If the renter wishes to extend the car rental and it involves renting for more than one day, they must notify the lessor in writing at least twenty-four (24) hours before the rental expires to receive the relevant written approval. The written notification must be made via email. Failure to do so entails civil and criminal liability for illegal use and possession of the car. In the event of extending the rental, the renter is bound by the terms and agreements of both the original rental agreement and the extension agreement, whether it concerns the same car or a replacement.
