Constructive Trust in California: What It Is, When It Applies, and How to Pursue One

A constructive trust is an order a California court can make when someone holds property they got through fraud, accident, mistake, undue influence, a violation of a trust or another wrongful act. The court treats that person as an involuntary trustee and can order the property, or what it became, returned to the person who should have had it.

You may be reading this because a parent's house was deeded to someone else in the last months of life, because a trust account is far smaller than it should be, or because a sibling serving as trustee seems to be living on money meant for everyone. You may also be the trustee or relative now accused of holding property that belongs to someone else. Most people facing this process have never heard the term "constructive trust" until a dispute forces it on them. They want to know what the claim requires, which court hears it, what evidence matters and what deadlines could close the door. This guide walks through those questions in order, as California law describes them.

The guide is organized as six steps: identifying the property and the conduct, understanding the elements, choosing the proceeding, gathering evidence, understanding the remedy, and tracking deadlines. Each step describes how the law works. It does not tell any reader what to do in a particular case.

Before you start: what a constructive trust is and is not

A constructive trust is an equitable remedy. "Equitable" means a court has flexible power to make an order that prevents an unfair result, rather than only awarding money. No one drafts or signs a constructive trust. A court imposes it after finding that a person holds property they should not keep.

The statutory basis is California Civil Code section 2224. A person who gains a thing by fraud, accident, mistake, undue influence, the violation of a trust or another wrongful act is an "involuntary trustee" of that thing for the benefit of the person who would otherwise have had it, unless the holder has some other and better right to it. In plain words, the law treats the holder as keeping the property for someone else, whether or not the holder agreed to that role.

This is different from two other kinds of trusts:

• An express trust is the kind most families know. A settlor, the person who creates the trust, sets it up on purpose in a written document.
• A resulting trust is a court-recognized trust based on what the parties are presumed to have intended. A common example is when an express trust fails or is incomplete. It is covered briefly near the end of this guide.

A constructive trust does not create a new trust document. It is a court order that requires the person wrongfully holding specific property to transfer it. In California trust and estate disputes, the claim often comes up when an inheritance was diverted, when trust assets were taken by a trustee, or when real property was transferred through undue influence. Probate Code section 16420(a) also lists imposing a constructive trust among the remedies available when a trustee commits or threatens a breach of trust.

Step 1: Identify the property and the wrongful act

The first step is to identify two things clearly: the specific property involved, and the conduct that put it in someone else's hands.

The property. A constructive trust attaches to identifiable property, such as a house, a brokerage account, a business interest or a particular sum. It can also reach what that property was turned into, such as sale proceeds. It is not a general claim that someone owes money. If the property cannot be identified or followed, a court may turn to other remedies instead.

The wrongful act. Civil Code section 2224 names fraud, accident, mistake, undue influence, violation of a trust and "other wrongful act." The last phrase is broad. Claimants commonly rely on it for conduct such as breach of fiduciary duty. A fiduciary is a person, such as a trustee or executor, who must act for someone else's benefit. Undue influence has the meaning Probate Code section 86 gives it, which refers to the Welfare and Institutions Code definition and supplements the common-law meaning.

Common fact patterns in trust and estate disputes include:

• A trustee using trust assets for personal benefit. Probate Code section 16004(a) says a trustee may not use or deal with trust property for the trustee's own profit or for any purpose unconnected with the trust, and may not take part in a transaction in which the trustee has an interest adverse to the beneficiary. Under section 16004(c), a transaction between the trustee and a beneficiary in which the trustee obtains an advantage from the beneficiary is presumed to violate the trustee's fiduciary duties. That presumption affects the burden of proof. It does not apply to an agreement about hiring or paying the trustee.
• A transfer to a drafter, transcriber or caregiver. Under Probate Code section 21380, a provision of an instrument making a donative transfer, meaning a gift, to certain people is presumed to be the product of fraud or undue influence. Those people include the person who drafted the instrument; a person in a fiduciary relationship with the transferor who transcribed it or caused it to be transcribed; and a care custodian of a dependent adult, if the instrument was signed while the care custodian provided services or within 90 days before or after that period. The section also covers some relatives, cohabitants, employees and law-firm associates of those people. The presumption affects the burden of proof. The recipient may rebut it with clear and convincing evidence, except that it is conclusive for a transfer to the drafter and to persons the statute associates 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 or relative falls under this presumption. Only the categories the statute names do.
• Property taken or hidden from an estate or trust. Probate Code section 859 provides a separate remedy, discussed in Step 5, for property wrongfully taken, concealed or disposed of in bad faith.

A person considering a claim usually begins by writing down what the property is, who holds it now, and what act or omission caused the transfer, with dates.

