Questions about the Lemont list
Where does this data come from?
The Illinois attorney registry, which the state publishes as a public record. We do not buy or merge third-party compiled lists.
Does every row have an email address?
No — and no honest attorney list has one for every row. The roster on this page carries no email column at all. Where we hold addresses they are sold separately, in our verified email list.
Where do the email addresses come from?
The Illinois bar publishes a member email address on its own record, so most of ours come straight from the registry rather than from a crawl. Either way an address is only sold once it belongs to a named, currently-licensed attorney.
How current is it?
