10 Estate Planning Mistakes to Avoid in New York

Signing the Trust but Never Funding It

This is the most common and the most damaging mistake. A revocable living trust is a legal container. When you sign the trust agreement, you create the container — but it's empty. Assets don't transfer into the trust automatically. You have to physically change the title on each asset: record a new deed for real property, retitle bank accounts, update brokerage accounts. Until you do that, those assets remain in your individual name and will go through probate when you die, exactly as if the trust didn't exist.

I've reviewed estates where the family paid $4,000 for a trust-based plan and then faced a full Surrogate's Court proceeding because the trust was never funded. The trust was perfectly drafted. It just contained nothing.

Complete the funding process immediately after signing your trust documents. Don't leave the attorney's office without a specific checklist of assets to transfer and instructions for how to do each one. See our article on how to fund a trust in New York for a step-by-step guide.

Outdated or Inconsistent Beneficiary Designations

Retirement accounts, life insurance policies, and pay-on-death bank accounts pass directly to whoever is named as beneficiary — completely bypassing your will and trust. Your will says "everything to my children equally." Your 401(k) still names your ex-spouse from a marriage that ended 11 years ago. The 401(k) goes to the ex-spouse. Full stop. The will is irrelevant for that asset.

I've seen this pattern cause devastating family conflict and irreversible financial harm. The survivor contest the designation, lose, and watch hundreds of thousands of dollars go to someone the deceased had cut out of their life a decade earlier.

Review every beneficiary designation when you create or update your estate plan, and again after any major life event — marriage, divorce, birth of a child, death of a named beneficiary. Keep a log of every policy and account with its current designation.

Ignoring New York's Estate Tax Cliff

New York's estate tax has a cliff that is unique among states and catches many families by surprise. If your estate exceeds 105% of the New York exemption (approximately $7.52 million in 2026), you lose the entire exemption — not just the excess above it. An estate worth $7.52 million can owe over $764,000 in New York estate tax; an estate worth $7.50 million might owe only $240,000. The difference of $20,000 in value costs over $500,000 in additional tax.

For New York City families with a high-value apartment, retirement savings, and life insurance, this threshold is within easy reach. And many of them think they have no estate tax concern because they're "below the $13 million federal exemption."

Get a current estate value estimate that includes all assets — real property, retirement accounts, life insurance death benefits, and business interests. If you're near the New York threshold, review strategies to reduce your taxable estate. See our guide on New York estate tax in 2026 for current numbers and planning strategies.

Using Joint Ownership as a Planning Substitute

Adding a child to the deed on your home "to avoid probate" seems like a simple shortcut. It isn't. When you add a joint owner to real property, you've made an irrevocable gift of half the property — immediately triggering a New York gift tax filing requirement if the value exceeds the annual exclusion, and potentially starting a Medicaid five-year look-back period. If the child has financial problems, their creditors can now reach your home. If they get divorced, their spouse may have a claim. If they die before you, their share goes through their estate, not back to you cleanly.

Joint ownership also destroys the stepped-up cost basis that a beneficiary receives when they inherit property through an estate. A child who inherits a $2 million home through an estate pays no capital gains tax if they sell it for $2 million. A child who received the property as a gift 10 years ago when it was worth $800,000 owes capital gains tax on the $1.2 million appreciation.

Use a revocable living trust or a life estate with enhanced powers (a "Lady Bird deed" — available in some states, though New York has limitations here) to accomplish your probate-avoidance goals without the downsides of joint ownership. Talk to an attorney before making any changes to real property title.

No Incapacity Plan

Estate planning isn't only about what happens when you die. It's about what happens if you can't manage your own affairs during your lifetime — due to a stroke, a serious accident, dementia, or any other incapacitating condition. Without a durable power of attorney and healthcare proxy, the people you trust most have no legal authority to act for you. They'll need to go to court under Article 81 to get that authority — a process that takes months and costs thousands of dollars, during which your bills may go unpaid, your investments may be unmanaged, and your medical decisions may be made by strangers.

