Lien Claims by Subcontractor in Illinois
Mechanic's liens are available in Illinois pursuant to the Mechanic's Lien Act compiled under 770 ILCS 60. Liens are generally available for contractors, subcontractors, material or equipment suppliers, architects, and other design professionals. Subcontractors claiming a mechanic's lien should use the specialized form that references the contract between the property owner and the contractor (referred to as his or her agent in the lien claim document).
A lien is a type of property interest, like a mortgage. There are many types of liens such as tax liens, attorneys' liens, and judgment liens. A lien operates by allowing the lienor to make a claim against the property if it is later sold. Therefore, for a sale to occur, the property owner is required to disclose the existence of the lien to any potential purchaser and the sales proceeds must be used to pay off that lien. If the lien exceeds the value of the property this creates something known as a "deficiency," which must be recovered through a lawsuit. The lienor can also force a sale through foreclosure. Illinois only authorizes mechanic's liens on private projects and not those associated with public (government) entities.
When you provide labor or materials as a subcontractor to a general contractor and the general contractor never pays his or her invoice, filing a mechanic's lien is usually the next step in recovering the amount due. Subcontractors must also individually file 60-day (owner-occupied residential projects only) and 90-day notices to access their lien rights under State law. It is also helpful to attach these previous filed documents to the lien claim as exhibits to further support your case.
Mechanic's liens demand strict deadlines and missing the filing date by even one day can cost you your right to a lien. In Illinois, the time to file a lien arises within four (4) months from the last date of furnishing labor or delivered materials to the jobsite pursuant to the contract between the owner and his or her agent (contractor). The four-month period applies to your right against all third parties and subsequent owners. You have two (2) years to file suit against the original owner to foreclose on a mechanic's lien. 770 ILCS 60/9.
The claim for lien must state the parties to the contract and its terms, identify the general contractor and property owner, state a legal description of the owner's property, and state the total amount due and unpaid as of the date the notice is recorded. The lien amount includes the invoice amount owed minus all credits and offsets. A lienor may not include extras such as attorney's fees (unless a suit is filed to enforce the lien) or lost profits but may charge interest measured by the legal rate in Illinois. 770 ILCS 60/1(a).
Before recording the lien, sign it in the presence of a notary public who then notarizes it with his or her seal. The lien should be recorded at the recording office for the county where the property is situated. For residential projects, you must serve the owner with a copy of the recorded lien within ten (10) days' time.
The deadlines for filing a lien are set in stone, and failure to file on time will cost you your right to a lien. Additionally, putting in improper amounts or exaggerating the claim will invalidate the lien. If you lose your lien rights, the only remedy is to sue the property owner under contract law. As lawsuits are expensive, time-consuming, and stressful, this will become a much more challenging endeavor as opposed to enforcing a lien.
Each case is unique. Contact an attorney with specific questions regarding filing a subcontractor's claim or any other issues related to mechanic's liens in Illinois

I wanna give more stars because the required information is there, but the character spacing is disjointed on the first page, rendering a gap-filled, awkward-looking document. Also, the opening parenthesis for the first field on the first page is on the wrong line and is backwards, which sets the wrong tone especially since it's the first thing you have to fill out.
Thank you for your feedback. We really appreciate it. Have a great day!

Ordered the forms I needed for my state and county and everything worked out perfectly. All the forms came with examples (filled in) and very detailed instructions for each block that required an entry. I was able to fill everything out on my computer and save the files for future use, if required. Deeds provides an excellent product. I highly recommend their products and will use their services again.
Thank you for your feedback. We really appreciate it. Have a great day!

Your system is completely unfriendly to the user. There is no clear way, unless you are a lawyer, to go through the the process without making mistakes.
Very disappointed attempted user
Sorry to hear that we failed you Bernadette. We do hope that you were able to find something more suitable to your needs elsewhere.

Not a fan. Filling in the WI RE transfer return was simple enough. However, it downloaded as a DOR file and I can't find a program to open it. So, I have no way to print the form to complete the process.
Thank you for your feedback. We really appreciate it. Have a great day!
