Illinois probate timeline: when creditor claims close
The waiting-period requirement has not been verified, so no number is published below.
In Illinois, creditors get at least six months after first publication, or three months after mailed notice if later, two years after death at most; each clock is set out below against the event it runs from.

No waiting-period number is published for the small estate affidavit (755 ilcs 5/25-1) route. 755 ILCS 5/25-1 imposes no fixed waiting period after death; the affidavit is available once the value and no-letters conditions are met.

The section’s own words
the decedent's personal estate passing to any party by intestacy or under a will is limited to: (A) excluding motor vehicles registered with the Secretary of State, tangible and intangible personal property not exceeding $150,000; and (B) motor vehicles registered with the Secretary of State.
Creditor deadlines
- From publication of notice to creditors
- Not less than 6 months from the date of first publication of notice (§ 18-3)
- From actual notice to a known creditor
- Not less than 3 months from the date of mailing/delivery of notice to a known creditor, or 6 months from first publication, whichever is later (§ 18-3)
- Outer limit, running from death
- All claims barred 2 years after the decedent's death (§ 18-12)
How these combine. Illinois combines a notice-based bar date (755 ILCS 5/18-3: at least 6 months from first publication or 3 months from mailing, whichever is later) with an independent 2-year outer nonclaim bar from the date of death (755 ILCS 5/18-12). These run from different triggers and cannot honestly collapse into a single day count.

The section’s own words
claims may be filed on or before the date stated in the notice, which date shall be not less than 6 months from the date of the first publication or 3 months from the date of mailing or delivery, whichever is later
Illinois bars a claim by what the notice said, and backstops it at two years
755 ILCS 5/18-12(a) does not state a period at all. Every claim against the estate — "except expenses of administration and surviving spouse’s or child’s award" — is barred as to all of the decedent’s estate if notice was given to the claimant under Section 18-3 and the claimant did not file with the representative or the court "on or before the date stated in the notice." The controlling date is on the document, not in the statute.
Two other routes produce the same bar. A claimant who receives a notice of disallowance under Section 18-11 and does not file with the court by the date stated in that notice is barred. And a claimant whose identity or address "is not known to or reasonably ascertainable by the representative" is barred by the date stated in the published notice under Section 18-3 — which is what makes the publication step matter for the creditors nobody could write to.
Subsection (b) sets the outer limit: "Unless sooner barred under subsection (a) of this Section, all claims which could have been barred under this Section are, in any event, barred 2 years after decedent’s death, whether or not letters of office are issued upon the estate of the decedent." An Illinois estate that was never opened is not therefore an estate without a deadline.
Two carve-outs matter in practice. Subsection (c) preserves actions to establish the decedent’s liability "to the extent the estate is protected by liability insurance," so an insured claim is not cut off by the probate bar. And subsection (d) protects a representative who acts in good faith to determine and notify creditors from personal liability — while still allowing an unbarred claim to be asserted against the estate to the extent assets remain undistributed, and against a distributee who is not a creditor, within limits the subsection goes on to set.
