Inputs you need for Alimony Child Support in Brazil

Inputs you will need

Run this scenario in DocketMath using the Alimony Child Support calculator.

To run DocketMath’s alimony-child-support calculator for Brazil (BR), gather the core financial and case details below. Most results (and any suggested ranges) depend directly on these inputs—especially income, child-related costs, and who spends time with the child.

Gentle disclaimer: This is for planning and preparation. It isn’t legal advice, and it won’t capture every factor a Brazilian court may consider in your specific case.

Use this checklist to collect everything in one place before you start:

Where to find each input

DocketMath is designed to be jurisdiction-aware for Brazil, but the practical part is gathering the underlying facts from your case file, payroll, and day-to-day records.

Here’s where you can pull each input:

Most inputs live in the case file, contracts, or docket entries. Dates usually come from the triggering event notice; rates and caps come from governing documents or statute; and amounts come from the ledger or judgment. Record the source for each value so the run is reproducible.

1) Income inputs

• Payer income

  • Payslips (holerites) for salary and employer-reported components.
  • Tax/accounting summaries if self-employed.
  • Bank statements for income that isn’t reflected consistently in payslips.
• Recipient income

  • Often from income statements, payslips, employment declarations, or reliable records used in filings.

Tip: If income fluctuates, use the figure you can defend as representative (for example, an average of the most recent months).

2) Child-related recurring expenses

Look for typical monthly totals for categories like:

• School bills (monthly tuition, tutoring, fees)
• Healthcare invoices (insurance premiums, therapy sessions, recurring prescriptions)
• Childcare receipts (daycare/after-school invoices)
• Transportation estimates (monthly transit or documented travel costs)
• Extracurricular statements (sports clubs, lessons)

If you don’t have invoices for every item, you can still enter a reasonable monthly estimate—just stay consistent with what you can later support.

3) Custody/time-sharing inputs (and where expenses occur)

• The parenting arrangement in the agreement or filings.
• Any schedules showing which parent provides day-to-day care.
• A simple “expense map”: which parent typically pays the major child costs.

4) Existing support obligations

Gather orders or settlement documents that mention:

• current alimony/child support payments,
• the recipient(s),
• and the amounts.

5) Case context inputs

• Where the case is filed (city/state), so DocketMath can apply Brazil-specific jurisdiction-aware assumptions and present results in a usable way.
• Whether you’re modeling:

  • child support,
  • spousal/partner support,
  • or a combined scenario.

Run it

After you compile the checklist items, you can run DocketMath quickly—then validate how sensitive the results are to each input.

Step-by-step workflow in DocketMath

1. Open the tool at: /tools/alimony-child-support
2. Select the relevant scenario:

   • Child support, alimony, or both (if your setup includes both).
3. Enter:

   • payer and recipient income figures,
   • the number of children,
   • recurring child expense categories (monthly),
   • custody/time-sharing inputs (if applicable),
   • and any existing support obligations.
4. Review the output:

   • expected monthly support figure(s),
   • the way the model weights income vs. child costs,
   • and any category breakdown shown on your results screen.
5. Do a quick sensitivity check:

   • Change one major variable (for example, healthcare cost or custody split) and re-run.
   • If the estimate jumps a lot, re-check that particular input.

How output changes when inputs change (sanity-check guide)

• Payer income increases: support estimate typically increases because the payer’s capacity rises.
• Child costs increase (education/healthcare): the model may increase support even if income stays the same, because child needs are higher.
• Recipient income increases: support estimate often decreases relative to the baseline, since the recipient’s capacity rises.
• Existing support obligations increase: reduces what the payer can allocate to the current case, often lowering the estimate.
• Custody/time-sharing shifts: may alter how expense burden is assigned, which can affect the monthly figure.

Quick checklist before you finalize results

When your inputs are consistent, you’ll get results that are easier to compare against your budgeting needs and your case documents.
