Your mother passes away and leaves the family home in equal shares to you and your two siblings. One sibling wants to sell immediately. Another wants to rent it out. You want to keep it as a gathering place for the next generation. Three people, one property, and no way forward together.
The legal process for resolving this kind of deadlock is called a partition action, a civil lawsuit that allows co-owners of real property to either divide the property physically or force its sale when they cannot agree. That process is called a partition action. It does not require a majority vote, a court order to begin, or anyone else’s consent. One co-owner with even a fractional interest can file, and once they do, every other co-owner is forced to respond, whether they wanted this or not.
A partition action is a lawsuit that lets any co-owner of California real estate force the issue when co-owners cannot agree. The court can physically divide the property or, far more often with inherited homes, order it sold and split the proceeds. Since January 1, 2023, the Partition of Real Property Act has shifted the balance toward co-owners who want to keep the property. Before a sale can be ordered, the court sets fair market value through an independent appraisal, and the co-owners who did not seek partition get first right to buy out the departing owner at that price. But the right to file remains broad, the process remains adversarial, and the family dynamics that accompany these disputes rarely make them easier to resolve.
What Is a Partition Action in California?
A partition action is a legal proceeding governed by California’s Code of Civil Procedure, beginning at CCP Section 872.010 and following. Under CCP Section 872.210, any owner of an estate of inheritance, an estate for life, or an estate for years in real property held by several persons concurrently may bring this type of action. California courts generally treat partition as a matter of right among co-tenants, subject to statutory procedures and equitable adjustments.
A partition can take two fundamental forms.
| Partition in Kind | Partition by Sale |
| The property is physically divided among the co-owners. | The court orders the property sold and the proceeds divided by ownership share. |
| Practical for large parcels of land. | Common for a single-family home or condominium. |
| Favored by California law. | The usual outcome for residential inherited property. |
California law favors partition in kind over a forced sale because a sale compels co-owners to part with property they may desperately want to keep. The burden falls on whoever is seeking a sale to prove that physical division is impractical or would cause significant prejudice to the owners. For a three-bedroom house in Riverside or a condominium in Anaheim, courts generally find that burden easy to meet.
How Did the 2023 Law Change Things for Inherited Property?
Before 2023, California’s partition framework heavily favored whoever wanted to sell. A single co-owner with even a modest fractional interest could file a partition action and force a sale over the objections of every other co-owner. The process was particularly brutal in inherited property situations, where families with emotional ties to a home were compelled to either outbid strangers at a public sale for property they already partially owned or lose it entirely. Predatory investors recognized this. They would purchase a small fractional interest in an inherited family property specifically to trigger the partition process, forcing a distressed sale at below-market value and then purchasing the property themselves at a discount. Families who had held property for generations lost it in months.
California responded with two meaningful changes. First came the Uniform Partition of Heirs Property Act, signed into law in July 2021 and effective January 1, 2022. It applied to heirs property, broadly defined as property where one or more co-tenants acquired title from a relative, living or deceased, and where no agreement governs partition among co-owners.
Then Governor Newsom signed AB 2245 in July 2022, and the Partition of Real Property Act took effect January 1, 2023, codified at CCP Section 874.311 through Section 874.323. The Act eliminated the requirement that property qualify as heirs property, extending its protections to any tenancy-in-common without an existing written agreement governing partition. It applies to all partition actions filed on or after January 1, 2023.
The Buyout Procedure
The most significant protection the Act introduced is a statutory buyout opportunity for non-partitioning co-owners. Before the court considers how the partition will proceed, it must determine the fair market value of the property through an independent appraisal. Once that value is set, the co-owners who did not request partition by sale have the opportunity to purchase the departing co-owner’s interest at that appraised value before any open-market sale is ordered.
This is a meaningful shift from the old rules. Under the prior framework, co-owners who wanted to keep an inherited family home were forced to outbid strangers at a public sale for property they already partially owned. Now they get a fair first opportunity to buy out the departing co-owner at an independently established value. If no co-owner exercises the buyout opportunity, or if they elect to do so but fail to deposit the purchase funds in time, the court proceeds with partition under CCP Section 874.318.
