Question juridique clé
Whether future heirship of the seller's descendant constitutes a protectable interest for access to the purchase contract and purchase price.
Solution extraite
No. A merely prospective heirship while the mother is still alive does not yet create a sufficient interest in the purchase contract or price.
Motifs extraits
Before the testator's death there are no heirs, and any possible inheritance prejudice can only be asserted at that time; otherwise the privacy of contractual parties would be unduly impaired.
