Note 309 — Chapter XVI · TITLES.
Reading edition
The terms unilateral and bilateral possess another signification distinct from that which is attributed to them in the text. In the sense there adopted all agreements are bilateral, but there is another sense in which some of them are bilateral and others unilateral. An agreement is bilateral, in this latter signification, if there is something to be done by each party to it, while it is unilateral if one party is purely passive and free from legal obligation, all the activity and obligation being on the other side. An agreement to lend money is bilateral, while an agreement to give money is unilateral.
