5 Most Common Court Petitions in California Trust and Estate Battles

Publication Date August 18, 2026 in Trust Litigation

I am Michael Hackard, founder of Hackard Law. Over five decades of practice, I have fought for heirs, beneficiaries, and elder abuse victims in California probate and superior courts. I have authored four published books on inheritance protection and produced more than 1,000 educational videos that have reached over seven million viewers. Families navigating trust and estate disputes in Sacramento, the San Francisco Bay Area, and Los Angeles frequently ask me the same question: are other families going through what we are going through? The answer, almost always, is yes.

Estate battles carry their own distinctive troubles. They unfold inside families, often after years of quiet tension, and they arrive at the courthouse carrying grief, confusion, and betrayal alongside the legal paperwork. After litigating these cases across California superior courts, certain patterns emerge with striking regularity. Five court petitions appear again and again. Understanding them can help you recognize where your own dispute may be headed – and what it takes to pursue justice effectively.

Hackard Law provides contingency fee representation for qualified cases, meaning no upfront costs to get started. To speak with our team, call (916) 313-3030.

Quick Summary

California trust and estate battles follow recognizable patterns, and five specific court petitions appear most frequently in superior court litigation.

Petitions alleging wrongful acquisition and misappropriation of trust assets by a former trustee
Petitions to remove a co-trustee and appoint a successor fiduciary under court supervision
Ex parte petitions to suspend a co-trustee’s powers and install a temporary successor trustee
Petitions compelling forensic accounting and instructing a trustee on real property matters
Petitions to invalidate a trust amendment based on forgery or undue influence

Petition 1: Wrongful Acquisition and Misappropriation of Trust Assets

Former trustees who have embezzled trust assets for personal gain are the target of one of the most common petitions. According to these petitions, the trustee misappropriated funds that belonged to the trust and its beneficiaries by transferring, diverting, or otherwise violating their fiduciary duty.

Misappropriation often surfaces only after the trustee has left the role – sometimes after the death of the settlor – when beneficiaries finally gain access to records that were previously withheld. Bank statements, property transfers, and financial account histories can reveal a pattern of self-dealing that accumulated over months or years.

Hackard Law pursues these claims aggressively, drawing on forensic accounting and documentary discovery to reconstruct what was taken and when. You can learn more about how beneficiaries can respond when trustees delay or withhold their rightful distributions.

Case Pattern: Trustee Asset Diversion

A family discovered after their parent’s death that the sibling serving as trustee had transferred six figures from the trust account into a personal account over a three-year period. A petition for misappropriation, supported by bank records obtained through discovery, led to a negotiated recovery of the diverted funds before trial.

Petition 2: Removal of a Co-Trustee and Appointment of a Successor Fiduciary

When a co-trustee is failing in their duties – whether through neglect, self-dealing, or active misconduct – a petition for removal and replacement becomes necessary. California courts have authority to remove a trustee and appoint a professional fiduciary to step in, placing the trust under court supervision during the transition.

These petitions are not filed lightly. Courts expect petitioners to document the trustee’s failures with specificity. That means gathering correspondence, accounting records, trust documents, and witness declarations that together paint a clear picture of why the current trustee cannot continue.

For families in Sacramento County, understanding the full landscape of probate and trust litigation helps set realistic expectations about the process and timeline.

Petition 3: Ex Parte Suspension of a Co-Trustee’s Powers

Some situations cannot wait for a standard hearing date. When a co-trustee is actively dissipating assets, making unauthorized transfers, or creating irreversible harm to the trust estate, an ex parte petition allows the court to act immediately – suspending the trustee’s powers and appointing a temporary successor without advance notice to the opposing party.

Ex parte relief is reserved for genuine emergencies. Courts scrutinize these requests carefully, and a successful ex parte petition requires a compelling showing of imminent harm. Once granted, the temporary successor fiduciary takes control while the full removal proceeding moves forward on a regular schedule.

This type of emergency action is one reason why trustee accountability matters so much – delay in confronting misconduct can allow irreversible damage to accumulate.

Case Pattern: Emergency Trustee Suspension

A co-trustee began liquidating trust real estate and moving proceeds offshore shortly after the settlor’s death. Beneficiaries sought emergency ex parte relief. The court suspended the trustee’s powers within days, freezing further transfers and preserving the remaining estate for proper administration.

Petition 4: Compelling Forensic Accounting and Trustee Instruction on Real Property

Some petitions focus less on removing a trustee and more on forcing transparency. A petition to compel forensic accounting demands that the court order an independent review of the trust’s financial records – every transaction, every disbursement, every transfer – to determine whether the trustee has administered the trust properly.

When real estate is at stake, these petitions may also ask the court to give the trustee instructions on how to maintain, sell, or distribute the property in accordance with the terms of the trust. In a California trust, real estate is frequently the biggest single asset, and disagreements over how to handle it can have disastrous financial effects if they are not settled.

Michael Hackard identifies these petitions as particularly powerful tools because they shift the burden to the trustee to justify every financial decision made during their tenure. The Sacramento estate lawyer resources at Hackard Law provide further context on how these proceedings unfold.

Petition 5: Invalidating a Trust Amendment Based on Forgery or Undue Influence

Perhaps the most consequential petition in trust litigation is one that challenges the validity of a trust amendment itself. These petitions allege that a change to the trust – often one that dramatically shifted assets away from the original beneficiaries – was the product of forgery, undue influence, or lack of capacity.

In many of these cases, elder financial abuse and undue influence are major factors. A vulnerable settlor may sign amendments they do not fully understand, or that do not accurately reflect their true wishes if they are cut off from family and dependent on a caregiver or opportunistic relative. When that manipulation can be demonstrated, California law offers significant remedies.

In these petitions, Hackard Law also seeks an order preventing trust funds from being used to pay for the legal defense of those who allegedly committed the fraud. That remedy matters – it prevents the trust estate itself from being depleted to shield the very conduct that harmed the beneficiaries. For a broader look at elder financial exploitation and how California law addresses it, our firm has assembled extensive resources on the subject.

For many years, I have supported families who found out—often too late—that someone they trusted had subtly changed the rules. After that revelation, a family’s division is frequently too deep for any judgment to heal. However, the financial cost can be mitigated, and an unwavering dedication to the truth replaces what dishonesty attempted to steal.

What to Do Next

Look for any recent changes to a trust document, especially amendments made during a period of illness or isolation.
Get copies of trust accountings and bank statements as early as possible – delays can allow records to disappear.
Try to avoid confronting a suspected trustee directly before speaking with an attorney, as it can complicate the legal strategy.
Look for signs of isolation, sudden dependency, or new relationships that may indicate undue influence was at work.
Get a timeline of events in writing – when the settlor’s health changed, when documents were signed, and who was present.
Try to avoid accepting verbal assurances from a trustee that everything is in order without seeing the actual records.
Look for patterns of financial transfers that do not align with the trust’s stated purposes.
