To be valid under California Probate Code Section 6110, a will must be in writing, signed by the person making it, and witnessed by at least two people who are present together when they watch the testator sign or hear the testator acknowledge the signature or the document as their will.1California Legislative Information. California Probate Code 6110 – Execution of Wills A will that misses any of these steps risks being rejected in probate, which sends the estate through California’s intestacy rules instead of the testator’s chosen distribution. Small missteps at signing cause most of the fights.
The Three Requirements Under Section 6110
The statute sets out three elements, and all three must be satisfied.
First, the will has to be in writing. Oral wills are not recognized. Second, the testator must sign the document personally, or have another person sign for them under the conditions described below. Third, two witnesses must sign during the testator’s lifetime, having both been present at the same time when the testator either signed the will or acknowledged their signature or the will itself.1California Legislative Information. California Probate Code 6110 – Execution of Wills The witnesses also must understand that the document they are signing is the testator’s will.
Section 6110 does not require the testator to declare the document a will out loud, and it does not require notarization. California has no self-proving affidavit procedure. Many other states allow the testator and witnesses to sign a notarized affidavit at execution so the will can later be admitted without live witness testimony. California offers no such shortcut, so your witnesses may be called to confirm what they saw in probate court.
The Testator’s Signature
The statute does not prescribe a form for the signature. A full legal name, initials, or a mark can all work, as long as the testator intends the writing to be their signature.1California Legislative Information. California Probate Code 6110 – Execution of Wills
When the testator physically cannot sign, another person may sign for them, but two conditions have to be met together: the substitute signer must act in the testator’s presence, and the testator must direct them to sign.1California Legislative Information. California Probate Code 6110 – Execution of Wills A relative who quietly signs on behalf of a hospitalized family member, without being asked to, fails this test.
Mental capacity sits behind the signature. Under Section 6100.5, a testator lacks capacity if they cannot understand what making a will does, cannot recall the general nature and extent of their property, or cannot remember their relationship to the spouse, children, parents, and others affected by the will. Capacity is also absent when a mental health condition causes delusions or hallucinations that directly change how the testator leaves property.2California Legislative Information. California Probate Code – General Provisions The bar is lower than many people assume. Someone in the early stages of dementia may still sign validly during a lucid interval; what matters is the moment of signing.
The Two-Witness Rule in Practice
The simultaneous-presence requirement is where most wills go wrong. Both witnesses need to be in the room together at the moment they observe the testator sign the will or hear the testator acknowledge it. One witness signing in the morning and the second signing that afternoon creates a defect, even if both watched the testator sign.1California Legislative Information. California Probate Code 6110 – Execution of Wills
The witnesses also must know they are witnessing a will. Handing someone a stack of paperwork and asking them to sign the bottom without telling them what it is does not satisfy the statute. They do not need to read the contents, but they do need to understand the nature of the document.
Any person generally competent to be a witness qualifies.3California Legislative Information. California Probate Code 6112 – Interested Witnesses There is no age minimum in the statute beyond general witness competency, and the witnesses do not need to be California residents.
When a Witness Also Inherits
Using a beneficiary as a witness does not automatically invalidate the will. Section 6112 permits it. But the arrangement triggers a legal problem for that witness.3California Legislative Information. California Probate Code 6112 – Interested Witnesses
Unless at least two other disinterested witnesses also signed, the law presumes the interested witness obtained their gift through duress, menace, fraud, or undue influence. That witness then has to prove to the court that the gift was legitimate. If they cannot overcome the presumption, they lose the gift under the will, though they can still receive whatever share they would have taken under intestacy had the will never existed.3California Legislative Information. California Probate Code 6112 – Interested Witnesses
The presumption does not apply when the witness receives property solely in a fiduciary capacity, such as serving as trustee.3California Legislative Information. California Probate Code 6112 – Interested Witnesses The cleanest approach is still the obvious one: pick two witnesses with no stake in your estate.
The Harmless Error Safety Valve
California added a rescue provision in 2008 for wills that fall short on execution. Under Section 6110(c)(2), a court can treat a defective will as properly executed if the person offering it for probate proves by clear and convincing evidence that the testator intended the document to be their will when they signed it.1California Legislative Information. California Probate Code 6110 – Execution of Wills
Clear and convincing evidence is a high standard, well above the usual civil “more likely than not” test. The rule tends to rescue wills with narrow defects, such as one witness signing slightly outside the presence of the other, or a witness who did not appreciate what the document was. It is not permission to skip formalities. Litigation under the harmless error rule is expensive, uncertain, and avoidable by following the statute at signing.
Handwritten Wills Are a Separate Track
Section 6110 governs formal, witnessed wills. It does not govern holographic wills. Under Section 6111, a will that fails Section 6110’s formalities is still valid if the signature and material provisions are in the testator’s own handwriting, and no witnesses are needed. Material provisions are the parts that describe who gets what and how the estate should be handled. A testator can start from a printed form and complete the handwritten portions, and statements of testamentary intent may appear in either the printed or handwritten text.4California Legislative Information. California Probate Code 6111 – Holographic Wills
Holographic wills carry a real risk when undated. If an undated holographic will conflicts with another will, courts will treat the holographic will as invalid to the extent of the inconsistency unless the proponent can prove it came later. An undated holographic will is also vulnerable if there is evidence the testator lacked capacity during any period when it might have been written.4California Legislative Information. California Probate Code 6111 – Holographic Wills Date it.
What Happens If the Will Fails
When a will is rejected in probate, California’s intestacy statutes take over. Community property and quasi-community property pass entirely to the surviving spouse, since the spouse already owns their own half.5California Legislative Information. California Probate Code 6401 – Intestate Share of Surviving Spouse Separate property is split between the spouse and the decedent’s children, parents, or siblings on a formula that depends on who survives, and whatever does not go to the spouse flows down a statutory priority list of relatives.6California Legislative Information. California Probate Code 6402 – Intestate Estate Distribution
Stepchildren who were never legally adopted do not inherit under these rules. Neither do unmarried partners, close friends, or charities. The only way to leave property to anyone outside the statutory hierarchy is through a valid will or another estate planning tool, which is exactly why getting Section 6110 right at signing matters.
