Takeaways:
- California’s definition for testamentary incapacity is found in Probate Code § 6100.5. A person lacks testamentary capacity if they can’t understand the act of making a will, what they own, or their relationships with close family, or if a mental disorder produces delusions that distort the plan.
- Capacity is judged at the exact moment the will was signed, not weeks before or after, which is why timing and contemporaneous medical notes carry so much weight.
- Lack of capacity and undue influence are different legal grounds, but they often appear together because diminished mental capacity makes a person easier to manipulate or unduly influence.
- California law presumes the will-maker, or testator, had capacity, so the burden falls on the person contesting the will to prove otherwise, and only an interested person such as a beneficiary, prior beneficiary, or heir has standing to file.
When someone you love passes away, reading their will should bring a sense of closure. Sometimes it brings questions instead. Maybe the document leaves out close family, rewards a recent caregiver, or simply doesn’t sound like the person you knew. If your loved one was struggling with memory, confusion, or serious illness near the end of their life, you may be asking whether they truly understood what they were signing. That question sits at the heart of a legal concept called lack of testamentary capacity. Our experienced San Diego wills lawyers can help.
What Is Testamentary Capacity?
Testamentary capacity is the level of mental soundness a person must have to create a valid will. California law sets a relatively low bar, and it assumes most adults meet it. Under California Probate Code § 6100, an individual 18 or more years of age who is of sound mind may make a will.
“Sound mind” doesn’t mean perfect memory or flawless judgment. A person can be elderly, forgetful, physically frail, or even diagnosed with a cognitive condition and still have the capacity to make a will. What matters is their mental state at the specific moment they signed the document. Capacity can also fluctuate. Someone with dementia may be confused one day and clear the next, which is why the timing of the signing is so important.
The California Standard For Testamentary Capacity
California Probate Code § 6100.5 explains when a person is not mentally competent to make a will. Under that standard, a person may lack capacity if they are unable to understand any one of the following:
– The nature of the testamentary act, meaning they understand they’re making a will that distributes their property after death.
– The nature and situation of their property, meaning they have a general sense of what they own.
– The individual’s relations to living descendants, spouse, and parents, as well as anyone whose interests are affected by the will.
The statute also addresses a separate situation. A person may lack capacity if they suffer from a mental health disorder with symptoms including delusions or hallucinations, which result in the individual devising property in a way that, except for the existence of the delusions or hallucinations, they would not have done. For example, a false and fixed belief that a devoted daughter was stealing from them might lead someone to disinherit her without any basis in reality.

Signs And Evidence Of A Lack Of Capacity
Proving what was happening in someone’s mind on a particular day is challenging, but it’s far from impossible. Capacity is reconstructed through evidence, and several sources often tell the story.
Medical records frequently carry significant weight. Relevant records might include a diagnosis of advanced dementia or Alzheimer’s, along with notes describing confusion or disorientation, and information about medications known to affect cognition. The individuals who were present also matter. Witnesses such as caregivers, friends, the drafting attorney, and the will’s witnesses may describe how the person was acting around the time the will was signed.
Other warning signs include a will created or changed suddenly during a period of serious decline, a dramatic departure from a long-standing estate plan, or a new document that benefits someone who recently became involved in the person’s life. None of these facts alone proves a lack of capacity, but together they can paint a compelling picture.
Gathering and presenting this kind of evidence takes care and preparation. Our team at Weiner Law can review the records and circumstances with you. Call 866-273-8652 to discuss your concerns.
How Lack Of Capacity Differs From Undue Influence
Lack of testamentary capacity and undue influence are different legal grounds, though they often appear in the same case. Lack of capacity focuses on the will-maker’s own mind. Undue influence focuses on the conduct of another person who pressured or manipulated the will-maker into changing their plan. Under California Probate Code § 6104, the execution or revocation of a will is ineffective to the extent it was procured by duress, menace, fraud, or undue influence.
These two claims overlap because diminished mental capacity can make a person easier to manipulate. Someone confused and dependent on a caregiver is far more vulnerable to pressure than someone sharp and independent. For that reason, our team often examines both questions together when reviewing a contested will.
Contesting A Will And The Burden Of Proof
Not just anyone can challenge a will. Generally, you need standing, which means you’re an interested person, such as a beneficiary named in the will, a beneficiary under a previous will, or an heir who would inherit if the will were set aside. There are also strict deadlines, so it’s important to act without unnecessary delay.
California law presumes that a person who made a will had the capacity to do so. That means the burden falls on the person contesting the will to prove a lack of capacity. Courts look closely at the testator’s condition at the time of signing, not weeks before or after. This is a meaningful hurdle, and it’s the reason evidence and preparation make such a difference. A will contest involves filing in the probate court, gathering medical and witness evidence, and often litigation that can stretch from many months to a few years, depending on the complexity.
