The Bottom Line
- Accidental overpayments create a clear legal right to reclaim funds under the Dutch principle of undue payment, even if the recipient enters financial distress.
- Businesses should be aware that recovering such funds can still require legal action, adding time and cost, especially when dealing with a party under legal administration.
- Crucially, the interest claimable on an overpayment is the standard statutory interest rate, not the higher commercial interest rate, as the claim arises from the payment error, not the original contract.
The Details
In a straightforward but instructive case, a real estate developer, LFB-Vastgoed Ontwikkeling B.V., accidentally paid a supplier more than double the invoiced amount. An invoice for installation work for approximately €3,200 was mistakenly paid with a transfer of nearly €6,800. This simple administrative error became complicated when the sole trader who received the funds had his assets placed under legal administration. When the administrator failed to return the overpaid amount of €3,615.48, LFB was forced to sue for its recovery.
The Amsterdam District Court sided with the developer, confirming that this was a textbook case of an undue payment (onverschuldigde betaling). This legal principle dictates that if a payment is made without a corresponding legal obligation, the recipient is required to return it. As LFB was only contractually obligated to pay the original invoice amount, the excess payment had no legal basis. The administrator did not contest the facts, making the court’s decision to order the repayment of the principal amount a formality.
The most significant legal insight from this case lies in the court’s ruling on interest. LFB initially claimed the higher statutory commercial interest rate, which is common in business-to-business disputes. However, the court corrected this. It reasoned that the duty to repay the money did not arise from the original commercial agreement for installation services. Instead, the obligation stemmed from the mistaken payment itself. Consequently, the claim falls outside the scope of a commercial transaction, and only the standard (and lower) statutory interest rate was awarded. This serves as a valuable reminder for legal and finance teams to apply the correct legal basis when calculating claims arising from administrative errors versus contractual breaches.
