Is it legal to record a sales meeting? Switzerland, France and the EU, consent first

Recording a client meeting can be lawful, and it can also be a criminal offence. The difference is almost always the same thing: whether every participant knowingly agreed before the recording started. Here is what the rules ask, country by country, and how to ask in practice.

Is it legal to record a sales meeting? In Switzerland, France and the rest of the EU, the safe answer is yes, if every participant has been clearly informed and has agreed before you start, and if the recording is then handled as the personal data it is. This page is general information, not legal advice.

Recording a sales meeting legally: the short answer

Two sets of rules usually apply at the same time. Criminal law protects private conversations against being recorded without consent. Data protection law (the GDPR in the EU, the revised Federal Act on Data Protection, nLPD, in Switzerland) governs what you do with the recording afterwards. Consent satisfies the first and is only the starting point for the second. A consent routine that holds up in both usually looks like this:

  • Ask out loud, before recording. Not in the small print of a contract signed weeks earlier.
  • Ask every participant. Both partners at the kitchen table, and anyone who joins the meeting later.
  • Say why. Coaching, quality of advice, an accurate record of what was promised. The purpose you state is the purpose you are bound to.
  • Keep proof. The agreement, timestamped, stored with the recording.
  • Make no an easy answer. If the client refuses or changes their mind, the recording stops and the meeting continues.

Switzerland: art. 179ter of the Criminal Code and the nLPD

In Switzerland, article 179ter of the Criminal Code makes it an offence for a participant to record a non-public conversation without the consent of the other participants, and also covers storing or using such a recording. A sales meeting in a home, an office or a closed showroom is a non-public conversation. The exception some people cite for business calls concerns telephone conversations, not a face-to-face meeting. Our article on recording a sales meeting in Switzerland under art. 179ter sets out the text and what solid consent looks like.

Consent does not settle everything. The nLPD still applies to the recording: a defined purpose, proportionality, a limited retention period, information and the rights of the people recorded. In practice, write down the purpose and the retention period before the first recording, and be ready to tell a client where the recording is stored. And when the recordings concern your own reps, Swiss employment law adds its own requirements, covered in our article on what an employer must do before recording reps.

France and the EU: GDPR, CNIL guidance and criminal law

Under the GDPR, a recording of an identifiable person is personal data, and processing it needs a lawful basis under article 6(1), such as consent or a legitimate interest. Where you rely on consent, the GDPR defines it as a freely given, specific, informed and unambiguous indication of the person's wishes (article 4(11)); you must be able to demonstrate it (article 7(1)); the person may withdraw it at any time (article 7(3)); and the required information must be given at the time the data are obtained (article 13(1)).

In France, the CNIL's guidance on listening to and recording calls at work is the closest official reference for a sales team. It accepts purposes such as training employees, evaluating them and improving service quality; it rules out permanent or systematic recording unless a law requires it; it requires the other party to be told at the start of the conversation about the recording, its purpose and their right to object; and it sets maximum retention periods of six months for recordings and one year for analysis documents. The guidance is written for telephone calls. Applying its logic to a meeting in a client's home is our reading, not an official position. The CNIL also lists articles 226-1 and following of the French Criminal Code, which protect private life, among the rules that apply.

What to take away

Two questions, answered separately: did every participant agree before the recording started, and is the recording then handled with a stated purpose, a retention limit and the person's rights respected? A yes to the first does not answer the second.

Other countries

Rules differ elsewhere. Some jurisdictions allow a participant to record a conversation without telling the others; others require the agreement of everyone involved, and some sectors add their own rules. If your team sells outside Switzerland and the EU, check the local rule with a lawyer before recording. Asking every participant for consent is the approach that holds up in the widest range of places.

How to ask for consent in a client's home

Once everyone is seated, before any selling: "Before we start, I'd like to record our conversation. It helps me make sure I don't forget anything you tell me, and my company uses it to train its advisors. The recording stays with us and is deleted after a set period. Is that all right with both of you?" Wait for a clear yes from each person. If someone joins later, ask again. If the answer is no, put the phone away and carry on: a meeting without a recording is better than a lost client. Our guide to the best app to record in-person meetings lists what a tool should do to support this step.

How MIHOS handles consent

MIHOS records in-person sales meetings only with the client's consent, stores recordings in Switzerland, and does not use voiceprints or emotion analysis. The meeting is scored against your own method, and each rep gets coaching linked to the timestamped passage of the transcript. Consent is part of the workflow, so the rep in the field has nothing to remember and the compliance file exists from the first meeting.

Frequently asked questions

Can I record a client meeting secretly if it is only for my own notes? In Switzerland, recording a non-public conversation without the other participants' consent is an offence under art. 179ter, whatever the purpose. In France and the EU, secret recording also raises criminal and data protection issues. Ask first.

Is a clause in the terms and conditions enough? It is weak evidence of what happened in the room. A spoken request at the start of the meeting, with the agreement stored alongside the recording, is far more robust.

How long can recordings be kept? No longer than the purpose requires. For call recordings at work, the CNIL sets a maximum of six months for recordings and one year for analysis documents; use similar short periods for meetings unless a specific rule requires otherwise.

What if one of two clients refuses? Do not record. Every participant must agree.

Does the client's consent also cover using the recording to coach reps? Only if coaching was part of the purpose you stated when you asked. Mention it in the request, as in the example above, and do not reuse recordings for purposes the client was not told about.
