Which statement BEST describes the doctrine of WAIVER in California insurance law?

a.Waiver is the voluntary and INTENTIONAL relinquishment of a known right; once an insurer waives a defense (e.g., by accepting a late premium with full knowledge of the lateness), it generally cannot later assert that defense to deny coverage
b.Waiver requires a written, notarized declaration in every case
c.Waiver is the same as estoppel and the two are interchangeable in California courts
d.Waiver may be asserted only by the insured, never by the insurer

Explanation

WAIVER is the voluntary and intentional relinquishment of a known right. In California insurance law (see e.g., California Insurance Code §650 and case law), an insurer that knows of a policy defense (such as late payment, breach of a condition, or a misrepresentation) yet acts inconsistently with reliance on that defense — for example, accepting a late premium without reservation, or continuing to process a claim — may be held to have WAIVED the defense and cannot later assert it to deny coverage. ESTOPPEL is related but distinct: it focuses on the OTHER party's detrimental reliance on the first party's conduct, regardless of intent. Option B fabricates a notarization requirement. Option C overstates the equivalence — though both reach a similar result, the elements differ (intent vs. reliance). Option D is wrong; either party may waive a right.

Law Reference: California Insurance Code §650 (abandonment / waiver of subrogation principles)
