Buying a Co-op in NYC: The Lien Search, UCC Filings and Why There Is No Deed

A co-op closing in New York City runs on a co-op lien search, not a title search, because the buyer is not getting real property. A co-op buyer acquires shares in the cooperative corporation that owns the building, plus a proprietary lease for the apartment. Under New York law that bundle is a “cooperative interest,” treated as personal property and governed by Article 9 of the Uniform Commercial Code (UCC). There is no deed to record and no fee title for the buyer to insure.

This guide covers what a co-op lien search checks, how co-op loans are filed and cleared through ACRIS, why an old UCC-1 can hold up a closing, whether you need title insurance for a co-op, and which closing costs still apply. It covers NYC co-ops under New York State law; the filing office differs for Staten Island, as noted below.

What you are actually buying

The co-op corporation holds the deed to the land and building, and any building mortgage is the corporation’s debt. Each apartment is represented by:

A stock certificate for the shares allocated to the apartment.
A proprietary lease giving the shareholder the right to occupy it.

New York’s UCC defines a cooperative interest as an ownership interest in a cooperative organization that carries proprietary possessory rights to identified space, and New York law governs perfection of a security interest in one regardless of other choice-of-law rules (UCC § 9-301(e)).

The practical consequences follow from that. Ownership passes by assignment of the lease and delivery of the stock, with board approval, not by a recorded deed. The buyer’s lender takes a pledge of the shares and lease and files a UCC financing statement instead of recording a mortgage. That is also why co-op loans pay no mortgage recording tax and cannot use a CEMA (see mortgage recording tax in NYC and Westchester).

What a co-op lien search checks

The buyer’s attorney, or the buyer’s lender, orders a co-op lien search from a title or search company after the contract is signed. It is a set of public record searches, certified by the search company, against the people and entities in the deal: the seller, the buyer and the co-op corporation.

Search	Against	What it finds
UCC filings	Seller, unit	Open share loans
Judgments	Seller, buyer	Money judgments
Federal tax liens	Seller, buyer	IRS lien notices
Bankruptcy	Seller, buyer	Pending cases
Building fee owner	Co-op corp	Who holds title
Building mortgages	Block and lot	Underlying loans
Patriot Act / OFAC	Parties	Sanctions matches

Exact coverage varies by search company and by what the lender requires. One NYC search company, for example, describes its co-op search as certifying the building’s fee owner, searching open mortgages and liens on the block and lot, and running county and state searches against the purchaser, seller and co-op corporation.

Where the filings are. In Manhattan, Brooklyn, Queens and the Bronx, the filing office for a co-op UCC financing statement is the City Register; elsewhere in the state it is the County Clerk (UCC § 9-501). Staten Island co-op filings are therefore made with the Richmond County Clerk, not in ACRIS. A notice of federal tax lien against an individual is filed where the person lives: for a resident of the four ACRIS boroughs, with the City Register (Lien Law § 240). A seller who lives outside the city needs a search in that county too.

Why a judgment matters even without a deed. A docketed money judgment is a lien on the debtor’s real property in that county (CPLR 5203). Co-op shares are personal property, so the judgment creditor gets priority against them only after delivering an execution to the sheriff (CPLR 5202). That is why a judgment against the seller is treated as a closing issue: the creditor can levy on the shares, and a buyer and lender want it paid or shown not to belong to the seller. Name-match clearance works the same way as on a house; see what happens when a lien or judgment turns up.

What the search does not cover. It does not insure anything. The search company certifies the records it searched, and its liability for errors is limited by the terms of its report. It also does not show the apartment’s maintenance arrears, assessments or the building’s financial condition. Those come from the managing agent and the buyer’s attorney’s review of the offering plan, financial statements and board minutes.

UCC filings for co-op loans

When a buyer finances, the lender files an initial UCC financing statement (UCC-1) with a cooperative addendum. The addendum must identify the unit’s street address, county, municipality, tax block and lot, and the name of the co-op corporation (UCC § 9-502(e)). The filing office indexes it under the debtor’s and each owner of record’s names and by block (UCC § 9-519(d)).

In the four ACRIS boroughs, co-op financing statements are filed through ACRIS. As of October 2026, the City Register charges $40 for a paper filing with addendum, or $20 electronically, with the same fees for amendments and terminations; block and lot numbers are required on every filing. In ACRIS these appear under document types such as UCC1 and INIC; see how to read ACRIS for title.

Why an old UCC-1 delays a co-op closing

Most UCC financing statements lapse after five years. A co-op financing statement filed with a cooperative addendum lasts 50 years (UCC § 9-515(h)). So a loan the seller paid off in 2009 can still show as open on the 2026 lien search unless someone filed a termination.

