Most people assume their house will automatically go to their spouse or children when they die. In Illinois, that is not always the case, especially without a will.
Dying without a will and owning a house puts the property under a set of state rules that most families have never read. Those rules decide who inherits, how much each person gets, and how long the process takes.
This guide explains what happens in that situation, from Illinois intestate succession rules to the probate steps that follow. It also answers the practical question many families face: who inherits a house without a will, and what can they do with it?
This article is general information, not legal advice. If you are dealing with real estate after a death, talk to an Illinois probate attorney about your specific facts.
What Does It Mean to Die Intestate?
Dying without a valid will is called dying intestate. When that happens, Illinois law decides who receives the person’s property, not the family and not the deceased person’s wishes.
The rules come from the Illinois Probate Act, specifically 755 ILCS 5/2-1. That section sets a fixed order of heirs, starting with the spouse and children and moving outward.
Dying without a will and owning a house is more common than most people think. Many homeowners put off estate planning, or they assume a spouse or child will simply take over.
Intestate does not mean the state takes everything. In most cases, the property goes to relatives, just not necessarily the relatives the owner would have chosen.
Intestate Succession in Illinois: Who Inherits?
Intestate succession in Illinois follows a strict priority order. The estate is first used to pay valid debts and expenses, and what remains passes to heirs in this order:
#1 Spouse and descendants: the spouse receives one-half, and the children, grandchildren, and other descendants share the other half.
#2 Descendants only: if there is no surviving spouse, the descendants share the entire estate.
#3 Spouse only: if there is a spouse but no descendants, the spouse receives the entire estate.
#4 No spouse or descendants: parents, brothers, sisters, and the descendants of deceased siblings share in equal parts.
#5 Grandparents and their descendants: if none of the above survive, the estate moves to more distant relatives.
#6 Great-grandparents and nearest kindred: the search continues outward through the family tree.
#7 No known relatives: the real estate passes to the county where it sits, which is called escheat.
The word “descendants” includes children, grandchildren, and great-grandchildren. When a child has died, that child’s share generally goes to the child’s own descendants, which lawyers call per stirpes, meaning by family branch.
Illinois does not treat half-blood relatives differently from whole-blood relatives. A half-sibling generally receives the same share as a full sibling.
Adopted children inherit like biological children. A child born outside of marriage always inherits from the mother and can inherit from the father in certain circumstances.
For a plain-language overview, Nolo publishes a helpful summary of intestate succession in Illinois. It is a good companion to the statute itself.
Who Inherits a House Without a Will? Common Scenarios
The abstract rules matter less than how they play out for a real family. Here is who inherits a house without a will in the most common situations.
Married with children. Many people are surprised to learn the surviving spouse does not receive everything. If there are children, the spouse gets half of the estate, and the children split the other half.
Take a $240,000 home that is the only significant asset. With a spouse and two children, the spouse gets half, and each child gets one quarter, and the same split applies even when the children are from a prior relationship.
That rule can hurt blended families. A stepparent who lives in the home may own only half, while the deceased spouse’s adult children own the rest.
Married with no children. The surviving spouse inherits the entire estate. This is the simplest outcome under Illinois intestate succession.
Unmarried with children. The children share the house equally, with a deceased child’s share going to that child’s own children.
Unmarried with no children. The house passes to parents, siblings, and siblings’ descendants, then further out if none survive. Whoever is closest in the family tree ends up owning the property.
Unmarried partners. This is the hardest situation. Under Illinois intestacy law, a partner who is not legally married inherits nothing, no matter how long the couple lived together.
So who is next of kin if there is no will? In Illinois, it is the person or people highest on the statutory list above, not whoever the family assumes should get the house.
Does Someone Have to Go Through Probate?
Usually, yes. If the house was owned in the deceased person’s name alone, it generally must go through probate, the court process that identifies heirs, pays debts, and transfers ownership.
This is a common trap when you die without a will and own a house. People think a small or paid-off home can skip court, but real estate is the one asset that usually cannot.
Illinois allows a small estate affidavit for estates with $150,000 or less in personal property, but the property must not include real estate. The Illinois Secretary of State publishes a sample affidavit, and it applies to personal property, not houses.
A few situations let a house pass outside probate:
#1 Joint tenancy with right of survivorship, where the surviving owner automatically takes the property.
#2 Tenancy by the entirety between spouses, where available.
#3 A recorded transfer-on-death instrument that names a beneficiary.
#4 A house already titled in a living trust.
If none of these apply, expect a court process. That is the default outcome for dying without a will and owning a house in one person’s name.
The Probate Process for an Intestate Estate
Probate can feel confusing, but it follows a predictable path. Here are the main steps when there is no will:
#1 A family member files a petition for letters of administration in the circuit court of the county where the person lived.
#2 The court determines the legal heirs based on the intestate rules.
#3 The court appoints an administrator and may require a bond.
#4 The administrator gives notice to heirs and publishes notice to creditors.
#5 Creditors generally have six months from the first publication to file claims.
#6 The administrator inventories assets, pays debts and expenses, and handles the house.
#7 The administrator distributes what remains to the heirs and closes the estate.
Timing varies. Nolo notes that most Illinois probate cases finish in about a year, and the six-month claims period sets a floor for how quickly the estate can close.
For more detail, see Nolo’s Illinois probate overview. It explains independent administration, which lets the administrator act with less court oversight.
Who Becomes the Administrator?
With no will, no one is named as executor. Instead, the court appoints an administrator, usually preferring the surviving spouse and then adult children, though the court has discretion.
The administrator has real responsibilities. They must protect the property, keep records, pay valid debts, and treat every heir fairly.
