California’s Partition of Real Property Act: What Litigants Need To Know.
For generations, California partition law offered a relatively straightforward remedy for co-owners seeking to sever their concurrent interests in real property: file a partition action, and the court would either divide the property in kind or order a sale. See Cal. Civ. Proc. Code § 872.810; see also Cal. Civ. Proc. Code § 872.820. In practice, however, that framework often produced inequitable outcomes—particularly for families whose shared ownership traced back through inheritance rather than commercial investment. In 2021, the California Legislature responded by enacting the Partition of Real Property Act (“PRPA”), codified at Code of Civil Procedure sections 874.311 through 874.323, which fundamentally restructured the procedural landscape for partition litigation in this state. See Cal. Civ. Proc. Code §§ 874.311–874.323 (added by Stats. 2021, ch. 119 (AB 633), § 2).

Historical Background and Policy Motivation
The PRPA draws directly from the Uniform Partition of Heirs Property Act (“UPHPA”), a model act approved and recommended for enactment in all states by the National Conference of Commissioners on Uniform State Laws (the Uniform Law Commission) in 2010. See 7 U.S.C. § 2266b(a)(1)(A) (recognizing state enactments of the UPHPA). The UPHPA was developed to address a well-documented problem: the involuntary dispossession of families—disproportionately middle- to low-income families and rural African-American families—from real property through forced partition sales. See Uniform Law Commission, Uniform Partition of Heirs Property Act (Summary). Under traditional partition law, a single cotenant holding even a small fractional interest could force a judicial sale, often at well below market value, displacing families from land that had been passed down for generations. Id.
California enacted the PRPA through Assembly Bill 633 (Stats. 2021, ch. 119), effective January 1, 2022. The Legislature subsequently amended and refined the Act through AB 2245 (Stats. 2022, ch. 82), effective January 1, 2023, which broadened the Act’s scope beyond “heirs property” to apply to all real property held in tenancy in common where no binding partition agreement exists among the cotenants. Cal. Civ. Proc. Code § 874.311(b). As amended, the PRPA applies to all partition actions filed on or after January 1, 2023. Cal. Civ. Proc. Code § 874.311(c).
Key Procedural Requirements
The PRPA imposes several new procedural obligations on litigants at each stage of a partition action. Practitioners must be familiar with these requirements, as they significantly alter the traditional partition timeline and strategy.
Applicability and Threshold Determination
The PRPA applies to real property held in tenancy in common where there is no agreement in a record binding all the cotenants that governs partition of the property, and only to actions filed on or after January 1, 2023. Cal. Civ. Proc. Code § 874.311(b)–(c). Under section 874.313, covered property “shall be partitioned under this chapter unless all of the cotenants otherwise agree in a record.” Cal. Civ. Proc. Code § 874.313(a). The PRPA supplements the existing provisions of Title 10.5 and controls over any inconsistent provisions. Cal. Civ. Proc. Code § 874.313(b).
Importantly, several categories of property and actions fall outside the Act’s reach. The PRPA does not apply to joint tenancies, community property, or partnership property—only tenancies in common are covered. See Cal. Civ. Proc. Code § 874.311(b); see also Cal. Civ. Proc. Code § 872.210(b) (separately excluding community property partition actions between spouses). The Act also does not govern personal property partitions, which remain subject to the general provisions of Title 10.5. And where all cotenants have entered into a binding written agreement governing partition, the PRPA yields to the terms of that agreement. Cal. Civ. Proc. Code § 874.311(b). Practitioners should evaluate these threshold questions at the outset of any partition matter to determine whether the PRPA framework applies.
Notice and Signage Requirements
Section 874.314 preserves existing methods of service in partition actions but adds a new requirement: if the plaintiff seeks an order of notice by publication, the plaintiff must, within 10 days of the court’s determination, post and maintain a conspicuous sign on the property while the action is pending. Cal. Civ. Proc. Code § 874.314(b). The sign must state that the action has commenced and identify the court’s name, address, and the property’s common designation. Id. The court may also require the sign to include the names of the plaintiff and known defendants. Id.
Court-Appointed Referees
If the court appoints referees under section 874.315, each referee must be disinterested and impartial and may not be a party to or a participant in the action. Cal. Civ. Proc. Code § 874.315.

Appraisal and Valuation Procedures
Section 874.316 establishes a structured appraisal framework. Unless all cotenants agree to a value or an alternative valuation method, the court must order an appraisal by a disinterested real estate appraiser licensed in California, who determines the fair market value of the property assuming sole ownership of the fee simple estate. Cal. Civ. Proc. Code § 874.316(d). The appraiser files a sworn or verified appraisal with the court. Id.
