New York Limited Liability Company Law § 206 states that when an LLC is formed it must publish a legal advertisement of the new business entity for six consecutive weeks in two newspapers. The newspapers are assigned by the County Clerk in the county of the LLC’s legal address. After six weeks of running the ads once per week, each newspaper will issue an affidavit, which is notarized, that restates the ad and the dates that it was run, and these affidavits must be filed with the New York Department of State, along with a Certificate of Publication. This process must be completed within 120 days of the date that the LLC was formed.
