A private meeting between a mediator and one party during mediation, held separately from the other party, in which disclosures remain confidential unless the party consents to sharing them.
Written by Mediate Editorial TeamLast reviewed
The caucus is one of the mediator's most important tools. When a joint session reaches an
impasse, or when a party needs to speak candidly about something they cannot say in front
of the other side — the real limit of what they will accept, a personal circumstance that
is affecting their position, or a concern they have not voiced — the mediator can call a
private caucus with each party separately.
## What happens in a caucus
In caucus, the mediator can:
- Explore the party's actual interests (as distinct from their stated positions)
- Reality-test the party's assessment of their best alternative to a negotiated agreement
- Hear concerns or information the party is unwilling to share with the other side
- Convey proposals or information between the parties (shuttle diplomacy)
- Help a party prepare to make or receive an offer without losing face
## Confidentiality in caucus
Anything a party tells the mediator in caucus is confidential. The mediator will not share
it with the other party without the disclosing party's explicit consent. This is what makes
caucus useful: a party can be honest about their real bottom line, or about a personal
factor driving their position, without fear that the information will be used against them.
## Not all mediators use caucus the same way
Some mediators rely heavily on caucus and conduct most of the mediation through shuttle
diplomacy with very little joint session time. Others prefer to keep parties in the same
room and reserve caucus for moments where joint discussion has broken down. There is no
universal right approach — the mediator's choice reflects both their style and the dynamics
of the particular dispute.
Mediation is a voluntary, confidential process where a neutral third party helps disputing parties reach their own settlement. Learn how it works, when it applies, and what makes it binding.
