Longer than most parties expect, and any lawyer who promises you a date is guessing. Duration is driven by the stages every case passes through — conciliation, written exchanges, evidence, judgment, possibly appeal — and above all by how contested the facts are. Preparation and settlement strategy are the levers you actually control.

The stages every case passes through

A Swiss civil claim does not go straight to a judge. Most claims start before a conciliation authority, whose job is to attempt settlement; only if that fails does the case move to court. There, the parties exchange written submissions — statement of claim, answer, and frequently a second round — each drafted carefully, because what is not pleaded properly may not be considered.

Then comes the phase that most often decides the calendar: evidence. Documents are quick; witnesses take longer; and where the dispute turns on technical or valuation questions, a court-appointed expert opinion is regularly the single longest stretch of the whole proceeding. After judgment, either party can appeal, and an appeal restarts substantial parts of the clock.

What actually drives the duration

Two cases filed the same week can end years apart. The differences are rarely mysterious:

• How contested the facts are. A dispute about the meaning of a clause, decided on documents, moves far faster than one about defective machinery or company valuation that needs experts.
• The scope of the fight — multiple parties, multiple claims and counterclaims multiply submissions and evidence.
• Procedural skirmishing: challenges to jurisdiction, disputes over evidence and other interim battles each add their own loop.
• The court's workload, which the parties do not control.
• Appeals — a party determined to exhaust every instance can stretch almost any case.

Ask your lawyer for the honest version of this list applied to your dispute, not for a date. The realistic answer is a range of scenarios, each with a price tag.

What shortens a case

You cannot compress the court's calendar, but you can avoid feeding the drivers above. Cases built on a clean documentary record move faster than cases that depend on witnesses and reconstructed memories — which is an argument for contract discipline long before any dispute. Claiming only what you can prove, rather than everything you can imagine, narrows the evidence phase. Forum and arbitration clauses agreed at contract signing can route future disputes into a faster track than the default.

Above all: most commercial disputes end in settlement, not judgment. Each stage — conciliation, the first exchange, the evidence phase — is a fresh window in which a prepared party can take a good exit. Keeping your settlement economics current throughout the case is usually worth more than any procedural acceleration.

How these factors play out in your dispute is a question worth discussing with a lawyer before you commit to the road.
