Ask a board which structure has the stronger position when an owner stops paying, and most directors give the intuitive answer: the co-op, because the co-op corporation owns the building and the resident only holds shares.
The intuition is reasonable and the conclusion is unreliable. On collections, a New York condominium board has a statutory remedy written directly into the Real Property Law. A co-op has something quite different — and something a great many boards misunderstand until the day they need it.
The condominium: a statutory lien, behind the mortgage
New York gives a condo board of managers an explicit tool.
Real Property Law §339-z provides that the board of managers, on behalf of the unit owners, has a lien on each unit for the unpaid common charges of that unit, together with interest. That lien is prior to all other liens, with three exceptions:
- Taxes on the unit in favor of an assessing unit, school district, special district, county, or other taxing unit;
- All sums unpaid on a first mortgage of record; and
- All sums unpaid on certain subordinate mortgages of record held by named public entities — among them the New York job development authority, the New York State urban development corporation, the Division of Housing and Community Renewal, the Housing Trust Fund Corporation, the New York City Housing Development Corporation, and in a city with a population of one million or more, the Department of Housing Preservation and Development.
The statute also provides that on a sale or conveyance of the unit, unpaid common charges are paid out of the sale proceeds or by the grantee.
Real Property Law §339-aa handles duration and enforcement. Any member of the board of managers may file a notice of lien if no notice has been filed within sixty days after the unpaid charges became due. The lien is then foreclosed by suit brought in the name of the board of managers, acting on behalf of the unit owners, in like manner as a mortgage of real property — and without needing to name as a defendant any person solely because they own a common interest in the property.
Read exception (2) again, because it is the one that governs the outcome. The board's lien is prior to most things, but it sits behind the first mortgage of record. In a unit with meaningful mortgage debt, foreclosing the common charge lien means taking subject to that mortgage. This is why experienced condo boards act on arrears early: the statutory position is genuinely good, and it erodes as the balance grows relative to the owner's equity.
The co-op: no lien, and no automatic shortcut
Now the part that surprises boards.
A co-op apartment is personal property, not real property. The resident owns shares in a corporation and holds a proprietary lease. There is no Real Property Law lien for maintenance arrears, because there is no real property interest to attach — the analysis runs through the Uniform Commercial Code, Article 9, against the shares and the lease.
Boards commonly assume that Article 9 gives the corporation an automatic security interest, on the theory that the proprietary lease requires the payment of maintenance and therefore functions as a security agreement.
New York courts have not reliably accepted that. Decisions in this area have held that a proprietary lease is not automatically a security agreement for the purpose of applying Article 9 remedies, and that a claim of maintenance arrears standing alone does not give rise to those remedies. The practical position that follows is that a co-op must demonstrate its entitlement to Article 9 rights rather than assume them — which in some buildings has meant entering into a separate security agreement with shareholders, in addition to the proprietary lease.
This is unsettled ground rather than a clean statutory rule, and a board should not act on the general description here. Have your attorney read your specific proprietary lease and confirm what the corporation actually holds before a single collection step is taken.
What the co-op does have, and what boards underuse, is that the proprietary lease is a lease. Non-payment of maintenance is non-payment under a lease, and the landlord-tenant path that follows is familiar, well-trodden, and frequently faster than a mortgage-style foreclosure. The corporation's strength is not a lien. It is the lease.
The comparison boards should actually draw
| Condominium | Co-operative | |
|---|---|---|
| Interest held by resident | Real property | Shares plus a proprietary lease |
| Statutory lien for arrears | Yes — RPL §339-z | None |
| Priority | Behind taxes and the first mortgage of record | Not applicable |
| Enforcement route | Notice of lien, foreclosure like a mortgage (§339-aa) | UCC Article 9 against the shares, if established — or the lease |
| Speed | Slower; foreclosure timelines | Potentially faster via the lease |
| Main trap | Assuming the lien outranks the mortgage | Assuming the lien exists at all |
Neither column is uniformly stronger. What decides an individual case is the building's own documents and the owner's own balance sheet.
What a board should do in the first sixty days
The remedies differ; the early discipline does not.
Establish the number precisely. What is owed, for what period, and what it comprises — base charges, assessments, late fees, legal fees. A board that cannot state the figure cleanly is not ready to act on it.
Read the documents on fees. Whether late charges and legal fees are recoverable is set by your declaration, by-laws, or proprietary lease. Where they are recoverable, pursuing a modest balance stops being uneconomic — which changes what the board should be willing to chase.
Find out whether there is a mortgage and who holds it. For a condo board this determines what a lien is actually worth. On a sponsor-affiliated co-op unit, establish separately whether a sponsor guarantee stands behind the obligation. Doing this after filing is doing it in the wrong order.
Ask why. A hardship that resolves is better handled with a documented payment agreement than with litigation, and boards that make this call well save the building money. The discipline is in what follows: document the agreement, and do not let a second agreement quietly follow a broken first one. The buildings that end up with unrecoverable arrears are almost never the ones that acted early and firmly.
Then act on the calendar, not on the mood of the meeting. The single most common failure here is not choosing the wrong remedy. It is choosing no remedy for eighteen months because each meeting has something more pressing on it — while the balance grows past the point where any remedy recovers it.
Arrears are also a budget issue, not only a legal one: a building carrying real arrears is running on less than it bills, and the board should know its collection position before it sets next year's increase. That connection is covered in board budget season.
Where this sits in management
Tracking arrears by unit, escalating on a defined schedule, and getting the board a straight answer about its actual position is a core part of condo association management and co-op board management, alongside the legal and regulatory compliance work that sits next to it.
If your board is carrying arrears it has not acted on, schedule a consultation or call 718-568-9278.
This article is general information, not legal advice. The co-op collection position in particular rests on case law that is unsettled and fact-specific, and every building's remedies depend on its own governing documents. Consult a qualified New York attorney before taking any collection step.
