Users, contacts, and organizations are three different types of records that represent either people - users and contacts - or agencies, firms, courts, and medical providers in the case of organizations.
Users are people who can be assigned to cases or who need to have time recorded, whether or not they log into your site. Many agencies set up their pro bono attorneys, who may never be allowed to log in, as users so they can be assigned to cases or have time recorded for them.
Contacts are people who are not clients, family members/non-adverse parties, or adverse parties. Some common uses of contacts include opposing counsel, judges, social workers, doctors, contacts in a funding agency or any other . There are a few special types of contacts that connect the contact record to other modules in LegalServer. For example, in the litigation module when inputting a judge, it will search contacts tagged with the 'Judge' contact type. Please be aware that while all users are contacts, contacts are not necessarily users unless they are created through the user creation process.
Organizations are records for law firms, hospitals, courts, and agencies that you may refer cases to or accept referrals from, or any other entity that is not a person that you may want to record actions about. You can assign users to organizations (in the case of pro bono users who may work at a firm or another agency), assign a case to the organization, record referrals to or from an organizations, track donations and record referral information about the organization.
