Partition Action: How Co-Owners Force a Sale and Where Investors Fit

A partition action is a lawsuit in which one co-owner of real estate asks a court to end the co-ownership, either by physically dividing the property or, far more often for a house, by ordering it sold and splitting the proceeds. Any co-owner can usually file one, even if the others want to keep the property, which makes partition the legal backstop behind almost every stalled sale among siblings, ex-partners and business co-owners.

Investors care about partition for two reasons. First, co-owners who disagree are some of the most motivated sellers in any market, and the threat or reality of a partition action is often what brings everyone to the table. Second, buying from co-owners, or buying a fractional interest, has legal traps that do not exist in a normal purchase. This guide covers how partition works, what it costs, how the rules shift by state, and how investors can help co-owners reach a sale without ending up in the middle of a family lawsuit.

Who can file a partition action

Partition is available to people who hold title together as tenants in common or joint tenants. Florida’s statute is typical: Florida Statutes chapter 64 lets one or more joint tenants, tenants in common or coparceners sue their co-owners for partition. California, New York, Texas and most other states have similar rules.

There are important limits:

• Married couples holding as tenants by the entirety generally cannot partition while married in the states that recognize that form of ownership. The issue usually gets resolved in the divorce instead, which is why our guide to divorce real estate leads matters here.
• Written agreements can waive or limit partition. LLC operating agreements, tenancy-in-common agreements and some estate plans restrict the right.
• Life estates and remainders are not co-ownership in the same sense. A remainder owner usually cannot force a partition against a life tenant’s present right to occupy. Our life estate guide explains why.

How a partition action works, step by step

Procedures vary, but most partition cases follow the same arc:

1. Complaint and lis pendens. The co-owner files suit naming every other owner and anyone else with a recorded interest, such as lenders. A lis pendens is often recorded, putting the world on notice.
2. Title and ownership shares. The court determines who owns what. This step can take months if an owner has died without probate or ownership was never clearly recorded.
3. Partition in kind or by sale. Courts historically preferred physical division, but a single-family house cannot be split, so the court usually orders a sale.
4. Referee or commissioner. The court appoints someone to manage the sale, which may be an auction or, increasingly, a broker-listed sale.
5. Accounting. Before proceeds are split, the court sorts out credits and charges: who paid the mortgage, taxes and insurance, who made improvements, and whether anyone who lived there owes rent to the others.
6. Distribution. Liens are paid, partition costs are deducted, and the remainder is divided according to ownership and the accounting.

A contested partition commonly takes many months and can run a year or longer, especially where title has to be cleared first.

What a partition action costs

Partition is not free, and the cost is one of the best arguments for a negotiated sale. California law is a good illustration. Under California Code of Civil Procedure § 874.010, the costs of partition include reasonable attorney’s fees incurred for the common benefit, the referee’s fees and expenses, surveyor charges and the cost of a title report. Under § 874.040, the court generally apportions those costs among the parties in proportion to their interests. Florida’s chapter 64 similarly requires each party to pay a share of costs, including attorney fees, in proportion to its interest, and lets the court pay them from sale proceeds.

So the co-owner who refused to sell often ends up paying part of the lawyer bill for the lawsuit that forced the sale, in addition to their own lawyer. On top of that, a court-ordered auction can bring less than a well-marketed sale. Everyone has an incentive to settle.

Heirs property and the Uniform Partition of Heirs Property Act

The most common partition scenario investors see is inherited property owned by several relatives, often called heirs property. Historically, a single relative, or an investor who bought one relative’s small share, could force a sale of the whole property at a low auction price. That practice caused widespread land loss, particularly among Black families in the South, and led to the Uniform Partition of Heirs Property Act.

