Full Text of 735 ILCS 5/17-102
Plain-English Summary
This section sets the pleading standard for a partition complaint. It must particularly describe the premises to be divided and set out the interests of every party as far as the plaintiff knows them. That includes not just present co-owners but tenants for years or for life, people entitled to a reversion, remainder, or inheritance, and anyone who might, on some contingency, become entitled to a beneficial interest.
The complaint must close by asking the court to divide and partition the premises according to each party's rights, or, where it applies, in accordance with the Uniform Partition of Heirs Property Act.
Because the section ties the required detail to what the plaintiff knows, a companion section addresses what happens when names, shares, or interests remain unknown or uncertain.
