Why legal is a natural fit
Few purchases involve more research than hiring a lawyer. People want to understand their situation, the process and the likely cost before they call anyone, and many of them now start in ChatGPT. An ad that appears beside that research, from a firm licensed in the person's state, is a credible next step.
What OpenAI's policy requires
- Legal services advertisers are approved case by case.
- In the US, a firm can only show ads in jurisdictions where it is licensed.
- Ads cannot reference sensitive social issues, which is why practice areas such as immigration need careful handling or a different approach.
- Ads are not shown in sensitive personal conversations.
Those rules sit on top of your state bar's advertising rules, not instead of them. Disclaimers, claims about results and use of the word 'specialist' are still governed by the bar.
Practice areas that fit
| Practice area | What people ask first | Landing page should answer |
|---|---|---|
| Personal injury | Do I have a case? How long do I have? | Deadlines, what to gather, how fees work |
| Family law | How does custody work? What does divorce cost? | The process, timelines, a first-consultation outline |
| Estate planning | Do I need a trust? What happens without a will? | Plain comparisons and a checklist |
| Real estate | What does a closing attorney do? | Scope, timing and fixed-fee options |
| Employment | Was I wrongfully terminated? | What to document and next steps |
| Business law | Which entity should I form? | A comparison and when to get counsel |

Frequently asked questions
Can a law firm advertise nationwide in ChatGPT?
Only where it is licensed. OpenAI limits US legal ads to jurisdictions where the advertiser is licensed to practice.
Do bar advertising rules apply to ChatGPT ads?
Yes. A ChatGPT ad is attorney advertising, so the same rules on claims, disclaimers and solicitation apply.
Which practice areas should a firm avoid?
Anything that requires referencing sensitive social issues in the ad, such as immigration, needs careful review and may not be eligible in its usual form.
