Avoiding common New York estate planning mistakes means building a plan that actually works under New York law: a properly executed will, current beneficiary designations and powers of attorney, and an honest reckoning with how Surrogate’s Court probate and the spousal right of election will treat your assets. Most failed estate plans in New York don’t fail because the person had too little money — they fail because the documents were stale, improperly signed, or quietly overridden by a beneficiary form nobody reviewed in fifteen years. The good news is that nearly every one of these mistakes is preventable once you know where the traps are.
I’ve spent years in front of New York’s Surrogate’s Courts watching well-intentioned plans unravel. The patterns repeat. Below are the errors I see most often in Manhattan — especially among retirees and seasonal residents who split their time between the city and somewhere warmer — and how to fix each one before your family inherits the problem.
Mistake #1: Assuming a will avoids probate in New York
This is the single most common misconception I encounter. A will does not avoid probate. A will is the instrument that governs probate. When you die owning assets in your sole name, your executor must petition the Surrogate’s Court in the county where you were domiciled — New York County for most Manhattan residents — to admit the will and receive letters testamentary. That process is governed by the Surrogate’s Court Procedure Act (SCPA), and it takes time, costs money, and becomes part of the public record.
If your estate is modest, New York offers a streamlined path. Under SCPA Article 13, an estate with personal property of $50,000 or less (real property is not counted) can often be settled through voluntary administration — what most people call “small estate” administration — without full probate. But the moment you own a co-op share, a brownstone, or a brokerage account that pushes you past that threshold in your sole name, full probate is back on the table.
The cleaner solution for many Manhattan retirees is a revocable living trust. Assets you transfer into the trust during your lifetime pass to your beneficiaries outside of probate entirely, privately, and often faster. The catch — and it’s a big one — is that the trust only controls what you actually retitle into it. An unfunded trust is an expensive piece of paper. If you create one, fund it: deed the real estate, retitle the accounts, and don’t stop halfway.
Mistake #2: Letting beneficiary designations override your entire plan
Your will controls only your probate estate. It has zero power over assets that pass by contract: life insurance, IRAs, 401(k)s, and any account with a payable-on-death or transfer-on-death designation. Those flow directly to whoever is named on the form — regardless of what your beautifully drafted will says.
I have seen an ex-spouse inherit a seven-figure retirement account because a beneficiary form was never updated after a divorce twenty years earlier. New York’s revocation-on-divorce rules under the EPTL revoke certain dispositions to a former spouse, but you should never rely on a statute to clean up paperwork you can fix in ten minutes.
- Pull every beneficiary form — retirement accounts, life insurance, annuities, and bank/brokerage TOD designations.
- Confirm primary and contingent beneficiaries are named. A missing contingent beneficiary can force an asset back into probate.
- Re-check after every life event: marriage, divorce, birth, death, or a major move.
- Coordinate the forms with your will and trust so they tell one consistent story.
Mistake #3: Ignoring the spousal right of election
You cannot fully disinherit a spouse in New York. Under EPTL 5-1.1-A, a surviving spouse has a right of election to claim the greater of $50,000 or one-third of the net estate — and critically, that “elective share” estate reaches beyond the probate estate to capture many testamentary substitutes, such as certain joint accounts, Totten trusts, and revocable transfers.
This matters enormously in second marriages and blended families, which are common among the retirees I work with. If your plan tries to leave everything to children from a first marriage while your current spouse survives you, that spouse can elect against the estate and upend your intentions. The fix is to plan around the right of election deliberately — through valid prenuptial or postnuptial waivers, properly structured trusts, or candid conversations — rather than discovering the rule the hard way in Surrogate’s Court.
Mistake #4: Treating your power of attorney as an afterthought
Estate planning isn’t only about death. The documents that protect you while you’re alive but incapacitated are arguably more important day to day. The New York statutory durable power of attorney, governed by General Obligations Law (GOL) Article 5, Title 15 (GOL 5-1501), lets an agent manage your finances if you can’t.
New York substantially revised this form in 2021. Two practical points trip people up:
- Old forms still in circulation may not meet current requirements. A power of attorney executed under outdated rules can be questioned by banks. If yours predates 2021, have it reviewed.
- Gifting authority is not automatic. If you want your agent to make gifts above the modest statutory threshold — often essential for Medicaid planning — that authority must be expressly granted in the modifications section. Without it, your agent’s hands are tied at exactly the moment flexibility matters.
Pair the financial power of attorney with a health care proxy, which appoints someone to make medical decisions when you cannot speak for yourself. New York treats these as separate documents for good reason: the person you trust with your money may not be the person you want deciding about your care. Name both, and name backups.
Mistake #5: Owning property in two states without a coordinated plan
Many of my clients are snowbirds. They keep a Manhattan apartment and spend winters elsewhere. The danger is twofold. First, if you die owning real property in another state in your sole name, your family may face a second, separate probate — ancillary probate — in that state, on top of the New York proceeding. Second, domicile disputes can arise: which state was your true legal home? That question affects estate taxes and which court has primary jurisdiction.
