01 · The engine

The schedule is the law. So we parse it verbatim.

Each jurisdiction's guideline schedule is lifted row-for-row from the code — never approximated with a formula. The engine that reads it is pure, extracted, and locked by a statutory test suite: worked examples from the guidelines, edge cases at the bands, and a parity case that reproduces the printed arithmetic to the dollar. When a test fails, we don't ship.

Income shares round to a tenth of a percent, and the rounded value drives all downstream math — so the worksheet you print reproduces its own arithmetic when opposing counsel checks it by hand.

02 · The worksheets

Every line item. Every credit. Every band.

Primary and shared custody, side by side — with the details that decide real cases handled correctly: the graduated adjustment bands just past the shared-custody threshold, the cap that keeps a shared-custody order from exceeding the primary-custody amount, direct-pay credits for health insurance and childcare, pre-existing support, and the newest multifamily adjustments.

Above the guideline cap? Aequitas flags it and shows the extrapolation, so the discretionary conversation starts from a defensible floor.

03 · Alimony

Needs-based and percentage — argued from both ends.

The top-down framework builds from the recipient's budget: needs, less resources, capped by the payor's capacity. The bottom-up benchmarks give you the percentage rules of thumb and duration heuristics the other side will bring. Aequitas computes both, shows where they land relative to each other, and flags the disparity arguments that support indefinite awards.

Alimony is computed first and flows into the support calculation automatically — the ordering the statute requires, easy to get wrong by hand.

04 · The output

What you print is what the clerk expects.

Worksheets follow the official court-form layouts, with the children's names and the case caption where the court wants them. One click prints to PDF; another exports an editable Word document with tables, borders and widths intact — so the memo you send opposing counsel is the memo you actually formatted.

Behind every document: matters with autosave, named scenario snapshots, and an audit trail of every change since intake.