Every adult in New York needs a durable power of attorney and a healthcare proxy. These documents are relatively inexpensive to prepare. There is no good reason not to have them. If yours were executed before 2021, New York updated the statutory short form — have them reviewed.

Leaving Assets Directly to Minor Children

If you name your child directly as a beneficiary of a life insurance policy or retirement account — or leave property to them outright in your will — and they're under 18 when they receive it, New York law requires court supervision of those assets until the child turns 18. A guardian of the property must be appointed. Annual court accountings may be required. The child gets everything on their 18th birthday with no restrictions. A 18-year-old receiving a $500,000 inheritance is a financial disaster waiting to happen in most cases.

Create a trust for any minor beneficiaries. Specify the distribution terms — for education and support while they're young, then staged distributions at ages like 25, 30, and 35. Name a trustee you trust to manage the funds responsibly. This approach is better in every dimension: no court supervision, no automatic lump sum at 18, better asset protection for the funds.

Choosing the Wrong Trustee or Executor

Selecting an executor or trustee based on sentiment rather than capability is a mistake I've cleaned up many times. The person you're closest to isn't necessarily the right person to manage a complex estate, file accurate accountings, make investment decisions, and communicate clearly with beneficiaries who may disagree with their choices. Family conflict often starts not with the will itself but with how the executor or trustee exercises their authority — or fails to.

I've seen executors who couldn't locate assets, couldn't produce a tax return on time, and spent months in conflict with beneficiaries over expenses they charged to the estate. The resulting litigation cost the estate far more than a professional administrator would have.

Choose executors and trustees who are organized, financially competent, capable of handling conflict without escalating it, and willing to take the responsibility seriously. For complex estates, consider naming a professional co-trustee or institutional trustee alongside a family member.

Forgetting Digital Assets

Digital assets are real assets with real value — cryptocurrency wallets, online investment accounts, PayPal balances, revenue-generating websites, digital media libraries. They're also uniquely difficult to access after death because they're password-protected and governed by terms of service that vary by platform.

New York enacted the Fiduciary Access to Digital Assets Act (FADAA), which allows a fiduciary to access digital assets under certain conditions. But the law only helps if your executor or trustee knows where to look, has the authority in your estate documents to access the accounts, and has practical access to the login credentials or recovery information.

Maintain a secure digital asset inventory — a list of accounts, platforms, and access information — and update it regularly. Make sure your power of attorney, trust, and will explicitly authorize your fiduciaries to access, manage, and distribute digital assets. See our guide on digital assets and estate planning in New York for specific steps.

Planning in a Vacuum — Ignoring the Full Picture

Estate planning that looks only at the will and trust — without coordinating beneficiary designations, retirement accounts, life insurance, business interests, and real property — is incomplete planning. I've seen plans where the trust carefully distributed 40% of the estate's value, while the other 60% (in retirement accounts and life insurance) went somewhere completely different because the beneficiary designations weren't aligned with the plan.

Similarly, estate planning that doesn't coordinate with your tax advisor can create unexpected income tax consequences — particularly around retirement account distributions, inherited IRA rules after the SECURE Act 2.0, and the basis step-up rules for inherited assets.

Your estate plan should account for every significant asset you own. Make a complete inventory first — then build the plan around the full picture. Review annually with your attorney and tax advisor together.

Never Updating the Plan

An estate plan signed in 2008 reflects 2008 tax law, 2008 asset values, 2008 family circumstances, and 2008 legal drafting standards. A lot has changed. New York significantly updated the power of attorney statute in 2021. The federal tax exemption has fluctuated dramatically. If you've had a divorce, remarriage, additional children, significant changes in wealth, the death of a named executor, or a move to a new state — your documents may no longer do what you think they do.

The most dangerous documents are the ones that were carefully drafted once and then forgotten. They give a false sense of security while the world has moved on around them.

Review your estate plan every 3–5 years even if nothing has changed, and immediately after any major life event. The review doesn't always require redrafting — sometimes a conversation with your attorney and a few updated beneficiary designations is enough. But you can't know that without looking.
