Termination Letter Switzerland: 10 templates for flat, job, insurance and subscriptions

Writing a termination letter: the 5 mandatory lines

You can spot a termination template from the UK by its references to the Housing Act and to notice periods that don't apply here: English tenancy law has as much to do with Switzerland as London weather has with Bern. In Switzerland, the Code of Obligations (CO) governs employment and tenancy contracts, the Insurance Contracts Act (ICA) covers insurance, and each canton approves its own termination form for flats.

The biggest trap: a termination is a declaration that takes effect on receipt. What counts is not the date on your letter but the day it reaches the recipient. Post a notice for the end of December by A-Post on 30 September and you are often one day late, and stuck in the contract until the next possible date.

You can't end a tenancy by e-mail: without a handwritten signature the notice is void (CO Art. 266l and 266o). For an employment contract, a verbal resignation is valid (CO Art. 335), but impossible to prove in a dispute. Basic rule: in writing and, whenever a deadline is running, by registered mail. Exception for subscriptions: some providers don't accept letters at all (see below).

If your notice on a flat names a date that is too early, it isn't void: it simply takes effect on the next possible date (CO Art. 266a para. 2). To make that clear for other contracts too, add "or alternatively on the next possible date" to line 4. With all five lines, your notice is clear and provable:

1. Sender with full address – First and last name, street, postcode and town. Family home: with the express consent of your spouse; safest is for both to sign (CO Art. 266m).
2. Recipient with exact name – Not "To the management", but the exact name of the property management or company.
3. Contract reference – Contract number, policy number or property address. The recipient cannot refuse a termination, but can dispute an unclear one.
4. Termination date – "I hereby give notice for [date], or alternatively for the next possible date". Not "with immediate effect".
5. Handwritten signature – Mandatory for residential and commercial premises (CO Art. 266l), elsewhere your best evidence. Only a qualified electronic signature with a qualified time stamp is equivalent (CO Art. 14 para. 2bis); a scan or typed name is not enough there.

Lease termination letter: form & notice periods (CO Art. 266–266o)

As a tenant you don't need an official form, but your landlord does: without the form, the landlord's notice is void (CO Art. 266l para. 2 and 266o). Each canton approves its own form, and 17 cantons offer it as a download; in the Termination Navigator you'll find yours and the competent conciliation authority. You yourself give notice in writing, in a letter signed by hand; an e-mail is not enough.

Notice periods: In Obwalden, Zug and Appenzell Ausserrhoden the authorities set the customary termination date, according to the canton analysis of the ConvivaPlus Termination Navigator; for your canton it shows you what is documented and where to ask. For flats, a 3-month notice period applies to a customary local date; where there is no local custom, to the end of a three-month rental period (CO Art. 266c). Customary dates differ from place to place and are often in the tenancy agreement. What matters is that the notice reaches the landlord before the period begins, not the date you send it.

The married-couple trap: If the rented flat is the family home, one spouse can only terminate with the express consent of the other, even if only one is named in the tenancy agreement (CO Art. 266m). Safest is for both to sign. Without consent, the notice is void (CO Art. 266o). The same applies to registered partnerships.

Resignation letter: CO Art. 335–335c and what HR won't tell you

On sick leave you can resign yourself at any time. The protection period only shields you from notice by your employer, and only after probation (CO Art. 336c para. 1): during illness, accident, military service or pregnancy, the employer can't give notice, but you can.

Notice periods under CO Art. 335b and 335c: 7 days during probation, 1 month in the 1st year of service, 2 months from the 2nd to the 9th year, 3 months from the 10th year, each to the end of a month. Many collective agreements (e.g. the hospitality agreement L-GAV) set different periods. Check your employment contract and the applicable collective agreement.

Form: Terminating an employment contract is free of formal requirements; a verbal resignation would be valid (CO Art. 335 para. 1). Never do it that way: in a dispute you have no proof, and the employer can claim to have heard nothing.

Cancelling health insurance and other policies: the deadline many people miss

Post your health insurance cancellation on 30 November and you're too late: it must be at the insurer's on that day. The post takes 1–3 working days, so send it by registered mail at least a week beforehand. The legal basis is HIA Art. 7 para. 2: one month's notice after the premium announcement, to the end of the year. With the standard deductible in the standard model, you can also switch with three months' notice to 30 June (para. 1). And the old insurer only releases you once the new one confirms that you are insured without interruption (para. 5).

For supplementary insurance (ICA), the notice period in your policy applies; there, only you, not the insurer, have the ordinary right of cancellation under Art. 35a ICA (para. 4). Caution: many supplementary policies renew automatically for a year if you miss the deadline. Then you pay another full year of premiums.

Car, household contents, liability insurance: your policy states the notice period. Even a multi-year contract can be cancelled under Art. 35a ICA with 3 months' notice to the end of the third year. Check your policy to see whether the insurance year starts on 1 January or on the start date of the contract: that's the most common mistake.

Cancelling subscriptions: Mobile, gym, streaming & magazines

Of all things, it is your mobile plan where a termination letter can go nowhere: Sunrise only accepts cancellations by phone or live chat and says so itself: "Written cancellations by mail, fax or e-mail are not valid." The notice period there: two months to the end of a month, at the earliest to the end of the minimum term (sunrise.ch, as at 1 November 2026). At Swisscom, for most plans the notice must arrive at least 60 days before the contract ends. Your contract and the terms and conditions always decide.

Gyms: many studios work with annual contracts that renew automatically; the notice period is in the contract. Some chains only accept cancellation by registered mail or in person: read the terms.

Streaming (Netflix, Spotify, Disney+): with monthly payment you cancel online at any time, to the end of the current billing period. No letter needed. With annual plans there's usually no refund, but you can keep watching until the end.

Notice periods in Switzerland at a glance

A shop lease takes six months' notice (CO Art. 266d), twice as long as a job after ten years of service. In a tenancy, your contract can only provide for longer periods (CO Art. 266a). In an employment contract, shorter periods are also possible by written agreement or collective agreement, but under one month only by collective agreement and in the first year of service (CO Art. 335c para. 2).

Common mistakes: the 7 that delay or void a Swiss termination

A registered letter costs CHF 5.80; three extra months' rent at CHF 2,100 a month costs CHF 6,300. These seven mistakes make a notice ineffective or push it back by months:

Mistake 1: Counting from the sending date instead of the receipt date. The notice must have arrived by the deadline. Posting it by A-Post on the last day is too late.

Mistake 2: Wrong form for a flat. Tenants give notice in a letter signed by hand, an e-mail is not enough; landlords must also use the official form. Otherwise the notice is void (CO Art. 266l, 266o).

Mistake 3: No spousal consent. For a family home you need the express consent of the other spouse (CO Art. 266m). Without it, the notice is void.

Mistake 4: No registered mail. In a dispute you can't prove the notice arrived.

Mistake 5: Wrong notice period in an employment contract. Many assume 1 month although they have been employed for 3 years (correct: 2 months). Or the collective agreement says something else.

Mistake 6: Giving notice by e-mail for residential or commercial premises. Void; even as an "advance notice" or "for information" it keeps no deadline. Only a qualified electronic signature with a qualified time stamp is equivalent to a handwritten signature (CO Art. 14 para. 2bis).

Mistake 7: Not asking for confirmation. Without written confirmation from the recipient, your only evidence is the registered mail receipt, and that proves delivery, not content.
