Not every disagreement about a trust rises to the level of litigation. Many concerns can be resolved through open communication between trustees and beneficiaries. But there are situations where legal action becomes the only way to protect your rights and honor a loved one’s intentions.

Communication has broken down

When a trustee stops responding to reasonable requests for information or refuses to provide accountings, beneficiaries may have no choice but to involve the court. California law requires trustees to keep beneficiaries reasonably informed about trust administration. If those lines of communication have closed, legal intervention can reopen them.

The trustee isn’t acting in good faith

If you believe the trustee is mismanaging trust assets, making self-interested decisions, or failing to follow the trust’s terms, these are serious concerns. A trustee has a fiduciary duty to act in the best interests of the beneficiaries. When that duty is being violated, litigation may be the only way to hold the trustee accountable.

The validity of the trust is in question

Sometimes the trust document itself is the problem. If you suspect a loved one was pressured into creating or changing their trust, or lacked the mental capacity to understand what they were signing, you may have grounds to challenge the trust’s validity.

Common Grounds for Trust Litigation in California

California’s Probate Code provides several legal bases for trust disputes. Here are the most common grounds our attorneys handle.

Undue influence

Undue influence occurs when someone exerts excessive pressure on the trust creator (known as the settlor) to change the trust in their favor. This often involves a caregiver, family member, or close advisor who takes advantage of the settlor’s vulnerability. If undue influence is proven, the court can invalidate the affected provisions.

Lack of capacity

For a trust to be valid, the settlor must have had the mental capacity to understand what they were signing. If the settlor was suffering from dementia, cognitive decline, or another condition that impaired their judgment when the trust was created or amended, the document may be challenged.

Breach of fiduciary duty

Trustees are held to a high standard under California law. They must manage trust assets prudently, avoid conflicts of interest, keep accurate records, and distribute assets according to the trust’s terms. Under Cal. Prob. Code § 16420, if a trustee commits or threatens to commit a breach of trust, a beneficiary may commence a proceeding to compel the trustee to perform their duties, redress the breach, or remove the trustee.

Trustee removal

When a trustee is failing to fulfill their responsibilities, California law provides a clear pathway for removal. Under Cal. Prob. Code § 15642, grounds for removal include breach of trust and insolvency or unfitness to administer the trust. The court may also remove a trustee who is substantially unable to manage the trust’s financial resources or otherwise unable to execute the duties of the office. A beneficiary, co-trustee, or settlor can petition the court.

Trust modification and interpretation disputes

Sometimes the language in a trust is ambiguous or circumstances have changed so significantly that modification is appropriate. Disputes can also arise when parties disagree about what certain provisions mean. Under Cal. Prob. Code § 17200, a trustee or beneficiary may petition the court concerning the internal affairs of the trust or to determine the existence of the trust. This includes requesting interpretation of trust terms and approval of modifications.

How Trust Litigation Works in California

Understanding the process can ease some of the anxiety that comes with a legal dispute. Here’s what a typical California trust litigation case looks like.

Case evaluation

Every case begins with a thorough review of the trust documents, relevant communications, and the facts of your situation. Our attorneys assess the strength of your position, identify potential challenges, and develop an initial strategy tailored to your goals.

Filing a petition with the court

Trust litigation in California begins by filing a petition in the probate division of the Superior Court. Under Cal. Prob. Code § 17200, a trustee or beneficiary may petition the court concerning the internal affairs of the trust. The petition is typically filed in the county where the principal place of administration of the trust is located.

Discovery

Once the petition is filed, both sides gather evidence through the discovery process. This can include document requests, depositions, and written interrogatories. Discovery is often the most time-intensive phase, but it’s also where strong cases are built. The evidence uncovered during discovery frequently shapes the direction of the entire case.

Mediation and settlement negotiations

Many trust disputes are resolved through mediation or settlement negotiations before reaching trial. A skilled mediator can help both sides find common ground, and a negotiated resolution is often faster, less expensive, and less emotionally draining than litigation. Our attorneys always evaluate whether settlement serves our client’s interests before recommending a path forward.

Trial before a judge

If the dispute cannot be resolved through negotiation, the case proceeds to trial. Under Cal. Prob. Code § 17006, there is no right to a jury trial in proceedings concerning the internal affairs of trusts. That means trust litigation cases are decided by a judge. Having attorneys who are thoroughly prepared for trial can make a significant difference in the outcome of your case.

How Weiner Law Approaches Trust Litigation

Our approach to California trust litigation is built on three principles: thorough preparation, clear communication, and strategic advocacy.

Thorough preparation

We dig into the details. Every document, every communication, and every financial record matters in trust litigation. Our attorneys conduct a comprehensive review and leave nothing overlooked when building your case, because preparation is the foundation of effective advocacy.

Clear communication

Trust disputes are stressful, and the legal process can feel overwhelming. We believe you deserve to understand what’s happening at every stage. Our attorneys explain complex legal concepts in plain language and keep you informed throughout so you’re never left wondering what comes next.

Strategic advocacy

Not every trust dispute needs to go to trial, and not every dispute can be resolved without one. We develop a strategy tailored to your specific situation, whether that means focused negotiation, mediation, or courtroom litigation. The right approach depends on the facts of your case, and we’re prepared for all of them.

With offices in San Diego (402 W Broadway, Suite 400-B) and Los Angeles (445 S Figueroa St, Suite 3100), Weiner Law serves clients in trust litigation matters throughout California.

Whether You’re a Beneficiary or a Trustee

Trust litigation isn’t one-sided. Both beneficiaries and trustees face unique challenges, and our attorneys represent clients on both sides of these disputes.

For beneficiaries

If you believe your inheritance is being mismanaged or that the trust doesn’t reflect your loved one’s true wishes, you have legal options. California law gives beneficiaries the right to petition the court for information, accountings, and even removal of a trustee who isn’t acting in good faith. You don’t have to sit by while trust assets are mishandled.

For trustees

Serving as a trustee comes with significant legal responsibilities, and allegations of wrongdoing can be both stressful and personally damaging. If you’re a trustee facing a dispute, having legal counsel with experience in these matters is critical. Our attorneys help trustees understand their obligations, respond to petitions, and defend against unfounded claims.

Frequently Asked Questions About California Trust Litigation

How long do I have to contest a trust in California?

Time limits for contesting a trust are strict. Under Cal. Prob. Code § 16061.7, a trustee must notify beneficiaries and heirs when a trust becomes irrevocable. You may not bring an action to contest the trust more than 120 days from the date the trustee’s notification is served upon you, or 60 days from the date a copy of the trust terms is delivered to you during that 120-day period, whichever is later. Because these deadlines are firm, it’s important to consult an attorney as soon as you receive a trustee notification.

Can I remove a trustee in California?

Yes. Under Cal. Prob. Code § 15642, a trustee may be removed in accordance with the trust instrument, by the court on its own motion, or on petition of a settlor, cotrustee, or beneficiary. Grounds for removal include breach of trust and insolvency or unfitness to administer the trust. Removal isn’t automatic. The court will consider all the circumstances before making a decision.

What does trust litigation cost?

The cost of trust litigation varies depending on case complexity, the amount in dispute, and whether the matter goes to trial. During your consultation, our attorneys will discuss fee structures and help you understand what to expect financially. In some cases, the court may order that attorney’s fees be paid from the trust itself.

Do trust disputes always go to trial?

No. Many trust disputes are resolved through mediation or settlement negotiations. California courts often encourage or require mediation before a case can proceed to trial. That said, some disputes require a judge’s decision. Our attorneys prepare every case as if it will go to trial, so we’re ready no matter what direction your case takes.
