Undue Influence in California

Undue Influence in California (also known as UI) can happen when the senior is reasonably capable but is at risk due to various other factors. These can include cognitive decline, dependence, and/or isolation. 

Although it is sometimes perpetrated by a stranger or a new person in the life of the victim, it is often done by a loved one. Undue influence can take many forms: from isolating the victim by preventing them from speaking freely to trusted loved ones to taking control of medical decisions to putting pressure on the victim about their financial choices. 

The definition of undue influence in California received a makeover on January 1, 2014, with California Probate Code section 86 and California Welfare and Institutions Code section 15610.70 going into effect. The California Legislature felt a need to provide a clear definition of undue influence in California probate courts. Increasingly, court officials and attorneys are depending on neuropsychologists like Dr. Stacey Wood to help make assessments, testify in court, and assist in investigations.

Why choose Dr. Wood for undue influence cases?

Proving undue influence California is a difficult task for attorneys, especially where a particular family member is the apparent authority figure. Courts are inclined to believe that individuals have sufficient mental capacity to execute their own wishes and thus, the majority of UI cases are disregarded or dismissed due to lack of evidence.

Difficult cases are, nonetheless, not impossible. In 2014, clarifications of the Undue Impact statute in Orange County and throughout California equipped petitioners with a significantly boosted capacity to persuasively argue their positions.

Curriculum Vitae

My scholarly interests are in the areas of neuropsychology and decision-making from a lifespan development perspective. I am interested in how changes in the brain, emotion, and motivation interact across the lifespan to influence how we make decisions. I am especially interested in taking theoretical work and applying it to everyday types of decisions. One such application is in the area of assessing decision-making capacity for the courts. An understanding of cognitive mechanisms that may underlie specific types of legal decisions (i.e. testamentary, financial) can help us to design better tools and be more effective as witnesses.

Undue Influence in California: Extended Information

Generally, UI refers to a forceful dynamic between two individuals where one exerts “excessive persuasion” upon the other. This involves pressure on an individual that causes that person to act according to the wishes and for the benefit of the influencer, often in ways that oppose his or her own personal interests. This pressure can take place by way of harassment, threats, seclusion, or threats of isolation.

Frequently the influencer places him/herself between the individual and friends/loved ones. This makes the victim easier to coerce. Having the consultation of a reputable psychologist with “fraud in the family” experience can shed light on the matter.

Undue Influence California Law

Unfortunately, the impact of undue influence California usually expands beyond that of financial loss. The resultant stress and anxiety can trigger strong negative feelings like rage and despair. They can even take a physical and psychological toll on someone who was previously a strong and mentally healthy person.

The good news is, the 2014 clarifications of the Undue Influence law in Orange County and throughout California has considerably improved a petitioner’s capacity to build a winning case. Retaining a forensic psychologist with undue influence and capacity experience can further improve the odds of presenting a winning case.

850 Petition in California

A typical 850 Petition in California is used to transfer real property into a revocable trust after the death of a trust creator (called the “Settler”) where title to such property was not properly titled in the name of the trust before death (Davidson, Keith A. November 23, 2010).

One of the most commonly cited cases in 850 Petitions is the Estate of Heggstad.


California Probate Code, Section 15800

Another important Undue Influence California code is Probate Code, Section 15800, which states:

Except to the extent that the trust instrument otherwise provides or where the joint action of the settlor and all beneficiaries is required, during the time that a trust is revocable and the person holding the power to revoke the trust is competent:

(a) The person holding the power to revoke, and not the beneficiary, has the rights afforded beneficiaries under this division.

(b) The duties of the trustee are owed to the person holding the power to revoke.

California Probate Code Section 86

California Probate Code Section 86 can be found in Division 1, Part 2.

“Undue influence” has the same meaning as defined in Section 15610.70 of the Welfare and Institutions Code. It is the intent of the Legislature that this section supplement the common law meaning of undue influence without superseding or interfering with the operation of that law.

(Added by Stats. 2013, Ch. 668, Sec. 1. Effective January 1, 2014.)

A qualified, local psychologist can further explain how this can be used to benefit your clients.


California Welfare and Institutions Code Section 15610.70

California Welfare and Institutions Code Section 15610.70 was enacted by the California Legislature in 2013 and the text serves as the definition within the state to determine whether someone was unduly influenced.

(a) “Undue influence” means 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.

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

(Added by Stats. 2013, Ch. 668, Sec. 3. Effective January 1, 2014.)
