Objecting to a Default Summons: Deadlines and Proper Procedure

A yellow envelope from the court usually causes a fright. However, a default summons (Mahnbescheid) does not mean that the claim has already been judicially reviewed. The court only checks the formal details of the applicant. If the claim appears unjustified or the costs seem too high, you must act quickly: you must object to the default summons. You can find more comprehensive basic information in our Debt Collection and Default Summons Guide.

1. The Most Important Rule: The 2-Week Deadline

As soon as the default summons is served, the clock starts ticking.

  • You have two weeks to file an objection.
  • The deadline begins on the day of delivery (date on the yellow envelope).
  • If no objection is made, the creditor can apply for a writ of execution (Vollstreckungsbescheid), which can act like a legally binding judgment.

2. How to Object Correctly

A form for the objection is usually enclosed with the default summons.

  • Partial objection: If the main claim is correct, but the interest or debt collection costs are excessive, you can also object to the summons only partially.
  • No justification necessary: You do not have to justify your objection to the dunning court for the time being.
  • Text form: The objection must be received by the competent court in written form.

3. Content Control and Invalid Clauses (Section 307 BGB)

Default summons are frequently based on contracts with invalid clauses. This is where the content control according to Section 307 BGB applies:

  • Provisions in standard contracts are invalid if they unreasonably disadvantage the contractual partner contrary to the requirements of good faith.
  • An unreasonable disadvantage may exist if the underlying contract clause is not clear and understandable (transparency requirement).
  • Clauses that restrict essential rights in such a way that the purpose of the contract is jeopardized are invalid in case of doubt.
  • If the claim was triggered by such an invalid clause, the default summons is often legally assailable.

4. What Happens After the Objection?

If you object in a timely manner, the automated dunning process is initially stopped.

  • The creditor must now decide whether to initiate contentious proceedings before a civil court.
  • Only in these proceedings will the substance of the claim be examined to see if it is actually lawful.
  • The creditor must then prove that they have properly fulfilled their obligations under the contract.
