Kündigungsschutzklage: How to File a Dismissal Claim in Germany

A Kündigungsschutzklage is the formal claim an employee brings before the Arbeitsgericht (labour court) to challenge a dismissal. It exists for one narrow purpose: asking the court to declare that the Kündigung did not end the employment relationship.

Everything else about the case, whether the dismissal was actually justified, what a settlement might look like, how long the case takes, sits downstream of one fact. The claim itself has a three week deadline that starts the moment the dismissal letter reaches you. This page walks through that deadline, what filing actually involves, and what the case looks like once it is underway.

Why the calendar matters more than the merits

Whether a dismissal was actually justified is a separate question from whether you still have the right to have it examined at all. German law does not give an employee an open ended window to decide whether to fight a Kündigung.

Once the three week deadline in § 4 KSchG passes, the reason for the dismissal generally stops mattering, because § 7 KSchG deems the dismissal valid regardless of how weak the underlying grounds were. A Kündigungsschutzklage is a filing deadline problem before it is a legal merits problem.

The three week deadline under § 4 KSchG

§ 4 KSchG requires an employee who wants to dispute a dismissal to bring a claim before the Arbeitsgericht within three weeks of Zugang, meaning the day the written dismissal actually reaches the employee. The date printed on the letter and the day it is opened or read are both irrelevant. Only the day it arrives, typically in the employee's mailbox or hand, starts the clock.

The three weeks are calculated under the general civil law rules in §§ 187 and 188 BGB. The day of Zugang itself does not count toward the period, and the deadline then ends on the same weekday three weeks later.

Worked example. An employee receives a signed dismissal letter on Monday, 3 August 2026. The day of receipt does not count toward the period, so the three weeks run from Tuesday, 4 August, and the deadline falls on Monday, 24 August 2026, the same weekday three weeks after Zugang. A claim reaching the Arbeitsgericht on 25 August, even a single day late, is out of time absent one of the narrow exceptions below.

What happens if you miss the deadline: § 7 KSchG

§ 7 KSchG is blunt about the consequence. Where the invalidity of a dismissal is not asserted in time, the dismissal counts as legally effective from the beginning. That applies even to a dismissal a court would otherwise clearly have rejected, for example one issued to a long serving employee with no stated reason at all.

This is why the three week period matters more than the substance of the dismissal in the first instance. An employee with an objectively strong case who files in week four has, in almost every situation, no claim left to bring.

The narrow escape hatch: nachträgliche Zulassung under § 5 KSchG

§ 5 KSchG lets a court admit a late claim, but only where the employee was prevented from filing within the three weeks despite using all the care that could reasonably be expected given the circumstances. This is a narrow standard aimed at genuine impossibility, not at forgetting the deadline or delaying while deciding whether to act.

The statute separately protects a pregnant employee who learns of the pregnancy only after the deadline has passed, through no fault of her own, since that fact changes the legal analysis of the dismissal itself.

Treat § 5 KSchG as a safety net for a genuine emergency, such as serious illness or being unreachable through no fault of your own, not as a routine second chance to file late.

Before you file: does the KSchG even protect you?

A Kündigungsschutzklage can be worth bringing whether or not general KSchG protection applies, since the three week deadline, the written form requirement, and several special protections exist independently of company size or tenure. Whether the KSchG's substantive protection against an unjustified dismissal applies at all still depends on two separate conditions.

§ 1 KSchG generally requires more than six months of unbroken service with the same employer before its protection attaches. § 23 KSchG then sets a dual employee count: employers with five or fewer staff are exempt for anyone hired on or before 31 December 2003, and the exemption widens to ten or fewer staff for anyone hired after that date, with part time staff counted as 0.5 for up to 20 hours a week and 0.75 for up to 30 hours.

See dismissal by your employer for the full detail on the Wartezeit, the dual headcount test, and the three recognized grounds for a socially justified dismissal. This page focuses on the claim itself once you have decided to bring one.

How to file a Kündigungsschutzklage

A Kündigungsschutzklage is filed with the Arbeitsgericht covering the place where the employee ordinarily works, or the employer's registered seat. Filing does not require a lawyer. § 11 ArbGG allows parties to conduct labour court proceedings themselves at first instance, and most courts operate a Rechtsantragsstelle, a registry office where a claim can be dictated orally for the record instead of drafted in writing.

