Key Takeaways
- A co-op owner holds shares in a corporation, not a deed to real property.
- A proprietary lease grants the right to occupy a specific apartment unit.

- A properly funded trust can hold co-op shares if the board approves it.
- Joint ownership of co-op shares only delays probate, it does not avoid it.
Katzner Law Group works with cooperative apartment owners across New York who assume their co-op fits neatly into a standard estate plan, only to learn otherwise. What is a co-op property, in legal terms, and why does that distinction matter once inheritance is on the table? A co-op is not real estate the way a house or condo is. It is a share in a corporation, paired with a lease granting the right to live in the unit. That structure changes how the asset transfers at death, whether it passes through probate, and whether a trust can hold it. Here is what co-op owners in New York need to know.

What Is a Co-Op Property?
A cooperative apartment, or co-op, is a form of housing ownership common throughout New York City. Rather than owning a unit outright, a co-op owner holds shares in the corporation that owns the entire building. Those shares come bundled with a proprietary lease, granting the shareholder the right to occupy one specific apartment. Answering what is a co-op property in legal terms comes down to this: it is personal property, not real property, under New York law, a distinction that shapes nearly every decision a co-op owner makes about inheritance, trusts, and probate.
How Does Co-Op Ownership Work?
Understanding what a co-op owner actually holds title to makes every later estate planning decision easier to follow.
What Do You Actually Own When You Buy a Co-Op?
When someone buys into a co-op, they are not purchasing a unit. They are purchasing shares of stock in the cooperative corporation that owns the building. The number of shares assigned to an apartment typically reflects its size, floor, and layout. Ownership of those shares does not by itself grant occupancy. Occupancy comes from a second document, the proprietary lease, issued alongside the shares and tied to a specific unit. Both pieces move together. Shares without the lease carry little practical value, and the lease cannot exist without the shares behind it.
What Is a Proprietary Lease?
A proprietary lease is a lease between the cooperative corporation and a shareholder that grants the right to occupy a specific apartment. It runs alongside stock ownership rather than in place of it, lasting as long as the shareholder holds the shares tied to that unit. The proprietary lease also contains many of the rules that matter most for estate planning, including whether shares can move into a trust and how board approval works before a new occupant moves in.
How Is a Co-Op Different From a Condo?
A condo owner holds a deed to real property that transfers at death the same way a house does. A co-op owner holds shares in a corporation, treated as personal property under New York law. This affects almost everything downstream. A condo transfers through a will or trust without anyone else’s permission. A co-op transfer, by contrast, is filtered through the board, which retains the right to approve or reject a new shareholder, including an heir or trust beneficiary. Anyone planning around a co-op needs to account for that extra layer of control.
What Happens to a Co-Op When the Owner Dies?
Once a co-op owner passes away, the shares and proprietary lease do not transfer automatically. Several factors determine what happens next, starting with whether the shares were held individually, jointly, or in trust.
Can a Co-Op Be Inherited?
Yes, a co-op can be inherited. Under New York’s Estates, Powers and Trusts Law, every estate in property may be devised or bequeathed, which includes co-op shares. Naming an heir in a will or trust is legally valid, but it only decides who is entitled to the shares, not whether that person actually becomes a shareholder. As covered above, the board still stands between an heir and the apartment itself, which is why co-op inheritance takes more planning than inheriting most other assets.
What Happens to Co-Op Shares After Death?
When a shareholder dies with the co-op titled in their own name, their co-op shares and proprietary lease become part of the probate estate, and someone needs legal authority to act before those shares can move. That authority typically comes from Letters Testamentary, if there was a will, or Letters of Administration, if not. These Letters are issued via the time consuming, expensive, and public process known as probate. The executor or administrator then works with the co-op’s managing agent and board to transfer or sell the shares, and the board generally will not deal with anyone else in the meantime.
Does a Co-Op Have to Go Through Probate?
In most cases, yes, unless you plan via a trust (discussed below). Because co-op shares are personal property rather than real property, there is no deed to simply pass along, and that classification is what pulls them into Surrogate’s Court, the same as a bank account or a car. An executor needs the court’s authority before doing anything with the shares. From there, the board-approval step still applies, layered on top of the probate timeline rather than replacing it. This combination of two separate processes is why co-op owners often plan around probate specifically, most often through a properly funded trust.
Can You Put a Co-Op in a Trust?
