Dispute Over Estate Property in California
Last updated October 9, 2026
The issue in brief
How California estate property disputes work: 17200 and 850 petitions, trustee removal and surcharge, the 120-day/60-day contest rule and section 859 recovery.
A dispute over estate property in California is a court fight over who owns or controls what a person left behind: a house, accounts, a business or personal belongings. It is resolved in the Superior Court for the relevant county, through a petition in a probate case or a petition about a trust, with deadlines that depend on the document involved.
Most people facing this kind of dispute did not go looking for it. A parent has died, and a sibling now holds the keys to the house, controls the bank accounts, and answers questions with silence or irritation. Or a trust was amended in the last months of a parent's life, and the new version leaves the family's largest asset to one person. Sometimes the reader is the trustee or executor, accused of taking what was never theirs and unsure what the law actually requires of them. The questions underneath are usually the same: what the other side is allowed to do, what can be done about it, and how much time there is.
This page explains how California law treats these disputes: the claims, the duties, the remedies, the deadlines, and how the court process works. It is written for people in a real or imminent disagreement, not for people planning an estate.
What a Dispute Over Estate Property Involves in California
Estate property disputes arise in two main settings, and which one applies shapes everything that follows. The first is a probate estate: property that passes under a will, or without one, and is administered through the Superior Court of California for the county where the decedent lived, with a court-appointed personal representative (the executor or administrator) in charge. The second is a trust, which is usually administered privately by a trustee with no court involvement at all until someone files a petition.
That difference matters to a family member who believes property has been mishandled, concealed or wrongfully transferred. If the house sits in a probate estate, the dispute runs through the open probate case and the personal representative answers to the court. If the house is held in a trust, nothing reaches a judge until a trustee or beneficiary asks. Probate Code section 17200 is the main door: a trustee or beneficiary of a trust may petition the court about the internal affairs of the trust or to determine whether a trust exists at all, with a limited exception under section 15800. The Probate Code 17200 petition is the vehicle for most trust disputes.
A third path applies when the fight is over title, meaning whether a particular asset belongs to the estate or trust at all. Probate Code section 850 authorizes petitions asking the court to order property conveyed or transferred, and under section 856, if the court is satisfied a conveyance or transfer should be made, it orders the fiduciary, or the person holding title or possession, to make it, or grants other appropriate relief. In a probate estate, section 11600 also lets the personal representative or an interested person petition for preliminary or final distribution to the persons entitled to it, which becomes relevant when an executor simply sits on the estate.
Every one of these proceedings is heard by the Superior Court of California for the relevant county. Courthouse assignments and local procedures vary by county and are not addressed here.
Common Grounds for Disputing Estate Property
Testamentary capacity, the mental ability required to make a valid will, is tested at the moment the will is signed. Under Probate Code section 6100.5, a person lacks capacity if at that time they could not understand the nature of making a will, could not understand and recollect the nature and situation of their property, or could not remember and understand their relations to living descendants, spouse and parents and to those whose interests the will affects. A person also lacks capacity if a mental health disorder with symptoms including delusions or hallucinations caused them to leave property in a way they otherwise would not have. A diagnosis such as dementia does not, on its own, make a will invalid; the question is what the person could understand on the day they signed.
Undue influence is a separate theory. Probate Code section 86 gives the term the meaning a section of the Welfare and Institutions Code assigns it, and supplements rather than replaces the common law. In practice, undue influence claims tend to focus on late-life amendments, isolation from family, and a beneficiary who was closely involved in creating the document.
Some transfers start with a presumption against them. Under Probate Code section 21380, a provision making a gift to the person who drafted the instrument, to a person in a fiduciary relationship with the transferor who transcribed it or caused it to be transcribed, or to a care custodian of a dependent adult, if the instrument was signed while the care custodian was providing services or within 90 days before or after that period, is presumed to be the product of fraud or undue influence. That presumption shifts the burden of proof and can generally be rebutted by clear and convincing evidence, but it is conclusive for a gift to the drafter and to certain people associated with the drafter. A beneficiary who fails to rebut it bears all costs of the proceeding, including reasonable attorney's fees. Not every gift to a caregiver, relative or helper is presumed invalid; the presumption reaches only the people and circumstances the statute describes.
