According to Article 1648 Civil Code, an action based on destructive defects must be initiated within a reasonable time against the seller. In this case, a building was sold to the consumer with hidden defects. In order to assess whether an action is brought to Court within a reasonable time, the relevant circumstances of the case must be taken into account. The reasonable period starts running from the moment that the defect becomes apparent or in the case that the defect becomes apparent after an extended use of the good from the moment that the buyer is aware or should have been aware of the defect. The consumer brought an action before a Court against the seller for infiltration of water in a terrace on the first floor of the building, more than one year after the defect became apparent to him (as a result of an expert report).
