The conciliation authority is the first level of resolution of rental disputes.

Swiss federal law requires that the deposit be returned within the period established by law (generally 30 days from the end of the contract).

Key facts

What: Swiss Federal Rules on Deposit, Cancellation, Dispute
Where: Switzerland (federal law, also applicable Zug)
Who: Tenants, landlords, conciliation authority
Deposit: Maximum 3 months of rent
Deadline: 30 days to challenge the authority

The security deposit is limited by Swiss federal law to a maximum of three months' rent, and must be paid into an escrow account in the name of the tenant, not the landlord. This principle protects the tenant from the confiscation of money. When a cancellation is received, it must be communicated in writing on an official cantonal form — an informal communication is not sufficient and can be challenged. If the tenant disputes the initial fee or considers the cancellation unfair, they have 30 days to appeal to the cantonal conciliation authority. These rights are guaranteed by Swiss federal law and apply in every canton, including Zug.

Federal law sets precise rules to protect both parties: the landlord gets financial guarantees (the deposit), the tenant gets protection from unjustified withholding of the deposit, and from arbitrary recourse to dismissal. Knowing these rights and duties is essential

Operational details

Dispute the initial fee

When a tenant considers the rent proposed by the landlord to be unfair, he has the right to dispute it with the cantonal conciliation authority. The dispute must be submitted within 30 days of signing the contract. This term is peremptory: if it passes without the tenant having recourse, the right to dispute is extinguished. The authority examines the claims of both parties, assesses whether the rent reflects the objective conditions of the lease (location, square footage, state of the property) and can issue a binding decision or not depending on the canton's procedure. If the tenant considers the rent excessive compared to the local market, they submit supporting documents (comparable listings, agency ratings) and the conciliation authority assesses the appeal. It is not common practice because the fees usually result from negotiations between the parties, but the right to dispute exists and is important for those who believe they have signed a contract under unbalanced conditions.

Cancellation and rights of the parties

The cancellation of the landlord (and sometimes the tenant) must be communicated in writing and must comply with specific procedures. According to Swiss federal law, the cancellation must take place on an official form of the canton, not on a simple informal letter. Failure to comply with the prescribed form may render the cancellation invalid. Federal law also governs the terms and

Key points

What to do concretely

Before signing a lease agreement, read the terms carefully and check that the deposit does not exceed three months' rent. Request in writing that the money will be deposited into a locked account in your name (tenant) and obtain a bank receipt as proof. Keep all documentation related to the deposit for possible future disputes. If the landlord requires a rent that you consider too high, you have 30 days from signing to present a complaint to the conciliation authority of your canton (Zug, if resident). Collect comparable evidence: public advertisements for similar houses in the area, real estate agency reports, official data on local living costs. The stronger your evidence, the more convincing your appeal will be. When receiving a notice of termination, carefully check that it is written on the official form of the canton and that it has been sent properly (registered or certified delivery). If you consider the notice illegitimate or irregular in form, inform the conciliation authority immediately. Do not ignore a notice without appealing: if you do not act within the prescribed time, the notice becomes valid. At the end of the rental period, the landlord must return the deposit to you within the time limit set by law (usually 30 days from the end of the contract). If the landlord withholds the deposit alleging damages, they must provide a written justification with attached documents (repair quotes, invoices). If you disagree with the deductions, write a registered letter to the landlord explaining your objections and then appeal to the conciliation authority.
