California Bar Confidentiality
Last updated: May 2, 2026
Confidentiality questions are one of the highest-leverage areas to study for the California Bar. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.
The rule
Under California Rule of Professional Conduct 1.6 and Business & Professions Code §6068(e), a lawyer must maintain inviolate the confidence, and at every peril to himself or herself preserve the secrets, of the client. California treats confidentiality as nearly absolute and is the strictest jurisdiction in the United States. The ONLY express exception that permits (but never requires) disclosure of confidential information is to prevent a criminal act that the lawyer reasonably believes is likely to result in death of, or substantial bodily harm to, an individual — and only after the lawyer has, if reasonable, made a good-faith effort to dissuade the client and informed the client of the lawyer's intended disclosure. California has NO exception for preventing or rectifying client financial fraud, NO crime-fraud disclosure exception parallel to ABA Model Rule 1.6(b)(2)–(3), and the duty survives the engagement and the client's death.
Elements breakdown
Duty of Confidentiality (Cal. RPC 1.6 / Bus. & Prof. Code §6068(e))
A lawyer must not reveal information protected by the duty of confidentiality without informed consent of the client or unless a narrow statutory exception applies.
- Information acquired by virtue of representation
- Client has not given informed written/expressed consent
- No statutory exception authorizes disclosure
- Lawyer reveals or uses information adverse to client
Common examples:
- Information learned during the representation
- Information learned before formation if related to prospective representation
- Information protected even if publicly available elsewhere
- Information whose disclosure would be embarrassing or detrimental
Death-or-Substantial-Bodily-Harm Exception (Cal. RPC 1.6(b))
A lawyer MAY, but is not required to, reveal confidential information to the extent the lawyer reasonably believes disclosure is necessary to prevent a criminal act likely to result in death or substantial bodily harm.
- Reasonable belief disclosure is necessary
- Criminal act (not merely tortious or fraudulent)
- Likely to result in death or substantial bodily harm
- If reasonable, lawyer first made good-faith effort to dissuade client
- If reasonable, lawyer informed client of intended disclosure
- Disclosure no greater than necessary to prevent harm
Informed Consent Waiver
The client may waive confidentiality by giving informed consent after the lawyer communicates the relevant circumstances, material risks, and reasonably available alternatives.
- Lawyer communicates relevant circumstances
- Lawyer communicates material risks of disclosure
- Lawyer communicates reasonably available alternatives
- Client agrees to disclosure with that information
Self-Defense / Fee-Dispute Use (Cal. RPC 1.6, Comment; Evid. Code §958)
A lawyer may use or reveal confidential information to the extent reasonably necessary to establish a claim or defense in a controversy between the lawyer and client, to defend against criminal or civil charges arising from the representation, or to respond to allegations of wrongdoing.
- Controversy or claim involving the lawyer's conduct
- Information reasonably necessary to defend or collect
- Disclosure no broader than required for the proceeding
Confidentiality vs. Attorney-Client Privilege
The Cal. RPC 1.6 / §6068(e) ethical duty is broader than the Evidence Code §954 privilege; the privilege governs compelled testimony in proceedings, while the duty governs voluntary disclosure outside proceedings.
- Privilege: confidential communication between lawyer and client
- Privilege: made for purpose of legal advice
- Privilege: not waived by client
- Duty: covers all client information regardless of source or privilege status
Survival After Engagement and Death
The duty of confidentiality and the attorney-client privilege both survive termination of the representation, and the privilege survives the client's death (subject to limited probate-related exceptions in Evid. Code §957).
- Representation has ended or client has died
- Information was acquired during or in contemplation of representation
- No statutory or testamentary-document exception applies
Common patterns and traps
The ABA-Model-Rules Switch
The classic California PR distractor states a perfectly correct ABA Model Rule 1.6 exception — disclosure to prevent or rectify substantial financial injury, disclosure to comply with court order, disclosure to obtain ethics advice — and offers it as the answer. California has not adopted those exceptions. A candidate trained on a national bar prep diet of Model Rules will pick the ABA-flavored answer reflexively.
An answer choice reading 'Yes, the lawyer may disclose to prevent substantial financial harm to a third party' or 'Yes, because the crime-fraud exception applies.'
Permissive-Treated-as-Mandatory
Even when California's narrow death-or-substantial-bodily-harm exception clearly applies, disclosure is permissive ('may') and only after the dissuade-and-warn predicate. A trap answer says the lawyer 'must' or 'is required to' disclose. Picking an obligatory-disclosure choice in California PR is almost always wrong.
An answer reading 'The lawyer must disclose the threat to the police' or 'The lawyer is required to warn the intended victim.'
