WhatsApp for Lawyers and Law Firms: Rules for Client Communication
Clients now write on WhatsApp before they call their lawyer: "When is the hearing?", "I sent the document, did you see it?", "Has there been any progress on the file?" Because it is fast, easy, and familiar, WhatsApp has become widespread in law firms too. However, this field has two limits that differ from other sectors: the professional rules on advertising and client solicitation, and the duty of confidentiality. This article is not a legal opinion; it describes, in general terms, which uses of WhatsApp are reasonable in law firms and which are risky. For binding limits, you should consult the regulations and professional rules of your own bar association.
Draw the Line First: Information Yes, Advertising No
In the legal profession, advertising and client solicitation aimed at attracting business are restricted within the framework of professional rules. So, like other businesses in the sector, sending bulk campaign messages, spreading promotional content such as "first consultation free" or "discount in divorce cases," or promoting the firm to a list of people you do not know all carry serious risk. Professional bodies can initiate disciplinary proceedings on these matters.
For this reason, it is useful to divide WhatsApp use into two groups:
| Use | General approach |
|---|---|
| Appointment, hearing, or document information for an existing client | Considered appropriate as part of the service; with the minimum necessary information |
| Appointment confirmation for a prospective client | Reasonable if the client has contacted you; must not contain advertising |
| Introducing the firm to people you do not know | Risky, avoid |
| Campaigns, discounts, fee announcements | Avoid |
| Automatic replies giving legal advice | Avoid; the bot should only direct people |
If you are unsure whether a piece of content counts as advertising, consult the opinion of the bar association you belong to. Nothing in this article should be taken as a definitive legal interpretation.
Confidentiality: What to Write on WhatsApp and What Not to
Lawyer-client communication is covered by the duty of confidentiality. WhatsApp messages are end-to-end encrypted, but a phone can be stolen, a screen can be watched, the backup is linked to another account, and chats may be left open on a computer. For a safe arrangement, the following rules help:
- Do not write the content of a file in a message. Saying "The hearing in your file is on March 14" is enough; do not write an indictment summary, witness statement, or criminal record details.
- Receive identity and sensitive documents through another secure channel. Instead of uploading documents such as an ID photocopy, a health report, or bank details to WhatsApp, use your firm's secure method.
- Verify the client's identity. Confirm by phone or in person that someone who reports a new number is really the client.
- Be careful with groups. Even people with joint cases should not be in the same group; each client's file is separate. Groups containing co-defendants or people linked to the opposing side can create a serious confidentiality problem.
- Protect your devices. A screen lock, two-step verification, and checking linked devices should be firm habits. For details, see the security measures in our account restriction guide.
Special categories of personal data, such as health, criminal, and financial information, are also protected under the KVKK (Personal Data Protection Law). If you share and store such data by message, clarify your legal basis and retention periods.
Appointment and Hearing Reminders
A short reminder sent in response to a client's request for information is a natural part of the service. Do not include the subject or the name of the party in the message; write only the date, time, and place.
Hello Ayşe Hanım, the hearing regarding your file is on Thursday, March 14, at 10:30. Please bring your ID with you when you come to the courthouse. We will inform you if there are any changes.
Hello Mehmet Bey, we wanted to remind you of our meeting tomorrow at 15:00. We are meeting at our office at Atatürk Cad. No:5. If you would like to change it, you can reply to this message.
The business and names are fictional. For the general logic of appointment reminders, see our appointment reminder article. If a client says "Don't write, call," respect that preference.
Managing Incoming Messages
In law firms, the biggest problem is not the number of messages but the uncertainty about which file a message belongs to. Set up a simple arrangement:
- Create a record card for each client: name, file number, and preferred means of communication.
- When a message arrives, note the file number next to the message, or ask the client to state it.
- Tell the client clearly when they will receive a reply; make a sustainable promise such as "within 24 hours during working hours."
- Do not leave important instructions (payment, power of attorney, deadlines) on WhatsApp alone; confirm them by email or in a written record.
- Record each action not only as a message but also as a note in the file.
The reply to a client's first message should also be thought through in advance; at first contact, the aim is not to give legal information but to direct the person to the right person at the right time.
When a New Person Writes for the First Time
When someone you have never met writes, "I want to get divorced, how much does it cost?", the reply matters both ethically and practically. Instead of writing a price or the likelihood of a case, directing the person to a meeting protects your professional boundaries. The suggested flow:
- Let them know you have received their message and when you will get back to them.
- Do not ask for the details of the matter in writing; "You can write your full name and a suitable day and time for an appointment" is enough.
- Discuss the fee, the outcome of the case, and strategy in the meeting, not in the message.
- Do not request a power of attorney or documents before the meeting has taken place.
- Do not add to a list someone who is not a client unless they have consented.
This approach responds to a request for information without including promotion. Keep your message language plain, respectful, and neutral; avoid bold claims such as "the best lawyer."
Automatic Replies: Direction Only
Setting up an out-of-hours automatic reply at your office is reasonable to let a client know their message has arrived. However, the reply must not contain legal commentary, the likelihood of a case, or a prediction of success. Example:
Hello, your message has reached our office. Our working hours are weekdays 09:00-18:00; we will get back to you on the first working day. For confidentiality reasons, please do not send documents or identity details through this channel.
In WapFlow, you can define such an out-of-hours message with Reply Rules and Working Hours; ready-made text examples are in our auto-reply message examples. Do not use the AI bot to answer legal questions; incorrect or incomplete information can harm the client, and the responsibility is yours.
WapFlow's Place in a Law Firm
Think of WapFlow not as a bulk marketing tool but as a panel that makes management easier. It can be used for tasks such as appointment reminders for existing clients, out-of-hours replies, and address book organization. Using data extraction tools (finding businesses or people via Google Maps, web scraping) to win clients conflicts with the advertising and client solicitation bans mentioned above; we do not recommend it.
Also, WapFlow is not the official WhatsApp Business API; it is based on linked devices and carries a risk of account restriction. To avoid putting the firm's main contact number at risk, consider a separate number if you use the panel. For an overview of the general principles of consent and commercial messages, see our İYS and KVKK guide.

Frequently Asked Questions
Can a lawyer send bulk messages to clients?
Providing service-related information to existing clients is not the same as advertising. Bulk messages with an advertising character are risky. If you are unsure, consult your bar association.
Can WhatsApp conversations be used as evidence?
Their evidential value depends on the specific case and the legislation. Back up important conversations and assess their legal value separately for your own file.
What should I do if a client sends a document?
Transfer the document received to the file, and do not keep an unnecessary copy on WhatsApp. For sensitive documents, suggest a secure channel.
Should I only work with clients through WhatsApp?
No. WhatsApp is practical for quick exchanges of information, but for important decisions, payment instructions, and powers of attorney, use written and signed records. Treat WhatsApp as a service channel, not as the only record of the file.
Can a bot give clients legal information?
We do not recommend it. The bot should only answer on matters that have no legal consequences, such as contact information, working hours, and appointment directions.
To organize communication within your office, set up out-of-hours replies, and send service-related reminders to existing clients, you can look at WapFlow; always set your advertising limits according to your own professional rules.
