When a family learns that a house, account, or other asset was supposed to be in the trust but was never formally transferred, the question becomes urgent fast: section 850 versus full probate. That choice can affect how long administration takes, how much it costs, and whether a sale, distribution, or refinance can move forward without months of delay.
In California, these two paths are not interchangeable. A Probate Code Section 850 petition, often called a Heggstad petition, is a targeted court procedure used to confirm that an asset belongs to a trust when the trust creator clearly intended that result but title was never completed correctly. Full probate is the broader court-supervised administration of a decedent’s estate when assets are still owned in the decedent’s individual name and no simpler path applies.
For successor trustees and families, the difference matters because the wrong assumption can waste time. Some assets can be brought into the trust through a Section 850 petition and administered under the trust. Others truly require probate. The key issue is not what everyone hoped would happen. It is whether the documents and surrounding facts support trust ownership strongly enough for the court to confirm it.
How section 850 versus full probate differs
A Section 850 petition is usually narrower, faster, and less expensive than full probate because it asks the court to decide a specific ownership issue. The petition typically argues that the asset should be treated as trust property based on the trust instrument, schedules of assets, assignment language, prior deeds, or other evidence showing intent to hold the asset in the trust.
Full probate is different in both scope and procedure. It opens a formal estate administration, often requiring appointment of a personal representative, notice to heirs and creditors, inventory and appraisal, possible bond issues, and court oversight before assets can be distributed. That process may be necessary, but it is a much larger proceeding than asking the court to confirm trust ownership of a particular asset.
This is why Section 850 matters so much in trust administration. If a trust creator signed a trust and identified the property as a trust asset, but a deed was never recorded or an account stayed titled individually, a focused petition may solve the problem. If the evidence of intent is thin, contradictory, or missing, probate may still be the required path.
When a Section 850 petition may work
The classic Heggstad scenario involves a revocable living trust that specifically lists an asset on a schedule attached to the trust, or otherwise clearly identifies it as trust property, but title was never updated. California courts have long recognized that in the right case, that can be enough to confirm trust ownership.
Real estate is where this issue often becomes urgent. A family may be preparing to sell a home and discover title is still in the deceased settlor’s individual name. A refinance years earlier may have removed the property from the trust, and no one put it back. In other cases, a trust schedule names the property, but no deed was ever signed or recorded. If the trust documents and facts are favorable, Section 850 may allow the successor trustee to obtain a court order confirming that the property belongs to the trust.
The same issue can arise with brokerage accounts, bank accounts, business interests, or other assets. But the analysis is always asset-specific. The stronger the paper trail showing intent to place the asset in the trust, the stronger the Section 850 case tends to be.
That does not mean every mistake can be fixed this way. If the trust never mentions the asset, if ownership changed in a way that conflicts with trust treatment, or if there is a beneficiary dispute about the decedent’s intent, the court may not view Section 850 as the right solution.
Evidence matters more than labels
Families sometimes say, “It was always meant to be in the trust,” and that may be true as a matter of personal understanding. But courts look for objective evidence. The trust document, asset schedules, assignments, deeds, account statements, and estate planning file can all matter. So can the history of how the asset was handled during the settlor’s lifetime.
This is where a careful review is critical. Calling an asset a trust asset does not make it one. On the other hand, a title defect does not automatically force probate if the written record supports trust ownership.
When full probate is still necessary
Full probate is often required when assets remain in the decedent’s sole name and there is no sufficient basis to treat them as trust property. That may be because no trust exists, the trust is silent about the asset, the paperwork is inconsistent, or the value and ownership structure place the asset outside any simpler procedure.
Probate also becomes more likely when there are disputes. If heirs, beneficiaries, or other interested parties disagree about ownership, the matter may not be suitable for the streamlined approach often used in cleaner Section 850 cases. A contested case can quickly become more complicated, and the procedural advantages of a narrow petition may disappear.
Some estates involve a mix of both paths. One parcel of real property may be a strong candidate for a Section 850 petition, while other individually owned assets still require probate or some other transfer procedure. That is why broad assumptions are risky. California estate administration often turns on the details of each asset, not just the existence of a trust.
Section 850 versus full probate for timing and cost
For most families, the practical question is simple: which route gets this resolved with the least delay and expense? In many suitable cases, Section 850 is attractive because it can avoid the lengthy administration associated with full probate. If the asset can be confirmed as trust property, the successor trustee may be able to move ahead under the trust rather than opening an entire estate.
That said, faster does not mean automatic. The petition still must be prepared correctly, supported by the right evidence, and filed in a county where local practice can matter. Courts differ in how they handle these matters, and procedural experience is important. Ex parte handling may be available in some situations, but only when the facts, papers, and local court practices support that approach.
Cost follows the same pattern. A well-founded Section 850 matter is often more efficient than probate, but not every case qualifies. If the petition is weak or the documents are incomplete, the family may spend time pursuing a shortcut that is not actually available. A realistic legal analysis at the outset usually saves money compared with guessing.
How to evaluate the right path
The first step is to gather the trust, all amendments, schedules of assets, deeds, account statements, and any estate planning documents that show how the asset was supposed to be held. If the issue involves real estate, current title records and any refinance history are often essential.
The next step is to ask a very focused question: what written evidence shows that this specific asset was intended to be trust-owned? That question is more useful than asking whether the decedent generally wanted to avoid probate. General intent helps explain the story, but courts decide ownership based on documents and legally significant facts.
From there, the analysis becomes practical. Is the asset clearly identified in the trust? Was there an assignment? Was title removed from the trust at some point? Are there conflicting beneficiaries or family members? Is there a pending sale that creates timing pressure? These issues shape whether Section 850 is a strong fit or whether full probate is the safer answer.
For California trustees, families, and professionals facing a title defect, specialized review can make a real difference. A narrow problem often needs a narrow solution, and a Heggstad-focused practice such as Heggstad Help is built around exactly that type of analysis.
The real decision is not speed versus formality
The phrase section 850 versus full probate can sound like a simple comparison between a quicker option and a slower one. In practice, the real issue is whether the law supports trust administration at all for the asset in question. If it does, Section 850 can be a powerful tool. If it does not, probate is not a failure. It is simply the correct procedure.
For families already dealing with a death, trust administration, or a delayed property sale, that distinction matters. The goal is not to force every case into a Heggstad petition. The goal is to identify the cleanest legally supportable route, fix the title problem, and move administration forward with as little friction as the facts allow.
If you are staring at a deed, trust schedule, or account statement that does not match what the trust was supposed to own, the best next step is usually not to wait and hope the problem solves itself. A prompt document review can tell you whether the asset belongs in a Section 850 petition, a probate case, or a different transfer process entirely – and that clarity is often what gets everything else moving again.
