Trustee Removal in California: Substance Abuse, Undue Influence, and Other Good Cause
Publication Date October 1, 2026 in Trust Litigation
When a Trustee Cannot Be Trusted
I am Michael Hackard, founder of Hackard Law, and over five decades of practice I have fought for heirs, beneficiaries, and elder abuse victims across California – from Sacramento to the San Francisco Bay Area to Los Angeles. I have written four published books on inheritance protection and produced more than 1,000 educational videos that have reached over seven million viewers. That body of work reflects one consistent reality: when a trustee loses the ability or the will to act honestly, families suffer.
Trustee removal is one of the most consequential remedies in California trust law. Courts do not grant it lightly, but they do grant it – and the grounds are broader than most beneficiaries realize. Substance abuse, undue influence, refusal to distribute assets, and a range of other misconduct can each justify removing a trustee and replacing them with someone who will actually serve the trust’s purposes.
Hackard Law provides contingency fee representation for qualified trust and estate cases – no upfront costs to you. If your family is facing trustee misconduct, call us today at (916) 313-3030.
Quick Summary
California courts may remove a trustee for cause where the conduct of the trustee poses a threat to the interests of the beneficiaries or to the integrity of the trust itself. Substance abuse, susceptibility to undue influence and willful refusal to distribute are the most litigated grounds.
- Trustees who are substantially unable to resist fraud or undue influence can be removed
- Habitual substance abuse by a trustee is recognized grounds for removal
- Punitive refusal to make distributions can constitute actionable misconduct
- Criminal convictions and improper asset management are additional removal triggers
- Courts weigh the totality of conduct, not just isolated incidents
The Undue Influence Problem Inside the Trust
Undue influence is not limited to the moment a trust document is signed. It can infect the ongoing administration of a trust when a trustee becomes unable – or unwilling – to resist pressure from a favored beneficiary. California Probate Code section 15642 specifically identifies a trustee who is “substantially unable to resist fraud or undue influence” as subject to removal.
This often happens in practice in families where there is a close personal relationship between a beneficiary and a trustee. That relationship provides leverage. The trustee may allow the beneficiary to live rent-free in trust-owned property, advance funds that other beneficiaries never get, or simply ignore the erosion of trust assets. It’s not always dramatic behavior. Sometimes it’s a slow accumulation of favoritism, which, taken together, shows a trustee who has lost independent judgment.
For a deeper look at how undue influence operates in California estate law, the undue influence in California estate law resource at Hackard Law walks through the legal standards courts apply.
Case Pattern: A Trustee Under the Influence of a Beneficiary
In one pattern Hackard Law has litigated, a trustee repeatedly transferred cash advances to a single adult child while the other beneficiaries received nothing. The trustee and that child had a close personal bond, and the financial records told the story plainly. When litigation commenced, the pattern of preferential transfers – combined with the trustee’s inability to articulate any trust-authorized basis for them – supported a successful removal petition.
Substance Abuse and Trustee Fitness
Under California law, a trustee can be removed for habitual use of drugs or alcohol. The trick is to display it”. I have participated in mediations where the trustee turns up visibly impaired, but demonstrating impairment to the standard the court demands takes preparation, paperwork, and perseverance.
Substance Abuse Evidence in Trustee Removal Cases Financial records evidencing erratic or unexplained transactions, testimony from family members or co-trustees, medical records if available, and patterns of decision-making that no sober fiduciary would engage in are examples of substance abuse evidence in cases of trustee removal. Courts want to see a pattern, not just one incident. In the presence of that pattern, there’s a strong case for removal.
Substance abuse also intersects with undue influence in a specific way: the impaired trustee becomes vulnerable to manipulation by the very beneficiary whose interests they are supposed to balance against all others. That combination – impairment plus a dominant beneficiary – is one of the most destabilizing dynamics in trust administration. The trust traps and undue influence resource at Hackard Law addresses how these patterns develop and how courts respond.
Refusal to Distribute and Other Misconduct
Beyond substance abuse and undue influence, California courts recognize a range of conduct that can justify removal under the “other good cause” standard. Refusal to make distributions is among the most common. When a trustee withholds distributions without legitimate justification – particularly when the refusal appears designed to punish or pressure certain beneficiaries – courts treat that as a breach of fiduciary duty.
Criminal convictions present a cleaner case. A trustee convicted of fraud, theft, or financial crimes has demonstrated, by the most authoritative possible finding, that they cannot be trusted with the assets of others. Courts have little difficulty removing trustees in those circumstances.