Within 10 days after the appraisal is filed, the court must send notice to each party at their known address stating (1) the appraised fair market value, (2) the availability of the appraisal at the clerk’s office, and (3) the right to object within 30 days. Cal. Civ. Proc. Code § 874.316(e). The court then conducts a hearing—not sooner than 30 days after notice—to determine the property’s fair market value, considering both the court-ordered appraisal and any other evidence of value offered by a party. Cal. Civ. Proc. Code § 874.316(f).
Buyout Rights
Section 874.317 introduces a critical right of first refusal. If any cotenant has requested partition by sale, the court must, after the determination of value, notify the parties that any cotenant except the one requesting sale may buy out the requesting cotenant’s interests. Cal. Civ. Proc. Code § 874.317(a). The purchase price is calculated as the entire parcel’s determined value multiplied by the selling cotenant’s fractional ownership. Cal. Civ. Proc. Code § 874.317(c).
Cotenants have 45 days from notice to elect to purchase. Cal. Civ. Proc. Code § 874.317(b). If multiple cotenants elect to buy, the right is allocated proportionally based on each electing cotenant’s existing fractional ownership. Cal. Civ. Proc. Code § 874.317(d)(2). If the purchase is elected, the court sets a payment deadline of not less than 60 days after notice, and if all electing cotenants pay, the court issues an order reallocating interests. Cal. Civ. Proc. Code § 874.317(e)(1). A secondary 20-day period allows remaining cotenants to purchase any interests left unpaid by defaulting cotenants. Cal. Civ. Proc. Code § 874.317(f).
Preference for Partition in Kind
Sections 874.318 and 874.319 codify a strong statutory preference for partition in kind over partition by sale. If the buyout process does not resolve the action, the court “shall order partition in kind” unless it finds, after weighing statutory factors, that partition in kind “will result in great prejudice to the cotenants as a group.” Cal. Civ. Proc. Code § 874.318(a).
The factors the court must weigh under section 874.319 include: (1) whether the property can practicably be divided; (2) whether the aggregate fair market value of divided parcels would be materially less than the whole; (3) the collective duration of family ownership; (4) sentimental or ancestral attachment; (5) the lawful use being made of the property; (6) cotenant contributions to taxes, insurance, maintenance, and improvements; and (7) any other relevant factor. Cal. Civ. Proc. Code § 874.319(a)(1)–(7). No single factor is dispositive. Cal. Civ. Proc. Code § 874.319(b).
Sale Procedures and Cost Apportionment
If sale is ordered, section 874.320 requires an open-market sale unless the court finds that sealed bids or auction would be more economically advantageous. Cal. Civ. Proc. Code § 874.320(a). The court appoints a licensed California real estate broker, who must offer the property at no less than the court-determined value. Cal. Civ. Proc. Code § 874.320(b). The broker must file a report with the court within seven days of receiving a qualifying offer. Cal. Civ. Proc. Code § 874.321(a).
Finally, section 874.321.5 modifies the longstanding cost-apportionment framework of section 874.040. Under section 874.040, the court “shall apportion the costs of partition among the parties in proportion to their interests or make such other apportionment as may be equitable.” Cal. Civ. Proc. Code § 874.040. That general rule gives the court broad discretion, and it has historically meant that all cotenants—including those who never wanted the partition—bear their proportionate share of appraisal fees, referee fees, broker commissions, and other expenses enumerated in section 874.010. See Cal. Civ. Proc. Code § 874.010(a)–(e). Section 874.321.5 now overlays a presumptive limitation on that discretion: the court may still apportion costs pursuant to section 874.040, but it “shall not apportion the costs of partition to any party that opposes the partition unless doing so is equitable and consistent with the purposes of this chapter.” Cal. Civ. Proc. Code § 874.321.5. In practice, this creates a rebuttable default that the party who initiated or sought the partition bears the costs, while cotenants who opposed it are presumptively shielded—unless the court affirmatively finds that charging the opposing party would be both equitable and consistent with the PRPA’s protective purposes. The two provisions now operate in tandem: section 874.040 supplies the general framework and menu of permissible cost categories, while section 874.321.5 constrains the court’s discretion as to who bears those costs in PRPA-governed actions.
