Owning real estate with someone else can work well for years — until it doesn’t. A vacation home inherited by siblings, a house purchased by an unmarried couple, or an investment property held by friends can all reach the same breaking point: one owner wants out, another wants to keep the property, and no one agrees on what happens next.
That is where a partition action often enters the picture.
A partition action is a court process that can separate co-owners’ interests in real estate, either by physically dividing the property in limited situations or, more commonly, by ordering a sale and splitting the proceeds according to each owner’s legal interest. Courts and legal commentators regularly describe partition as a core remedy available to cotenants when shared ownership becomes unworkable, although the details vary by state law and by the type of property involved. See, for example, the American Bar Association’s discussion of partition law and heirs’ property protections and recent ABA coverage of partition disputes in probate and family property conflicts.
If you are new to the topic, this can feel intimidating fast. In this post you’ll learn what a partition action is, when it comes up, how the process usually works, what outcomes are possible, and why these cases often become more complicated when inherited property, mortgages, reimbursements, or family conflict are involved. If you want a broader overview of co-owner stalemates, forced sales, buyouts, and inherited-property disputes, this guide also pairs well with our article on what tends to happen when co-owners hit a deadlock over real estate.

A partition action is a lawsuit involving co-owned property. One owner asks the court to end the shared ownership arrangement because the owners cannot agree on whether to keep, sell, divide, refinance, occupy, or improve the property.
In general terms, courts tend to consider a few possible remedies:
This means the property is physically divided into separate portions. This outcome is more common with land that can realistically be split, such as acreage or some rural tracts. It is much less common with a single-family house, condo, or small multifamily building because those properties usually cannot be divided in a practical way.
The historical preference in many statutes has been for partition in kind unless a sale would be more appropriate because division would cause substantial prejudice or injury. The ABA’s overview of the Uniform Partition of Heirs Property Act explains how courts have often struggled with that standard and how modern reforms try to make the analysis more structured.
This means the court orders the property sold and the proceeds distributed among the co-owners after paying liens, sale costs, and any court-approved adjustments. For most residential homes, this is the remedy people think of when they hear “forced sale.”
In some jurisdictions or fact patterns, one co-owner may be allowed to buy out another owner’s interest instead of forcing a sale of the entire property. Recent ABA case commentary notes that some statutes expressly contemplate remedies including partition in kind, partition by sale, or assignment and buyout depending on the circumstances and the governing state law. See the ABA’s 2025 property case update.
Partition actions often appear in a few recurring situations:
A parent dies owning a home, land, or rental property. Several children inherit equal shares. One wants to sell. Another wants to rent it out. A third lives there and cannot afford to buy everyone else out. The property sits in limbo, taxes and insurance continue, and conflict grows.
