1. Why Can a Title Search Miss an Unapproved Apartment?
A title search can show no competing owner while the building file shows an unapproved conversion. These records answer different legal questions.
Recorded Ownership and Mortgage Interests
The Nassau County Clerk records deeds, mortgages, and satisfactions. Under Real Property Law § 291, an earlier unrecorded conveyance may lose priority to a qualifying later purchaser who acts in good faith, gives value, and records first. Recording does not make a forged deed valid. An attorney can compare the chain of title and lien releases. A land title recording review may reveal whether the next step is obtaining a missing satisfaction, correcting an instrument, or contesting an adverse claim.
Permits and Certificates of Occupancy
For parcels inside the incorporated Village of Mineola, Code § 495-41 requires occupancy approval before a new building is used or an existing building's use changes. Subsection B separately limits continued occupancy after completion of work that required a building permit. Its 30-day provision does not authorize an otherwise unapproved apartment for 30 days. Compare the listing with approved plans. A Mineola postal address alone does not establish Village jurisdiction.
| Document | What to Verify | Where to Look |
|---|---|---|
| Deed or mortgage | Recorded ownership and liens | Nassau County Clerk |
| Survey | Boundaries and improvements | Surveyor or owner |
| Permit or occupancy certificate | Approved work and use | Applicable building department |
2. What Can an Attorney Address before Closing?
Before a buyer is bound by a purchase contract, the parties can define who must resolve an occupancy discrepancy and when. Once a contract is signed, the available choices depend largely on its wording.
Contract Conditions and Seller Promises
General Obligations Law § 5-703 generally requires a written sale contract or sufficient memorandum signed by the party to be charged, subject to exceptions. A seller's verbal assurance may not change the signed terms. An attorney can examine title objections, inspection contingencies, repair provisions, and notice deadlines. A real estate transaction review may identify whether the buyer can request documents, negotiate a written correction, or seek an extension.
Disclosure Versus Independent Verification
For covered residential transactions, Real Property Law §§ 462–463 govern the seller's condition disclosure and exemptions. The form asks about certificates of occupancy, but buyers should not treat an answer as municipal approval. A written amendment can assign responsibility for approvals, set a closing deadline, and identify proof of completion. The lender may impose additional conditions.
3. What If the Problem Surfaces after the Deed Transfers?
A post-closing discovery does not automatically revive an expired contingency. The response depends on what was promised, which facts the seller disclosed, and whether the defect concerns ownership or use.
A Recorded Lien or Competing Deed
An unreleased mortgage may reflect a recording gap rather than an unpaid loan. Check payoff records and the title policy before treating the lien as unpaid. Under RPAPL § 1501, a person with a qualifying interest may seek a determination of an adverse property claim. That procedure does not itself authorize building use.
A Unit That Cannot Be Legally Rented
The owner may need approved plans, an inspection, corrective construction, or permission for a changed use. Seller liability depends on the agreement, required disclosures, and proof of any alleged misrepresentation or loss. A missing certificate alone does not establish a right to recover every legalization expense. Preserve the listing, signed disclosures, inspection report, permit history, and communications showing when each party learned of the issue.
4. Which Authority Should Handle the Problem?

A recording office cannot approve an apartment, and a building department cannot decide who owns the land. The remedy may require a municipal application, a corrected recording, or a lawsuit.
Municipal Review or Court Action
The County Clerk does not hold title reports, private surveys, or occupancy certificates. The Village Building Department handles applicable permits; contested ownership may require a claim in Nassau County Supreme Court in Mineola. New Supreme Court cases generally require NYSCEF electronic filing under the Nassau protocol effective July 7, 2025; unrepresented litigants are exempt. An attorney handling real estate dispute resolution can evaluate negotiation, a corrective instrument, or a court claim without confusing those remedies with municipal approval.
Practical Pitfalls before Responding
Keep the original transaction file and check the applicable contract and court deadlines. Three mistakes can change a buyer's position:
- Assuming a title search proves a rental unit is permitted.
- Relying on verbal promises instead of written closing conditions.
- Waiting for a permit decision while a contractual notice period expires.
Rules also differ between states. California real estate attorney guidance addresses California disputes, not the requirements governing a New York parcel.
5. Frequently Asked Questions
How Much Does a Real Estate Attorney Typically Cost in New York?
A defined closing may involve a flat fee, while a disputed title or occupancy matter may require hourly billing and separate expenses. A $400 hourly rate cannot be evaluated without the work involved. Under 22 NYCRR Part 1215, covered engagements generally require written fee terms, with exceptions including expected fees under $3,000.
Does Title Insurance Cover an Illegal Apartment?
A standard owner's policy generally focuses on insured title risks and often excludes building-code or zoning violations. Certain forms or endorsements may cover specified enforcement risks. Review the policy, exclusions, and endorsements rather than assuming that insurance pays to legalize an unapproved unit.
