Illinois Estate Planning: Wills, Trusts & Probate

Illinois probate is handled at the county circuit court level and, while not the most expensive in the country, still commonly takes the better part of a year, making small-estate affidavits and trusts attractive for many Illinois families.

Illinois at a glance

Will witnesses

2 required

Illinois requires two credible witnesses who sign in the testator's presence, ideally disinterested (not beneficiaries) to avoid complications.

Self-proving affidavit

See details

Illinois allows a self-proving affidavit notarized at signing, which streamlines admitting the will to probate without live witness testimony.

Remote online notarization

Permitted by state law

Illinois authorizes remote online notarization by Illinois-commissioned notaries for most documents. LegacyShield remote notary sessions are coming soon — in-home notary visits are available now.

Typical probate

9–12 months minimum, since Illinois requires a claims period of at least 6 months after notice to creditors before the estate can close.

Illinois has no statutory percentage fee schedule; attorney fees are typically hourly or flat-fee, with routine independent administration often costing $3,000–$8,000 in legal and court fees for a moderate estate.

Small-estate threshold

$100,000 in personal property (and no real estate other than certain transferable interests)

The Illinois Small Estate Affidavit lets a representative collect and distribute qualifying estates without opening full probate.

Property regime

Common law

Illinois is a common-law property state. Each spouse owns what's titled in their name, though a surviving spouse can elect a statutory share (generally one-third if there are descendants, one-half if not) instead of what a will provides.

Healthcare directives in Illinois

Illinois uses a Health Care Power of Attorney to appoint an agent and a separate Illinois Living Will for end-of-life instructions (or a combined statutory form). One witness plus notarization, or two witnesses, is generally accepted depending on the form used.

Powers of attorney in Illinois

Illinois's statutory short-form Power of Attorney for Property requires the principal's signature witnessed by one adult witness and notarized; using Illinois's statutory form language provides broader legal protection and acceptance by institutions.

Illinois estate planning questions

Why does Illinois probate take at least 6 months?
Illinois law requires a minimum 6-month claims period after creditors are notified, during which they can file claims against the estate, before the estate can be closed — this is a statutory floor regardless of complexity.
What is independent administration in Illinois?
It's a streamlined process (available when the will authorizes it or heirs consent) that lets the executor act without seeking court approval for most routine steps, reducing legal fees and delay compared with supervised administration.
Can my spouse contest my will in Illinois?
A surviving spouse can renounce the will and take a statutory share (one-third with descendants, one-half without) instead of what the will provides, so disinheriting a spouse entirely is generally not effective.
Does Illinois allow electronic wills?
Illinois has adopted electronic wills legislation with specific execution and storage requirements — work with a compliant platform or attorney if you want to sign electronically.

Laws change and every estate is different — verify current requirements with a licensed attorney in your state before signing or relying on any document.
