Often, debtors only pay after the payment term. Sometimes debtors only pay after they have taken all the time they can and you have heard every conceivable excuse there is. And sometimes they still don’t pay. The only remaining option is a procedure.
Collection costs
Keep in mind that consumers must be sent a correct ‘fourteen days’ letter before these collection costs are due on the basis of Article 6:96 Dutch Civil Code. That often goes wrong. The correct amount of collection costs must be stated in this letter. And the term is fourteen days from the day after receipt of the letter, not from the date of receipt and certainly not from the date of sending. You can read more about this and about the obligation to provide information and the burden of proof regarding the chargeability of collection costs on jurisprudence.nl in the judgment with reference ECLI: NL: HR: 2016: 2704.