Privilege-Duty Conflation
A vignette tests the §6068(e) ethical duty (e.g., voluntary disclosure to a journalist, opposing counsel, or in a non-legal setting) but the wrong answer reasons through Evidence Code privilege exceptions like crime-fraud (§956) or the joint-client exception (§962). The privilege exceptions excuse compelled testimony in legal proceedings; they do NOT authorize a California lawyer to volunteer information.
An answer reading 'The lawyer may disclose because the crime-fraud exception destroys the privilege' when the question concerns voluntary disclosure outside any proceeding.
Predicate-Skip Trap
Even where Cal. RPC 1.6(b) authorizes disclosure, the rule requires (where reasonable) (1) a good-faith effort to dissuade the client and (2) informing the client of the intended disclosure. An answer that allows immediate disclosure without these predicates is wrong if the predicates were reasonable to perform.
'Yes, the lawyer may immediately notify the police' — without any indication the lawyer first attempted to dissuade or warn the client.
Self-Defense Overreach
The self-defense / fee-dispute use of confidential information is limited to what is reasonably necessary for the proceeding. A trap answer lets the lawyer publish the client's secrets broadly (e.g., post on social media to defend reputation, or volunteer information beyond what the tribunal needs) under the banner of self-defense.
'The lawyer may publicly disclose the client's prior statements to defend her professional reputation against the State Bar complaint.'
How it works
California protects client information more aggressively than any other jurisdiction. Suppose your client, Reyes, tells you mid-litigation that he plans to lie at deposition next week and also mentions, almost in passing, that he intends to burn down his ex-business-partner's empty warehouse this Saturday. Under the ABA Model Rules you'd have several disclosure options, including the crime-fraud and financial-injury exceptions. Under California you have essentially one: because the arson is a criminal act likely to cause substantial bodily harm (an unoccupied warehouse may still endanger firefighters and neighbors), Cal. RPC 1.6(b) permits — but does not require — you to disclose the minimum necessary to prevent it, after first attempting to dissuade Reyes and warning him you may disclose. Reyes's intention to lie at deposition is fraud on the tribunal, governed by Cal. RPC 3.3, NOT by §6068(e), and triggers remonstrance and possibly withdrawal — never broadcast disclosure of the underlying confidence to opposing counsel.
Worked examples
Under the California Rules of Professional Conduct, may Patel disclose the LLC's planned tax fraud to the IRS without the client's consent?
- A Yes, because California Rule 1.6(b) permits disclosure to prevent a client's ongoing or future crime.
- B Yes, because the crime-fraud exception strips confidentiality from communications made in furtherance of a fraud.
- C No, because California's only Rule 1.6 disclosure exception applies to criminal acts likely to cause death or substantial bodily harm, and pure financial fraud does not qualify. ✓ Correct
- D No, but Patel must immediately withdraw and report the LLC's plan to the State Bar.
Why C is correct: California is the strictest confidentiality jurisdiction. Under Cal. RPC 1.6(b) and Bus. & Prof. Code §6068(e), the only express exception authorizing voluntary disclosure of confidential information is to prevent a criminal act likely to result in death or substantial bodily harm. Tax fraud, however serious, is a financial crime — not a threat of physical harm — so no exception authorizes disclosure. Patel must keep the confidence, though Patel may need to counsel the client, refuse to assist, and consider withdrawal under Cal. RPC 1.16.
Why each wrong choice fails:
- A: This describes the ABA Model Rule 1.6(b)(2)–(3) financial-fraud exception, which California has not adopted. California's Rule 1.6(b) is limited to death or substantial bodily harm. (The ABA-Model-Rules Switch)
- B: The crime-fraud doctrine (Evid. Code §956) is an evidentiary-privilege exception governing compelled testimony, not a disclosure exception under Cal. RPC 1.6 or §6068(e). It does not authorize voluntary disclosure to the IRS. (Privilege-Duty Conflation)
- D: There is no California rule requiring an attorney to report a client's prospective financial fraud to the State Bar. Withdrawal may be permitted or required under Cal. RPC 1.16 if the lawyer would be assisting the fraud, but the duty of confidentiality survives withdrawal — and broadcasting the plan to the State Bar would itself violate §6068(e). (Permissive-Treated-as-Mandatory)
Under the California Rules of Professional Conduct, may Reyes disclose Ortega's threat to Ortega's wife and the police?
- A No, because the duty of confidentiality under §6068(e) is absolute and admits of no exception.
- B Yes, because Reyes reasonably believes disclosure is necessary to prevent a criminal act likely to result in substantial bodily harm and has already attempted to dissuade Ortega and warned of the intended disclosure. ✓ Correct
- C Yes, because California requires lawyers to disclose threats of violence to potential victims.
- D No, because Ortega's threat was made in a confidential communication and the attorney-client privilege bars Reyes from revealing it.
