For California probate and trust & estate attorneys

Procedural automation for the work that moves through probate court

Percheron fills your Judicial Council forms, drafts the notices and declarations each matter calls for, tracks every procedural deadline, and answers questions about your case file — with every output cited to its source and yours to approve.

The Problem

Every case triggers the same forms, the same boilerplate filings, the same proof-of-service documents. It's the work attorneys hate doing — and the work that erodes margins and morale.

30–50% of your day goes to procedure

Court forms, proofs of service, and routine declarations are repetitive, exacting, and a constant drain on the hours you'd rather spend on clients.

One missed date is malpractice exposure

Hearing dates, notice and service windows, and statutory deadlines — creditor-claim periods, inventory and appraisal, accountings — all run on the probate clock, and a single missed deadline carries real consequences.

General AI can't be trusted with this work

Horizontal AI tools invent facts and give you no way to check them against your file — a non-starter when the work is court-facing and the record has to hold up.

What Percheron Does

Four capabilities that absorb the procedural work — without ever inventing a fact.

01

AI Form Filling

Auto-populates Judicial Council forms (DE-111, GC-310, and more) from your matter documents. Every field traces back to the source passage it came from.

e.g. DE-111, GC-310, and more
02

Document Generation

Drafts the notices, declarations, demand letters, and proofs of service a matter calls for — with inline citations on every assertion.

Notices, Declarations, POS, Letters
03

Procedural Deadline Tracking

Surfaces and tracks each matter's procedural clock — hearing dates, notice and service windows, and statutory deadlines like creditor-claim periods, inventory and appraisal, and accountings. Every date is surfaced for your review, so nothing critical slips past you.

Why We Win

Form-Specific Tooling, Not Generic AI

Built around the actual court forms and procedural documents attorneys file every day. Horizontal AI platforms have no incentive to build per-form, per-jurisdiction infrastructure. We do.

Closed-World by Design

Every AI action is constrained strictly to the documents in your matter — not the general internet. We don't infer or invent solutions; we work only from your record.

Citation-Backed Field Values

Every filled field links to the exact source passage it was extracted from. Attorneys review before anything is dispatched. Full audit trail.

Built Natively on California Probate Procedure

The Judicial Council forms, the local rules, and the statutory clocks of probate court. The depth a horizontal AI tool has no reason to build.

Multi-Tenant Security

Matter-level access control and audit logging built for real law firms. Your clients' data stays in your matter. Always.

Built For

Built for California probate and trust administration — and the estate planning and elder law matters that run through probate court.
