California Conflict Waiver Sample: Required Elements and Limits

A California conflict waiver sample is only as good as the specific facts it discloses: under Rules 1.7 and 1.9 of the California Rules of Professional Conduct, a valid waiver is a written disclosure tailored to the actual conflict, signed by every affected client after the lawyer has explained the relevant circumstances, the material risks, and the reasonably foreseeable adverse consequences. A template can give you the structure. It cannot supply the content that makes the consent “informed.”

The sections below walk through what a California waiver letter needs to say, what the lawyer must independently confirm before relying on it, and where waivers fail even when signed.

What a California Conflict Waiver Has to Accomplish

The controlling standard is “informed written consent,” defined in Rule 1.0.1. The client must agree in writing after the lawyer has communicated and explained the relevant circumstances and the material risks, including any actual and reasonably foreseeable adverse consequences.¹

Two rules trigger that requirement. Rule 1.7 governs current-client conflicts: direct adversity between two current clients, and situations where the lawyer’s work for one client is at significant risk of being limited by obligations to another client, a former client, a third party, or the lawyer’s own interests. Rule 1.7 also requires written disclosure, short of full consent, when the lawyer or someone in the firm has a legal, business, financial, or personal relationship with a party or witness in the matter, or when opposing counsel is a close family member or shares the lawyer’s household.²

Rule 1.9 covers former clients. A lawyer who previously represented someone cannot take on a new client in the same or a substantially related matter, adverse to the former client, without the former client’s informed written consent. The rule also bars using or revealing protected information from the former representation regardless of whether the matters are related.³

Elements to Include in the Waiver Letter

The State Bar does not publish a mandatory template. An effective California waiver letter generally contains the following:

Identification of all affected clients. Name every party whose interests are affected, not only the client receiving the letter.
A specific description of the conflict. Explain the facts creating the conflict in plain language. Boilerplate like “a potential conflict may exist” is not enough.
The nature and scope of the representation. Describe what the lawyer will do for each client and how the representations relate.
Material risks and foreseeable consequences. Spell out what could go wrong. If the lawyer represents both sides of a transaction, say that information learned from one client could be relevant to the other and that the lawyer cannot take sides if a dispute develops.
Limitations on the representation. Identify constraints the conflict imposes: information that cannot be shared between clients, restrictions on advocacy, and any subject matter the lawyer will not address.
The client’s right to decline and to seek independent advice. Rule 1.7 does not on its own require the lawyer to tell the client to consult separate counsel, but including that statement strengthens the waiver if it is challenged later.
A signature line for each affected client. The signature confirms the client has read the disclosure, understands the risks, and consents.

The disclosure must fit the specific situation. A form letter that recites rule language without connecting it to the facts is the kind of waiver that comes apart under a disqualification motion. The more concrete the description, the more likely a court will find the consent genuinely informed.

Two conflict types trigger additional drafting requirements beyond Rule 1.7. When the lawyer enters a business transaction with the client, Rule 1.8.1 requires the lawyer to advise the client in writing to seek independent counsel and to ensure the transaction is fair.⁴ When someone other than the client pays the fee, such as an insurer or employer, Rule 1.8.6 requires the client’s informed written consent, protection of confidentiality, and assurance that the payer will not interfere with the lawyer’s independent judgment.⁵

Conditions the Lawyer Must Satisfy Beyond the Client’s Signature

A signed waiver is necessary but not sufficient. Rule 1.7(d) requires the lawyer to independently confirm three things before the representation may proceed:

Reasonable belief in competent representation. The lawyer must genuinely believe they can provide competent and diligent work for every affected client. This is judged objectively, and the assessment happens before asking for consent.
No legal prohibition. The representation cannot violate any statute or regulation. Business and Professions Code section 6131, for example, bars former prosecutors from working with the defense on a case they personally handled.
No adverse claims in the same proceeding. The lawyer cannot represent one client asserting a claim against another client the lawyer also represents in the same litigation or tribunal.²

If any of these fail, no signed waiver can cure the conflict.

Conflicts That Cannot Be Waived

Rule 1.7(d) marks three bright-line limits, and any of them makes a conflict non-consentable regardless of what the client signs: the lawyer cannot reasonably believe competent representation is possible; the representation is prohibited by law; or the lawyer would be asserting one client’s claim against another client the lawyer represents in the same proceeding.²

A fourth situation is functionally non-consentable even though the rule does not label it that way. When the lawyer’s duty of confidentiality to one client prevents the disclosures needed to obtain informed consent from another, the consent process itself becomes impossible. You cannot explain a conflict you are not permitted to describe.

Advance Waivers for Future Conflicts

Comment [9] to Rule 1.7 permits informed written consent to conflicts that have not yet materialized, but enforceability depends on how well the waiver anticipated the situation and how sophisticated the client is. A detailed advance waiver signed by a corporate client with in-house counsel is on much firmer ground than a boilerplate form signed by an individual consumer. Whether the client had independent counsel when signing also matters.⁶

Advance waivers cannot reach conflicts that turn out to be non-consentable under Rule 1.7(d). If the situation that later develops involves adverse claims in the same litigation, or the lawyer cannot competently represent all affected clients, the earlier consent is worthless no matter how comprehensive its language.

Imputation Across the Firm

Under Rule 1.10, one lawyer’s conflict usually spreads to every other lawyer in the firm, so the waiver typically has to work firm-wide. There are two exceptions. A conflict based purely on one lawyer’s personal interest that poses no significant risk of limiting the representation is not imputed. And when the conflict comes from a lawyer’s prior firm, the new firm can use a screen: the conflicted lawyer is walled off from the matter, receives no fee from it, and the former client is promptly notified in writing of the screening arrangements.⁷

Imputed conflicts can be waived by each affected client under the same standards that apply to Rule 1.7 waivers generally.

What a Defective or Missing Waiver Costs

State Bar Formal Opinion No. 1989-115 spells out the exposure. A court can disqualify a conflicted lawyer even if the client signed a waiver, when continued representation would seriously compromise the integrity of the proceedings. That authority is independent of client consent.⁸

Discipline is a separate track. An undisclosed conflict, or one the lawyer should not have taken on, exposes the lawyer to State Bar discipline regardless of whether a waiver was signed. If the lawyer realizes mid-representation that competent work is no longer possible, failing to withdraw is itself a violation.⁸

Civil liability follows the same pattern. A waiver does not block a malpractice claim when the conflict actually impaired the quality of the services, and any attempt to use a conflict waiver to prospectively limit malpractice liability is itself an ethical violation. A lawyer discharged for an ethical violation can also be required to forfeit fees earned in the representation, and a fee forfeiture claim can proceed without proof of specific client damages.⁸

When to Redo the Waiver

A signed waiver is not open-ended. Comment [10] to Rule 1.7 makes clear that a material change in circumstances requires new disclosures and, where applicable, fresh informed written consent. Without that renewed consent, the lawyer may need to withdraw from one or more of the representations to avoid the conflict. The duty of confidentiality to any client the lawyer stops representing continues after the relationship ends.⁹
