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.
