Legal Professional Privilege: Advice and Evidence

What Legal Professional Privilege Protects

Advice privilege protects confidential material created for the dominant purpose of obtaining or providing legal advice. Litigation privilege concerns legal services for existing or reasonably anticipated proceedings. Confidentiality is required, but a promise to keep information private does not by itself establish privilege.

The applicable law depends on the court and the process. In federal courts, sections 118 and 119 of the Evidence Act 1995 (Cth) govern client legal privilege when evidence is adduced. Section 118 addresses legal advice. Section 119 covers confidential communications or documents prepared for the dominant purpose of professional legal services for proceedings involving the client, including anticipated proceedings.

Federal pre-trial discovery generally involves the common law. Some state evidence statutes extend privilege provisions to pre-trial production. Identify that distinction before applying a section number across jurisdictions. The Australian Government Solicitor’s privilege briefing explains the different operation of the Commonwealth and state regimes.

In Esso Australia Resources v Commissioner of Taxation [1999] HCA 67, the High Court adopted the dominant-purpose test at common law. The legal purpose must predominate when the communication is made or document prepared. Copying a lawyer into ordinary business correspondence does not establish that purpose.

A confidentiality agreement controls how a recipient handles information. Privilege provides a basis to resist compelled disclosure where its requirements are met. A “privileged” heading records a claim, without deciding whether the claim succeeds. Protection for without-prejudice settlement negotiations involves a separate rule.

NSW, Queensland and Victoria

Select the forum and the disclosure process before choosing the test. A document created in Queensland can be sought in a NSW proceeding. The place of creation alone does not decide which evidence statute applies.

Forum	Advice and litigation privilege	Production check
NSW courts applying the Evidence Act 1995 (NSW)	Sections 118 and 119 apply the statutory dominant-purpose requirements.	Section 131A extends the privilege provisions to specified disclosure requirements, including pre-trial production.
Victorian courts applying the Evidence Act 2008 (Vic)	Sections 118 and 119 protect qualifying confidential advice and litigation material.	Identify the applicable statutory disclosure extension and the court’s production procedure.
Queensland state civil proceedings	Apply common-law legal professional privilege, including the dominant-purpose test.	Check the particular court’s production rules and any statutory modification. Commonwealth section numbers do not become Queensland provisions.

The NSW Judicial Commission’s privilege chapter explains the NSW statutory extension. The Victorian Government Solicitor’s discussion distinguishes common-law protection from Victoria’s statutory protection in court processes. Federal proceedings follow the federal framework described above, including when heard in one of these states.

For a particular communication, identify whether the lawyer acts in a professional legal capacity. Routine commercial advice from an employed lawyer does not acquire protection merely because its author is a lawyer. A label such as “subject to legal professional privilege” cannot supply a missing legal purpose or confidentiality.

Public interest immunity concerns a separate public-harm basis for withholding material. It does not determine whether a client’s legal communications attract privilege.

Litigation Privilege and Third-Party Analysis

A third-party financial report can attract litigation privilege when it meets the confidentiality and dominant-purpose requirements for existing or reasonably anticipated litigation. A general possibility of a future dispute is insufficient to treat every investigation as litigation preparation.

Record why the lawyer commissions the analysis and the proceeding it supports. For example, instructions might seek an account of transfers to help the lawyer advise on an estate recovery claim. A routine annual reconciliation prepared for administration has a different purpose. If both purposes exist, assess which predominates using the circumstances at creation.

The following fictional materials illustrate separate assessments.

Material	Purpose to examine	Privilege assessment
Original bank statement	Bank’s record of account activity	Sending it to the lawyer does not change the original’s character.
Existing factual ledger	Ordinary bookkeeping or administration	Assess the original purpose independently of its later use in litigation.
Newly commissioned analysis	Assisting legal services for a particular dispute	Assess confidentiality, the litigation circumstances and dominant purpose.
Lawyer’s instructions	Obtaining analysis needed for legal advice or litigation	Assess what the instructions communicate and why they were made.

A factual ledger is not automatically outside privilege merely because it contains facts. A new document may satisfy the test, while the underlying transactions remain facts capable of proof from other records. A selected copy or compilation can also require its own assessment if it reveals the legal adviser’s work.

