The Short Answer

You must file a lawsuit at the labor court within three weeks of receiving the written dismissal notice, claiming the dismissal is socially unjustified or invalid.

What the Law Says

German law sets strict deadlines and formal requirements for challenging unfair dismissals. The primary rule is found in the Protection Against Dismissal Act (KSchG).

To contest a dismissal as socially unjustified (sozial ungerechtfertigt) or otherwise invalid, you must file a claim at the local labor court (Arbeitsgericht). This is not optional — missing the deadline forfeits your right entirely.

The claim must be filed within exactly three weeks after the written dismissal notice reaches you. Weekends and public holidays count — only calendar days matter.

Your lawsuit must seek a 'declaration that the employment relationship has not ended' (Feststellung, dass das Arbeitsverhältnis durch die Kündigung nicht aufgelöst ist). It is not enough to simply object informally or complain to HR.

If your workplace has a works council (Betriebsrat), and you filed an objection with them before suing, you must attach their written opinion to your court filing.

Statutory Text

Will ein Arbeitnehmer geltend machen, dass eine Kündigung sozial ungerechtfertigt oder aus anderen Gründen rechtsunwirksam ist, so muss er innerhalb von drei Wochen nach Zugang der schriftlichen Kündigung Klage beim Arbeitsgericht auf Feststellung erheben, dass das Arbeitsverhältnis durch die Kündigung nicht aufgelöst ist.

What to Do

1

Get the written dismissal notice — oral dismissals are generally invalid, but you still need proof of receipt.

2

Count 21 calendar days from the day you received it — file your lawsuit on or before day 21.

3

Draft and submit a statement of claim (Klage) to your local labor court — include all facts, legal arguments, and supporting documents (e.g., contract, dismissal letter, works council opinion if applicable).

4

Consider hiring a labor law attorney (Fachanwalt für Arbeitsrecht) — many offer free initial consultations, and legal aid may be available.
