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.
