Most Americans still do not have a will. According to Caring.com’s 2025 Wills Survey, only 24% of U.S. adults have one. Based on this statistic, about three out of four Americans could leave their estate to be distributed under state intestacy laws if they die without a valid estate plan.
What happens when someone dies without a will? When someone dies without a valid will, state law decides what happens to all the properties and assets they owned, unless those assets are not covered by probate. This process is called intestate succession, and it follows a statutory hierarchy that is fixed. This process usually doesn’t care about the deceased person’s real relationships, wishes, or surrounding circumstances. The outcome is often not what the deceased would have picked on purpose, and it can lead to serious financial and legal problems for the people left behind.
In practice, two groups take the sharpest hit. Long-term unmarried partners often receive nothing under intestate law in most states, no matter the length of the relationship. Blended families can get a distribution formula that ends up setting a surviving spouse up against stepchildren from a prior marriage. If you understand how that hierarchy works, and especially where it creates results most people would not predict, it becomes clear why intestate succession is an issue you should plan around, rather than just shrug and accept.
How intestate succession works
Every state has a probate code that lays out a family inheritance ladder for people who pass away without leaving a will. In each state, that ladder starts at the closest legal relatives, and then it paces outward until a rightful heir is found. In most jurisdictions, the spouse usually inherits first, followed by any children. These people are followed by the parents, and then the siblings. If none are available, the properties go to the next set of kin. As is often with all cases concerning intestacy, rules of inheritance vary with the jurisdiction, but that’s what most jurisdictions provide.
When an individual passes on and has a spouse and children, the property first goes to the spouse and then to the children. The precise division between spouse and children differs by state. In some states, the spouse takes the entire estate if the children are also the spouse’s. In others, the spouse and children share even when the children are the spouse’s own. Anyone weighing what the situation looks like in a specific jurisdiction may find it useful to see how the outcome plays out under one state’s statute in detail.
If the deceased was married with no children, the surviving spouse typically gets the whole estate, but it can be limited by a small part for the surviving parents, depending on the situation.
If the deceased was single with children, the kids split the estate equally. And if a child passed away before the deceased, that child’s own children, meaning the deceased’s grandchildren, can step in and take the deceased child’s spot, sharing whatever that parent would have gotten.
In the event that a child dies before a parent, the grandchild or grandchildren of the deceased child could receive whatever assets or property their parent would have received.
Assets of an unmarried and childless individual will first go to the parents after their death. Then to the siblings, nieces, and nephews, and finally to more distant relatives.

Who intestate law excludes, the hardest outcomes
In nearly every U.S. state, an unmarried partner doesn’t get inheritance rights under intestate succession. This rule does not account for the relationship length, relationship contribution, or the deceased’s personal wishes. Common-law marriage recognition has narrowed a lot over recent years and only a small handful of states still let a new common-law marriage be created at all, with the exact number varying since different sources handle states with tight or recently revised rules a bit differently. Even where it is still allowed, the steps to establish a legally recognized common-law marriage are very specific.
Take, for example, a couple who lived together for twenty years and owned one home together. The home was only in one partner’s name and they shared their finances completely. In that situation, the surviving partner can still end up with nothing, while the deceased’s biological family ends up taking the estate. The surviving partner has no legal recourse under intestacy law. In states without community property protections and without a will, the outcome turns entirely on how the assets were titled.
Stepchildren typically have zero inheritance rights when a person dies without a will under intestate succession in most states, unless there was a legal adoption involved. For example, if a stepparent raised a stepchild from a young age and intended to leave them something, but then passed away without a will, the stepchild would receive nothing. In that case the estate moves over to the deceased’s biological children, their parents, or other relatives higher up in the family tree.
Some states have narrow exceptions for stepchildren who can show they would have been adopted but for a legal barrier. Unfortunately, these are not universal and require litigation to establish. The general rule across most jurisdictions is clear. Legal adoption creates inheritance rights but a parental relationship does not.
The blended family problem
Blended families end up dealing with some of the trickiest intestate succession results since the statutory formula was never made for the complex family setup that blended families have.
Think about the usual case of a second marriage, where one partner already has children from an earlier relationship. In many jurisdictions, a spouse who dies intestate means that the estate gets split between the surviving spouse and the deceased spouse’s kids from the earlier union. So the surviving spouse might walk away with roughly half and then become a reluctant co-owner of real property together with stepchildren. Keep in mind that those stepchildren have no legal duty to respect, or help, the surviving spouse’s continued stay in a shared home.
Meanwhile, the children from the prior marriage inherit property from a parent they may not have been very close to, especially in relation to their parent’s new spouse. The surviving spouse may have contributed significantly to what was built during that later marriage, but they only receive the statutory portion. The formula reflects a mathematical hierarchy but leaves out the relational reality of the family.
What intestate law does not cover
Intestate succession mostly kicks in only for probate assets, which is property the deceased owned in their name and not tied to any beneficiary designation or shared ownership with right of survivorship. In some situations, intestacy might not apply to a large portion of a “regular” estate at all.
Retirement accounts and life insurance policies usually go straight to the named beneficiary, via designation, not through the estate. Jointly owned property with survivorship goes right to the other owner automatically. Payable-on-death and transfer-on-death arrangements let them bypass probate. For families where most things have already been set up with these different kinds of mechanisms, the effect of dying without a will can end up being relatively small.
But any asset without one of these mechanisms falls into the probate estate and is distributed under the intestate formula. A bank account in only one name, a solely owned piece of real estate, or personal property with significant value can all become subject to the statutory hierarchy if no other transfer mechanism has been established.
Half-siblings and the blood relationship distinctions
Many modern jurisdictions treat half-blood relatives in basically the same way as full-blood ones, at least when it comes to inheritance. In practice a half-sibling usually receives an equal share right next to a full sibling when intestate succession occurs or when there is no will.
A handful of states still apply older rules under which half-blood relatives receive half the share of full-blood relatives in the same class, including Kentucky, Louisiana, Missouri, Texas, and Virginia. Anyone with half-siblings in states that maintain this distinction should be aware that the outcome under intestacy may not reflect the relationship they wanted those siblings to have with the estate.
What the statutory formula cannot do
Intestate succession can distribute assets. What it cannot do is reflect the actual relationships, intentions, or circumstances of the person who died. It cannot leave property to a long-term partner who was never married. It cannot guarantee that a stepchild who was raised as a biological child receives an equal share. It cannot protect a surviving spouse in a blended family from becoming a co-owner with stepchildren who have competing interests in the same property.
A will can address all of these issues. Having properly structured beneficiary designations, joint ownership arrangements, and funded trusts can also help. The legal tools that allow people to direct their assets as they choose exist and are accessible. Intestate succession applies when those tools are not used, and its outcomes are determined by statutory formulas that do not consider the individual’s life.
