Worked example: Alimony Child Support in New Mexico

Example inputs

Below is a worked example showing how DocketMath can estimate alimony and child support calculations in New Mexico (US-NM) using jurisdiction-aware defaults. This walkthrough is for understanding; it’s not legal advice.

Here is a simple illustration for New Mexico. These values are for demonstration only and should be replaced with your actual inputs.

  • Principal or amount: $100,000
  • Rate or cap: 10%
  • Start date: 2025-01-15
  • End/as-of date: 2025-09-30

Scenario (New Mexico household)

Assume these facts for the monthly calculation:

InputValueHow it affects the result
Date of calculation2026-04-15Used to anchor the run; doesn’t change the numbers directly.
Parents’ gross income (payer)$6,500/monthHigher payer income generally increases support obligations.
Parents’ gross income (recipient)$3,000/monthHigher recipient income generally reduces support obligations.
Number of children2More children generally increases the support amount.
Child-related expenses (inputs to the calculator)Included per DocketMath modelThese adjust the child-support portion.
Alimony / spousal supportEnabledTurns on the alimony component (if your DocketMath run supports it).
Alimony duration assumption24 monthsUsed only as a modeling assumption inside the calculator run.

Statute-related note used in this example (SOL reference)

DocketMath also surfaces litigation timing context. For New Mexico, the general statute of limitations (SOL) period referenced in the jurisdiction data is:

  • 2 years (general/default)
  • Authority: N.M. Stat. Ann. § 31-1-8

Important: No claim-type-specific sub-rule was found. That means this example uses the general/default SOL period as the baseline and does not attempt to apply a narrower period for particular claim types.

Note: If a specific claim type has a different SOL than the general rule in N.M. Stat. Ann. § 31-1-8, that narrower period would control for that claim.

Example run

Use DocketMath’s alimony-child-support calculator for this scenario. If you want to run the exact same tool, start here:

Run the Alimony Child Support calculator using the example inputs above. Review the breakdown for intermediate steps (segments, adjustments, or rate changes) so you can see how each input moves the output. Save the result for reference and compare it to your actual scenario.

Example step-by-step (what you’d enter)

  1. Open /tools/alimony-child-support
  2. Select **Jurisdiction: New Mexico (US-NM)
  3. Enter the scenario values:
    • Payer gross income: $6,500/month
    • Recipient gross income: $3,000/month
    • Children: 2
    • Turn on alimony in the tool
  4. Run the calculation

Output you should expect to see

DocketMath typically returns a breakdown such as:

  • **Child support estimate (monthly)
  • **Alimony estimate (monthly)
  • Total estimated monthly obligation (child support + alimony)
  • Timing / SOL context using N.M. Stat. Ann. § 31-1-8 (general 2-year baseline)

Because this is a worked example, the exact numeric outputs depend on the internal modeling assumptions embedded in the tool. For illustration, assume the run produces:

Output categoryEstimated monthly amountWhat it means in the model
Child support$1,450Driven primarily by incomes and number of children
Alimony$650Driven by enabled alimony assumptions and income differential
Total obligation$2,100Sum of child support + alimony components

SOL timing context surfaced by the tool

DocketMath’s jurisdiction-aware summary includes the general SOL period:

  • General SOL: 2 years
  • Citation: N.M. Stat. Ann. § 31-1-8

If you’re using the tool as part of planning (for example, when reviewing possible timing for actions), treat this as a general baseline unless you have reason—based on claim type—to override it.

Pitfall: Using the general 2-year SOL from N.M. Stat. Ann. § 31-1-8 when a different SOL applies to a specific claim type can skew planning and risk timelines.

Quick sanity check against the inputs

Even without changing any numbers, you can confirm directional correctness:

  • Payer income ($6,500) is higher than recipient income ($3,000) → support obligation typically increases.
  • Two children → child-support portion is higher than it would be with one child.

These checks help confirm the scenario is entered as intended.

Sensitivity check

Now let’s see how changing a single input affects the estimated results. The point is to understand which levers move the monthly figure most—not to treat the estimates as legal determinations.

To test sensitivity, change one high-impact input (like the rate, start date, or cap) and rerun the calculation. Compare the outputs side by side so you can see how small input shifts affect the result.

Change 1: Increase payer income by $1,000/month

  • New payer income: $7,500/month (recipient stays $3,000)
  • Children remain: 2

Expected directional impact

  • Child support: up
  • Alimony: up (if alimony is enabled and depends on income differential)
  • Total obligation: up

**Illustrative outcome (for understanding)

CategoryOriginalAfter change
Child support$1,450$1,700
Alimony$650$800
Total$2,100$2,500

Change 2: Reduce children from 2 to 1

  • Payer income stays $6,500
  • Recipient income stays $3,000
  • Children: 1

Expected directional impact

  • Child support: down
  • Alimony: may change less than child support, depending on how the tool models alimony relative to dependent status (some models treat child count as an indirect factor)

Illustrative outcome

CategoryOriginal (2 kids)After change (1 kid)
Child support$1,450$950
Alimony$650$600
Total$2,100$1,550

Change 3: Turn off alimony

  • Keep incomes and children as in the original scenario
  • Disable alimony in DocketMath

Expected directional impact

  • Child support: same (in most models that isolate alimony)
  • Alimony: $0
  • Total: down

Illustrative outcome

CategoryOriginalAfter change (no alimony)
Child support$1,450$1,450
Alimony$650$0
Total$2,100$1,450

Timing context sensitivity (SOL baseline)

This example’s SOL reference is anchored to:

  • N.M. Stat. Ann. § 31-1-8
  • General SOL period: 2 years

Because this “2 years” value is a baseline jurisdiction timing input, it generally doesn’t change when you modify incomes or child count—those changes affect support estimates, not the general SOL baseline.

Warning: DocketMath’s SOL display reflects the general/default rule. If you’re evaluating a specific claim, verify whether a narrower SOL applies rather than relying on the general 2-year rule.
