We are not attorneys

Lobi Space is not a law firm, and no one on our staff, including our notary public, is an attorney licensed to practice law in Illinois. We prepare and file formation documents only at your direction, using the information you give us. We cannot give legal or tax advice, tell you which entity type to choose, or review your situation the way a lawyer would. For those decisions, talk to an Illinois attorney or a CPA.

Notice from our notary public (Illinois law, 5 ILCS 312/3-103)

I AM NOT AN ATTORNEY LICENSED TO PRACTICE LAW IN ILLINOIS. I AM NOT ALLOWED TO DRAFT LEGAL DOCUMENTS OR RECORDS, NOR MAY I GIVE LEGAL ADVICE ON ANY MATTER, INCLUDING, BUT NOT LIMITED TO, MATTERS OF IMMIGRATION, OR ACCEPT OR CHARGE FEES FOR THE PERFORMANCE OF THOSE ACTIVITIES.
