How to run Alimony Child Support in DocketMath for Philippines

Step-by-step
This guide walks you through running Alimony + Child Support calculations in DocketMath for the Philippines (PH). The goal is to get you from “I have documents” to “I have numbers” while using jurisdiction-aware rules built into the alimony-child-support calculator.
Note: This is a workflow guide, not legal advice. Use the output as a starting point for discussion or review, especially if your case has special facts (for example: disability, custody arrangements, or support already being paid).
1) Open the correct DocketMath tool
- Go to the primary calculator page: **/tools/alimony-child-support
- Confirm the jurisdiction is set to Philippines (PH).
- If your interface shows a jurisdiction selector, set it to PH so rules, labels, and assumptions match local practice.
2) Gather the inputs DocketMath will ask for
Before entering anything, collect these items (you can estimate some, but document your basis):
- Support type
- Alimony/spousal support (if applicable)
- Child support (for children)
- Income information
- Your monthly gross income
- The other parent’s monthly gross income (or the paying spouse’s)
- Number of children
- Total children covered by the support calculation
- **Living arrangement / custody input(s)
- Whether the child’s care is primarily with you, primarily with the other parent, or shared (use the option that best matches your situation)
- Time period
- Monthly vs annual context (the calculator typically normalizes to monthly output, but follow the tool prompts)
- Other relevant adjustments
- Any special flags the calculator asks for (for example: additional dependents, special circumstances, or deductions—if shown in the UI)
A quick checklist you can follow:
3) Enter income using consistent monthly numbers
DocketMath works best when both sides use comparable income bases.
- If you have payslips: convert to monthly gross (not net) unless the calculator specifies otherwise.
- If income is irregular: use a documented average (for example, last 3–6 months) and enter it consistently for both parties.
How outputs change:
- Higher paying-party income generally increases the support figure.
- Higher receiving-party income often decreases the support need in formula-based systems.
- Mixing different income bases (gross vs net for one party) can skew results significantly.
4) Choose the child-related settings
When the calculator asks about children and custody, make a deliberate choice:
- Number of children: enter the exact count the support claim covers.
- Custody / care arrangement: pick the option that reflects who primarily provides day-to-day care.
How outputs change:
- More children typically increases the total monthly support amount.
- Certain custody options can affect whether the calculation assumes shared vs primary care.
5) Select alimony options (if your scenario includes spousal support)
If your tool includes alimony parameters, choose the option that fits your situation:
- Is this spousal support being calculated on the same month basis as child support?
- Does the calculator separate outputs (for example, “spousal support” vs “child support”)?
How outputs change:
- Alimony output will move based on the incomes you provide and any spousal-support-specific flags the calculator requests.
- If you toggle off spousal support, you’ll see child support only (or a reduced results panel, depending on the UI).
6) Review the computed results panel
After you submit the inputs, DocketMath should display results in a readable structure. Typical outputs include:
- Monthly child support amount
- Monthly alimony/spousal support amount (if selected)
- Totals (where relevant)
- A breakdown table (inputs to computed outputs)
Use the results to sanity-check:
- Does the number scale reasonably with income changes?
- Does the number reflect the number of children you entered?
- Are you seeing monthly amounts consistent with your timeframe?
7) Run scenarios to test “what if” changes
Change one input at a time to see how DocketMath responds:
- Lower or higher paying-party income
- Change custody option (only if your facts truly differ)
- Adjust number of children if you discover you entered the wrong count
Practical approach:
- Keep a note of the current baseline inputs.
- Make one change per run.
- Compare outputs side-by-side.
Pitfall: Don’t “stack” multiple changes between runs. If you adjust income, custody, and children all at once, you won’t know which factor drove the new amount.
8) Export or save your results (if the tool supports it)
If DocketMath offers download, print, or save:
- Export a copy of the results after the final scenario
- Include the jurisdiction label (PH) and the assumptions you selected
This helps when you later review with a case worker or reconcile with documents.
Common pitfalls
Here are the issues that most often produce confusing or incorrect results when running alimony + child support in DocketMath for the Philippines:
- missing a required input
- using a stale rate or rule
- ignoring calendar or holiday adjustments
- skipping documentation of assumptions
1) Mixing gross and net income
- Entering net income for one party and gross income for the other will distort the support output.
- DocketMath generally expects a consistent income basis per party.
✅ Fix: Convert both parties to the same basis (typically monthly gross, unless the tool prompts otherwise).
2) Wrong number of children
Even a one-child mismatch can materially change the computed amount.
✅ Fix: Verify you entered the total children covered by the calculation.
3) Custody/care setting doesn’t match your situation
Choosing “shared” when day-to-day care is primarily with one parent (or vice versa) can affect outcomes.
✅ Fix: Match the selection to who provides primary care in practice.
4) Using mismatched time averages
If one parent’s income is averaged over 1 month and the other over 6 months, comparisons become inconsistent.
✅ Fix: Use a consistent averaging window (for example, last 3 months average for both parties).
5) Updating only one side during scenario runs
You might intend to test paying-party income, but you accidentally also change custody or number of children.
✅ Fix: Run controlled scenarios—one variable change per run.
6) Assuming the tool result includes everything in your full fact pattern
Calculator outputs are driven by the inputs shown in the interface. If your situation includes circumstances not represented in those options, results may not cover your full context.
Warning: If your case involves extraordinary circumstances (for example: special medical needs, disability, or existing arrangements not captured by the tool options), the calculator output may not fully reflect those facts.
Try it
Ready to see how the Philippines (PH) workflow looks with your own numbers? Use DocketMath here: **/tools/alimony-child-support
Quick “try this” plan (10 minutes):
- Enter PH jurisdiction (confirm it’s set).
- Start with baseline assumptions:
- Paying party monthly gross income: use your best available figure
- Receiving party monthly gross income: same approach
- Number of children: exact count
- Custody option: pick the closest match to reality
- Run once and review the results panel.
- Make one controlled change:
- Example: increase paying-party income by 10% and rerun
- Compare the output change and confirm it behaves logically.