Because there is no will to waive it, the court may require the administrator to post a bond. That is a kind of insurance that protects the estate if something goes wrong.
Being named administrator does not make someone the owner of the house. The heirs still own the property under the statute, and the administrator is managing it on their behalf.
What Happens to the Mortgage and Other Debts?
Debts do not disappear when someone dies. A mortgage remains attached to the house, and the loan must still be paid, or the lender can foreclose.
Heirs generally take the property subject to existing mortgages and liens. Federal law does limit a lender’s ability to call a loan due just because the owner died and a relative inherits, but payments must continue.
In practice, someone needs to keep paying the mortgage, taxes, and insurance while probate is pending. Missed payments can cause serious problems, even if the family is unsure who legally owns the house.
If the home is falling behind, read our page on how to sell a house in foreclosure in the Chicago Southland. Acting early gives you more choices.
Unpaid property taxes also follow the property. Our guide to property taxes when selling a house explains how they are handled at closing.
Illinois also has an estate tax with a $4 million exemption for deaths in 2026, according to Nolo. Most families are far below that level, but very large estates should get professional tax advice.
When Several Heirs Own the House Together
One of the biggest headaches after dying without a will and owning a house is shared ownership. If a spouse and two children inherit, or if five siblings inherit from a parent, they all own the property together.
For major decisions, including selling, everyone generally must agree. One heir who wants to keep the house can block heirs who want cash.
Disagreements are common. Someone may live in the house rent-free, someone may pay all the bills, and someone else may want to sell right away.
If heirs cannot agree, one option is a court action to force a sale or division, called partition. It is expensive, slow, and often damaging to family relationships.
If this sounds familiar, our articles on selling a house with family conflict and family disagreements when selling an inherited house offer practical guidance.
Can You Sell the House Before Probate Is Finished?
Many families ask this, and the answer depends on who has legal authority. Heirs generally cannot sell a house they have not yet been legally established as owning.
Once the court appoints an administrator, that person can manage the estate’s property. Under independent administration, an administrator can often sell real estate with fewer court steps, but the details depend on the case.
Buyers and title companies will want to see proof of authority before closing. That usually includes the court’s letters of office and documents showing the legal heirs.

Tax Basics for Heirs
Inheriting a house usually comes with a tax benefit. Property received at death generally gets a basis equal to its fair market value on the date of death, which can greatly reduce taxable gain if the heirs sell soon after.
That differs greatly from receiving a house as a gift while the owner is alive. See IRS Publication 551 for how basis works, and IRS Publication 559 for guidance aimed at survivors, executors, and administrators.
Keep records of the home’s value at the date of death. A professional appraisal often helps if the heirs plan to sell.
Ongoing costs matter too. Property taxes, insurance, utilities, and repairs continue during probate, and a vacant home may need special insurance coverage, so contact the insurance company early.
How to Avoid This Situation
The best way to avoid dying without a will and owning a house is to plan ahead. Even a simple estate plan gives you control over who receives the property.
Here are the main tools Illinois homeowners can use:
#1 A will, which names your heirs and an executor, although the house still goes through probate.
#2 A transfer-on-death instrument, which passes the house to a named beneficiary without probate.
#3 A living trust, which holds the home and names the recipient.
#4 Joint ownership with survivorship, which can work for spouses but carries risks for other relationships.
The transfer-on-death instrument is popular in Illinois. Under the Real Property Transfer on Death Instrument Act, an Illinois attorney must prepare it, and you must record it before the owner’s death.
You keep full control during your life, and you can revoke the instrument. If you are a homeowner reading this, that alone is a strong reason to talk to an attorney.
If You Have Already Inherited a House With No Will
If you are on the other side of this, taking the right steps early makes everything easier. Here is a sensible order to follow:
#1 Secure the property and make sure it is insured and locked.
#2 Locate any will, trust, deed, or transfer-on-death instrument, since one may exist.
#3 Keep the mortgage, taxes, and utilities current.
#4 Talk to an Illinois probate attorney about opening the estate.
#5 Gather the deed, mortgage statement, tax bills, and death certificate.
#6 Talk openly with the other heirs about whether to keep, rent, or sell.
Don’t move in, rent out, or sell the property until you understand who legally owns it. Acting too early can create problems with other heirs.
If the home has tenants, our page on how to sell a tenant-occupied rental in the Chicago Southland explains what buyers look for.
Should You Keep or Sell the House?
Once ownership is clear, families face a big decision. Keeping the house sounds good emotionally, but it can become a financial and emotional burden.
Consider the carrying costs, the repairs, and whether anyone actually wants to live there. Waiting too long can hurt, as we explain in our article on waiting too long to sell a house.
Inherited homes often have hidden problems, from deferred maintenance to unclear title. Our article on selling a house with hidden problems can help you plan.
If a fast, simple sale appeals to you, read is a cash sale right for me and what to expect when selling a house for cash. A cash sale can let heirs split the proceeds cleanly instead of co-owning a property they did not plan on.
Be sure to understand the costs too. Our post on who pays closing costs shows how those fees are usually divided.
Final Thoughts
Dying without a will and owning a house leaves the outcome to state law. Intestate succession in Illinois protects close family, but it often produces results the owner never intended.
To recap, a spouse does not always inherit everything, unmarried partners inherit nothing, and a house owned in one person’s name almost always goes through probate. Families who know who inherits a house without a will can plan more calmly and avoid costly mistakes.
If you are the owner, a simple plan now can save your family months of court and thousands of dollars. If you are the heir, move carefully and get legal guidance before making decisions about the property.
