How we research and verify each state's formula
Each state page cites the official government or judicial-branch source for that state's guideline formula (statute number and agency link, visible in the "Methodology & Source" section of every state page). Before a state page is published, we:
- Identify the state's formula model (percentage of income, income shares, or Melson) from the official statute or judicial-branch guideline document.
- Transcribe the exact guideline percentages, schedule tables, income caps, and adjustment rules from that primary source — not from third-party summaries.
- Run 2-3 test scenarios through our calculator and cross-check the output against the state's own official calculator or worksheet PDF, logging the result, the delta, and the verification date.
- Record a "last verified" date and guideline version on the page, and re-check top-traffic states on a recurring basis as guidelines change.
We do not employ or claim review by a licensed attorney. This is a data-verification process, not legal review — see our disclaimer on every calculator page. If you need legal advice, consult a family law attorney licensed in your state.