Why B is correct: Cal. RPC 1.6(b) authorizes — but does not require — a lawyer to reveal confidential information to the extent the lawyer reasonably believes necessary to prevent a criminal act likely to result in death or substantial bodily harm, after (where reasonable) the lawyer has attempted to dissuade the client and informed the client of the intended disclosure. Reyes has performed both predicates, and a planned violent assault on the wife squarely fits the death/SBH category. Disclosure is permitted (though Reyes may also choose not to disclose).
Why each wrong choice fails:
- A: While §6068(e) is famously strict, it is not absolute — Cal. RPC 1.6(b) creates the death-or-substantial-bodily-harm exception, which precisely covers this scenario.
- C: California's exception is permissive, not mandatory. The rule says a lawyer 'may' disclose; it does not require disclosure even when the predicates are met. Picking a 'must disclose' answer in California PR is almost always wrong. (Permissive-Treated-as-Mandatory)
- D: This conflates the §954 attorney-client privilege with the §6068(e) ethical duty. Even setting privilege aside, Cal. RPC 1.6(b) provides the operative authorization to disclose; the privilege analysis is irrelevant where Reyes is voluntarily disclosing under an express ethical exception. (Privilege-Duty Conflation)
Under the California Rules of Professional Conduct, what may Nakashima reveal?
- A Nakashima may submit the documents and witness notes to the State Bar but may not post the public blog entry, because the self-defense use of confidential information is limited to what is reasonably necessary for the proceeding. ✓ Correct
- B Nakashima may submit the documents and post the blog entry, because once a client files a complaint the duty of confidentiality terminates entirely.
- C Nakashima may neither submit the documents nor post the blog entry, because the duty of confidentiality survives the engagement and prohibits any disclosure absent the client's informed written consent.
- D Nakashima may post the blog entry but must seek a court order before submitting the documents to the State Bar.
Why A is correct: California recognizes a self-defense use of confidential information (reflected in Cal. RPC 1.6 commentary and Evid. Code §958) that allows a lawyer to reveal confidential information to the extent reasonably necessary to defend against allegations of wrongdoing — including a State Bar complaint arising from the representation. That justifies submitting the signed document, witness notes, and Singh's emails to the State Bar. It does NOT justify a public blog entry, which goes far beyond what is reasonably necessary for the disciplinary proceeding.
Why each wrong choice fails:
- B: A client's complaint does not vaporize the duty of confidentiality. Self-defense allows only the disclosure reasonably necessary to defend, not a broadcast. (Self-Defense Overreach)
- C: Although confidentiality survives the engagement, California recognizes a self-defense exception permitting reasonably necessary disclosure to defend against charges arising from the representation. Refusing to submit the very evidence that exonerates Nakashima would be a misreading of the rule.
- D: No court order is required to submit information to the State Bar in defense of a disciplinary complaint; the self-defense use is built into the ethical rules themselves. And the inverted result — allowing the public blog but barring the disciplinary submission — gets the rule exactly backwards. (Self-Defense Overreach)
Memory aid
California's only Rule 1.6 disclosure exception is 'DASH-DISSUADE-DISCLOSE': Death/Substantial bodily Harm, Dissuade first, Disclose minimum. If the threat is anything else — money, property, fraud, perjury — the answer is almost always 'maintain confidence.'
Key distinction
Confidentiality (Cal. RPC 1.6 / §6068(e)) governs what a California lawyer may voluntarily reveal and is among the strictest in the nation; attorney-client privilege (Evid. Code §954) governs what a lawyer can be compelled to testify about and recognizes more exceptions (e.g., crime-fraud under §956, fiduciary breach, joint-client). An MBE-style answer that says 'the lawyer must disclose because the crime-fraud exception applies' is wrong in California — that exception exists in the privilege rules but not in §6068(e).
Summary
In California, a lawyer must preserve client secrets at every peril, with the only voluntary-disclosure exception being to prevent a criminal act likely to cause death or substantial bodily harm — and even then disclosure is permissive, not mandatory.

What is confidentiality on the California Bar?
Under California Rule of Professional Conduct 1.6 and Business & Professions Code §6068(e), a lawyer must maintain inviolate the confidence, and at every peril to himself or herself preserve the secrets, of the client. California treats confidentiality as nearly absolute and is the strictest jurisdiction in the United States. The ONLY express exception that permits (but never requires) disclosure of confidential information is to prevent a criminal act that the lawyer reasonably believes is likely to result in death of, or substantial bodily harm to, an individual — and only after the lawyer has, if reasonable, made a good-faith effort to dissuade the client and informed the client of the lawyer's intended disclosure. California has NO exception for preventing or rectifying client financial fraud, NO crime-fraud disclosure exception parallel to ABA Model Rule 1.6(b)(2)–(3), and the duty survives the engagement and the client's death.
