Received a defective commissioned construction?
If a commissioned construction is defective, you as the client can file a guarantee claim against the contractor.
Work is deemed defective if, on acceptance, it does not conform to the contractual stipulations. In this case, you have the option of canceling the contract. The reporting of the defect and the assertion of the cancelation are not required to take a particular form.
However, for evidential reasons, we recommend that you produce a written statement and send it by registered post.
