Who - Regarding a customer who repeatedly informs us his brother is a layers. What - Repeatedly has told us he didn't receive insurance depreciation, thus why hasn't paid us, but recently found out that was a lie. Why - The last date worked on the home was 8/1/2019 and want to file a lien against property but need 100% confirmation that this is legal. We are a general contractor. How - If I can legally file do I have to send letter of intent or can i just file in the state of IL? Lastly we never charged late fees based on our terms and conditions thinking he never got the money from the insurance carrier but now that we know he lied, can I add late fees legally to the lien total? Thank you :)
