Since 2005, our litigation-only firm has helped families protect rightful inheritances and vulnerable elders in California probate courts.

Our attorneys do not dabble in estate planning or document drafting. We litigate. Every case is handled by experienced trust and probate litigators who understand how California judges evaluate evidence, credibility, and fiduciary conduct.

Clients often come to us after months or years of frustration, when a trust amendment suddenly appears, a trustee refuses to account, or a vulnerable parent was pressured into changes that make no sense. We step in with clarity, strategy, and courtroom readiness.

From our Irvine office near John Wayne Airport and the Irvine Spectrum, and our San Diego office serving clients near UTC and La Jolla, we represent families throughout Southern California and statewide. If you believe a trust does not reflect the true intent of the person who created it, you deserve answers and strong legal advocacy.

A conversation with a California trust contest attorney can bring direction during an overwhelming time. We are here to guide you, fight for you, and protect what matters most.

Understanding Trust Contests and Why They Matter in California

A trust contest is a legal action filed in California probate court to challenge the validity, interpretation, or administration of a trust. These cases arise when a trust does not reflect the true wishes of the person who created it, or when a trustee’s conduct harms beneficiaries. 

Trust contests matter in California because trusts are widely used to avoid probate and manage family wealth. When something goes wrong, the impact is immediate and personal. Assets can be frozen. Distributions can be delayed. Family relationships can fracture. 

California law places a high value on intent. The probate court’s role is to determine whether the trust truly reflects the settlor’s intent at the time it was created or amended. That determination depends on evidence, credibility, medical records, financial behavior, and witness testimony. 

If you suspect a trust was changed under pressure, created without capacity, or administered unfairly, early legal guidance can protect your rights and preserve critical evidence. Speaking with a California trust contest attorney helps you understand your options and take action before harm becomes permanent.

Legal Grounds to Contest a Trust in California

California law allows a trust to be contested only on specific legal grounds.

Undue Influence
Undue influence occurs when someone exerts pressure that overcomes the free will of the person creating or amending a trust. This often involves caregivers, relatives, or trusted advisors who isolate the trust creator and benefit from sudden or drastic changes. 

California courts closely examine vulnerability, dependency, and unnatural distributions when evaluating these claims.

Lack of Mental Capacity
A trust or amendment may be invalid if the person creating it lacked the mental capacity to understand the nature of their actions. Medical records, cognitive diagnoses, medication use, and witness testimony play a critical role. Capacity is evaluated at the exact time the trust document was signed, making timely investigation vital.

Fraud or Forgery
Fraud involves intentional deception that causes someone to sign a trust they did not fully understand. Forgery involves falsified signatures or altered documents. These cases often require handwriting analysis, document examination, and detailed financial review to uncover how the trust was manipulated.

Improper Execution
California law requires trusts to meet specific legal formalities. Missing signatures, improper amendments, or violations of statutory requirements can render a trust or amendment invalid. Courts look closely at how and when documents were prepared and executed.

Elder Financial Abuse
When a trust dispute involves the exploitation of an elderly or dependent adult, California courts apply heightened scrutiny. Financial abuse claims often overlap with undue influence and can lead to additional remedies, including damages and attorney fee recovery.

How the Trust Contest Process Works Under California Law

Understanding how the trust contest process works helps families avoid missteps that can weaken an otherwise valid claim.

1. Case Evaluation and Evidence Review
The process begins with a detailed review of the trust, amendments, financial records, medical history, and communications. Early evidence preservation is critical because documents and witnesses can disappear quickly.

2. Filing a Trust Petition Under Probate Code §17200
A trust contest is initiated by filing a petition. The petition must clearly state the legal grounds and requested remedies.

3. Notice, Responses, and Court Oversight
Once filed, all interested parties receive formal notice. Trustees and beneficiaries may file objections or responses. The court actively manages the case, setting deadlines and hearings that require strict compliance with local probate rules.

4. Discovery and Investigation
Both sides exchange documents, take depositions, and consult professionals when necessary. This phase determines whether the case resolves early or proceeds toward trial.

5. Mediation, Settlement, or Trial
Some trust contests resolve through court-ordered mediation. Others proceed to evidentiary hearings or trial, where a judge decides the outcome. Litigation readiness matters because California courts expect organized evidence and experienced advocacy.

Notable Trust Litigation Cases in Southern California

California trust law is shaped by court decisions that clarify how judges evaluate trustee conduct, beneficiary rights, and the intent behind a trust. Understanding how courts have ruled in prior cases helps set realistic expectations in modern trust contests.

One frequently cited case in Southern California trust litigation is Estate of Giraldin (2012). In this California Supreme Court decision, the court clarified that trustees owe enforceable duties not only to the trust itself, but also to beneficiaries when misconduct harms their interests. 

This case is regularly referenced in Orange County and San Diego trust disputes involving trustee self-dealing and breach of fiduciary duty.

These cases reinforce an important reality. California courts closely scrutinize trustee behavior and the circumstances surrounding trust changes, especially when vulnerable individuals are involved. Outcomes depend on evidence, preparation, and the ability to present a clear legal narrative.

Amy and her team are excellent. They formed the Special needs trust form my daughter and helped us with the administration of it during my daughter’s life. The law firm who we were dealing with the claim of the accident and who we are very grateful with, because of their humbleness and experience in accidents, they did what others firms didn’t even consider trying. After the accident case was settled, we needed a trust to receive the funds on behalf of my daughter and they try to set it up, but after a few hearing with the courthouse they just said, go see Amy, We did, and oh my goodness, they were able to set and get it approved in just one hearing. This is amazing for what I saw in the court room. Some cases NOT HANDLED by Amy, that I was able to hear during the several times we were in the court room with the accident attorney, some cases were already into 2 years and not resolved. When Amy took our case in her hands. Her staff was so professional that in the first try, the trust was approved by the court. In addition, they were very caring and supportive to us during the time of our relationship as client and attorney, and even though our relationship has ended after the passing of our daughter, I know that if in any case I need someone who I can fully trust blindly this is Amy and her team. If you are looking for fast, reliable and a accurate results look no more, Amy and associates is who you are looking for.

Sincerely

Sergio Mendoza

Joe Patton has been a terrific estate planning resource. He’s very knowledgeable and well-versed. He’s a higher-end attorney but he helped us understand the complexities of setting up a revocable trust and took the time to answer all of our questions candidly (and make suggestions surrounding those hypothetical circumstances). My husband and I feel very fortunate to know him and to know now that our affairs are in order should the unthinkable occur. We’d both highly recommend his counsel as we know him to be very hard-working and honest. He’s a good guy!
