Frequently asked questions

Who inherits if a will is found invalid in California?

The estate passes under California's intestate succession laws unless a prior valid will exists and is admitted to probate. Intestate succession sends property to the decedent's closest relatives in the order California law sets. When an earlier will is offered, the court first decides whether the later will is entitled to probate, and the result turns on which other documents exist and are valid.

What are the grounds for contesting a will in California?

Recognized grounds include lack of testamentary capacity, undue influence, fraud, duress, mistake, revocation, forgery and improper execution. Capacity is measured under Probate Code section 6100.5 at the time the will was made, and undue influence takes its meaning from Probate Code section 86. Gifts to the drafter and certain other people may be presumed the product of fraud or undue influence under Probate Code section 21380. The list is not exhaustive.

How long do I have to contest a will in California?

The time depends on whether the will has been admitted to probate. Before admission, an objection to probate may be filed under Probate Code section 8250, and those served then have 30 days after service to respond. After admission, Probate Code section 8270 generally allows an interested person 120 days to petition to revoke probate; a person who was a minor or incompetent without a guardian or conservator at admission may petition any time before final distribution.

Will a no-contest clause prevent me from challenging a will?

Not necessarily. Under Probate Code section 21311(a), a no-contest clause can be enforced only against a direct contest brought without probable cause and, if the clause expressly says so, certain property-ownership challenges and creditor's claims. A direct contest brought with probable cause, judged by the facts known when it is filed, does not trigger the clause.

What is testamentary capacity under California law?

It is the mental ability to make a will at the moment the will is made, measured by the elements in Probate Code section 6100.5. Those elements include understanding the act of making a will, the nature and situation of one's property, and one's relationships to close family and others affected. A diagnosis such as dementia does not by itself make a will invalid.

Can a caregiver or drafter inherit under a California will?

Sometimes, but certain gifts face a legal presumption. Probate Code section 21380(a) presumes fraud or undue influence for gifts to the drafter, to a fiduciary who transcribed the will, and to a care custodian of a dependent adult when the will was signed during services or within 90 days before or after. The beneficiary may rebut it by clear and convincing evidence, except that it is conclusive for the drafter and people associated with the drafter. Gifts to other caregivers and relatives are not presumed invalid under this section.