A UCC-3 termination statement removes it. New York has a co-op specific rule: when the shareholder sells or pays off the loan at a closing (a “cooperative interest settlement”), the secured party must deliver a termination or partial release to the closing on authenticated demand with sufficient notice. If the loan is paid outside a closing, the secured party must file the termination within one month after payment (UCC § 9-513(e)). Lenders do not always do this, and old filings often belong to banks that have since merged.

What to do. Sellers should search their own unit before listing and ask any prior lender for a UCC-3 for a loan already paid. At closing, the seller’s attorney orders the payoff letter for the current loan and arranges for the lender to deliver the UCC-3, the original stock certificate and the original proprietary lease, which the lender holds as collateral. A stale UCC-1 from a defunct lender usually takes the most time; the buyer’s lender and attorney decide what substitute proof they will accept.

The recognition agreement

A share lender needs the co-op corporation to acknowledge its interest. That is done in a three-party recognition agreement among the buyer, lender and co-op, commonly on a standard industry form known as the Aztech form. Fannie Mae requires co-op project documents to provide either a separate recognition agreement or equivalent provisions, including notice to the lender of a 90-day maintenance delinquency and the lender’s right to cure (Fannie Mae Selling Guide B4-2.3-03). The same section allows the share loan to sit behind the co-op’s own lien on the shares for unpaid maintenance and assessments where local custom provides for it. Check the proprietary lease for the co-op’s lien and the recognition agreement for how the two rank.

The co-op usually signs through its managing agent, so build that turnaround into the closing date.

Board approval, flip tax and the managing agent

The board must approve the buyer before the transfer. A lender selling the loan to Fannie Mae must show that approval was given (same Fannie Mae section). Expect the board application, interview and approval letter to set the closing timeline more than anything in the lien search.

A flip tax is a transfer fee paid to the co-op on a sale. New York’s Business Corporation Law provides that a co-op’s shares are not unequal because of fees payable to the corporation on a sale or transfer, if those fees are set out in the proprietary leases, occupancy agreements or offering plan (BCL § 501(c)). That is the statutory footing for flip taxes. The lease or house rules say how it is calculated and who pays; it is usually the seller’s cost unless the contract shifts it.

The managing agent also supplies the closing package: maintenance and assessment status, any transfer and processing fees, the lease assignment forms and the new stock certificate.

Lost stock certificate

The seller must deliver the original stock certificate and proprietary lease, or the lender’s if a loan is open. If the certificate is lost, the corporation may issue a replacement, and the board may require the owner to post a bond (BCL § 508(e)). Under the UCC, an issuer must replace a lost certificate if the owner asks before the issuer learns a protected purchaser acquired it, files a sufficient indemnity bond and meets the issuer’s other reasonable requirements (UCC § 8-405). In practice the managing agent asks for a lost certificate affidavit plus a bond or indemnity, so start this as soon as the certificate cannot be found. Estates are a common source of this problem; see selling an inherited house or apartment.

Do you need title insurance for a co-op?

Not in the way a house buyer does. There is no fee title for the buyer, so there is no standard owner’s policy on the apartment, and most NYC co-op purchases close on a lien search alone.

Insurance products do exist:

Proprietary leasehold coverage. The TIRSA Cooperative Endorsement attaches to an owner’s policy and insures a “Proprietary Leasehold Estate.” It covers matters such as the building not being vested in a validly formed cooperative, certain unpaid taxes and maintenance charges due at the policy date, and a right of first refusal that could have been exercised. Mortgages on the building are listed as exceptions. Under the TIRSA rate manual the endorsement itself carries no charge; the premium is for the underlying policy (see the title bill explained).
UCC insurance. Some underwriters issue UCC policies for New York cooperative interests, such as First American’s EAGLE9 UCC NY Cooperative Interest Policy. Lenders sometimes require this kind of coverage in place of, or on top of, a lien search with limited liability.

Whether to buy either is a choice for the buyer, or a requirement of the lender; no New York law requires it.

Co-op closing costs that still apply

A co-op skips the deed recording, mortgage recording tax and owner’s title premium, but transfer taxes still apply:

NYC Real Property Transfer Tax (RPTT) applies to transfers of cooperative housing stock shares: 1% up to $500,000 and 1.425% above for an individual co-op apartment. The return is filed electronically through ACRIS within 30 days.
NYS transfer tax applies to conveyances of co-op shares tied to a proprietary lease (Tax Law § 1405-B).
Mansion tax of 1% applies to a residential conveyance of $1 million or more, and the statute names “a cooperative apartment unit” (Tax Law § 1402-a). The buyer pays.

Rates, the NYC supplemental tiers and who pays what are in NYC and NYS transfer tax. For a full buyer and seller budget, including lien search, UCC filing, recognition agreement and managing agent fees, see NYC closing costs.