Roughly two dozen jurisdictions have adopted the act since Nevada first did in 2011, including Texas, New York, Florida, Virginia and California, and more states continue to consider it. Florida’s version, in sections 64.201 to 64.214, applies to partition actions filed on or after July 1, 2020. Where it applies, the act typically requires:

• A court-determined value, usually based on an independent appraisal, which any co-owner can challenge.
• A buyout right. Co-owners who did not ask for a sale can buy out those who did at that value. Testimony from the Uniform Law Commission to the Rhode Island legislature in 2026 describes a 45-day election window followed by 60 more days to arrange financing.
• A preference for partition in kind if no buyout happens, unless division is impractical or would greatly prejudice the owners.
• An open-market sale through a broker at no less than the court-set value, with an auction only if the court finds it more advantageous.

The act only applies to property that meets its definition of heirs property, which generally means no written agreement among the co-owners and a significant share held by relatives. Each state’s version has its own details. Our heirs property guide covers clearing title on inherited homes before any of this begins.

For investors, the takeaway is simple: in states with the act, buying one heir’s interest and forcing an auction is no longer a reliable strategy, and it was never an ethical one. The modern approach is to help the family reach a voluntary sale of the whole property.

Partition rules vary by state

Issue	Where it varies	Why investors care
Heirs property protections	Applies only in states that adopted the uniform act, and only to qualifying property	Determines whether co-owners get buyout rights and an open-market sale
Cost and fee allocation	California and Florida apportion costs, including attorney fees, by interest; other states differ	Affects each owner’s net and their willingness to settle
Sale method	Auction, referee sale or broker listing depending on the state and court	Auction sales can create buying opportunities, but also low prices for the family
Credits for payments and improvements	Rules on mortgage, tax, insurance and improvement credits differ	Changes how the proceeds split, and who is motivated to settle
Waiting periods and mediation	Some courts require mediation or settlement conferences	Adds time but often produces the negotiated sale

Check the rules for your market in our state-by-state guides, and expect the details to come from a local real estate litigation attorney.

Alternatives co-owners should consider first

A partition action is rarely the first choice, and it should not be presented as one. Before anyone files, co-owners usually have several options:

Option	How it works	Best when
Internal buyout	One owner buys the others’ shares, often with a cash-out refinance or private loan	One owner wants to keep the property and can finance it
Listing with an agent	All owners agree to list and split the net proceeds	The house shows well and the owners can wait for a retail buyer
As-is sale to an investor	All owners sign one contract with a cash buyer	The house needs work, an owner needs speed, or the owners want certainty
Mediation	A neutral helps the owners agree on price, timing and credits	Communication has broken down but no one wants a lawsuit
Partition action	A court divides the property or orders it sold	Every voluntary option has failed

An honest investor conversation covers all five. Owners who feel informed are far more likely to choose your offer, and far less likely to back out later.

How partition leads show up

Partition situations surface in a few predictable places. Partition complaints are public civil court filings, so some investors monitor court dockets for new cases, though once a suit is filed you should expect to deal through the owners’ attorneys. Inherited properties with several heirs appear in probate records long before anyone sues. Divorce filings, tax-delinquent lists and vacant-property lists often overlap with co-owned houses where no single owner is taking responsibility. Stacking those signals is usually more productive than waiting for a lawsuit.

Where investors fit in a partition situation

There are three common roles, and only one of them is usually a good idea for a beginner.

Buying the whole property from all co-owners

This is the cleanest deal. Every owner signs the purchase agreement, title is delivered by all of them, and the proceeds are split at closing according to their agreement or ownership percentages. Your value is speed, certainty and an as-is purchase that avoids the cost and delay of a lawsuit. The hard part is getting everyone to agree, and that is usually a people problem rather than a price problem.

Buying out one co-owner’s interest

Some investors buy a fractional interest from a co-owner who wants out. This is legal in most places, but it is a specialty strategy. You become a co-owner with people you do not know, you may have no right to occupy or rent the property without them, and if you then file for partition, heirs property protections, cost allocation and a court’s sense of fairness can all work against you. Do not do this without a local attorney and a clear exit.

