La riserva della proprietà nella vendita immobiliare con particolare riguardo ai rapporti tra coniugi e tra coeredi

[Autom. eng. transl.] The essay examines the question concerning the eligibility of the property reserve in the sale of real estate. Reconstructed in terms of real expectation the legal situation that arises from the contract before the translational effect, verifies its compatibility with the principle of typicality of real rights. The positive solution is based on regulatory indexes that allow the buyer to oppose his right to purchase the property from the seller's third creditors and his assignees. The deferral of the translational effect with respect to the time of the conclusion of the agreement poses the problem of the relevance of contingencies such as the marriage and the death of the buyer. These cases are taken into consideration from the point of view of the communion regime between spouses and joint heirs, in order to establish respectively the exclusive or common belonging of the purchased good and the solidarity or partial nature of the obligation to pay the price.