§ 496 ZPO, which applies to labour court filings through the general procedural rules, confirms that a claim may be submitted in writing or stated orally at the court registry for the record. In practice, many employees still use a lawyer even though one is not required, both because of the strict deadline and because a Kündigungsschutzklage is rarely just about the paperwork of filing it.

Filing needs, at minimum, the identity of both parties, a copy of the dismissal letter, and the date it was received, since that date is what the court checks first.

What happens next: the Güteverhandlung

Once a Kündigungsschutzklage is filed, § 54 ArbGG opens the oral proceedings with a Güteverhandlung, a conciliation hearing conducted by the presiding judge alone, without the two lay judges who sit on the full chamber. Its purpose is to discuss the entire dispute with both sides and explore a settlement before the case goes any further.

For disputes over the existence or termination of an employment relationship, § 61a ArbGG requires the case to be handled with priority, and the Güteverhandlung is generally scheduled within about two weeks of the claim being filed, unusually fast by German civil litigation standards.

A large share of Kündigungsschutzklage cases end at this first hearing, typically with a Vergleich, a settlement in which the employer agrees to pay a sum and the employee agrees the employment has ended on an agreed date, rather than being reinstated.

If conciliation fails: the Kammertermin

Where the Güteverhandlung does not resolve the dispute, or a party fails to appear, the case proceeds to a contested hearing, either immediately or on a new date set promptly under § 54 ArbGG. That hearing, the Kammertermin, is heard by the full chamber described in § 16 ArbGG: one professional judge as chair, plus one lay judge (ehrenamtlicher Richter) drawn from employee representatives and one from employer representatives.

The Kammertermin is where evidence is taken and the substantive question, whether the dismissal was validly grounded under § 1 KSchG, is actually argued and decided if the parties still have not settled. Many cases still settle at or before this stage, since the pressure that made the Güteverhandlung attractive, an uncertain outcome and mounting cost exposure, only grows once a full contested hearing is imminent.

The cost rule that changes the calculus: § 12a ArbGG

Ordinary German civil litigation follows a loser pays rule for both court costs and the winning side's lawyer. § 12a ArbGG carves first instance labour court proceedings out of that second part. At the Arbeitsgericht, each side bears its own lawyer's fees regardless of who wins the case.

This matters for a Kündigungsschutzklage in a very practical way. An employer weighing whether to fight a weak dismissal to judgment cannot recover its own legal fees even if it wins, and an employee bringing a claim does not risk paying the employer's lawyer if the claim fails, only their own. That asymmetry is one of the reasons German employment litigation settles as often as it does, since both sides are already paying their own lawyer regardless of outcome, so a negotiated number often beats gambling on a verdict neither side can fully monetize even by winning.

Court fees themselves work differently from lawyer's fees and are typically lower where a case ends in a Vergleich rather than a judgment, a further, separate incentive toward settlement.

Prozesskostenhilfe and legal expenses insurance

Employees who cannot afford a lawyer or the limited court costs can apply for Prozesskostenhilfe, state legal aid available in labour court proceedings under § 11a ArbGG through the general Prozesskostenhilfe rules in the Zivilprozessordnung. Approval depends on income, savings and the claim having a reasonable prospect of success. It is not automatic simply because an employee has been dismissed.

Many employees instead rely on a Rechtsschutzversicherung, private legal expenses insurance, where they already hold a policy that covers employment disputes. Cover typically requires the policy to have existed before the dismissal and often carries its own waiting period, so checking an existing policy is worth doing in the same first days as calendaring the three week deadline.

What a Kündigungsschutzklage realistically ends in

The formal relief a Kündigungsschutzklage seeks is a declaration that the dismissal did not end the employment relationship, which in principle restores the job. In practice, the large majority of these claims end in a negotiated settlement rather than a court order, typically a payment from the employer to the employee in exchange for the employee accepting that the employment is over on an agreed date.

Where a settlement includes a payment, its size is usually discussed against a common convention, not a legal entitlement. Roughly half a month's gross salary for each year of service is a frequently used starting point in negotiations, though nothing in the KSchG requires an employer to pay that or any other amount. The actual figure in any given case depends on the strength of the dismissal, how far the case has progressed, and what each side is prepared to accept. See severance pay for how that convention is typically calculated and where it comes from.

Reinstatement remains available where a case is actually decided by judgment rather than settled, and it does happen, particularly where an employer's grounds are clearly deficient and it declines to settle. A realistic starting expectation going in, though, is a negotiated outcome rather than a return to the same desk.
