United States · Illinois civil procedure

When must an Illinois defaulted party respond to notice of new or additional relief?

When new or additional relief is sought against a party not entitled to Rule 104 notice, Rule 105 requires an answer or appearance within thirty days after the applicable service, actual certified or registered mail receipt, or first publication. Exclude that event day. Establish the permitted method and its actual event before calculating.

How is this Illinois civil period counted?

  1. Confirm that the pleading seeks new or additional relief against a party within Rule 105(a)’s notice category.
  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. Complete the particular act in the proper court.

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.

Which qualifications and court directions matter?

Mail notice requires actual receipt
Rule 105(b)(2) requires prepaid certified or registered mail, return receipt requested, showing recipient, delivery date and address. Use restricted delivery for a natural person. Service is not complete until the defendant receives the notice; mailing alone is insufficient.
Publication has limited scope
Rule 105(b)(3) permits publication only in the stated publication cases and upon the required affidavit. Use the first publication date only after establishing that this method is permitted.
The notice and pleading have required content
Rule 105(a) requires a captioned notice directed to the party, describing the filed new or additional relief and thirty-day default warning. Except for publication, attach the new or amended pleading unless the court excuses it for good cause on ex parte application.
Summons-service proof differs from mail proof
Rule 105(b)(1) permits the methods provided by law for summons service. An officer may provide a return; another eligible server provides the stated affidavit or certification of time, manner and place.
