Revocation by Subsequent Instrument

Cal. Prob. Code § 6120(a)

The rule

A will is revoked by a subsequent will that revokes the prior will either expressly or by inconsistency. Where the subsequent will disposes of only part of the estate, the prior will is revoked only to the extent inconsistent.

In plain English

A will can be revoked if a new will is created that either explicitly states it revokes the previous will or is inconsistent with it. If the new will only deals with part of the estate, the old will remains valid for the portions not addressed by the new will.

Worked example

Alice creates a will leaving her entire estate to her sister. Later, she drafts a new will that leaves her house to her brother but does not mention the rest of her estate. In this case, the first will is revoked only as to the house, while the rest of the estate still goes to her sister.

Memory hook

New will, new rules—revocation by inconsistency!

The trap

Exams may present scenarios where students overlook that only part of a will can be revoked, leading to confusion about the remaining provisions. Watch for language that suggests partial revocation.

How examiners test it

Questions often involve multiple wills and test the candidate's ability to identify which parts of the estate are affected by subsequent instruments. Look for inconsistencies or explicit revocations in the fact patterns.
