When siblings or other co-owners inherit a house together and can’t agree on whether to sell it, California law lets any one of them force the issue through a partition action.

Filed under Code of Civil Procedure section 872.210 and the sections that follow, a partition case lets a single co-owner — even one holding a small minority share — ask a judge to divide the property or, far more often for a single house, order it sold with the proceeds split among the owners.

Here is how that process actually works, section by section, plus the newer protections state law wrote specifically for cotenants who inherited property together.

Who Can File a Partition Action

CCP §872.210(a) gives the right to file to co-owners of personal property and to anyone holding a present, future, or concurrent interest in real property that others also hold — whether as tenants in common, joint tenants, or through successive interests such as a life estate followed by a remainder.

That language isn’t limited to equal owners. An heir who inherited an eighth of a house alongside seven siblings has the same statutory right to file as someone who owns half.

The one carve-out is §872.210(b): spouses and putative spouses can’t use this chapter to divide community or quasi-community property — that goes through family court instead.

Once filed, CCP §872.230 requires the complaint to describe the property, name every person who holds a recorded interest in it, and state the plaintiff’s share along with everyone else’s as far as it’s known.

CCP §872.250 then lets the filing heir record a lis pendens — a notice recorded with the county recorder that puts any future buyer, lender, or title company on notice that ownership of the property is in active litigation.

This is often the moment the dispute becomes real to the other heirs, because a title company won’t insure a sale once a lis pendens shows up on a preliminary report.

A partition action is also a different tool than a quiet title action, which resolves who actually holds title in the first place rather than how to divide a title everyone already agrees on.

A partition complaint under CCP §872.230 has to do more than name the property.

It must identify every person with any recorded interest — including a lender holding a mortgage or a spouse with a community-property claim through one of the heirs — state the plaintiff’s own interest, and describe the interests of every other party as far as the plaintiff can determine them.

Getting that list wrong, by leaving out a cotenant or misstating a share, is one of the more common ways a filed case gets delayed while the complaint is amended and everyone is served again.

The Interlocutory Judgment That Sets Everything in Motion

Under CCP §872.710, a co-owner’s right to partition is essentially unconditional absent a binding agreement waiving it.

Once the court confirms the ownership shares and the right to partition, CCP §872.720 directs the court to enter an interlocutory judgment of partition. “Interlocutory” means it isn’t the final word in the case — it is the order that locks in each party’s percentage of ownership and sets the division method in motion, with the referee process and, usually, a sale still to come.

Dividing the Property vs. Forcing a Sale

The statute’s default preference, under CCP §872.810, is division “in kind” — physically splitting the property among the owners according to their interests. That works for a large, subdividable parcel of farmland or raw acreage.

It almost never works for one house on a single residential lot, because you cannot cut a three-bedroom home into eighths.

CCP §872.820 covers exactly that situation: when the court finds the property can’t be divided without substantial injury to the parties’ interests, it orders a sale instead, with proceeds divided according to ownership share.

For larger or mixed-use properties, CCP §872.830 allows a hybrid — partial physical division combined with a sale of the remainder — when some portions can reasonably be split off and others can’t.

Courts weigh practicality heavily here: a single-family home with one driveway, one set of utility connections, and a lot too narrow to subdivide under local zoning is treated as functionally indivisible almost every time, which is exactly why most heir disputes over one house end in a sale rather than a physical split.

Appointing a Referee to Carry Out the Judgment

Once the court orders a sale or a physical division, CCP §873.010 directs it to appoint a referee to carry that order out. The referee is the court’s own officer, not an agent hired by whichever heir filed the case.

CCP §873.020 and §873.030 set the default at one referee, with three available when a party asks and the court finds it warranted — typically on larger or more contested properties.

The parties can propose someone under CCP §873.040, subject to the court’s sign-off, or the court appoints someone itself, often from a standing panel.

CCP §873.050 bars certain interested people from serving, and CCP §873.060 makes clear the referee’s authority comes from the court’s order, not from any of the owners — which matters because it means the referee answers to the judge, not to whichever sibling wanted the sale.

How the Referee Actually Divides or Sells the House

When the court orders a physical division, CCP §873.210 has the referee carry it out, and CCP §873.240 allows division by lots or parcels where the property can be separated that way.

Because an equal physical split is rarely possible, CCP §873.250 authorizes owelty — a cash payment one owner makes to another to equalize value when the division itself can’t be made perfectly even.

A sibling who ends up with the larger or better-located portion, in other words, can be ordered to pay cash to the sibling who got less, so the economic result still matches everyone’s ownership share even though the dirt wasn’t split evenly.

When the court orders a sale instead, CCP §873.510 authorizes the referee to carry it out, and CCP §873.520 lets the court or referee choose between a public auction and a private sale, whichever is likely to bring the better price, with the referee reporting the outcome back to the court.

CCP §873.600 lets the court set specific methods and terms for the sale, or lets the parties agree on terms themselves, subject to the court’s approval.

Confirming the Sale and Disbursing the Money

A referee’s sale isn’t final the moment a buyer signs a contract. CCP §873.720 requires the referee to report the sale back to the court, which holds a noticed hearing to confirm it — or set it aside — before it closes.

Families who have been through a probate sale will recognize the concept; it functions much like the overbid process that applies to some probate sales of real property, where an accepted offer still has to survive a court hearing before it’s truly final and anyone can show up to top it.

Once the court confirms the sale, CCP §873.810 orders disbursement of the proceeds.

CCP §873.820 then governs how those proceeds get applied: first to the costs of the partition action itself and to any liens or encumbrances on the property — mortgage payoff, delinquent property tax, judgment liens — and only after that is the remainder divided among the co-owners according to their ownership interests.

