Undue Influence in California Probate | Probate Attorneys in Roseville, CA

What Is Undue Influence?

Undue influence occurs when a person in a position of trust, authority, or intimacy uses that power to override the free will of an individual—typically an elderly or vulnerable person—in the making of a will, trust, or other estate planning document. Rather than reflecting the true wishes of the decedent, the resulting document reflects the agenda of the influencing party.

California law specifically addresses undue influence in the context of both probate and elder abuse. Under California Probate Code § 86 and Welfare & Institutions Code § 15610.70, undue influence is defined with reference to vulnerability, apparent authority, the tactics used, and the equity of the resulting transaction.

Common Signs of Undue Influence

Undue influence can be difficult to detect, particularly when the influencing party has worked to isolate the victim from family and friends. Common indicators include:

• A sudden or unexplained change in estate planning documents, particularly late in life or during illness

• A new or recently prominent person—caregiver, neighbor, or romantic interest—who becomes the primary beneficiary

• Isolation of the decedent from longtime family members and advisors

• Evidence that the decedent lacked the capacity or independence to resist pressure

• The influencing party’s involvement in drafting, arranging, or witnessing the documents

How Undue Influence Is Proved in California

In California, the party challenging a will or trust on the basis of undue influence bears the initial burden of proof. However, when a fiduciary relationship exists between the decedent and the alleged influencer, California law creates a presumption of undue influence—shifting the burden to the beneficiary to prove the transaction was proper.

Our attorneys conduct a thorough investigation of the facts, including medical records, financial transaction history, witness accounts, and the timeline of estate document changes, to build a compelling evidentiary record on your behalf.

Remedies When Undue Influence Is Established

If undue influence is successfully proven, a California court may invalidate the affected will, trust, or specific provisions within those documents. The estate would then be distributed according to a prior valid document or California’s intestate succession laws. In cases involving elder financial abuse, additional civil remedies and attorney fee awards may be available.