Who Bears the Cost When a Partition Action Is Filed?
Attorney fees and litigation costs in partition cases are handled differently than in a typical civil lawsuit. Under CCP Section 874.010, the costs of partition include reasonable attorney fees necessarily incurred for the common benefit of all co-owners. These costs are generally deducted from the sale proceeds proportionally, so all co-owners share in them based on their ownership interests.
Under the Act, the court generally considers equitable allocation of costs under CCP Section 874.321.5, and may limit shifting costs against a party opposing partition depending on fairness and the purposes of the act. This protects a co-owner who did not want to sell from being saddled with the litigation costs of the party who forced the action, while still allowing the court discretion when equity requires a different result.
Courts also hold broad authority under CCP Section 872.140 to make compensatory adjustments among the parties. A co-owner who has been paying property taxes, mortgage installments, insurance, or maintenance costs that others have not contributed to may seek credit for those expenditures before proceeds are distributed. As the California Court of Appeal stated in Wallace v. Daley (1990) 220 Cal.App.3d 1028, 1035-1036, every partition action includes a final accounting according to the principles of equity for both charges and credits upon each co-tenant’s interest, covering repairs, improvements, taxes, mortgage payments, and insurance paid for the common benefit.
What Does the Partition Process Actually Look Like?
Below is a step-by-step overview of how a typical partition action proceeds in California, from filing through final judgment, including how the process changes under the Act when applicable.
File a Complaint for Partition
The party seeking partition files in the California Superior Court in the county where the property is located. The complaint must identify all co-owners, describe the property and each party’s interest, list any encumbrances such as mortgages, and specify the requested type of partition. Under CCP Section 872.510, all persons with recorded interests must be named as defendants.
Appraisal Under the Act
For cases governed by the Act, early in the case the court must order an independent appraisal of the property’s fair market value. This valuation occurs as part of the statutory process before any final determination on the method of partition. Notice of the appraised value is sent to all parties, who then have a limited window to object or accept it.
Buyout Election
Non-partitioning co-owners decide whether to exercise their statutory buyout opportunity to purchase the departing co-owner’s share at the court-determined appraised value. If they elect to do so, they must deposit the purchase funds with the court within the time set by the judge. A timely deposit resolves the case as to the participating interests and prevents a court-ordered sale.
Interlocutory Judgment
If no buyout is completed, the court holds a proceeding to determine whether the plaintiff is entitled to partition. Under CCP Section 872.720, if partition is confirmed, the court issues an interlocutory judgment that determines each party’s ownership interests and orders partition, along with the manner of partition.
Partition Referee Appointed
Under CCP Section 873.010, the court appoints a partition referee, a neutral third party authorized to carry out the sale. The referee manages the listing, receives offers, and submits a formal report to the court.
Sale, Accounting, and Final Judgment
After the sale closes, the court reviews the referee’s report, addresses equitable adjustments among co-owners, deducts costs of partition, and distributes the net proceeds. Under CCP Section 874.210, the court then enters a final judgment of partition.
Can You Stop or Delay a Partition Action?
There are limited circumstances under which partition may be barred or delayed. A prior written agreement among all co-owners that addresses partition can operate as a waiver under CCP Section 872.710(b). Courts have also recognized waiver in situations where co-owners entered into binding agreements that establish a specific ongoing use of the property, such as a business arrangement.
Outside of a valid waiver, the right to partition is generally treated as a matter of right among co-tenants, subject to statutory procedures. That said, the Act’s statutory buyout process often provides the most practical way for a co-owner who wants to retain the property to do so by purchasing the interests of the co-owners seeking sale at the court-determined value.
Alternatives to a Partition Lawsuit
Partition litigation is slow, expensive, and almost always makes family relationships worse before it makes them better. Most disputes that end up in partition court started with a conversation that could have resolved the issue: one co-owner willing to buy out the others, a rental arrangement that covered the mortgage, a mediator who helped the parties see what trial would actually cost them. The following options exist before, and sometimes during, a partition lawsuit.
