Sources and Authority
• Consent by Acceptance of Beneﬁts. Civil Code section 1589.
•Because acceptance must be communicated, “[s]ilence in the face of an offer is
not an acceptance, unless there is a relationship between the parties or a
previous course of dealing pursuant to which silence would be understood as
acceptance.” (Southern California Acoustics Co., Inc. v. C. V. Holder, Inc.
(1969) 71 Cal.2d 719, 722 [79 Cal.Rptr. 319, 456 P.2d 975].)
• Acceptance may also be inferred from inaction where one has a duty to act, and
from retention of the offered beneﬁt. (Golden Eagle Insurance Co. v. Foremost
Insurance Co. (1993) 20 Cal.App.4th 1372, 1386 [25 Cal.Rptr.2d 242].)
