What Happened
Recent reporting on estate planning trends highlights a quiet crisis unfolding in American families: the majority of adults still have no plan in place for what happens to their assets after they die. According to a 2025 Trust & Will survey of 10,000 U.S. adults cited in recent coverage, roughly 55% of respondents reported having no estate plan at all, while only about 11% reported having a trust. A separate 2025 Caring.com and YouGov survey of more than 2,500 adults reported that only around 24% had a will and 13% had a living trust.
Those numbers matter because the absence of a well-drafted trust — or the existence of a vague, outdated, or unfunded one — is one of the leading drivers of trust litigation in California probate courts. When a trustor passes away and the trust document is unclear, when beneficiaries suspect undue influence, or when a trustee allegedly mishandles assets, families end up in contested proceedings that can drag on for years. This article walks through how those disputes arise, who may be legally responsible, and what Californians can do to protect their families from the same fate.
Who May Be Liable
Trust disputes in California typically involve several categories of potential defendants, depending on the facts. The trustee is often the first party scrutinized. A trustee who allegedly mismanages assets, fails to account to beneficiaries, self-deals, or distributes property in a way that conflicts with the trust terms could be liable for breach of fiduciary duty.
Individuals who allegedly exerted undue influence over the trustor — often a spouse, adult child, caregiver, or other person in a position of trust — may also face liability if a court finds that they pressured the trustor into amendments that did not reflect the trustor’s true wishes. In some cases, a drafting attorney or financial professional may be scrutinized if their work allegedly fell below the standard of care and caused measurable harm to beneficiaries. Finally, third parties who allegedly received trust property improperly may be ordered to return assets to the estate.
None of these parties should be assumed liable without a full investigation. California law requires proof, not suspicion.
Legal Theories That May Apply
Several legal theories commonly surface in California trust litigation:
- Breach of fiduciary duty. A trustee owes beneficiaries duties of loyalty, impartiality, and prudent administration. Alleged violations can support a claim for removal, surcharge, or damages.
- Lack of capacity. A trust or amendment may be invalidated if the trustor allegedly lacked the mental capacity to understand what they were signing, particularly if changes were made during serious illness.
- Undue influence. California Probate Code recognizes undue influence as a basis to invalidate testamentary documents when someone allegedly used excessive persuasion to overcome the trustor’s free will.
- Fraud or forgery. Allegations that a signature, amendment, or asset transfer was fabricated may support both civil and, in some cases, criminal exposure.
- Ambiguity and construction disputes. When trust language is unclear, beneficiaries may petition the court to interpret what the trustor intended.
- Financial elder abuse. Under California’s Welfare and Institutions Code, allegations that a vulnerable adult was financially exploited can carry enhanced remedies, including attorney’s fees.
- Failure to fund the trust. When assets were never retitled into the trust’s name, those assets may fall into probate — defeating the very purpose of the plan.
Damages Victims May Recover
Beneficiaries and successor trustees who prevail in California trust litigation may be entitled to a range of remedies, depending on the claim:
- Return of misappropriated assets to the trust or rightful beneficiaries.
- Surcharge against a trustee personally for losses caused by alleged breaches of duty.
- Removal of the trustee and appointment of a neutral successor.
- Double damages in certain cases involving bad-faith wrongful taking of estate property under California Probate Code section 859.
- Attorney’s fees and costs where authorized by statute, including certain financial elder abuse claims.
- Pre-judgment interest on improperly withheld distributions.
- Punitive damages in cases involving alleged fraud, malice, or oppression.
Every case is fact-specific, and the availability of each remedy depends on the evidence presented.
Evidence That Strengthens a Case
In our experience handling California trust disputes, the strongest cases are built on documentation that was created at or near the time key decisions were made. Useful evidence may include:
- The signed trust instrument and every amendment, along with prior versions showing how the plan evolved.
- Attorney notes, intake forms, and engagement letters that reflect the trustor’s stated intent and apparent capacity at signing.
