Creating a will in Illinois ensures that the Illinois probate courts will distribute your assets according to your wishes after your passing. However, you must do more than simply jot down your testamentary documents on paper in order for the judiciary to enforce them. 

Your will in Illinois must meet specific legal requirements to be valid. You must have been of sound mind and over 18 years old when drafting and executing it. You must also have two witnesses sign the document in front of a notary. 

If these requirements are not met, the courts may invalidate your will, leaving your real property and assets to be distributed according to Illinois intestate laws, rather than left to your desired heirs and beneficiaries.

How To Make a Will in Illinois?

Drafting and properly executing a valid will in Illinois is an essential step in estate planning. The drafting process can be done by a licensed state attorney or by yourself with the help of an attorney-reviewed template, like the one found at Lawrina

According to Illinois Probate Code (755 ILCS Art. 5 of the Probate Act of 1975), a testator or testatrix (the person making the will) must be an adult who holds the requisite testamentary capacity (mental capacity) to draft their estate planning documents. Your will in Illinois must also be in writing, and you must execute (sign) the legal document in the presence of witnesses who are not beneficiaries of your estate.

After properly executing your will, you must store it in a safe place and inform the executor (the named person responsible for carrying out the will’s instructions) where you stored the document. The law also demands that the testator or testatrix reviews and updates the will periodically to reflect any changes in personal circumstances or distribution of asset changes.

Finally, your testamentary document must comply with the strict legal requirements outlined in 755 ILCS Art. 5. Seeking the assistance of an attorney can help ensure that your will in Illinois is properly drafted and executed and in compliance with the legal requirements.

Requirements For a Will To Be Valid in Illinois

The following information summarizes the state’s probate codes for drafting a valid and enforceable will in Illinois.

Executor selection

The executor selection provision of a will in Illinois designates the person or business entity responsible for carrying out the instructions in the document. Also known as a “personal representative,” the executor will manage your property held in probate, pay any outstanding debts and taxes, and distribute the remaining assets to your heirs and beneficiaries according to your will's instructions. The executor must also file your will in Illinois probate court immediately after your passing and defend your “original intent” against any disputes or challenges related to your estate. Therefore, choosing a trustworthy executor capable of performing such complex tasks is crucial.

Determine your beneficiaries and heirs

Beneficiaries and heirs of a will in Illinois are individuals or organizations who will receive the remaining assets from your estate. Heirs are family members who you name in your will in Illinois or who will automatically inherit if you die intestate (without a wholly valid will in Illinois). When drafting your testamentary documents, the law requires you to “know the natural objects of your bounty.” In other words, you must determine which beneficiaries and heirs will take from your estate and understand how your decisions will affect those not named in your will (otherwise known as disinherited persons). Your will in Illinois must also clearly identify each beneficiary and the specific property or assets they will receive.

Name a guardian for minors and dependents

When drafting a will in Illinois, you must also consider the needs of any children or dependents in your estate. Designating a guardian for them ensures that your loved ones will be cared for in the event of your death. Without guardian designation, the court may appoint someone to look after your children or dependents, which may not align with your last wishes. When selecting a guardian, you should choose a responsible person who shares your values and can take care of your children.

Assess and divide your property

According to 755 ILCS Art. 5, §4-1, a testator or testatrix drafting a valid will in Illinois must “recognize the nature and scope” of their estate assets and real property (but not necessarily the full value) to be distributed. This means you must accurately assess and divide your property in your will in Illinois when planning your estate. The assessment and distribution sections of a will are important because they allow you to disperse your estate as you wish. 

Estate assets may include:

  • Personal property;

  • Bank accounts;

  • Real property;

  • Retirement accounts; and

  • Stocks or bonds.

Clearly identifying who benefits from your will in Illinois after you pass away helps prevent will contests or litigation during probate. Additionally, it can mitigate estate taxes and other expenses, ensuring that your loved ones will receive more of your property.

Let your funeral wishes be known

Informing your executor about your burial wishes is important when drafting a will in Illinois. You can ensure that your funeral arrangements follow your religious beliefs and preferences by including specific instructions. Your will in Illinois can further comfort loved ones during difficult times and prevent disagreements about funeral arrangements. The burial disclosure section also alleviates the financial burden on family members because this provision in the will in Illinois can direct the estate to use its own assets to pay for funeral expenses.

Sign the document

You must sign and notarize your will in Illinois to make it legally binding. Notarization helps prevent probate disputes by showing that the testator or testatrix was of sound mind when executing the will. Notarization involves verifying your identity and ensuring you signed the testamentary document of your own free will, without fraud or undue influence.

What Is a Handwritten Will?

A handwritten will in Illinois is a testamentary document written by the testator’s hand. The courts will only consider a handwritten will In Illinois valid if it meets certain requirements, such as being entirely in the testator's handwriting, signed by the testator, and witnessed according to 755 ILCS Art. 5, §4-3. Handwritten wills without witness attestation are known as holographic wills and are invalid under Illinois law.

Is a Handwritten Will Valid in Illinois?

As mentioned above, Illinois probate courts will accept handwritten wills under certain conditions. The State’s Probate Act of 1975 makes no reference to how testamentary documents should be written, meaning any will writing (by machine or hand) that is appropriately signed and witnessed is valid under the law.

While handwritten wills may be legally valid in Illinois, better estate planning options are available. Handwritten wills are often difficult to read or interpret, and they may not include all the necessary components required by 755 ILCS Art. 5. Additionally, handwritten wills in Illinois are generally subject to greater challenges or probate disputes when compared to machine-typed documents.

Therefore, the law recommends that you have an estate attorney review a handwritten will in Illinois before execution to ensure that the document is legally valid and clearly expresses your last wishes.
