Illustrative distribution of time-to-resolution across comparable federal civil matters, with an 80% prediction interval shaded.
One model · the whole decision

Not just when a case resolves.
Whether the capital comes back, and what it does to the book.

Duration
Time to resolution per case, as an 80% interval whose measured coverage is published — not a point guess.
Disposition
How it ends: settlement, dismissal, judgment, or transfer — forecast, not assumed.
Capital at risk
The dismissal rate is your loss probability. Read per case type from millions of dockets.
Portfolio economics
Per-case distributions roll into IRR, capital lockup, recycling, reserves — and a quarterly cash-flow calendar with honest bands.
Underwriting
What a new case does to the book's IRR — before a dollar is committed. Your own covenant rules can fail a candidate outright.
Aging alerts
Every open case tracked against its own forecast — what's aging out of band flags in the book and lands in the weekly capital brief.
Benchmarked to the courts
Cross-checked against the judiciary's own published statistics, within a fraction of a month.
Auditable calibration
Every forecast ships with its own out-of-sample error record. No black box.

Timing is the engine. Everything above is what it drives. Tertius forecasts timing and disposition — never merits or damages.

01 — The clock

Every case has a clock.

Capital isn't committed indefinitely — it's committed until a case resolves, and that timeline determines when it returns, when it can be redeployed, and how a portfolio performs. Tertius makes it measurable.

Tertius forecasts where that point lands.
Capital stays committed until the case resolves—Tertius prices when it's likely to come back.
02 — The ending

Duration is only half the forecast.

A three-year case isn't one forecast — it may settle, transfer to MDL, or end another way entirely. Tertius forecasts both the timeline and the path.

The same case ends many ways. Tertius forecasts each.
Disposition and timing, forecast together—so a transfer at three months and a settlement at three years are priced as the different outcomes they are.
03 — Capital at risk

The question isn't when.
It's whether your capital comes back.

A dismissal is a loss. A settlement is a return. Tertius reads the odds of each from millions of resolved dockets, so the ending is priced before a dollar goes in.

04 — The filing

The forecast begins on page one.

The complaint already carries measurable signals — jury demand, class allegations, pro se litigants, district selection. Read at filing, before the first scheduling order is entered.

05 — Time is money

Time is part of the risk.

The same payoff, earned later, is a lower return.

Timing isn't an operational detail.

It's a financial variable.

06 — Portfolio impact

Plan capital with time in mind.

Cases don't move independently. Portfolios fail together. Courts slow together. Settlement behavior shifts together. Doctrine ripples through a book at once.

The operating ritual

Open every capital meeting with it.

The analysis wins the first meeting. The ritual wins the renewal: the brief that opens Monday, the sheet on the projector, the journal of what you decided, and the covenants standing guard in between.

The weekly capital brief
Fund plan
Lockup, aging criticals, covenant flags, and suggested reserve adds — emailed Monday morning to the principals who never log in. It forwards.
Meeting mode
All plans
One clean URL for the projector: the lockup sheet and the decision journal, nothing else. Open every capital meeting with it.
The decision journal
All plans
“Tightened the line rule to 48 months p90” — dated, append-only, stamped with the model version it was decided under. The record your LP letter quotes.
Covenant checks
Fund plan
State a fund-life, credit-line, or reserve rule once and every capital view is graded against it. A block rule fails a candidate in underwriting before a dollar moves.

Starter carries the sheet and the journal; Fund adds the watch — alerts, covenant checks, underwriting gates, and the weekly brief. See what sits in each plan →

07 — The model

Built from outcomes.
Measured against reality.

Every forecast is grounded in real federal civil cases. Every model is graded on held-out cases it never saw during training. Performance isn't estimated—it's published.

Docket-average baseline: a single constant prediction (the training set's own unconditional median — no case-type, district, or amount signal), scored on the identical held-out cases with the identical rules. Not a strawman — it's what "use last year's docket average" gets you.
New in Tertius Acta 6Same forecasts as Acta 4 — this release upgrades the scorecard, not the model
01
Raw fixed-band coverage published beside the served band — a denominator the band recalibration cannot shrink, per case type
02
A rolling-origin score of the deploy pipeline on 570,530 unseen 2024+ filings, so the newest regime is graded too
03
No silent gaps: every case type appears in the calibration table, and cells too thin to score say so instead of showing a percentage
78 of every 100 outcomes fell inside the predicted 80% interval.
Measured on 408,120 held-out cases where follow-up already covers the predicted range — still-open cases included, never dropped.

Every release includes:

Historical training data
Held-out validation
Calibration against federal court statistics
Stress testing against systemic slowdowns
Version history for reproducibility

Reproducible, versioned, and open to inspection.

The flywheel

Graded on your own book.

Everyone gets the same public-record model. Only you see it scored against your cases.

01
Public record is the model
Every forecast comes from a model trained exclusively on public federal dockets — 9.1M cases, no customer data inside it.
02
Your outcomes grade it
Each outcome you record scores Tertius against your own realized results, out of sample — accuracy on your book, not a vendor average. Your outcomes don't train the current model.
03
Milestones, disclosed
Recorded outcomes count toward future recalibration milestones. If a future model version trains on customer-contributed outcomes, its calibration page will say so before it ships — and captions, parties, and amounts never leave your organization.

And you can see it working: every forecast is graded against your own realized outcomes, out of sample — the accuracy number no in-house spreadsheet can produce.

08 — Trust & control

No black boxes, no invented milestones. Just duration forecasts you can reproduce and defend.

09 — FAQ

Fair questions.

The ones skeptics ask first — answered the way everything on this page is answered.

Why not just use the average time to resolution?

Because the risk lives in the spread, not the middle. Cases of the same type resolve anywhere from under two years to past fifteen, and the median itself moves by multiples with court, claim, and amount. Published averages also count only closed cases — the slowest cases are still open, so the average can't see them. Tertius forecasts the full distribution, counts every case, and updates the forecast as a case ages.

Case length depends on attorney strategy. What does a timing forecast actually mean?

A calibrated range, not a theory of the case. Twenty years of real dockets already contain every delay tactic and settlement posture attorneys actually use — the forecast is the distribution those behaviors produce. A life table prices lifespan without knowing anyone's story. This is the same discipline, applied to dockets.

Does a longer case mean a worse outcome?

No — it means a worse return on the same outcome. The same recovery, arriving two years later, can cut annualized return in half, and capital locked in one case can't fund the next. Duration is a financial variable, independent of merits. Tertius forecasts the clock; the merits stay yours.

How is the model graded?

Out of sample, on more than a million held-out cases the model never saw in training — still-open cases included, never dropped. The scorecard above is live, every forecast ships with the error record of the model that produced it, and the underlying data is cross-checked against the federal judiciary's own published statistics.

Which courts does it cover?

Federal civil, by design. Patent, antitrust, securities, and MDL mass torts live in federal court — and so does most of the capital deployed against them. Every case in the dataset is a real federal docket.