A sibling holding a 25% share should expect roughly a quarter of what’s left after debts and costs, not a quarter of the gross sale price.

Who Actually Pays for the Lawsuit

CCP §874.010 treats the costs of a partition action — referee fees, the cost of sale, and reasonable attorney’s fees for counsel whose work benefited all the co-owners in common, not just the filing party — as chargeable against the property or the sale proceeds, rather than paid entirely out of pocket by the heir who filed.

CCP §874.040 gives the court discretion to apportion those costs among the parties in proportion to their ownership interests, and to adjust that split when fairness calls for it, such as when one owner’s bad faith or unnecessary obstruction ran up the bill.

In practice, the overall cost usually comes out of the sale proceeds before anyone gets paid, which is part of why a drawn-out partition fight can meaningfully shrink what every heir ultimately walks away with — including the heir who wanted to sell in the first place.

If the estate also has a Medi-Cal estate recovery claim outstanding, that debt gets resolved before any heir’s share is calculated, on top of the partition costs.

Special Rules for Heirs: The Partition of Real Property Act

California added a second layer of procedure specifically for cotenants in Chapter 10 of this title, CCP §§874.311–874.323.

The Legislature originally enacted it as the Uniform Partition of Heirs Property Act through Assembly Bill 633 in 2021, effective January 1, 2022, aimed narrowly at “heirs property” — real estate held in tenancy in common with no agreement governing how to partition it, commonly created when a house passes to several relatives by inheritance.

In 2022, Assembly Bill 2245 amended and renamed the law — CCP §874.311 now calls it the Partition of Real Property Act — and broadened it, for actions filed on or after January 1, 2023, to cover any real property held in tenancy in common where no recorded agreement binding all the cotenants governs partition.

That broader scope still reaches the overwhelming majority of sibling and family co-ownership disputes, which is why heirs are the group most likely to actually use it.

The Act doesn’t replace the general partition statute described above; it sits on top of it, aimed at keeping co-owners — often family members — from losing their share to a rushed or lowball forced sale.

A case that qualifies still starts the same way — a complaint under §872.230, a possible lis pendens under §872.250, and an interlocutory judgment under §872.720 — before the heirs-focused appraisal and buyout steps below take over in place of jumping straight to a referee’s sale.

The Cotenant Buyout Right, Step by Step

Before anything is sold, CCP §874.316 requires the court to set the property’s fair market value through an independent appraisal, with notice of the determined value sent to every party and an opportunity to object to it.

CCP §874.317 then gives any cotenant who did not ask for a sale the right to buy out the ownership share of the cotenant or cotenants who did, at that court-determined value — effectively letting a sibling who wants to keep the house buy the others out at an appraised, court-supervised price before the property ever reaches the open market.

If the buyout doesn’t cover every cotenant who wanted a sale, CCP §874.318 has the court decide between partition in kind — still the preferred outcome unless the factors in CCP §874.319 show it would greatly prejudice the owners as a group — or a sale carried out under CCP §874.320.

That section’s default method is an open-market sale: the parties get ten days to agree on a real estate broker the court will appoint, or the court appoints a disinterested one itself, and that broker markets the property commercially, at or above the court-determined value, for a reasonable period.

Only if that process doesn’t produce a qualifying offer does the court fall back to a sealed-bid sale or an auction under the general referee-sale rules in Chapter 6.

CCP §874.321 requires the broker to file a report on the results, and CCP §874.321.5 apportions the costs of this special process in a manner similar to the general cost rules.

Note that CCP §874.322 was repealed as part of the 2022 amendment that renamed and broadened the Act — the appraisal, buyout, and open-market-sale provisions above remain current, operative law.

CCP §874.323 separately confirms the Act’s electronic-signature provisions aren’t preempted by the federal E-SIGN Act, so required notices and consents in these cases can be handled electronically.

When Threatening (or Filing) a Partition Action Is the Wrong Move

Partition is a court process built as a last resort, and it behaves like one.

Referee fees, appraisal costs, a broker’s commission even on a court-supervised sale, and attorney’s fees for the lawyers involved typically come out of the sale proceeds before any heir is paid — meaning everyone’s share shrinks, not only the share of whoever didn’t want to sell.

The timeline runs long: from filing to a confirmed sale and disbursed funds, a contested case commonly takes many months, and well over a year isn’t unusual once there’s a real fight over the appraised value or the buyout price.

And litigation between siblings over a parent’s house tends to outlast the sale itself — a courtroom win rarely repairs what the lawsuit cost the family in the meantime.

Even the heir who “wins” a partition judgment often ends up with less net cash and a permanently strained relationship with the people they grew up with, which is a cost no appraisal line item ever captures.

Before anyone files a partition complaint, it’s worth trying the cheaper path first. Get one independent, as-is value in writing that every heir can see, so the conversation is about a real number instead of competing guesses.

Consider a private buyout, where one heir simply buys the others out at that figure, without the court’s appraisal, notice, and hearing machinery attached.

Or agree to a voluntary sale on the open market, or to a direct buyer, and let one escrow split the proceeds among everyone with a signature, rather than a judge.

A formal partition action earns its cost when one or more co-owners genuinely won’t engage, can’t be located, or are using delay itself as leverage — situations where the statute is the only real way to move the house forward.

Short of that, it’s usually the most expensive way to reach an outcome the family could have agreed to on its own.

If the house hasn’t cleared probate yet, it’s also worth checking whether probate is even required before a sale, since that question usually has to be answered before any partition case can move forward anyway.

If your family has reached the point of weighing a partition action over a house you inherited together, putting a straightforward cash number on the table is often what finally lets everyone agree on a path, and we can provide a no-obligation cash offer whether every heir has signed on yet or not.
