Explanation of Article 162
This article clarifies that the provisions of the contract apply to unilateral acts, except for matters related to the necessity of having two matching wills to create an obligation, unless the statutory texts provide otherwise. This means that most of the rules related to the contract also apply to obligations arising from a single will.
