Mutual legal assistance

Mutual legal assistance enables authorities in one state to support proceedings in another, especially in criminal matters but also in civil and administrative contexts. Switzerland handles requests under treaties and domestic law, with safeguards for sovereignty, due process, specialty, proportionality, and fundamental rights. Assistance may include taking testimony, transmitting records, freezing assets, or serving documents. Because Swiss banking, corporate, and digital data may be involved, requests are examined carefully and may be subject to appeal.
