Article 1387. All contracts by virtue of which the debtor alienates property by gratuitous title are presumed to have been entered into in fraud of creditors, when the donor did not reserve sufficient property to pay all debts contracted before the donation.
Alienations by onerous title are also presumed fraudulent when made by persons against whom some judgment has been rendered in any instance or some writ of attachment has been issued. The decision or attachment need not refer to the property alienated, and need not have been obtained by the party seeking rescission.
