Quick answer
Mediation can help with some disputes, but a mediator is neutral and does not represent either person.
Do now
Identify the specific decisions to resolve and exchange reliable information through an appropriate process. Ask whether the program screens for abuse, intimidation, and unequal access to money. Arrange independent review of any proposed agreement before signing.
Watch for
Mediation does not automatically pause deadlines or turn an agreement into an order. If you cannot speak freely or safely, tell the program privately and seek advice about alternatives.
