Where the minor gets into the caption

Almost never on purpose. Three routes account for nearly all of it.

“All unknown occupants.” The standard practice of naming unknown occupants to bind everyone in possession is safe as drafted — it does not name a minor. The risk arrives when counsel later amends to substitute actual names gathered from a process server's return or a tenant list, and a household member turns out to be sixteen.

Deceased-owner and heirs-property units. Where title passed by intestacy and the association is chasing the occupants, minor children are commonly among the heirs. This is a real Illinois problem — common enough that the legislature separately created a path for possessory heirs to perfect title in P.A. 104-0506.

Sublease and occupancy-violation cases. Where the association is enforcing a leasing restriction rather than collecting money, counsel often names every occupant to make the order effective. That is exactly the instinct the Act now punishes.

The screening step, and who owns it

Someone has to check ages before filing, and the association is usually the party that holds the information — occupancy registrations, key-fob records, parking registrations, move-in forms. Collection counsel working from a ledger and a title search does not have it.

The practical fix is a pre-filing checklist item: the manager confirms in writing, for each named occupant, that the person is 18 or over or that age is unknown and the person will not be named. It costs a few minutes and it prevents a dismissal that carries the association's own filing fee, its counsel's time, and a potential $1,000 claim against it.

What “willfully and wantonly” is doing

The damages provision is qualified; the dismissal is not. So an association that names a minor by honest mistake still loses the entire case, still gets it sealed, and still pays to refile — it simply avoids the $1,000 and fees. That asymmetry is the reason to treat this as a filing-hygiene rule rather than a liability rule.

The sealing wrinkle

Because the dismissed action is immediately sealed under 9-121, an association cannot later point to the filing as evidence of the delinquency's history, and a subsequent purchaser's counsel will not find it. Boards that rely on a litigation history to justify a hard line on a repeat delinquent should keep their own records rather than the court file.

What to watch next

Whether courts read “names a minor as a defendant” to reach a complaint that names a minor only through an “unknown occupants” designation later given content by an amended caption. The text keys on the complaint “at the time of filing,” which suggests it does not — but no Illinois court has construed it.
