Irving Duke created a "holographic" (i.e., hand written) will under which his wife was to receive all of his property. However, the will dictated that if Duke and his wife died at the same time, then his property was to be divided amongst various charities.
What Duke did not contemplate in his will is the possibility that his spouse would pass away before he did, which is exactly what happened.
As Duke had never redrafted his will after his wife passed away, the trial and appellate courts declared that his property should go to his relatives under the laws of intestacy. However, the California Supreme Court ruled that an unambiguous will can be reformed by the court if it can be established by clear and convincing evidence that a mistake was made in expressing the testator's intent at the time the will was drafted.
The Wills, Trusts & Estates Prof Blog reported on this case in "Unambiguous Will May Be Reformed Because Of Mistake."
This means that if the charities can establish that Duke clearly meant for his property to go to them in the event his wife was not able to inherit it, then the court can effectively rewrite the will to make that clear and the charities would inherit Duke's property.
It is difficult to determine what a deceased person intended to do.
While it might seem clear that Duke intended his property to either go to his wife or to the charities, it could also be the case that he intended to rewrite his will if his wife did pass away before him.
Consequently, this is the reason courts have generally been unwilling to rewrite potentially mistaken wills. It now appears probate courts in California will need to determine what a deceased person intended when the will is silent on an issue.
