Partition Actions & Apartment Buildings in Los Angeles: When Co-Owners Can't Agree

March 4, 2026·6 min read

Understanding CCP §872.210 partition actions for multifamily properties, including partition by sale vs. partition in kind, court-appointed referees, and the Uniform Partition of Heirs Property Act.

When Co-Owners Reach an Impasse

Co-ownership of real estate can work well when all parties agree on strategy—but when relationships deteriorate or goals diverge, the situation can become untenable. California law provides a remedy: the partition action.

This article explains how partition actions work for apartment buildings and other income properties in Los Angeles, the role of court-appointed referees, and what co-owners should know before pursuing this legal remedy.

What Is a Partition Action?

A partition action is a legal proceeding under California Code of Civil Procedure §872.210 that allows co-owners to divide or sell jointly-owned property when they can't agree on what to do with it.

Who Can File for Partition?

Any co-owner can file for partition, regardless of:

  • The size of their ownership interest (even a 1% owner can file)
  • How the co-ownership arose (inheritance, investment, divorce)
  • Whether other co-owners consent

Two Types of Partition

Partition in Kind (Division)

The property is physically divided, with each co-owner receiving a separate parcel. This works for:

  • Large land parcels that can be subdivided
  • Properties with distinct, separable components

Partition by Sale

The property is sold and proceeds divided among co-owners. This is the typical outcome for:

  • Apartment buildings (can't physically divide units)
  • Single structures on single lots
  • Properties where division would destroy value

For apartment buildings, partition by sale is almost always the result because physical division isn't practical.

The Partition Process for Apartment Buildings

Step 1: Filing the Complaint

The co-owner seeking partition files a complaint in Superior Court that:

  • Identifies all co-owners and their interests
  • Describes the property
  • Requests partition by sale (or in kind)
  • May request appointment of a receiver

Step 2: The Interlocutory Judgment

After initial proceedings, the court issues an interlocutory judgment that:

  • Confirms partition is appropriate
  • Orders partition by sale (for apartment buildings)
  • Appoints a referee to conduct the sale

Step 3: Court-Appointed Referee

The referee—typically a real estate professional or attorney—is appointed to:

  • Take possession of the property
  • Manage the property during the sale process
  • List and market the property
  • Accept offers and negotiate terms
  • Report to the court
  • Distribute proceeds after sale

The referee is a neutral party working for the court, not for any individual co-owner.

Step 4: Sale Process

The referee typically:

  • Hires a real estate broker (may be the referee themselves if qualified)
  • Obtains an appraisal or broker opinion of value
  • Lists the property for sale
  • Reviews and accepts offers
  • Seeks court confirmation of the sale

Step 5: Distribution of Proceeds

After the sale closes, proceeds are distributed:

  • Pay referee fees and costs
  • Pay any encumbrances (mortgages, liens)
  • Pay partition costs (attorneys, experts)
  • Distribute remainder to co-owners by ownership percentage

The Uniform Partition of Heirs Property Act (UPHPA)

In 2022, California adopted the Uniform Partition of Heirs Property Act, which provides additional protections when:

  • The property was acquired by co-owners by gift, devise, or intestate succession
  • Co-owners are related or there is evidence of agreement to keep property in the family

UPHPA Protections Include:

Notice Requirements

  • All co-owners must receive proper notice of partition proceedings
  • Notice must include information about rights under UPHPA

Buyout Rights

Before the property is sold, non-partitioning co-owners have the right to buy out the partitioning co-owner's interest at appraised fair market value.

  • Buyout must be at appraised value (not necessarily original asking price)
  • Co-owners have a specified period to exercise buyout right
  • Multiple co-owners can combine to make the buyout

Open Market Sale Preference

If a sale is ordered, UPHPA generally requires sale on the open market (not at courthouse auction) unless the court finds that auction would be more economically advantageous.

Fair Market Value Determination

An appraisal by a licensed appraiser is required, considering:

  • The property's highest and best use
  • Comparable sales
  • Any deferred maintenance or required capital

Why UPHPA Matters for Inherited Property

Before UPHPA, inherited family properties were vulnerable to forced sales at below-market prices. One heir could file for partition, and the property might sell at a courthouse auction for a fraction of its value.

UPHPA ensures:

  • Other heirs can buy out the selling heir at fair value
  • If sold, the property is marketed for maximum value
  • The process is more transparent and protective

How Partition Differs from Co-Owner Negotiated Sales

Voluntary Sale

When co-owners agree to sell:

  • They choose the broker together
  • They approve pricing and marketing strategy
  • They accept offers by consensus
  • No court involvement or referee fees
  • Faster and less expensive

Partition Sale

When partition is necessary:

  • Court appoints the referee
  • Referee controls sale process
  • Court must confirm the sale
  • Significant legal costs for all parties
  • Longer timeline
  • Less control for any individual co-owner

The message is clear: voluntary agreement is almost always better than partition, even if it requires compromise.

Costs of Partition

Partition is expensive. Typical costs include:

Legal Fees

  • Filing co-owner's attorney: $25,000 - $100,000+
  • Responding co-owners' attorneys: Similar amounts
  • Total legal fees: Can easily exceed $100,000 combined

Referee Fees

  • Referees typically charge hourly rates similar to attorneys
  • Plus percentage of sale price in some cases
  • Property management fees during the sale period

Appraisal and Sale Costs

  • Appraisal: $3,000 - $10,000
  • Real estate commission: 4-6% of sale price
  • Closing costs: Standard amounts

Opportunity Cost

  • The property may sell for less than it would with cooperative marketing
  • Rushed timelines may not optimize price
  • Buyer may discount for partition-related uncertainty

For a $5 million apartment building, total partition costs easily reach $300,000 - $500,000 or more—money that comes out of all co-owners' pockets.

Strategies to Avoid Partition

Communication and Mediation

Before filing partition:

  • Have honest conversations about goals
  • Consider mediation with a neutral third party
  • Explore compromise positions

Buyout Negotiation

Often, one co-owner can buy out the other(s):

  • Obtain an independent appraisal
  • Negotiate fair terms
  • Finance the buyout with a cash-out refinance or new loan

Agreed Sale

If all co-owners want to sell but can't agree on terms:

  • Use a neutral broker chosen together
  • Agree on a pricing range
  • Commit to accept any offer within that range
  • Memorialize the agreement in writing

The Broker's Role in Partition Sales

When I work with partition referees or attorneys on partition sales, I provide:

Court-Ready Documentation

  • Detailed Broker Opinion of Value with methodology
  • Comparable sales analysis
  • Marketing plan for referee approval
  • Activity reports for court filings

Professional Marketing

  • MLS and commercial database exposure
  • Targeted buyer outreach
  • Tour coordination despite multiple owner dynamics
  • Offer solicitation and analysis

Neutral Positioning

  • I work for the referee, not individual co-owners
  • Objective advice on offers and pricing
  • No favoritism toward any party
  • Focus on maximizing value for all interests

Timeline Expectations for Partition Sales

  • Filing to interlocutory judgment: 3-6 months
  • Referee appointment to listing: 1-2 months
  • Listing to accepted offer: 2-4 months
  • Court confirmation of sale: 1-2 months
  • Confirmation to close: 1-2 months
  • Total: 8-16 months from filing to distribution

This timeline can be shorter with cooperative parties or longer with contested proceedings.

Partnership Dissolution vs. Partition

If co-owners hold property through an LLC or partnership, the process differs:

  • Partnership/LLC dissolution follows the operating agreement
  • May involve buyout provisions, valuation formulas, arbitration
  • Typically faster and less costly than partition
