When must an Illinois public-record inaccuracy affidavit be filed and served?

Obtain the written notice and the particular public-record copy proposed as evidence.

Establish effective service of that notice, rather than a record-production or creation date.

Identify inaccuracies in the actual copy and prepare the required sworn affidavit.

1. Obtain the written notice and the particular public-record copy proposed as evidence.
2. Exclude the independently established triggering day and count intermediate calendar days under 5 ILCS 70/1.11. A filing, entry, effective service or previously established due date must come from its actual record. Do not substitute one event for another.
3. Check statutory holidays and the proper court’s actual calendar.
4. File and serve the affidavit within the period. Point out the copy’s inaccuracies under oath. Preserve the actual file mark, service and proof. File with the proper clerk in the required format. Rule 9 ordinarily requires civil electronic filing, subject to its exceptions and exemptions. Rule 9(f) ordinarily requires submission before midnight in the court time zone unless a statute, rule or actual order specifies a different time. A submission on a closed clerk day ordinarily receives the next open-day stamp. Preserve the actual electronic file mark, receipt and any filing-relief order. Filing and service are distinct acts.

Section 1.11 excludes a final Saturday, Sunday or statutory holiday and consecutive excluded days. Section 17(a) of the Promissory Note and Bank Holiday Act includes Pulaski Day, Good Friday and the general election for members of the House of Representatives. Check proclamations, the proper court’s actual calendar and clerk access separately. The bundled Illinois calendar covers 2026 and 2027.

Fictitious example

Fictitious facts. The adverse party was effectively served with the public-record notice and copy. The established event is August 2, 2027. No additional local closure or different court direction is assumed.

Fictitious facts. The civil procedure classification and triggering event are independently established. No additional closure, court order or unmodeled restart is assumed.

Effective service determines the event

Use Rule 11’s applicable service method and file Rule 12 proof. Rule 12(c) makes electronic or personal delivery service effective on its stated day, mail service complete four days after mailing, and third-party carrier service complete on the third court day after delivery to the carrier. Establish effective service before using a service-triggered calculator. A rule requiring personal or email service cannot be replaced with ordinary mail.

Admissibility remains a separate requirement

Rule 216(d) makes the copy admissible as admitted facts only if otherwise admissible. A date calculation does not establish authenticity, relevance or another evidence requirement.

A requested extension is not an order

Rule 183 permits the court to extend time for good cause on motion after notice, before or after expiration. Preserve the actual order. This calculator does not decide whether the court grants relief.

• The calculator does not decide the applicable civil procedure, disputed facts, sufficiency of a filing or whether the court grants relief.
• Check the governing edition and actual orders. A current rule does not establish every historical case’s timetable.
