In Illinois, estates with personal property of $150,000755 ILCS 5/25-1Verified Sep 8, 2026View source or less skip probate with the Small Estate Affidavit755 ILCS 5/25-1Verified Sep 8, 2026View source. That route is a form rather than a court case, and most families handle it without an attorney. Above the line, formal probate generally benefits from counsel for the procedural work, even when nothing is contested. The Illinois probate calculator estimates the cost by estate value.

In Illinois, the situations where counsel is typically worth the cost are: a blended family with children from a prior relationship; a business, rental property or significant investment assets; a dependent with special needs, who needs a special-needs trust to keep benefits; an estate near or above the Illinois estate tax35 ILCS 405/2Verified Sep 15, 2026View source threshold of $4,000,00035 ILCS 405/2Verified Sep 15, 2026View source; substantial property in more than one state. Where none of these apply, an online or self-help document is often enough.

Filter the directory by county and by the practice area you need, and look for experience with your situation; a board certification in estate planning, trust or probate law is a strong signal. Most Illinois estate planning attorneys offer an initial consultation, some free and some for a flat fee. Ask up front whether the firm bills by the hour or by package, and what your situation is expected to cost.
