The most common estate plan in Illinois is a very sincere piece of paper.
A note in a desk drawer. A letter in a safe. Written out carefully, in the person's own hand, signed and dated, saying exactly who gets what — and meaning every word of it.
Illinois will not admit it to probate.
The handwriting isn't the problem. You can absolutely write your own will in Illinois, longhand, on whatever paper is nearby. The Probate Act asks for three things: it has to be in writing, you have to sign it, and two credible witnesses have to attest it in your presence.
It's the third one people miss. A will written entirely in your own hand and signed, but not witnessed — a holographic will — is valid in a lot of states. Illinois is not one of them. Without the two witnesses, the estate passes under the intestacy rules, whatever the paper says.
Three things that surprise people:
Notarizing it doesn't fix it. A notary isn't a witness, and notarization isn't on the list. A notarized self-proving affidavit is still worth having — it saves your witnesses a trip to court later — but it doesn't replace them.
Both witnesses have to be there while you sign, and sign while you're there. Signing separately, or later, doesn't count.
A beneficiary can technically witness, but risks forfeiting what you left them. Pick two people who aren't in the document.
And you can't amend a will by crossing something out or writing in the margin. Changes need the same ceremony the original did.
None of this is hard. It's about fifteen minutes and two people. It just has to actually happen.
We draft wills on a flat, upfront fee, quoted before we start, with the signing handled properly — so the document works the way you meant it to.
Honest question: is there a version of this note in a drawer at your house right now?
