How a Probate Code § 850 Petition Brings a Disputed House Back Into a California Estate

A Probate Code section 850 petition is the court order an executor, administrator, or heir files when a house that legally belongs to a decedent’s estate is sitting in someone else’s name or someone else’s possession.

It is filed inside the existing probate case, heard by the probate judge, and it is the specific tool California law gives an estate representative for pulling disputed real property back where it belongs before anyone can sell it.

This is not the same thing as a Heggstad petition, which is a narrower use of the same statute for a house the decedent meant to put in a trust but never got around to deeding — we’ve covered that specific scenario separately.

What follows is the broader situation: a sibling who took the deed out of the estate, a caregiver who ended up on title, or a joint tenancy claim nobody in the family agreed to.

What Probate Code § 850 Actually Authorizes

Section 850 is not one rule — it is a list of specific situations in which a petition can be filed, and the list matters because a petition has to fit one of them to get a hearing.

Subdivision (a)(2), the part that applies to decedents’ estates, covers four circumstances: a written contract the decedent should have completed before dying (two variations of this), property the decedent died holding title to or possessing that someone else now claims (§850(a)(2)(C)), and — the subsection most relevant here — property the decedent had a claim to where title or possession is held by someone else (§850(a)(2)(D)).

That last category is where most disputed-property cases land: the house legally belongs in the estate, but a third party is holding the deed, occupying the property, or otherwise standing between the estate and the asset.

In practice, §850(a)(2)(D) petitions show up in a handful of recurring patterns. A sibling who lived with an aging parent gets added to the deed shortly before the parent’s death, and the other heirs believe it was the product of undue influence rather than a genuine gift.

A caregiver convinces a vulnerable homeowner to sign a quitclaim deed. Two names appear on a deed as joint tenants, but one side argues the joint tenancy was never intended to override the will or was created through a forged signature.

In every version, the estate’s representative — or any interested heir if the representative won’t act — has to go to the probate court and ask for an order establishing that the property, or an interest in it, actually belongs to the estate rather than to the person currently holding it.

Why This Is Not a Heggstad Petition

Because both procedures run through the same code section, people often use “Heggstad petition” as shorthand for any §850 filing, which causes confusion when the facts don’t fit.

A Heggstad petition is for an entirely different problem: the decedent set up a living trust, clearly intended a specific house to be part of it, but never signed or recorded a deed transferring the property into the trust’s name before dying.

The successor trustee asks the court to confirm the trust already owned the house in substance, even though the paperwork was never finished.

Nobody outside the family is typically fighting over who the rightful owner is — the dispute, if there is one, is usually about whether the decedent’s intent was clear enough.

The scenario this article covers is the opposite in character. There is usually an actual adverse party — a sibling, a caregiver, a co-tenant, sometimes someone outside the family entirely — who is holding the property or title and does not agree that it belongs to the estate.

The petition is not confirming an intent that everyone already accepts; it is asking the court to decide a genuine ownership dispute.

That difference changes how the case is litigated, who has to be served, and how long it realistically takes, which is the rest of what this article walks through.

How the Petition Is Filed and Heard

An 850 petition is filed with the probate department of the superior court in the county where the estate is already pending — it is not a separate lawsuit in civil court, even though a contested one ends up looking a great deal like one.

The petitioner (the personal representative, or an interested heir if the representative is unwilling or is the one holding the disputed property) files a verified petition setting out the facts supporting the claim: how the property came to be in someone else’s name or possession, why it belongs in the estate, and what specific order the court should make.

Because the statute requires the petition to “set forth facts upon which the claim is based,” a bare assertion that something is unfair will not get past the pleading stage — the petition has to describe the actual chain of events.

Notice is where an 850 petition starts to diverge from an ordinary probate filing. Routine probate matters generally use the standard notice period under Probate Code §1220, which runs at least 15 days before the hearing.

An 850 petition aimed at a third party’s claim to real property, though, is treated differently in practice because it can bind someone who was never otherwise a party to the probate case.

Probate practitioners handling these petitions typically serve the respondent with notice and a copy of the petition under the service rules that apply to civil summonses (Code of Civil Procedure §§413.10–417.40), which generally means at least 30 days before the hearing rather than the shorter probate-notice floor.

The exact service requirements can depend on who is being served and where, so confirm the applicable notice period with a probate attorney before setting a hearing date rather than assuming either figure applies automatically.

Because the property at issue is real estate, the petitioner’s attorney will also typically record a Notice of Pendency of Action — the document most people still call a lis pendens — against the property in the county recorder’s office once the petition is filed.

That single step is often the most consequential thing that happens procedurically, because it is what makes the dispute visible to anyone who checks title, including a prospective buyer or their lender.

What Happens When the Petition Is Contested

If nobody objects, the hearing can be comparatively quick — the court reviews the petition, confirms notice was properly given, and signs an order. That is the uncontested track, and it is closer to how a Heggstad petition usually resolves. A disputed-property petition under §850(a)(2)(D) rarely stays uncontested, because by definition someone is holding the property and disagrees that it belongs elsewhere.

The respondent can file a written objection before the hearing or raise one orally at the hearing itself, though filing in advance in writing is the safer route if the goal is to actually preserve the objection.

Once a real objection is on file, the matter stops functioning like a routine probate filing and starts functioning like ordinary civil litigation, just conducted within the probate case rather than a separate lawsuit.

