Wills and Trusts in Illinois: The Basics, Without the Jargon

A will says who gets what. A trust is a way of holding property for someone else. The difference, in plain English, for Illinois families.

Wills Trusts  ·  September 17, 2026

Two words that put people off doing something important. Here is what each one means.

A will

A will is a document saying who receives what you own after you die, and who looks after any children who are still minors. Without one, Illinois law decides both, using a fixed order that may not match what you would have chosen.

Example. A couple own a home and have two young children. Their will can name who raises the children and who manages money on their behalf until they are adults. Without a will, a court decides.

Probate

Probate is the court process that confirms a will and oversees passing things on. It can be slow, it costs money, and the file is public. Shortening or avoiding it is why many people look at trusts.

A trust

A trust is an arrangement where one person or institution holds property on behalf of someone else. A common type is a living trust: you move assets into it while alive, manage them yourself, and name who receives them afterwards.

The usual attraction is that assets in a trust can pass without probate, privately and often faster. The trade-off is that a trust costs more to set up and only works if it is actually funded, meaning the assets are properly moved into it. An unfunded trust helps nobody.

Who needs what

• Almost every adult benefits from a will, especially anyone with children.
• A trust is worth exploring if you own property, have assets in more than one state, want privacy, or are providing for someone who needs long-term support.
• Beneficiary forms matter. Retirement accounts and life insurance usually pass by the beneficiary named on the account, not by the will. Out-of-date forms are one of the most common and most painful mistakes.

Important

Estate rules differ by state and change over time. This article describes general Illinois concepts and is not legal advice. This is the one topic on our Money Matters hub where an hour with an Illinois-licensed attorney is usually money well spent.
