Why are some letters yellow?
The yellow color serves as a warning signal and indicates a formal delivery. Courts and government agencies in Germany use yellow envelopes to ensure that important legal documents stand out and are not overlooked. The legal basis for this is Section 166 of the Code of Civil Procedure.
Upon delivery, the mail carrier records the date and time on the yellow envelope. This delivery certificate serves as proof that you have received the letter—regardless of whether you open or read it.

Who sends yellow letters?
Various institutions use yellow letters for formal deliveries:

• Local courts: payment demands, enforcement orders, divorce petitions
• Police and public prosecutor’s office: summonses to testify
• Traffic violation offices: notices of fines for traffic violations
• Tax offices: tax assessment notices and notices of enforcement
• Bailiffs: Notices of Seizure

Does a yellow letter always contain bad news?
Not necessarily. Yellow letters contain important legal information that isn’t necessarily negative. For example, they may include a summons to appear as a witness or inform you of court dates. The yellow color simply indicates that the content is legally relevant and requires your attention.

How to Respond Correctly to a Yellow Letter
Act immediately: Open the letter right away and read it carefully. Ignoring it won’t help—the letter is legally considered delivered.
Note deadlines: Enter all specified deadlines in your calendar. For payment demands, you usually have two weeks to file an objection.
Keep the envelope: The delivery date on the yellow envelope is important for calculating the deadline. Do not throw it away.
Check the validity: Verify whether the claims or demands are actually valid. Courts often review only the form, not the content.

What happens if you ignore it?
The consequences can be serious:
• A payment order is followed by an enforcement order
• Failure to appear when summoned as a witness may result in a fine or detention
• Missed objection deadlines cannot be made up
• Enforcement measures such as bank account garnishments become possible

Even if you refuse to accept the letter or return it unopened, it is considered legally served. The deadline begins upon delivery.
