When to call us

Are you facing one of these situations?

A criminal defense is often decided before the first hearing. What is said or signed in the first hours weighs on the rest of the proceedings.

Have you received a summary penalty order? You have only ten days to file an objection (Swiss summary penalty order, you have ten days).

Where the case also involves a civil dispute or talks with the other side, both move forward within the same matter (Litigation and negotiation).

Frequently asked questions

Before you call

Do I have to answer police questions without a lawyer?

No. At the start of the first hearing, the police or the Public Prosecutor must inform you that you may refuse to make a statement and that you may call a defense lawyer (Art. 158 CrimPC). A hearing conducted without that information cannot be used against you. Call us before you answer the summons. That is often where the strategy is decided.

I have received a summary penalty order (ordonnance pénale). What should I do?

You have ten days to file a written objection with the Public Prosecutor (Art. 354 CrimPC). Without an objection, the summary penalty order becomes a final judgment, with an entry in the criminal record where applicable. A defendant does not need to give reasons. We review the order with you before the deadline and advise whether to object.

How much does a criminal defense cost?

A first 45-minute consultation costs CHF 200, deducted from the first invoice if you retain us. After that, an hourly rate or a fixed fee per phase (hearing, objection, trial), agreed in writing before any step is taken. Where means are limited, we look at court-appointed defense and legal aid.

I have been defrauded. Is a criminal complaint worth filing?

Yes, if it is filed quickly and built properly. In Switzerland, a complaint for fraud (Art. 146 SCC) or money laundering (Art. 305bis SCC) allows the Public Prosecutor to freeze funds that can still be traced, to obtain data from banks and platforms and to coordinate with foreign authorities. We draft the complaint with the exhibits and the requests for measures. How the complaint is built largely determines how it is handled.

Do you intervene in an emergency, such as an arrest, a hearing or a search?

Yes, in Geneva and throughout French-speaking Switzerland. Call +41 22 512 76 00. Your lawyer may attend police questioning (Art. 159 CrimPC) and the taking of evidence by the Public Prosecutor (Art. 147 CrimPC). Outside office hours, leave a message and we will call you back as soon as possible.