Direct buyout. Co-owners negotiate privately for one party to purchase the interests of the others at an agreed price, without court involvement.
Rental and revenue sharing. If the property can generate income, co-owners may agree to rent it and split the proceeds proportionally while deferring the question of sale.
Mediation. A neutral mediator can help co-owners reach a binding settlement outside court, often faster and far less costly than litigation.
Partition by appraisal. Co-owners may agree to obtain an independent appraisal and allow one party to buy out the others at that value, avoiding formal partition proceedings.
Making a genuine effort to resolve the dispute before filing is not just practical. It can also be viewed favorably by the court if litigation becomes necessary.
Key Takeaways
- Any co-owner of California real property held as a tenancy in common has a right to file a partition action under CCP Section 872.210, regardless of how small their ownership interest is.
- The Partition of Real Property Act (CCP Sections 874.311 through 874.323), effective January 1, 2023, requires the court to determine fair market value early through an independent appraisal and gives non-partitioning co-owners a statutory buyout opportunity to purchase the departing co-owner’s interest at that court-determined value.
- California courts prefer partition in kind over a forced sale, but partition by sale remains the most common outcome in residential inherited property disputes in Southern California where physical division is not practical.
- Under the Act, the court generally considers equitable allocation of partition costs under CCP Section 874.321.5 and retains discretion to adjust costs based on fairness and the purposes of the act.
- Co-owners who paid disproportionate expenses such as taxes, mortgage payments, insurance, or necessary repairs may seek equitable credits before proceeds are distributed, under CCP Section 872.140 and the accounting principles affirmed in Wallace v. Daley (1990) 220 Cal.App.3d 1028, 1035-1036.
- A valid written agreement among all co-owners addressing partition can waive the right to file, but absent such an agreement, partition is generally difficult to prevent because it is treated as a matter of right among co-tenants subject to statutory procedures.
- Mediation, direct buyout, and appraisal-based agreements are practical alternatives that can resolve disputes without full litigation and may preserve both financial value and family relationships.
Frequently Asked Questions
Q: Can one sibling force the sale of inherited property in California even if the others disagree?
A: Yes. Under CCP Section 872.210, any co-owner may file a partition action. If the court orders a partition by sale, the property can be sold and the proceeds divided. Under the Act, non-selling co-owners may buy out the interest of the party seeking sale at the court-determined value before any third-party sale under CCP Section 874.317.
Q: How long does a partition action take in California?
A: It depends on the county and complexity. Uncontested cases may resolve in a few months, while disputed cases can take one to two years or longer, especially if value or ownership is contested.
Q: What happens if one co-owner is living in the inherited home?
A: Occupancy does not prevent partition. The court may adjust financial contributions between co-owners, and the occupying co-owner may participate in the buyout process if they want to keep the property.
Q: Does it matter whether property was inherited through a will, a trust, or intestate succession?
A: No. Partition applies to any co-owned property held as tenants in common, regardless of how title was acquired. The Act applies to eligible cases filed on or after January 1, 2023.
Q: Can a co-owner be reimbursed for improvements made to the inherited property?
A: Yes. Under CCP Section 872.140, courts may credit a co-owner for good faith improvements that increased the property’s value, based on evidence of benefit to the property.
Q: What is a partition referee and why does it matter?
A: A partition referee is a court-appointed neutral under CCP Section 873.010 who manages the sale or division of the property and reports to the court. Their actions directly affect the sale process and final distribution. Having an attorney who monitors the referee’s conduct and reviews their reports throughout the process is an important way to protect your interests.
When Co-Owners Cannot Agree, the Clock Starts
Once one co-owner files a partition action, the dynamic shifts. The party who filed has already decided. The party who did not file is now reacting, and every delay costs time and often money. If you are the co-owner who wants to keep the property, your window to exercise a statutory buyout is finite and court-controlled. If you are the co-owner who wants to sell, a co-owner living in the property rent-free or refusing to participate can drag the process out for years. Either way, the longer this goes without legal counsel, the fewer options you have.
