You’re about to sign a contract for the biggest financial transaction of your life. The document sitting in front of you has forty pages of legal language, and you’ve got three days to review it before your attorney review period expires. You skim through clauses about title defects, easements, and disclosure requirements, but honestly—you’re not entirely sure what half of it means. That uncertainty is exactly where expensive mistakes happen. In Long Island, NY, real estate contracts aren’t just paperwork. They’re legal agreements that determine whether you walk away with a clean title or spend the next six years in litigation over problems the seller never disclosed. This breakdown covers the contract mistakes that actually cost people money—and how to catch them before closing.

Hidden Liens That Survive the Sale

Liens don’t disappear when property changes hands. If the previous owner owed money to contractors, the IRS, or the city, those debts can attach to the property itself. You become responsible for clearing them even though you had nothing to do with creating the debt.

Title searches are supposed to catch these issues, but not all liens show up in public records. Some municipalities don’t publish certain violations. Others get filed after your title search but before closing.

The result is the same—you own the property, and now you own the problem. This is why working with a real estate attorney who understands title issues makes a difference in protecting your investment.

Types of Property Liens Common in Long Island Real Estate

Mortgage liens are the most obvious. If the seller hasn’t paid off their mortgage, that lien stays on the property until it’s satisfied. Most closings handle this automatically, with the seller’s mortgage payoff coming out of sale proceeds.

Tax liens are more problematic. When property owners don’t pay real estate taxes, the county or town files a lien. These take priority over almost everything else. You can’t get clear title until they’re resolved.

Mechanic’s liens come from unpaid contractors or suppliers who worked on the property. New York law allows contractors to file these liens if they don’t get paid for labor or materials. The tricky part is timing. A contractor might file a lien weeks after you’ve already signed a contract, but before closing.

Judgment liens result from court cases. If someone sued the previous owner and won, they can file a judgment lien against any property that person owns. These liens follow the property, not the person.

Municipal liens cover everything from unpaid water bills to code violations. Long Island properties can have liens for sidewalk repairs, environmental violations, or building code issues. Some of these are small. Others run into tens of thousands of dollars.

The real problem with liens isn’t just the money. It’s the delay. Clearing a lien takes time. You need documentation showing it’s been paid or released. You need the lienholder to file the proper paperwork with the county. If the lienholder is difficult to locate or uncooperative, your closing date gets pushed back.

If you’ve already given notice to your landlord or sold your current home, that delay creates serious problems. We review title reports specifically to catch these issues before they derail your closing timeline.

Disclosure Violations and Easement Disputes

New York requires sellers to disclose known defects that materially affect the property’s value. Starting in March 2024, sellers can no longer avoid this requirement by paying a $500 credit to the buyer. They must complete a Property Condition Disclosure Statement, and if they lie or leave out important information, buyers can sue them even after closing.

The statute of limitations on these claims runs up to six years. That means a seller who fails to disclose a foundation problem or a roof defect can face a lawsuit years after the sale. Easement issues add another layer of complexity—they affect how you can use your property, and many buyers don’t discover them until after closing.

These problems require representation from a real estate litigation attorney who understands both disclosure law and property rights disputes in New York.

What New York Sellers Must Disclose About Property Condition

The Property Condition Disclosure Statement asks 48 questions about the property’s condition. Sellers must answer based on their actual knowledge at the time they complete the form. The questions cover structural issues, mechanical systems, environmental hazards, legal matters, and more.

Structural disclosures include foundation problems, roof condition, water damage, and pest damage. If the seller knows the basement floods every spring or the roof leaks when it rains hard, they must disclose it.

Mechanical system questions cover heating, cooling, plumbing, and electrical systems. Sellers must disclose if systems don’t work properly or if there are known defects. A furnace that frequently breaks down or has a cracked heat exchanger absolutely requires disclosure.

Environmental disclosures cover lead paint, asbestos, radon, underground storage tanks, and contamination. Properties built before 1978 require separate federal lead paint disclosures. Sellers must also disclose if the property is in a flood zone.

Legal and zoning disclosures include easements, boundary disputes, zoning violations, and pending legal actions affecting the property. If the neighbor has a right to cross your property to reach their driveway, that’s an easement the seller must disclose.

The disclosure form specifically asks about shared driveways, party walls, and encroachments. These issues are common in Long Island, NY, where properties sit close together and driveways often cross property lines. If your garage sits two feet over the property line onto your neighbor’s land, that’s an encroachment that must be disclosed.

Water and sewer questions address whether the property is connected to public systems or uses private wells and septic. If the septic system failed inspection two years ago and was repaired, that’s relevant history buyers need to know.

If a seller knowingly provides false or incomplete information on the disclosure statement, they can be liable for actual damages resulting from the defect. A breach of contract real estate case can be filed before or after closing, and it can continue for up to six years after the sale.

How Easement Disputes Affect Property Rights in Long Island

An easement is a legal right that allows someone else to use a portion of your property for a specific purpose. Common examples include shared driveways, utility access, and rights of way. Easements don’t transfer ownership, but they do restrict how you can use your own land.

Easement disputes happen when property owners disagree about the scope of use, maintenance responsibilities, or whether an easement even exists. In New York, easements can be created by written agreement, by necessity, or by prescription through continuous use over at least ten years.

Right-of-way easements allow access across another property and are commonly used for shared driveways and private roads. Disputes involving right-of-way easements are among the most frequent in Long Island. Questions about who can use the driveway, who pays for repairs, and whether the easement allows parking often end up in litigation.

Utility easements allow companies to install and maintain electrical lines, water pipes, and telecommunications infrastructure. These easements typically run with the property deed, meaning they transfer automatically when the property is sold. You might not realize your property has utility easements until you try to build an addition and discover power lines run underground exactly where you planned to dig.

Drainage easements allow water to flow across one property for the benefit of another. They help manage stormwater and prevent flooding but can create disputes when maintenance responsibilities are unclear. If your property has a drainage easement and the drainage system gets clogged, who’s responsible for clearing it?

Prescriptive easements arise when someone uses another person’s property openly, continuously, and without permission for at least ten years. This doesn’t grant ownership, only the right to continue the use. A neighbor who has crossed the corner of your property to reach their backyard for fifteen years might have a prescriptive easement to continue doing so.

The rights and responsibilities of each party depend on how the easement was created and the language governing it. In general, the easement holder may use the property only for the stated purpose, while the property owner retains ownership and overall control of the land. Neither party may interfere with the other’s lawful rights.

Easement issues often lead to property contract disputes involving access, boundaries, development rights, and property value. Because easements can be complex and highly fact-specific, resolving these disputes usually requires legal representation from someone who understands New York real estate law and can negotiate solutions before conflicts escalate into expensive litigation.

Getting Legal Protection Before Closing Day

Real estate contracts in Long Island, NY involve serious financial risk. Hidden liens can attach to your property for debts you never created. Disclosure violations can cost you tens of thousands in repairs the seller should have warned you about. Easement disputes can restrict how you use your own land.

The contract you sign determines whether you have legal protection when these problems surface. Generic contract language leaves you vulnerable. Specific terms negotiated before you’re locked in give you leverage to demand solutions before problems become your responsibility.

Most people sign real estate contracts without fully understanding what they’re agreeing to. They trust that standard forms protect their interests. They assume title insurance covers everything. Those assumptions cost money when reality doesn’t match expectations.
