Partition Actions in Los Angeles: How Co-Owners Force a Sale

If you co-own real estate in Los Angeles and the other owner refuses to sell, or refuses to buy you out, California law gives you a powerful remedy: a partition action. In most cases, a co-owner has the right to ask the court to order the property sold and the proceeds divided, even over the other owner's objection. Here is how partition works in Los Angeles County, what it costs, how long it takes, and the alternatives worth exploring first.

What is a partition action?

A partition action is a lawsuit asking a judge to end a co-ownership. It is filed in the Superior Court for the county where the property sits, which for Los Angeles property means the Los Angeles Superior Court. The court can divide the property physically, order it sold with the proceeds split, or allow one owner to buy the other out at an appraised value under a relatively recent change in California law.

Partition disputes arise constantly in Los Angeles: siblings who inherited a family home and disagree about keeping it, unmarried couples who bought a house together and split up, friends or relatives who invested in a property with no written agreement, and business partners holding investment real estate after the partnership sours.

Who can file, and can the other owner stop it?

Generally, any co-owner may seek partition, whether they hold title as a tenant in common or as a joint tenant. California treats the right to partition as a fundamental incident of co-ownership. A co-owner ordinarily cannot be forced to remain in a co-ownership they want to leave.

That said, the right is not unlimited. Co-owners can waive or restrict partition by agreement, and many co-ownership and TIC agreements do exactly that. The defenses available in a particular case depend on its facts. If you signed anything governing the property with your co-owner, have an attorney review it before you file.

The three forms of partition

1. Partition by sale. The property is sold and the net proceeds are divided according to each owner's interest and the court's accounting. This is the most common outcome for homes and other improved property in Los Angeles, where physically splitting the land is impracticable.
2. Partition in kind. The property is physically divided. Courts favor this in theory, but it is realistic mainly for raw land.
3. Partition by appraisal or buyout. One owner acquires the other's interest at a value fixed by appraisal, either by agreement or under the statutory buyout procedure described below.

The 2023 change every co-owner should know about

For partition actions filed since 2023, California's Partition of Real Property Act changed the playing field for many co-owned properties. In qualifying cases, typically tenants in common with no binding partition agreement, a co-owner who did not ask for partition generally has a right to buy out the filing co-owner's interest at a court-determined appraised value before the property is ordered sold.

Practically, this means two things. If you are the co-owner seeking partition, you may end up with a buyout at appraised value rather than a market sale. If you are the co-owner resisting a sale, for example because you live in an inherited family home, the Act may give you a realistic path to keep the property. Either way, the appraisal and the strict statutory deadlines become the battleground, and experienced counsel matters.

How a Los Angeles partition case actually proceeds

1. Complaint and lis pendens. The case begins with a complaint identifying the property and the owners' interests. A lis pendens (notice of pending action) is recorded against title, which effectively prevents a sale or refinance while the case is pending. See our guide to how a lis pendens works in California.
2. Interlocutory judgment. The court determines that the plaintiff has a right to partition and fixes each owner's percentage interest. Disputes about title or ownership shares are resolved here, sometimes alongside a quiet title claim. See quiet title actions between co-owners.
3. Buyout window or referee. In qualifying cases, the statutory buyout procedure runs first. Otherwise, or if no buyout happens, the court appoints a neutral referee to manage the division or sale, often through an open-market listing.
4. Accounting and offsets. Before proceeds are divided, the court accounts for the co-ownership. A co-owner who paid more than their share of the mortgage, property taxes, insurance, or necessary repairs can seek credits. Rents collected from the property and, in some circumstances, the value of one owner's exclusive use may also be charged. This accounting frequently moves as much money as the ownership percentages themselves.
5. Distribution. The referee's sale is confirmed, costs are paid, and the net proceeds are distributed per the judgment.

Who pays the attorneys and costs?

California law treats the reasonable costs of partition, including attorney's fees incurred for the common benefit of the owners, as chargeable against the property and apportionable among the parties by the court. Fees spent purely fighting your co-owner, rather than advancing the partition itself, are typically each side's own burden. This cost-shifting framework is one more reason partition cases so often settle once both sides understand it.

How long does it take?

An uncontested partition that settles into a buyout can wrap up in a few months. A contested case in the Los Angeles Superior Court, with disputed ownership shares, accounting fights, or a contested referee sale, commonly runs a year or more. The single biggest driver of both cost and time is how early the parties get realistic about the endgame.

Before you file: the alternatives

Most co-ownership disputes should start with a demand and a negotiation, not a filing. A negotiated buyout at a price informed by a broker opinion or appraisal, a voluntary sale with an agreed split, or mediation can achieve in weeks what litigation achieves in a year. Filing a well-prepared partition action often becomes the leverage that makes those talks succeed. An attorney can position you so that either path works.
