Quick answer: the ordinary 5-6% realtor commission applies as usual, plus an executor commission set by Court of Chancery rule with no fixed percentage, plus a filing fee that scales widely with estate value. See how this plays out for your own numbers in the Delaware probate real estate sale calculator.
A rule, not a statutory schedule
A filing fee that spans a genuinely wide range
Filing fees start at $30 and can run up to $1,905, based on estate value, under 12 Del. C. §2510 — a much wider spread than the flatter, single-figure filing fees many other states charge.
Attorney fees follow a similar pattern
Attorney fees are negotiated, typically 2% to 4% of estate value, with flat-fee arrangements common for straightforward estates — on top of, not instead of, the executor's own commission.
No state estate or inheritance tax to budget for
Delaware imposes neither, so only the federal estate tax, with its much higher threshold, can apply to a Delaware estate.
A local probate attorney can review your estate — many offer a free consultation.
The §2305 commission rule and the §2510 fee schedule apply the same way whether the Register of Wills is in New Castle, Kent, or Sussex County.
