Can a lawyer have Instagram? Can they post on TikTok? Is LinkedIn mandatory? These are some of the most frequently asked questions about legal marketing — and the answer to all is yes, with clear limits.
In this guide, you will learn exactly how to use each social network to attract clients without violating the OAB Code of Ethics.
Why Lawyers Need to Be on Social Media
On average, Brazilians spend 3 hours and 37 minutes per day on social media — the second highest rate in the world. Your potential clients are there. The question is not whether you should be on social media, but how.
Provision 205/2021 from the OAB is clear: lawyers can have professional profiles and publish content, as long as it is informative, educational, and moderate.
LinkedIn: The Number 1 Network for Law
LinkedIn is the most natural environment for lawyers. It is a professional network where technical content is valued and networking happens organically.
What to Post on LinkedIn
- Case law analyses: Comment on recent decisions with your technical interpretation
- Legislative changes: Explain the impact of new laws on businesses and individuals
- Blog articles: Share your articles with contextual commentary
- Anonymized cases: “A client approached me with X problem. The legal solution was Y.” (always without identifying)
- Events and lectures: Promote your participation in conferences and seminars
Ideal Frequency
3 to 5 posts per week is enough to build a presence on LinkedIn. Quality > quantity. A well-written technical article per week is worth more than shallow daily posts.
Instagram: Humanize Your Law Practice
Instagram is not incompatible with law — the mistake lies in the tone. Lawyers who treat Instagram as a storefront or lifestyle blog are risking a lawsuit from the OAB. Those who use it to educate and humanize are reaping results.
Formats that Work for Lawyers
- Educational carousel: 5-10 slides explaining a specific right (e.g., “5 worker rights you don’t know”)
- Short Reels: Legal tip in 30-60 seconds, explained in simple language
- Informative Stories: Share legal news with your commentary
- Behind-the-scenes posts: Study routine, preparation for hearings, office environment
What NOT to Do on Instagram
- Luxury photos associated with law (cars, trips, expensive restaurants)
- Stories with polls like “Need a lawyer? DM me”
- Photos of clients or hearings without authorization (even with a blur on the face)
- Using memes or excessively informal language that devalues the profession
YouTube: Authority in Video
YouTube is the second largest search engine in the world — and it is full of people searching for legal terms. A well-structured channel can become your largest source of organic clients.
Types of Videos that Work
- Classes: Complete explanations on a topic (e.g., “All about divorce — complete guide”)
- Q&A: Answer common questions in your area
- News commentary: Legal analysis of cases highlighted in the media
- Interviews: Conversations with colleagues from other specialties
TikTok: The Frontier of Digital Law
Yes, law works on TikTok. There are Brazilian lawyers with millions of views explaining consumer, labor, and family rights in 30-90 second videos.
The key on TikTok is accessible language. You are not speaking to judges — you are speaking to ordinary people who need to understand a right. If you can explain a complex legal concept in 60 seconds, TikTok is your channel.
Careful on TikTok
- Do not use dance trends or challenges — keep a professional tone
- Do not promise results or use legal clickbait
- Do not stage hearings or consultations
- Always make your OAB number clear in your bio
Editorial Calendar for Lawyers
A realistic frequency suggestion for those starting out:
| Network | Frequency | Content Type |
|---|---|---|
| 3-4x per week | Analyses, articles, comments | |
| 3x per week (feed) + daily stories | Educational carousels, Reels, behind-the-scenes | |
| YouTube | 1x per week | 5-15 min videos on specific topics |
| TikTok | 3-5x per week | 30-90 second snippets |
Tools to Manage Social Media
- Canva: Creation of graphics for carousels and posts
- CapCut: Video editing for Reels, TikTok, and Shorts
- Buffer / Later: Scheduling posts across multiple networks
- Notion / Trello: Planning topics and editorial calendar
Errors That Can Cost You Your OAB
- Answering specific questions in comments: This can constitute legal advice. Respond generically and invite for private contact
- Exposing clients or cases: Even without mentioning names, be careful with details that allow identification
- Debating with haters: Lawyers cannot argue on social media. Silence or institutional response
- Doing sales-tone lives: “Free Q&A” can be interpreted as solicitation
- Buying followers: Besides being ineffective, it violates professional ethics
Social media is an extension of your office. Every post, every story, and every comment reflects your professional image. Use them strategically, ethically, and consistently — and they will be your greatest allies in client acquisition.
