Mistake #1: Not Having an Estate Plan at All
One of the most frequent and damaging errors is failing to create an estate plan. There is an old saying: If you don’t make a plan the government will make one for you. Without a will or trust, your assets will be distributed according to state law, which may not reflect your intentions. In both NY and NJ, this can result in:
- Probate delays and court involvement
- Unintended beneficiaries receiving assets
Begin your estate planning early, regardless of age or wealth.
Mistake #2: Failing to Update Your Documents
Life changes such as marriage, divorce, birth of children, or relocation can render your estate plan outdated. In New Jersey, for example, acquiring property in another state or changing financial status may affect how your estate is handled.
Review your estate plan every two to five years, after any major life event, or as situations change. Update beneficiary designations, asset lists, and legal documents to reflect your current wishes.
Mistake #3: Overlooking Non-Probate Assets
Assets like retirement accounts, life insurance policies, and jointly owned property can pass outside your will. In both NY and NJ, beneficiary designations on those accounts or property can override your estate plan. If these are outdated, your assets may go to unintended recipients.
It is important to coordinate your beneficiary designations with your overall estate plan. Ensure that account titles and joint ownerships align with your distribution goals.
Mistake #4: Ignoring State-Specific Tax Rules
New York and New Jersey have distinct estate and inheritance tax laws. While NJ eliminated its estate tax in 2018, it still imposes an inheritance tax on certain beneficiaries. For example:
- Class A beneficiaries (spouses, children, parents) are exempt – no inheritance tax;
- Class C and D beneficiaries (siblings, nieces, friends) may owe 11–16%;
- Step-grandchildren are not exempt, unlike stepchildren.
New York, on the other hand, has an estate tax with a “cliff” threshold, exceeding the exemption by even a small amount can trigger tax on the entire estate.
Work with an estate planning attorney familiar with NY and NJ laws. Strategic gifting, trust planning, and beneficiary structuring can help minimize tax exposure.
Mistake #5: DIY Estate Planning
Using generic online templates or fill-in-the-blank forms may seem cost-effective, but they often fail to meet state-specific legal requirements. Improper execution, lack of customization, and overlooked provisions can invalidate your documents.
Consult a qualified estate planning attorney. Professional guidance ensures your documents are legally sound, tailored to your needs, and compliant with NY/NJ statutes.
Mistake #6: Not Planning for Incapacity

Estate planning isn’t just about death, it is also about protecting yourself during life. Without proper powers of attorney and healthcare directives, your loved ones may need court approval to manage your affairs.
Include durable powers of attorney and advance directives in your estate plan. These documents authorize trusted individuals to make financial and medical decisions if you become incapacitated.
