Installment Payments in Debt Collection: Beware of Acknowledgment of Debt Clauses
Anyone who receives mail from a debt collection agency is often under considerable pressure. An installment payment is frequently offered as a supposed way out. But beware: An acknowledgment of debt (Schuldanerkenntnis) is often hidden in the small print of these agreements. What looks like a helpful solution at first glance can have far-reaching legal consequences and massively restrict your defense options against unjustified claims. You can find more basic information in our comprehensive debt collection guide.
1. What is an Acknowledgment of Debt?
An acknowledgment of debt is a contract that confirms the existence of an obligatory relationship. In the debt collection context, an "abstract" or "constitutive" acknowledgment of debt is usually sought.
- By signing, you generally legally confirm that the claim exists in full.
- A later objection that the original invoice was incorrect or the debt collection costs are too high is often legally excluded afterwards.
- In addition, the limitation period for the claim generally starts from scratch with an acknowledgment.
2. The Trap: Installment Payments Only Against Acknowledgment
Debt collection service providers almost always link the offer of an installment payment with an acknowledgment clause.
- The debtor not only signs a payment plan, but at the same time waives many defenses and objections.
- Additional fees are often charged for concluding the installment agreement, which can further increase the total debt.
- It is advisable to carefully check documents containing phrases such as "hereby irrevocably acknowledges the debt" beforehand.
3. Content Control of Acknowledgment Clauses (Section 307 BGB)
Whether such a clause in a pre-formulated installment agreement is legally valid depends on the content control for standard contract terms according to Section 307 BGB.
- Provisions are invalid if they unreasonably disadvantage the contractual partner (the debtor) contrary to the requirements of good faith.
- An unreasonable disadvantage can arise if the provision is not clear and understandable (transparency requirement).
- In case of doubt, a disadvantage is to be assumed if the provision restricts essential rights in such a way that the purpose of the contract is endangered.
4. Reacting Correctly to Debt Collection Claims
If you fundamentally acknowledge the claim but can only pay in installments, you should seek an agreement without a constitutive acknowledgment of debt.
- Partial payment with reservation: In case of doubt, only make payments subject to legal review so as not to create an automatic acknowledgment through conclusive behavior.
- Disputing the costs: If the main claim is justified but the ancillary costs appear excessive, explicitly object to the exceeding part.