Buying at a court-ordered sale

When partition ends in an auction or referee sale, investors can bid like at any other judicial sale. Understand whether the sale is subject to court confirmation, what liens survive, and what due diligence is possible. Our guide to how foreclosure auctions work covers many of the same mechanics.

Worked example: three siblings and one house

The figures below are hypothetical, built to show why a negotiated sale usually beats a lawsuit.

Three siblings inherit a house equally. One lives in it rent-free; the other two want to sell. The house is worth about $300,000 as-is, with a $40,000 reverse mortgage balance. The two selling siblings talk to a partition attorney, who estimates that a contested case through sale would take 12 to 18 months.

Scenario	Sale price	Liens	Estimated costs	Net to split	Each sibling’s one-third share
Voluntary as-is sale to an investor	$270,000	$40,000	$8,000 closing costs	$222,000	$74,000
Partition with broker listing	$300,000	$40,000 plus about $5,000 of accrued interest	$18,000 commission and closing costs, plus $45,000 combined legal and referee costs	$192,000	$64,000

The partition figures assume higher costs and a year of delay, which in practice varies widely. Even with a higher sale price, the siblings may net less through the lawsuit. And the sibling living in the house may also face an accounting claim for rent. That comparison, shown honestly and with the family’s own attorney or advisor involved, is often what produces a signed contract.

Notice what the investor is doing here: presenting a clear alternative, not pushing one sibling against the others. If the voluntary sale nets less than a well-marketed listing would, the right move may be to suggest listing the property with an agent.

How to approach co-owners about a sale

• Talk to every owner. A contract signed by one co-owner cannot sell the whole property. Pull title to identify every owner of record and skip trace each one.
• Stay neutral. You are not anyone’s advocate in the family dispute. Offer the same information to everyone.
• Show the numbers. A simple net sheet for each owner, like the one in our seller net sheet guide, is more persuasive than any script.
• Recommend independent advice. If a partition suit is filed or threatened, each owner should have their own attorney, and you should expect to work through them.
• Respect the occupant. If one owner lives in the house, plan for a reasonable move-out timeline and, where appropriate, relocation help such as cash for keys.

When partition deals are the wrong move

• Title is not settled. If an owner died and the estate was never probated, the first step may be probate or a quiet title action, not a purchase contract.
• One owner is unreachable or incapacitated. You may need a guardian, conservator or court involvement before anyone can sign.
• The family is already in litigation. Once lawyers are involved, any deal goes through them and often needs court approval.
• You would profit only by buying a small share cheaply and forcing a sale. Besides heirs property protections, this damages your reputation in exactly the communities where these leads come from.

Partition action FAQ

Can a co-owner force the sale of a house?

In most states, yes. Absent a written agreement waiving partition or a special form of ownership like tenancy by the entirety, a co-owner can ask a court to partition the property, and for a house that usually means a court-ordered sale.

How long does a partition action take?

A partition action settled early can resolve in a few months. A contested case that requires title clearing, an accounting and a court-supervised sale commonly takes a year or more.

Who pays the attorney fees in a partition action?

It depends on the state. In California and Florida, costs that benefit everyone, including certain attorney fees, are generally apportioned among the owners in proportion to their interests. Other states follow different rules.

Can I buy a house from just one of the heirs?

You can buy that heir’s share, but not the whole property. To buy the whole house, every owner, or their legal representative, must sign.

Can an investor who owns a fractional interest file a partition action?

Usually, yes, because the investor is now a co-owner. But courts weigh fairness, heirs property protections may give the family a buyout right at the appraised value, and partition costs come out of everyone’s share, including yours. Many fractional-interest investors end up negotiating rather than litigating.

Does partition wipe out the mortgage?

No. Liens are paid from the sale proceeds before the owners split what remains.

A partition action is the tool of last resort for co-owners who cannot agree. For investors, it is mostly a reason co-owners decide to sell. Learn the rules in your state, work with every owner fairly, and you can solve a real problem for a family without ever setting foot in the courtroom.
