A client once came to my office after his brother, a lifelong bachelor living in Brooklyn, passed away without a will. My client and his sister were the only siblings and assumed they would inherit their brother’s apartment and savings. They were surprised—and distressed—to learn that because their mother was still alive, she was legally first in line to inherit the entire estate. They weren’t entitled to a dollar.
This is a common, painful discovery. Families often operate on assumptions, but New York law has a rigid hierarchy. When someone dies “intestate”—without a will—the state provides a default estate plan. For siblings, the state’s plan is rarely what they expect.
The Default Plan: New York’s Intestacy Laws
Without a will, asset distribution is governed by the Estates, Powers and Trusts Law (EPTL). EPTL § 4-1.1 dictates the order of inheritance. It’s a waterfall—the estate flows to the highest category of living relatives, and if that category is empty, it flows down to the next.
This is the order that matters for siblings:
- Spouse and Children: A surviving spouse and children are always first. If there’s a spouse and no children, the spouse inherits everything. If there are children but no spouse, the children inherit everything. If there are both, the spouse takes the first $50,000 plus half the remainder, and the children share the rest.
- Parents: If there is no spouse and no children, the estate goes to the deceased’s surviving parent or parents. This is the rule that surprised my client. Even if the parents are financially stable and the siblings are in need, the law is absolute.
- Siblings: Only when there is no surviving spouse, no children or grandchildren, and no parents do siblings inherit an estate in New York.
The law is not concerned with the emotional closeness of relationships or the financial needs of relatives. It is a mechanical application of a statute. For many families, the state’s presumption of who you would want to inherit does not match reality.
When “Sibling” Isn’t a Simple Term
The law also has precise definitions for who qualifies as a sibling. These definitions often complicate an already difficult time for a family.
For instance, half-siblings are treated exactly the same as full-blooded siblings. A sister who shares only one parent with the deceased has the same inheritance rights as a sister who shares both. Adopted children are also legally considered full siblings to other children in the adoptive family, with full inheritance rights.
What happens if a sibling has already passed away? If a deceased sibling left children—the nieces and nephews of the person whose estate is being settled—those children step into their parent’s place. They inherit their parent’s share “by representation.” If there were three siblings and one predeceased the estate owner, that deceased sibling’s one-third share would be divided equally among their own children.
These details matter. Administering an estate requires a complete and accurate accounting of the family tree. An overlooked heir can create significant legal and financial problems down the road in Surrogate’s Court.
Stewardship: A Will Overrides the State’s Plan
The intestate succession rules are a backstop, not a strategy. They exist for those who left no instructions. Executing a valid will is the only prudent way to direct your assets and provide for your family.
A will is your opportunity to override the state’s default plan. It is an act of intentional stewardship. With a will, you can:
- Name Your Beneficiaries: You can leave your entire estate to your siblings, even if you have a living parent. You can divide it in any proportion you see fit. You can also name a friend, a charity, or a more distant relative.
- Disinherit an Heir: A will is the only effective way to disinherit someone who would otherwise stand to inherit. If you have a sibling you do not wish to provide for, your will must state that explicitly.
- Appoint an Executor: You choose the person or institution you trust to be the fiduciary responsible for carrying out your wishes, rather than leaving it to the court to appoint an administrator.
Without a will, you have no say. The law takes over, and your family is left with a statutory framework that may not align with your relationships or your wishes. It is a legacy left to chance.
If you are a sibling in a family where a will was never created, or if you are considering your own estate plan, the first step is clarity. I often advise clients to begin by mapping their family tree against the legal hierarchy in the EPTL. That map is the foundation for making deliberate decisions about the legacy you wish to build.