Improper investment decisions and failure to dispose of unproductive assets round out the picture. A trustee who concentrates trust assets in a single risky position, or who allows deteriorating property to sit in the trust rather than liquidating it, may be breaching the prudent investor standard that California law imposes. Beneficiaries harmed by those decisions have remedies – including removal and a surcharge action to recover losses.
For families dealing with a trustee who refuses to account for their actions, compelling a trustee accounting is often the first step toward building a removal case.
Case Pattern: Refusal to Distribute as a Pressure Tactic
In another type of trust litigation, a trustee with personal animosity toward a beneficiary stopped making distributions to that individual while continuing to distribute to others. No trust provision justified the disparity and no credible explanation was given. The court determined the conduct to be punitive and directed both removal and a surcharge for the monies wrongfully withheld.
How Removal Proceedings Work in California
A petition for the removal of a trustee shall be filed in the superior court of the county in which the trust is administered. The petitioner is typically a beneficiary or co-trustee and needs to allege specific grounds and support them with evidence. Courts can appoint a temporary trustee to preserve assets while the petition is pending. This is a significant remedy when ongoing misconduct endangers the estate.
Hackard Law litigates trustee removal cases throughout California. The process involves the collection of financial records, trust accountings, communications and witness testimony. Where substance abuse is alleged, we try to create a documented record that meets the evidentiary standard courts require. When the issue is undue influence, we look at the financial history of the trust to see the pattern of preferential treatment.
Discovery, forensic analysis, and the pursuit of justice – these are not just legal strategies, but safeguards for families threatened by undue influence and fraud. The California inheritance theft guide provides a broader framework for understanding how courts evaluate trustee misconduct alongside other forms of inheritance interference.

Why Acting Quickly Matters
For decades I have stood with families who waited too long to call. The financial cost increases with each month a compromised trustee stays in place. Assets of trust vanish. “Preferential transfers pile up. It becomes harder to reconstruct the records that would have supported a strong removal petition. The fracture in the family is often too deep for any judgment to heal.
If you believe a trustee is impaired, compromised by undue influence, or simply refusing to perform their duties, the time to act is now. A steadfast commitment to truth restores what dishonesty tried to steal – but only when families move before the damage becomes irreversible. Review the contingency fee guide for California trust litigation to understand your options before your first call.
Key Definitions
- Trustee removal: A court order terminating a trustee’s authority to administer a trust, available under California Probate Code section 15642 when grounds exist.
- Undue influence: Excessive pressure that overcomes the free will of a person, recognized in California as grounds for both invalidating trust amendments and removing trustees.
- Fiduciary duty: The legal obligation of a trustee to act in the best interests of all beneficiaries, with loyalty, prudence, and impartiality.
- Surcharge: A court-ordered remedy requiring a trustee to personally compensate the trust for losses caused by breach of fiduciary duty.
- Prudent investor standard: California’s requirement that trustees invest and manage trust assets as a prudent investor would, considering risk and return in the context of the trust’s purposes.
- Habitual substance abuse: A pattern of impairment from drugs or alcohol that renders a trustee unfit to perform their duties, recognized as grounds for removal under California law.
- Punitive refusal to distribute: A trustee’s withholding of distributions without legitimate trust-authorized justification, often treated as a breach of fiduciary duty.
- Temporary trustee: A court-appointed fiduciary who manages trust assets while a removal petition is pending, protecting beneficiaries from ongoing harm.
- Good cause: The legal standard under California Probate Code section 15642(b) that encompasses a range of trustee misconduct beyond the specifically enumerated grounds.
- Co-trustee: A person serving alongside another trustee, who may petition for removal of the other trustee when misconduct is present.
What to Do Next
- Look for patterns in the trust’s financial records – unexplained advances, rent-free occupancy, or distributions that favor one beneficiary over others.
- Get copies of all trust accountings and correspondence from the trustee as early as possible.
- Document any observations of impairment, erratic behavior, or statements that suggest the trustee is being influenced by a beneficiary.
- Try to avoid confronting the trustee directly before speaking with an attorney, as early confrontations can cause evidence to disappear.
- Look for any prior criminal history or financial judgments against the trustee that may be relevant to a removal petition.
- Get copies of the original trust document and any amendments, particularly those made after the settlor’s health declined.
- Try to avoid delay – the longer a compromised trustee remains in place, the greater the potential loss to the trust estate.
- Reach out to other beneficiaries who may share your concerns, as co-petitioners can strengthen a removal case.
