2. Why You May Need a Lawyer

Real estate deals in New York City frequently involve issues that require qualified legal counsel to review documents and negotiate protections. Below are concrete scenarios where a lawyer’s guidance is essential.

• Co-op or condo purchase with complex board requirements - A buyer submits a board package for a Midtown condo, but the package omits sublet restrictions and board interview timing. An attorney helps obtain the governing documents, interpret sublet limits, and prepare addenda to protect the buyer if approval is delayed or denied.
• Unpermitted work or code violations discovered during a deal - A purchaser learns of an open building department violation on a Brooklyn townhouse. An attorney coordinates title and DOB review, drafts cure letters, and negotiates credits or closing holdbacks to address fines and required remedies.
• Unclear or disputed property boundaries and survey errors - A Queens investment property has ambiguous boundary lines revealed by the survey. A real estate attorney arranges a precise survey, negotiates boundary adjustments, and ensures the deed reflects the corrected parcel description.
• Tax and rent- stabilized status affecting value and use - A buyer discovers rent-stabilized units in a mixed-use building. An attorney confirms status with the Housing and Preservation Department and drafts appropriate disclosures and contingency terms for rent-related risks.
• Complex lien or encumbrance profile - A multi-family building shows municipal liens and a mechanic’s lien. A lawyer coordinates a title search, negotiates lien releases, and structures closing protections for the buyer against undisclosed encumbrances.
• Zoning and land use constraints that affect intended development - A developer plans to convert a building to a higher density use but finds zoning restrictions. An attorney helps analyze the Zoning Resolution, confirms floor area ratio limits, and identifies possible variances or required approvals.
