Probate Leads for Attorneys in Illinois
Illinois sees approximately ~130,000 deaths per year, with an estimated ~45,000–55,000 resulting in probate or estate administration proceedings. Across the state's 102 counties, each of those cases represents a potential client for estate attorneys who can reach the family in time.
Probate Helper delivers qualified, asset-verified probate leads to Illinois attorneys in real time. Instead of scanning obituaries or waiting for courthouse filings, you receive leads with surviving family contacts, known assets, and estimated estate values — ready for outreach the same week.
How It Works in Illinois
Probate Helper's AI monitors public records and obituary sources across all 102 Illinois counties continuously. When a new death is recorded, the system:
- Identifies the opportunity — flagging deaths that are likely to trigger probate based on the decedent's profile and known asset indicators.
- Enriches the lead — tracing surviving family members, mailing addresses, phone numbers, and property records tied to the decedent. The system estimates estate value based on identified assets.
- Qualifies against your criteria — filtering for minimum estate value, geographic match, and asset composition so you only see leads worth pursuing.
- Delivers to your dashboard — with all the data you need to decide whether to reach out, plus optional managed direct mail that sends compliance-reviewed letters on your firm's behalf.

What Makes Illinois Probate Unique
Illinois is a common law state that follows the Illinois Probate Act of 1975 (755 ILCS 5). The state uses a supervised administration system by default, where the circuit court oversees the executor's actions. However, independent administration under the Independent Administration of Estates Act (755 ILCS 5/28) is far more common in practice and allows the executor to act without court approval for most transactions, provided no interested party objects within specific notice periods.
The small estate affidavit threshold in Illinois is $100,000, one of the higher thresholds nationally. Estates below this amount can transfer assets through a simple affidavit under 755 ILCS 5/25-1 without formal probate. For attorneys, this means the cases that do require probate tend to involve meaningful asset values.
Illinois has a state estate tax for estates above $4 million — significantly lower than the federal exemption. This means many upper-middle-class estates in the Chicago suburbs and North Shore communities trigger state estate tax obligations, creating an additional layer of complexity that drives demand for legal counsel. The tax is graduated, starting at 0.8% and reaching 16% for the largest estates.
Cook County dominates the Illinois probate landscape with far more filings than any other county. The Cook County Circuit Court Probate Division has its own local rules, forms, and procedures that differ substantially from downstate courts. Attorneys practicing in Cook County need familiarity with its particular requirements, while attorneys in collar counties (DuPage, Lake, Will, Kane) deal with a different procedural environment despite geographic proximity.
