Swiss rental dispute: first steps and conciliation

Direct answer: what should you do in a rental dispute?

Preserve facts and deadlines, move communication into writing and state the outcome sought: repair, rent reduction, deposit release, termination challenge or settlement. Do not simply stop paying rent. If no solution is reached, contact the conciliation authority for the property’s location.

The first 24 hours

1. Create a chronology and preserve photographs, video and witnesses.

2. Save the lease, reports, invoices, letters and messages.

3. Send a short factual notice stating the request and a reasonable deadline.

4. Classify the issue: defect, rent, deposit, termination, sublet, early return or damage.

5. Check receipt and procedural deadlines immediately.

1. Defects and depositing rent

Under Article 259a, a tenant may seek repair, a proportionate rent reduction, damages or takeover of a third-party dispute for defects not attributable to the tenant; real-property rent may also be officially deposited. This is not the same as withholding payment.

Articles 259g–259h require a written reasonable repair period, advance warning and notice of the official deposit, followed by a claim to the conciliation authority within 30 days after the first deposited rent became due. Confirm the cantonal process before acting.

2. Termination and early return

Residential notice must be written. A challenge to a landlord termination must be submitted to the conciliation authority within 30 days of receipt under Article 273. For early return, Article 264 can release the tenant if a suitable, solvent replacement willing to take the lease on the same terms is proposed.

3. Deposit and handover

Separate bank release, damage claims and ancillary charges. The handover guide covers evidence and the deposit-return guide covers Article 257e. Do not sign a blank or unclear admission of liability.

4. Conciliation

The Federal Housing Office explains that a conciliation attempt precedes civil court proceedings for residential and commercial tenancy disputes. The authority has an independent chair and equal tenant and landlord representation; current cantonal addresses are published there.

5. One canonical process guide

The first 24 hours, when to use a lawyer or authority, common mistakes, conciliation and replacement tenants are sections of the same process, not competing pages. Before signing, use the lease review guide.

Last factual review: 4 August 2026. For legal deadlines, rely on the served document, cantonal guidance and individual advice where necessary.
