00:00A unilateral undertaking is an act by which a person intends to create an obligation for themselves.
00:05without requiring prior agreement with another person for its formation.
00:09The theoretical difficulty arises from the fact that an obligation normally establishes a relationship between a creditor and a debtor, whereas
00:15The initial commitment stems from a single will.
00:17The recognition of this concept nevertheless helps to explain certain obligations that arise from a promise made by a person.
00:23A person may first feel morally obligated, and then promise to perform that duty.
00:28Article 1100, paragraph 2, helps to understand how a promise to fulfill a duty of conscience can produce
00:34legal effects.
00:36It is therefore necessary to distinguish between a unilateral undertaking, which concerns the source of the obligation, and a contract, which presupposes an agreement.
00:42of will.
