NYC Title, Deed and Lien Search: An ACRIS Guide

Before you buy, refinance, or research a New York City property, much of its legal history is already public. The city records deeds, mortgages, and liens in ACRIS, an online database anyone can search. Reading those documents tells you who owns a property, what it owes, and what claims are attached to it. This guide explains what each record means, how a title search differs from a formal title report, and where a pre-purchase reader should look.

ACRIS: New York City's system of record

ACRIS, the Automated City Register Information System, is New York City's official record of property documents. The Department of Finance maintains it, and it is the primary source for recorded deeds, mortgages, and liens. The system covers documents from 1966 to the present.

Because these records are public, you do not need to own a property, or hire anyone, to read its filed history. You can search by address, by a parcel's borough-block-lot number (the BBL, the city's unique tax identifier for a piece of land), or by the name of a party to a document.

What ACRIS shows is the paper trail: the documents themselves, the dates they were recorded, and the parties named on them. It does not interpret them for you, which is why knowing what each record type means matters.

Deed, mortgage, lien: what each document tells you

A deed is the document that transfers ownership from one party to another. Reading the chain of deeds, meaning each recorded transfer over time, shows you who currently holds title (the legal ownership of the property) and how ownership has changed hands. The most recent deed names the current owner of record.

A mortgage is a loan secured by the property. A recorded mortgage tells you the property was pledged as collateral for a debt; a later satisfaction, or release, indicates that debt was paid off. An open mortgage that was never satisfied on paper can raise a question a closing needs to resolve.

A lien is a legal claim against the property for money owed. It can arise from unpaid property taxes, water and sewer charges, certain municipal debts, or unpaid judgments. A lien travels with the property, not just the person who incurred it, so it becomes the concern of whoever owns the parcel next.

A title search versus a formal title report

A title search is the act of reading the public record to reconstruct a property's history: who has owned it, what is borrowed against it, and what claims are outstanding. You can do a basic version yourself through ACRIS, and it is a reasonable first pass before making an offer or ordering deeper work.

A formal title report, sometimes called a title abstract, is a different thing. It is a professional examination prepared by a title company that compiles the chain of title, flags defects and exceptions, and underpins title insurance at closing. It carries legal weight and financial backing that a self-serve search does not.

Put simply, a public-record search tells you what is filed; a title report certifies what it means and stands behind it. The first is useful for orientation and due diligence; the second is what lenders and buyers rely on to actually close.

How liens attach to the property, and clear at closing

Two kinds of lien come up often in New York City. A tax lien is a claim for unpaid property taxes, water or sewer charges, or certain municipal debts. Left unpaid, these can be enforced against the property itself.

The second kind is a docketed judgment lien. When a fine goes unpaid, for example an unpaid Environmental Control Board (ECB) summons adjudicated at the city's Office of Administrative Trials and Hearings (OATH), it can be entered, or docketed, as a judgment lien against the property rather than only against the owner. Once docketed, it attaches to the parcel and appears on title searches.

Both kinds generally must be cleared at closing: the debt is paid, or otherwise resolved, so that title passes clean to the buyer. This is why open liens found in the public record matter well before a sale, since they can hold up a deal or reduce what a seller nets. You can screen a parcel for recorded claims with an NYC lien search by address, then verify anything you find against the agency of record.

How to look up a property's chain of title and open liens

You can start directly at ACRIS. Search by address or by BBL, and it returns the documents recorded against that parcel. Sort by document type and date to rebuild the timeline: deeds show ownership transfers, mortgages show borrowing, and satisfactions show debts marked paid.

Read the most recent deed first to confirm the current owner of record, then work backward through earlier deeds to see the chain of title. For debts, note any mortgage without a matching satisfaction and any recorded lien, judgment, or lis pendens (a recorded notice that litigation affecting the property is pending).

If you would rather see a parcel's ownership and document history compiled in one view, a consolidated NYC title and deed history pulled from ACRIS can save time. Treat any such summary as a starting point, and confirm the underlying documents in ACRIS itself before relying on them.

Where the public record stops

The public record is strong on documents that were filed, but it is not a guarantee of clean title. Some claims are not recorded in ACRIS, filings can contain errors, and a document's legal effect is not always obvious from its face.

That is why a self-serve search is due diligence, not a substitute for the professionals who close a deal. A title company and a real estate attorney examine the record, resolve defects, and back their work; a title search you run yourself does none of those things.

This guide is general information, not legal advice. For anything that affects a purchase, refinance, or dispute, verify specifics with the relevant city agency and have a title company or attorney review the record before you rely on it.
