Heggstad Petitions in California: Establishing Trust Ownership of Disputed Property
Last updated October 9, 2026
The issue in brief
How a Heggstad petition under Probate Code section 850 asks a California court to declare an untitled asset trust property, who may oppose it, and what courts may order.
A Heggstad petition is a request, filed under California Probate Code section 850, asking the Superior Court to declare that a specific asset belongs to a trust even though title was never transferred into the trust's name. If granted, the asset is treated as trust property instead of passing through probate.
Most people facing a Heggstad question arrive at it after a death. A parent's trust lists the family house or a brokerage account, but the deed or the account statement still shows the parent's own name. The successor trustee now has to decide whether to go to court. A sibling or another heir may believe the asset was never meant to be in the trust at all. Either way, the question is no longer paperwork. It is a dispute about ownership. The answer decides who controls the property, which proceeding it moves through, and sometimes who ends up receiving it.
This page explains what the petition is and the situations that produce it. It covers the California statutes behind it, why the probate question matters, who may file and who may oppose, and what a court can order. It describes contested matters, not the routine creation or funding of a trust.
What a Heggstad Petition Is and What It Does
A Heggstad petition takes its name from the 1993 California Court of Appeal decision Heggstad v. Heggstad (1993) 16 Cal.App.4th 943. That decision is the origin of the doctrine. Its core idea is that a written declaration of trust that identifies specific property as trust property can establish the trust's ownership of that property, even without a separate deed or transfer document.
The doctrine connects to how California law says a trust can come into existence. Under Probate Code section 15200, one method is "a declaration by the owner of property that the owner holds the property as trustee." When a settlor signs a trust declaring that they hold a described asset as trustee, the petition asks the court to give that declaration effect. The settlor is the person who created the trust.
The petition itself is filed under Probate Code section 850. It asks the court to determine that the asset is trust property and to make an order reflecting that. It is heard by the Superior Court of California for the relevant county as a trust proceeding. It is not a full probate of the decedent's estate. Because it concerns what the trust holds, it sits alongside the court's authority over a trust's internal affairs, discussed in the next sections. The petition does not open a separate, court-supervised estate for the asset.
When a Heggstad Petition Arises: Common Scenarios
These disputes usually begin with a gap between what a trust document says and what the title records show. The patterns repeat:
- Real property. A home, a rental property or land appears on the trust's schedule of assets, or is described in the declaration, but no deed transferring it to the trustee was ever recorded.
- Bank and brokerage accounts. The settlor described an account in writing as a trust asset, but the institution's records were never retitled.
- Personal property and business interests. The trust instrument refers to valuables, a closely held company or an ownership interest, but there is no separate assignment document.
- Discovery after death. A successor trustee finds the gap only after the settlor dies. The trustee then needs a court order to administer the asset as trust property rather than leaving it to probate.
- A disputed intent. A beneficiary, an heir or someone claiming under a different document contends the asset was never intended to be trust property. They may argue it was sold, was meant for someone else, or passes by will or by intestacy. Intestacy means the statutory rules that apply when there is no will.
That last situation is the adversarial core of this area. The petition can be opposed. When it is, the court weighs evidence at a hearing, and the outcome depends on the documents and the proof. No one can say in advance that a petition will go unopposed or that it will be granted. Not every gap between a trust schedule and a title record leads to a dispute. When one does, though, it is a real lawsuit about property, with real consequences for the family members on each side.
The Legal Foundation: Probate Code § 850 and § 17200
Probate Code section 850 identifies who may ask the court to rule on a disputed asset and in what circumstances. For trusts, section 850(a)(3) allows "the trustee or any interested person" to petition in three situations:
- when the trustee is in possession of, or holds title to, property that is claimed to belong to another;
- when the trustee has a claim to property that someone else holds title to or possesses;
- when trust property is claimed to be subject to a creditor of the settlor.
A Heggstad petition usually fits the second situation. The trust claims an asset still titled in the decedent's name. Section 850(a)(2) separately lets the personal representative or any interested person petition about property the decedent held or claimed. The personal representative is the executor or administrator of a probate estate. Under section 850(b), the petition must set out the facts on which the claim is based.
Probate Code section 17200(a) generally allows a trustee or beneficiary to petition "concerning the internal affairs of the trust or to determine the existence of the trust." Section 17200(b) lists proceedings that count as internal affairs, and the statute says the list includes but is "not limited to" those it names. They include:
- determining questions of construction of the trust instrument;
- determining to whom property shall pass;
- settling the trustee's accounts;
- instructing the trustee;
- appointing or removing a trustee;
- compelling redress of a breach of trust by any available remedy.
A more detailed walk-through appears on the page about the Probate Code 17200 petition.
The court's power to act is broad. Under Probate Code section 856, if the court is satisfied that a transfer should be made, it orders the fiduciary or the person holding title or possession to convey or transfer the property to the person entitled to it, "or granting other appropriate relief." Section 856 has exceptions for section 853 and section 854. Under section 17206, the court in its discretion may make any orders necessary or proper to dispose of the matters presented. That includes appointing a temporary trustee. In practice, a granted order serves as the court's determination that the asset is trust property. That determination is what title holders and institutions rely on.
How much evidence is enough, and what kind, is decided on the facts in each case. Courts look at the language of the trust declaration and any schedule of assets. They also consider other evidence of the settlor's intent and the history of the asset. Without the specific documents, this page cannot say how a court would weigh any of them.
