Illinois Independent vs Supervised Probate

Independent administration is Illinois's quiet default — most estates never see the inside of a courtroom for routine decisions, unless someone objects.

By the FigureMyTax Editorial Team · How we calculate

Quick answer: most Illinois estates use independent administration — the statutory default, with minimal court involvement, comparatively fast and affordable. Supervised administration, requiring court approval at nearly every step, applies when someone objects, the will requires it, or the court orders it for cause.

Independent administration is the Illinois default

755 ILCS 5/28-1 et seq.: unless the will specifically requires supervision, or an interested party successfully petitions to terminate it, an Illinois estate is administered independently by default — the representative can act without a separate court hearing for most routine steps. This is the primary reason Illinois probate stays comparatively affordable and fast among states without a simplified small-estate track.

When supervision takes over

An interested party can petition to terminate independent administration and require court supervision, generally within a limited window after the representative's appointment. Disputes over the will's validity, disagreement about how the representative is handling assets, or the will itself specifying supervised administration all push an estate onto this slower, more expensive track.

Independent vs supervised — frequently asked questions

What is independent administration in Illinois?

The default track under 755 ILCS 5/28-1, letting the representative handle most estate actions without seeking court approval for each individual step — the main reason Illinois probate is comparatively fast and affordable.

What is supervised administration in Illinois?

A court-supervised track requiring approval for significant actions — selling assets, paying claims, making distributions. It applies when independent administration is contested, when the will requires it, or when the court orders it for cause.

Can Illinois heirs object to independent administration?

Yes. An interested party can file a petition to terminate independent administration and require supervision, generally within a limited window after the representative is appointed — which is why disputes among heirs often mean supervised administration from the start.

Which Illinois probate track is most common?

Independent administration, by a wide margin. It's the statutory default for most estates and courts favor it for uncontested cases, since it reduces both the family's cost and the court's own workload.
