Short answer: a partition action is a lawsuit that asks a court to divide jointly owned property when the co-owners cannot agree what to do with it. In New York, any co-owner holding as a tenant in common or joint tenant can bring one under Real Property Actions and Proceedings Law Article 9. Because most homes cannot be physically divided, courts usually order the property sold and the proceeds split.
Partition disputes often arise between siblings who inherit a house, unmarried partners who bought together, or investors who disagree about selling. A partition action is usually the last resort: it is slow and expensive, and most co-owners are better served by negotiating a buyout or sale. Knowing how the process works gives you leverage in that negotiation.
Who Can Bring a Partition Action in New York?
Under RPAPL §901, a person who holds property as a joint tenant or tenant in common with others can seek partition. There are important limits:
- Married couples. Spouses who own as tenants by the entirety cannot force a partition while they are married; the property is dealt with in the divorce instead.
- Agreements. A co-ownership or operating agreement that waives partition or requires a buyout first can limit or delay the right.
- Co-ops and LLCs. Co-op shares and property held through an LLC are divided under different rules, not a real property partition.
How a Partition Action Works
| Stage | What happens |
|---|---|
| 1. Complaint | The co-owner files in Supreme Court in the county where the property is, naming every co-owner and anyone with a lien, and files a notice of pendency. |
| 2. Ownership determination | The court determines each owner’s share, often with the help of a referee. |
| 3. Partition in kind or sale | The court decides whether the property can be physically divided without great prejudice. For a single house or apartment building, it almost always orders a sale. |
| 4. Sale | A referee typically conducts the sale, often at public auction unless the parties agree otherwise. |
| 5. Accounting and distribution | Proceeds are divided by ownership share after costs, with adjustments for items such as one owner paying more of the taxes, mortgage or repairs, or living in the property exclusively. |
A contested partition can take many months or longer, and the costs of the referee, sale and litigation reduce what everyone receives. A public auction can also bring a lower price than a negotiated market sale.
Inherited Property and the Heirs Property Law
Since 2019, New York has given extra protection to “heirs property”: property inherited by relatives without a will or agreement governing co-ownership. Under RPAPL §993, the court must order an appraisal, give the other co-owners a chance to buy out the co-owner seeking partition at the appraised value, and consider dividing the property before ordering a sale. If a sale is needed, it is generally an open-market sale through a broker rather than an auction. These protections were designed to prevent families from losing inherited homes at below-market prices.
Alternatives to a Partition Lawsuit
- Buyout. One co-owner buys the others’ shares, usually based on an appraisal. The deed transfer is often done with a bargain and sale or quitclaim deed.
- Negotiated sale. The co-owners agree to list the property and divide the proceeds, avoiding court costs and auction discounts.
- Mediation. A neutral mediator helps co-owners reach a buyout or sale agreement, often faster and more cheaply than litigation.
- Co-ownership agreement. For future purchases, a written agreement that sets buyout rights and a valuation method prevents most partition disputes.

Frequently Asked Questions
What is a partition action in New York?
A partition action is a lawsuit, brought under RPAPL Article 9, asking a court to divide co-owned real property. The court either physically divides it or, far more often, orders it sold and splits the proceeds among the owners.
Can a co-owner force the sale of a house in New York?
Generally yes. A tenant in common or joint tenant can bring a partition action, and if the property cannot be fairly divided, the court can order a sale even if the other owners object. Spouses owning as tenants by the entirety cannot force partition while married.
How long does a partition action take in New York?
A contested partition commonly takes many months and can take longer, depending on the court, the number of owners and whether ownership shares or credits are disputed. A negotiated buyout or sale is usually much faster.
What is heirs property in New York?
Heirs property is real estate inherited by relatives without a will or agreement governing co-ownership. Under RPAPL §993, partition of heirs property requires an appraisal, a buyout opportunity for the other co-owners and a preference for dividing the property before selling it.
Who pays the costs of a partition action?
Court, referee and sale costs are generally paid from the sale proceeds before distribution, which reduces what every owner receives. Each party usually pays its own attorney unless the court orders otherwise.
