How much does probate cost in Illinois compared to a trust?

Probate in Illinois typically costs 1.9-3% of the estate value in attorney fees alone (755 ILCS 5/27-2 (reasonable compensation; no statutory percentage)) — about $29,820 all-in on a $500,000 estate. A revocable trust has a one-time setup cost and no probate fees.

Can I avoid probate with just a will in Illinois?

No. A will must go through probate in Illinois. However, estates with personal property under $150,000 may qualify for Small Estate Affidavit, which is faster and less expensive than full probate (755 ILCS 5/6-4, 5/9-4 (appointment), 5/12-2, 5/12-4 (bond), 5/14-1, 5/14-2 (inventory/appraisal), 5/18-3 (creditor notice), 5/25-1 (small estate), 5/27-1, 5/27-2 (fees), 5/28-1, 5/28-2 (independent admin)).

Trust vs Will in Illinois

The will route in Illinois pays attorney fees on a reasonable-compensation basis, typically 1.9% to 3% of the estate. There's negotiation room, but probate still takes time. The trust route is a higher upfront effort (the trust has to be funded), in exchange for skipping that fee entirely. The Illinois probate calculator shows the dollar gap on your estate size; the Illinois will cost calculator covers what each provider charges to draft the will itself.

If the estate stays under $150,000 in Illinois, the will-only path is short and inexpensive — a small-estate affidavit handles the transfer without formal probate. The trust route only pulls ahead at higher estate values where probate's cost and timeline start to bite.

Beyond cost, Illinois probate is a public proceeding: the will, asset inventory, beneficiary identities, and distribution amounts all become court records. A trust keeps the same information private. For some families that's the deciding factor regardless of dollar math.

If the trust route fits, the Illinois revocable trust form handles the document. If you want a quick gut-check first, the trust need assessment walks through the size, complexity, and family-structure factors that swing the answer.