- Medical records and physician evaluations near the time of signing or amendment, which may bear on capacity.
- Financial records showing account activity, transfers, beneficiary changes, and the trustee’s administration.
- Communications — emails, texts, letters — among family members, caregivers, and the trustor.
- Witness statements from neighbors, friends, clergy, or professionals who observed the trustor’s condition and relationships.
- Care facility records, visitor logs, and caregiver schedules in alleged undue influence cases.
- Any contemporaneous letter of explanation left by the trustor describing why beneficiaries were treated differently.
Preserving this evidence quickly matters. Records are discarded, memories fade, and witnesses move away.
What to Do Next
If you are a California beneficiary who suspects something is wrong with a trust administration — or a trustee facing accusations you believe are unfounded — the practical steps are similar:
- Request a copy of the trust. Under California Probate Code section 16061.7, trustees generally must notify beneficiaries and heirs after a trustor’s death. Beneficiaries typically have 120 days from receipt of that notice to contest the trust.
- Preserve every document. Do not throw away paperwork, delete emails, or discard medical records.
- Document your observations. Write down what you saw, when, and who else was present.
- Avoid informal admissions. Do not sign releases, waivers, or receipts without first understanding what rights you may be giving up.
- Act promptly. California statutes of limitations on trust-related claims can be short, and some run from the date of the trustee’s notice rather than the date of death.

Frequently Asked Questions
How long do I have to contest a trust in California?
In most cases, a beneficiary or heir has 120 days from the date the trustee serves formal notice under Probate Code section 16061.7 to file a contest. Missing that deadline can permanently bar a challenge, so it is critical to consult counsel as soon as you receive the notice. Other claims, such as breach of fiduciary duty, may have different limitations periods.
Can I sue a trustee who is also my sibling?
Yes. California law treats a trustee as a fiduciary regardless of their family relationship to beneficiaries. If a trustee allegedly breaches their duties — through self-dealing, failure to account, or improper distributions — any beneficiary may petition the probate court for relief, including removal and surcharge.
What if the trust was changed right before my parent died?
Last-minute amendments made during serious illness are a classic red flag and may support a claim of lack of capacity or undue influence. Courts look closely at the trustor’s medical condition, who arranged the changes, and whether the new terms benefit the person who facilitated them. These cases are fact-intensive and typically require medical records and witness testimony.
Does a California trust avoid probate completely?
A properly funded living trust generally avoids probate for the assets held inside it. However, any asset that was never retitled into the trust’s name may still require a probate proceeding. This is why trust funding — the process of actually transferring accounts and real estate into the trust — is just as important as the drafting itself.
What is undue influence under California law?
Under California Welfare and Institutions Code section 15610.70, undue influence means excessive persuasion that causes another person to act or refrain from acting by overcoming that person’s free will, resulting in inequity. Courts weigh the alleged victim’s vulnerability, the influencer’s apparent authority, the tactics used, and whether the outcome was unfair. Proving undue influence usually requires circumstantial evidence built from many sources.
Can I recover attorney’s fees if I win a trust case?
Sometimes. California generally follows the “American rule” where each side pays its own fees, but there are important exceptions. Successful financial elder abuse claims, actions that benefit the trust as a whole, and claims under Probate Code section 859 for bad-faith wrongful taking may allow a prevailing party to recover fees.
What should I do if I think a caregiver manipulated my relative?
Start by preserving every document, communication, and medical record you can find, and write down your own observations while they are fresh. Do not confront the caregiver directly, and avoid signing anything presented to you by the trustee until you speak with counsel. An attorney can evaluate whether financial elder abuse, undue influence, or related claims may apply.
Is mediation required before trust litigation in California?
Mediation is not always required by statute, but many California probate courts strongly encourage it, and some trust instruments include mandatory mediation clauses. Mediation can be a cost-effective way to resolve disputes privately before incurring the expense of discovery and trial. An experienced attorney can help you decide whether to pursue mediation early or preserve certain claims first.
