What are the three elements of undue influence?
California’s statute lists four considerations, not three: the vulnerability of the victim, the influencer’s apparent authority, the actions or tactics used, and the equity of the result (Welfare and Institutions Code section 15610.70). The “three elements” framing comes from older case law and other states.
| Factor | What it can look like |
|---|---|
| Vulnerability of the victim | Illness, dementia, grief, isolation, dependence on others for care, or reliance on medication. |
| Apparent authority of the influencer | A caregiver, a child with power of attorney, a new spouse, a financial adviser or anyone the victim trusts and relies on. |
| Actions or tactics used | Controlling medication, visits, phone calls or mail; rushing changes through; keeping them secret from the family. |
| Equity of the result | A gift far out of line with a long-standing plan, or with how the person treated their family for decades. |
The statute names specific tactics: controlling the victim’s necessaries of life, medication, interactions with others or access to information, and using haste or secrecy in making changes.
How hard is it to prove undue influence in a will?
Hard without evidence beyond the result. The statute says evidence of an inequitable result, without more, is not sufficient (Welfare and Institutions Code section 15610.70). Strong cases connect the unfair result to vulnerability, a person in a position of trust, and the tactics used.
Warning signs families notice
- A new caregiver, companion or friend who quickly becomes indispensable.
- Sudden changes to a trust, will, deed, beneficiary designation or power of attorney.
- Family members cut off from visits or calls, or told the parent “does not want to see” them.
- A new attorney the family has never heard of, often chosen by the person who benefits.
- Large withdrawals, new joint accounts, or checks that do not fit the person’s habits.
What is the burden of proof for undue influence in California?
Usually the person claiming undue influence must prove it. But Probate Code section 21380 presumes fraud or undue influence when a gift goes to certain people, such as the person who drafted the document or a care custodian of a dependent adult, and that person must then disprove it by clear and convincing evidence.
Who the presumption covers
- The person who drafted the instrument.
- A person in a fiduciary relationship with the transferor who transcribed the instrument or had it transcribed.
- A care custodian of a dependent adult, if the instrument was signed during the period of care or within 90 days before or after it.
- A care custodian who married or began living with the dependent adult during the care, or within 90 days after it ended, if the instrument was signed less than six months after the relationship began.
- Relatives, cohabitants and employees of the people above, and partners, shareholders and employees of a drafting attorney’s law firm.
For the drafter, and the drafter’s relatives and law firm, the presumption is conclusive: it cannot be rebutted at all. A beneficiary who fails to rebut the presumption bears all costs of the proceeding, including reasonable attorney’s fees (Probate Code section 21380).
There are exceptions in Probate Code section 21382, including gifts to relatives within the fourth degree and some gifts of $5,000 or less. The presumption also does not apply if an independent attorney counseled the transferor alone and signed a certificate of independent review (Probate Code section 21384).
What constitutes financial elder abuse in California?
Taking, hiding, appropriating, obtaining or keeping the property of a person 65 or older for a wrongful use, with intent to defraud, or by undue influence, or helping someone else do so (Welfare and Institutions Code section 15610.30). It includes depriving an elder of property through a gift, a trust or a will.
An “elder” is any California resident 65 or older (Welfare and Institutions Code section 15610.27). Conduct is a wrongful use if, among other things, the person knew or should have known it was likely to be harmful to the elder. That reaches changes to an estate plan, not only stolen cash.
What proof is needed for elder abuse?
Financial elder abuse is proven by a preponderance of the evidence, which means more likely than not, and that alone requires an award of attorney’s fees and costs (Welfare and Institutions Code section 15657.5). Proving recklessness, oppression, fraud or malice by clear and convincing evidence opens further remedies.
The remedies
- Attorney’s fees and costs, mandatory once financial abuse is proven (Welfare and Institutions Code section 15657.5).
- Compensatory damages for what was taken.
- Damages that survive the victim’s death, including pain and suffering, if recklessness, oppression, fraud or malice is proven by clear and convincing evidence.
- Punitive damages where the standards in Civil Code section 3294 are met.
- Twice the value of the property recovered, where property was taken in bad faith, by undue influence in bad faith, or through elder financial abuse (Probate Code section 859).
Evidence that matters
- Medical and care facility records around the dates of the changes.
- Bank, brokerage and credit card statements.
- The drafting attorney’s file and who arranged and paid for the appointments.
- Texts, emails and voicemails, and the names of people who visited or were turned away.
What do you do when someone takes advantage of the elderly?
Preserve the evidence, protect what is left, and get legal advice quickly. If the person is still living and at risk, report it to your county’s Adult Protective Services. If they have died, the trust contest deadline may already be running.
- Preserve documents. Bank statements, the estate plan and every version of it, emails and texts.
- Get the medical records. They are often the most important evidence of vulnerability.
- Protect remaining assets. Courts can act quickly when property is at risk.
- Watch the deadline. If a trustee’s notice has been served, a contest generally must be filed within 120 days. See contesting a trust.