No contest clauses, provisions that penalize a beneficiary who challenges the document, worry many readers more than they should. Under Probate Code section 21311, such a clause may be enforced only against a direct contest brought without probable cause and, only if the clause expressly says so, against a pleading challenging a transfer on the ground the property was not the transferor's, or against a creditor's claim. Probable cause exists if, when the contest is filed, the facts known to the contestant would cause a reasonable person to believe there is a reasonable likelihood the relief requested will be granted after further investigation or discovery. A no contest clause does not automatically disinherit everyone who challenges a trust or will.
Wrongful taking is the last common ground. Under Probate Code section 859, if a court finds that a person in bad faith wrongfully took, concealed or disposed of property belonging to a trust or a decedent's estate, or took, concealed or disposed of it by undue influence in bad faith or through elder or dependent adult financial abuse, that person is liable for twice the value of the property recovered in the action, and the court may, in its discretion, also award reasonable attorney's fees and costs against them. Neither the doubled amount nor the fees follow automatically; the court has to make the finding first.
Trustee Duties and What Happens When They Are Breached
A trustee owes the beneficiaries duties set out in the Probate Code, and many trust disputes come down to which duty was or was not kept. For a trustee reading this, the same rules describe what the law expects and where the line sits.
Self-dealing. Probate Code section 16004(a) bars a trustee from using or dealing with trust property for the trustee's own profit or for any purpose unconnected with the trust, and from taking part in any transaction in which the trustee has an interest adverse to the beneficiary. Under section 16004(c), a transaction between trustee and beneficiary, during the trust or while the trustee's influence remains, by which the trustee gains an advantage from the beneficiary is presumed to violate the trustee's duties. That presumption affects the burden of proof and does not apply to an agreement about the trustee's hiring or compensation. A trustee who moves into the family home rent-free, or buys a trust asset at a discount, is the classic setting.
Information. Section 16060 requires the trustee to keep beneficiaries reasonably informed of the trust and its administration. The trustee must also, with limited exceptions, report requested information relevant to a beneficiary's interest on reasonable request.
Accounting. Under section 16062, the trustee generally must account at least annually, at termination of the trust, and on a change of trustee, to each beneficiary to whom income or principal is required or authorized in the trustee's discretion to be currently distributed. The section has exceptions, including for certain trusts created before July 1, 1987, and not every beneficiary is owed an annual account. Even where the trust instrument or a beneficiary's writing waives the account, the court may compel one on a showing that a material breach of trust has reasonably likely occurred.
When requests go unanswered, section 17200 provides two specific petitions. A beneficiary may petition to compel information if the trustee has not provided it within 60 days after a reasonable written request and the beneficiary has not received it within the six months before the request. A beneficiary may petition to compel an account if the trustee has not submitted a requested account within 60 days after written request and no account was made within the six months before the request.
Remedies for breach. If a trustee commits or threatens to commit a breach of trust, Probate Code section 16420 lets a beneficiary or cotrustee bring a proceeding for purposes including compelling the trustee to perform, enjoining the breach, compelling redress by payment of money or otherwise, appointing a receiver or temporary trustee, removing the trustee, setting aside the trustee's acts (subject to section 18100), reducing or denying compensation, and imposing an equitable lien or constructive trust (a court order treating property as held for the rightful owner), also subject to section 18100. California law also allows tracing and recovering wrongfully disposed property, and these remedies do not rule out any other appropriate remedy.
Surcharge. A surcharge is a money judgment against the trustee personally. Under Probate Code section 16440(a), a trustee who breaches the trust is chargeable with whichever of these is appropriate: the loss or depreciation in value resulting from the breach, with interest; any profit the trustee made through the breach, with interest; or any profit that would have accrued to the trust but for the breach. Under section 16440(b), the court may excuse a trustee in whole or in part if the trustee acted reasonably and in good faith under the circumstances as known to the trustee and excusing them would be equitable. Surcharge is never automatic.
