If you and your partner live together in a Tribeca walk-up or a co-op on the Upper West Side but have never signed a marriage license, estate planning for unmarried couples in Manhattan is not optional housekeeping; it is the only thing standing between your partner and a New York intestacy statute that treats them as a complete stranger. Here is the fact that surprises almost every couple we meet: under New York’s Estate, Powers and Trusts Law, a surviving unmarried partner inherits exactly nothing by default, no matter how many decades you shared a home, a mortgage, or a life. Where a spouse would automatically take the first $50,000 plus half the estate under EPTL 4-1.1, an unmarried partner takes zero, and the assets pass to blood relatives the deceased may not have spoken to in years.
Why New York Law Leaves Unmarried Partners Out
New York abolished common-law marriage in 1933. That means no matter how long you have cohabited in Manhattan, you do not become “married enough” to inherit. The state recognizes legal marriage and registered domestic partnership, but the New York City Domestic Partnership registry confers only a narrow set of rights (such as certain hospital visitation and lease succession) and does not create inheritance rights under the EPTL.
When a person dies without a will, the intestacy rules of EPTL 4-1.1 distribute the estate to a fixed hierarchy of relatives: spouse, then children, then parents, then siblings, then more distant kin. A partner appears nowhere on that list. The Surrogate’s Court for New York County, located at 31 Chambers Street, will administer the estate strictly according to that statute, and the judge has no discretion to reward loyalty or recognize an informal commitment.
Spouse vs. Unmarried Partner: The Default Gap
The table below shows how starkly New York’s default rules diverge depending on marital status. This is what happens when there is no will, no trust, and no beneficiary designation.
| Right or Protection | Married Spouse | Unmarried Partner |
|---|---|---|
| Intestate inheritance (EPTL 4-1.1) | First $50,000 + half the estate | Nothing |
| Right of election (EPTL 5-1.1-A) | Guaranteed one-third minimum | None |
| Priority to administer estate (SCPA 1001) | First in line | Last, behind all kin and creditors |
| Family exemption (EPTL 5-3.1) | Yes | No |
| Default healthcare decision-maker | Yes (Family Health Care Decisions Act) | No (outranked by relatives) |
| NY estate tax marital deduction | Unlimited | None |
The Core Documents Every Unmarried Couple Needs
Because New York gives you no automatic protections, every right you want your partner to have must be created on paper. For unmarried Manhattan couples, the essential framework comes down to a coordinated set of documents that work together.
- A will. This is the single most important instrument. Your last will and testament is where you name your partner as a beneficiary and, equally important, name them as executor under SCPA 1001 so they (not an estranged sibling) control the probate process in New York County Surrogate’s Court.
- A revocable living trust. A funded revocable living trust lets assets pass to your partner privately, avoiding the public probate process and sidestepping the delays of a Surrogate’s Court proceeding entirely. For couples who own a Manhattan condo or co-op, this is often the cleanest path.
- A health care proxy and power of attorney. Your health care proxy and durable power of attorney appoint your partner to make medical and financial decisions if you are incapacitated. Without them, a hospital will turn to your blood relatives under the Family Health Care Decisions Act, and your partner may be locked out of the ICU.
- Beneficiary designations. Life insurance, retirement accounts, and TOD/POD accounts pass outside the will. Naming your partner directly on each one is a fast, powerful way to transfer wealth without probate.
Don’t Forget Disposition of Remains
Under New York Public Health Law 4201, the right to control burial and funeral arrangements goes to the next of kin unless you sign a written appointment of an agent. An unmarried partner has no default authority here. A simple disposition-of-remains form ensures your partner, not a distant cousin, decides how you are laid to rest.
Concrete Manhattan Scenarios
Abstract rules feel different when you map them onto real life in this city. Consider three common situations we see across the borough.
The Co-op on the Upper East Side
James and David have shared a co-op for fifteen years, but only James is on the proprietary lease and stock certificate. James dies without a will. Under EPTL 4-1.1, James’s estranged brother in Ohio inherits the shares, and the co-op board (which must approve any transfer) has no obligation to let David remain. A will leaving the shares to David, paired with advance board-approval planning, would have protected his home. Many co-op proprietary leases also contain succession clauses that recognize a registered domestic partner, so registering with the City and documenting the relationship matters.
The Joint Brooklyn-Born Brownstone, Now in Harlem
Maria and Elena bought a Harlem townhouse together as tenants in common, each owning 50%. Without a will, Elena’s half passes to her parents rather than to Maria, leaving Maria co-owning her own home with in-laws who may want to sell. Re-titling the property as joint tenants with right of survivorship would let the surviving partner take the whole property automatically, bypassing probate entirely.
