The most common New York estate planning mistakes are simple to describe and surprisingly easy to make: not having a valid will at all, signing documents that don’t meet New York’s execution rules, ignoring how the spousal right of election works under EPTL 5-1.1-A, and forgetting that assets with beneficiary designations pass outside your will entirely. For young families and first-time planners in Manhattan, these errors usually surface at the worst possible moment, after someone has died, when they are far harder and more expensive to fix.
I’ve spent years in New York’s Surrogate’s Courts watching well-meaning people leave behind plans that didn’t do what they thought. The good news is that almost every mistake I see is preventable with a little foresight. Below is a practical walk-through of the traps New Yorkers fall into most, and how to step around them.
Mistake #1: Assuming You’re Too Young or Too “Normal” to Need a Plan
The single biggest mistake is doing nothing. People in their thirties with a mortgage, a couple of kids, and a 401(k) often assume estate planning is for the wealthy or the elderly. It isn’t. If you have a minor child, you have a reason to plan, full stop.
When a New Yorker dies without a will, they die intestate, and the state’s intestacy statute (EPTL 4-1.1) decides who inherits, not you. For a married parent, that often means your spouse receives the first $50,000 plus half the balance, and your children split the rest. That sounds reasonable until you realize a minor child cannot legally receive an inheritance directly. The money gets tied up under court supervision, and a guardian of the property may have to be appointed, with annual accountings to the Surrogate’s Court. A simple will, or better yet a trust, avoids that machinery entirely.
Intestacy also means you have no say over who raises your children. The nomination of a guardian for minors belongs in your will. Skip the will and you’ve handed that decision to a judge who never met your family.
Mistake #2: Botching the Way the Will Is Signed
New York is strict about execution formalities, and homemade or download-template wills fail here constantly. Under EPTL 3-2.1, a valid will must be:
- In writing and signed by you (the testator) at the end of the document;
- Signed or acknowledged in the presence of two witnesses;
- Witnessed within a 30-day window of one another; and
- Declared by you to the witnesses to be your will.
Miss one of these steps and the document may be thrown out in probate, sending your estate right back into intestacy. A related fix that costs nothing extra: have the witnesses sign a self-proving affidavit at the same time. Without it, your executor may have to track down those witnesses years later to testify in Surrogate’s Court, which is exactly the kind of avoidable headache that delays an estate for months.
Don’t Let a Beneficiary Witness Your Will
Here’s a subtle one. Under EPTL 3-3.2, if a beneficiary serves as one of your two witnesses, the gift to that witness can be void. The will itself may survive, but the person you wanted to provide for could lose their bequest. Always use disinterested witnesses.
Mistake #3: Forgetting the Spousal Right of Election
You cannot fully disinherit a spouse in New York, and people are routinely caught off guard by this. 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, regardless of what your will says. This right reaches not just probate assets but also many “testamentary substitutes,” such as certain joint accounts, payable-on-death accounts, and gifts made in contemplation of death.
This matters most in blended families. Suppose you remarry and want everything to go to children from a first marriage. Without proper planning, perhaps a waiver in a prenuptial or postnuptial agreement, or a carefully structured trust, your new spouse can override that intention by electing against the will. Plan around the right of election deliberately; don’t pretend it isn’t there.
Mistake #4: Ignoring Assets That Pass Outside Your Will
This is the mistake that quietly undoes more plans than any other. Your will controls only probate assets. A large share of a typical New York family’s wealth, including life insurance, IRAs, 401(k)s, and accounts with payable-on-death or transfer-on-death designations, passes by beneficiary designation, completely outside the will.
I regularly meet people whose will leaves “everything equally to my three children,” while their $400,000 life insurance policy still names an ex-spouse from a designation they filled out a decade ago. The beneficiary form wins. The will is irrelevant to that asset.
- Pull every beneficiary designation you have, retirement accounts, insurance, brokerage TOD forms, and read who is actually named.
- Update them after every major life event: marriage, divorce, a new child, a death in the family.
- Think hard before naming a minor child directly. A minor can’t manage the funds, which can force a court guardianship of the property. Naming a trust as beneficiary is often cleaner.
- Coordinate the designations with your overall plan so nothing contradicts your will.
Coordination is the whole game. A will, a trust, and your beneficiary forms have to tell one consistent story.
Mistake #5: Overlooking Incapacity Documents
Estate planning isn’t only about death. The documents that protect you while you’re alive but incapacitated are arguably more important to a young family, and they’re the ones people forget.
The New York Statutory Durable Power of Attorney
A power of attorney lets someone you trust handle your finances if you can’t. New York overhauled its statutory durable power of attorney form under General Obligations Law 5-1501, effective June 2021, with simpler signing rules and built-in penalties for institutions that wrongly reject a valid POA. Two cautions: an out-of-date pre-2021 form can cause friction at banks, and large gifting authority requires specific language in the gift rider. Don’t assume an old form pulled from a drawer will still work smoothly.
The Health Care Proxy
Separately, New York’s Health Care Proxy law lets you appoint an agent to make medical decisions if you cannot speak for yourself. A POA does not cover health care choices, so you need both. Pair the proxy with a living will expressing your wishes about life-sustaining treatment. Without these, your family may face a court guardianship proceeding under Article 81 of the Mental Hygiene Law just to make routine decisions for you, a slow and public process you can sidestep with a few signatures today.
