Seven Mechanic’s Lien Mistakes to Avoid in Albany

Reviewed September 7, 2026.

New York mechanic’s liens have separate requirements for the notice, filing, service and enforcement. These seven checks help identify common problems on Albany projects, but they are not a complete validity review.

1. An inadequate property description

Lien Law § 9 requires a description sufficient to identify the property, including its street and number in a city or village if known. Verify the legal parcel, county, property identifiers and interest to be charged. A project nickname or billing address is not a substitute for title research. Whether an error can be corrected depends on the defect and applicable law; do not assume either that every typo defeats the lien or that every mistake is harmless.

2. Using the wrong filing deadline

Under § 10, the usual private-improvement period is eight months from the last qualifying work or materials, with a four-month rule for single-family dwellings and a separate 90-day rule for retainage after its release was due. Two-family property is not automatically subject to four months. The statute contains a defined developer-owned subdivision exception to single-family treatment. Review condominium, cooperative and common-element work on its facts.

For a public improvement, § 12 allows filing before completion and acceptance and within 30 days after both occur. The invoice date or payment demand does not replace the relevant statutory trigger. Preserve records supporting the work and dates claimed.

3. Serving the wrong recipients or using the wrong method

For private liens, § 11 governs owner service and § 11-b governs certified-mail service on specified contracting parties, including the general contractor for certain lower-tier claimants. The private service window is five days before through 30 days after filing. Public liens follow § 11-c, with service five days before or simultaneously with filing.

4. Missing the proof-of-service filing

For private liens, file the required service proof within 35 days after filing the notice. Mailing the notice and retaining a postal receipt are not substitutes for filing proof with the clerk. Public-lien proof must be on or filed with the notice as § 11-c requires.

5. Failing to investigate the owner and property interest

Use current title information and distinguish the contracting party from the owner. Section 9 expressly protects against certain failures to name or descriptions of the true owner or contractor, so an inaccurate owner name is not automatically fatal in every case. That provision does not eliminate the need to identify the property interest, establish lien rights against it and satisfy service. Seek prompt advice about any proposed correction.

6. An unsupported description of the work or materials

Describe the actual lienable labor and materials clearly and support the value, unpaid amount and dates with project records. Avoid vague descriptions that conceal what the claim covers. Specially manufactured materials and other unusual claims require their own legal assessment.

7. Willfully exaggerating the amount

Credit payments and supported offsets, reconcile extras and retainage, and exclude amounts that do not belong in the lien. § 39 can void a willfully exaggerated lien. In a qualifying enforcement proceeding, § 39-a provides specified damages, including the exaggeration and certain discharge expenses and fees. An honest dispute or mistake is not automatically willful exaggeration, and the statute does not impose automatic triple damages.

After filing, separately calendar expiration, extension and foreclosure requirements. Filing does not itself collect the debt.
