Partition Action New York: Forcing the Sale of Inherited or Jointly Owned Property

Quick answer

Can one owner force the sale of a jointly owned or inherited house in New York? Yes. Under RPAPL Article 9 any co-owner of New York real property can file a partition action. If the house cannot be fairly divided in pieces, the court can order it sold and the net proceeds split by fractional interest. When the property is inherited, RPAPL section 993 (the Uniform Partition of Heirs Property Act) adds protections: a mandatory settlement conference, an independent court appraisal, a right of first refusal so other co-owners can buy out the selling co-owner at fair market value, a preference for partition in kind where workable, and an open-market sale through a licensed broker if a sale is ultimately ordered.

Why partition actions are rising on Long Island

Home prices on Long Island have climbed past the point where most adult children, siblings, or former partners can simply write a check to buy each other out. When parents leave a Nassau or Suffolk house to several children, or when an unmarried couple bought together and split up, one co-owner usually wants to sell and another wants to keep the house. Without a written agreement to break the tie, the dispute lands in partition.

A partition action is the statutory mechanism New York gives co-owners to exit a property they cannot agree about. It is not a punishment of the other owner and does not require proving fault. It is a property right.

Can one owner force the sale of a jointly owned house in New York?

Yes. RPAPL section 901 gives any person holding real property as a joint tenant or tenant in common the right to maintain an action for partition. The court first decides each owner's fractional interest, then decides whether the property can be physically divided (partition in kind) or must be sold (partition by sale), and finally directs distribution of the net proceeds according to those interests, adjusted for contribution and credits.

For a single-family house, physical division is almost never practical, so the action usually ends in a court-ordered sale. The non-selling co-owner cannot block the sale outright; the question becomes how the sale is conducted and how the money is divided.

What is the difference between partition by sale and partition in kind?

Partition in kind is a physical division of the land. It works for raw acreage that can be subdivided into roughly equal parcels of comparable value. New York courts prefer it where feasible because each owner keeps real property rather than cash.

Partition by sale is a court-ordered sale of the whole property, with the net proceeds distributed by fractional interest after deducting costs, liens, and any contribution credits the court awards. For a single house on a single lot, sale is the default outcome because you cannot fairly cut a house in half.

Under RPAPL 993, when the property is heirs property, the court must lean harder toward partition in kind and may only order a sale when in-kind division would cause great prejudice to the co-owners as a group.

How does the Uniform Partition of Heirs Property Act protect heirs?

New York enacted the Uniform Partition of Heirs Property Act as RPAPL section 993, effective December 6, 2019. It applies when the court finds the real property is heirs property, defined as property held as tenants in common where there is no written agreement governing partition, one or more co-tenants acquired title from a relative, and a threshold portion of the interests are held by relatives. The statute covers residential and certain agricultural property.

When the property qualifies, RPAPL 993 changes the procedure in important ways:

• Mandatory settlement conference. The court holds a settlement conference before commissioners or appraisers are appointed.
• Independent court appraisal. The court orders a disinterested appraisal of fair market value, with an opportunity to object and a court ruling on disputes.
• Right of first refusal and buyout. Co-owners who do not want to sell may buy out the interest of the co-owner who filed the partition action at the court-determined fair market value, in proportion to their existing fractional interests. This is the single most important protection: instead of the family losing the house, the staying co-owners can purchase the leaving co-owner's share.
• Preference for partition in kind. Even if some co-owners want a sale, the court must consider in-kind division and the statutory factors, including sentimental and ancestral ties, length of ownership, use of the property, and any lawful use that would be impaired by a sale.
• Open-market sale at fair market value. If a sale is ultimately ordered, RPAPL 993 generally requires an open-market sale through a licensed real estate broker at the court-determined fair market value, not a courthouse auction. Auctions tend to produce fire-sale prices; open-market sales protect equity.

New York's Heirs Property Protection and Deed Theft Prevention Act of 2024 tightened these protections further against speculators who target a single heir, buy a small fractional interest at a discount, and then file a partition by sale to force a below-value liquidation that wipes out the family's equity.

Can I buy out my siblings instead of selling?

Yes, and it is usually the better path when one co-owner wants to keep the house.

If the property is heirs property under RPAPL 993, the buyout is built into the statute. After the court sets fair market value, the co-owners who do not want to sell get a court-supervised window to elect to purchase the selling co-owner's interest at that value, with the price paid into court and the deed transferred by court order.

If the property is not heirs property, a buyout is still common. It is negotiated by the parties, usually with an agreed independent appraisal, and the partition action is discontinued once the buyout closes. A buyout almost always nets the staying co-owner more equity than a forced sale, because it avoids brokerage fees, the referee's commission, and the litigation costs that come out of the sale proceeds.

What are the defenses to a partition action?

There is no defense to a properly pleaded partition action by a true co-owner of a property without a written agreement to the contrary. The real fights are about ownership shares, contribution, and procedure:

• Challenging the claimed fractional interest. If the deed, will, or trust does not give the plaintiff the share they claim, the court must correct the math before any sale.
• Asserting heirs property status. If the property qualifies under RPAPL 993, asserting that status triggers the buyout, appraisal, and open-market sale protections described above, and changes the leverage.
• Contribution and credit claims. A co-owner who paid more than their proportionate share of property taxes, the mortgage, hazard insurance, or necessary repairs may claim a credit against the other owners' shares from the sale proceeds. Discretionary improvements that add value can also be claimed, though courts scrutinize them.
• Ouster. If one co-owner has been excluded from the property by the other, the excluded owner may claim the fair rental value of the property against the occupying owner.
• Written agreement barring partition. A recorded written agreement among the co-owners not to partition for a defined period is enforceable. Cohabitation and shareholder-style agreements sometimes contain these clauses.

How long does a partition action take in New York and what does it cost?

It depends on the facts. A negotiated buyout that resolves shortly after the complaint is filed can be over in a few months. A contested partition with appraisal fights, contribution claims, and a court-ordered sale through a referee typically runs twelve to twenty-four months, and longer when the heirs property procedure is invoked because of the added settlement conference, appraisal, and buyout windows. Cases on Long Island move at the pace of the Nassau and Suffolk Supreme Court calendars.

The usual costs include the filing fee, title and lien searches, an independent appraisal, the referee's fee (often a percentage of the sale price, fixed by court order), brokerage commission on an open-market sale, and the parties' attorneys' fees. Most of these costs are paid out of the sale proceeds before distribution, which reduces the net for everyone. No attorney can promise an outcome. What experienced counsel can do is structure the case so the protections of RPAPL 993 are actually invoked, the appraisal is contested where appropriate, and contribution credits are properly documented.

How partition fits with other New York real estate disputes

Partition often overlaps with other claims. A co-owner may need a quiet title action first to fix a clouded deed or a missing heir before partition can proceed. Where the property is in foreclosure, partition issues can affect who controls the surplus money after the foreclosure sale. And general real estate disputes, including boundary, easement, and contract issues, sometimes get folded into a partition complaint.
