardizing currency formatting
• Applying rounding predictably (commonly: keep full precision through component math, then round the final total)

When to run it

Run the New Jersey SOL-aware spreadsheet check at two points in your workflow: once before calculation and once before output is finalized or shared.

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.

Stage A: Before running the closing-cost calculation

Run it first when:

• You’re importing a new dataset (closing statements, loan estimates, case notes)
• You changed any date fields
• You updated fee categories, mapping, or column logic
• You re-exported or reformatted the spreadsheet

A quick trigger checklist:

Stage B: Immediately before you share the output or docket it

Re-run the checker right before you:

• Export a results report (PDF/CSV)
• Add figures into a case summary or spreadsheet summary
• Attach the output to downstream materials

This second run helps catch “final copy drift,” where the sheet is edited after the first check (even slightly).

Try the checker

Use DocketMath to make New Jersey timing and spreadsheet integrity checks faster and more repeatable.

1. Open the closing-cost workflow in DocketMath.
2. Gather your core fields in one place:

   • The starting date you’re using for SOL timing checks
   • The target date you’re comparing against (often a filing/calculation checkpoint in your workflow)
   • Fee component inputs used by your Closing Cost model
3. Run the checker and confirm it passes:

   • Dates are valid date types
   • Timing comparisons align with the default 4-year SOL rule under N.J.S.A. 12A:2-725
   • Amounts reconcile and rounding is consistent
4. Review the flags (if any) and correct the spreadsheet inputs before exporting results.

If the checker reports issues, fix the spreadsheet inputs and re-run the check rather than forcing the calculator to “make it work.”
