Estate planning attorneys in Illinois average $334 an hour for wills and estates work. A flat-fee package runs $1,002 to $2,004 for a simple individual will and $3,680 to $5,520 for a basic revocable trust. An online service prices the same documents in the tens to low hundreds of dollars; the Illinois will cost calculator sets the two side by side.

In Illinois, estates with personal property of $150,000 or less skip probate with the Small Estate Affidavit. 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 tax threshold of $4,000,000; 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.

Tax Planning Attorneys in Illinois

Illinois attorneys average $334 an hour for wills and estates work. A basic will from an attorney runs $1,002–$2,004; online services cost $30–$300.

Illinois imposes its own estate tax separate from the federal one, kicking in well below the federal exemption. Estates near the state threshold benefit from real planning — not because every family needs it, but because the line is lower than people expect.

Worth knowing: estates under $150,000 can use Illinois's simplified affidavit instead of formal probate. If your situation is straightforward and the estate fits, you may not need an attorney at all.
