Key Takeaways

  • In California, trust litigation begins with a petition filed in probate court.
  • Under the California Probate Code, strict notice and service requirements apply.
  • Most cases involve discovery, motions, and court-supervised hearings before trial.
  • Settlement can occur at any stage of the case.
  • Trust litigation in California rarely happens overnight.
  • As a result, it follows a strict legal process governed by the California Probate Code.

What Triggers California Trust Litigation

Trust disputes often arise when:

  • The trustee refuses to provide an accounting (Probate Code §§ 16060, 16062)
  • A beneficiary alleges breach of fiduciary duty
  • In other cases, beneficiaries challenge amendments based on undue influence or lack of capacity
  • The trustee delays distributions without reason or justification
Before trust litigation starts, many disputes begin with requests for information or demands for compliance. Therefore, when those efforts fail, court involvement becomes necessary.
At The Grossman Law Firm, Attorney Scott Grossman represents beneficiaries and heirs in probate and trust litigation throughout California. Below is a practical overview of how a trust dispute typically progresses in California.

Stage 1: Pre-Litigation Investigation and Early Resolution

Before filing a petition, a careful review of the trust document, financial records, and relevant communications is essential.

Evaluating Legal Grounds

Common legal claims in California trust litigation include:
  • Breach of fiduciary duty (Probate Code § 16400 et seq.)
  • Removal of trustee (Probate Code § 15642)
  • Surcharge for financial harm to the trust (Probate Code § 16440)
  • Further, contesting the validity due to undue influence or incapacity
Each claim requires specific factual support. Not every disagreement justifies a lawsuit.

Considering Early Resolution

In many cases, mediation is explored before formal litigation. Early resolution can reduce costs and, in some situations, preserve family relationships. Nevertheless, when informal efforts fail, filing a petition becomes the next step.

Stage 2: Filing a Trust Petition in Probate Court

When these efforts fail, the dispute formally commences with a petition filed in the probate division of the California Superior Court.

What the Petition Must Include

The petition must clearly explain:

  • The trust at issue and the parties involved

  • The legal grounds for relief

  • The specific Probate Code sections relied upon

  • The remedies requested

A well-drafted petition frames the issues and often shapes how the case unfolds.

After filing, the court sets a hearing date. In short, that hearing becomes the first opportunity for the judge to evaluate the dispute and determine the next steps.

Stage 3: Notice and Service Requirements

Who Must Receive Notice

Once the petition is filed, the focus shifts to notice. As a result, California law requires that all interested parties be properly informed of both the petition and the scheduled

hearing.

Typically, notice goes to:

  • The acting trustee
  • All beneficiaries named in the trust
  • Heirs at law, depending on the nature of the petition
For that reason, notice is more than a courtesy. It must comply with statutory requirements regarding timing and method of service. If notice is incomplete or defective, the court may continue the hearing. Or additionally, refuse to grant relief until proper service is completed.
These procedural details matter. This is crucial to the case. Even a strong legal claim can be delayed if deadlines or notice requirements are overlooked.

Stage 4: Discovery in a California Trust Lawsuit

Common Discovery Tools in Trust Litigation

If the dispute does not settle at the beginning, the case proceeds to discovery. This is the evidence-gathering phase.
Each side has the right to request information and documents relevant to the case.
In trust litigation, that process commonly includes:
  • Depositions, where witnesses answer questions under oath before trial
  • Interrogatories, which are written questions that must be answered under penalty of perjury
  • Requests for production of documents, such as bank statements, accountings, and communications
  • Subpoenas directed to financial institutions or third parties holding relevant records
Discovery is frequently the turning point in a case. It can uncover how trust funds were handled, whether distributions were delayed without justification, or whether someone exerted undue influence over the settlor.
Not surprisingly, disagreements often arise over what must be produced. If a party refuses to provide requested information, the court can order compliance. In some instances, sanctions may follow.

Stage 5: Pre-Trial Motions and Court Hearings

Before trial, the court may hear various motions.
These can include:
  • Motions to dismiss
  • Motions for summary judgment
  • Evidentiary motions
In probate court, multiple hearings may occur over the course of several months. The judge often closely manages the case.
As a result, settlement conferences may also be held during this phase.

Stage 6: Trial Preparation

As the trial approaches, preparation intensifies.

Building a Trial Strategy

This includes:
  • Identifying key witnesses
  • Sorting financial evidence
  • Preparing expert testimony, if necessary
  • Drafting trial briefs
In trust litigation, trials are typically bench trials, meaning a judge decides the case. Jury trials are uncommon in probate matters.
Strong preparation regularly influences settlement discussions as well.

Stage 7: Trial in Probate Court

At trial, both sides present evidence and legal arguments.

The trial process normally includes:

  • Opening statements
  • Witness testimony
  • Cross-examination
  • Presentation of exhibits
  • Closing arguments
Because probate trials are usually decided by a judge, credibility and documentary evidence often hold considerable importance.
As a result, after trial, the court may issue a written ruling or take the matter under submission.

Stage 8: Post-Trial Motions and Appeals

Following judgment, parties may file post-trial motions. These may challenge mistakes or request clarification.
Appeals must typically be filed within strict deadlines, often 60 days from notice of entry of judgment. Appeals focus on legal error, not re-trying facts.
Further, appeals in litigation add time and expense, so careful evaluation is important before proceeding.

Stage 9: Settlement at Any Stage

Trust litigation can settle at virtually any point.
Settlement agreements must be carefully drafted to:
  • Define payment terms
  • Address trustee removal or resignation
  • Allocate attorney’s fees
  • Release future claims
Consequently, upon approval, the settlement becomes binding.

Stage 10: Costs and Attorney’s Fees in Trust Litigation

Trust litigation can be expensive. Costs may include:
  • Attorney’s fees
  • Court filing fees
  • Expert witness fees
  • Discovery costs

When Courts Shift Fees

Under certain circumstances, California courts may impose:
  • Surcharge a trustee personally for losses
  • Award attorney’s fees against a breaching fiduciary
  • Approve payment of fees from the trust
As a result, each case turns on its specific facts and applicable Probate Code provisions.
