When a trust dispute arises, you need attorneys who understand how California trusts are drafted, administered, and litigated.

Our team brings over 200 years of combined legal experience, and we represent both trustees and beneficiaries through every stage of a dispute.

If you’re facing a trust dispute in Pleasanton or the surrounding East Bay, we’re ready to talk with you. Call (510) 344-2599 to speak with our team.

Trust Disputes We Handle

Trust conflicts can take many forms. We handle a full range of situations that bring trustees and beneficiaries into conflict.

The types of matters we handle include:

• Trustee misconduct: Failure to follow trust instructions, make timely distributions, avoid co-mingling personal and trust funds, refrain from self-dealing or using trust assets for personal benefit, or treat beneficiaries evenhandedly
• Trust contests: Challenges to the validity of a trust document based on lack of capacity, undue influence, fraud, or improper execution
• Beneficiary disputes: Conflicts arising from ambiguous or outdated trust language, disagreements over asset valuation, or competing interpretations of the settlor’s intent
• Trustee removal proceedings: Petitions filed in Alameda County Superior Court when a trustee can’t or won’t fulfill fiduciary duties under the California Probate Code
• Complex asset disputes: Trust matters involving real estate holdings or business interests that require both litigation and transactional analysis
• Trust modification petitions: Court petitions to modify irrevocable trusts where changed circumstances would defeat the trust’s original purpose or where beneficiary consent supports a change

California Probate Code sections 15400 through 15414 govern when and how trusts can be modified or terminated. A revocable trust can be amended by the settlor while living; disputes over those amendments most often surface after the settlor’s incapacity or death. Irrevocable trusts generally require court approval to modify, with petitions filed in the probate division of Alameda County Superior Court. In some matters, when all beneficiaries unanimously consent and the change doesn’t conflict with a material purpose of the trust, a modification may be accomplished without court involvement.

Trust modification is a forward-looking remedy. It’s distinct from litigation over past trustee conduct or document validity, though both paths can be pursued in the same proceeding when the facts support it.

Why Pleasanton Clients Choose Randick O'Dea Tooliatos Vermont and Sargent for Trust Litigation

Hannah Sargent, the firm’s trust, probate, and estate planning attorney, is an East Bay native who practices from our Pleasanton and Castro Valley offices. She earned her JD from UC Berkeley School of Law, where she received the Prosser Prize for finishing second in her class. She also holds an advanced law degree from Georgetown University Law Center and is a VA-certified attorney. Her memberships include the East Bay Trust and Estate Lawyers association and the East Alameda County Bar Association.

That background in trust administration matters in litigation. When we review a disputed trust document, we’re reading it the same way we would have drafted it, which sharpens how we identify the provisions in dispute and build case strategy around them. The firm has earned Super Lawyers recognition and a Martindale-Hubbell Preeminent rating, both reflecting peer assessment of legal ability and ethical standards.

Trust disputes that involve business interests or tax implications don’t require you to hire additional counsel. Our in-house attorneys handling business law and tax planning collaborate directly with the litigation team, so those issues are addressed as part of a unified strategy rather than handed off.

How We Approach Trust Litigation

We begin with a direct assessment of the dispute: what the trust document says, what conduct is alleged, and what remedies are available under the California Probate Code. When financial records, fiduciary accountings, or asset valuations are central to the case, we work with accountants and appraisers to build a factual foundation the court can rely on.

Many trust disputes resolve through mediation or negotiated settlement, which can reduce cost and avoid the strain of a full trial on family relationships. We pursue negotiation, mediation, and arbitration as resolution paths whenever they serve our clients’ interests. When a matter requires courtroom representation in Alameda County Superior Court, we’re prepared to take it there. Our clients are kept informed at every stage, from initial strategy through resolution.

Frequently Asked Questions

What Is the Difference Between Trust Litigation & Estate Litigation?

Trust litigation focuses on disputes involving the trust document, the trustee’s conduct, or the rights of beneficiaries under a trust. Estate litigation more broadly covers will contests, executor conduct, and distribution of probate assets. The two can overlap, particularly when a decedent held assets in both a trust and a probate estate, but the legal standards and court procedures differ.

Can a Beneficiary Remove a Trustee in California?

A beneficiary may petition the probate court to remove a trustee who has breached fiduciary duties, become substantially unable to manage the trust’s financial resources, or is otherwise unfit to administer the trust. The court applies standards set by the California Probate Code and considers the interests of all beneficiaries, not just the petitioning party.

Do I Need an Attorney Even If the Trust Seems Straightforward?

Trust disputes often turn on fiduciary accounting, document interpretation, and procedural requirements that aren’t obvious from the face of the trust. Legal guidance can be valuable even when the underlying facts appear simple, and early involvement can give you more options than waiting until a dispute escalates.

How Long Does Trust Litigation Take in Alameda County?

Duration depends on the complexity of the dispute, the number of parties involved, and the court’s calendar. Matters resolved through mediation or negotiated settlement can typically conclude faster than full trials. We can give you a realistic assessment of timing during your initial consultation.
