Eviction Process Proof

[Account Closed]

Hello Everyone,

I am entered into a contract by providing rehab costs with a house flipper in Illinois (this is my first time investing in real estate).

I am trying to figure out if they are or aren't telling me the truth.

They told me that they started the eviction process by sending a 30 day notice. 

My question is what exact documents should I have them email me to make sure they are telling me the truth?

Thank you, any advice will greatly help (very stressful).