The Incapacity Emergency
An unmarried partner suffers a stroke and is rushed to a Manhattan hospital. Without a health care proxy, the medical team follows the Family Health Care Decisions Act surrogate list, which places adult children, parents, and siblings ahead of an unmarried partner. The person who knows the patient best has no legal voice. A signed proxy reverses that result instantly.
Common Mistakes Unmarried Couples Make
Over years of practice in New York County, the same avoidable errors recur. Watch for these:
- Assuming time creates rights. Twenty years of cohabitation creates no inheritance right in New York. Only documents do.
- Relying on a joint bank account alone. A joint account may pass to the survivor, but it does not cover real estate, retirement plans, or healthcare authority.
- Forgetting the NY estate tax cliff. Unmarried partners get no marital deduction. With the New York estate tax exemption at $7.16 million for 2025 (indexed for 2026), and a notorious “cliff” that taxes the entire estate once you exceed roughly 105% of the exemption, larger estates need active planning, including credit-shelter and life-insurance trusts.
- Leaving stale beneficiary forms. A 401(k) still naming an ex-partner overrides your will. Review every designation after a breakup.
- Naming a partner without naming an executor. Leaving assets to your partner but failing to nominate them as executor under SCPA 1001 hands estate control to whichever relative petitions first.
- Skipping the disposition-of-remains form. Without it, funeral decisions default to next of kin under Public Health Law 4201.
For unmarried couples in New York, silence is a decision, and the statute writes a plan you would never choose. A coordinated will, trust, and proxy is the only way to override it.
When to Call an Attorney
You can buy a fill-in-the-blank will online, but unmarried couples have the least margin for error because the law’s defaults run against them. A small drafting flaw, an improperly witnessed will under EPTL 3-2.1, an unfunded trust, or a power of attorney that omits the statutory gift-rider can collapse the entire plan precisely when your partner needs it. When real property, retirement assets, blended families, or potential will contests from disinherited relatives are involved, work with an experienced NYC estate planning attorney who drafts these documents for Manhattan couples every week.
A qualified attorney will coordinate your will, trust, and incapacity documents so they reinforce rather than contradict each other, confirm correct execution under New York law, and structure your estate to minimize the New York estate tax cliff. You can review the official rules and forms through the New York County Surrogate’s Court, but the drafting and strategy are where professional guidance earns its keep.
In 2026, with Manhattan real estate values high and family structures more varied than ever, the cost of a properly drafted plan is trivial next to the cost of intestacy. If you are building a life with someone you have not married, the documents are the relationship’s legal backbone. Put them in place now, while it is simple, rather than leaving your partner to fight the EPTL after you are gone.
Frequently Asked Questions
Does my long-term partner inherit anything in New York if I die without a will?
No. New York abolished common-law marriage in 1933, and under EPTL 4-1.1 an unmarried partner inherits nothing by default. The estate passes to blood relatives in a fixed order, no matter how long you cohabited in Manhattan.
Does registering as domestic partners in New York City give us inheritance rights?
Not directly. The NYC Domestic Partnership registry provides limited rights such as hospital visitation and certain lease succession, but it does not create inheritance rights under the EPTL. You still need a will or trust to leave assets to your partner.
Can my partner make medical decisions for me if we are not married?
Only if you sign a health care proxy. Without one, New York’s Family Health Care Decisions Act gives priority to adult children, parents, and siblings ahead of an unmarried partner, so your partner could be excluded from critical medical decisions.
How do we protect a co-op or condo we share in Manhattan?
Title the property as joint tenants with right of survivorship so it passes automatically, or leave it through a will or revocable living trust. For co-ops, review the proprietary lease succession clause and plan around board approval requirements in advance.
Who handles my estate in Surrogate's Court if my partner and I are not married?
Whoever you nominate as executor in your will controls the process at the New York County Surrogate’s Court at 31 Chambers Street. Without a will, SCPA 1001 places your partner behind all blood relatives, so an estranged sibling could be appointed instead.
Is there an estate tax problem for unmarried couples in New York?
Yes. Unmarried partners receive no marital deduction, so transfers are fully exposed to the New York estate tax, which has a ‘cliff’ once you exceed roughly 105% of the exemption (about $7.16 million in 2025, indexed for 2026). Trust planning can reduce this exposure.
Will a joint bank account cover everything we own?
No. A joint account may pass to the survivor, but it does not transfer real estate, retirement accounts, or grant healthcare and financial decision-making authority. You still need a will, trust, health care proxy, and power of attorney.
Who controls my funeral arrangements if my partner and I are unmarried?
Under New York Public Health Law 4201, the right defaults to your next of kin unless you sign a written appointment of an agent. An unmarried partner has no automatic authority, so a disposition-of-remains form is essential.
