When a parent or relative passes away and leaves a house, the property usually has to go through probate in Cook County’s Circuit Court Probate Division before it can be sold. This adds time, paperwork, and sometimes friction between heirs. But the process is more manageable than most people fear.
This guide walks through how probate sales work in Cook County in 2026 — including the difference between independent and supervised administration, when court approval is required, and how to coordinate with multiple heirs.
Independent vs Supervised Administration
Illinois probate comes in two flavors, and which one applies dramatically affects your selling timeline.
Independent administration is the default for most estates. The personal representative (executor or administrator) can sell real estate without court approval as long as no heir objects in writing. This is faster — once you have Letters of Office, you can list and sell.
Supervised administration applies when an heir objects, when the will requires it, or when the court orders it for cause. Every major action — including real estate sales — requires a court petition and order. This adds 30-90 days to any sale.
Letters of Office Are the Starting Gun
Before you can do anything with the house, you need Letters of Office (sometimes called Letters Testamentary or Letters of Administration). This is the court-issued document proving you have authority to act for the estate.
Typical Cook County timeline:
- Days 1-14: File petition for probate and to issue Letters of Office
- Days 14-45: Court reviews, sets hearing date
- Day 45-60: Hearing held, Letters issued if no objection
Add 30-60 days if there are will contests, heir disputes, or missing documents.
The 6-Month Creditor Claim Period
Illinois law gives creditors 6 months from the date of first publication of notice to file claims against the estate. This is a critical window for two reasons:
- You can sell the house during this period — most personal representatives do
- But you generally can’t distribute proceeds to heirs until the period closes (or unless all known creditors are paid)
Practically: sell whenever you’re ready, but keep proceeds in the estate account until month 6 to avoid personal liability if a creditor surfaces.
Multiple Heirs = Multiple Decisions
If the property is left to multiple heirs (siblings inheriting equally, for example), all of them need to be on the same page about selling, pricing, and timing. Common friction points:
- One heir wants to keep the house, others want cash
- Disagreement on listing price (one says “we should hold out for more”)
- One heir refuses to clean out the property
- Property condition disputes
If heirs can’t agree, any heir can file a partition action — but that’s costly, slow, and forces a court-supervised sale. A unanimous cash sale is almost always cheaper than a contested partition.
Property Condition: As-Is Almost Always
Probate properties are almost always sold as-is. Reasons:
- The deceased may have deferred maintenance for years
- The estate may not have funds to do repairs
- Heirs don’t want to invest their own money in a house they’re selling
This makes probate properties a natural fit for cash investor buyers, who buy as-is and don’t need an FHA inspection.
Why Cash Sales Are Common for Cook County Probate
For most Cook County probate situations, selling to a cash investor like Dover Funds is the path of least resistance:
- Close in 14-21 days once Letters of Office are issued
- No repairs, no cleanout (we handle it)
- No financing contingency to fail
- Single buyer to coordinate with — easier when heirs are scattered across the country
- Predictable closing date for estate planning
