Sometimes, landlords can be confused by the terminology they may hear in the eviction courts in Illinois. When an attorney steps up before a judge in the eviction court, he or she will recite a sort of preamble to the case. After introductions, the plaintiff’s attorney might hand up an eviction notice, a 5 day notice for nonpayment of rent, for example, and will say “your honor, this is a joint action proceeding on a landlord’s five day notice”. Other plaintiff’s attorneys hand up a notice, say a 30 day notice in this case, and say “your honor, this is a single action proceeding on a landlord’s thirty day notice”.
