Acknowledgment of debt between individuals

An acknowledgement of debt between individuals is a document with which one person (called ‘debtor’) formally acknowledges owing a sum of money to another person (called ‘creditor’). This document must be entirely written by the debtor and kept by the creditor. Failing this, the debtor must imperatively write ‘OK’ or ‘approved’ when they proceed to sign the document.

According to Article 1326 of the Belgian civil code, certain matters must be stated in order for the document to be legal.

The acknowledgment of debt must therefore:

  • Be in writing, dated and signed by the debtor
  • Specify the last names, first names and dates of birth of the debtor and creditor
  • Indicate in letters and in numbers the amount owed

Other matters such as the applicable interest rate or the date at which the payment is due can also be added if agreed upon by both parties.

In case of any dispute, the acknowledgment of debt between individuals will allow the creditor to demand repayment before the competent courts in this matter.
