United States · Illinois civil procedure

When must an Illinois party file a supplementary appearance after counsel withdraws?

Unless another attorney is substituted at withdrawal, the party must file a supplementary appearance within twenty-one days after entry of the withdrawal order. State an address for service. Rule 13(c)(5) uses actual order entry, not the withdrawal motion or later notice. A self-represented party may provide an email address under Rule 11(b).

Which qualifications and court directions matter?

Substitute counsel at withdrawal changes this duty: Rule 13(c)(5) excepts the case in which another attorney is substituted for withdrawing counsel at the time of withdrawal. Establish that substitution rather than assuming every withdrawal creates this duty.
The appearance supplies a service address: The supplementary appearance must state an address for notices and documents. A self-represented litigant may provide an email address for service under Rule 11(b).
Failure does not stop subsequent service: If no supplementary appearance is filed, Rule 13(c)(5) directs subsequent notices and filings to the party’s last known business or residence address. Do not assume future proceedings pause.
Written appearances are served separately: Rule 13(a) requires copies of a filed written appearance to be served in the manner required for copies of pleadings.
