In an effort to provide a better understanding for what undue influence expert psychologists look for when forming opinions about whether undue influence occurred in the execution of a will, trust, beneficiary designation, or other contractual document, I am highlighting the statutes, case law, and jury instructions specific to all 50 states. Each will be in its own blog post. Fifth up, California.

Rice v. Clark (2002) 28 Cal.4th 89, 96:

Undue influence is “pressure brought to bear directly on the testamentary act, sufficient to overcome the testator’s free will, amounting in effect to coercion destroying the testator’s free agency.”

California Welfare and Institutions Code § 15610.70:

Undue influence is “excessive persuasion that causes another person to act or refrain from acting by overcoming that person’s free will and results in inequity.” In determining whether a result was produced by undue influence, all of the following shall be considered:

(1) The vulnerability of the victim. Evidence of vulnerability may include, but is not limited to, incapacity, illness, disability, injury, age, education, impaired cognitive function, emotional distress, isolation, or dependency, and whether the influencer knew or should have known of the alleged victim’s vulnerability.

(2) The influencer’s apparent authority. Evidence of apparent authority may include, but is not limited to, status as a fiduciary, family member, care provider, health care professional, legal professional, spiritual adviser, expert, or other qualification.

(3) The actions or tactics used by the influencer. Evidence of actions or tactics used may include, but is not limited to, all of the following:

(A) Controlling necessaries of life, medication, the victim’s interactions with others, access to information, or sleep.

(B) Use of affection, intimidation, or coercion.

(C) Initiation of changes in personal or property rights, use of haste or secrecy in effecting those changes, effecting changes at inappropriate times and places, and claims of expertise in effecting changes.

(4) The equity of the result. Evidence of the equity of the result may include, but is not limited to, the economic consequences to the victim, any divergence from the victim’s prior intent or course of conduct or dealing, the relationship of the value conveyed to the value of any services or consideration received, or the appropriateness of the change in light of the length and nature of the relationship.

Evidence of an inequitable result, without more, is not sufficient to prove undue influence.

California Probate Code § 21380: Presumption of undue influence

(a) A provision of an instrument making a donative transfer to any of the following persons is presumed to be the product of fraud or undue influence:

(1) The person who drafted the instrument.

(2) A person who transcribed the instrument or caused it to be transcribed and who was in a fiduciary relationship with the transferor when the instrument was transcribed.

(3) A care custodian of a transferor who is a dependent adult, but only if the instrument was executed during the period in which the care custodian provided services to the transferor, or within 90 days before or after that period.

(4) A care custodian who commenced a marriage, cohabitation, or domestic partnership with a transferor who is a dependent adult while providing services to that dependent adult, or within 90 days after those services were last provided to the dependent adult, if the donative transfer occurred, or the instrument was executed, less than six months after the marriage, cohabitation, or domestic partnership commenced.

(5) A person who is related by blood or affinity, within the third degree, to any person described in paragraphs (1) to (3), inclusive.

(6) A cohabitant or employee of any person described in paragraphs (1) to (3), inclusive.

(7) A partner, shareholder, or employee of a law firm in which a person described in paragraph (1) or (2) has an ownership interest.

(b) The presumption created by this section is a presumption affecting the burden of proof. The presumption may be rebutted by proving, by clear and convincing evidence, that the donative transfer was not the product of fraud or undue influence.

(c) Notwithstanding subdivision (b), with respect to a donative transfer to the person who drafted the donative instrument, or to a person who is related to, or associated with, the drafter as described in paragraph (5), (6), or (7) of subdivision (a), the presumption created by this section is conclusive.

(d) If a beneficiary is unsuccessful in rebutting the presumption, the beneficiary shall bear all costs of the proceeding, including reasonable attorney’s fees.

California Probate Code § 21382 and § 21385: Presumption of undue influence

These codes exempt certain family members and spouses from the presumption of undue influence in § 21380.

Keithley v. Civil Service Bd. Of the City of Oakland (1970) 11 Cal.App3d 443, 451:

“[D]irect evidence of undue influence is rarely obtainable and, thus the court is normally relegated to determination by inference from the totality of facts and circumstances. Indeed, there are no fixed definitions or inflexible formulas. Rather, we are concerned with whether from the entire context it appears that one’s will was overborne and he was induced to do or forbear to do an act which he would not do, or would do, if left to act freely.”

Davies v. Krasn (1975) 14 Cal. 3d 502, 510, 121 Cal. Rptr. 705: Confidential Relationship

“A confidential relation exists between two persons when one has gained the confidence of the other and purports to act or advise with the other’s interest in mind. A confidential relation may exist although there is no fiduciary relation; it is particularly likely to exist where there is a family relationship or one of friendship or such a relation of confidence as that which arises between physician and patient or priest and penitent.”

O’Neil v. Spillane (1975) 45 Cal.App3d 147, 153:

“It is, of course, well settled that while the mere fact that a relationship is friendly and intimate does not necessarily amount to a confidential relationship, such relationship may be said to exist whenever trust and confidence is reposed by one person in the integrity and fidelity of another. It is likewise frequently emphasized that the existence of a confidential relationship presents a question of fact which, of necessity, may be determined only on a case by case basis.”
