New York Squatter Laws : Legal Guide to Possession and Eviction

Trespass and adverse possession are not the same thing. A trespasser enters property without permission and has no legal claim to it; an adverse possessor occupies land openly for a statutory period and may eventually acquire legal title. New York Penal Law Section 140.05 defines criminal trespass, which applies when someone knowingly enters or remains on property without permission. The distinction matters because a property owner's remedies depend on which category the occupant falls into.

In practice, these cases are rarely as clean as the statute suggests. Someone may occupy a vacant building for weeks claiming they were invited by a previous tenant, or they may argue the property was abandoned. Courts evaluate the specific facts: whether locks were changed, whether utilities were on, and whether the person paid any rent or property taxes. These details determine whether the case proceeds as a criminal trespass, a civil eviction, or potentially an adverse possession claim.

Removing an unauthorized occupant requires following strict court procedures. The process begins with service of a notice to quit, which gives the occupant a specific period (typically 3 to 30 days depending on the reason for eviction) to vacate. If the occupant does not leave, the property owner files an eviction action in Housing Court (for residential properties) or Supreme Court (for commercial or complex cases). The court issues a judgment and, if necessary, a warrant of eviction that allows the sheriff to physically remove the occupant.

From a practitioner's perspective, timing and proper documentation are everything. Property owners who delay or fail to serve notice correctly often find their cases dismissed and must start over. A single procedural error can add months to the process.

When an occupant has remained on property for several years, they may attempt to claim adverse possession rather than defend against eviction. This claim shifts the legal ground entirely. The occupant must prove all four elements: (1) open and notorious occupation, (2) exclusive possession, (3) continuous occupation for 10 years, and (4) hostile possession without the owner's permission. Courts scrutinize each element carefully. Interruptions in occupancy, payment of rent to the owner, or permission granted by the owner all defeat the claim.

Property owners defending against adverse possession claims often argue that the occupant's presence was permissive or that the occupancy was interrupted. For example, if a property owner allowed someone to stay temporarily during a housing crisis, that permission defeats the hostile element even if the occupant later remained beyond the agreed period. Documenting any communication with the occupant, written notices to vacate, or evidence of the owner's continued assertion of rights strengthens the owner's position.

Beyond civil eviction, unauthorized possession can trigger criminal charges. New York Penal Law Section 140.05 makes criminal trespass a misdemeanor. A property owner can contact police and file a complaint. However, police response varies; officers may decline to intervene in what they perceive as a landlord-tenant dispute rather than a pure trespass. This is where the distinction between a tenant with a lease and a squatter becomes important. A person with a lease has legal possession rights; a squatter does not.

In a real case handled in Queens Criminal Court, a property owner discovered someone living in a vacant commercial space. The owner called police, but the occupant claimed a family member had given permission. The case proceeded through criminal court as a trespass charge, but without clear evidence that the family member lacked authority to grant permission, the charge was difficult to prove. Simultaneously, the owner filed a civil eviction, which moved faster and resulted in removal within months. The criminal case eventually was dismissed, but the civil action achieved the owner's goal.

Early intervention is critical. The longer an occupant remains on the property, the stronger their potential adverse possession claim becomes, and the more difficult removal becomes. Property owners should act within the first few months of discovering unauthorized occupation. Consult with counsel to determine whether the situation involves criminal trespass, a civil eviction, or a potential adverse possession defense that requires different litigation strategies.

Consider whether the occupant may have a colorable claim to possession. If someone has occupied the property for five years openly, the adverse possession risk is significant. If occupancy is recent and clandestine, eviction is more straightforward. Documenting your ownership, your efforts to maintain the property, and your assertion of rights throughout the occupancy period all matter in court. Additionally, understand that drug possession charges may arise if the squatter is using the property for illegal activity, and that criminal and civil remedies may proceed in parallel. Finally, evaluate whether the occupant's underlying circumstances (homelessness, family emergency, mental health crisis) warrant a negotiated resolution rather than full litigation, as courts sometimes favor voluntary departure agreements over contested evictions.
