In Delft, with its vibrant student population and tight rental market around TU Delft and the city centre, deposit and key money are often confused. Legally, they differ fundamentally: deposit (CC 7:220) is a security sum for possible damage or overdue payments, which is refundable at the end of the tenancy. Key money is a one-time payment that does not fall under the same statutory protection. Landlords in Delft may not misuse deposit as a cover for prohibited key money, especially not for rooms in monumental buildings on Oude Delft or Phoenixstraat.
Problem: A landlord in Delft deducts €250 'key costs' from the deposit without an invoice or proof. Solution: Demand a detailed settlement within 30 days after departure. No response within a reasonable period? Start a procedure at the subdistrict court in The Hague (competent for Delft), with a claim for repayment plus 9% statutory interest and court costs.
Example: A female student tenant in Delft-West recently won her case at the subdistrict court; the judge ordered the landlord to repay €220 because no proof of key copying or replacement was provided. Tip: At departure, make a detailed key handover protocol with timestamp photos and witness statements.
