By the Award granted on the 18th October 2012 in proceedings number 247/2012, the Court of Second Instance has stated that, notwithstanding the circumstance that the promissory sale and purchase contract is, in principle, of contractual nature, and, being so, de per si, does not transfer the ownership neither the possession (“posse”) over the goods, in case that, following the execution of the promissory contract,
1. the promissory purchaser settles the price in full,
2. the
traditio of the goods occurs and
3. the promissory purchaser starts acting as the owner, the position of the promissory purchaser fulfills the legal requisites of the possession, as defined in Section 1175.º of the Civil Code.
