Questions answered? Let's get started!
This statutory form is meant for use by subcontractors or others who are not directly contracted for work with the property owner.
For residential, owner-occupied projects, the 90-day notice form is the second preliminary notice sent in anticipation of filing a lien (the 60-day notice must be served beforehand sent via certified mail within 60 days from the first furnishing). For a commercial project, the 90-day form is the first notice sent to the owner. Either way, both commercial and residential jobs require the 90-day notice prior to filing a lien. 770 Ill. Comp. Stat. 60/24(a).
The 90-day notice is a demand for payment that must be sent by all contractors, subcontractors, laborers, and material/equipment suppliers who have not directly contracted with the owner or the owner's agent. Note that all eligible workers must send the notice within 90 days after the final furnishing of work or delivery of materials to the jobsite. Id. Any substantial additional or extra work can enlarge the time, but mere corrections of previously completed work will not affect the end date. Be aware the time is 90 days, not three months, so count 90 days from the date labor or materials were last furnished.
Serve the notice either through personal service by using a process server, or use the easier and less expensive option of certified mail. The notice does not have to be recorded but keep track of all dates and confirmations of receipt of service to help create a paper trail if a lien becomes necessary. If the deadlines are near, consider a process server. If mailing, serve the notice by certified mail, return receipt requested on the owner, the mortgage lenders, and the general contractor.
The 90-day notice must be verified which means the contractor's signature represents the contents of the notice are accurate and true. The notice must also be notarized by signing it in front of a licensed Notary Public who affixes his or her seal to the document.

I purchased the Notice of Completion form because the City of Chula Vista did not have a "fillable" version of this form on their website. The Deeds.com version of this form is somewhat different than the City's version (8 numbered paragraphs vs. 11 numbered paragraphs.) However, it contains the same information in a different format. This form provided more blank space to fill in important items- like a long ownership name- than the version on the City's website. The recorder's office was satisfied with this form as I hand-delivered it to the Recorder's Office and they approved it for recording. Overall, I found this form easy to use and found the extra blank space for writing on the form helpful. My one comment for possible improvement is: it would be even more helpful (particularly for attorney users) to have strike-out capability. I would have liked having the ability to strike-out inapplicable portions of long awkward sentences. Still, I would use this form again.
Your feedback means a lot to us. Thank you.

The information and documents received are great. But the communication with customer service is not good at all. I've been waiting three days for them to respond to a question. I don't think they are going too.
Thank you for your feedback. We really appreciate it. Have a great day!

Thought we would just do a quit claim to remove a name on a deed but after read your instruction and all that is needed we decided to meet with a lawyer. Appreciate all the info that you supplied.
Glad to hear that Dianne. We always recommend seeking the advice of a professional if you are not completely sure of what you are doing. Have a great day!
