Step-by-step
This is a practical walkthrough for running Alimony + Child Support calculations in DocketMath for New Mexico (US-NM) using the alimony-child-support calculator. This guide focuses on workflow and jurisdiction-aware settings—not legal advice.
- Select New Mexico in the Alimony Child Support tool.
- Enter the trigger dates and any caps or rates.
- Run the calculation and save the output.
1) Start the right calculator
- Open DocketMath and go to: ** /tools/alimony-child-support
- Confirm you’re using the New Mexico jurisdiction (US-NM). If DocketMath offers a jurisdiction selector, set it to US-NM before entering numbers so the jurisdiction-aware rules apply.
2) Identify which amounts you’re calculating
The alimony-child-support calculator is typically used to model:
- Child support (support for children)
- Alimony/spousal support (support between spouses)
If your case involves only one of these, you can still run the calculator—just be consistent about which inputs you provide so your outputs reflect what you intend to estimate.
3) Enter the core case inputs
Enter inputs in the order the DocketMath UI presents them. While the exact fields can vary, the calculator commonly relies on categories such as:
- Parent/household income fields
- Number of children
- Parenting-time / custody-related inputs (if prompted)
- Allowances, offsets, or relevant adjustments (if prompted)
Tip (to reduce mistakes): If you’re unsure which income items go into a specific field, start by putting your best available numbers into a single, consistent income category (for example, “gross income” if the UI asks for gross). Then compare how the results change as you refine your entries.
4) Review how jurisdiction-aware rules affect results
After you enter values, DocketMath applies the US-NM rule set. For New Mexico, this includes timing-related legal assumptions tied to the jurisdiction’s general statute of limitations settings.
Statute of limitations reference (general/default)
New Mexico’s general statute of limitations period is 2 years, under:
- N.M. Stat. Ann. § 31-1-8
Important: No claim-type-specific statute of limitations sub-rule was provided in the jurisdiction data. So this guide uses the general/default 2-year period from N.M. Stat. Ann. § 31-1-8 rather than assuming any specialized limitations rule.
5) Run the calculation and interpret the outputs
Click Calculate (or the equivalent action). Then review the results sections:
- A child support result area (often monthly)
- An alimony/spousal support result area (often monthly)
- Any assumptions summary explaining which inputs the calculator used
How outputs change when you adjust inputs
Use a quick “what-if” workflow:
- Change income inputs → the support amounts typically change because the income base is recomputed.
- Change number of children → child support output typically changes directly.
- Change parenting-time/custody inputs → child support output may change if your UI enables parenting-time weighting logic.
If DocketMath includes an “explainer” panel or intermediate breakdown, check it to confirm the tool is applying what you expect for US-NM.
6) Sanity-check with quick comparisons
Before relying on any numbers for decisions, validate your inputs with consistency checks:
- Are both parties’ incomes entered in the correct direction/field?
- Does the number of children match your case?
- If parenting time is included, do those inputs match the basic schedule you’re modeling?
A strong approach is to run two scenarios:
- Scenario A: your best estimate of inputs
- Scenario B: a reasonable alternative (for example, slightly different income or time-sharing)
If results change dramatically without corresponding input changes, stop and review your entries.
7) Save or export results (if available)
If your workflow supports it, consider saving/exporting your runs (PDF/screenshot) so you can:
- Keep track of what inputs you used
- Compare scenarios side-by-side later
Common pitfalls
Support calculations are sensitive to inputs and to timing-related assumptions that can affect procedural posture. Here are common issues to watch for when using DocketMath for New Mexico.
This guide uses the general 2-year statute of limitations under N.M. Stat. Ann. § 31-1-8.
If a claim-type-specific limitations rule applies to your exact filing category, the appropriate period could differ—but that specific rule was not provided in the jurisdiction data here.
Entering net where the UI expects gross (or vice versa) can significantly distort the calculated results.
Keep the same “gross vs. net” approach consistent for both parties.
Many calculators treat this as a direct scaling factor.
If the children count changes, rerun the scenario rather than adjusting only another field.
Small changes can affect outputs if parenting-time weighting is enabled.
Use a consistent schedule representation across runs.
DocketMath won’t infer facts you don’t enter. If a rule expects an input and you leave it blank, the tool may use defaults or assumptions that don’t match your situation.
Warning: Don’t treat calculator outputs as legal conclusions. Use them as structured estimates to understand how inputs affect results, then align your final filings with the controlling documents and any applicable statutes.
Try it
- Open the tool here: ** /tools/alimony-child-support
- Select or confirm New Mexico (US-NM).
- Enter your best estimates for:
- Income figures for the relevant parties
- Number of children
- Any parenting-time/custody inputs requested
- Run the calculation.
- Do one controlled “what-if” test:
- Change one input (such as income or parenting time) by a small, realistic amount
- Re-run and observe how child support and alimony results shift
To keep your workflow organized, you can track runs like this:
| Run | What you changed | Expected impact | What you observed |
|---|---|---|---|
| A | Baseline inputs | Baseline support amounts | |
| B | Income changed | Support should move accordingly | |
| C | Children/time changed | Child support may change |
When reviewing results, remember the timing framework used in this guide: New Mexico’s general SOL is 2 years under N.M. Stat. Ann. § 31-1-8, because no claim-type-specific SOL rule was provided.
