The 15 Most Common Trust Mistakes

Trust problems rarely happen because “the law is too complicated.” Most come from small oversights. Here are the 15 mistakes we see most often in New York.

Mistake 1: Signing the Trust but Never Funding It

The problem: New York law says a trust is valid only as to assets actually transferred to it (EPTL §7-1.18). If the house is still in your name and the accounts were never retitled, your family still goes through probate.
How to avoid it: Right after signing, list your assets and complete each deed, retitling or beneficiary designation. (See Part 7.)

Mistake 2: Thinking “All My Property Belongs to the Trust” Is Enough

The problem: The same statute says that a general statement like this does not count as a transfer.
How to avoid it: Record a new deed for real estate, re-register accounts, and sign specific assignments for other property.

Mistake 3: Retitling an IRA or 401(k) to the Trust

The problem: It may be treated as a full withdrawal, with income tax on the entire balance.
How to avoid it: For retirement accounts, change only the beneficiary form, never the owner. (See Part 12.)

Mistake 4: Beneficiary Forms That Contradict the Trust

The problem: Beneficiary forms override your will and trust. If the trust says “equally to my three children” but the policy names only your eldest son, only he gets paid.
How to avoid it: Review the beneficiaries on every retirement account, insurance policy, annuity and POD/TOD account each year, and make sure they match your plan.

Mistake 5: Not Updating After Divorce or Remarriage

The problem: New York law automatically revokes revocable arrangements in favor of a former spouse to the extent permitted by law (EPTL §5-1.4), but employer retirement plans and group life insurance governed by federal law generally still pay whoever is named on the form. After remarriage, a new spouse’s legal rights can also affect your plan.
How to avoid it: After a divorce or remarriage, update everything: trust, will and every beneficiary form.

Mistake 6: Believing a Revocable Trust Protects Assets or Helps With Medicaid

The problem: Property in a revocable trust is still yours. It does not block your creditors (EPTL §7-3.1), and it counts when you apply for Medicaid.
How to avoid it: If the goal is long-term care planning, you need an irrevocable Medicaid asset protection trust, set up early. (See Parts 5 and 6.)

Mistake 7: Deeding the House to Your Children, or Adding Them to the Deed

The problem: Your children lose the step-up in basis at your death and may pay much more capital gains tax when they sell. The house is exposed to your children’s debts and divorces, and you need their signatures to sell or refinance.
How to avoid it: In most cases, a trust is safer than an outright transfer. (See Part 8.)

Mistake 8: Skipping Co-op Board Approval

The problem: Transferring a co-op to a trust requires board approval. Transferring without consent may breach the lease. Not transferring at all means your family faces probate.
How to avoid it: Contact the managing agent and prepare the application as soon as the trust is signed. (See Part 9.)

Mistake 9: Signing Formalities That Don’t Meet New York Requirements

The problem: New York requires a trust to be acknowledged or signed before two witnesses (EPTL §7-1.17). Out-of-state templates found online often miss this.
How to avoid it: Have an attorney familiar with New York law supervise the signing.

Mistake 10: The Wrong Trustee, or No Successor Trustee

The problem:
- You named only your spouse as successor trustee. What if your spouse is ill too?
- Two children who don’t get along must sign jointly, so nothing gets done;
- You chose someone who is not good with money, or who lives overseas and can’t easily act.
How to avoid it: Name one or two backup successor trustees; state whether co-trustees can act alone; consider a professional trustee if needed.

Mistake 11: A Trust Without a Power of Attorney or Health Care Proxy

The problem: A trust controls only assets already in the trust. Retirement accounts, a car in your name, tax filings and dealings with government agencies all require a power of attorney (New York statutory short form, General Obligations Law §5-1513). Medical decisions require a health care proxy. If Medicaid planning may be needed, the power of attorney must expressly grant gifting authority.
How to avoid it: Prepare the trust, pour-over will, power of attorney, health care proxy and HIPAA authorization as one package.

Mistake 12: Naming Minors Directly as Beneficiaries

The problem: Insurers and banks cannot pay minors directly. A court may need to appoint a guardian, and the child receives everything at adulthood.
How to avoid it: Name the trust as beneficiary and let the trustee manage the money under your rules.

Mistake 13: Ignoring New York’s Estate Tax Cliff and Couples’ Planning

The problem: New York’s 2026 exclusion is $7,350,000. Above 105%, tax applies from the first dollar, and spouses cannot transfer unused exclusion to each other. Many people forget to count life insurance and retirement accounts and fall off the cliff without realizing it.
How to avoid it: Calculate your total assets including insurance regularly. Couples near the threshold should consider credit shelter, disclaimer or life insurance trusts.

Mistake 14: Your Family Doesn’t Know the Trust Exists or Can’t Find It

The problem: No matter how good the plan, if your family can’t find the originals or doesn’t know which attorney to call, it’s worth nothing.
How to avoid it: Tell your successor trustee where the documents are and who your attorney is. Keep an asset list and a contact list.

Mistake 15: Handwriting Changes on the Original Trust

The problem: Crossing out a beneficiary or writing “to my youngest daughter” on the original generally has no legal effect and may invite disputes.
How to avoid it: Make every change through a formal amendment that meets the signing requirements. (See Part 19.)

The Bottom Line

When a trust goes wrong, your family usually pays the price, often after it’s too late for you to fix. Reviewing your plan regularly matters more than making it complicated.

Attorney’s perspective

These 15 mistakes are exactly what I check, item by item, when I review a client’s existing trust. If you already have one, especially an online template or one signed years ago, consider a check-up of its signing formalities, funding and beneficiary forms.
