What Happens When Undue Influence Results in an Estate Plan Change?

Written by David L. Dingwell | Nov 13, 2025 1:59:59 PM

Both fictional and real-life accounts of undue influence have fascinated us for generations. Hollywood renditions of shocked family members during readings of a deceased person’s will are a common dramatic story arc. When family members find out that a change was made that disinherits those who would normally inherit the family fortune in favor of some unusual beneficiary, the family members scramble to hire lawyers to contest the will.

While real-life incidents of undue influence may be less dramatic than Hollywood versions, undue influence is not at all uncommon in today’s world. It has become a growing problem that plays out repeatedly. Greed, desperation, sense of entitlement, and other ill motives frequently lead to persons taking advantage of elderly persons or other persons who are not sufficiently able to say “no.” 

Persons who engage in acts of undue influence may be family members, friends, neighbors, caregivers, or other persons who become close to the susceptible person who is victimized. Worse yet, many times, undue influence may not be discovered until after the death of the victim. Family members or those who originally stood to inherit are left to sort out exactly what happened, when, and what can be done about it.  

What Is the Meaning of “Undue Influence”? 

Under Ohio law, there are four elements of undue influence: 

  1. A susceptible person (because of age, illness, weakened mental state, reliance upon the influencer, or similar factor); 
  2. The influencer had the opportunity to exert control or influence over the susceptible person; 
  3. The influencer had the intent to influence the susceptible person to benefit themselves or persons for whom the influencer wanted to benefit at the expense of the susceptible person’s natural heirs; 
  4. A result that was caused by the influence; e.g. the susceptible person made the change to the will to benefit the influencer.

All four elements must be proven in order to demonstrate that undue influence was exerted. 

Is Physical or Emotional Abuse a Requirement to Prove Undue Influence? 

One common misperception is that victims are required to prove some type of physical or emotional abuse, or threat of abuse to prove undue influence. Abuse or threats of abuse are not required. Even subtle efforts may constitute undue influence. 

It is also not necessary to prove that the victim of undue influence was mentally incompetent. Even persons who are capable of making decisions for themselves are able to be unduly influenced so long as some factor of susceptibility is demonstrated such as physical illness or physical infirmity. 

Typical indicators of persons attempting to unduly influence a susceptible person include: 

  1. Isolating the susceptible person from other friends or family members; 
  2. Limiting the susceptible person’s ability to communicate with others; 
  3. Increasing the susceptible person’s reliance upon the influencer; 
  4. The influencer suddenly becoming unusually involved in the susceptible person’s financial, legal, and/or medical decisions; 
  5. Drastic changes to estate planning or financial decisions; 
  6. Unusual changes to patterns of spending by the susceptible person.

What Transactions Can Be Affected by Undue Influence, and What Is the Result? 

In the estate planning context, undue influence can apply to changes in a person’s last will and testament, their trust documents, or their beneficiary designations. Undue influence can also result in large gifts of money or property. 

When there is a finding of undue influence, Courts will fashion remedies that will nullify the effect of the undue influence if at all possible in order to void the change that was wrought by the undue influence. If a will was changed because of undue influence, the prior will that was executed before the change will control the disposition of the deceased person’s property. If there was no will, then the deceased person’s estate is distributed in accordance with the laws of intestate succession. If a gift was made, the property that was gifted must be returned. 

A finding of undue influence may also result in victims being able to sue the influencer/wrongdoer for money damages and attorney fees. The goal is to make the victims whole.
