Partition Actions: Forcing the Sale of Co-Owned California Property

When co-owners of a California property can’t agree on whether to sell, a partition action is the legal remedy. Here is how the process works and how a neutral sale gets everyone paid.

Direct AnswerA partition action is a California lawsuit that lets any co-owner of real property force its division or sale when the owners cannot agree. Most homes cannot be physically divided, so courts typically order a “partition by sale,” with proceeds split according to each owner’s interest. California’s Partition of Real Property Act (Code of Civil Procedure § 874.311 et seq., building on the older § 872.210 framework) adds buyout rights and appraisal-based procedures designed to protect co-owners and favor open-market sales.

When a partition action applies

Common triggers include inherited property where heirs disagree, a breakup of unmarried co-owners, or investment partners at an impasse. Any co-owner generally has the right to seek partition — you cannot be forced to remain a co-owner indefinitely.

Partition by sale and co-owner buyout

Because dividing a single-family home is usually impractical, courts order a sale. Under the modern Partition of Real Property Act, the court typically obtains an appraisal and offers non-petitioning co-owners the option to buy out the petitioning owner’s share before any open-market sale — a process meant to keep families and partners whole.

Why a neutral broker matters

When the court orders an open-market sale, it often appoints a referee and a real-estate broker to run it neutrally. A broker experienced in court-supervised and contested sales protects value, documents the process, and keeps the transaction defensible for all parties.
