Alimony in Peoria: how it is calculated
Alimony in Peoria follows Illinois law, not a local rule — the same statute applies whether the case is filed in Peoria County or anywhere else in the state. Here is what that formula produces, and where a Peoria case is actually heard.

No. 750 ILCS 5/504(b-1) applies across Illinois, so a case from Peoria is decided by the same numbers as one filed anywhere else in the state. What changes locally is the courthouse, the clerk's procedure and how long the docket takes — not the amount.
What the statute says
