About Illinois,
Illinois intestacy gives a spouse all when there are no descendants, or one‑half when descendants survive. A spouse may renounce a will to claim a statutory share. Illinois imposes a separate estate tax with a $4,000,000 exclusion and, effective 1/1/2026, increases homestead to $50,000/$100,000.
Illinois follows common law (equitable distribution) for property classification. This means assets are not automatically split equally -- ownership depends on title, and probate distribution follows intestate statutes or the will.
Without a will, Illinois intestate law (755 ILCS 5/2-1) determines your share. The small-estate threshold is $150,000, and typical probate takes 6-12 months for a simple, uncontested probate..
Illinois imposes a state-level estate tax, which may affect larger estates and require additional filing deadlines beyond federal requirements.
