The Short Answer
It depends on the property and family situation. If an Illinois resident dies without a valid will, Illinois intestacy law generally supplies default rules for distributing probate property. Those rules may not match what the person would have chosen.
What if There Is a Spouse and Descendants?
As a general rule, Illinois law divides the intestate probate estate between the surviving spouse and descendants when both exist. The exact distribution can depend on legal family relationships and the assets that are actually part of the probate estate.
What if There Is a Spouse but No Descendants?
Generally, a surviving spouse receives the intestate probate estate when there are no descendants. Other ownership arrangements or beneficiary designations may still control particular assets.
What if There Are Descendants but No Spouse?
Generally, descendants inherit the intestate probate estate when there is no surviving spouse. How shares are divided can depend on the family tree and whether a descendant died before the decedent.
What if There Is No Spouse or Descendant?
Illinois law then looks to other relatives in a statutory order. Which relatives inherit can become fact-specific, especially when there are deceased relatives, half-siblings, adopted children or other family-law questions.
Do Unmarried Partners, Friends or Stepchildren Automatically Inherit?
Not necessarily. Intestacy rights come from statute and legal relationships. A person who is not an heir under Illinois law does not automatically receive probate property simply because the decedent intended that result informally.
Does Dying Without a Will Avoid Probate?
No. Whether probate is needed depends on what the person owned, how the property was titled, its value and whether an effective non-probate transfer method applies.
Bottom Line
Dying without a will does not mean the State automatically receives everything, but it does mean Illinois default rules may control probate property. Because the answer depends on the family relationships and how each asset is owned, an attorney should review the specific estate before anyone relies on a general inheritance rule.