Step 2: Understand the elements a court requires

California courts generally look for three things before imposing a constructive trust:

1. A res. This is specific, identifiable property.
2. The claimant's right to it. The person asking for the property must show they would otherwise have had it.
3. Wrongful acquisition or unjust enrichment. The holder must have gotten or kept the property through conduct of the kind section 2224 describes, so that it would be unfair to let them keep it.

The claimant generally carries the burden of proving the wrongful act and the link between that act and the specific property. "Burden of proof" means the side that must persuade the court. A statutory presumption can shift that burden. Under section 21380, for example, the recipient of a covered transfer must rebut the presumption with clear and convincing evidence.

Tracing is often the hardest part. If the original property was sold, exchanged or mixed with other money, the claimant must follow it into its current form, such as a new account, a different house or a vehicle. How far a court can follow it depends on what the records show. No single element is enough by itself, and courts weigh the evidence as a whole.

In a breach-of-trust case, a constructive trust is one option among several. Section 16420(a) lets the claimant seek the remedies that fit the facts, and section 16420(b) says those remedies do not rule out any other remedy available by statute or common law.

For a person accused of wrongdoing, these same elements frame the defense. Questions about whether the property can be identified, whether the claimant had a right to it, and whether the holder had "some other and better right," as section 2224 puts it, are often central to the case.

Step 3: Determine where and how to file in California

Trust and estate cases in a county are heard by the Superior Court of California for that county. Within that court, a constructive trust claim can take more than one procedural form, depending on how the dispute arose.

Inside an existing trust. Under Probate Code section 17200(a), a trustee or beneficiary may petition the court about the internal affairs of the trust or to determine whether a trust exists, except as section 15800 provides. Section 17200(b) lists types of proceedings, including settling accounts, passing on the trustee's acts, instructing the trustee, compelling information or an account, and appointing or removing a trustee. That list is not exhaustive. A Probate Code 17200 petition is a common way to bring a constructive trust request against a trustee. Under section 17206, the court may make any orders necessary or proper to dispose of the matters raised, including appointing a temporary trustee.

Breach of trust specifically. If a trustee commits or threatens a breach of trust, a beneficiary or cotrustee may start a proceeding under section 16420(a) for the remedies listed there, including a constructive trust.

Inside a probate estate. When a decedent's estate is being probated, a constructive trust claim may be raised within the estate proceeding or as a separate civil action, depending on the facts. Probate Code section 850 allows a personal representative or interested person to petition about property in the situations that section lists. Section 859 refers to actions brought under that part.

No pending proceeding. Where no trust or probate case is open, a constructive trust claim under Civil Code section 2224 may be brought in an ordinary civil action in the Superior Court.

Each route has its own pleading requirements and notice rules. An attorney who reviews the documents can explain which route applies to a particular dispute.

Step 4: Gather and preserve evidence

This step is often the most painful one, because the evidence usually involves family records, a loved one's final months and people you know well. The categories are still fairly predictable.

• Proof of entitlement. This includes trust instruments and amendments, wills, deeds, account statements and correspondence showing who was meant to receive the property.
• Proof of the wrongful act. This includes communications that suggest fraud or pressure, and records of transactions a trustee was barred from making under section 16004(a), such as transfers to the trustee or payments for the trustee's personal expenses.
• Tracing records. This includes bank and brokerage statements, title documents, escrow files and anything else connecting the original property to what the holder has now.
• Section 21380 facts. These include dates of care, the caregiver's relationship to the transferor, and who drafted or transcribed the instrument.

Beneficiaries often lack the records they need at first. A trustee has a duty to keep beneficiaries reasonably informed of the trust and its administration (Probate Code section 16060). Except as section 16069 provides, the trustee must also report requested information relevant to a beneficiary's interest on reasonable request (section 16061). If the trustee has not provided requested information within 60 days after a reasonable written request, and the beneficiary has not received it within the six months before the request, the beneficiary may petition to compel it under section 17200(b)(7). A similar rule applies to compelling an account.

Emails, texts, voicemails and electronic files can disappear. Keeping copies protects evidence that both sides may need later.

Step 5: Understand the remedy and what a court can order

When a court imposes a constructive trust, it declares the holder an involuntary trustee and may order the specific property, or its traceable proceeds, transferred to the person entitled to it. That reflects section 2224, under which the holder keeps the thing for the benefit of the person who would otherwise have had it.

In breach-of-trust proceedings, section 16420(a) lists these remedies:

• compelling the trustee to perform the trustee's duties
• enjoining a breach of trust
• compelling the trustee to redress a breach by payment of money or otherwise
• appointing a receiver or temporary trustee
• removing the trustee
• subject to section 18100, setting aside the trustee's acts
• reducing or denying the trustee's compensation
• subject to section 18100, imposing an equitable lien or a constructive trust
• subject to section 18100, tracing and recovering wrongfully disposed property

Section 16420(b) keeps other statutory and common-law remedies available. Questions about removal often arise alongside constructive trust claims. Those questions, and the broader picture, are covered in the guide to California trust litigation.

