In re Estate of Duke, 61 Cal. 4th 871, 190 Cal. Rptr. 3d 295, 352 P.3d 863 (Cal. 2015)
In re Estate of Duke is a landmark California Supreme Court decision that reshaped the law of wills by recognizing a judicial power to reform a will that, as written, fails to reflect the testator's actual intent due to a mistake. Prior California doctrine had generally been understood to prohibit reformation of an unambiguous will, even when compelling extrinsic evidence showed a drafting error or other mistake.
May a California court reform an unambiguous will to conform to the testator's actual intent based on extrinsic evidence showing that a mistake of fact or law affected the expressed terms of the will at execution?
A California court may reform an unambiguous will to conform to the testator's actual intent if the proponent establishes by clear and convincing evidence: (1) that a mistake of expression or inducement—of fact or law—affected specific terms of the will at the time of drafting and execution, and (2) the testator's actual, specific testamentary intent at that time. Extrinsic evidence is admissible to prove both the existence of the mistake and the testator's intended terms, even if such evidence contradicts the plain meaning of the written words. Reformation must implement the testator's true intent without contravening applicable statutes or public policy, and cannot be used to create a new testamentary scheme unmoored from that proven intent.
Yes. The California Supreme Court held that courts may reform a will upon clear and convincing evidence of a drafting or inducement mistake and of the testator's actual intent at execution, thereby abrogating the categorical bar on reformation of unambiguous wills. The Court reversed and remanded for the probate court to determine, under the correct standard, whether the charities could meet their evidentiary burden.
Duke modernizes California wills law by recognizing an equitable reformation remedy that prioritizes proven testamentary intent while safeguarding against fraud through a heightened evidentiary threshold. For students, it is pivotal on three fronts: (1) it expands the admissibility and use of extrinsic evidence beyond ambiguity resolution to mistake correction; (2) it harmonizes wills doctrine with parallel reformation doctrines in contracts and trusts; and (3) it supplies a clear, two-pronged, clear-and-convincing standard that frames future probate litigation. Duke is now the controlling California authority on when courts may reform testamentary instruments to avoid unintended intestacy or misdirected bequests.
