The Will That Forgot Half the Family: Estate Planning for Blended Families in New Jersey

Somewhere in a Surrogate’s Court file right now, there is a will that forgot half a family. It was not written carelessly. It was written by someone who meant well, assumed their spouse would take care of everyone, and never thought through what happens when that assumption turns out to be wrong. In blended families, that assumption is one of the most expensive mistakes an estate plan can make. According to U.S. Census data, 16 percent of children in the United States live in blended families, yet most estate planning documents are written as if every family has one set of children, one prior marriage, and no complications.

Before you sit down with an attorney, there are questions your family needs to answer. The attorney can draft the documents. Only you can decide what you actually want them to say.

What the Law Does by Default in a Blended Family

New Jersey’s intestacy laws, the rules that govern what happens when someone dies without a will, were not written with blended families in mind. Under New Jersey statute, stepchildren who have not been legally adopted have no automatic right to inherit from a stepparent. According to the 2024 New Jersey Revised Statutes, Title 3B:1-1, the legal definition of “child” specifically excludes any individual who is only a stepchild. If a stepparent dies without a will, a stepchild receives nothing from that estate regardless of how long they lived together, how close the relationship was, or what the stepparent intended.

The intestacy rules for a surviving spouse in a blended family can also produce outcomes no one would have chosen. If a person dies with a surviving spouse and biological children from a prior relationship, the spouse receives 25 percent of the estate plus one half of the remaining balance. The biological children divide the rest. Whether that result is fair depends entirely on the family’s specific circumstances, but the statute does not ask. It applies uniformly. A plan that says something different has to be written down.

The Questions to Answer Before Any Documents Are Drafted

The most valuable thing a blended family can do before an estate planning meeting is have the hard conversations the attorney cannot have for them. These are the questions that shape every document that follows.

Who do we each consider our children? This sounds obvious, but blended families often include biological children, stepchildren, half-siblings, and children from prior relationships who may or may not have a legal relationship to both spouses. Each person needs to decide, explicitly, who they want to provide for and in what proportion. Assuming the answer is obvious is how people end up with estate plans that contradict their intentions.

What do we want to happen when the first spouse dies? The most common default in blended family planning is to leave everything to the surviving spouse. This feels natural and protective. The problem is that the surviving spouse is then free to leave everything to their own biological children, leaving your children with nothing. If you leave your entire estate to your spouse and your spouse later changes their will or remarries, your children’s inheritance may evaporate entirely. The plan needs to address this scenario directly.

What happens to the house? The family home is often the most emotionally and financially significant asset in a blended family estate. Who owns it currently, and how is it titled? If both spouses are on the deed, what happens to the surviving spouse’s right to live there versus the children’s right to eventually inherit it? These two interests can conflict, and a plan that does not address the conflict explicitly will leave someone without the outcome they expected.

How do we want to treat biological and stepchildren relative to each other? Some blended families want to treat all children equally regardless of biological connection. Others want to ensure that each parent’s assets flow to their own children. Both are legitimate choices. Neither one happens by accident. The documents have to say so.

What if we divorce? New Jersey law automatically revokes any provisions in a will that benefit a former spouse upon divorce. Unlike wills, the effect of divorce on trusts and other non-probate arrangements can be more complex and depends on the governing document and applicable law. A plan that relies on a trust but does not account for the possibility of a future divorce may leave provisions in place that the parties would have wanted to remove.

How New Jersey Treats Stepchildren for Inheritance Tax Purposes

One New Jersey-specific detail that surprises many blended families is how the state’s inheritance tax treats stepchildren. New Jersey imposes an inheritance tax on transfers to certain beneficiaries based on their relationship to the deceased. Transfers to Class A beneficiaries, which include spouses, children, grandchildren, parents, and stepchildren, are exempt from the tax entirely.

Stepchildren are Class A beneficiaries in New Jersey. That means a bequest from a stepparent to a stepchild is not subject to New Jersey inheritance tax, even if the stepparent never legally adopted the child. This is a meaningful distinction from intestacy, where stepchildren receive nothing by default. A will or trust that specifically names a stepchild as a beneficiary triggers no inheritance tax in New Jersey.

One additional nuance worth noting: New Jersey’s inheritance tax regulations, readopted in November 2025 with amendments effective December 2025, explicitly expanded the Class A definition to include children conceived through assisted reproductive technology. For blended families that include children born through IVF or similar methods, New Jersey now recognizes them as Class A beneficiaries. Any estate plan predating those amendments should be reviewed to ensure beneficiary designations and will language reflect the current rules.

Why Leaving Everything to Your Spouse Is Usually the Wrong Move

The impulse to leave everything to a surviving spouse is understandable. It is also the planning choice most likely to leave biological children unprotected in a blended family context.

When one spouse leaves everything to the other outright, the surviving spouse becomes the sole owner of all those assets. They can spend them, gift them, change their beneficiary designations, and ultimately leave them to whoever they choose. If the surviving spouse remarries, has a falling out with their stepchildren, or simply makes different choices as their own circumstances change, your biological children may receive nothing. The original intent is unenforceable because no legal structure protected it.

Pew Research Center data shows that six out of ten women who remarry are in blended families, and in roughly half of those remarriages, stepchildren live with the couple. That prevalence means the scenario described above is not an edge case. It is a common outcome in families that did not plan specifically for it.

The Trust Structures That Work for Blended Families

A qualified terminable interest property trust, commonly called a QTIP trust, is one of the most widely used tools for blended family planning. It allows the first spouse to die to provide for the surviving spouse during their lifetime, while ensuring that whatever remains at the surviving spouse’s death passes to the first spouse’s biological children. The surviving spouse receives income from the trust and may have access to principal under certain conditions, but cannot change who ultimately receives the assets. This structure balances the competing interests of both the surviving spouse and the children from a prior relationship.

A discretionary trust gives a trustee authority to distribute income and principal to the surviving spouse based on need, while protecting the underlying assets for the ultimate beneficiaries. This approach requires a trustee whose judgment both spouses trust, since the discretion is real and the decisions will matter.

For couples who want to keep their assets entirely separate and ensure each person’s estate flows to their own children, a plan that leaves assets directly to biological children while providing for the surviving spouse through life insurance, jointly owned property, or a separate trust can accomplish that goal without the complications of combining estates.

There is no single right answer for blended families. The right structure depends on the ages of the children, the financial circumstances of each spouse, the nature of the relationships involved, and what each person considers fair. What is consistent across every blended family is this: the default rules often will not produce the outcome a blended family intends, and the only way to change the outcome is to plan for it explicitly.
