As these are leads, not cases, there is no implication that you will sign any particular client. A billable lead is someone who fills out a web form and indicated that they have a particular legal issue, are located in your area, and have answered a series of questions correctly (such as noting that they do not have an attorney, or that the accident date was within your states’ statute of limitations). However if someone is in your area and meets all the criteria for a valid lead, that is billable regardless of whether or not they hire you as their attorney.
