Deadlines in social law: calculate objection, lawsuit and delivery fiction correctly

A notice from the Jobcenter or the health insurance fund lies in the mailbox — and suddenly a clock you cannot see is ticking. Anyone who misses a deadline loses rights, often irretrievably. This guide explains the most important deadlines in social law, shows you how to calculate them correctly, and what to do when the calendar is already getting tight.

The essentials in 30 seconds

• Objection (Widerspruch): one month after notification of the decision (§ 84 SGG).
• Lawsuit (Klage): one month after receipt of the objection decision (§ 87 SGG); three months for service abroad.
• Delivery fiction (Zugangsfiktion): a notice sent by post is deemed received on the third day after dispatch (§ 37 Abs. 2 SGB X).
• Review request under § 44 SGB X: retroactive up to four years — the rescue when the objection deadline has expired.
• Restoration of the previous status (Wiedereinsetzung in den vorigen Stand, § 67 SGG): two weeks after the obstacle disappears, at most one year.
• Urgent application (Eilantrag): possible at any time, provided urgency still exists (§ 86b SGG).

Why are deadlines so critical?

Deadlines in social law are not a formality but a hard limit. If the objection deadline expires, the notice becomes legally final (bestandskräftig) — it then applies even if its content is wrong. And that happens faster than you think: a hospital stay, a holiday, an envelope left lying on the kitchen table — and the four weeks are gone.

Example: Torsten, 52, top-up earner with a warehouse job

Torsten works part-time in a warehouse, his income is not enough to live on, he tops up with Bürgergeld. On 15 March 2026 he suffers a slipped disc during his shift and is taken to hospital immediately. He spends two weeks on the ward, then almost a week at his sister's because he cannot care for himself alone. When he enters his flat on 29 March, he finds in the mailbox a revocation and reimbursement notice (Aufhebungs- und Erstattungsbescheid) dated 12 March for 1,420 euros. The Jobcenter assumes he failed to report overtime.

Torsten asks himself: is the deadline already over?

Calculation: the notice was posted on 12 March. The delivery fiction (Zugangsfiktion, § 37 Abs. 2 SGB X) takes effect three days later, i.e. on 15 March 2026 — from then on the notice is deemed announced. The one-month period of § 84 SGG starts running, under § 187 Abs. 1 BGB, with the end of 15 March. It ends, under § 188 Abs. 2 BGB, with the end of the day in the following month bearing the same number: 15 April 2026.

So Torsten still has roughly two and a half weeks — and because he can prove that he could not empty the mailbox due to his hospital stay, he also has good cards for restoration of the previous status (Wiedereinsetzung) should the deadline really become too tight after all.

Your concrete rights

1. Objection deadline — § 84 SGG Against any burdensome notice from a social benefit provider you can lodge an objection (Widerspruch) within one month of notification. The deadline starts the day after notification (§ 187 Abs. 1 BGB) and ends with the end of the corresponding day in the following month (§ 188 Abs. 2 BGB). If the end of the deadline falls on a Saturday, Sunday or public holiday, it shifts to the next working day (§ 26 Abs. 3 SGB X).

2. Lawsuit deadline — § 87 SGG After an objection decision (Widerspruchsbescheid) you have one month to file a lawsuit (Klage) at the social court (Sozialgericht, SG). For service abroad (§ 87 Abs. 1 Satz 2 SGG) the deadline extends to three months. The same calculation rules under §§ 187, 188 BGB apply.

3. Delivery fiction — § 37 Abs. 2 SGB X (and § 4 VwZG for formal service) A notice is deemed received on the third day after dispatch by post — unless you can prove that it arrived later or not at all. Example: dispatch on 12 March 2026 → delivery fiction on 15 March 2026 → start of period 16 March → end of period 15 April 2026. The envelope with the postmark is therefore your most important piece of evidence — keep it.

4. Review request — § 44 SGB X If the objection deadline has expired, not all is lost. With a review request under § 44 SGB X you can still achieve, retroactively for up to four years, that an unlawful notice is revoked and unlawfully unpaid benefits are paid in arrears. The application can be informal.

5. Restoration of the previous status — § 67 SGG If the deadline was missed without fault (hospital stay, postal delivery error, acute psychological crisis), you can apply for restoration. You have two weeks after the obstacle disappears to file the application and at the same time make up the missed action (the objection or the lawsuit). The absolute upper limit is one year from the end of the deadline.

6. Urgent application — § 86b SGG When bare existence is at stake (rent, electricity, food), you can file an urgent application at the social court parallel to the objection or lawsuit — in theory at any time. However, the special urgency must still exist at the moment of decision; whoever waits too long risks rejection of the urgent application because the court may assume that it is no longer that urgent.

Recent case law

The Federal Social Court (Bundessozialgericht, BSG) has repeatedly clarified that the three-day delivery fiction only applies if the authority can actually prove the time of postal dispatch. If the letter is only put on its way at the weekend and the post in fact delivers it later, receipt may shift [URTEIL-REFERENZ].

