What mediation means
Mediation is a structured negotiation led by a neutral third party who helps the parents reach agreement rather than deciding for them. It is usually confidential and less adversarial than a hearing, and many courts require parents to attempt it before a judge will hear a contested custody matter.
A mediator does not rule on the facts, but facts still shape the conversation. Walking in with a clear, factual record keeps mediation grounded in what actually happened instead of dissolving into competing memories, and it helps you negotiate from documented ground rather than from feelings.
Example: if scheduling reliability is the sticking point, being able to reference a calm log of the last two months of exchanges moves the discussion toward concrete solutions, like adjusting handoff times, instead of an unwinnable argument about who is more at fault.
Because mediation is often confidential and its rules vary by jurisdiction, ask your attorney what can and cannot be used later; the record you bring is for grounding the discussion, not for scoring points.
