Aanmaning

Aanmaning is a formal written demand for payment issued by a creditor when an invoice remains unpaid after the due date. It is part of the dunning process and aims to prompt settlement and clarify the outstanding amount.

A typical aanmaning includes: the names and addresses of creditor and debtor; reference to the original invoice; the amount still owed; any interest or costs charged since the due date; a new payment deadline (commonly 7 to 14 days); and instructions on how to pay. It may also mention consequences of continued non-payment, such as escalation to a collection agency or the initiation of legal proceedings, including possible involvement of a bailiff (deurwaarder).

The exact content and formal requirements vary by jurisdiction. In many Dutch-speaking countries the aanmaning is followed by further steps in the collection process; costs that a debtor can be asked to pay are sometimes regulated by law.

Purpose and effect: An aanmaning serves as a formal notice that the debt remains due and signals that the creditor intends to pursue further action if payment is not received. It creates a formal record of the request for payment and can influence subsequent proceedings or enforcement steps.
