Selling a house in Illinois: the paperwork
Every document an Illinois sale commonly touches, who usually produces it, and the law behind it. In most sales the seller's own share is small, and this page shows you which part that usually is.
Keighbor keeps every one of these in one place, filled in on screen and signed by everyone.

Set up my roomHow Illinois generally runs a sale
The broad shape of a sale there, as the research found it. Counties and cities add their own rules on top of all of this.
Other things Illinois asks about
These come up in Illinois and almost nowhere else. We don't ask them above because we can't answer them for you yet, but they're worth raising with your title company.
- Is the property in Chicago (CRPTT applies)?
- Cook County vs. collar counties (recording and stamp differences)?
- Attorney selected for the review clause?
Before you rely on any of this
This is a compilation of published state requirements, not legal advice, and no lawyer has reviewed it or your sale. Laws and forms change, counties and cities add their own rules, and whether any of this applies to you depends on facts we don't know. Treat every item as a starting point for a question, not as an answer. Confirm anything you plan to rely on against the official source we link, and run your list past a title company or an attorney licensed in your state.
These counts describe a typical sale, not yours. Which documents you need turns on facts about your home, your title, your buyer, and your county, and one unusual answer can add several or remove them.
Who prepares each document is what usually happens, not a rule. Practice differs between states, between counties, and between one title company and the next, and your contract can move work from one side to the other.
Keighbor is not a real estate brokerage and does not represent you. Nobody here is your agent. We don't negotiate, set your price, recommend a course of action, or take a commission. We provide software that helps you organize your side of the sale.
