Illinois Last Will and Testament Laws and Requirements

A last will and testament in Illinois must meet specific statutory requirements to be valid and enforceable in probate court. The testator must properly execute the document with the correct number of witnesses to ensure it directs the distribution of estate assets to named beneficiaries and appoints an executor to administer the estate. Illinois requires two credible witnesses at least 18 years old must attest the testator's signature. Illinois does not recognize holographic (handwritten) wills — not recognized — Illinois requires all wills to be witnessed. available — testator and witnesses sign a self-proving affidavit before a notary under 755 ILCS 5/6-4

Without a valid will, Illinois intestate succession laws determine who inherits — often in ways that contradict the decedent's wishes. A surviving spouse may receive only a portion of the estate, unmarried partners receive nothing, and a court appoints an administrator instead of the testator's chosen executor. Proper execution under Illinois law prevents these outcomes and reduces the risk of a will contest. A complete estate plan typically pairs a will with a power of attorney for lifetime incapacity protection.

Illinois Last Will and Testament FAQ

How many witnesses do I need for a will in Illinois?
In Illinois, two credible witnesses at least 18 years old must attest the testator's signature. Witnesses should be "disinterested" — meaning they are not beneficiaries under the will, as a beneficiary-witness may forfeit their inheritance under Illinois law.
Does Illinois recognize holographic (handwritten) wills?
Not recognized — Illinois requires all wills to be witnessed. Even where permitted, a formally witnessed will is always more reliable because it is harder to contest. Use our will generator to create a properly formatted, witnessed document.
Does a will need to be notarized in Illinois?
In Illinois: not required for the will itself, but required for the self-proving affidavit. A self-proving affidavit eliminates the need for witnesses to testify in probate court, which significantly speeds up the process.
What happens if you die without a will in Illinois?
If you die without a will (intestate) in Illinois, state intestacy laws determine who inherits. Typically, your spouse and children inherit in proportions set by Illinois statute. Unmarried partners, close friends, and charities receive nothing. A Illinois court will appoint an administrator and, if you have minor children, a judge decides guardianship. This process is public, slow, and costly. Download our last will template to prevent this.