Practical Implications for California Litigators
The PRPA fundamentally changes how California real estate attorneys approach partition disputes. The Act’s buyout mechanism introduces a negotiation dynamic that did not exist under prior law—parties seeking to retain property now have a statutory avenue to purchase out co-owners who want a sale. Attorneys representing retaining cotenants should be prepared to move quickly within the 45-day and 60-day statutory windows.
The heightened preference for partition in kind means that parties seeking a sale face a more demanding evidentiary burden. The multi-factor “great prejudice” analysis under section 874.319 invites the court to consider noneconomic values like family history and sentimental attachment—factors that were not traditionally central to partition analysis. Practitioners should consider marshaling evidence of their client’s long-term connection to the property early in the case.
Finally, the cost-apportionment protections in section 874.321.5 shift litigation risk away from parties who did not initiate the partition, creating an asymmetry that may affect settlement dynamics.
The PRPA represents a significant modernization of California partition law. Practitioners handling co-ownership disputes should ensure they are operating under the new framework and advising clients accordingly.The blog post is now in draft form for your review. It covers all three areas you requested:
- Historical background, including the UPHPA model act origins, the policy motivations around forced partition sales and family property loss, and the legislative progression from AB 633 (2021) through the AB 2245 amendments (2022) that broadened the Act’s scope beyond heirs property to all tenancies in common.
- Procedural requirements, walking through the Act’s provisions in sequence: applicability thresholds, notice and signage obligations, the appraisal framework with its objection deadlines, the buyout mechanism and its 45-day and 60-day windows, the multi-factor partition-in-kind preference, open-market sale procedures, and cost apportionment protections.
- Practical implications for litigators, touching on the new buyout negotiation dynamics, the heightened evidentiary burden for parties seeking a sale, and the cost-shifting asymmetry under section 874.321.5.
One note: I was unable to locate California appellate decisions specifically interpreting the PRPA in my research sources, which is consistent with the Act’s relatively recent effective date. The draft accordingly focuses on the statutory text. Feel free to request any edits to tone, length, emphasis, or citation format.

Frequently Asked Questions About California Partition Actions
What is the California Partition of Real Property Act?
The Partition of Real Property Act (PRPA) is a California law governing certain partition actions involving real property held in tenancy in common. It established additional procedures addressing valuation, buyouts, partition in kind, sales, and allocation of partition costs. The Act is codified in California Code of Civil Procedure sections 874.311 through 874.323.
When does the Partition of Real Property Act apply?
The PRPA generally applies to real property held in tenancy in common when there is no binding agreement among the cotenants governing partition. Under the article’s discussion of CCP § 874.311, the Act applies to partition actions filed on or after January 1, 2023.
Does the PRPA apply to joint tenancy property?
No. The Act applies to qualifying property held in tenancy in common and does not apply to joint tenancies, community property, or partnership property.
Can a co-owner force a sale of property in California?
A co-owner may have the right to seek partition, but the PRPA can significantly affect how that request proceeds. The Act establishes a buyout procedure and creates a statutory preference for partition in kind before a sale is ordered in applicable cases.
Can one co-owner buy out another during a partition action?
Yes. Under CCP § 874.317, when a cotenant requests partition by sale, other qualifying cotenants may have an opportunity to purchase the requesting cotenant’s interest. The purchase price is based on the determined value of the entire parcel multiplied by the selling cotenant’s fractional ownership interest.
How long does a co-owner have to exercise the buyout right?
Under the PRPA framework discussed in the article, a qualifying cotenant has 45 days from notice to elect to purchase the requesting cotenant’s interest. If the purchase is elected, the court sets a payment deadline of at least 60 days after notice.
What is partition in kind?
Partition in kind means physically dividing the property among the cotenants rather than selling the entire property. Under the PRPA, the court has a statutory preference for partition in kind unless dividing the property would result in great prejudice to the cotenants as a group.
What factors does a court consider when deciding whether to partition property in kind?
The court considers factors including whether the property can practically be divided, whether dividing it would materially reduce its aggregate value, the duration of family ownership, sentimental or ancestral attachment, the property’s lawful use, contributions toward taxes and maintenance, and other relevant factors.
How is property valued in a California partition action?
Unless the cotenants agree on a value or another valuation method, the court must order an appraisal by a disinterested California-licensed real estate appraiser who determines the property’s fair market value assuming sole ownership of the fee-simple estate. Parties may object to the appraisal and present other evidence of value.
How is a property sold under the Partition of Real Property Act?
When a sale is ordered, the PRPA generally requires an open-market sale, unless the court determines that sealed bids or an auction would be more economically advantageous. A licensed California real estate broker is appointed to market the property at no less than the court-determined value.
