Of all the rules in German employment law, this is the one expat employees most often miss — and the one that costs the most. Under § 4 of the Kündigungsschutzgesetz, you must file your wrongful-dismissal claim (Kündigungsschutzklage) at the competent labor court within three weeks of receiving the written dismissal. If you miss the deadline, § 7 KSchG kicks in: the dismissal is deemed valid by force of law, regardless of how unlawful it was in substance.
When does the clock start?
The clock starts the moment the dismissal letter physically reaches your sphere of control — typically the moment it is delivered to your mailbox (Briefkasten) or handed to you. It does not start when the employer signed the letter, nor when it was mailed. Note the exact date and, where possible, keep the envelope with the postmark.
If you are abroad when the letter is delivered, the clock still starts when it arrives at your German address. That is a particular trap for expat employees on extended trips home or on holiday.
What “filing” means
“Filing” means that the written claim has physically arrived at the labor court before the end of the three-week period. Sending it on the last day is risky. We typically file electronically through the secure attorney-court channel (beA), which gives a timestamped receipt and removes any doubt.
Why the deadline is so unforgiving
The German legislature wanted to create legal certainty for both employer and employee within a short window. The flip side is that exceptions are extremely narrow. § 5 KSchG allows an out-of-time application only if you were prevented from filing through no fault of your own — for example, severe hospitalisation that began before the dismissal arrived and made it impossible to act. The case-law bar is high; “I didn’t know about the deadline” or “I thought my employer would change their mind” never succeed.
What does the deadline cover?
It covers every reason the dismissal could be invalid — substantive lack of justification, formal defects (no wet-ink signature, wrong signatory), missing consent of the works council, special-protection violations, AGG discrimination. All of these arguments are lost if you don’t file in time.
What you can lose if you miss it
- The right to challenge the dismissal at all.
- Any severance negotiation leverage. Employers know the deadline and stop responding once it has passed.
- Wage claims for the period after the dismissal (Annahmeverzug), which are downstream of an effective dismissal challenge.
- Often: your German residence permit, if it was tied to your specific job and you had hoped to challenge the dismissal in order to keep working.
How the deadline actually runs — three worked scenarios
- Letter handed to you at the office on Friday at 5 pm. The clock starts that Friday. The deadline is three calendar weeks later, on the same weekday — the following Friday three weeks out. File at the labor court by that date.
- Letter dropped in your mailbox on Saturday morning. Even though no one was there to read it, the law treats it as received the moment it could normally be retrieved (i.e. Saturday or the following Monday, depending on case-law). Be conservative: count from Saturday.
- Letter sent by registered post — you collect it from the post office the following Wednesday. Receipt is the moment the letter physically reaches your sphere of control. The post-office collection date is what counts, not the notice slip date — though most courts will read it conservatively against the employee, so plan to file early.
What happens to a dismissal that you don’t challenge in time
The deemed-valid effect of § 7 KSchG applies to all grounds — form defects, missing works-council consultation, special-protection violations, AGG discrimination, even outright forgery of the signature. The only escape is § 5 KSchG, which allows out-of-time filing where you were prevented from filing through no fault of your own. The bar is high: serious hospitalisation, demonstrably no way to know about the dismissal at all, or a similar extreme circumstance. “I didn’t know there was a deadline” never succeeds.
Quick decision tree
- Did you receive a written dismissal letter? — Note the date and call us today.
- Did you receive only an email or WhatsApp? — The form is defective but you must still file within 3 weeks to preserve the defect.
- Did you receive a termination agreement instead? — Different rules apply; the 3-week deadline doesn’t run, but signing waives almost everything. Get advice before signing.
- Has more than 3 weeks already passed? — Call us anyway. § 5 KSchG out-of-time relief is narrow but worth checking.
