Important: This guide is written for marketers and non-lawyer readers who work with California attorneys. It is not legal advice, and nothing in it substitutes for consulting with California's Office of Chief Trial Counsel, the State Bar, or your own ethics counsel. Rules and interpretations change. Always confirm with the attorney and their compliance resources before publishing.

1. The four rules every marketer needs to know

California adopted its current Rules of Professional Conduct in November 2018, replacing the older rules with language closely tracking the ABA Model Rules. The advertising rules run from Rule 7.1 through Rule 7.5. For marketing purposes, four of them matter most.

Rule 7.5 covers firm names and letterheads. It is less important day-to-day for content marketing but matters if you are renaming a firm.

2. Rule 7.1: false and misleading communications

This is the umbrella rule and it is surprisingly broad. Rule 7.1 prohibits any communication that is false or misleading. A communication is misleading if it contains a material misrepresentation of fact or law, or omits a fact necessary to make the statement considered as a whole not materially misleading.

In practice, this rule catches three common marketing mistakes.

First, unverifiable superlatives. "California's top employment lawyer." "The best entertainment firm in Los Angeles." These are misleading unless you can substantiate them, and "best" is almost never substantiable.

Second, unjustified expectations about results. "We win 95 percent of our cases." Even if technically true, this sets up an expectation that the next client's case will also be won. Rule 7.1 prohibits statements that would create an unjustified expectation about results.

Third, omitting context that makes a true statement misleading. "Recovered $10 million for a client" is true but misleading if it implies that outcome is typical. A disclosure is usually required.

3. Rule 7.2: advertising, testimonials, and referral fees

Rule 7.2 explicitly permits advertising. This is important. California lawyers can absolutely run paid ads, content marketing, LinkedIn campaigns, and search advertising. The rule just constrains how.

Testimonials

Testimonials and endorsements are permitted with restrictions. They cannot be false or misleading. If a testimonial includes a comparison to other lawyers, or implies guaranteed results, or is compensated without disclosure, it violates the rule. Best practice: any website testimonial should include a disclosure that past results do not guarantee future outcomes, and any paid testimonial must clearly disclose the compensation.

Referral fees and things of value

A California lawyer cannot give anything of value in exchange for a recommendation, with limited exceptions. This is where lawyer referral services, lead generation vendors, and some influencer marketing arrangements run into trouble. If a marketer is paying a third party to send clients to an attorney in exchange for a cut of the fee, that arrangement is almost certainly prohibited.

Reciprocal referrals between lawyers are also regulated. A reciprocal referral arrangement cannot be exclusive, and the client must be informed.

4. Rule 7.3: solicitation

Rule 7.3 prohibits certain kinds of in-person, live telephone, or real-time electronic solicitation of prospective clients when a significant motive is the lawyer's pecuniary gain. The rule has important exceptions for existing clients, family members, and other lawyers.

For content marketing, the key takeaway is that ordinary advertising and content (website, blog, LinkedIn posts, email newsletters to subscribers) is not solicitation in the 7.3 sense. Cold outreach is trickier. LinkedIn InMail to a stranger offering legal services can cross into prohibited solicitation depending on the content and context.

5. Rule 7.4: fields of practice and specialization

Rule 7.4 permits a lawyer to communicate that they practice in particular fields. It restricts the use of the word "specialist" to lawyers who are certified as specialists by the State Bar or an accredited entity.

In practice, this means a lawyer can say "I focus my practice on employment litigation" or "my practice is concentrated in entertainment law" freely. A lawyer cannot say "I am a specialist in employment litigation" unless they are actually a Board of Legal Specialization certified specialist.

Marketers: audit every page of copy and every LinkedIn bio for the word "specialist" or "specialize" and confirm certification before publishing.

6. Rule 7.5: firm names and letterheads

Rule 7.5 requires that firm names not be false or misleading. You cannot use the name of a lawyer who is not actually in the firm. Trade names are permitted if they comply with Rule 7.1. This matters mostly at firm formation or rebrand. Day-to-day content marketing rarely touches it.

7. Common violations we see on LinkedIn and websites

In auditing California law firm marketing, these are the violations that come up most often.

8. A compliance checklist for every piece of content

Before anything goes live, run it through this seven-point check.

  1. Are any factual claims substantiated?
  2. Are there any superlatives that cannot be supported?
  3. Does any dollar figure or win percentage have an appropriate disclosure?
  4. Does the content use the word "specialist" or "specialize"? If yes, is the attorney certified?
  5. Are testimonials real, attributable, and disclosed if compensated?
  6. Is there any guarantee of outcome, implied or explicit?
  7. Is the "attorney advertising" or similar disclosure present where required?

If any answer is unclear, the content does not ship until the attorney signs off.

Marketing that respects the rules.
