A Yellowstone injunction is a New York court order that freezes the cure period in a commercial lease so the landlord cannot terminate the tenancy while a judge decides whether the tenant actually defaulted. The remedy exists because cure periods are short, lease terminations are hard to undo, and a tenant who waits for the courts to sort out the dispute on a normal schedule may lose the leasehold before anyone rules on whether a violation occurred. Freezing the clock is the whole point.
The protection applies to commercial tenants in New York. Courts have occasionally extended similar equitable relief to residential tenants in narrow circumstances, but the classic Yellowstone remedy is a commercial-lease tool.
The Four Things a Tenant Must Show
New York courts require four elements. Miss one and the application fails.
- A valid commercial lease for property in New York.
- A written notice from the landlord, usually a notice to cure or notice of default, that threatens lease termination. This notice is the trigger, and its deadline is what the court will freeze.
- An application for injunctive relief filed before the cure period in that notice expires. This is the hardest requirement to meet and the one that defeats most late applications.
- A genuine willingness and practical ability to cure the alleged default by some means other than vacating. The tenant does not have to admit the violation; they have to show that if one is found, they can and will fix it.
The timing prong is unforgiving. Tenants who wait until the last day of a ten-day cure period to call a lawyer often find there is not enough time to draft the papers, get them in front of a judge, and have an order signed before the deadline runs. Once the cure window closes, the court loses the ability to toll it, and the lease may already be terminated as a matter of law.
When Yellowstone Relief Is Not Available
Some defaults are treated as incurable, and Yellowstone injunctions do not apply to them. If the lease states that a particular violation triggers automatic termination with no opportunity to cure, there is no cure period for the court to freeze. Unauthorized assignment or subletting is the default landlords most often argue is incurable, especially when the lease expressly provides for automatic termination on an improper transfer. Where the tenant has already taken concrete steps to reverse the violation before filing, courts have sometimes granted relief in assignment cases, but the outcome is heavily fact-dependent.
The remedy is also gone once the lease has already been terminated. If the landlord served a notice of termination and the termination date has passed, a Yellowstone motion filed afterward will be denied, and the tenant has to look to other legal theories. The same result follows when a tenant received a predicate notice, did nothing, and let the cure period lapse before going to court.
Getting the Motion on File in Time
Start with the two documents that define the dispute: the commercial lease and the landlord’s notice to cure. Read the notice carefully. Cure periods vary with the lease language and commonly run from ten to thirty days. That number sets the clock for everything that follows.
Then gather evidence that proves the ability to cure. Bank statements showing available funds, written estimates from licensed contractors, updated insurance certificates, and correspondence with regulatory agencies all do this work. The court needs to see that if a default exists, the tenant has the money, access to the trades, or paperwork in motion to put it right.
The motion itself is an Order to Show Cause supported by a detailed affidavit from the tenant or a company officer with direct knowledge. The affidavit lays out the nature of the dispute, explains why the tenant believes no default occurred or why the alleged default is curable, and commits the tenant to preserving the lease and complying with whatever the court orders. There is rarely a chance for live testimony at this stage, so the affidavit does most of the talking.
File in New York Supreme Court in the county where the property is located. The motion should include a request for a Temporary Restraining Order, which freezes the cure period the moment a judge signs it. Most courts have procedures for emergency applications; use them. Once the TRO is signed, serve the landlord or the landlord’s attorney with the signed order and all supporting papers within the window the judge specifies, often twenty-four to forty-eight hours. Service must be completed exactly as the order directs. Late or sloppy service is one of the fastest ways to lose the entire motion.
Between filing and the return date, the TRO holds the cure period open and prohibits the landlord from issuing a notice of termination or starting a summary eviction proceeding in Civil Court. The court then schedules a hearing on the preliminary injunction.
The Money Required to Keep the Injunction in Place
CPLR 6312(b) requires the tenant to post an undertaking before a preliminary injunction can be granted. This is usually a surety bond or a cash deposit with the court, and it protects the landlord from losses sustained during the injunction period if the court later decides the injunction should not have issued. The statute requires the undertaking to cover all damages and costs the landlord may suffer because of the injunction, including reasonable rents and profits from the property and any waste committed after it was imposed.1New York State Senate.

The judge sets the amount. It varies with the monthly rent, the nature of the alleged default, potential property damage, and the estimated cost of professional work needed to cure. A straightforward dispute may require a modest bond. A high-rent commercial space with substantial alleged arrears can draw a bond equal to several months’ rent or more. The undertaking has to stay active for the entire litigation. If it lapses or is never properly posted, the court can vacate the injunction and the landlord regains the ability to terminate.
Courts also routinely condition the injunction on continuing monthly use and occupancy payments, typically set at the rent in the lease. Falling behind on these payments is grounds for dissolving the injunction. Where the dispute itself is about how much rent is owed, courts may require payment of the undisputed portion, direct payments into a court escrow, or, rarely, waive interim payments when the whole rent obligation is genuinely contested. A tenant not making use and occupancy payments should expect the court to require a larger undertaking in exchange.
What Happens Next
A Yellowstone injunction does not decide the dispute. It preserves the lease so the dispute can be decided on the merits in Supreme Court through discovery, motion practice, and potentially trial. That process runs considerably longer than a summary proceeding in landlord-tenant court. The tenant stays in possession and keeps paying use and occupancy throughout.
If the court ultimately finds no default, the cure period resumes or the issue is declared moot and the tenancy continues as before. If the court finds a curable default did occur, the tenant gets a defined period to fix it. Failure to cure within that window lets the landlord proceed with termination.
Denial moves fast in the opposite direction. If the court refuses the injunction and the cure period has already expired, which it almost certainly has by the time of the hearing, the landlord can immediately serve a notice of termination and start a holdover proceeding in Civil Court. New York’s summary eviction process for commercial tenants moves quickly. Once a petition is served and the tenant fails to respond or loses at trial, the court can issue a warrant of eviction, a city marshal serves a notice of eviction, and physical removal can follow within weeks of the judgment. For a business, that often means losing foot traffic, operations, and the value of any improvements made to the space. The strictness of the timing requirements reflects exactly that risk: by the time a tenant realizes they need this protection, the window to get it may already be closing.
