What Happens When Someone Dies Without a Will in Illinois?
Every year, thousands of Illinois residents die without a will. Dying “intestate” does not mean assets will be distributed according to what the person would have wanted. It means assets will be distributed according to what the Illinois legislature decided decades ago — in a law that knows nothing about the individual’s family, relationships, or wishes.
Illinois Intestacy Law: The Basic Rules
When an Illinois resident dies without a valid will, their probate estate is distributed under the Illinois Probate Act of 1975, Article II (755 ILCS 5/2-1 et seq.):
- Married with children: Spouse receives one-half; children receive the other half equally. A surviving spouse does not automatically receive the entire estate — they share it with the children, regardless of the children’s ages or the practical effect on the family.
- Married, no children: Surviving spouse receives the entire estate.
- Unmarried with children: Children receive the entire estate equally (or by representation to grandchildren).
- Unmarried, no children, living parents: Parents receive the entire estate.
- No spouse, children, or parents: The estate passes to siblings, then to grandparents and their descendants, following the specific order in the Illinois statute.
What Intestacy Does Not Cover
Illinois intestacy law does not recognize: unmarried partners (regardless of the length or nature of the relationship), stepchildren (not legally adopted), close friends, caregivers, charities, or any person outside the statutory hierarchy. If your primary relationship is with an unmarried partner of twenty years, that person receives nothing under Illinois intestacy law. Everything goes to biological relatives, no matter how distant, before an unmarried partner receives a dollar.
Real Problems That Intestacy Creates
Minor Children
If your children are minors and there is no surviving parent, Illinois intestacy law provides no mechanism for choosing who raises your children or manages their inheritance. A court will appoint a guardian of the person and a guardian of the estate — and those two roles may be filled by different people. The inheritance will be managed under court supervision until the child turns 18, at which point the child receives the full amount outright, with no restrictions and no guidance. A will with a testamentary trust for minor children solves all of these problems: it designates a guardian, names a trustee, sets distribution terms, and specifies when the child receives the balance outright.
Blended Families
For blended families, intestacy produces results that almost no one would want. Stepchildren receive nothing; only biological and legally adopted children inherit. A surviving spouse in a blended family shares the estate with the deceased spouse’s biological children from prior relationships, who may be adults with no financial need. The surviving spouse’s ability to remain in the family home may be compromised if the estate must be partially liquidated to pay out the biological children’s shares.
Business Interests
If you own an interest in a closely held business, dying without a will or a buy-sell agreement can be catastrophic. Under intestacy law, your business interest passes to your heirs — who may have no relationship with your business partners, no interest in the business, and every incentive to force a liquidation or sale. Your partners may find themselves unable to operate the business without consent from people who had no prior involvement in it.
Estate Tax
Intestate estates cannot be structured to minimize Illinois or federal estate tax. The bypass trust strategy that allows a married couple to use both spouses’ $4 million Illinois exemptions requires a will or revocable trust with specific provisions. Dying intestate with an estate above $4 million means forfeiting the first-to-die spouse’s exemption entirely — a potentially six-figure tax cost that proper planning would have avoided.
The Minimum Illinois Estate Plan
At a minimum, every Illinois adult should have: (1) a will naming an executor, designating guardians for minor children, and directing asset distribution; (2) a durable power of attorney for property to authorize financial management during incapacity; and (3) a healthcare power of attorney to designate a healthcare decision-maker. These three documents address the most critical gaps left by dying intestate or becoming incapacitated without authorization documents.
For most families, a revocable living trust is a significant improvement over a will alone: it avoids probate, provides a more comprehensive incapacity plan, protects privacy, and includes detailed provisions for children, disabled beneficiaries, and tax planning. But even a basic will is infinitely better than no plan at all.
The question is not whether you have enough assets to need an estate plan. The question is whether you have people in your life who depend on your decisions — a spouse, children, a partner, a disabled family member, a business partner. If you do, those people deserve a plan that reflects your wishes rather than one drafted by the Illinois legislature for the average family in 1975.
