Mediation is an informal process of facilitated communication seeking to resolve disputes between individuals or specific entities.  The communication is directed by a mediator - a neutral person who works with the parties exploring opportunities for settlement.  If the mediation is successful, a settlement document (a contract) is signed by the parties describing what issues have been settled and the terms of the settlement.

Mediation sometimes involves conversations in a group with all parties involved - and their counsel - and the mediator, but much of mediation can be done with the mediator visiting with one side at a time.

Mediations generally include lawyers for the parties involved, but no one is required to have a lawyer at a mediation.  And the mediator does not give legal advice at a mediation.
