Illinois divorce forms, with their official numbers
Every divorce form Illinois publishes, listed by the number the clerk will ask
for, with a link to the state’s own file. Nothing here is our document.
This is a reference list, not a packet. If you want the process
— what to file first, what it costs, how long it takes — that is on
the Illinois divorce guide. This page exists because the
number is often the only thing you need: a clerk who says “bring the
Statute” is not going to explain what that is.
revision of the right form is the commonest reason a filing is rejected, and it
is invisible — the form looks correct. A dash in the revision column means the state does not publish a revision date for that form. We show a dash rather than a guess, because a guessed revision date is the single most dangerous thing we could put on this page.

We check every one of these links automatically, and we would rather hear it
from you than find it next week. Tell us
and we will fix it and say when. Sources last checked: 14 September 2026.
Where a form has no revision date or no direct link, the row
still appears, because a number you can quote at a courthouse counter is useful
on its own. We do not host, sell or alter any of these forms; every link goes to
the state’s own file. See also the full
fifty-state form index and the fifty-state
comparison of residency, waiting periods and filing fees.
