Self-Proving Affidavit in Illinois Wills: What It Is and Why It Matters
A self-proving affidavit is a notarized statement by your will’s witnesses confirming they watched you sign. In Illinois, it is not required for a valid will, but it can let a court admit your will to probate without your witnesses testifying. Illinois also allows a signed attestation clause to do the same job. Key takeaways- A valid Illinois will needs writing, your signature, and two credible witnesses.
- A self-proving affidavit is optional in Illinois, not required for validity.
- It can let a court admit your will without witness testimony.
- Illinois also accepts a signed attestation clause, sometimes without a notary.

What is a self-proving affidavit?
A self-proving affidavit is a short, notarized statement from your will’s witnesses confirming they watched you sign. It travels with the will, so a court can accept their account later without calling them in. In Illinois, it’s a convenience, not a condition of a valid will. Two tools get confused. An attestation clause is the paragraph above the witness signatures stating what they saw. The affidavit is a separate statement, sworn before a notary public. Under the Illinois Probate Act of 1975 (755 ILCS 5/), either one can replace live testimony when your will is offered for probate.Does Illinois require a self-proving affidavit?
No. Illinois does not require a self-proving affidavit for your will to be valid. A will is fully valid here without one and without a notary. The affidavit changes how your will is proved, not whether it counts. Validity asks whether the will is good; proof asks how easily a court accepts it after you die.
Illinois will requirements (two credible witnesses)
In Illinois, a valid will needs three things: writing, your signature as the testator (the person making it), and two credible witnesses under 755 ILCS 5/4-3. A credible witness, also called an attesting witness, watches you sign and then signs in your presence. Under 755 ILCS 5/4-1, you must also be at least 18 and of sound mind to make a will in Illinois.Does an Illinois will need a notary?
No. An Illinois will doesn’t need to be notarized to be valid. A notary public matters only if you add a self-proving affidavit. The Illinois State Bar Association notes that proper signing and witnessing is what makes a will hold up. What most articles miss: Illinois lets a signed attestation clause self-prove a will without a notary at all.How a self-proving affidavit changes Illinois probate
| Method | What it covers | Notary? | Witnesses appear later? |
|---|---|---|---|
| Attestation clause signed by witnesses | Proper signing and witnessing | No | Usually no |
| Notarized self-proving affidavit | A sworn version of the same facts | Yes | Usually no |
| Live witness testimony in court | Witnesses prove the will in person | No | Yes |
| Formal proof of will — contest | Court re-examines execution | n/a | Yes, testimony or deposition |
How to make your Illinois will self-proving
To make your will self-proving, add a signed attestation clause or a notarized affidavit when you sign. Under 755 ILCS 5/6-4, either one lets the court accept your witnesses’ account without calling them in. The usual steps:- Put your will in writing and read it carefully before signing.
- Sign in front of two credible witnesses, as 755 ILCS 5/4-3 requires.
- Have both witnesses sign an attestation clause describing what they saw.
- For the sworn version, sign before a notary public.
- Keep the affidavit with your will, and store the original somewhere safe.
Does a self-proving affidavit prevent a will contest?
No. A self-proving affidavit does not prevent a will contest in Illinois. It speeds routine admission but does not settle claims of fraud, undue influence, or lack of capacity. If someone challenges the will, the case can move to a formal proof of will hearing, where the court re-examines the will’s execution and your witnesses may need to testify or give a deposition. In Cook County, a will is filed with the Cook County Circuit Court Probate Division at the Richard J. Daley Center, 50 W. Washington St. in Chicago. An Evanston, Illinois resident’s will is filed there, since Evanston sits in Cook County. When a contest is likely, careful drafting matters more than any affidavit, and Illinois probate services can help your family respond.Adding a self-proving affidavit to an older or out-of-state will
You can often make an older Illinois will self-proving, and you can usually update a will you brought from another state. This is typically handled by re-executing the will with a compliant clause or affidavit, not by editing the original yourself. If you signed your will in another state and later settled in Wilmette or Winnetka, it may already be valid in Illinois but not self-proving here. An Illinois-licensed attorney can confirm whether it needs an updated clause or affidavit.Frequently asked questions about self-proving affidavits in Illinois
- Is my Illinois will valid without a self-proving affidavit?
-
Yes. An Illinois will is valid when it's in writing, signed by you, and witnessed by two credible witnesses under 755 ILCS 5/4-3. The affidavit affects only how the will is proved.
- Does a will need to be notarized in Illinois?
-
No, not for validity. A notary is used only when you add a self-proving affidavit. A signed attestation clause can self-prove an Illinois will without a notary.
- Can I add a self-proving affidavit to an existing will?
-
Often, yes. It's usually done by properly re-executing the will or adding a compliant attestation clause or affidavit. An Illinois attorney can confirm the right method for you.
- Does a self-proving affidavit prevent a will contest in Illinois?
-
No. It eases routine admission to probate, but it doesn't bar a will contest. A challenged will can still go to a formal proof of will hearing.
- What happens if my will witnesses can't be found?
-
A self-proven will can still be admitted in routine cases, even when witnesses are gone. If the will isn't self-proving, the court may allow depositions or other proof that it was signed correctly.
- Do all states require a self-proving affidavit?
-
No. Rules vary by state. Many require a separate notarized affidavit, while Illinois also accepts an attestation clause. Have any out-of-state will reviewed under Illinois law.
