Independent administration: sell without a court order
A specific bequest still needs written consent
Real estate specifically left to a named legatee needs that legatee's written consent before the representative can sell it — this holds even under independent administration and even where the will grants a general power of sale elsewhere.
No statutory fee — just reasonable compensation
755 ILCS 5/27-1 entitles the representative to reasonable compensation, assessed by the court based on the estate's size, complexity, the representative's skill, and the results achieved. Typical fees fall in the 2% to 4% range — a $1,000,000 estate might yield roughly $30,000.
A separate $4 million estate tax question
Illinois taxes estates above a $4 million exemption, frozen since 2013, up to 16% — a completely different calculation from the capital gains tax on a later sale. See Capital Gains Tax on the Sale for that piece.
A long creditor window, either way
Claims must be made within 6 months of first publication or 3 months of mailing notice, whichever is later — and every claim is barred 2 years after death, whether or not letters of office were ever issued.
