Who Inherits When There Is No Will in Illinois
Here is exactly how Illinois divides an estate when there is no will:
| If the person leaves… | Who inherits in Illinois |
|---|---|
| Spouse, no children | The surviving spouse inherits 100% of the intestate estate (755 ILCS 5/2-1(c)) |
| Spouse + shared children | The surviving spouse inherits 1/2 of the estate; the descendants share the other 1/2 per stirpes. Illinois does NOT give the spouse a larger share when all children are also the spouse’s — the split is always 1/2 and 1/2 whenever any descendants exist (755 ILCS 5/2-1(a)) |
| Spouse + children from another relationship | Same as shared children — the surviving spouse inherits 1/2 and the decedent’s descendants share the other 1/2 per stirpes. Illinois makes no distinction based on whether the children are also the spouse’s children (755 ILCS 5/2-1(a)) |
| Children, no spouse | The descendants inherit 100% of the estate, divided per stirpes (755 ILCS 5/2-1(b)) |
| No spouse, no children | The estate passes to parents, brothers, and sisters in equal parts. If one parent is deceased, the surviving parent receives a double portion. Descendants of a deceased sibling take per stirpes that sibling’s share. If no parents or siblings or their descendants survive, the estate splits 1/2 to maternal grandparents (or their descendants) and 1/2 to paternal grandparents (or their descendants). If one side has no surviving takers, the other side takes all. The same pattern continues to great-grandparents and their descendants. If still no takers, the estate passes to the nearest kindred in equal degree without representation (755 ILCS 5/2-1(d) through (g)) |
| No living relatives (escheat) | If no surviving spouse and no known kindred exist, real estate escheats to the county where it is located; personal estate physically in Illinois escheats to the county of the decedent’s residence (or the county where located if the decedent was not an Illinois resident); all other personal property escheats to the State and is delivered to the State Treasurer under the Revised Uniform Unclaimed Property Act (755 ILCS 5/2-1(h)) |
These shares come from Illinois intestate-succession law (755 ILCS 5/2-1 (Probate Act of 1975, Article II — Rules of Descent and Distribution)).
How Illinois divides shares among descendants: Illinois uses per stirpes distribution — each line of descent takes an equal share, and if a descendant predeceases the decedent, that person’s own descendants step into their position and split that share
Illinois homestead and family allowance: The surviving spouse receives a family allowance for support for 9 months after death, no less than 20000; each minor child residing with the surviving spouse receives no less than 10000 additional; each minor child not residing with the surviving spouse receives a separate award of no less than 10000 for 9 months of support.
These awards are exempt from judgments, garnishment, and attachment, and are paid on top of the intestate share before creditors (755 ILCS 5/15-1). The Illinois homestead exemption protects up to 50000 per individual or 100000 for jointly owned property (735 ILCS 5/12-901)
Half-blood relatives in Illinois: Illinois draws no distinction between kindred of the whole blood and the half blood — half-siblings inherit identically to full siblings (755 ILCS 5/2-1, explicit statutory provision)

Assets That Pass Outside Illinois Intestate Rules
Assets with named beneficiaries (life insurance, retirement accounts, payable-on-death accounts), property held in joint tenancy with right of survivorship, and assets in a living trust pass outside Illinois intestate succession rules and are not governed by 755 ILCS 5/2-1
Other Illinois intestacy rules: Illinois has a distinctive double-portion rule: when the estate passes to parents and siblings under 755 ILCS 5/2-1(d), if one parent is deceased the surviving parent receives a double share compared to each sibling. Also, Illinois escheat uniquely goes to the county (not directly to the state) for real and personal property located in Illinois.
The surviving spouse’s family allowance minimum of 20000 is paid regardless of whether the decedent died testate or intestate and takes priority over most creditor claims
What Dying Without a Will in Illinois Really Means
When someone dies without a will in Illinois, the state’s intestate-succession law — not the family — decides who inherits. The shares above show exactly how Illinois divides an estate when someone is dying without a will in Illinois, and they often surprise people: a spouse may not automatically inherit everything.
Understanding dying without a will in Illinois helps a family know what to expect before they walk into probate court. Remember that some assets pass outside these rules entirely, so the full picture of dying without a will in Illinois depends on how each asset was titled.
