Ordinary versus extraordinary termination in Swiss law

Whether it is a rented flat, an employment relationship, a gym membership or a long-standing services contract, anyone dissolving a contract in Switzerland inevitably encounters two fundamentally different legal mechanisms: ordinary termination and extraordinary termination.

Anyone who confuses these two forms or applies them wrongly risks formal errors, high financial claims or years of dispute before the conciliation authorities. While ordinary termination is the regular contractual exit, extraordinary termination is a sharp sword that only comes into play where serious grounds exist.

This comprehensive expert guide sets out in detail the precise difference, the statutory requirements under the Swiss Code of Obligations (CO) and the pitfalls in applying them.

1. Ordinary termination: the regular route to a fixed date

Ordinary termination is the standard case in Swiss civil law. It ends a contractual relationship in the regular way, once the agreed or statutory periods have run, as of a permissible date.

The core features of ordinary termination:

No reason required: for an ordinary termination, neither the tenant nor the employee nor the contracting party has to give a specific reason. The principle of freedom of contract allows either party to end the contract without justification, as long as the formal rules are observed.
Observing periods and dates: the termination only takes effect once a certain lead time (the notice period) has passed, as of a precisely defined point in time (the termination date).

Typical examples:

Tenancy law: terminating a flat in compliance with the 3-month notice period as of a locally customary date (Art. 266c CO).
Property insurance: terminating household contents insurance 3 months before the annual main renewal date under the VVG.
Employment law: terminating an open-ended employment contract in compliance with the statutory or contractual probation or basic notice periods (Art. 335c CO).

2. Extraordinary termination: the emergency exit from unreasonable conditions

Extraordinary termination (often also called immediate or early termination) is the exact opposite of the ordinary route. It breaks through rigid contract terms and periods ahead of time.

The core features of extraordinary termination:

A compulsory "good cause": an extraordinary termination can never be declared without a reason. The law (and Federal Supreme Court case law) requires an objectively serious ground to exist.
Continuation being unreasonable: the ground must be so serious that the terminating party cannot, in good faith (Art. 2 CC), be expected to continue the contractual relationship even one day longer until the next ordinary date.

Typical examples:

Tenancy law: serious defects in the flat that are not remedied despite repeated written warnings and a reasonable deadline (Art. 259b CO), or the death of the tenant.
Employment law: summary dismissal for serious misconduct (theft, assault, a serious breach of trust under Art. 337 CO).
Gym membership / contracts: a permanent unfitness for sport, evidenced by a medical certificate, following serious illness or an accident.

3. The differences side by side

To make the differences between the two forms of termination tangible, the following comparison is useful:

4. Pitfalls in practice: when the wrong form of termination is chosen

In reality it often happens that frustrated people declare an extraordinary termination even though no "good cause" exists in law — or, conversely, that someone misses a deadline and tries to wriggle out of the contract extraordinarily with threadbare arguments.

The consequence of a formal or substantive error: if you declare an immediate (extraordinary) termination of a gym membership simply because you no longer feel like training, the gym will reject the termination as a matter of law. With no good cause, the contract runs on in the ordinary way and you are left with the costs.
Conversion into an ordinary termination: courts sometimes argue that an ineffective immediate termination can at least count as an ordinary termination as of the next possible ordinary date — but you should on no account rely on this, as it depends on the case law and the area of law in question (tenancy versus employment law).

5. A guide: which route is right for your situation?

Before drafting a letter, ask yourself the following questions:

Is the regular date close? If you will reach the regular termination date in a few weeks or months anyway and can meet the notice period, always take the safe route of ordinary termination. It offers legal stability and leaves no room for drawn-out disputes.
Is there a serious, demonstrable exceptional case? (Total loss of health, defects that cannot be remedied, a breach of contract by the other side.) Only if you can back that ground up in black and white with evidence (certificates, records, registered-post receipts) does extraordinary termination come into consideration.

With this clear legal foundation you will always make the right choice in Swiss contract law and avoid expensive missteps.
