Mechanics Liens in New York: What Contractors Can File, What Property Owners Can Fight, and How It All Gets Resolved

A mechanics lien in New York can freeze a property’s title with surprisingly little paperwork, but according to Alexander Paykin, Esq., founder of Paykin Law, a New York real estate and commercial litigation firm, that ease of filing is exactly why so many liens fall apart once they’re challenged.

Paykin says the pattern he sees is consistent: contractors file with minimal documentation, assume the filing itself gives them leverage, and then can’t back up the claim when a property owner pushes back. “The contractors are usually sloppy in writing up their liens, and they’re even worse at documenting everything and being able to prove their liens,” he says.

How Little It Takes to File

The initial lien filing requires only basic information: a general description of the work performed, the amount claimed, and the last day work was done. Paykin notes that many contractors use lien filing services that do little more than plug in a total dollar figure; the lien attaches to the property with no receipts, no itemization, and no proof behind it yet.

That’s often where the trouble starts.

The Eight-Month Deadline

For private improvements, a mechanics lien has to be filed during the work or within eight months of the last day work was performed. Miss that window, and the lien right disappears; though the contractor can still sue for breach of contract, they lose the ability to freeze the property.

Paykin says the “last day of work” listed on a filing is worth scrutinizing, since it’s sometimes inaccurate. Property owners with a Ring or Nest camera, delivery records, or similar documentation can sometimes prove the contractor stopped showing up well before the date claimed. As Paykin put it, if a homeowner can show the contractor “stopped showing up three weeks earlier, and the contractor waited seven and a half months to file their lien, well, gotcha.”

There’s a second deadline contractors frequently miss as well: after filing, they still have to commence litigation to foreclose on the lien. Sitting on it too long costs them that right too.

Where the Section 38 Demand Exposes the Gaps

Once a lien is filed, a property owner can serve a Lien Law Section 38 demand, requiring the contractor to produce a full itemized accounting. This is where Paykin says most cases collapse: “Suddenly, it turns out the contractor can’t find any of the receipts for the materials he allegedly provided. Suddenly, the contractor can’t present any proof as to the work that was done.”

Once those gaps surface, the property owner can move under Lien Law Section 39 to reduce or dismiss the lien entirely, and in some cases pursue punitive damages, since an unsupportable lien clouds title and can block a sale or refinance.

Paykin also points out that a lien, on its own, isn’t a money judgment. Filing it only puts the world on notice of a claim; the contractor still has to sue, and win, before collecting anything.

What Contractors Should Do Instead

Paykin’s advice to contractors is straightforward: treat documentation as part of the job, not something to reconstruct after a dispute starts. “Keep all your documentation. Log everything. Log every time you’re at the property. Log every material you buy. Keep receipts. Keep proofs. Keep everything,” he says. And once a client stops paying, file the lien promptly rather than waiting; there’s no upside to sitting on it.

What Property Owners Should Do First

For property owners who discover a lien, Paykin flags two common mistakes: paying right away and contacting the contractor directly.

“Don’t pay. If you don’t feel you’re supposed to be paying, don’t pay right away. Speak to a lawyer first,” he says. Reaching out to the contractor carries its own risk; an angry phone call or email can become evidence, and Paykin notes there’s a good chance those exchanges are being recorded or preserved for exactly that purpose.

For an owner who needs the lien off the property quickly, to close on a refinance, for example, Paykin points to Lien Law Section 19: posting an undertaking of 110% of the lien amount with the county clerk removes the lien from the property while the underlying dispute is resolved separately. That undertaking can be bonded rather than posted in cash, which reduces the immediate financial hit.

The bottom line, in Paykin’s view, is that both sides tend to lose ground the same way, by treating something informal (a handshake, a rushed filing, an unrecorded conversation) as if it will hold up later. It rarely does.
