Citation Verification Agent for Sydney Estate Planning Lawyers: Verify Authorities Before They Reach a Supreme Court Probate List

You’re finalising submissions for a contested estate matter — a family provision claim, a construction summons, or an application to pass accounts. The draft cites a handful of authorities on testamentary capacity, the Succession Act 2006 (NSW), and a line of cases on undue influence. Part of it was tightened by an AI tool over the weekend. The hearing is Monday. Somewhere in the document there could be a case name that doesn’t resolve, a paragraph reference that points to the wrong judgment, or an authority assigned to the wrong court. Under the Australian Solicitors’ Conduct Rules, the obligation to be candid with the court doesn’t bend because a model wrote the footnote. The Citation Verification Agent is built to catch this class of failure before lodgement.

The problem

Estate work in NSW runs through the Supreme Court’s Equity Division — probate, family provision, trust construction — and the volume of cited authority per matter is high. A typical contested family provision submission cites foundational cases on the Succession Act 2006 alongside more recent appellate authority, plus statutory references. When parts of that drafting are produced or “polished” by a generative model, citation hallucination becomes a live risk: plausible-looking case names that don’t exist, real cases attributed to the wrong court or year, or invented paragraph numbers within real judgments.

The Australian Solicitors’ Conduct Rules apply regardless of how the citation got into the draft. Rule 19 obliges a solicitor to be candid with the court and not to mislead it — which extends to fictitious or misattributed authorities. Rule 4 (fundamental ethical duties) and Rule 30 (relations with other practitioners) are also implicated when an opponent or the bench has to chase down a citation that resolves to nothing. Manual verification at the pace of a contested probate list — or while juggling a conveyancing file, a will-execution appointment and an enduring power of attorney — is not realistic for any document of meaningful length.

What the Citation Verification Agent does

The Citation Verification Agent is the core feature of RuleCheck by Exegesis — a local-first, deterministic, no-external-LLM pre-lodgement filing checker for Australian legal teams. It accepts a draft (.txt or .md), extracts every cited authority, and checks each one against an Australian authority registry covering the High Court, Federal Court, Federal Circuit and Family Court, State Supreme Courts (including the Supreme Court of NSW) and AustLII. Each citation comes back with a status — verified, mismatched (wrong court, year, or paragraph), or not found — and a recommended action.

The agent does not generate new legal content, does not transmit your draft to any external LLM, and does not retain content beyond the configured retention window. That narrowness is the trust posture: it does one job, deterministically, and produces an artefact you can file with the matter.

How it works

  1. Export the draft submission, affidavit, or written outline as .txt or .md.
  2. Upload it through the RuleCheck web interface (live in beta at rulecheck.onrender.com).
  3. The agent extracts every citation pattern and queries the authority registry deterministically — no model inference, no external API calls on your text.
  4. A structured readiness report is returned: each citation listed with its verification status and a recommended action (re-verify against AustLII, replace, remove).
  5. The report is saved as Markdown and can be archived alongside the matter file, with an optional audit log entry for governance.

For documents under 10 pages, processing typically completes within seconds to a minute.

Why this matters in Sydney

Sydney estate practice sits inside the Legal Profession Uniform Law jurisdiction, which has applied in New South Wales since 1 July 2015. The ASCR took effect in NSW under that framework as the Legal Profession Uniform Law Australian Solicitors’ Conduct Rules 2015. For a Sydney estate planning lawyer, the candour obligations in the ASCR are not aspirational — they are the binding professional conduct rules under which the Office of the Legal Services Commissioner and the Council of the Law Society of NSW assess complaints. A misattributed authority in a family provision submission to the Equity Division is a problem regardless of whether the solicitor typed it or a model produced it.

The Law Council’s 2026 review of the ASCR — including proposals tied to the AML/CTF regime that commences 1 July 2026 for solicitors providing designated services — also signals tighter scrutiny of the systems solicitors rely on. A defensible, auditable pre-lodgement check on every citation is a sensible baseline as those expectations evolve.