The Higher Social Court (Landessozialgericht, LSG) has emphasised in several decisions on restoration under § 67 SGG that even a serious illness or longer hospital stay can constitute an obstacle without fault — provided the affected person was not in a position to commission a representative (relatives, advice centre) to safeguard the deadline [URTEIL-REFERENZ].

The Federal Constitutional Court (Bundesverfassungsgericht, BVerfG) in established case law emphasises the right to effective legal protection (Art. 19 Abs. 4 GG): deadlines must not be interpreted in a way that effectively makes access to courts impossible for affected persons. Doubts in calculating deadlines must therefore be resolved in favour of the citizen [URTEIL-REFERENZ].

How to proceed now

Step 1 — Check the date of the notice and postal dispatch Note the date on the top of the notice and — if still available — the postmark on the envelope. Both dates may differ; decisive for the delivery fiction is the actual postal dispatch.

Step 2 — Apply the delivery fiction Add three days to the postal dispatch date. Example: dispatch on 12 March, then the notice is deemed received on 15 March. Important: this fiction can be rebutted if you can prove that the letter arrived later (postmark, witnesses, post tracking).

Step 3 — Mark the end of the deadline in the calendar Add one month to the day of receipt. The period starts on the day after, the end is the same calendar day of the following month. Example: receipt 15 March → end of period 15 April. If 15 April falls on a Sunday, the end shifts to Monday, 16 April.

Step 4 — Keep the envelope The envelope with postmark is your most important piece of evidence. File it together with the notice. Without the envelope, you later argue with the authority about the receipt date — and you often lose that argument.

Step 5 — File the objection by registered letter or fax Send your objection by Einwurfeinschreiben (registered letter into mailbox), fax with transmission report or via the electronic authority mailbox. An e-mail without qualified signature is risky. Always keep a copy with proof of dispatch or receipt.

Step 6 — Secure proof of receipt With Einwurfeinschreiben you receive a delivery slip, with fax the transmission report, with personal handover an entry stamp on your copy. You need these proofs in case the authority later claims no objection arrived.

Avoiding typical mistakes

Mistake 1 — Underestimating holiday or absence The deadline runs even when you are at the beach. Whoever is foreseeably absent for longer should set up a forwarding order or give someone power to empty the mailbox. Mere absence is not automatically a reason for restoration.

Mistake 2 — Failing to document a hospital stay A hospital stay can justify restoration — but only if you prove it with admission certificate, discharge letter and, if necessary, medical certificate. Collect these documents immediately.

Mistake 3 — Overlooking missing or wrong appeal instructions If the appeal instructions (Rechtsbehelfsbelehrung) on the notice are missing or wrong (wrong authority, wrong deadline, incomplete form), the objection or lawsuit deadline extends under § 66 Abs. 2 SGG to one year. Check this text block at the bottom of every notice.

Mistake 4 — Phone calls instead of a written objection A call to the case worker stops no deadline. Even a verbal promise "we will sort it out" has no suspensive effect. Always file the objection in writing in parallel.

Mistake 5 — Thinking too late about the urgent application Whoever files an urgent application only weeks after learning of the notice often gets the answer: "Then it apparently is not so urgent." Act quickly as soon as an existence-threatening situation is foreseeable.

Frequently asked questions

When exactly does the deadline start?

The day of receipt itself does not count (§ 187 Abs. 1 BGB). The deadline starts with the end of the day of receipt and runs until the end of the day bearing the same number in the following month (§ 188 Abs. 2 BGB). Example: receipt on Tuesday, 15 March → start of deadline Wednesday, 16 March, 00:00 → end Wednesday, 15 April, 24:00.

What happens if the end of the deadline falls on a Saturday, Sunday or public holiday?

Then the end of the deadline shifts to the next working day (§ 26 Abs. 3 SGB X i.V.m. § 193 BGB). Example: end mathematically on Saturday, 18 April → actual end on Monday, 20 April.

Can I rebut the delivery fiction?

Yes. If you can credibly show that the notice arrived later than the third day after postal dispatch — for example through a different postmark on the envelope, a comprehensible postal delivery error or witnesses — the actual day of receipt applies. The authority then bears the burden of proof for the earlier receipt.

What can I do if I have already missed the deadline?

Three paths are open: first restoration of the previous status (Wiedereinsetzung, § 67 SGG) if the missed deadline was without fault. Second a review request under § 44 SGB X — retroactive for up to four years if the notice is materially unlawful. Third: check whether the appeal instructions were defective — in this case the extended one-year deadline under § 66 Abs. 2 SGG applies.

Does the three-day rule also apply at weekends?

Yes, the three days of the delivery fiction are counted calendar-daily, including Saturday and Sunday. If the calculated receipt date itself falls on a Saturday, Sunday or public holiday, however, it does not shift — the fiction applies on that day. Only the end of the actual objection or lawsuit deadline shifts, if necessary, to the next working day.
