A mediation agreement — the engagement document signed by parties when they retain a mediator — is sometimes treated as a formality. It is not. The agreement governs confidentiality of everything said during the process, allocation of fees, mediator immunity, document handling, and the procedure for converting an oral resolution into an enforceable settlement. Mistakes in the mediation agreement can leak privileged conversations and undermine the enforceability of any settlement reached.
What is a Mediator engagement terms?
A mediation agreement is a contract among the parties and the mediator that sets the procedural framework for the mediation. It typically includes: confidentiality obligations binding the parties and mediator, fee structure and allocation, mediator's role and impartiality, document retention and destruction, mediator's evidentiary immunity, and the form in which any settlement will be reduced to writing. Many US jurisdictions also apply the Uniform Mediation Act (adopted in 12 states plus DC) or state-specific mediation privilege statutes (e.g. California Evidence Code §§ 1115-1129).
Red flags to watch for
Discussions with the mediator before the session — phone calls, emails, position statements — should be covered by the confidentiality umbrella. A narrow clause covering only the session itself leaves preparation discussions exposed.
Reasonable carve-outs exist, but they should include notice obligations so a party can move to quash a subpoena. Open-ended carve-outs gut the confidentiality protection.
Many states grant statutory immunity for mediators (e.g. California Civil Code § 1297.371). Contractual immunity clauses that purport to immunise gross negligence or intentional misconduct are typically unenforceable.
Mediators often charge for cancellations within 14 or 30 days. If the cancellation fee exceeds actual lost opportunity, it may be challenged as a penalty.
A handshake settlement at 8pm on a Friday is often unenforceable in many states unless reduced to a writing signed by the parties before adjournment. The agreement should specify the memorialisation process to avoid post-mediation disputes about whether a settlement was reached.
Med-arb arrangements have specific ethical concerns. Without a clear separation, a mediator who later arbitrates the same dispute may improperly use confidential information from caucus sessions.
The mediator typically destroys notes after the mediation. The agreement should specify the destruction timeline and how documents shared with the mediator are returned or destroyed.
Mediation privilege rules vary significantly by state (California is among the strictest; states that have not adopted the UMA may have weaker protection). The agreement should specify which state's mediation privilege law applies.
Your legal rights
Federal protections include the Federal Arbitration Act for mediated settlements that incorporate arbitration provisions and the Federal Rules of Evidence (Rule 408) excluding compromise negotiations from evidence. State-level frameworks include the Uniform Mediation Act (adopted in DC, IL, IA, NE, NJ, OH, SD, UT, VT, WA, plus partial adoption elsewhere); California Evidence Code §§ 1115-1129 establishing California's strict mediation confidentiality; New York CPLR Rule 4547 on settlement negotiations; Texas Civil Practice and Remedies Code § 154.073 on mediation confidentiality. Statutory mediator immunity statutes apply in most states. The Singapore Convention on Mediation (2019), ratified by the US in 2024, applies to international mediated settlements.
Questions to ask before you sign
- 1Does the confidentiality clause cover pre-mediation communications, the session itself, and post-session follow-up?
- 2What are the carve-outs to confidentiality, and do they include notice obligations to the parties?
- 3What is the mediator's fee, and how is it allocated — equally, by party, or by some other formula?
- 4What is the cancellation policy, and is the fee disproportionate to lost opportunity?
- 5How will a settlement be memorialised — handwritten before adjournment, term sheet, or full agreement post-session?
- 6What is the document retention and destruction process for materials shared with the mediator?
- 7Will the mediator be available later as arbitrator, mediator, or counsel for either party — or is there a strict separation?
- 8Which state's mediation privilege law governs?