FinTrace saves professional teams hours of statement review by producing a searchable ledger and a findings report. Findings cite the source PDF filename and page, so the evidence is at hand. When commissioning that work, the lawyer records the legal purpose and controls distribution. The service provider’s name and the output’s file format do not determine privilege.

Waiver and Material Shared With Others

Waiver can arise when the client acts inconsistently with maintaining the confidentiality that privilege protects. In Mann v Carnell [1999] HCA 66, the High Court explains that context governs the inconsistency inquiry. Controlled disclosure to a third party can preserve privilege when its circumstances remain consistent with the protected confidentiality.

Circulating a report to support a commercial decision can raise a different issue from sharing it confidentially for the legal task. Relying on selected advice or report conclusions to justify a position can put the supporting context in issue. A statement that the client “does not waive privilege” does not settle the effect of that conduct. Section 122 of the Commonwealth Evidence Act addresses consent and inconsistent conduct where the statute applies.

Consider this fictional distribution list for an estate dispute.

Proposed recipient	Reason for access	Action before sharing
Instructing solicitor and counsel	Advising on the recovery claim	Keep access within the legal task and record recipients.
Retained forensic accountant	Analysis needed for that legal task	Record the role, confidential purpose and authorised access.
Executor’s general administration team	Routine estate administration	Ask the lawyer to assess whether the full report is needed and the waiver consequences.
Beneficiaries or an outside adviser	Explaining or defending the executor’s conduct	Obtain the lawyer’s review before sharing conclusions or attachments.

These are review prompts, not recipient-based guarantees. Record what was disclosed and the purpose of disclosure. A shared professional interest or confidentiality undertaking alone does not resolve every waiver question.

AI services and confidentiality

Before uploading instructions or commissioned analysis to an AI service, identify every recipient that can access the material. Read the applicable service terms for retention, training or other reuse, human access and onward processing. Establish which settings and contractual restrictions apply to the actual account. A confidential intention does not control a recipient’s contractual rights.

The Queensland Law Society’s AI guidance applies confidentiality and privilege concerns to AI processing. Decide whether the proposed disclosure remains consistent with maintaining privilege and whether the client has authorised it. Record the decision before sending the material. An AI service’s name alone establishes neither protection nor waiver.

Assess the contents of the upload separately. An original bank statement retains its underlying character. Instructions explaining the lawyer’s strategy or an analysis commissioned for a legal purpose can raise different privilege issues. Removing names alone might leave protected advice or identifying facts in the file. If the proposed terms permit disclosure inconsistent with confidentiality, keep that material outside the upload.

Review Production and Record the Claim

Before production, assess each document and record the factual basis for any privilege claim without revealing the protected advice. Keep the privilege review separate from the wider financial discovery process in civil litigation.

Use a review record with enough information to explain the decision.

1. Identify the document by a stable reference and record its date, author and recipients. Review attachments and earlier emails separately.
2. Record the actual purpose at creation and the person who can explain it. Identify the legal advice sought or the litigation circumstances without stating the advice itself.
3. Specify the privilege basis and applicable law. Record any later disclosure and the resulting waiver assessment.
4. Mark the production decision, including any proposed redaction. Keep a controlled original and verify that redactions remove protected content from the copy supplied.

For Federal Court discovery, rule 20.17 of the Federal Court Rules 2011 requires the list to identify documents claimed as privileged and the grounds. Rule 20.02 preserves privilege against production under Part 20. If a claim is disputed, seek directions for determination. Under rule 20.35, the court can order production to itself and inspect a document to decide a privilege objection. Do not send disputed advice to the opponent merely to demonstrate the claim.

If privileged material is produced inadvertently, promptly identify the affected documents and notify the other lawyer. Seek a halt to use and circulation, return or deletion of copies and correction of the production record. Preserve the incident record and obtain court directions if agreement fails.

In Expense Reduction Analysts v Armstrong [2013] HCA 46, the High Court treated mistaken disclosure through discovery as a matter for court supervision and correction. It rejected automatic waiver on the facts. Prompt action matters, and relief depends on the circumstances.

Before serving a financial schedule, check its comments, linked files and supporting report against the privilege decisions. Confirm that the served version contains only the material the lawyer has authorised for production.