Mistake #6: Assuming a Will Avoids Probate (It Doesn’t)
A frequent misconception is that having a will keeps your family out of court. The opposite is true: a will is the document that gets administered through probate, the Surrogate’s Court process governed by the Surrogate’s Court Procedure Act (SCPA). Your nominated executor petitions the court, notifies the people who would inherit under intestacy, and only then receives letters testamentary to act.
For modest estates, New York offers a lighter path. Voluntary administration, the “small estate” procedure under SCPA Article 13, is available when the decedent’s personal property (excluding real estate) falls at or below the statutory threshold, currently $50,000. It’s faster and cheaper than full probate. But if you own real property in your name alone, or your estate exceeds that limit, you’re in the full process.
If avoiding probate is a real goal, perhaps because you own a Manhattan co-op or condo, or because you value privacy, the tool to consider is a revocable living trust. Assets you properly transfer into the trust during your life pass to your beneficiaries without Surrogate’s Court involvement. Which brings us to the next mistake.
Mistake #7: Creating a Trust and Never Funding It
A revocable living trust only avoids probate for the assets actually titled in the trust’s name. I’ve seen beautifully drafted trusts sit empty because no one ever retitled the bank accounts, the brokerage account, or the apartment. An unfunded trust avoids nothing; the assets left outside it still go through probate.
Funding is the unglamorous follow-through that makes the whole plan work: changing deeds, retitling accounts, and updating beneficiary forms to align with the trust. Build it into your plan from day one rather than treating it as a someday task.
Mistake #8: Confusing Estate Planning With Long-Term Care Planning
Young families often don’t think about this, but it’s worth knowing early because the planning timelines are long. New York has its own estate tax with a different (and lower) exemption than the federal one, and a notable “cliff” that can tax the entire estate if you exceed the threshold by more than 5 percent. Equally important for many families is Medicaid planning for future long-term care, where transfers and asset-protection structures must be set up years in advance to be effective. A specialized vehicle such as a Medicaid Asset Protection Trust in New York has to be funded well before care is needed, because of look-back rules. For individuals with disabilities or those trying to preserve benefits eligibility, a pooled income trust can be the right tool. These are not last-minute fixes.
Mistake #9: Writing a Plan and Never Revisiting It
An estate plan is a snapshot of your life on the day you signed it. Lives change. The plan should too. Review yours after any of these:
- Marriage, divorce, or remarriage;
- The birth or adoption of a child;
- The death of a named executor, guardian, trustee, or beneficiary;
- A significant change in assets, such as buying a home;
- A move to or from New York, since execution rules and taxes vary by state.
As a baseline, dust off your documents every three to five years even if nothing major has happened. Naming a guardian when your child is two and never revisiting it when that guardian moves across the country is a classic, fixable oversight.
A Note for Manhattan Families
City living adds wrinkles. Co-op ownership, in particular, complicates trust funding, because transferring shares into a trust usually requires board approval and review of the proprietary lease. Real estate that crosses state lines, a city apartment and a weekend house upstate or out of state, can trigger probate in more than one jurisdiction unless planned for. These aren’t reasons to avoid planning; they’re reasons to do it with someone who knows New York law and how the boroughs actually work.
If you’re just getting started, begin with the basics: a properly executed will, a statutory durable power of attorney, and a health care proxy. From there, decide whether a revocable trust or asset-protection planning fits your goals. You can read more about the foundational documents on our wills overview and about what happens after death on our New York probate page. Families with Florida ties may also want guidance from an affiliated Florida estate planning team to keep multi-state assets coordinated.
The thread running through every mistake above is the same: estate planning fails when the pieces don’t talk to each other, or when there are no pieces at all. Get the documents right, sign them correctly, coordinate your beneficiary designations, fund what needs funding, and revisit it as life moves. Do that, and you spare the people you love the slow, costly cleanup that brings so many families to Surrogate’s Court in the first place.

Frequently Asked Questions
Can I disinherit my spouse in New York?
Generally no. 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, which reaches both probate assets and many testamentary substitutes like joint and payable-on-death accounts. You can only override this through a valid waiver, such as one in a prenuptial or postnuptial agreement, or by carefully structured planning.
Does having a will let my family avoid probate in New York?
No. A will is the document administered through probate in Surrogate’s Court under the SCPA. To avoid probate, you generally need a fully funded revocable living trust or assets that pass by beneficiary designation or joint ownership. Small estates of $50,000 or less in personal property may qualify for the simpler voluntary administration under SCPA Article 13.
What documents do young families in Manhattan need first?
Start with three: a properly executed will under EPTL 3-2.1 that names a guardian for minor children, a New York statutory durable power of attorney under GOL 5-1501 for finances, and a health care proxy for medical decisions. From there you can consider a revocable living trust or long-term care planning depending on your goals.
Why do beneficiary designations matter if I already have a will?
Because your will only controls probate assets. Life insurance, IRAs, 401(k)s, and accounts with payable-on-death or transfer-on-death forms pass directly to whoever is named on the designation, regardless of what your will says. Outdated designations, like an ex-spouse still listed on a policy, are one of the most common ways an estate plan fails.
How often should I update my New York estate plan?
Review it after any major life event, marriage, divorce, the birth or adoption of a child, a death among your named fiduciaries or beneficiaries, a major change in assets, or a move to a different state. Even without a triggering event, revisit your documents every three to five years.