A revocable living trust is the standard tool to sidestep multistate probate, because trust-held property doesn’t probate at all. If you maintain ties to more than one state, make sure your New York counsel and any out-of-state counsel are coordinating. We regularly work alongside our affiliated estate planning attorneys handling out-of-state property so that one consistent plan covers a client’s full footprint rather than two plans that contradict each other.
Mistake #6: Confusing tax planning with everyone-needs-it planning
New York has its own estate tax with a notorious feature people call the “cliff.” If your taxable estate exceeds the New York exemption by more than a small margin, you can lose the benefit of the exemption entirely and be taxed on the whole estate, not just the excess. The thresholds change over time, so I won’t quote a figure that may be stale by the time you read this — but the principle is durable: estates near the New York exemption line need real planning, and crossing it slightly can be far more expensive than crossing it by a lot.
That said, most New Yorkers don’t have a federal estate tax problem and shouldn’t let tax anxiety distract from the basics. The far more common need is protecting assets from long-term care costs. A Medicaid asset protection trust in New York can shelter your home and savings from nursing-home spend-down if it’s established well before care is needed, because of the look-back period. For clients receiving a fixed income who need to qualify for community Medicaid, a pooled income trust can preserve excess monthly income while keeping benefits intact. These are time-sensitive tools — the worst time to start is the week you need care.
Mistake #7: Signing documents incorrectly — or not at all
New York’s execution formalities are strict, and Surrogate’s Court enforces them. Under the EPTL, a will must be in writing, signed at the end by the testator, and witnessed by two competent witnesses, ideally with a self-proving affidavit so the witnesses don’t have to be tracked down years later. A trust must be signed and acknowledged. A power of attorney must be signed, dated, and acknowledged before a notary; the statutory gifts rider, where used, has its own witnessing requirements.
DIY kits and forms downloaded from the internet fail on these details constantly. A will witnessed by a beneficiary, a missing acknowledgment, a signature in the wrong place — any of these can invalidate the document or invite a will contest. The cost of doing it right once is a fraction of the cost of litigating it later.
Mistake #8: Writing the plan and never looking at it again
An estate plan is a snapshot of your life, your family, and the law on the day you signed it. All three change. The clients whose plans work are the ones who treat the documents as living things. Review your plan every three to five years, and immediately after any of these:
- A marriage, divorce, birth, or death in the family
- A move into or out of New York
- A significant change in assets — selling a business, buying property, an inheritance
- The incapacity of a named executor, trustee, or agent
- A meaningful change in tax or Medicaid law

The bottom line for Manhattan retirees and snowbirds
The estate planning mistakes that hurt families most aren’t exotic. They’re the boring ones: a beneficiary form nobody updated, a trust that was never funded, a power of attorney without gifting authority, a plan that ignored a spouse’s statutory rights. New York law gives you good tools — the EPTL, the SCPA, the statutory power of attorney, the health care proxy, and well-drafted trusts — but only if you use them correctly and keep them current. Get the foundation right, revisit it on schedule, and you spare the people you love a courthouse headache during the worst week of their lives.
Frequently Asked Questions
Does having a will avoid probate in New York?
No. A will does not avoid probate; it governs it. When you die owning assets in your sole name, your executor must petition the Surrogate’s Court (under the SCPA) to admit the will. To avoid probate, you generally need a funded revocable living trust, joint ownership, or beneficiary/TOD designations. Very small estates with $50,000 or less in personal property may qualify for voluntary administration under SCPA Article 13.
Can I disinherit my spouse in New York?
Not fully. Under EPTL 5-1.1-A, a surviving spouse has a right of election to claim the greater of $50,000 or one-third of the net estate, and that elective share reaches many testamentary substitutes such as certain joint accounts and revocable transfers. You can only limit a spouse’s share through a valid prenuptial or postnuptial waiver or careful planning.
Why does my power of attorney need updating if it still looks valid?
New York substantially revised its statutory durable power of attorney form (GOL 5-1501) in 2021. Older forms may be rejected by banks, and gifting authority above a small statutory threshold must be expressly granted, which is essential for Medicaid planning. If your power of attorney predates 2021, have an attorney review it.
I split my time between Manhattan and another state. What estate planning issue should I watch for?
Owning real property in two states can trigger a second, separate ancillary probate in the other state and create domicile disputes that affect estate taxes. A funded revocable living trust holding your out-of-state property is the standard way to avoid multistate probate, and your New York and out-of-state counsel should coordinate one consistent plan.
When should a New Yorker set up a Medicaid asset protection trust?
Well before care is needed. Because of the Medicaid look-back period, transferring assets into a Medicaid asset protection trust must happen years in advance to fully shelter your home and savings from nursing-home spend-down. For those needing community Medicaid with excess monthly income, a pooled income trust can preserve benefits. Both are time-sensitive, so plan early.