Removal. Under Probate Code section 15642(a), a trustee may be removed in accordance with the trust instrument, by the court on its own motion, or on petition of a settlor, cotrustee or beneficiary under section 17200. The grounds include a breach of trust, insolvency or unfitness, hostility or lack of cooperation among cotrustees that impairs administration, the trustee failing or declining to act, and excessive compensation.
Compensation. If the trust instrument does not set the trustee's pay, section 15681 entitles the trustee to reasonable compensation under the circumstances. A trustee generally may not charge an increased fee without first giving the beneficiaries at least 60 days' written notice, and a section 17200 petition served before that period ends holds the increase back until the court orders otherwise or the petition is dismissed.
Not every disagreement with a trustee is a breach. A trustee who sells a house the beneficiaries wanted to keep, or who moves slower than the family would like, may be acting within the trust's terms. The duties above are the measure.
Will Contests and Probate Estate Disputes
A will contest filed before the will is admitted to probate begins with an objection. Under Probate Code section 8250, the contestant files an objection to probate of the will; a summons is then issued and served, with the objection, on the persons entitled to notice of the hearing, and those served must file a written response within 30 days after service. A person named as executor has no duty to defend the contest until appointed personal representative.
After admission, a narrower window applies. Under Probate Code section 8270, within 120 days after a will is admitted to probate, an interested person may petition to revoke the probate of the will, with written grounds of opposition. That petition is not available to a party to a will contest or to a person who had actual notice of one in time to join it. A person who was a minor, or incompetent without a guardian or conservator, when the will was admitted may petition at any time before the order for final distribution.
These will deadlines are separate from the trust contest deadline described below. A family whose parent left both a will and a trust may face two different clocks.
Executors can also be removed. Probate Code section 8502 lists the causes: the personal representative has wasted, embezzled, mismanaged or committed a fraud on the estate, or is about to; is incapable of properly performing the duties or is not qualified; has wrongfully neglected the estate or long neglected to act; removal is otherwise necessary to protect the estate or interested persons; or any other cause provided by statute. For heirs watching an estate stall for months while property deteriorates, neglect and mismanagement are the grounds that tend to come up.
Trust Contest Deadlines Under California Law
Probate Code section 16061.8 sets the clock for contesting a trust after notice. A person served with the trustee's notification under section 16061.7(a)(1) cannot bring an action to contest the trust more than 120 days from the date the notification is served on them, or 60 days from the date a copy of the trust's terms is delivered to them during that 120-day period, whichever is later. The first branch is triggered by service of the notification; the second by delivery of the trust terms, if requested and delivered inside the 120 days.
The trustee's notification is itself required by section 16061.7(a) in several events, including when a revocable trust becomes irrevocable because of a settlor's death and whenever the trustee of an irrevocable trust changes. The period does not run from the date of death or from the date the trust became irrevocable, and not every trust contest is governed by the 120-day limit; the deadline is tied to the notification. A beneficiary who has just received an envelope from a trustee's lawyer is often looking at the start of this clock. More on the mechanics appears in the page on how to contest a trust.
Breach of trust claims run on a different clock, and this is what people usually mean by the "three-year rule" for an estate. Under Probate Code section 16460, if a beneficiary receives an interim or final account or other written report that adequately discloses the existence of a claim against the trustee, the claim is barred unless a proceeding is commenced within three years after receiving it. A report adequately discloses a claim if it gives enough information that the beneficiary knows of the claim or reasonably should have inquired. Where no such account or report discloses the claim, or none is received, the three years generally runs from when the beneficiary discovered, or reasonably should have discovered, the subject of the claim.
How California Courts Resolve Estate Property Disputes
A section 17200 petition is a written request filed in the Superior Court asking the judge to decide a specific question about a trust. The statute lists proceedings including construing the trust instrument, determining the existence of any immunity, power, privilege, duty or right, determining the validity of a trust provision, and ascertaining beneficiaries and to whom property passes on termination, and that list is not exhaustive.