Placing co-op shares into a trust is possible in New York, and it will meaningfully change how those shares pass at death. It is not automatic, though, and it depends on cooperation and consent from the co-op board.
Benefits of Including a Co-Op in a Trust
New York law permits every estate in property to be disposed of through a lifetime trust, and co-op shares fall within that broad language. When a co-op is transferred into a revocable living trust during the owner’s lifetime, the shares can pass to beneficiaries without going through Surrogate’s Court, since the trust already holds legal title. This keeps the transfer private and lets the owner set terms for how and when a beneficiary receives the shares. This is a massive win for co-op owners, one not to be understated.
Potential Challenges When Transferring a Co-Op to a Trust
The biggest obstacle is not legal; it is practical. Most co-op boards require their written consent before shares move into a trust, and some decline outright or attach conditions, such as requiring the original owner to remain both trustee and occupant (which is not a big hurdle). If the shares carry a mortgage, the lender holding the recognition agreement may need to approve the transfer too. Skipping this step can leave a trust holding shares the board never agreed to recognize.
How Should You Include a Co-Op in Your Estate Plan?
A workable estate plan for a co-op has to address the building’s own rules alongside the usual estate planning documents.
Review Your Co-Op’s Governing Documents
Before making any decisions, an owner should locate and read the proprietary lease, the bylaws, and any house rules in effect. They should discuss what trust transfers are permitted with the managing agent of the co-op. These documents set out whether shares can move into a trust, what the board requires for approval, and any restrictions that could affect a beneficiary later.
Choose Your Beneficiaries
Deciding who inherits the shares is only part of the picture. An owner should also consider whether that beneficiary could realistically satisfy the board’s financial and occupancy requirements, since a rejection can leave an otherwise valid inheritance in limbo.
Plan Instead With a Trust
For owners who want to avoid probate for the co-op, a revocable living trust is usually the strongest option, provided the board consents. Funding the trust correctly, meaning actually retitling the shares in the trust’s name with board approval, matters just as much as creating the trust document itself. Once those are done though, the expensive, time consuming, and public probate process will be avoided entirely.
Coordinate Your Estate Plan With the Co-Op Board
Many owners draft a full estate plan without ever contacting the board, then discover at the worst time that the board will not recognize the transfer. Reaching out early, in writing, to confirm what the board requires can prevent months of delay later.
What Happens to a Co-Op If There Is No Estate Plan?
Without a will or trust, a co-op owner’s shares pass through intestacy, meaning New York law via the probate court, not the owner, decides who inherits. A court appoints an administrator, who must then seek the co-op board’s approval before any heir becomes a recognized shareholder. This adds a layer of review on top of an already lengthy probate process, and strips the owner of any say in who manages the shares meanwhile. A death with no plan in place, and a board that still has to approve whatever happens next, is a headache no one wants to inflict on their loved ones.
Common Estate Planning Mistakes Co-Op Owners Make
The most common mistake is assuming that adding a family member as a joint shareholder solves the probate problem. As Gabriel Katzner often explains when discussing jointly held assets generally, joint ownership does not eliminate probate, it only delays it until the second owner dies, and it assumes the asset is actually held jointly, which is not always true once reviewed (this approach also creates massive income tax and asset protection issues). A second mistake is assuming a will alone keeps a co-op out of probate. A third is failing to notify the board of a trust or estate plan until after death, adding avoidable delay for the family. Each of these mistakes shares the same root cause: treating a co-op like any other asset instead of planning around board consent and a co-op’s personal property status from the start.
Frequently Asked Questions About Co-Op Properties and Estate Planning
Can I Leave My Co-Op to My Children?
Yes, but the co-op board must approve the transfer before your children can become recognized shareholders, even if your will or trust names them directly.
Can a Beneficiary Sell a Co-Op?
Yes, once the board approves them as the shareholder of record, a beneficiary can generally sell the shares subject to the same board approval process any seller would face.
Can I Put My Co-Op in a Revocable Living Trust?
Generally yes, provided the co-op board consents to the transfer in writing. Some boards require the original owner to remain both trustee and occupant, obtain lender consent, etc.
Does a Co-Op Go Through Probate?
In most cases, yes. Because co-op shares are personal property, they typically must pass through Surrogate’s Court unless they were already transferred into a properly funded trust.
What Happens to My Co-Op Mortgage When I Die?
The lender’s recognition agreement generally must be addressed before the shares transfer. Any outstanding share loan typically needs to be resolved or assumed as part of the transfer process.