That means written discovery, depositions, motions, and ultimately a trial on the ownership question if the parties cannot settle it — all heard by the probate judge rather than being transferred to a civil department.

This is the part people underestimate going in: an 850 petition is a probate-code mechanism, but a contested one is litigated like a civil property or fraud case, and it can take as long as one.

What the Court Can Order

If the estate prevails, the order under §850 directs the person holding the property or title to convey it, or to acknowledge the estate’s interest in it, restoring the house to the estate so the personal representative can deal with it along with everything else in the administration.

Where the court finds the property was taken from the estate through bad faith, Probate Code §859 allows it to go further: the person who wrongfully took, concealed, or disposed of the property can be ordered to pay double its value and the petitioner’s attorney’s fees, on top of returning the property itself.

That provision exists precisely for the caregiver-undue-influence and sibling-self-dealing scenarios this article is about, and it is one reason these petitions are worth pursuing even when the dispute looks expensive to litigate.

An heir considering whether a dispute fits §850(a)(2)(D) at all, versus a different remedy, should also know this procedure sits alongside others that solve related but distinct problems.

If two or more co-owners already hold undisputed title together and simply cannot agree on what to do with the house, a partition action is usually the correct tool rather than an 850 petition — we’ve written separately about how a partition action forces a sale between heirs who can’t agree.

The distinction matters: partition assumes everyone agrees who owns what and disputes only what to do about it, while an 850 petition exists because the ownership itself is in dispute.

How an 850 Petition Affects the Timeline to Sell

Once a lis pendens is recorded and the petition is pending, the house is effectively frozen for sale purposes, regardless of what the probate case’s own timeline looks like otherwise.

A title company will generally not issue title insurance on a property with an open lis pendens, and without insurable title, most lenders will not fund a buyer’s purchase and most buyers will not close.

That holds true whether the underlying probate administration is otherwise moving quickly or is already dragging — the title cloud created by the dispute is a separate obstacle from the ordinary probate process, and it does not clear until the petition is resolved by settlement, court order, or dismissal and the lis pendens is released or expunged from record.

This is also why timing a listing matters. Marketing a disputed property before the petition is resolved, without disclosing the pending litigation, is a fast way to lose a buyer’s trust and potentially their earnest money deposit once the title search turns up the recorded notice.

The more realistic approach is to let the petition run its course — or reach the settlement stage, where the parties often agree to a conveyance without a full trial — and then market the property once title is clean enough for a title company to insure it.

When a Cash Sale Is the Wrong Move Here

It needs to be said plainly: while title is actively disputed under an open 850 petition, selling the house — to us, to another cash buyer, or on the open market — is generally not something a serious buyer or a title company will complete.

We buy directly or bring a vetted cash buyer to the table for houses with clean or clearable title, including many estates still in active probate administration.

But a property with a recorded lis pendens and a contested ownership claim is a different situation, because the obstacle is not the probate timeline, it is the unresolved question of who actually owns the house.

Any buyer willing to sign a contract under those conditions should raise real questions about why, and an executor or heir in this position is usually better served getting the ownership question resolved first, even if that takes months, than accepting an offer nobody can actually close.

Where a sale can sometimes move forward sooner is when the petition is uncontested, or when the parties reach a settlement early and the respondent agrees to convey the property or quitclaim their claim as part of resolving the case.

In that situation, the lis pendens can be released once the settlement is documented and recorded, and the estate can proceed to sell on whatever timeline the rest of the probate administration allows — which, once the house is confirmed as an estate asset, folds back into the ordinary rules for a probate sale, including court confirmation if the representative lacks full independent authority.

We’ve broken down how that confirmation and overbid process works for anyone who gets to that stage.

What Happens After the Court Rules

If the court grants the petition, the order itself typically functions as the instrument that re-establishes the estate’s interest — in many cases a certified copy of the order can be recorded with the county recorder in place of a new deed, putting the public record in line with the court’s decision.

The personal representative then has what every estate needs before selling a house: clear, recordable authority showing the property belongs to the estate.

From there, the house moves through the same administration steps as any other estate asset — appraisal by the probate referee if that has not already happened, notice to creditors if the claim period is still open, and eventually a sale under whatever authority the representative holds.

If the petition is denied, the respondent keeps the property, and the estate’s options narrow to accepting that outcome or pursuing an appeal, which adds months, sometimes longer, before anyone can act on the property either way.

Either outcome is a reason to get a realistic read on the strength of the underlying claim before filing — a probate litigator can usually tell early whether the facts support a §850(a)(2)(D) claim or whether the dispute is weaker than it feels from inside the family.

First Steps if You Think a House Was Wrongly Taken Out of the Estate

1. Pull the recorded deed history on the property from the county recorder to see exactly when and how title changed hands
2. Gather anything showing the decedent’s actual intent — prior deeds, a will or trust, medical records if incapacity or undue influence is part of the claim
3. Talk to a California probate litigator early about whether the facts fit §850(a)(2)(D), a different probate remedy, or neither
4. If you are the personal representative, do not wait for a willing third party to volunteer the property back — file before more time passes and evidence gets harder to gather
5. Keep the property insured and maintained while the dispute is pending, since an empty or neglected house is a liability on top of a title dispute

An 850 petition over disputed estate property is detailed litigation, not a form you fill out, and the right strategy depends on facts a short article cannot cover.