Why Avoiding Probate Matters in These Disputes
An asset that was not in the trust at the settlor's death may be subject to California probate. Probate is a court-supervised process, separate from trust administration, that is governed by the Probate Code. It is heard by the Superior Court of California for the relevant county, generally the county where the decedent was domiciled or where the property is located.
The practical stakes are control and route. During probate, the personal representative controls the estate's assets, not the trustee. If both a trust and a probate estate are open at the same time, and different people hold those roles, the same house or account can become the subject of competing claims. A successful section 850 petition can allow the asset to pass through the trust instead of through probate. That affects timing, cost and who directs the process.
That is why this question appears in disputes rather than in planning. Someone is already contending that an asset belongs in the trust, and someone else may be contending that it belongs in the estate or to them. It can be disorienting to learn that the house a parent clearly meant to leave through the trust may instead be headed into a separate court process. The petition is how a court resolves which path applies.
Who May File — and Who May Oppose — a § 850 Petition
The petitioner is usually the successor trustee. Section 850 also allows any interested person in the listed situations to file. A beneficiary of the trust is a common example.
Opposition can come from any interested person who disputes the claim. That may be an heir who would take the asset through probate, a beneficiary under a will or a different instrument, or a creditor. An opposing party files a written response. The court sets a hearing, and interested persons are given notice. If the facts are disputed, the hearing becomes an evidentiary contest. Each side presents evidence about the settlor's intent, the wording of the trust instrument and the asset's history. Where the challenge goes further and attacks the trust itself, it is a different proceeding, covered in the page on how to contest a trust.
Probate Code section 859 can enter these cases when property has been withheld. It applies if a court finds that a person has in bad faith wrongfully taken, concealed or disposed of property belonging to a trust or a decedent's estate. It also applies if the person took, concealed or disposed of the property by undue influence in bad faith or through elder or dependent adult financial abuse. On that finding, the person is liable for twice the value of the property recovered by an action under that part. The court may also, in its discretion, award reasonable attorney's fees and costs against that person. None of this is automatic. It turns on the court's finding, and the fee award is discretionary.
People on both sides of a Heggstad dispute often believe the other side is acting in bad faith. Sometimes the disagreement is simply a genuine dispute about what a parent intended. The statute gives each party a way to put its case to the court. It does not presume who is right.
What This Site Covers
This site covers disputes. That includes contested Heggstad petitions, section 850 proceedings in which a party opposes the petition, and related conflicts over whether a house, an account or a business belongs to a trust. Broader trust disputes, such as surcharge and trustee removal, are summarized on the page about California trust litigation.
This site is not the right resource for creating or amending a trust, for estate planning, or for trust drafting. It is also not the right resource for administering an estate or trust where no one disputes anything, or for a matter in another state.
Discussing a Dispute Over Trust Ownership of Property
Heggstad disputes turn on specifics. They depend on the exact wording of the trust declaration and any schedule, and on the deed or account records and their dates. They also depend on what happened to the asset in the settlor's last years, and on who has been holding or managing it since. A consultation about a contested section 850 matter would typically look at those documents, the timeline and the conduct of the people involved. An attorney who reviews them can explain which proceeding and remedies may apply. For a reader whose question is how to put property into a trust in the first place, this page is not the place to start.

Frequently asked questions
What is a Heggstad petition and when is it used?
A Heggstad petition is a petition under Probate Code section 850 asking a California Superior Court to declare that a specific asset belongs to a trust, even though title was never transferred to it. It is typically used after a settlor's death, when the trust instrument identifies the property but no deed or assignment was signed. Whether it is granted depends on the evidence.
What are the main reasons someone files a Heggstad petition instead of going through probate?
The main reason is that an asset left outside the trust may otherwise go through probate, a separate court-supervised process in the Superior Court of California for the relevant county. A successful petition can let the asset pass through the trust instead. That affects timing, cost and whether the trustee or a personal representative controls it.
Who can file a Heggstad petition in California?
Under Probate Code section 850, the trustee or any interested person may file in the situations the statute describes. Interested persons often include beneficiaries. An heir, a creditor or a beneficiary of a different instrument may oppose the petition in writing and contest it at the hearing.
Can a Heggstad petition be contested?
Yes. An interested person may file a written opposition, and the court then hears evidence about the settlor's intent, the trust's language and the asset's history. A contested petition is fully adversarial, and its outcome is not predetermined.
Who owns a home during probate?
During California probate, the personal representative controls the decedent's property under the supervision of the Superior Court of California for the relevant county. The trustee of any trust does not control it. That is why a contested section 850 petition matters: it determines whether a home is treated as trust property or as part of the probate estate.
What court hears a Heggstad petition in California?
The Superior Court of California for the relevant county hears these petitions. That is generally the county connected to the trust's administration or to the property. Local procedures vary, and the California Courts self-help pages describe probate court generally.
What happens if someone wrongfully withholds trust property in bad faith?
Under Probate Code section 859, a person may be liable for twice the value of the property recovered if the court finds one of the following: the person in bad faith wrongfully took, concealed or disposed of trust property; the person did so by undue influence in bad faith; or the person did so through elder or dependent adult financial abuse. The court may also, in its discretion, award reasonable attorney's fees and costs. Neither result is automatic.
Does a Heggstad petition resolve all disputes about what belongs in a trust?
No. A section 850 petition decides whether a particular asset belongs to the trust. It does not decide separate disputes, which are distinct proceedings. Those separate disputes include whether the trust itself is valid, whether a trustee breached a duty, and how trust assets are distributed.
