Inputs you need for Alimony Child Support in New Mexico

Inputs you will need

Before you run DocketMath’s Alimony Child Support calculator for New Mexico (US-NM), gather the specific numbers the tool needs to compute support and understand how those numbers drive the results. This is a practical checklist: if you miss an input, the calculator can’t model your situation accurately.

SOL note (timing context only): New Mexico has a general default statute of limitations (SOL) period of 2 years for the claim implied by the general SOL rule in N.M. Stat. Ann. § 31-1-8. If your situation involves a different, claim-type-specific SOL rule, that would control—but no claim-type-specific sub-rule was located here, so this content reflects the 2-year general/default period. This is not a substitute for a claim-type-specific SOL analysis.

Use this checklist as your “data room” for the calculator so you can enter clean, consistent numbers.

Alimony (spousal support) inputs

Child support inputs

Common inputs that affect both alimony and child support

Record-keeping checks

Tip for self-employed or variable income

If income varies from month to month, decide how you’ll represent it before you start entering numbers:

Where to find each input

You don’t need to dig through every document in your case file. Focus on the sources that typically produce the numbers DocketMath asks for.

Input you’ll needWhere to find it (practical sources)What to verify
Monthly gross incomeRecent pay stubs, employer earnings statements, benefits statementsTime unit (monthly vs weekly) and completeness (overtime/bonus/commissions if applicable)
Allowable deductions/adjustments (if prompted)Payroll deductions, child-care invoices, health expense statementsWhether it’s recurring and supported enough to enter consistently
Length of marriageMarriage certificate date + separation date (or filing date, if the tool uses it)Accuracy to the month (years alone can be too rough)
Parenting time / placement splitParenting plan, existing order, time-sharing schedule/calendarThe modeled schedule matches your intended period
Number of childrenBirth certificates / existing court paperworkAvoid double-counting if prior orders exist or if there are children in different arrangements
Existing support orders (if modeled)Existing judgment/order documentsAmounts and start dates (if the tool reflects them)

Tip: confirm “Party A / Party B”

Before inputting the numbers, make sure the person you intend to model as the payor/recipient matches the calculator labels. Mixing them can flip the result structure even if the dollar amounts are correct.

SOL context (why it may matter for timing)

New Mexico’s general/default 2-year SOL period referenced through N.M. Stat. Ann. § 31-1-8 can affect how far back certain claims may reach. DocketMath’s calculator is primarily for support amounts based on scenario inputs, but if you’re comparing “what might be owed” versus “what can be claimed,” timing and documentation still matter.

Reminder: This is general guidance based on a general/default SOL reference. It does not replace an attorney or claim-type-specific SOL analysis.

Run it

Once you’ve collected inputs, you’re ready to run the calculation.

  1. Open DocketMath: Alimony Child Support
  2. Select New Mexico (US-NM) if the tool asks you to confirm jurisdiction.
  3. Enter the inputs using the tool’s expected format:
  4. Review the outputs:
  5. Use “what-if” runs to understand sensitivity:
    • Change parenting time by 10–20% and note how the child support changes
    • Switch to a different representative income month (or average window) if income is variable
    • If a deduction/expense is uncertain, run with and without it and compare results

How outputs typically change when inputs change

Use these expectations to sanity-check results:

  • Higher payor income → higher support
    Because the tool uses income to estimate support capacity, increasing or decreasing monthly gross income typically moves both child support and alimony outputs (when alimony is included).
  • More children → higher child support
    The number of children is a direct driver in most guideline-style formulas.
  • Parenting time balance can change support
    A different custody/placement split may change the amount, depending on how the tool credits each parent’s costs.
  • Marriage length can affect alimony modeling
    Longer marriages often align with different alimony durations/intensity within the tool’s structure.
