The defendant is the owner of a house. Because of renovation works he wanted to have performed in his house, he contacted the first plaintiff to carry out the plans and do the follow-up. The first fee sent by the first plaintiff for its work was paid by the defendant. The first plaintiff continued the project of the defendant, which included the establishment of a detailed measurement of the renovation and the interior design. The works were conducted on the basis of a measurement made by different contractors, including a measurement made by the second plaintiff.
For the fulfilment of her work, the second plaintiff handed out 3 invoices, of which the 2 first ones were paid. The last invoice, which was handed out when the work was completed, was not paid. After a reminder by the second plaintiff, the defendant protested the invoice on grounds that the amount was too high, claiming that he already paid too much. A few days later the defendant said he wanted to terminate the contract because he was dissatisfied with the follow-up by the second plaintiff, referring to unfinished or poorly executed work. The second plaintiff contested these allegations and sent its final bill to the defendant. The defendant contested the final bill and did not proceed to payment.
Consequently, the second plaintiff initiated legal proceedings against the defendant to pay the final bill plus damages and arrears.
Two months later, the second plaintiff summoned the defendant to pay its due amount increased with damages and arrears. Several months later, the defendant filed a counterclaim for the repayment of what he paid too much and to receive a credit note of this amount.
