Partition Actions: Forcing the Sale of Co-Owned Property

Co-owning California real estate can become difficult when one owner wants to sell and another refuses. A partition action provides a court process for dividing the property or selling it and allocating the proceeds. But a sale is not automatic, and ownership agreements, statutory buyout procedures, and competing financial claims can affect the result. This article explains who can request partition, how the process works, and what California businesses and individuals should consider before filing.

Who can bring a partition action in California?

Partition is a legal proceeding that ends or restructures shared ownership. Under California Code of Civil Procedure section 872.210, certain owners of real property may bring a partition action. Common examples include siblings who inherited a house, unmarried partners who purchased a home together, and investors who jointly own a rental property.

For qualifying concurrent owners, partition is generally available as a matter of right unless barred by a valid waiver. Code of Civil Procedure section 872.710 addresses the right to partition. A co-owner usually does not need to prove that another owner committed wrongdoing simply to request partition.

Still, the ownership structure matters:

  • Direct ownership: Tenants in common and joint tenants generally have potential partition rights.
  • Entity ownership: Owning an interest in an LLC or corporation that owns real estate does not ordinarily make you a direct co-owner of that real estate.
  • Contractual limits: A co-ownership agreement may restrict partition or establish an alternative exit process.

Before proceeding, review the deed, title report, and any agreements. A disagreement about ownership percentages may need resolution before the court can distribute proceeds.

How does the court process work?

A partition case generally begins with a complaint filed in the county where the property is located. The plaintiff must identify the property, describe the interests involved, and name the appropriate parties. The process also includes recording a notice of pendency of action, commonly called a lis pendens, which alerts others that litigation concerns the property.

The court first determines whether partition is available and establishes the parties’ interests. It may enter an interlocutory judgment directing partition and appoint a referee to carry out the court’s instructions. Depending on the dispute, the case may involve:

  1. Resolving title issues and reviewing claimed ownership shares.
  2. Determining whether special statutory procedures apply.
  3. Choosing physical division or sale, subject to applicable buyout rights.
  4. Reviewing financial adjustments and allocating the net proceeds.

A partition case can require substantial work even when the parties agree that shared ownership should end. Itkin Law’s civil litigation practice assists businesses and individuals with property disputes and related court proceedings.

Will the property be divided, sold, or bought out?

Outside actions governed by the Partition of Real Property Act, California law generally favors physical division, known as partition in kind, unless sale would be more equitable. Code of Civil Procedure sections 872.810 and 872.820 address these alternatives. In an action governed by the Act, the court generally orders partition in kind unless it would result in great prejudice to the cotenants as a group, applying sections 874.318 and 874.319. Dividing a parcel may be feasible for some land, but dividing a single house into separately owned properties is often impractical. Zoning, access, existing improvements, and effects on value all matter.

California’s Partition of Real Property Act, Code of Civil Procedure sections 874.311–874.323, adds important protections. It generally applies to actions filed on or after January 1, 2023, involving property held in tenancy in common when no agreement in a record binding all co-owners governs partition. It is not limited to inherited property.

When the Act applies and any cotenant requests partition by sale, each cotenant who did not request partition by sale may elect, within 45 days after the statutory notice, to buy all interests of the cotenants who requested partition by sale. Under Code of Civil Procedure section 874.317, the purchase price is based on the court-determined value of the entire property multiplied by each selling cotenant’s fractional ownership. The statute provides procedures for allocating interests among multiple buyers and completing the buyout. This is not an unrestricted right for any owner to force a purchase at a price they choose.

If no buyout resolves the case, the court considers the applicable rules for physical division or sale. Under the Act, an open-market sale is required unless the court finds that a sale by sealed bids or auction would be more economically advantageous and in the best interest of the cotenants as a group. The applicable procedure should be assessed before assuming the property will go directly to auction.

How are expenses and sale proceeds allocated?

The deed’s ownership percentages are an important starting point, but the final distribution may require an accounting. Co-owners may dispute mortgage payments, property taxes, necessary repairs, improvements, or rental income collected by one owner.

Gather records supporting each payment and receipt. An owner who paid more than their share may have a reimbursement claim, but not every expenditure produces a dollar-for-dollar credit. Improvement claims can depend on added value rather than cost alone. Occupancy-related claims also depend on facts such as exclusion, agreements, and competing contribution claims.

Liens, sale expenses, and litigation costs can reduce the amount available for distribution. Under Code of Civil Procedure section 874.040, the court generally apportions partition costs in proportion to the parties’ interests or makes another equitable allocation. In an action governed by the Partition of Real Property Act, however, section 874.323 prohibits apportioning partition costs, including appraisal fees, to a party opposing partition unless doing so is equitable and consistent with the Act’s purposes. Recoverable costs can include qualifying attorney fees incurred for the common benefit; that does not mean every party’s entire legal bill will be shared.

What should co-owners do before filing?

Start with a practical assessment of the property’s value, secured debt, potential claims, and available cash for a buyout. Collect the deed, agreements, loan statements, tax records, leases, and payment documentation.

A negotiated buyout, agreed sale, or mediation may avoid some litigation expense. Any settlement should address valuation, payment deadlines, financing, title transfer, releases, and existing loan obligations. Transferring ownership alone does not necessarily release a borrower from mortgage liability. If negotiations fail, these preparations can help clarify the issues for court.
