What Is Undue Influence?

When someone suddenly changes a will or trust near the end of their life, family members often assume it was simply their loved one’s decision.

Sometimes it was.

Other times, someone spends months or years controlling conversations, limiting family contact, creating dependency, and quietly influencing decisions.

This is known as undue influence.

Attorney Scott Grossman at The Grossman Law Firm represents beneficiaries and heirs across California who believe a will or trust no longer reflects their loved one’s true wishes. Many cases begin with the same question:

“Something doesn’t feel right. Is this legal?”

A Common Example of Undue Influence

The names, facts, and circumstances in this example have been modified for privacy.

For years, Robert spoke with his three children every week.

After his wife passed away, his sister Karen offered to help with doctor’s appointments and errands. At first, everyone appreciated the assistance.

Over time, things changed.

Karen gradually took control of Robert’s daily life. She screened his phone calls, discouraged family visits, managed his medications and appointments, and became the primary point of contact for nearly everyone around him.

Months later, Karen drove Robert to an attorney’s office to sign new estate documents.

His longtime trust, which had divided everything equally among his children, was replaced by a new plan that left most of the estate to Karen.

After Robert passed away, his children were shocked.

The attorney who prepared the documents had only met Robert once. No one outside Karen had been involved. The children later learned Karen had been present for nearly every meeting and had even helped gather information used to prepare the new documents.

Their concern wasn’t simply that the trust changed.

It was everything that had happened before it changed.

After speaking with a probate litigation attorney, Robert’s children learned they might have grounds to challenge the trust for undue influence. They also had another concern: they could not afford years of litigation to recover their inheritance.

How a Contingency Fee Helped the Family Pursue Their Claim

Because the estate was substantial and the facts suggested a potentially valid claim, the attorney explained that the case might qualify for a contingency fee. Instead of paying attorney fees up front, the family could pursue the case without incurring them unless money or property was ultimately recovered.

Not every undue influence claim qualifies for a contingency fee. Whether this type of arrangement is available depends on the specific facts, the available evidence, the value of the assets involved, and other factors. For beneficiaries who believe they have been wrongfully denied an inheritance but cannot afford hourly legal fees, a contingency fee may make it possible to pursue a claim that would otherwise never reach the courtroom.

Signs Someone May Be Exercising Undue Influence

Undue influence rarely happens overnight.

Instead, it often develops gradually as one person gains more control over another.

Some common warning signs include:

Family members are discouraged from visiting or communicating.
Phone calls suddenly stop or are monitored.
One individual controls transportation, finances, or medical appointments.
The vulnerable person becomes increasingly isolated.
Estate planning documents change dramatically late in life.
The person benefiting from the changes arranged the attorney or was present during meetings.
The new plan favors one person without a clear explanation.

One sign alone does not necessarily prove undue influence.

However, when several of these circumstances occur together, further investigation may be warranted.

How California Courts Evaluate Undue Influence

California courts do not simply ask whether someone persuaded another person.

People are allowed to express opinions, make suggestions, and even encourage certain decisions.

The legal question is whether someone’s influence became so significant that it replaced the person’s own independent judgment.

Courts often examine factors such as:

Vulnerability

Was the individual elderly, ill, grieving, or experiencing cognitive decline?

Authority

Did the alleged influencer control daily care, finances, medications, or access to other family members?

Actions Used to Influence

Did they isolate the individual, pressure them, control information, or arrange legal appointments?

The Result

Did the estate plan suddenly change in a way that primarily benefited the person exercising influence?

Rather than focusing on a single event, courts typically consider the overall pattern of behavior leading up to the execution of the document.

What Happens if Undue Influence Is Proven?

If a California probate court determines that a will or trust resulted from undue influence, the court may invalidate all or part of the document.

Depending on the circumstances, beneficiaries may also pursue additional claims involving:

Trust contests
Will contests
Financial elder abuse
Breach of fiduciary duty
Recovery of wrongfully transferred assets

Every case is different, so acting early matters. Financial records, medical records, witness statements, emails, texts, and other evidence can be harder to get as time passes. If you suspect undue influence played a role, The Grossman Law Firm can evaluate your situation and help you take steps to preserve important evidence.

What May Determine Whether a Case Qualifies for a Contingency Fee

Attorneys often consider:

Whether money or property may be recovered through litigation.
The value of the assets involved.
The strength of the available evidence.
The nature of the alleged misconduct, such as undue influence, self-dealing, or breach of fiduciary duty.

If concerns about legal fees have kept you from pursuing your inheritance, The Grossman Law Firm can evaluate your situation and determine whether your case may qualify for a contingency fee arrangement.

FAQ

Is isolation evidence of undue influence?

Isolation alone does not prove undue influence, but it is one of the most common warning signs courts consider when evaluating these claims.

Can undue influence invalidate a trust?

Yes. If a court determines an irrevocable trust or trust amendment resulted from undue influence, it may invalidate the affected provisions.

How do you prove undue influence?

Evidence may include medical records, witness testimony, communications, financial records, estate planning documents, and proof showing a pattern of isolation or manipulation.