Surcharge. A surcharge is a money charge against a trustee. Under section 16440(a), a trustee who commits a breach of trust is chargeable with whichever of these is appropriate under the circumstances:

• any loss or depreciation in value resulting from the breach, with interest
• any profit the trustee made through the breach, with interest
• any profit that would have accrued to the trust estate

Surcharge is not automatic. Under section 16440(b), the court may excuse a trustee who acted reasonably and in good faith under the circumstances as the trustee knew them, in whole or in part, if that would be equitable.

Double value under 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 through 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 by an action under that part. In the court's discretion, the person may also be liable for reasonable attorney's fees and costs. Without the required finding, this remedy does not apply.

Equitable lien. An equitable lien is related to a constructive trust but works differently. It secures a money claim against specific property instead of ordering the property transferred. Depending on the facts, either remedy, or both, may be requested.

Step 6: Watch the applicable deadlines

California law sets different deadlines for different claims. No single deadline applies to every situation.

Breach of trust (Probate Code section 16460(a)). A claim is barred unless a proceeding begins within three years after the beneficiary receives an interim or final account, or other written report, that adequately discloses the claim. If no account or report adequately discloses it, or none is received, the three years run from when the beneficiary discovered, or reasonably should have discovered, the subject of the claim.

Trust contests (sections 16061.7 and 16061.8). A trustee must serve a notification in the events section 16061.7(a) lists. Those events include when a revocable trust becomes irrevocable because of a settlor's death and whenever the trustee of an irrevocable trust changes; the list is longer than these two. A person served with the notification under section 16061.7(a)(1) cannot bring an action to contest the trust more than 120 days after the date the notification is served, or 60 days after the date a copy of the trust terms is delivered to that person during that 120-day period, whichever is later. The guide on how to contest a trust covers that process.

Revoking the probate of a will (section 8270). Within 120 days after a will is admitted to probate, an interested person may petition to revoke the probate. This option is not available to a party to a will contest or to a person who had actual notice of a contest in time to join it. A person who was a minor, or who was incompetent and had no guardian or conservator, when the will was admitted may petition at any time before an order for final distribution.

Civil actions under section 2224. Claims brought outside probate are governed by the general civil limitations rules for the underlying wrong. A discovery rule, which starts the clock when the claimant learned or should have learned of the wrong, may apply.

Constructive trust vs. resulting trust: a brief distinction

A resulting trust is based on the parties' presumed intent. It can arise when an express trust fails or is incomplete, or when one person pays for property titled in another person's name without intending a gift. A constructive trust does not depend on intent. A court imposes it because property was obtained through fraud, undue influence, breach of fiduciary duty or another wrongful act under section 2224.

The difference affects the evidence. A resulting trust claim depends on proof of what the parties intended when the transaction happened. A constructive trust claim depends on proof of wrongful conduct. Both are court-imposed equitable remedies, neither comes from a written instrument, and both may be pleaded in the alternative when the facts could support either theory.

Typical timeline

How long a case takes depends on the proceeding, whether the other side files objections, how much discovery is needed and how long tracing takes. No standard duration applies. The fixed time markers that do exist come from statute: the 60-day and six-month conditions for petitions to compel information or an account, the 120-day and 60-day trust contest periods, the 120-day period under section 8270, and the three-year breach-of-trust periods under section 16460(a). In a case with urgent concerns, a request for a temporary trustee under section 17206 may be made before the case is resolved.

When the process gets complicated

The property has already been sold

Tracing follows the property into its proceeds. If the proceeds were spent or mixed with other money beyond what the records can follow, the claim may shift toward money remedies such as surcharge under section 16440(a).

The trustee resigns or is removed mid-case

A change of trustee does not erase claims for past conduct. For an irrevocable trust, a change of trustee is also one of the events that requires a new trustee notification under section 16061.7(a).

A no contest clause is in the trust

A no contest clause may be enforced only against the contests the Probate Code describes. One is a direct contest brought without probable cause. If the clause expressly says so, it may also apply to a challenge to a transfer on the ground that the property was not the transferor's, or to a creditor's claim. Probable cause exists if the facts known when the contestant files would lead a reasonable person to believe there is a reasonable likelihood the requested relief will be granted after further investigation or discovery. A no contest clause does not automatically disinherit everyone who challenges a trust.

A trust case and a probate case run in parallel

When assets sit in both a trust and a probate estate, related claims may proceed in more than one matter in the same Superior Court. The procedural route for each piece can differ.

Talking through a constructive trust claim

Constructive trust claims depend on details: which property, what records trace it, what conduct moved it, and which deadline governs the dispute. A consultation is a chance to go through the trust or will, the deeds and account statements, any trustee notification or account you received, and the dates when the transfers happened. A reader who is still unsure whether a dispute exists at all may first want to make a written request for information from the trustee.