Under Probate Code section 17206, the court may make any orders and take any other action necessary or proper to dispose of the matters the petition presents, including appointing a temporary trustee to administer the trust in whole or in part. That breadth is significant when a beneficiary believes assets are at risk while the dispute is pending.
The orders a court may make range widely: compelling an accounting, compelling distribution, removing and replacing a trustee or executor, surcharging a fiduciary, setting aside a transfer, imposing a constructive trust, or, under section 859, awarding double the value of property recovered after the required finding. Each is a possibility the court weighs on evidence; none is a predictable result, and each side's account is tested in the same proceeding. The California trust litigation attorney page discusses these remedies in a broader context.
Evidence in these cases is usually documentary: the trust and every amendment, the will, bank and brokerage statements, deeds, the trustee's accounts, medical records bearing on capacity, and communications between the decedent and the people around them in the final years.

Discussing Your Estate Property Dispute
Estate property disputes turn on details that a general page cannot reach: which document controls the asset, whether and when a trustee's notification was served, what the accounts disclosed, and what happened in the months before a signature. A consultation about a dispute like this typically looks at the trust or will and any amendments, the dates of death, notification and delivery of trust terms, the accounts or reports received, deeds and account statements, and the specific conduct at issue. Readers still deciding whether they have a dispute at all, rather than a question about planning or routine administration, may find this page answers more than a call would.
To discuss a dispute like this with an attorney, you may request a consultation about your dispute through California Trust Litigation Lawyers.

Frequently asked questions
What kind of attorney handles estate property disputes in California?
Trust and probate litigation attorneys handle these disputes. They bring or defend petitions in the Superior Court of California under the Probate Code, such as petitions to compel an accounting, remove a trustee or executor, contest a will or trust, or recover property under sections 850 and 859.
How do you deal with a difficult beneficiary or co-heir in a California estate?
The Probate Code gives each side defined tools. A trustee facing conflicting demands may petition under section 17200 for instructions, including a ruling on a power or duty. A beneficiary who believes the trustee is acting improperly may petition for information, an account or removal. The court decides on the evidence, not on either party's account.
What is the most common source of inheritance disputes?
Recurring grounds include undue influence, lack of testamentary capacity under section 6100.5, gifts presumed invalid under section 21380, trustee self-dealing under section 16004, and failures to inform or account under sections 16060 and 16062. Many disputes involve more than one of these at once.
What is the three-year rule for a deceased person's estate in California?
It usually refers to the three-year limit on breach of trust claims in Probate Code section 16460. The claim is barred unless filed within three years after receiving an account or written report that adequately discloses it, or, where none discloses it, generally within three years after the beneficiary discovered or reasonably should have discovered it. This is separate from the trust contest deadline.
Can a no-contest clause prevent a beneficiary from disputing a California trust or will?
Only in limited situations. Under section 21311, a no contest clause may be enforced against a direct contest brought without probable cause and, if the clause expressly says so, against a challenge claiming the property was not the transferor's or a creditor's claim. A contest brought with probable cause is not penalized.
How long does a beneficiary have to contest a trust in California?
A person served with the trustee's notification under section 16061.7(a)(1) has until the later of 120 days from service of that notification, or 60 days from delivery of a copy of the trust terms if delivered during the 120 days (section 16061.8). The period does not run from the date of death.
Can a trustee be removed for mismanaging estate property in California?
Yes, if the court finds grounds. Under section 15642, removal may occur under the trust instrument, on the court's own motion, or on petition of a settlor, cotrustee or beneficiary, on grounds including breach of trust, unfitness, cotrustee hostility impairing administration, failing to act and excessive compensation. Removal is not automatic.
What happens if someone wrongfully takes property from a California estate?
The property can be pursued through a petition under section 850, and the court may order it transferred to the person entitled to it under section 856. If the court also finds a bad-faith wrongful taking, concealment or disposition, a bad-faith taking by undue influence, or elder or dependent adult financial abuse, section 859 makes the person liable for twice the value recovered, with fees and costs in the court's discretion.
