Short answer: Arizona attorney advertising is governed by ER 7.1 through ER 7.5 of the Arizona Rules of Professional Conduct. But Arizona is not really a story about advertising rules. In 2021 Arizona became the first US state to permit nonlawyer ownership of law firms, eliminating the fee-sharing prohibition and creating an Alternative Business Structure licensing regime. That single change makes Arizona the most structurally different legal market in the country, and it has consequences for how legal services get marketed there. This guide sets out the Arizona attorney advertising rules that apply to a law firm website, and where firms most often fall short.
Most state-by-state advertising guides treat Arizona as a footnote with slightly unusual rule numbering. That misses the actual story.
What Arizona changed
Every other US state restricts nonlawyer ownership of entities providing legal services and restricts fee sharing with nonlawyers. Arizona removed that restriction and replaced it with a licensing framework. An Alternative Business Structure is an entity licensed by the Arizona Supreme Court to deliver legal services while including nonlawyer owners or outside investors, subject to conditions including a designated compliance lawyer.
Arizona also created a Legal Paraprofessional licence, allowing qualified non-attorneys to provide defined legal services directly. Both changes were deliberate market experiments aimed at access to justice, and both are real rather than theoretical — ABS licences have been issued to a range of entities.
Why this matters for a website
The framework’s central concern is consumer clarity about who is actually providing legal services and under what structure. That concern lands directly on the website, because the website is where a prospective client forms their understanding.
If you hold an ABS licence, you are operating under a structure the public is not familiar with. Do not assume your site can present itself identically to a traditional firm. Confirm your disclosure obligations rather than inferring them.
If you are a traditional Arizona firm, the change still affects you competitively. Some of your competitors now have access to outside capital, which typically shows up first in marketing spend. That is a strategic fact about the Arizona market, not a compliance one.
If a paraprofessional is involved, the scope of what that person may do is defined and limited. A website that blurs the line between attorney and paraprofessional services creates exactly the confusion the framework exists to prevent.
Arizona compared with every other state in this series
| Arizona | Every other state covered | |

| Nonlawyer firm ownership | Permitted, via ABS licence | Prohibited |
| Fee sharing with nonlawyers | Permitted within the framework | Prohibited |
| Outside investment in firms | Available | Not available |
| Non-attorney licensed providers | Legal Paraprofessionals | Rare or discontinued |
| Advertising rule citation | ER 7.1–7.5 | Typically Rules 7.1–7.5 |
The advertising rules themselves
On the conventional questions Arizona is unremarkable. ER 7.1 addresses false and misleading communications. Specialist claims require certification. Comparative superlatives require substantiation. There is no pre-filing requirement, so nothing is reviewed before publication.
One practical note on citation: Arizona’s use of the ER prefix means searches and templates built around “Rule 7.1” may not surface the Arizona provision. If you are auditing a multi-state firm’s site, that mismatch is an easy way to conclude Arizona has no equivalent rule when it does.
Arizona attorney advertising rules: frequently asked questions
Can non-lawyers own a law firm in Arizona?
Yes. Arizona eliminated the rule prohibiting fee sharing and nonlawyer ownership and created an Alternative Business Structure licensing regime, effective at the start of 2021. Arizona was the first US state to do this, and it remains the most permissive on ownership.
What is an Alternative Business Structure?
An ABS is an entity licensed in Arizona to provide legal services while including nonlawyer owners or investors. It is licensed by the Arizona Supreme Court and is subject to conditions, including designating a compliance lawyer.
Does an Arizona ABS have to disclose its ownership on its website?
Consumer clarity about who is providing legal services is a central concern of the ABS framework, and an entity holding an ABS licence is operating under a different structure from a traditional firm. Confirm your specific disclosure obligations with the Arizona Supreme Court rather than assuming your website needs no change.
Which rules govern attorney advertising in Arizona?
The Arizona Rules of Professional Conduct, where the advertising provisions are the Ethical Rules numbered ER 7.1 through ER 7.5. Note the ER prefix, which differs from most states’ citation format.
Can a marketing agency take equity in an Arizona law firm?
Arizona is the one state where this is structurally possible, subject to ABS licensing. It is a genuine change rather than a technicality, and it carries licensing obligations that fall on the entity, not just on the lawyers.
Arizona attorney advertising rules: the short version
If you take one thing from this guide, take this: the Arizona attorney advertising rules apply to every page a prospective client can reach, including campaign landing pages built outside your main website. That is usually where the gaps are.

Legal Web Agency is a marketing agency, not a law firm, and nothing here is legal advice. ABS licensing conditions and disclosure requirements are specific and evolving, and none is quoted here. Confirm current requirements with the Arizona Supreme Court or your ethics counsel before making any structural or disclosure decision.
